Data science guide from Sense about Science

Sense about Science, headquartered in the UK, is in its own words (from its homepage)

Sense about Science is an independent campaigning charity that challenges the misrepresentation of science and evidence in public life. …

According to an October 1, 2019 announcement from Sense about Science (received via email), the organization has published a new guide,

Our director warned yesterday [September 30, 2019] that data science is being given a free
pass on quality in too many arenas. From flood predictions to mortgage offers to the prediction of housing needs, we are not asking enough about whether AI solutions and algorithms can bear the weight we want to put on them.

It was the UK launch of our ‘Data Science: a guide for society’ at the Institute of Physics, where we invited representatives from different sectors to take up the challenge of creating a more questioning culture. Tracey Brown said the situation was like medicine 50 years ago: it seems that some people have become too clever to explain and the rest of us are feeling too dumb to ask.

At the end of the event we had a lot of proposals for how to make different communities aware of the guide’s three fundamental questions from the people who attended. There are many hundreds of people among our friends who could do something along these lines:

     * Publicise the guide
     * Incorporate it into your own work
     * Send it to people who are involved in procurement, licensing or
reporting or decision making at community, national and international
levels
     * Undertake a project with us to equip particular groups such as
parliamentary advisers, journalists and small charities.

Would you take a look at the guide [1] here and tell me if there’s something you can do? (alex@senseaboutscience.org)

There are launches planned in other countries over the rest of this year and into 2020. We are drawing up a map of offers to reach different communities. I’ll share all your suggestions with my colleague Errin Riley at the end of this week and we will get back to you quickly.

Before linking you to the guide, here’s a brief description from the Patterns in Data webpage,

In recent years, phrases like ‘big data’, ‘machine learning’, ‘algorithms’ and ‘pattern recognition’ have started slipping into everyday discussion. We’ve worked with researchers and experts to generate an open and informed public discussion on patterns in data across a wide range of projects.

Data Science: A guide for society

According to the headlines, we’re in the middle of a ‘data revolution: large, detailed datasets and complex algorithms allow us to make predictions on anything from who will win the league to who is likely to commit a crime. Our ability to question the quality of evidence – as the public, journalists, politicians or decision makers – needs to be expanded to meet this. To know the questions to ask and how to press for clarity about the strengths and weaknesses of using analysis from data models to make decisions. This is a guide to having more of those conversations, regardless of how much you don’t know about data science.

Here’s Data Science: A Guide for Society.

Revival of dead pig brains raises moral questions about life and death

The line between life and death may not be what we thought it was according to some research that was reported in April 2019. Ed Wong’s April 17, 2019 article (behind a paywall) for The Atlantic was my first inkling about the life-death questions raised by some research performed at Yale University, (Note: Links have been removed)

The brain, supposedly, cannot long survive without blood. Within seconds, oxygen supplies deplete, electrical activity fades, and unconsciousness sets in. If blood flow is not restored, within minutes, neurons start to die in a rapid, irreversible, and ultimately fatal wave.

But maybe not? According to a team of scientists led by Nenad Sestan at Yale School of Medicine, this process might play out over a much longer time frame, and perhaps isn’t as inevitable or irreparable as commonly believed. Sestan and his colleagues showed this in dramatic fashion—by preserving and restoring signs of activity in the isolated brains of pigs that had been decapitated four hours earlier.

The team sourced 32 pig brains from a slaughterhouse, placed them in spherical chambers, and infused them with nutrients and protective chemicals, using pumps that mimicked the beats of a heart. This system, dubbed BrainEx, preserved the overall architecture of the brains, preventing them from degrading. It restored flow in their blood vessels, which once again became sensitive to dilating drugs. It stopped many neurons and other cells from dying, and reinstated their ability to consume sugar and oxygen. Some of these rescued neurons even started to fire. “Everything was surprising,” says Zvonimir Vrselja, who performed most of the experiments along with Stefano Daniele.

… “I don’t see anything in this report that should undermine confidence in brain death as a criterion of death,” says Winston Chiong, a neurologist at the University of California at San Francisco. The matter of when to declare someone dead has become more controversial since doctors began relying more heavily on neurological signs, starting around 1968, when the criteria for “brain death” were defined. But that diagnosis typically hinges on the loss of brainwide activity—a line that, at least for now, is still final and irreversible. After MIT Technology Review broke the news of Sestan’s work a year ago, he started receiving emails from people asking whether he could restore brain function to their loved ones. He very much cannot. BrainEx isn’t a resurrection chamber.

“It’s not going to result in human brain transplants,” adds Karen Rommelfanger, who directs Emory University’s neuroethics program. “And I don’t think this means that the singularity is coming, or that radical life extension is more possible than before.”

So why do the study? “There’s potential for using this method to develop innovative treatments for patients with strokes or other types of brain injuries, and there’s a real need for those kinds of treatments,” says L. Syd M Johnson, a neuroethicist at Michigan Technological University. The BrainEx method might not be able to fully revive hours-dead brains, but Yama Akbari, a critical-care neurologist at the University of California at Irvine, wonders whether it would be more successful if applied minutes after death. Alternatively, it could help to keep oxygen-starved brains alive and intact while patients wait to be treated. “It’s an important landmark study,” Akbari says.

Yong notes that the study still needs to be replicated in his article which also probes some of the ethical issues associated with the latest neuroscience research.

Nature published the Yale study,

This paper is behind a paywall.

Two neuroethicists had this to say (link to their commentary in Nature follows) as per an April 71, 2019 news release from Case Western Reserve University (also on EurekAlert), Note: Links have been removed,

The brain is more resilient than previously thought. In a groundbreaking experiment published in this week’s issue of Nature, neuroscientists created an artificial circulation system that successfully restored some functions and structures in donated pig brains–up to four hours after the pigs were butchered at a USDA food processing facility. Though there was no evidence of restored consciousness, brains from the pigs were without oxygen for hours, yet could still support key functions provided by the artificial system. The result challenges the notion that mammalian brains are fully and irreversibly damaged by a lack of oxygen.

“The assumptions have always been that after a couple minutes of anoxia, or no oxygen, the brain is ‘dead,'” says Stuart Youngner, MD, who co-authored a commentary accompanying the study with Insoo Hyun, PhD, both professors in the Department of Bioethics at Case Western Reserve University School of Medicine. “The system used by the researchers begs the question: How long should we try to save people?”

In the pig experiment, researchers used an artificial perfusate (a type of cell-free “artificial blood”), which helped brain cells maintain their structure and some functions. Resuscitative efforts in humans, like CPR, are also designed to get oxygen to the brain and stave off brain damage. After a period of time, if a person doesn’t respond to resuscitative efforts, emergency medical teams declare them dead.

The acceptable duration of resuscitative efforts is somewhat uncertain. “It varies by country, emergency medical team, and hospital,” Youngner said. Promising results from the pig experiment further muddy the waters about the when to stop life-saving efforts.

At some point, emergency teams must make a critical switch from trying to save a patient, to trying to save organs, said Youngner. “In Europe, when emergency teams stop resuscitation efforts, they declare a patient dead, and then restart the resuscitation effort to circulate blood to the organs so they can preserve them for transplantation.”

The switch can involve extreme means. In the commentary, Youngner and Hyun describe how some organ recovery teams use a balloon to physically cut off blood circulation to the brain after declaring a person dead, to prepare the organs for transplantation.

The pig experiment implies that sophisticated efforts to perfuse the brain might maintain brain cells. If technologies like those used in the pig experiment could be adapted for humans (a long way off, caution Youngner and Hyun), some people who, today, are typically declared legally dead after a catastrophic loss of oxygen could, tomorrow, become candidates for brain resuscitation, instead of organ donation.

Said Youngner, “As we get better at resuscitating the brain, we need to decide when are we going to save a patient, and when are we going to declare them dead–and save five or more who might benefit from an organ.”

Because brain resuscitation strategies are in their infancy and will surely trigger additional efforts, the scientific and ethics community needs to begin discussions now, says Hyun. “This study is likely to raise a lot of public concerns. We hoped to get ahead of the hype and offer an early, reasoned response to this scientific advance.”

Both Youngner and Hyun praise the experiment as a “major scientific advancement” that is overwhelmingly positive. It raises the tantalizing possibility that the grave risks of brain damage caused by a lack of oxygen could, in some cases, be reversible.
“Pig brains are similar in many ways to human brains, which makes this study so compelling,” Hyun said. “We urge policymakers to think proactively about what this line of research might mean for ongoing debates around organ donation and end of life care.”

I was hoping to find out more about BrainEx, but this April 17, 2019 US National Institute of Mental Health news release is all I’ve been able to find in my admittedly brief online search. The news release offers more celebration than technical detail.

Interestingly, there hasn’t been much of a furor over this work. Not yet.

October 2019 science and art/science events in Vancouver and other parts of Canada

This is a scattering of events, which I’m sure will be augmented as we properly start the month of October 2019.

October 2, 2019 in Waterloo, Canada (Perimeter Institute)

If you want to be close enough to press the sacred flesh (Sir Martin Rees), you’re out of luck. However, there are still options ranging from watching a live webcast from the comfort of your home to watching the lecture via closed circuit television with other devoted fans at a licensed bistro located on site at the Perimeter Institute (PI) to catching the lecture at a later date via YouTube.

That said, here’s why you might be interested,

Here’s more from a September 11, 2019 Perimeter Institute (PI) announcement received via email,

Surviving the Century
MOVING TOWARD A POST-HUMAN FUTURE
Martin Rees, UK Astronomer Royal
Wednesday, Oct. 2 at 7:00 PM ET

Advances in technology and space exploration could, if applied wisely, allow a bright future for the 10 billion people living on earth by the end of the century.

But there are dystopian risks we ignore at our peril: our collective “footprint” on our home planet, as well as the creation and use of technologies so powerful that even small groups could cause a global catastrophe.

Martin Rees, the UK Astronomer Royal, will explore this unprecedented moment in human history during his lecture on October 2, 2019. A former president of the Royal Society and master of Trinity College, Cambridge, Rees is a cosmologist whose work also explores the interfaces between science, ethics, and politics. Read More.

Mark your calendar! Tickets will be available on Monday, Sept. 16 at 9 AM ET

Didn’t get tickets for the lecture? We’ve got more ways to watch.
Join us at Perimeter on lecture night to watch live in the Black Hole Bistro.

It took me a while to locate an address for PI venue since I expect that information to be part of the announcement. (insert cranky emoticon here) Here’s the address: Perimeter Institute, Mike Lazaridis Theatre of Ideas, 31 Caroline St. N., Waterloo, ON

Before moving onto the next event, I’m including a paragraph from the event description that was not included in the announcement (from the PI Outreach Surviving the Century webpage),

In his October 2 [2019] talk – which kicks off the 2019/20 season of the Perimeter Institute Public Lecture Series – Rees will discuss the outlook for humans (or their robotic envoys) venturing to other planets. Humans, Rees argues, will be ill-adapted to new habitats beyond Earth, and will use genetic and cyborg technology to transform into a “post-human” species.

I first covered Sir Martin Rees and his concerns about technology (robots and cyborgs run amok) in this November 26, 2012 posting about existential risk. He and his colleagues at Cambridge University, UK, proposed a Centre for the Study of Existential Risk, which opened in 2015.

