How might artificial intelligence affect urban life in 2030? A study

Peering into the future is always a chancy business as anyone who’s seen those film shorts from the 1950’s and 60’s which speculate exuberantly as to what the future will bring knows.

A sober approach (appropriate to our times) has been taken in a study about the impact that artificial intelligence might have by 2030. From a Sept. 1, 2016 Stanford University news release (also on EurekAlert) by Tom Abate (Note: Links have been removed),

A panel of academic and industrial thinkers has looked ahead to 2030 to forecast how advances in artificial intelligence (AI) might affect life in a typical North American city – in areas as diverse as transportation, health care and education ­– and to spur discussion about how to ensure the safe, fair and beneficial development of these rapidly emerging technologies.

Titled “Artificial Intelligence and Life in 2030,” this year-long investigation is the first product of the One Hundred Year Study on Artificial Intelligence (AI100), an ongoing project hosted by Stanford to inform societal deliberation and provide guidance on the ethical development of smart software, sensors and machines.

“We believe specialized AI applications will become both increasingly common and more useful by 2030, improving our economy and quality of life,” said Peter Stone, a computer scientist at the University of Texas at Austin and chair of the 17-member panel of international experts. “But this technology will also create profound challenges, affecting jobs and incomes and other issues that we should begin addressing now to ensure that the benefits of AI are broadly shared.”

The new report traces its roots to a 2009 study that brought AI scientists together in a process of introspection that became ongoing in 2014, when Eric and Mary Horvitz created the AI100 endowment through Stanford. AI100 formed a standing committee of scientists and charged this body with commissioning periodic reports on different aspects of AI over the ensuing century.

“This process will be a marathon, not a sprint, but today we’ve made a good start,” said Russ Altman, a professor of bioengineering and the Stanford faculty director of AI100. “Stanford is excited to host this process of introspection. This work makes practical contribution to the public debate on the roles and implications of artificial intelligence.”

The AI100 standing committee first met in 2015, led by chairwoman and Harvard computer scientist Barbara Grosz. It sought to convene a panel of scientists with diverse professional and personal backgrounds and enlist their expertise to assess the technological, economic and policy implications of potential AI applications in a societally relevant setting.

“AI technologies can be reliable and broadly beneficial,” Grosz said. “Being transparent about their design and deployment challenges will build trust and avert unjustified fear and suspicion.”

The report investigates eight domains of human activity in which AI technologies are beginning to affect urban life in ways that will become increasingly pervasive and profound by 2030.

The 28,000-word report includes a glossary to help nontechnical readers understand how AI applications such as computer vision might help screen tissue samples for cancers or how natural language processing will allow computerized systems to grasp not simply the literal definitions, but the connotations and intent, behind words.

The report is broken into eight sections focusing on applications of AI. Five examine application arenas such as transportation where there is already buzz about self-driving cars. Three other sections treat technological impacts, like the section on employment and workplace trends which touches on the likelihood of rapid changes in jobs and incomes.

“It is not too soon for social debate on how the fruits of an AI-dominated economy should be shared,” the researchers write in the report, noting also the need for public discourse.

“Currently in the United States, at least sixteen separate agencies govern sectors of the economy related to AI technologies,” the researchers write, highlighting issues raised by AI applications: “Who is responsible when a self-driven car crashes or an intelligent medical device fails? How can AI applications be prevented from [being used for] racial discrimination or financial cheating?”

The eight sections discuss:

Transportation: Autonomous cars, trucks and, possibly, aerial delivery vehicles may alter how we commute, work and shop and create new patterns of life and leisure in cities.

Home/service robots: Like the robotic vacuum cleaners already in some homes, specialized robots will clean and provide security in live/work spaces that will be equipped with sensors and remote controls.

Health care: Devices to monitor personal health and robot-assisted surgery are hints of things to come if AI is developed in ways that gain the trust of doctors, nurses, patients and regulators.

Education: Interactive tutoring systems already help students learn languages, math and other skills. More is possible if technologies like natural language processing platforms develop to augment instruction by humans.

Entertainment: The conjunction of content creation tools, social networks and AI will lead to new ways to gather, organize and deliver media in engaging, personalized and interactive ways.

Low-resource communities: Investments in uplifting technologies like predictive models to prevent lead poisoning or improve food distributions could spread AI benefits to the underserved.

Public safety and security: Cameras, drones and software to analyze crime patterns should use AI in ways that reduce human bias and enhance safety without loss of liberty or dignity.

Employment and workplace: Work should start now on how to help people adapt as the economy undergoes rapid changes as many existing jobs are lost and new ones are created.

“Until now, most of what is known about AI comes from science fiction books and movies,” Stone said. “This study provides a realistic foundation to discuss how AI technologies are likely to affect society.”

Grosz said she hopes the AI 100 report “initiates a century-long conversation about ways AI-enhanced technologies might be shaped to improve life and societies.”

The AI100 website’s About page offered a surprise,

This effort, called the One Hundred Year Study on Artificial Intelligence, or AI100, is the brainchild of computer scientist and Stanford alumnus Eric Horvitz who, among other credits, is a former president of the Association for the Advancement of Artificial Intelligence.

In that capacity Horvitz convened a conference in 2009 at which top researchers considered advances in artificial intelligence and its influences on people and society, a discussion that illuminated the need for continuing study of AI’s long-term implications.

Now, together with Russ Altman, a professor of bioengineering and computer science at Stanford, Horvitz has formed a committee that will select a panel to begin a series of periodic studies on how AI will affect automation, national security, psychology, ethics, law, privacy, democracy and other issues.

“Artificial intelligence is one of the most profound undertakings in science, and one that will affect every aspect of human life,” said Stanford President John Hennessy, who helped initiate the project. “Given’s Stanford’s pioneering role in AI and our interdisciplinary mindset, we feel obliged and qualified to host a conversation about how artificial intelligence will affect our children and our children’s children.”

Five leading academicians with diverse interests will join Horvitz and Altman in launching this effort. They are:

  • Barbara Grosz, the Higgins Professor of Natural Sciences at HarvardUniversity and an expert on multi-agent collaborative systems;
  • Deirdre K. Mulligan, a lawyer and a professor in the School of Information at the University of California, Berkeley, who collaborates with technologists to advance privacy and other democratic values through technical design and policy;

I see they have representation from Israel, India, and the private sector as well. Refreshingly, there’s more than one woman on the standing committee and in this first study group. It’s good to see these efforts at inclusiveness and I’m particularly delighted with the inclusion of an organization from Asia. All too often inclusiveness means Europe, especially the UK. So, it’s good (and I think important) to see a different range of representation.

Music videos for teaching science and a Baba Brinkman update

I have two news bits concerning science and music.

Music videos and science education

Researchers in the US and New Zealand have published a study on how effective music videos are for teaching science. Hint: there are advantages but don’t expect perfection. From a May 25, 2016 news item on ScienceDaily,

Does “edutainment” such as content-rich music videos have any place in the rapidly changing landscape of science education? A new study indicates that students can indeed learn serious science content from such videos.

The study, titled ‘Leveraging the power of music to improve science education’ and published by International Journal of Science Education, examined over 1,000 students in a three-part experiment, comparing learners’ understanding and engagement in response to 24 musical and non-musical science videos.

A May 25, 2016 Taylor & Francis (publishers) press release, which originated the news item, quickly gets to the point,

The central findings were that (1) across ages and genders, K-16 students who viewed music videos improved their scores on quizzes about content covered in the videos, and (2) students preferred music videos to non-musical videos covering equivalent content.  Additionally, the results hinted that videos with music might lead to superior long-term retention of the content.

“We tested most of these students outside of their normal classrooms,” commented lead author Greg Crowther, Ph.D., a lecturer at the University of Washington.  “The students were not forced by their teachers to watch these videos, and they didn’t have the spectre of a low course grade hanging over their heads.  Yet they clearly absorbed important information, which highlights the great potential of music to deliver key content in an appealing package.”

The study was inspired by the classroom experiences of Crowther and co-author Tom McFadden [emphasis mine], who teaches science at the Nueva School in California.  “Tom and I, along with many others, write songs for and with our students, and we’ve had a lot of fun doing that,” said Crowther.  “But rather than just assuming that this works, we wanted to see whether we could document learning gains in an objective way.”

The findings of this study have implications for teacher practitioners, policy-makers and researchers who are looking for innovative ways to improve science education.  “Music will always be a supplement to, rather than a substitute for, more traditional forms of teaching,” said Crowther.  “But teachers who want to connect with their students through music now have some additional data on their side.”

The paper is quite interesting (two of the studies were run in the US and one in New Zealand) and I notice that Don McFadden of the Science Rap Academy is one of the authors (more about him later); here’s a link to and a citation for the paper,

Leveraging the power of music to improve science education by Gregory J. Crowther, Tom McFadden, Jean S. Fleming, & Katie Davis.  International Journal of Science Education

This paper is open access. As I noted earlier, the research is promising but science music videos are not the answer to all science education woes.

One of my more recent pieces featuring Tom McFadden and his Science Rap Academy is this April 21, 2015 posting. The 2016 edition of the academy started in January 2016 according to David Bruggeman’s Jan. 27, 2016 posting on his Pasco Phronesis blog. You can find the Science Rap Academy’s YouTube channel here and the playlist here.

Canadian science rappers and musicians

I promised the latest about Baba Brinkman and here it is (from a May 14, 2016 notice received via email,

Not many people know this, but Dylan Thomas [legendary Welsh poet] was one of my early influences as a poet and one of the reasons I was inspired to pursue versification as a career. Well now Literature Wales has commissioned me to write and record a new rap/poem in celebration of Dylan Day 2016 (today [May 14, 20160) which I dutifully did. You can watch the video here to check out what a hip-hop flow and a Thomas poem have in common.