Straddling Sept. and Oct. at the movies in Vancouver

The Vancouver International Film Festival (VIFF) opened today, September 26, 2019. During its run to October 11, 2019 there’ll be a number of documentaries that touch on science. Here are three of the documentaries most closely adhere to the topics I’m most likely to address on this blog. There is a fourth documentary included here as it touches on ecology in a more hopeful fashion than is the current trend.

Human Nature

From the VIFF 2019 film description and ticket page,

One of the most significant scientific breakthroughs in history, the discovery of CRISPR has made it possible to manipulate human DNA, paving the path to a future of great possibilities.

The implications of this could mean the eradication of disease or, more controversially, the possibility of genetically pre-programmed children.

Breaking away from scientific jargon, Human Nature pieces together a complex account of bio-research for the layperson as compelling as a work of science-fiction. But whether the gene-editing powers of CRISPR (described as “a word processor for DNA”) are used for good or evil, they’re reshaping the world as we know it. As we push past the boundaries of what it means to be human, Adam Bolt’s stunning work of science journalism reaches out to scientists, engineers, and people whose lives could benefit from CRISPR technology, and offers a wide-ranging look at the pros and cons of designing our futures.

Resistance Fighters

From the VIFF 2019 film description and ticket page,

Since mass-production in the 1940s, antibiotics have been nothing less than miraculous, saving countless lives and revolutionizing modern medicine. It’s virtually impossible to imagine hospitals or healthcare without them. But after years of abuse and mismanagement by the medical and agricultural communities, superbugs resistant to antibiotics are reaching apocalyptic proportions. The ongoing rise in multi-resistant bacteria – unvanquishable microbes, currently responsible for 700,000 deaths per year and projected to kill 10 million yearly by 2050 if nothing changes – and the people who fight them are the subjects of Michael Wech’s stunning “science-thriller.”

Peeling back the carefully constructed veneer of the medical corporate establishment’s greed and complacency to reveal the world on the cusp of a potential crisis, Resistance Fighters sounds a clarion call of urgency. It’s an all-out war, one which most of us never knew we were fighting, to avoid “Pharmageddon.” Doctors, researchers, patients, and diplomats testify about shortsighted medical and economic practices, while Wech offers refreshingly original perspectives on environment, ecology, and (animal) life in general. As alarming as it is informative, this is a wake-up call the world needs to hear.

Trust Machine: The Story of Blockchain

Strictly speaking this is more of a technology story than science story but I have written about blockchain and cryptocurrencies before so I’m including this. From the VIFF 2019 film description and ticket page,

For anyone who has questions about cryptocurrencies like Bitcoin (and who doesn’t?), Alex Winter’s thorough documentary is an excellent introduction to the blockchain phenomenon. Trust Machine offers a wide range of expert testimony and a variety of perspectives that explicate the promises and the risks inherent in this new manifestation of high-tech wizardry. And it’s not just money that blockchains threaten to disrupt: innovators as diverse as UNICEF and Imogen Heap make spirited arguments that the industries of energy, music, humanitarianism, and more are headed for revolutionary change.

A propulsive and subversive overview of this little-understood phenomenon, Trust Machine crafts a powerful and accessible case that a technologically decentralized economy is more than just a fad. As the aforementioned experts – tech wizards, underground activists, and even some establishment figures – argue persuasively for an embrace of the possibilities offered by blockchains, others criticize its bubble-like markets and inefficiencies. Either way, Winter’s film suggests a whole new epoch may be just around the corner, whether the powers that be like it or not.

The Great Green Wall

For a little bit of hope, From the VIFF 2019 film description and ticket page,

“We must dare to invent the future.” In 2007, the African Union officially began a massively ambitious environmental project planned since the 1970s. Stretching through 11 countries and 8,000 km across the desertified Sahel region, on the southern edges of the Sahara, The Great Green Wall – once completed, a mosaic of restored, fertile land – would be the largest living structure on Earth.

Malian musician-activist Inna Modja embarks on an expedition through Senegal, Mali, Nigeria, Niger, and Ethiopia, gathering an ensemble of musicians and artists to celebrate the pan-African dream of realizing The Great Green Wall. Her journey is accompanied by a dazzling array of musical diversity, celebrating local cultures and traditions as they come together into a community to stand against the challenges of desertification, drought, migration, and violent conflict.

An unforgettable, beautiful exploration of a modern marvel of ecological restoration, and so much more than a passive source of information, The Great Green Wall is a powerful call to take action and help reshape the world.

AI (artificial intelligence) and a hummingbird robot

Every once in a while I stumble across a hummingbird robot story (my August 12, 2011 posting and my August 1, 2014 posting). Here’s what the hummingbird robot looks like now (hint: there’s a significant reduction in size),

Caption: Purdue University researchers are building robotic hummingbirds that learn from computer simulations how to fly like a real hummingbird does. The robot is encased in a decorative shell. Credit: Purdue University photo/Jared Pike

I think this is the first time I’ve seen one of these projects not being funded by the military, which explains why the researchers are more interested in using these hummingbird robots for observing wildlife and for rescue efforts in emergency situations. Still, they do acknowledge theses robots could also be used in covert operations.

From a May 9, 2019 news item on ScienceDaily,

What can fly like a bird and hover like an insect?

Your friendly neighborhood hummingbirds. If drones had this combo, they would be able to maneuver better through collapsed buildings and other cluttered spaces to find trapped victims.

Purdue University researchers have engineered flying robots that behave like hummingbirds, trained by machine learning algorithms based on various techniques the bird uses naturally every day.

This means that after learning from a simulation, the robot “knows” how to move around on its own like a hummingbird would, such as discerning when to perform an escape maneuver.

Artificial intelligence, combined with flexible flapping wings, also allows the robot to teach itself new tricks. Even though the robot can’t see yet, for example, it senses by touching surfaces. Each touch alters an electrical current, which the researchers realized they could track.

“The robot can essentially create a map without seeing its surroundings. This could be helpful in a situation when the robot might be searching for victims in a dark place — and it means one less sensor to add when we do give the robot the ability to see,” said Xinyan Deng, an associate professor of mechanical engineering at Purdue.

The researchers even have a video,

A May 9, 2019 Purdue University news release (also on EurekAlert), which originated the news item, provides more detail,


The researchers [presented] their work on May 20 at the 2019 IEEE International Conference on Robotics and Automation in Montreal. A YouTube video is available at https://www.youtube.com/watch?v=hl892dHqfA&feature=youtu.be. [it’s the video I’ve embedded in the above]

Drones can’t be made infinitely smaller, due to the way conventional aerodynamics work. They wouldn’t be able to generate enough lift to support their weight.

But hummingbirds don’t use conventional aerodynamics – and their wings are resilient. “The physics is simply different; the aerodynamics is inherently unsteady, with high angles of attack and high lift. This makes it possible for smaller, flying animals to exist, and also possible for us to scale down flapping wing robots,” Deng said.

Researchers have been trying for years to decode hummingbird flight so that robots can fly where larger aircraft can’t. In 2011, the company AeroVironment, commissioned by DARPA, an agency within the U.S. Department of Defense, built a robotic hummingbird that was heavier than a real one but not as fast, with helicopter-like flight controls and limited maneuverability. It required a human to be behind a remote control at all times.

Deng’s group and her collaborators studied hummingbirds themselves for multiple summers in Montana. They documented key hummingbird maneuvers, such as making a rapid 180-degree turn, and translated them to computer algorithms that the robot could learn from when hooked up to a simulation.

Further study on the physics of insects and hummingbirds allowed Purdue researchers to build robots smaller than hummingbirds – and even as small as insects – without compromising the way they fly. The smaller the size, the greater the wing flapping frequency, and the more efficiently they fly, Deng says.

The robots have 3D-printed bodies, wings made of carbon fiber and laser-cut membranes. The researchers have built one hummingbird robot weighing 12 grams – the weight of the average adult Magnificent Hummingbird – and another insect-sized robot weighing 1 gram. The hummingbird robot can lift more than its own weight, up to 27 grams.

Designing their robots with higher lift gives the researchers more wiggle room to eventually add a battery and sensing technology, such as a camera or GPS. Currently, the robot needs to be tethered to an energy source while it flies – but that won’t be for much longer, the researchers say.

The robots could fly silently just as a real hummingbird does, making them more ideal for covert operations. And they stay steady through turbulence, which the researchers demonstrated by testing the dynamically scaled wings in an oil tank.

The robot requires only two motors and can control each wing independently of the other, which is how flying animals perform highly agile maneuvers in nature.

“An actual hummingbird has multiple groups of muscles to do power and steering strokes, but a robot should be as light as possible, so that you have maximum performance on minimal weight,” Deng said.

Robotic hummingbirds wouldn’t only help with search-and-rescue missions, but also allow biologists to more reliably study hummingbirds in their natural environment through the senses of a realistic robot.

“We learned from biology to build the robot, and now biological discoveries can happen with extra help from robots,” Deng said.
Simulations of the technology are available open-source at https://github.com/

Early stages of the work, including the Montana hummingbird experiments in collaboration with Bret Tobalske’s group at the University of Montana, were financially supported by the National Science Foundation.

The researchers have three paper on arxiv.org for open access peer review,

Learning Extreme Hummingbird Maneuvers on Flapping Wing Robots
Fan Fei, Zhan Tu, Jian Zhang, and Xinyan Deng
Purdue University, West Lafayette, IN, USA
https://arxiv.org/abs/1902.0962

Biological studies show that hummingbirds can perform extreme aerobatic maneuvers during fast escape. Given a sudden looming visual stimulus at hover, a hummingbird initiates a fast backward translation coupled with a 180-degree yaw turn, which is followed by instant posture stabilization in just under 10 wingbeats. Consider the wingbeat frequency of 40Hz, this aggressive maneuver is carried out in just 0.2 seconds. Inspired by the hummingbirds’ near-maximal performance during such extreme maneuvers, we developed a flight control strategy and experimentally demonstrated that such maneuverability can be achieved by an at-scale 12- gram hummingbird robot equipped with just two actuators. The proposed hybrid control policy combines model-based nonlinear control with model-free reinforcement learning. We use model-based nonlinear control for nominal flight control, as the dynamic model is relatively accurate for these conditions. However, during extreme maneuver, the modeling error becomes unmanageable. A model-free reinforcement learning policy trained in simulation was optimized to ‘destabilize’ the system and maximize the performance during maneuvering. The hybrid policy manifests a maneuver that is close to that observed in hummingbirds. Direct simulation-to-real transfer is achieved, demonstrating the hummingbird-like fast evasive maneuvers on the at-scale hummingbird robot.