In other news, I’ll be performing a couple of one-off show over the next few weeks. Rap Guide to Religion is on at NECSS in New York on May 15 (tomorrow) [Note: Link removed as the event date has now been passed] and Rap Guide to Evolution is at the Reason Rally in DC June 2nd [2016]. I’m also continuing with the off-Broadway run of Rap Guide to Climate Chaos, recording the climate chaos album and looking to my next round of writing and touring, so if you have ideas about venues I could play please send me a note.

You can find out more about Baba Brinkman (a Canadian rapper who has written and  performed many science raps and lives in New York) here.

There’s another Canadian who produces musical science videos, Tim Blais (physicist and Montréaler) who was most recently featured here in a Feb. 12, 2016 posting. You can find a selection of Blais’ videos on his A Capella Science channel on YouTube.

Light-captured energetics (harvesting light for optoelectronics)

Comparing graphene to a tiger is unusual but that’s what researcher Sanfeng Wu does—eventually—in a May 13, 2016 University of Washington news release (also on EurekAlert) about his work,

In the quest to harvest light for electronics, the focal point is the moment when photons — light particles — encounter electrons, those negatively-charged subatomic particles that form the basis of our modern electronic lives. If conditions are right when electrons and photons meet, an exchange of energy can occur. Maximizing that transfer of energy is the key to making efficient light-captured energetics possible.

“This is the ideal, but finding high efficiency is very difficult,” said University of Washington physics doctoral student Sanfeng Wu. “Researchers have been looking for materials that will let them do this — one way is to make each absorbed photon transfer all of its energy to many electrons, instead of just one electron in traditional devices.”

In traditional light-harvesting methods, energy from one photon only excites one electron or none depending on the absorber’s energy gap, transferring just a small portion of light energy into electricity. The remaining energy is lost as heat. But in a paper released May 13 in Science Advances, Wu, UW associate professor Xiaodong Xu and colleagues at four other institutions describe one promising approach to coax photons into stimulating multiple electrons. Their method exploits some surprising quantum-level interactions to give one photon multiple potential electron partners. Wu and Xu, who has appointments in the UW’s Department of Materials Science & Engineering and the Department of Physics, made this surprising discovery using graphene.

There has been intense research on graphene’s electrical properties but the researchers’ discovery adds a new property to be investigated (from the news release),

“Graphene is a substance with many exciting properties,” said Wu, the paper’s lead author. “For our purposes, it shows a very efficient interaction with light.”

Graphene is a two-dimensional hexagonal lattice of carbon atoms bonded to one another, and electrons are able to move easily within graphene. The researchers took a single layer of graphene — just one sheet of carbon atoms thick — and sandwiched it between two thin layers of a material called boron-nitride.

Boron-nitride is a material that has excited a great deal of interest in the last 12 to 18 months (from the news release),

“Boron-nitride has a lattice structure that is very similar to graphene, but has very different chemical properties,” said Wu. “Electrons do not flow easily within boron-nitride; it essentially acts as an insulator.”

Xu and Wu discovered that when the graphene layer’s lattice is aligned with the layers of boron-nitride, a type of “superlattice” is created with properties allowing efficient optoelectronics that researchers had sought. These properties rely on quantum mechanics, the occasionally baffling rules that govern interactions between all known particles of matter. Wu and Xu detected unique quantum regions within the superlattice known as Van Hove singularities.

Here’s an animated .gif illustrating the superlattice in action,

The news release goes on to describe the Van Hove singularities within the superlattice and to mention the ‘tiger’,

“These are regions of huge electron density of states, and they were not accessed in either the graphene or boron-nitride alone,” said Wu. “We only created these high electron density regions in an accessible way when both layers were aligned together.”

When Xu and Wu directed energetic photons toward the superlattice, they discovered that those Van Hove singularities were sites where one energized photon could transfer its energy to multiple electrons that are subsequently collected by electrodes— not just one electron or none with the remaining energy lost as heat. By a conservative estimate, Xu and Wu report that within this superlattice one photon could “kick” as many as five electrons to flow as current.

With the discovery of collecting multiple electrons upon the absorption of one photon, researchers may be able to create highly efficient devices that could harvest light with a large energy profit. Future work would need to uncover how to organize the excited electrons into electrical current for optimizing the energy-converting efficiency and remove some of the more cumbersome properties of their superlattice, such as the need for a magnetic field. But they believe this efficient process between photons and electrons represents major progress.

“Graphene is a tiger with great potential for optoelectronics, but locked in a cage,” said Wu. “The singularities in this superlattice are a key to unlocking that cage and releasing graphene’s potential for light harvesting application.”

Performances Tom Hanks never gave

The answer to the question, “What makes Tom Hanks look like Tom  Hanks?” leads to machine learning and algorithms according to a Dec. 7, 2015 University of Washington University news release (also on EurekAlert) Note: Link have been removed,

Tom Hanks has appeared in many acting roles over the years, playing young and old, smart and simple. Yet we always recognize him as Tom Hanks.

Why? Is it his appearance? His mannerisms? The way he moves?

University of Washington researchers have demonstrated that it’s possible for machine learning algorithms to capture the “persona” and create a digital model of a well-photographed person like Tom Hanks from the vast number of images of them available on the Internet.

With enough visual data to mine, the algorithms can also animate the digital model of Tom Hanks to deliver speeches that the real actor never performed.

“One answer to what makes Tom Hanks look like Tom Hanks can be demonstrated with a computer system that imitates what Tom Hanks will do,” said lead author Supasorn Suwajanakorn, a UW graduate student in computer science and engineering.

As for the performances Tom Hanks never gave, the news release offers more detail,

The technology relies on advances in 3-D face reconstruction, tracking, alignment, multi-texture modeling and puppeteering that have been developed over the last five years by a research group led by UW assistant professor of computer science and engineering Ira Kemelmacher-Shlizerman. The new results will be presented in a paper at the International Conference on Computer Vision in Chile on Dec. 16.

The team’s latest advances include the ability to transfer expressions and the way a particular person speaks onto the face of someone else — for instance, mapping former president George W. Bush’s mannerisms onto the faces of other politicians and celebrities.

Here’s a video demonstrating how former President Bush’s speech and mannerisms have mapped onto other famous faces including Hanks’s,

The research team has future plans for this technology (from the news release)

It’s one step toward a grand goal shared by the UW computer vision researchers: creating fully interactive, three-dimensional digital personas from family photo albums and videos, historic collections or other existing visuals.

As virtual and augmented reality technologies develop, they envision using family photographs and videos to create an interactive model of a relative living overseas or a far-away grandparent, rather than simply Skyping in two dimensions.

“You might one day be able to put on a pair of augmented reality glasses and there is a 3-D model of your mother on the couch,” said senior author Kemelmacher-Shlizerman. “Such technology doesn’t exist yet — the display technology is moving forward really fast — but how do you actually re-create your mother in three dimensions?”

One day the reconstruction technology could be taken a step further, researchers say.

“Imagine being able to have a conversation with anyone you can’t actually get to meet in person — LeBron James, Barack Obama, Charlie Chaplin — and interact with them,” said co-author Steve Seitz, UW professor of computer science and engineering. “We’re trying to get there through a series of research steps. One of the true tests is can you have them say things that they didn’t say but it still feels like them? This paper is demonstrating that ability.”

Existing technologies to create detailed three-dimensional holograms or digital movie characters like Benjamin Button often rely on bringing a person into an elaborate studio. They painstakingly capture every angle of the person and the way they move — something that can’t be done in a living room.

Other approaches still require a person to be scanned by a camera to create basic avatars for video games or other virtual environments. But the UW computer vision experts wanted to digitally reconstruct a person based solely on a random collection of existing images.

To reconstruct celebrities like Tom Hanks, Barack Obama and Daniel Craig, the machine learning algorithms mined a minimum of 200 Internet images taken over time in various scenarios and poses — a process known as learning ‘in the wild.’

“We asked, ‘Can you take Internet photos or your personal photo collection and animate a model without having that person interact with a camera?'” said Kemelmacher-Shlizerman. “Over the years we created algorithms that work with this kind of unconstrained data, which is a big deal.”

Suwajanakorn more recently developed techniques to capture expression-dependent textures — small differences that occur when a person smiles or looks puzzled or moves his or her mouth, for example.

By manipulating the lighting conditions across different photographs, he developed a new approach to densely map the differences from one person’s features and expressions onto another person’s face. That breakthrough enables the team to ‘control’ the digital model with a video of another person, and could potentially enable a host of new animation and virtual reality applications.

“How do you map one person’s performance onto someone else’s face without losing their identity?” said Seitz. “That’s one of the more interesting aspects of this work. We’ve shown you can have George Bush’s expressions and mouth and movements, but it still looks like George Clooney.”

$81M for US National Nanotechnology Coordinated Infrastructure (NNCI)

Academics, small business, and industry researchers are the big winners in a US National Science Foundation bonanza according to a Sept. 16, 2015 news item on Nanowerk,

To advance research in nanoscale science, engineering and technology, the National Science Foundation (NSF) will provide a total of $81 million over five years to support 16 sites and a coordinating office as part of a new National Nanotechnology Coordinated Infrastructure (NNCI).

The NNCI sites will provide researchers from academia, government, and companies large and small with access to university user facilities with leading-edge fabrication and characterization tools, instrumentation, and expertise within all disciplines of nanoscale science, engineering and technology.