Acting is Seeing: Navigating Tight Space Using Flapping Wings

https://arxiv.org/abs/1902.0868

Wings of flying animals can not only generate lift and control torques but also can sense their surroundings. Such dual functions of sensing and actuation coupled in one element are particularly useful for small sized bio-inspired robotic flyers, whose weight, size, and power are under stringent constraint. In this work, we present the first flapping-wing robot using its flapping wings for environmental perception and navigation in tight space, without the need for any visual feedback. As the test platform, we introduce the Purdue Hummingbird, a flapping-wing robot with 17cm wingspan and 12 grams weight, with a pair of 30-40Hz flapping wings driven by only two actuators. By interpreting the wing loading feedback and its variations, the vehicle can detect the presence of environmental changes such as grounds, walls, stairs, obstacles and wind gust. The instantaneous wing loading can be obtained through the measurements and interpretation of the current feedback by the motors that actuate the wings. The effectiveness of the proposed approach is experimentally demonstrated on several challenging flight tasks without vision: terrain following, wall following and going through a narrow corridor. To ensure flight stability, a robust controller was designed for handling unforeseen disturbances during the flight. Sensing and navigating one’s environment through actuator loading is a promising method for mobile robots, and it can serve as an alternative or complementary method to visual perception.

Flappy Hummingbird: An Open Source Dynamic Simulation of Flapping Wing Robots and Animals

https://arxiv.org/abs/1902.0962

Insects and hummingbirds exhibit extraordinary flight capabilities and can simultaneously master seemingly conflicting goals: stable hovering and aggressive maneuvering, unmatched by small scale man-made vehicles. Flapping Wing Micro Air Vehicles (FWMAVs) hold great promise for closing this performance gap. However, design and control of such systems remain challenging due to various constraints. Here, we present an open source high fidelity dynamic simulation for FWMAVs to serve as a testbed for the design, optimization and flight control of FWMAVs. For simulation validation, we recreated the hummingbird-scale robot developed in our lab in the simulation. System identification was performed to obtain the model parameters. The force generation, open- loop and closed-loop dynamic response between simulated and experimental flights were compared and validated. The unsteady aerodynamics and the highly nonlinear flight dynamics present challenging control problems for conventional and learning control algorithms such as Reinforcement Learning. The interface of the simulation is fully compatible with OpenAI Gym environment. As a benchmark study, we present a linear controller for hovering stabilization and a Deep Reinforcement Learning control policy for goal-directed maneuvering. Finally, we demonstrate direct simulation-to-real transfer of both control policies onto the physical robot, further demonstrating the fidelity of the simulation.

Enjoy!

Detecting off-target effects of CRISPR gene-editing

In amidst all the hyperbole about CRISPR (clustered regularly interspaced short palindromic repeats), the gene editing technology, you will sometimes find a mild cautionary note. It seems that CRISPR is not as precise as you might think.

Some months ago there was a story about research into detecting possible unanticipated (off target) effects from using CRISPR, from an April 19, 2019 news item on ScienceDaily,

Since the CRISPR genome editing technology was invented in 2012, it has shown great promise to treat a number of intractable diseases. However, scientists have struggled to identify potential off-target effects in therapeutically relevant cell types, which remains the main barrier to moving therapies to the clinic. Now, a group of scientists at the Gladstone Institutes and the Innovative Genomics Institute (IGI), with collaborators at AstraZeneca, have developed a reliable method to do just that.

An April 19, 2019 Gladstone Institutes press release by Julie Langelier, which originated the press release, provides details,

CRISPR edits a person’s genome by cutting the DNA at a specific location. The challenge is to ensure the tool doesn’t also make cuts elsewhere along the DNA—damage referred to as “off-target effects,” which could have unforeseen consequences.

In a study published in the journal Science, the two first authors, Beeke Wienert and Stacia Wyman, found a new way to approach the problem.

“When CRISPR makes a cut, the DNA is broken,” says Wienert, PhD, who began the work in Jacob E. Corn’s IGI laboratory and who is now a postdoctoral scholar in Bruce R. Conklin’s laboratory at Gladstone. “So, in order to survive, the cell recruits many different DNA repair factors to that particular site in the genome to fix the break and join the cut ends back together. We thought that if we could find the locations of these DNA repair factors, we could identify the sites that have been cut by CRISPR.”

To test their idea, the researchers studied a panel of different DNA repair factors. They found that one of them, called MRE11, is one of the first responders to the site of the cut. Using MRE11, the scientists developed a new technique, named DISCOVER-Seq, that can identify the exact sites in the genome where a cut has been made by CRISPR.

“The human genome is extremely large—if you printed the entire DNA sequence, you would end up with a novel as tall as a 16-story building,” explains Conklin, MD, senior investigator at Gladstone and deputy director at IGI. “When we want to cut DNA with CRISPR, it’s like we’re trying to remove one specific word on a particular page in that novel.”

“You can think of the DNA repair factors as different types of bookmarks added to the book,” Conklin adds. “While some may bookmark an entire chapter, MRE11 is a bookmark that drills down to the exact letter than has been changed.”

Different methods currently exist to detect CRISPR off-target effects. However, they come with limitations that range from producing false-positive results to killing the cells they’re examining. In addition, the most common method used to date is currently limited to cultured cells in the laboratory, excluding its use in patient-derived stem cells or animal tissue.

“Because our method relies on the cell’s natural repair process to identify cuts, it has proven to be much less invasive and much more reliable,” says Corn, PhD, who now runs a laboratory at ETH Zurich. “We were able to test our new DISCOVER-Seq method in induced pluripotent stem cells, patient cells, and mice, and our findings indicate that this method could potentially be used in any system, rather than just in the lab.”

The DISCOVER-Seq method, by being applied to new cell types and systems, has also revealed new insights into the mechanisms used by CRISPR to edit the genome, which will lead to a better understanding of the biology of how this tool works.

“The new method greatly simplifies the process of identifying off-target effects while also increasing the accuracy of the results,” says Conklin, who is also a professor of medical genetics and molecular pharmacology at UC San Francisco (UCSF). “This could allow us to better predict how genome editing would work in a clinical setting. As a result, it represents an essential step in improving pre-clinical studies and bringing CRISPR-based therapies closer to the patients in need.”

Before getting to the link and citation that I usually offer you might find this July 17, 2018 posting, The CRISPR ((clustered regularly interspaced short palindromic repeats)-CAS9 gene-editing technique may cause new genetic damage kerfuffle of interest. I wonder if this latest news affected the CRISPR market as the did the news in 2018.

In addition to the link in the press release, I am including a link and a citation for the study,

Money

Over the last 10 or more years, I have, on occasion made a point, of finding out about the funding for various non-profit agencies and projects. I find that sort of thing interesting and have hoped that my readers might feel the same way.

It seems that my readers and I might not be the only ones to care about the source of funding. Joi Ito who held appointments with Harvard University and the Massachusetts Institute of Technology (MIT) resigned from his various appointments on Sept. 7, 2019 after news of major donations from Jeffrey Epstein (a disgraced financier and sex offender) to MIT were revealed. From the Joi Ito’s entry on Wikipedia (Note: Links have been removed),

Joichi “Joi” Ito (伊藤 穰一 Itō Jōichi, born June 19, 1966) is a Japanese activist, entrepreneur and venture capitalist. He is the former director of the MIT Media Lab, and a former professor of the practice of media arts and sciences at MIT. He is a former visiting professor of practice at the Harvard Law School.[1][2]

Ito has received recognition for his role as an entrepreneur focused on Internet and technology companies and has founded, among other companies, PSINet Japan, Digital Garage and Infoseek Japan. Ito is a strategic advisor to Sony Corporation[3] and general partner of Neoteny Labs.[4] Ito writes a monthly column in the Ideas section of Wired.[5]

Ito resigned from his roles at MIT, Harvard, the John D. and Catherine T. MacArthur Foundation, the Knight Foundation, PureTech Health and The New York Times Company on September 7, 2019, following allegations of financial ties to sex offender and financier Jeffrey Epstein.[2][6][7]

Many, many institutions have accepted funds from sketchy characters and orgnaizations. It’s not new to academia, the sciences, or the arts. For a contemporary view of how some of this works, take a look at Anand Giridharadas’s 2018 book, Winners Take All. From the webepage for the book,

WINNERS TAKE ALL
The Elite Charade of Changing the World
 
An insider’s groundbreaking investigation of how the global elite’s efforts to “change the world” preserve the status quo and obscure their role in causing the problems they later seek to solve.

Former New York Times columnist Anand Giridharadas takes us into the inner sanctums of a new gilded age, where the rich and powerful fight for equality and justice any way they can–except ways that threaten the social order and their position atop it. We see how they rebrand themselves as saviors of the poor; how they lavishly reward “thought leaders” who redefine “change” in winner-friendly ways; and how they constantly seek to do more good, but never less harm. We hear the limousine confessions of a celebrated foundation boss; witness an American president hem and haw about his plutocratic benefactors; and attend a cruise-ship conference where entrepreneurs celebrate their own self-interested magnanimity.

I don’t recall any mention of Epstein in Giridharadas’s book but he did have this to say on Twitter about Epstein,

Anand Giridharadas‏Verified account @AnandWrites



Everything that made Epstein’s life possible remains in place after his arrest: the Caribbean tax havens, the hidden real-estate deals, the buying of politicians, the nonprofits that sell reputational glow, the editors who cover for people of their class.

7:34 PM – 8 Jul 2019

it can’t be easy to withstand the temptation to take the money and hope that the misdoings have been exaggerated or that they have stopped. I imagine Ito and others are under constant pressure to get funds.

AstraZeneca

One of the partners in this research about CRISPR, AstraZeneca, is a pharmaceutical company. In fact, it’s one of the largest in the world (from the AstraZeneca Wikipedia entry; Note: Links have been removed),

AstraZeneca plc[4] is a British-Swedish multinational pharmaceutical and biopharmaceutical company. In 2013, it moved its headquarters to Cambridge, UK, and concentrated its R&D in three sites: Cambridge; Gaithersburg, Maryland, USA (location of MedImmune) for work on biopharmaceuticals; and Mölndal (near Gothenburg) in Sweden, for research on traditional chemical drugs.[5] AstraZeneca has a portfolio of products for major disease areas including cancer, cardiovascular, gastrointestinal, infection, neuroscience, respiratory and inflammation.[6]

The company was founded in 1999 through the merger of the Swedish Astra AB and the British Zeneca Group[7][8] (itself formed by the demerger of the pharmaceutical operations of Imperial Chemical Industries in 1993). Since the merger it has been among the world’s largest pharmaceutical companies and has made numerous corporate acquisitions, including Cambridge Antibody Technology (in 2006), MedImmune (in 2007), Spirogen (in 2013) and Definiens (by MedImmune in 2014).