A Sept. 16, 2015 NSF news release provides a brief history of US nanotechnology infrastructures and describes this latest effort in slightly more detail (Note: Links have been removed),

The NNCI framework builds on the National Nanotechnology Infrastructure Network (NNIN), which enabled major discoveries, innovations, and contributions to education and commerce for more than 10 years.

“NSF’s long-standing investments in nanotechnology infrastructure have helped the research community to make great progress by making research facilities available,” said Pramod Khargonekar, assistant director for engineering. “NNCI will serve as a nationwide backbone for nanoscale research, which will lead to continuing innovations and economic and societal benefits.”

The awards are up to five years and range from $500,000 to $1.6 million each per year. Nine of the sites have at least one regional partner institution. These 16 sites are located in 15 states and involve 27 universities across the nation.

Through a fiscal year 2016 competition, one of the newly awarded sites will be chosen to coordinate the facilities. This coordinating office will enhance the sites’ impact as a national nanotechnology infrastructure and establish a web portal to link the individual facilities’ websites to provide a unified entry point to the user community of overall capabilities, tools and instrumentation. The office will also help to coordinate and disseminate best practices for national-level education and outreach programs across sites.

Saharan silver ants: the nano of it all (science and technology)

Researchers at Columbia University (US) are on quite a publishing binge lately. The latest is a biomimicry story where researchers (from Columbia amongst other universities and including Brookhaven National Laboratory, which has issued its own news release) have taken a very close look at Saharan silver ants to determine how they stay cool in one of the hottest climates in the world. From a June 18, 2015 Columbia University news release (also on EurekAlert), Note: Links have been removed,

Nanfang Yu, assistant professor of applied physics at Columbia Engineering, and colleagues from the University of Zürich and the University of Washington, have discovered two key strategies that enable Saharan silver ants to stay cool in one of the hottest terrestrial environments on Earth. Yu’s team is the first to demonstrate that the ants use a coat of uniquely shaped hairs to control electromagnetic waves over an extremely broad range from the solar spectrum (visible and near-infrared) to the thermal radiation spectrum (mid-infrared), and that different physical mechanisms are used in different spectral bands to realize the same biological function of reducing body temperature. Their research, “Saharan silver ants keep cool by combining enhanced optical reflection and radiative heat dissipation,” is published June 18 [2015] in Science magazine.

The Columbia University news release expands on the theme,

“This is a telling example of how evolution has triggered the adaptation of physical attributes to accomplish a physiological task and ensure survival, in this case to prevent Saharan silver ants from getting overheated,” Yu says. “While there have been many studies of the physical optics of living systems in the ultraviolet and visible range of the spectrum, our understanding of the role of infrared light in their lives is much less advanced. Our study shows that light invisible to the human eye does not necessarily mean that it does not play a crucial role for living organisms.”

The project was initially triggered by wondering whether the ants’ conspicuous silvery coats were important in keeping them cool in blistering heat. Yu’s team found that the answer to this question was much broader once they realized the important role of infrared light. Their discovery that there is a biological solution to a thermoregulatory problem could lead to the development of novel flat optical components that exhibit optimal cooling properties.

“Such biologically inspired cooling surfaces will have high reflectivity in the solar spectrum and high radiative efficiency in the thermal radiation spectrum,” Yu explains. “So this may generate useful applications such as a cooling surface for vehicles, buildings, instruments, and even clothing.”

Saharan silver ants (Cataglyphis bombycina) forage in the Saharan Desert in the full midday sun when surface temperatures reach up to 70°C (158°F), and they must keep their body temperature below their critical thermal maximum of 53.6°C (128.48°F) most of the time. In their wide-ranging foraging journeys, the ants search for corpses of insects and other arthropods that have succumbed to the thermally harsh desert conditions, which they are able to endure more successfully. Being most active during the hottest moment of the day also allows these ants to avoid predatory desert lizards. Researchers have long wondered how these tiny insects (about 10 mm, or 3/8” long) can survive under such thermally extreme and stressful conditions.

Using electron microscopy and ion beam milling, Yu’s group discovered that the ants are covered on the top and sides of their bodies with a coating of uniquely shaped hairs with triangular cross-sections that keep them cool in two ways. These hairs are highly reflective under the visible and near-infrared light, i.e., in the region of maximal solar radiation (the ants run at a speed of up to 0.7 meters per second and look like droplets of mercury on the desert surface). The hairs are also highly emissive in the mid-infrared portion of the electromagnetic spectrum, where they serve as an antireflection layer that enhances the ants’ ability to offload excess heat via thermal radiation, which is emitted from the hot body of the ants to the cold sky. This passive cooling effect works under the full sun whenever the insects are exposed to the clear sky.

“To appreciate the effect of thermal radiation, think of the chilly feeling when you get out of bed in the morning,” says Yu. “Half of the energy loss at that moment is due to thermal radiation since your skin temperature is temporarily much higher than that of the surrounding environment.”

The researchers found that the enhanced reflectivity in the solar spectrum and enhanced thermal radiative efficiency have comparable contributions to reducing the body temperature of silver ants by 5 to 10 degrees compared to if the ants were without the hair cover. “The fact that these silver ants can manipulate electromagnetic waves over such a broad range of spectrum shows us just how complex the function of these seemingly simple biological organs of an insect can be,” observes Norman Nan Shi, lead author of the study and PhD student who works with Yu at Columbia Engineering.

Yu and Shi collaborated on the project with Rüdiger Wehner, professor at the Brain Research Institute, University of Zürich, Switzerland, and Gary Bernard, electrical engineering professor at the University of Washington, Seattle, who are renowned experts in the study of insect physiology and ecology. The Columbia Engineering team designed and conducted all experimental work, including optical and infrared microscopy and spectroscopy experiments, thermodynamic experiments, and computer simulation and modeling. They are currently working on adapting the engineering lessons learned from the study of Saharan silver ants to create flat optical components, or “metasurfaces,” that consist of a planar array of nanophotonic elements and provide designer optical and thermal radiative properties.

Yu and his team plan next to extend their research to other animals and organisms living in extreme environments, trying to learn the strategies these creatures have developed to cope with harsh environmental conditions.

“Animals have evolved diverse strategies to perceive and utilize electromagnetic waves: deep sea fish have eyes that enable them to maneuver and prey in dark waters, butterflies create colors from nanostructures in their wings, honey bees can see and respond to ultraviolet signals, and fireflies use flash communication systems,” Yu adds. “Organs evolved for perceiving or controlling electromagnetic waves often surpass analogous man-made devices in both sophistication and efficiency. Understanding and harnessing natural design concepts deepens our knowledge of complex biological systems and inspires ideas for creating novel technologies.”

Next, there’s the perspective provided by Brookhaven National Laboratory in a June 18, 2015 news item on Nanowerk (Note: It is very similar to the Columbia University news release but it takes a turn towards the technical challenges as you’ll see if you keep reading),

The paper, published by Columbia Engineering researchers and collaborators—including researchers from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory—describes how the nanoscale structure of the hairs helps increase the reflectivity of the ant’s body in both visible and near-infrared wavelengths, allowing the insects to deflect solar radiation their bodies would otherwise absorb. The hairs also enhance emissivity in the mid-infrared spectrum, allowing heat to dissipate efficiently from the hot body of the ants to the cool, clear sky.

A June 18, 2015 BNL news release by Alasdair Wilkins, which originated the Nanowerk news item, describes the collaboration between the researchers and the special adjustments made to the equipment in service of this project (Note: A link has been removed),

In a typical experiment involving biological material such as nanoscale hairs, it would usually be sufficient to use an electron microscope to create an image of the surface of the specimen. This research, however, required Yu’s group to look inside the ant hairs and produce a cross-section of the structure’s interior. The relatively weak beam of electrons from a standard electron microscope would not be able to penetrate the surface of the sample.

The CFN’s dual beam system solves the problem by combining the imaging of an electron microscope with a much more powerful beam of gallium ions.  With 31 protons and 38 neutrons, each gallium ion is about 125,000 times more massive than an electron, and massive enough to create dents in the nanoscale structure – like throwing a stone against a wall. The researchers used these powerful beams to drill precise cuts into the hairs, revealing the crucial information hidden beneath the surface. Indeed, this particular application, in which the system was used to investigate a biological problem, was new for the team at CFN.

“Conventionally, this tool is used to produce cross-sections of microelectronic circuits,” said Camino. “The focused ion beam is like an etching tool. You can think of it like a milling tool in a machine shop, but at the nanoscale. It can remove material at specific places because you can see these locations with the SEM. So locally you remove material and you look at the under layers, because the cuts give you access to the cross section of whatever you want to look at.”

The ant hair research challenged the CFN team to come up with novel solutions to investigate the internal structures without damaging the more delicate biological samples.

“These hairs are very soft compared to, say, semiconductors or crystalline materials. And there’s a lot of local heat that can damage biological samples. So the parameters have to be carefully tuned not to do much damage to it,” he said. “We had to adapt our technique to find the right conditions.”

Another challenge lay in dealing with the so-called charging effect. When the dual beam system is trained on a non-conducting material, electrons can build up at the point where the beams hit the specimen, distorting the resulting image. The team at CFN was able to solve this problem by placing thin layers of gold over the biological material, making the sample just conductive enough to avoid the charging effect.