Controversies

Seroquel
In April 2010 AstraZeneca settled a qui tam lawsuit brought by Stefan P. Kruszewski for $520 million to settle allegations that the company defrauded Medicare, Medicaid, and other government-funded health care programs in connection with its marketing and promotional practices for the blockbuster atypical antipsychotic, Seroquel.[76]
In March 2011, AstraZeneca settled a lawsuit in the United States totalling $68.5 million to be divided up to 38 states.[77]
Nexium
The company’s most commercially successful medication is esomeprazole (Nexium). The primary uses are treatment of gastroesophageal reflux disease, treatment and maintenance of erosive esophagitis, treatment of duodenal ulcers caused by Helicobacter pylori, prevention of gastric ulcers in those on chronic NSAID therapy, and treatment of gastrointestinal ulcers associated with Crohn’s disease. When it is manufactured the result is a mixture of two mirror-imaged molecules, R and S. Two years before the omeprazole patent expired, AstraZeneca patented S-omeprazole in pure form, pointing out that since some people metabolise R-omeprazole slowly, pure S-omeprazole treatment would give higher dose efficiency and less variation between individuals.[78] In March 2001, the company began to market Nexium, as it would a brand new drug.[79]

In 2007, Marcia Angell, former editor-in-chief of the New England Journal of Medicine and a lecturer in social medicine at the Harvard Medical School, said in Stern, a German-language weekly newsmagazine, that AstraZeneca’s scientists had misrepresented their research on the drug’s efficiency, saying “Instead of using presumably comparable doses [of each drug], the company’s scientists used Nexium in higher dosages. They compared 20 and 40 mg Nexium with 20 mg Prilosec. With the cards having been marked in that way, Nexium looked like an improvement – which however was only small and shown in only two of the three studies.”[83]
Bildman fraud, and faithless servant clawback

Study
In 2004, University of Minnesota research participant Dan Markingson committed suicide while enrolled in an industry-sponsored pharmaceutical trial comparing three FDA-approved atypical antipsychotics: Seroquel (quetiapine), Zyprexa (olanzapine), and Risperdal (risperidone). University of Minnesota Professor of Bioethics Carl Elliott noted that Markingson was enrolled in the study against the wishes of his mother, Mary Weiss, and that he was forced to choose between enrolling in the study or being involuntarily committed to a state mental institution.[89] Further investigation revealed financial ties to AstraZeneca by Markingson’s psychiatrist, Stephen C. Olson, oversights and biases in AstraZeneca’s trial design, and the inadequacy of university Institutional Review Board (IRB) protections for research subjects.[90][unreliable source?] A 2005 FDA investigation cleared the university. Nonetheless, controversy around the case has continued. A Mother Jones article[89] resulted in a group of university faculty members sending a public letter to the university Board of Regents urging an external investigation into Markingson’s death.[91]

Is it ok to take money and/or other goods and services from them?

Innovative Genomics Institute (IGI)

Also mentioned as a partner in the research, is the Innovative Genomics Institute (IGI). Here’s more from the company’s Overview webpage (Note: Links have been removed),,

The IGI began in 2014 through the Li Ka Shing Center for Genetic Engineering, which was created thanks to a generous donation from the Li Ka Shing Foundation. [emphasis mine] The Innovative Genomics Initiative formed as a partnership between the University of California, Berkeley and the University of California, San Francisco. Combining the fundamental research expertise and the biomedical talent at UCB and UCSF, the Innovative Genomics Initiative focused on unraveling the mechanisms underlying CRISPR-based genome editing and applying this technology to improve human health. Early achievements include improving the efficiency of gene replacement and foundational work toward a treatment for sickle cell disease.

In late 2015, generous philanthropic donations enabled a bolder vision and broader mission for the IGI. With this expansion came a significant enhancement of the organization, and in January 2017, the IGI officially re-launched as the Innovative Genomics Institute.

As it turns out, there is a Li Ka-shing and he has a bit of a history with Vancouver (Canada). First, here’s more about him from the Li Ka-shing Wikipedia entry,(Note: Links have been removed),

Sir Li Ka-shing GBM KBE JP[4] (born 13 June 1928)[5][6] is a Hong Kong business magnate, investor, and philanthropist. As of June 2019, Li is the 30th richest person in the world, with an estimated net wealth of US$29.4 billion.[3] He is the senior advisor for CK Hutchison Holdings,[7] after he retired from the Chairman of the Board in May 2018;[8] through it, he is the world’s leading port investor, developer, and operator of the largest health and beauty retailer in Asia and Europe.[9]

Besides business through his flagship companies Cheung Kong Property Holdings and CK Hutchison Holdings Limited, Li Ka-shing has also personally invested extensively in real estate in Singapore and Canada. He was the single largest shareholder of Canadian Imperial Bank of Commerce (CIBC), the fifth largest bank in Canada, until the sale of his share in 2005 (with all proceedings donated, see below). He is also the majority shareholder of a major energy company, Husky Energy, based in Alberta, Canada.[48]

In January 2005, Li announced plans to sell his $1.2 billion CAD stake in the Canadian Imperial Bank of Commerce, with all proceeds going to private charitable foundations established by Li, including the Li Ka Shing Foundation in Hong Kong and the Li Ka Shing (Canada) Foundation based in Toronto, Ontario.[49]

His son Victor Li was kidnapped in 1996 on his way home after work by gangster “Big Spender” Cheung Tze-keung. Li Ka-shing paid a ransom of HK$1 billion, directly to Cheung who had come to his house.[53] A report was never filed with Hong Kong police. Instead the case was pursued by Mainland authorities, leading to Cheung’s execution in 1998, an outcome not possible under Hong Kong law. Rumours circulated of a deal between Li and the Mainland.[53] In interviews, when this rumor was brought up, Li brushed it off and dismissed it completely.

Li Ka-shing was well known here in Vancouver due to his purchase of a significant chunk of land in the city. This January 9, 2015 article by Glen Korstrum for Business in Vancouver notes some rather interesting news and contextualizes with Li’s Vancouver history,

Hong Kong billionaire Li Ka-shing is restructuring his empire and shifting his base to the Cayman Islands and away from the Chinese special administrative region.

His January 9 [2015] announcement came the same day that Forbes ranked him as Hong Kong’s richest man for the 17th consecutive year, with a total wealth of US$33.5 billion.

Li is best known in Vancouver for buying an 82.5-hectare parcel of land around False Creek for $328 million in 1988 along with partners, who included fellow Hong Kong tycoons, Lee Shau Kee and Cheng Yu Tung.

The group formed Concord Pacific, which redeveloped the site that had been home to Vancouver’s 1986 world’s fair, Expo ’86.

Li cashed out of Concord Pacific in the late 1990s and, in 2007, invested in Deltaport through his Hutchison Port Holdings.

Li’s biggest Canadian holding is his controlling stake in Husky Energy. …

Intriguing, yes? It also makes the prospect of deciding whose money you’re going to accept a bit more complicated than it might seem.

Gladstone Institutes

In what seems to be a decided contrast to the previous two partners, here’s more from the Gladstone Institutes, About Us, History webpage,

Born in London in 1910, J. David Gladstone was orphaned as a boy and came to North America at age 10. He began a career in real estate in Southern California at age 28, eventually making his fortune as the first developer to create the region’s enclosed shopping malls (such as the Northridge Fashion Center mall). His accidental death in 1971 left an estate valued at about $8 million to support medical students interested in research.

It soon became clear to the three trustees administering Mr. Gladstone’s trust that his legacy could support a far more substantial philanthropic enterprise. In 1979, they launched The J. David Gladstone Institutes under the leadership of Robert W. Mahley, MD, PhD, a leading cardiovascular scientist who at the time was working at the National Institutes of Health.

In 2010, after three decades of leading Gladstone, Dr. Mahley stepped down in order to return to more active research. That same year, R. Sanders “Sandy” Williams, MD, left Duke University, where he had been Dean of the School of Medicine—as well as Senior Vice Chancellor and Senior Advisor for International Strategy—to become Gladstone’s new president. The following year, the S.D. Bechtel, Jr. Foundation [emphasis mine] helped launch the Center for Comprehensive Alzheimer’s Disease Research with a generous $6M lead gift, while the Roddenberry Foundation [emphasis mine] gave $5 million to launch the Roddenberry Center for Stem Cell Biology and Medicine. Also in 2011, the independent and philanthropic Gladstone Foundation formed with the mission of expanding the financial resources available to drive’s Gladstone’s mission.

The S. D. Bechtel jr. mentioned is associated with Bechtel, an international engineering firm. I did not find any scandals or controversies in the Bechtel Wikipedia entry. That seemed improbable so I did a little digging and found a January 30, 2015 (?) article by Matthew Brunwasser for foreignpolicy.com (Note: A link has been removed),

Steamrolled; A special investigation into the diplomacy of doing business abroad.

One of Europe’s poorest countries wanted a road, so U.S. mega-contractor Bechtel sold it a $1.3 billion highway, with the backing of a powerful American ambassador. Funny thing is, the highway is barely being used—and the ambassador is now working for Bechtel.

Bechtel, the largest contractor by revenue in the United States and the third-largest internationally, according to an annual list compiled by the Engineering News-Record, has in recent years constructed expensive highways in Kosovo, Croatia, Romania, and Albania. A six-month investigation by the Investigative Reporting Program at the University of California at Berkeley Graduate School of Journalism has found that these highways were boondoggles for the countries in which they were constructed, and that members of governments and international institutions often saw problems coming before Bechtel (along with its Turkish joint venture partner, Enka) even began work on the roads.

My other source is a May 8, 1988 article by Walter Russell Mead for the Los Angeles Time,s

From San Francisco to Saudi Arabia, the Bechtel Group Inc. has left its mark around the world. Yet the privately owned Bechtel Group is one of the country’s most mysterious operations–or was, until the publication of Laton McCartney’s critical and controversial “Friends in High Places.”

Those who believe that “Dynasty” and “Falcon Crest” describe life at the top of America’s corporate pyramids will find a picture here that makes the most far-fetched TV plots look dull. One Bechtel executive was torn to pieces by an angry mob; another, kidnaped, survived two days in the trunk of a Mercedes that had been driven over the edge of a cliff but caught on an obstacle half way down. Wheeling and dealing from Beirut to the Bohemian Grove, Bechtel executives fought off Arab and Jewish nationalists, angry senators, bitter business rivals, and furious consumer groups to build the world’s largest construction and engineering firm.

Poor Bechtel sometimes seems damned if it does and damned if it doesn’t. No major corporation could undertake foreign operations on Bechtel’s scale without some cooperation from the U.S. government–and few companies could refuse a government request that, in return, they provide cover for intelligence agents. Given the enormous scope of Bechtel’s operations in global trouble spots–a $20-billion industrial development in Saudi Arabia, for example–it could only proceed with assurances that its relations with both Saudi and American governments were good. Where, exactly, is the line between right and wrong? [emphasis mine]

… The white elephants Bechtel scattered across the American landscape–particularly the nuclear power plants that threaten to bankrupt some of the country’s largest utility systems–are monuments to wasted talent and misdirected resources.

Finally, I get to the Roddenberry Foundation, which was founded by Gene Roddenberry’s (Star Trek) son. Here’s more from the About Us, Origin webpage,

Gene Roddenberry, creator of the Star Trek series, brought to his audiences meaningful and thought-provoking science fiction to “think, question, and challenge the status quo” with the intention of creating “a brighter future”. His work has touched countless lives and continues to entertain and inspire audiences worldwide. In 2010, Gene’s son Rod established the Roddenberry Foundation to build on his father’s legacy and philosophy of inclusion, diversity, and respect for life to drive social change and meaningfully improve the lives of people around the world.

While there are many criticisms of Mr. Roddenberry, there doesn’t seem to be anything that would be considered a serious scandal on the order of a Jeffrey Epstein or the whisper of scandal on the order of Sir Li Ka-shing or Bechtel.

Final comments

It’s a good thing when research is funded and being able to detect off-target effects from CRISPR is very good, assuming the research holds up to closer scrutiny.

As for vetting your donors, that’s tricky. Of course, Epstein was already a convicted sex offender when Ito accepted his funding for MIT but I cannot emphasize enough the amount of pressure these folks are under. Academia is always hungry for money. Hopefully this incident will introduce checks and balances in the donor process.

Transmissions; a multimedia installation in Vancouver, September 6 -28, 2019

Here’s a description for the multimedia installation, Transmissions, in the August 28, 2019 Georgia Straight article by Janet Smith,

Lisa Jackson is a filmmaker, but she’s never allowed that job description to limit what she creates or where and how she screens her works.

The Anishinaabe artist’s breakout piece was last year’s haunting virtual-reality animation Biidaaban: First Light. In its eerie world, one that won a Canadian Screen Award, nature has overtaken a near-empty, future Toronto, with trees growing through cracks in the sidewalks, vines enveloping skyscrapers, and people commuting by canoe.

All that and more has brought her here, to Transmissions, a 6,000-square-foot, immersive film installation that invites visitors to wander through windy coastal forests, by hauntingly empty glass towers, into soundscapes of ancient languages, and more.

Through the labyrinthine multimedia work at SFU [Simon Fraser University] Woodward’s, Jackson asks big questions—about Earth’s future, about humanity’s relationship to it, and about time and Indigeneity.

Simultaneously, she mashes up not just disciplines like film and sculpture, but concepts of science, storytelling, and linguistics [emphasis mine].

“The tag lines I’m working with now are ‘the roots of meaning’ and ‘knitting the world together’,” she explains. “In western society, we tend to hive things off into ‘That’s culture. That’s science.’ But from an Indigenous point of view, it’s all connected.”

Transmissions is split into three parts, with what Jackson describes as a beginning, a middle, and an end. Like Biidaaban, it’s also visually stunning: the artist admits she’s playing with Hollywood spectacle.

Without giving too much away—a big part of the appeal of Jackson’s work is the sense of surprise—Vancouver audiences will first enter a 48-foot-long, six-foot-wide tunnel, surrounded by projections that morph from empty urban streets to a forest and a river. Further engulfing them is a soundscape that features strong winds, while black mirrors along the floor skew perspective and play with what’s above and below ground.

“You feel out of time and space,” says Jackson, who wants to challenge western society’s linear notions of minutes and hours. “I want the audience to have a physical response and an emotional response. To me, that gets closer to the Indigenous understanding. Because the Eurocentric way is more rational, where the intellectual is put ahead of everything else.”

Viewers then enter a room, where the highly collaborative Jackson has worked with artist Alan Storey, who’s helped create Plexiglas towers that look like the ghost high-rises of an abandoned city. (Storey has also designed other components of the installation.) As audience members wander through them on foot, projections make their shadows dance on the structures. Like Biidaaban, the section hints at a postapocalyptic or posthuman world. Jackson operates in an emerging realm of Indigenous futurism.

The words “science, storytelling, and linguistics” were emphasized due to a minor problem I have with terminology. Linguistics is defined as the scientific study of language combining elements from the natural sciences, social sciences, and the humanities. I wish either Jackson or Smith had discussed the scientific element of Transmissions at more length and perhaps reconnected linguistics to science along with the physics of time and space, as well as, storytelling, film, and sculpture. It would have been helpful since it’s my understanding, Transmissions is designed to showcase all of those connections and more in ways that may not be obvious to everyone. On the plus side, perhaps the tour, which is part of this installation experience includes that information.

I have a bit .more detail (including logistics for the tours) from the SFU Events webpage for Transmissions,

TRANSMISSIONS is a three-part, 6000 square foot multimedia installation by award-winning Anishinaabe filmmaker and artist Lisa Jackson. It extends her investigation into the connections between land, language, and people, most recently with her virtual reality work Biidaaban: First Light.

Projections, sculpture, and film combine to create urban and natural landscapes that are eerie and beautiful, familiar and foreign, concrete and magical. Past and future collide in a visceral and thought-provoking journey that questions our current moment and opens up the complexity of thought systems embedded in Indigenous languages. Radically different from European languages, they embody sets of relationships to the land, to each other, and to time itself.

Transmissions invites us to untether from our day-to-day world and imagine a possible future. It provides a platform to activate and cross-pollinate knowledge systems, from science to storytelling, ecology to linguistics, art to commerce. To begin conversations, to listen deeply, to engage varied perspectives and expertise, to knit the world together and find our place within the circle of all our relations.

Her Story: Canadian Women Scientists (short film subjects); Sept. 13 – 14, 2019

Curiosity Collider, producer of art/science events in Vancouver, is presenting a film series featuring Canadian women scientists, according to an August 27 ,2019 press release (received via email),

Her Story: Canadian Women Scientists,” a film series dedicated to sharing the stories of Canadian women scientists, will premiere on September 13th and 14th at the Annex theatre. Four pairs of local filmmakers and Canadian women scientists collaborated to create 5-6 minute videos; for each film in the series, a scientist tells her own story, interwoven with the story of an inspiring Canadian women scientist who came before her in her field of study.

Produced by Vancouver-based non-profit organization Curiosity Collider, this project was developed to address the lack of storytelling videos showcasing remarkable women scientists and their work available via popular online platforms. “Her Story reveals the lives of women working in science,” said Larissa Blokhuis, curator for Her Story. “This project acts as a beacon to girls and women who want to see themselves in the scientific community. The intergenerational nature of the project highlights the fact that women have always worked in and contributed to science.

This sentiment was reflected by Samantha Baglot as well, a PhD student in neuroscience who collaborated with filmmaker/science cartoonist Armin Mortazavi in Her Story. “It is empowering to share stories of previous Canadian female scientists… it is empowering for myself as a current female scientist to learn about other stories of success, and gain perspective of how these women fought through various hardships and inequality.”

When asked why seeing better representation of women in scientific work is important, artist/filmmaker Michael Markowsky shared his thoughts. “It’s important for women — and their male allies — to question and push back against these perceived social norms, and to occupy space which rightfully belongs to them.” In fact, his wife just gave birth to their first child, a daughter; “It’s personally very important to me that she has strong female role models to look up to.” His film will feature collaborating scientist Jade Shiller, and Kathleen Conlan – who was named one of Canada’s greatest explorers by Canadian Geographic in 2015.

Other participating filmmakers and collaborating scientists include: Leslie Kennah (Filmmaker), Kimberly Girling (scientist, Research and Policy Director at Evidence for Democracy), Lucas Kavanagh and Jesse Lupini (Filmmakers, Avocado Video), and Jessica Pilarczyk (SFU Assistant Professor, Department of Earth Sciences).

This film series is supported by Westcoast Women in Engineering, Science and Technology (WWEST) and Eng.Cite. The venue for the events is provided by Vancouver Civic Theatres.

ETA September 4, 2019 at 1607 hours PDT: That last comment is even truer than I knew when I published earlier. I missed a Vancouver event, Maker Faire Vancouver will be hosted at Science World on Saturday, September 14. Here’s a little more about it from a Sept. 3, 2019 at Science World at Telus Science World blog posting,

Earlier last month [August 2019?], surgeons at St Paul’s Hospital performed an ankle replacement for a Cloverdale resident using a 3D printed bone. The first procedure of its kind in Western Canada, it saved the patient all of his ten toes — something doctors had originally decided to amputate due to the severity of the motorcycle accident.

Maker Faire Vancouver Co-producer, John Biehler, may not be using his 3D printer for medical breakthroughs, but he does see a subtle connection between his home 3D printer and the Health Canada-approved bone.

“I got into 3D printing to make fun stuff and gadgets,” John says of the box-sized machine that started as a hobby and turned into a side business. “But the fact that the very same technology can have life-changing and life-saving applications is amazing.”

When John showed up to Maker Faire Vancouver seven years ago, opportunities to access this hobby were limited. Armed with a 3D printer he had just finished assembling the night before, John was hoping to meet others in the community with similar interests to build, experiment and create. Much like the increase in accessibility to these portable machines has changed over the years—with universities, libraries and makerspaces making them readily available alongside CNC Machines, laser cutters and more — John says the excitement around crafting and tinkering has skyrocketed as well.

“The kind of technology that inspires people to print a bone or spinal insert all starts at ground zero in places like a Maker Faire where people get exposed to STEAM,” John says …

… From 3D printing enthusiasts like John to knitters, metal artists and roboticists, this full one-day event [Maker Faire Vancouver on Saturday, September 14, 2019] will facilitate cross-pollination between hobbyists, small businesses, artists and tinkerers. Described as part science fair, part county fair and part something entirely new, Maker Faire Vancouver hopes to facilitate discovery and what John calls “pure joy moments.”

Hopefully that’s it.

The latest and greatest in gene drives (for flies)

This is a CRISPR (clustered regularly interspaced short palindromic repeats) story where the researchers are working on flies. If successful, this has much wider implications. From an April 10, 2019 news item on phys.org,

New CRISPR-based gene drives and broader active genetics technologies are revolutionizing the way scientists engineer the transfer of specific traits from one generation to another.

Scientists at the University of California San Diego have now developed a new version of a gene drive that opens the door to the spread of specific, favorable subtle genetic variants, also known as “alleles,” throughout a population.

The new “allelic drive,” described April 9 [2019] in Nature Communications, is equipped with a guide RNA (gRNA) that directs the CRISPR system to cut undesired variants of a gene and replace it with a preferred version of the gene. The new drive extends scientists’ ability to modify populations of organisms with precision editing. Using word processing as an analogy, CRISPR-based gene drives allow scientists to edit sentences of genetic information, while the new allelic drive offers letter-by-letter editing.

An April 9, 2019 University of California at San Diego (UCSD) news release (also on EurekAlert) by Mario Aguilera, which originated the news item, delves into this technique’s potential uses while further explaining the work


In one example of its potential applications, specific genes in agricultural pests that have become resistant to insecticides could be replaced by original natural genetic variants conferring sensitivity to insecticides using allelic drives that selectively swap the identities of a single protein residue (amino acid).

In addition to agricultural applications, disease-carrying insects could be a target for allelic drives.

“If we incorporate such a normalizing gRNA on a gene-drive element, for example, one designed to immunize mosquitoes against malaria, the resulting allelic gene drive will spread through a population. When this dual action drive encounters an insecticide-resistant allele, it will cut and repair it using the wild-type susceptible allele,” said Ethan Bier, the new paper’s senior author. “The result being that nearly all emerging progeny will be sensitive to insecticides as well as refractory to malaria transmission.”

“Forcing these species to return to their natural sensitive state using allelic drives would help break a downward cycle of ever-increasing and environmentally damaging pesticide over-use,” said Annabel Guichard, the paper’s first author.

The researchers describe two versions of the allelic drive, including “copy-cutting,” in which researchers use the CRISPR system to selectively cut the undesired version of a gene, and a more broadly applicable version referred to as “copy-grafting” that promotes transmission of a favored allele next to the site that is selectively protected from gRNA cleavage.

“An unexpected finding from this study is that mistakes created by such allelic drives do not get transmitted to the next generation,” said Guichard. “These mutations instead produce an unusual form of lethality referred to as ‘lethal mosaicism.’ This process helps make allelic drives more efficient by immediately eliminating unwanted mutations created by CRISPR-based drives.”