Revealing Reflectivity

While Camino’s team focused on helping Yu’s group investigate the structure of the ant hairs, Matthew Sfeir’s work with high-brightness Fourier transform optical spectroscopy helped to reveal how the reflectivity of the hairs helped Saharan silver ants regulate temperature. Sfeir’s spectrometer revealed precisely how much those biological structures reflect light across multiple wavelengths, including both visible and near-infrared light.

“It’s a multiplexed measurement,” Sfeir said, explaining his team’s spectrometer. “Instead of tuning through this wavelength and this wavelength, that wavelength, you do them all in one swoop to get all the spectral information in one shot. It gives you very fast measurements and very good resolution spectrally. Then we optimize it for very small samples. It’s a rather unique capability of CFN.”

Sfeir’s spectroscopy work draws on knowledge gained from his work at another key Brookhaven facility: the original National Synchrotron Light Source, where he did much of his postdoc work. His experience was particularly useful in analyzing the reflectivity of the biological structures across many different wavelengths of the electromagnetic spectrum.

“This technique was developed from my experience working with the infrared synchrotron beamlines,” said Sfeir. “Synchrotron beamlines are optimized for exactly this kind of thing. I thought, ‘Hey, wouldn’t it be great if we could develop a similar measurement for the type of solar devices we make at CFN?’ So we built a bench-top version to use here.”

Improving battery electrodes and air filters with a ‘transistorized’ carbon nanotube for more precise measurements

Researchers at the University of Washington (state) have been able to use carbon nanotubes to make the most precise measurements yet of the interactions between gas and carbon atoms. From a May 28, 2015 news item on Nanotechnology Now,

Physicists at the University of Washington have conducted the most precise and controlled measurements yet of the interaction between the atoms and molecules that comprise air and the type of carbon surface used in battery electrodes and air filters — key information for improving those technologies.

A May 28, 2015 University of Washington news release (also on EurekAlert), which originated the news item, describes the work in more detail,

A team led by David Cobden, UW professor of physics, used a carbon nanotube — a seamless, hollow graphite structure a million times thinner than a drinking straw — acting as a transistor to study what happens when gas atoms come into contact with the nanotube’s surface. …

Cobden said he and co-authors found that when an atom or molecule sticks to the nanotube a tiny fraction of the charge of one electron is transferred to its surface, resulting in a measurable change in electrical resistance.

“This aspect of atoms interacting with surfaces has never been detected unambiguously before,” Cobden said. “When many atoms are stuck to the miniscule tube at the same time, the measurements reveal their collective dances, including big fluctuations that occur on warming analogous to the boiling of water.”

Lithium batteries involve lithium atoms sticking and transferring charges to carbon electrodes, and in activated charcoal filters, molecules stick to the carbon surface to be removed, Cobden explained.

“Various forms of carbon, including nanotubes, are considered for hydrogen or other fuel storage because they have a huge internal surface area for the fuel molecules to stick to. However, these technological situations are extremely complex and difficult to do precise, clear-cut measurements on.”

This work, he said, resulted in the most precise and controlled measurements of these interactions ever made, “and will allow scientists to learn new things about the interplay of atoms and molecules with a carbon surface,” important for improving technologies including batteries, electrodes and air filters.

Nanopollution of marine life

Concerns are being raised about nanosunscreens and nanotechnology-enabled marine paints and their effect on marine life, specifically, sea urchins. From a May 13, 2015 news item on Nanowerk (Note: A link has been removed),

Nanomaterials commonly used in sunscreens and boat-bottom paints are making sea urchin embryos more vulnerable to toxins, according to a study from the University of California, Davis [UC Davis]. The authors said this could pose a risk to coastal, marine and freshwater environments.

The study, published in the journal Environmental Science and Technology (“Copper Oxide and Zinc Oxide Nanomaterials Act as Inhibitors of Multidrug Resistance Transport in Sea Urchin Embryos: Their Role as Chemosensitizers”), is the first to show that the nanomaterials work as chemosensitizers. In cancer treatments, a chemosensitizer makes tumor cells more sensitive to the effects of chemotherapy.

Similarly, nanozinc and nanocopper made developing sea urchin embryos more sensitive to other chemicals, blocking transporters that would otherwise defend them by pumping toxins out of cells.

A May 12, 2015 UC Davis news release, which originated the news item, includes some cautions,

Nanozinc oxide is used as an additive in cosmetics such as sunscreens, toothpastes and beauty products. Nanocopper oxide is often used for electronics and technology, but also for antifouling paints, which prevent things like barnacles and mussels from attaching to boats.

“At low levels, both of these nanomaterials are nontoxic,” said co-author Gary Cherr, professor and interim director of the UC Davis Bodega Marine Laboratory, and an affiliate of the UC Davis Coastal Marine Sciences Institute. “However, for sea urchins in sensitive life stages, they disrupt the main defense mechanism that would otherwise protect them from environmental toxins.”