Although demonstrated in fruit flies, the new technology also has potential for broad application in insects, mammals and plants. According to the researchers, several variations of the allelic drive technology could be developed with combinations of favorable traits in crops that, for example, thrive in poor soil and arid environments to help feed the ever-growing world population.

Beyond environmental applications, allelic drives should enable next-generation engineering of animal models to study human disease as well as answer important questions in basic science. As a member of the Tata Institute for Genetics and Society (TIGS), Bier says allelic drives could be used to aid in environmental conservation efforts to protect vulnerable endemic species or stop the spread of invasive species.

Gene drives and active genetics systems are now being developed for use in mammals. The scientists say allelic drives could accelerate new laboratory strains of animal models of human disease that aid in the development of new cures.

Here’s a link to and a citation for the paper,

Computers made of gold embroidery and an Organic Bioelectronics conference (ORBITALY) in Naples, Italy

Spend enough time reading about emerging technologies and, at some point, you will find yourself questioning some of your dearly held beliefs. It gives a whole new meaning to term, mind altering (also, mind blowing or mind expanding), which in the 1960s was used to refer to the effects of LSD and other hallucinogens. Today <September 1, 2019 (Labour Day in Canada and elsewhere), I have two news bits that could be considered mind expanding, sans hallucinogens.

Gold-embroidered computers

The Embroidered Computer. Artists: Irene Posch and Ebru Kurbak .[downloaded from http://www.ireneposch.net/the-embroidered-computer/]

If you look closely, you’ll see the beads shift position and that’s how the ones and zeroes make themselves known on this embroidered computer. An August 23, 2019 article (updated from a March 8, 2019 article) on the CBC’s (Canadian Broadcasting Corporation) Radio, Spark programme web space, provides insight into the work,

A beautiful ’embroidered computer’ may explode our categories of what computers are supposed to look like.

After all, we may think the design of a computer is permanent, but what a computer ‘looks like’ depends a lot on what era it’s from.

“We use gold-coloured copper wire to form a coil, in a donut shape” Posch told Spark host Nora Young. “Then we have a magnetic bead that sits in the middle of this coil, and when this coil is [connected to] power, the magnetic bead is either attracted or pushed away….

Depending on how we power… the embroidered coil, we can direct the magnetic bead in different positions.”

More gold embroidery on top of the bead will flip one way or another, based on the bead [above].

The process is analogous to the zeros and ones of computation.

As well as being an artist, Posch is a professor at the University for Art and Industrial Design in Linz, Austria. Much of her work and research uses textile art to explore digital technology.

In this case, it’s not like Irene expects people to start doing today’s heavy-duty computing on a two-metre-long, eight-bit golden embroidered fabric computer. But The Embroidered Computer project opens up space to question the design of computers in particular, but also our technologies in general

“I understand The Embroidered Computer as an alternative, as an example, but also a critique of what we assume a computer to be today, and how it technically could be different,” Posch said. “If this is actually what we want is a whole different question, but I think it’s interesting to propose an alternative.”

Bringing together textiles and electronics, which are normally seen as worlds apart, can bring new insights. “Going into the history of computing we very soon become aware that they’re not that apart as we sometimes think they are, if you think of the Jacquard weaving loom as one of the predecessors of computing today.”

ORBITALY 2019

I don’t have a lot of information about this event but what I do have looks intriguing. From the ORBITALY 2019 conference home page,

OrBItaly (Organic BIoelectronics Italy) is an international conference, organized by the Italian Scientific Community and attended by scientists of the highest reputation, dedicated to the most recent results in the field of bioelectronics, with a particular focus on the employment of organic materials.

OrBItaly has attracted in the years a growing interest by scientists coming from all over the world. The 2019 edition is the fifth one of this cross-disciplinary conference, and will be held in Naples, on October 21st-23rd, 2019, at the Congress Center of the University Federico II

This year the conference will be preceded by the first edition of the Graduate School in Organic Bioelectronics, that will be held at the Congress Center of the University of Naples Federico II in Naples (Italy), on October 20th, 2019. The school is mainly targeted to PhD students, post-docs and young researchers as well as to senior scientists and industry-oriented researchers, giving them the opportunity to attend an overview of the latest advances in the fields of organic bioelectronics presented by leading scientists of the highest international repute. Invited lecturers will provide highly stimulating lessons at advanced levels in their own field of research, and closely interact with the attendees during platform discussions, outreach events and informal meetings.

AI (artificial intelligence) artist got a show at a New York City art gallery

AI artists first hit my radar in August 2018 when Christie’s Auction House advertised an art auction of a ‘painting’ by an algorithm (artificial intelligence). There’s more in my August 31, 2018 posting but, briefly, a French art collective, Obvious, submitted a painting, “Portrait of Edmond de Belamy,” that was created by an artificial intelligence agent to be sold for an estimated to $7000 – $10,000. They weren’t even close. According to Ian Bogost’s March 6, 2019 article for The Atlantic, the painting sold for $432,500 In October 2018.

It has also, Bogost notes in his article, occasioned an art show (Note: Links have been removed),

… part of “Faceless Portraits Transcending Time,” an exhibition of prints recently shown [Februay 13 – March 5, 2019] at the HG Contemporary gallery in Chelsea, the epicenter of New York’s contemporary-art world. All of them were created by a computer.

The catalog calls the show a “collaboration between an artificial intelligence named AICAN and its creator, Dr. Ahmed Elgammal,” a move meant to spotlight, and anthropomorphize, the machine-learning algorithm that did most of the work. According to HG Contemporary, it’s the first solo gallery exhibit devoted to an AI artist.

If they hadn’t found each other in the New York art scene, the players involved could have met on a Spike Jonze film set: a computer scientist commanding five-figure print sales from software that generates inkjet-printed images; a former hotel-chain financial analyst turned Chelsea techno-gallerist with apparent ties to fine-arts nobility; a venture capitalist with two doctoral degrees in biomedical informatics; and an art consultant who put the whole thing together, A-Team–style, after a chance encounter at a blockchain conference. Together, they hope to reinvent visual art, or at least to cash in on machine-learning hype along the way.

The show in New York City, “Faceless Portraits …,” exhibited work by an artificially intelligent artist-agent (I’m creating a new term to suit my purposes) that’s different than the one used by Obvious to create “Portrait of Edmond de Belamy,” As noted earlier, it sold for a lot of money (Note: Links have been removed),

Bystanders in and out of the art world were shocked. The print had never been shown in galleries or exhibitions before coming to market at auction, a channel usually reserved for established work. The winning bid was made anonymously by telephone, raising some eyebrows; art auctions can invite price manipulation. It was created by a computer program that generates new images based on patterns in a body of existing work, whose features the AI “learns.” What’s more, the artists who trained and generated the work, the French collective Obvious, hadn’t even written the algorithm or the training set. They just downloaded them, made some tweaks, and sent the results to market.

“We are the people who decided to do this,” the Obvious member Pierre Fautrel said in response to the criticism, “who decided to print it on canvas, sign it as a mathematical formula, put it in a gold frame.” A century after Marcel Duchamp made a urinal into art [emphasis mine] by putting it in a gallery, not much has changed, with or without computers. As Andy Warhol famously said, “Art is what you can get away with.”

A bit of a segue here, there is a controversy as to whether or not that ‘urinal art’, also known as, The Fountain, should be attributed to Duchamp as noted in my January 23, 2019 posting titled ‘Baroness Elsa von Freytag-Loringhoven, Marcel Duchamp, and the Fountain’.

Getting back to the main action, Bogost goes on to describe the technologies underlying the two different AI artist-agents (Note: Links have been removed),

… Using a computer is hardly enough anymore; today’s machines offer all kinds of ways to generate images that can be output, framed, displayed, and sold—from digital photography to artificial intelligence. Recently, the fashionable choice has become generative adversarial networks, or GANs, the technology that created Portrait of Edmond de Belamy. Like other machine-learning methods, GANs use a sample set—in this case, art, or at least images of it—to deduce patterns, and then they use that knowledge to create new pieces. A typical Renaissance portrait, for example, might be composed as a bust or three-quarter view of a subject. The computer may have no idea what a bust is, but if it sees enough of them, it might learn the pattern and try to replicate it in an image.

GANs use two neural nets (a way of processing information modeled after the human brain) to produce images: a “generator” and a “discerner.” The generator produces new outputs—images, in the case of visual art—and the discerner tests them against the training set to make sure they comply with whatever patterns the computer has gleaned from that data. The quality or usefulness of the results depends largely on having a well-trained system, which is difficult.

That’s why folks in the know were upset by the Edmond de Belamy auction. The image was created by an algorithm the artists didn’t write, trained on an “Old Masters” image set they also didn’t create. The art world is no stranger to trend and bluster driving attention, but the brave new world of AI painting appeared to be just more found art, the machine-learning equivalent of a urinal on a plinth.

Ahmed Elgammal thinks AI art can be much more than that. A Rutgers University professor of computer science, Elgammal runs an art-and-artificial-intelligence lab, where he and his colleagues develop technologies that try to understand and generate new “art” (the scare quotes are Elgammal’s) with AI—not just credible copies of existing work, like GANs do. “That’s not art, that’s just repainting,” Elgammal says of GAN-made images. “It’s what a bad artist would do.”

Elgammal calls his approach a “creative adversarial network,” or CAN. It swaps a GAN’s discerner—the part that ensures similarity—for one that introduces novelty instead. The system amounts to a theory of how art evolves: through small alterations to a known style that produce a new one. That’s a convenient take, given that any machine-learning technique has to base its work on a specific training set.

The results are striking and strange, although calling them a new artistic style might be a stretch. They’re more like credible takes on visual abstraction. The images in the show, which were produced based on training sets of Renaissance portraits and skulls, are more figurative, and fairly disturbing. Their gallery placards name them dukes, earls, queens, and the like, although they depict no actual people—instead, human-like figures, their features smeared and contorted yet still legible as portraiture. Faceless Portrait of a Merchant, for example, depicts a torso that might also read as the front legs and rear haunches of a hound. Atop it, a fleshy orb comes across as a head. The whole scene is rippled by the machine-learning algorithm, in the way of so many computer-generated artworks.

Bogost consults an expert on portraiture for a discussion about the particularities of portraiture and the shortcomings one might expect of an AI artist-agent (Note: A link has been removed),

“You can’t really pick a form of painting that’s more charged with cultural meaning than portraiture,” John Sharp, an art historian trained in 15th-century Italian painting and the director of the M.F.A. program in design and technology at Parsons School of Design, told me. The portrait isn’t just a style, it’s also a host for symbolism. “For example, men might be shown with an open book to show how they are in dialogue with that material; or a writing implement, to suggest authority; or a weapon, to evince power.” Take Portrait of a Youth Holding an Arrow, an early-16th-century Boltraffio portrait that helped train the AICAN database for the show. The painting depicts a young man, believed to be the Bolognese poet Girolamo Casio, holding an arrow at an angle in his fingers and across his chest. It doubles as both weapon and quill, a potent symbol of poetry and aristocracy alike. Along with the arrow, the laurels in Casio’s hair are emblems of Apollo, the god of both poetry and archery.

A neural net couldn’t infer anything about the particular symbolic trappings of the Renaissance or antiquity—unless it was taught to, and that wouldn’t happen just by showing it lots of portraits. For Sharp and other critics of computer-generated art, the result betrays an unforgivable ignorance about the supposed influence of the source material.

But for the purposes of the show, the appeal to the Renaissance might be mostly a foil, a way to yoke a hip, new technology to traditional painting in order to imbue it with the gravity of history: not only a Chelsea gallery show, but also an homage to the portraiture found at the Met. To reinforce a connection to the cradle of European art, some of the images are presented in elaborate frames, a decision the gallerist, Philippe Hoerle-Guggenheim (yes, that Guggenheim; he says the relation is “distant”) [the Guggenheim is strongly associated with the visual arts by way the two Guggeheim museums, one in New York City and the other in Bilbao, Portugal], told me he insisted upon. Meanwhile, the technical method makes its way onto the gallery placards in an official-sounding way—“Creative Adversarial Network print.” But both sets of inspirations, machine-learning and Renaissance portraiture, get limited billing and zero explanation at the show. That was deliberate, Hoerle-Guggenheim said. He’s betting that the simple existence of a visually arresting AI painting will be enough to draw interest—and buyers. It would turn out to be a good bet.

The art market is just that: a market. Some of the most renowned names in art today, from Damien Hirst to Banksy, trade in the trade of art as much as—and perhaps even more than—in the production of images, objects, and aesthetics. No artist today can avoid entering that fray, Elgammal included. “Is he an artist?” Hoerle-Guggenheim asked himself of the computer scientist. “Now that he’s in this context, he must be.” But is that enough? In Sharp’s estimation, “Faceless Portraits Transcending Time” is a tech demo more than a deliberate oeuvre, even compared to the machine-learning-driven work of his design-and-technology M.F.A. students, who self-identify as artists first.

Judged as Banksy or Hirst might be, Elgammal’s most art-worthy work might be the Artrendex start-up itself, not the pigment-print portraits that its technology has output. Elgammal doesn’t treat his commercial venture like a secret, but he also doesn’t surface it as a beneficiary of his supposedly earnest solo gallery show. He’s argued that AI-made images constitute a kind of conceptual art, but conceptualists tend to privilege process over product or to make the process as visible as the product.

Hoerle-Guggenheim worked as a financial analyst for Hyatt before getting into the art business via some kind of consulting deal (he responded cryptically when I pressed him for details). …

This is a fascinating article and I have one last excerpt, which poses this question, is an AI artist-agent a collaborator or a medium? There ‘s also speculation about how AI artist-agents might impact the business of art (Note: Links have been removed),

… it’s odd to list AICAN as a collaborator—painters credit pigment as a medium, not as a partner. Even the most committed digital artists don’t present the tools of their own inventions that way; when they do, it’s only after years, or even decades, of ongoing use and refinement.

But Elgammal insists that the move is justified because the machine produces unexpected results. “A camera is a tool—a mechanical device—but it’s not creative,” he said. “Using a tool is an unfair term for AICAN. It’s the first time in history that a tool has had some kind of creativity, that it can surprise you.” Casey Reas, a digital artist who co-designed the popular visual-arts-oriented coding platform Processing, which he uses to create some of his fine art, isn’t convinced. “The artist should claim responsibility over the work rather than to cede that agency to the tool or the system they create,” he told me.

Elgammal’s financial interest in AICAN might explain his insistence on foregrounding its role. Unlike a specialized print-making technique or even the Processing coding environment, AICAN isn’t just a device that Elgammal created. It’s also a commercial enterprise.

Elgammal has already spun off a company, Artrendex, that provides “artificial-intelligence innovations for the art market.” One of them offers provenance authentication for artworks; another can suggest works a viewer or collector might appreciate based on an existing collection; another, a system for cataloging images by visual properties and not just by metadata, has been licensed by the Barnes Foundation to drive its collection-browsing website.

The company’s plans are more ambitious than recommendations and fancy online catalogs. When presenting on a panel about the uses of blockchain for managing art sales and provenance, Elgammal caught the attention of Jessica Davidson, an art consultant who advises artists and galleries in building collections and exhibits. Davidson had been looking for business-development partnerships, and she became intrigued by AICAN as a marketable product. “I was interested in how we can harness it in a compelling way,” she says.

The art market is just that: a market. Some of the most renowned names in art today, from Damien Hirst to Banksy, trade in the trade of art as much as—and perhaps even more than—in the production of images, objects, and aesthetics. No artist today can avoid entering that fray, Elgammal included. “Is he an artist?” Hoerle-Guggenheim asked himself of the computer scientist. “Now that he’s in this context, he must be.” But is that enough? In Sharp’s estimation, “Faceless Portraits Transcending Time” is a tech demo more than a deliberate oeuvre, even compared to the machine-learning-driven work of his design-and-technology M.F.A. students, who self-identify as artists first.

Judged as Banksy or Hirst might be, Elgammal’s most art-worthy work might be the Artrendex start-up itself, not the pigment-print portraits that its technology has output. Elgammal doesn’t treat his commercial venture like a secret, but he also doesn’t surface it as a beneficiary of his supposedly earnest solo gallery show. He’s argued that AI-made images constitute a kind of conceptual art, but conceptualists tend to privilege process over product or to make the process as visible as the product.

Hoerle-Guggenheim worked as a financial analyst[emphasis mine] for Hyatt before getting into the art business via some kind of consulting deal (he responded cryptically when I pressed him for details). …

If you have the time, I recommend reading Bogost’s March 6, 2019 article for The Atlantic in its entirety/ these excerpts don’t do it enough justice.

Portraiture: what does it mean these days?

After reading the article I have a few questions. What exactly do Bogost and the arty types in the article mean by the word ‘portrait’? “Portrait of Edmond de Belamy” is an image of someone who doesn’t and never has existed and the exhibit “Faceless Portraits Transcending Time,” features images that don’t bear much or, in some cases, any resemblance to human beings. Maybe this is considered a dull question by people in the know but I’m an outsider and I found the paradox: portraits of nonexistent people or nonpeople kind of interesting.

BTW, I double-checked my assumption about portraits and found this definition in the Portrait Wikipedia entry (Note: Links have been removed),

A portrait is a painting, photograph, sculpture, or other artistic representation of a person [emphasis mine], in which the face and its expression is predominant. The intent is to display the likeness, personality, and even the mood of the person. For this reason, in photography a portrait is generally not a snapshot, but a composed image of a person in a still position. A portrait often shows a person looking directly at the painter or photographer, in order to most successfully engage the subject with the viewer.

So, portraits that aren’t portraits give rise to some philosophical questions but Bogost either didn’t want to jump into that rabbit hole (segue into yet another topic) or, as I hinted earlier, may have assumed his audience had previous experience of those kinds of discussions.

Vancouver (Canada) and a ‘portraiture’ exhibit at the Rennie Museum

By one of life’s coincidences, Vancouver’s Rennie Museum had an exhibit (February 16 – June 15, 2019) that illuminates questions about art collecting and portraiture, From a February 7, 2019 Rennie Museum news release,

Press Release | Spring 2019: Collected Works
By rennie museum

rennie museum is pleased to present Spring 2019: Collected Works, a group exhibition encompassing the mediums of photography, painting and film. A portraiture of the collecting spirit [emphasis mine], the works exhibited invite exploration of what collected objects, and both the considered and unintentional ways they are displayed, inform us. Featuring the works of four artists—Andrew Grassie, William E. Jones, Louise Lawler and Catherine Opie—the exhibition runs from February 16 to June 15, 2019.

Four exquisite paintings by Scottish painter Andrew Grassie detailing the home and private storage space of a major art collector provide a peek at how the passionately devoted integrates and accommodates the physical embodiments of such commitment into daily life. Grassie’s carefully constructed, hyper-realistic images also pose the question, “What happens to art once it’s sold?” In the transition from pristine gallery setting to idiosyncratic private space, how does the new context infuse our reading of the art and how does the art shift our perception of the individual?

Furthering the inquiry into the symbiotic exchange between possessor and possession, a selection of images by American photographer Louise Lawler depicting art installed in various private and public settings question how the bilateral relationship permeates our interpretation when the collector and the collected are no longer immediately connected. What does de-acquisitioning an object inform us and how does provenance affect our consideration of the art?

The question of legacy became an unexpected facet of 700 Nimes Road (2010-2011), American photographer Catherine Opie’s portrait of legendary actress Elizabeth Taylor. Opie did not directly photograph Taylor for any of the fifty images in the expansive portfolio. Instead, she focused on Taylor’s home and the objects within, inviting viewers to see—then see beyond—the façade of fame and consider how both treasures and trinkets act as vignettes to the stories of a life. Glamorous images of jewels and trophies juxtapose with mundane shots of a printer and the remote-control user manual. Groupings of major artworks on the wall are as illuminating of the home’s mistress as clusters of personal photos. Taylor passed away part way through Opie’s project. The subsequent photos include Taylor’s mementos heading off to auction, raising the question, “Once the collections that help to define someone are disbursed, will our image of that person lose focus?”

In a similar fashion, the twenty-two photographs in Villa Iolas (1982/2017), by American artist and filmmaker William E. Jones, depict the Athens home of iconic art dealer and collector Alexander Iolas. Taken in 1982 by Jones during his first travels abroad, the photographs of art, furniture and antiquities tell a story of privilege that contrast sharply with the images Jones captures on a return visit in 2016. Nearly three decades after Iolas’s 1989 death, his home sits in dilapidation, looted and vandalized. Iolas played an extraordinary role in the evolution of modern art, building the careers of Max Ernst, Yves Klein and Giorgio de Chirico. He gave Andy Warhol his first solo exhibition and was a key advisor to famed collectors John and Dominique de Menil. Yet in the years since his death, his intention of turning his home into a modern art museum as a gift to Greece, along with his reputation, crumbled into ruins. The photographs taken by Jones during his visits in two different eras are incorporated into the film Fall into Ruin (2017), along with shots of contemporary Athens and antiquities on display at the National Archaeological Museum.

“I ask a lot of questions about how portraiture functionswhat is there to describe the person or time we live in or a certain set of politics…”
 – Catherine Opie, The Guardian, Feb 9, 2016

We tend to think of the act of collecting as a formal activity yet it can happen casually on a daily basis, often in trivial ways. While we readily acknowledge a collector consciously assembling with deliberate thought, we give lesser consideration to the arbitrary accumulations that each of us accrue. Be it master artworks, incidental baubles or random curios, the objects we acquire and surround ourselves with tell stories of who we are.

Andrew Grassie (Scotland, b. 1966) is a painter known for his small scale, hyper-realist works. He has been the subject of solo exhibitions at the Tate Britain; Talbot Rice Gallery, Edinburgh; institut supérieur des arts de Toulouse; and rennie museum, Vancouver, Canada. He lives and works in London, England.

William E. Jones (USA, b. 1962) is an artist, experimental film-essayist and writer. Jones’s work has been the subject of retrospectives at Tate Modern, London; Anthology Film Archives, New York; Austrian Film Museum, Vienna; and, Oberhausen Short Film Festival. He is a recipient of the John Simon Guggenheim Memorial Fellowship and the Creative Capital/Andy Warhol Foundation Arts Writers Grant. He lives and works in Los Angeles, USA.

Louise Lawler (USA, b. 1947) is a photographer and one of the foremost members of the Pictures Generation. Lawler was the subject of a major retrospective at the Museum of Modern Art, New York in 2017. She has held exhibitions at the Whitney Museum of American Art, New York; Stedelijk Museum, Amsterdam; National Museum of Art, Oslo; and Musée d’Art Moderne de La Ville de Paris. She lives and works in New York.

Catherine Opie (USA, b. 1961) is a photographer and educator. Her work has been exhibited at Wexner Center for the Arts, Ohio; Henie Onstad Art Center, Oslo; Los the Angeles County Museum of Art; Portland Art Museum; and the Guggenheim Museum, New York. She is the recipient of United States Artist Fellowship, Julius Shulman’s Excellence in Photography Award, and the Smithsonian’s Archive of American Art Medal.  She lives and works in Los Angeles.

rennie museum opened in October 2009 in historic Wing Sang, the oldest structure in Vancouver’s Chinatown, to feature dynamic exhibitions comprising only of art drawn from rennie collection. Showcasing works by emerging and established international artists, the exhibits, accompanied by supporting catalogues, are open free to the public through engaging guided tours. The museum’s commitment to providing access to arts and culture is also expressed through its education program, which offers free age-appropriate tours and customized workshops to children of all ages.

rennie collection is a globally recognized collection of contemporary art that focuses on works that tackle issues related to identity, social commentary and injustice, appropriation, and the nature of painting, photography, sculpture and film. Currently the collection includes works by over 370 emerging and established artists, with over fifty collected in depth. The Vancouver based collection engages actively with numerous museums globally through a robust, artist-centric, lending policy.

So despite the Wikipedia definition, it seems that portraits don’t always feature people. While Bogost didn’t jump into that particular rabbit hole, he did touch on the business side of art.

What about intellectual property?

Bogost doesn’t explicitly discuss this particular issue. It’s a big topic so I’m touching on it only lightly, if an artist worsk with an AI, the question as to ownership of the artwork could prove thorny. Is the copyright owner the computer scientist or the artist or both? Or does the AI artist-agent itself own the copyright? That last question may not be all that farfetched. Sophia, a social humanoid robot, has occasioned thought about ‘personhood.’ (Note: The robots mentioned in this posting have artificial intelligence.) From the Sophia (robot) Wikipedia entry (Note: Links have been removed),

Sophia has been interviewed in the same manner as a human, striking up conversations with hosts. Some replies have been nonsensical, while others have impressed interviewers such as 60 Minutes’ Charlie Rose.[12] In a piece for CNBC, when the interviewer expressed concerns about robot behavior, Sophia joked that he had “been reading too much Elon Musk. And watching too many Hollywood movies”.[27] Musk tweeted that Sophia should watch The Godfather and asked “what’s the worst that could happen?”[28][29] Business Insider’s chief UK editor Jim Edwards interviewed Sophia, and while the answers were “not altogether terrible”, he predicted it was a step towards “conversational artificial intelligence”.[30] At the 2018 Consumer Electronics Show, a BBC News reporter described talking with Sophia as “a slightly awkward experience”.[31]

On October 11, 2017, Sophia was introduced to the United Nations with a brief conversation with the United Nations Deputy Secretary-General, Amina J. Mohammed.[32] On October 25, at the Future Investment Summit in Riyadh, the robot was granted Saudi Arabian citizenship [emphasis mine], becoming the first robot ever to have a nationality.[29][33] This attracted controversy as some commentators wondered if this implied that Sophia could vote or marry, or whether a deliberate system shutdown could be considered murder. Social media users used Sophia’s citizenship to criticize Saudi Arabia’s human rights record. In December 2017, Sophia’s creator David Hanson said in an interview that Sophia would use her citizenship to advocate for women’s rights in her new country of citizenship; Newsweek criticized that “What [Hanson] means, exactly, is unclear”.[34] On November 27, 2018 Sophia was given a visa by Azerbaijan while attending Global Influencer Day Congress held in Baku. December 15, 2018 Sophia was appointed a Belt and Road Innovative Technology Ambassador by China'[35]

As for an AI artist-agent’s intellectual property rights , I have a July 10, 2017 posting featuring that question in more detail. Whether you read that piece or not, it seems obvious that artists might hesitate to call an AI agent, a partner rather than a medium of expression. After all, a partner (and/or the computer scientist who developed the programme) might expect to share in property rights and profits but paint, marble, plastic, and other media used by artists don’t have those expectations.

Moving slightly off topic , in my July 10, 2017 posting I mentioned a competition (literary and performing arts rather than visual arts) called, ‘Dartmouth College and its Neukom Institute Prizes in Computational Arts’. It was started in 2016 and, as of 2018, was still operational under this name: Creative Turing Tests. Assuming there’ll be contests for prizes in 2019, there’s (from the contest site) [1] PoetiX, competition in computer-generated sonnet writing; [2] Musical Style, composition algorithms in various styles, and human-machine improvisation …; and [3] DigiLit, algorithms able to produce “human-level” short story writing that is indistinguishable from an “average” human effort. You can find the contest site here.

Audio map of 24 emotions

The real map, not the the image of the map you see above, offers a disconcerting (for me, anyway) experience. Especially since I’ve just finished reading Lisa Feldman Barrett’s 2017 book, How Emotions are Made, where she presents her theory of ‘constructed emotion. (There’s more about ‘constructed emotion’ later in this post.)

Moving on to the story about the ‘auditory emotion map’ in the headline, a February 4, 2019 University of California at Berkeley news release by Yasmin Anwar (also on EurekAlert but published on Feb. 5, 2019) describes the work,

Ooh, surprise! Those spontaneous sounds we make to express everything from elation (woohoo) to embarrassment (oops) say a lot more about what we’re feeling than previously understood, according to new research from the University of California, Berkeley.

Proving that a sigh is not just a sigh [a reference to the song, As Time Goes By? The lyric is “a kiss is still a kiss, a sigh is just a sigh …”], UC Berkeley scientists conducted a statistical analysis of listener responses to more than 2,000 nonverbal exclamations known as “vocal bursts” and found they convey at least 24 kinds of emotion. Previous studies of vocal bursts set the number of recognizable emotions closer to 13.

The results, recently published online in the American Psychologist journal, are demonstrated in vivid sound and color on the first-ever interactive audio map of nonverbal vocal communication.

“This study is the most extensive demonstration of our rich emotional vocal repertoire, involving brief signals of upwards of two dozen emotions as intriguing as awe, adoration, interest, sympathy and embarrassment,” said study senior author Dacher Keltner, a psychology professor at UC Berkeley and faculty director of the Greater Good Science Center, which helped support the research.

For millions of years, humans have used wordless vocalizations to communicate feelings that can be decoded in a matter of seconds, as this latest study demonstrates.

“Our findings show that the voice is a much more powerful tool for expressing emotion than previously assumed,” said study lead author Alan Cowen, a Ph.D. student in psychology at UC Berkeley.

On Cowen’s audio map, one can slide one’s cursor across the emotional topography and hover over fear (scream), then surprise (gasp), then awe (woah), realization (ohhh), interest (ah?) and finally confusion (huh?).

Among other applications, the map can be used to help teach voice-controlled digital assistants and other robotic devices to better recognize human emotions based on the sounds we make, he said.

As for clinical uses, the map could theoretically guide medical professionals and researchers working with people with dementia, autism and other emotional processing disorders to zero in on specific emotion-related deficits.

“It lays out the different vocal emotions that someone with a disorder might have difficulty understanding,” Cowen said. “For example, you might want to sample the sounds to see if the patient is recognizing nuanced differences between, say, awe and confusion.”

Though limited to U.S. responses, the study suggests humans are so keenly attuned to nonverbal signals – such as the bonding “coos” between parents and infants – that we can pick up on the subtle differences between surprise and alarm, or an amused laugh versus an embarrassed laugh.

For example, by placing the cursor in the embarrassment region of the map, you might find a vocalization that is recognized as a mix of amusement, embarrassment and positive surprise.

A tour through amusement reveals the rich vocabulary of laughter and a spin through the sounds of adoration, sympathy, ecstasy and desire may tell you more about romantic life than you might expect,” said Keltner.

Researchers recorded more than 2,000 vocal bursts from 56 male and female professional actors and non-actors from the United States, India, Kenya and Singapore by asking them to respond to emotionally evocative scenarios.

Next, more than 1,000 adults recruited via Amazon’s Mechanical Turk online marketplace listened to the vocal bursts and evaluated them based on the emotions and meaning they conveyed and whether the tone was positive or negative, among several other characteristics.

A statistical analysis of their responses found that the vocal bursts fit into at least two dozen distinct categories including amusement, anger, awe, confusion, contempt, contentment, desire, disappointment, disgust, distress, ecstasy, elation, embarrassment, fear, interest, pain, realization, relief, sadness, surprise (positive) surprise (negative), sympathy and triumph.

For the second part of the study, researchers sought to present real-world contexts for the vocal bursts. They did this by sampling YouTube video clips that would evoke the 24 emotions established in the first part of the study, such as babies falling, puppies being hugged and spellbinding magic tricks.

This time, 88 adults of all ages judged the vocal bursts extracted from YouTube videos. Again, the researchers were able to categorize their responses into 24 shades of emotion. The full set of data were then organized into a semantic space onto an interactive map.

“These results show that emotional expressions color our social interactions with spirited declarations of our inner feelings that are difficult to fake, and that our friends, co-workers, and loved ones rely on to decipher our true commitments,” Cowen said.

The writer assumes that emotions are pre-existing. Somewhere, there’s happiness, sadness, anger, etc. It’s the pre-existence that Lisa Feldman Barret challenges with her theory that we construct our emotions (from her Wikipedia entry),

She highlights differences in emotions between different cultures, and says that emotions “are not triggered; you create them. They emerge as a combination of the physical properties of your body, a flexible brain that wires itself to whatever environment it develops in, and your culture and upbringing, which provide that environment.”

You can find Barrett’s December 6, 2017 TED talk here wheres she explains her theory in greater detail. One final note about Barrett, she was born and educated in Canada and now works as a Professor of Psychology at Northeastern University, with appointments at Harvard Medical School and Massachusetts General Hospital at Northeastern University in Boston, Massachusetts; US.

A February 7, 2019 by Mark Wilson for Fast Company delves further into the 24 emotion audio map mentioned at the outset of this posting (Note: Links have been removed),

Fear, surprise, awe. Desire, ecstasy, relief.

These emotions are not distinct, but interconnected, across the gradient of human experience. At least that’s what a new paper from researchers at the University of California, Berkeley, Washington University, and Stockholm University proposes. The accompanying interactive map, which charts the sounds we make and how we feel about them, will likely persuade you to agree.

At the end of his article, Wilson also mentions the Dalai Lama and his Atlas of Emotions, a data visualization project, (featured in Mark Wilson’s May 13, 2016 article for Fast Company). It seems humans of all stripes are interested in emotions.

Here’s a link to and a citation for the paper about the audio map,