Science for safe design

Nanomaterials are tiny chemical substances measured in nanometers, which are about 100,000 times smaller than the diameter of a human hair. Nano-sized particles can enter the body through the skin, ingestion, or inhalation. They are being rapidly introduced across the fields of electronics, medicine and technology, where they are being used to make energy efficient batteries, clean up oil spills, and fight cancer, among many other uses. However, relatively little is known about nanomaterials with respect to the environment and health.

While this research into nanoparticles as chemosensitizers is, according to UC Davis, the first of its kind, the concern over nanosunscreens and marine waters has been gaining traction over the last few years. For example, there’s  research featured in a June 10, 2013 article by Roberta Kwok for the University of Washington’s ‘Conservation This Week’ magazine,

Sunscreen offers protection from UV rays, reduces the risk of skin cancer, and even slows down signs of aging. Unfortunately, researchers have found that sunscreen also pollutes the ocean.

Although people have been using these products for decades, “the effect of sunscreens, as a source of introduced chemicals to the coastal marine system, has not yet been addressed,” a research team writes in PLOS ONE. Sunscreens contain chemicals not only for UV protection, but also for coloring, fragrance, and texture. And beaches are becoming ever-more-popular vacation spots; for example, nearly 10 million tourists visited Majorca Island in the Mediterranean Sea in 2010.

Little skates, mermaid purses, nature, and writers

GrrlScientist has written a fascinating ;piece about skates (fish), poetry, and Twitter for her Dec. 5, 2013 posting on the Guardian Science Blog network (Note: A link has been removed),

Twitter is a wonderful medium. For example, a couple days ago, I met University of Washington Biology Professor Adam Summers on twitter. It turns out that he is Associate Director of Friday Harbor Labs, where I spent a summer taking an intensive molecular neurobiology course during my graduate training in zoology. …

“Skates are fabulous animals”, Professor Summers writes in email.

“They make up a quarter of the diversity of cartilaginous fishes and every darn one of the 250 species looks pretty much exactly like every other one.”

Thus, studies into the anatomy and development of one species may provide insight into these processes for other, rarer, species.

“The little skate, also called the hedgehog skate, was one of my go-to organisms for many years”, writes Professor Summers in email.

These studies provide the basis for a physical or a mathematical model that may help understand function. This model is of course tested both against its inspiration and as a predictive tool. For example, the skate’s tail is very important, even for the developing embryo.

“I figured out that it can’t survive on the oxygen that diffuses through the capsule. Instead it has to pump water through by vibrating its tail.”

Perhaps this is the reason that the tail muscles differ from what’s considered normal.

“A wonderful muscle physiologist showed that the muscle in the tail is cardiac muscle rather than the striated muscle it should be”, Professor Summers writes.

While colleagues thought Summers’ specimens were good enough to be compared to visual art, his little skate specimens also inspired a poet (from the posting),

“I got chatting with a friend who teaches a poetry class up here [at Friday Harbor]. Sierra Nelson and I had several long conversations about the similarity of the lens that poets and scientists bring to the world.”

“I think the poem does a much better job of engaging the viewer than my dry prose on the critter.”

Little Skate
Leucoraja erinacea

Littlest of little skates, just barely hatched!
You can still see the remnants
of my yellow egg sac.

And my tail’s a little longer
than my whole body
(I’ll grow into it more eventually).

….

Adam Summers shared one of his images of his ‘stained’ little skate specimens on his twitter feed (pic.twitter.com/UWCKeVMmYB)

Here's an embryo of the little skate, Leucoraja erinacea. pic.twitter.com/UWCKeVMmYB

I recommend reading GrrlScientist’s posting (Inside a mermaid’s purse; A poetic intersection between life and science, art and photography) for the whole story and, for that matter, the whole poem. As for the mermaid purse, this is the name for the little skate’s egg sack when found on the beach.

This all reminded me of Aileen Penner, a writer, poet, and science communications specialist located in Vancouver, Canada and her work in science and creative writing. She wrote a Nov. 19, 2013 posting about the intersection of nature and writing titled: US Forest Service Scientist Says Writers Help Gather “Cultural Data” on our Relationship With the Natural World (Note: Links have been removed),

Who is Fred Swanson you ask? Yes he is a retired U.S. Forest Service scientist and yes he is a Forest Ecology Professor at Oregon State University (OSU), but he is also a key figure in the Spring Creek Project for Ideas, Nature, and the Written Word. This is a program I have been following since 2006 and greatly admire for their commitment to bring together “the practical wisdom of the environmental sciences, the clarity of philosophical analysis, and the creative, expressive power of the written word, to find new ways to understand and re-imagine our relation to the natural world.”

In April of 2012, I went to OSU to interview the Director of the Spring Creek Project, Charles Goodrich. I wanted to know how to fund such a long-term interdisciplinary project. Charles talked a lot about Fred Swanson and his enthusiasm for having writers as part of the inquiry process and about Swanson’s personal commitment to writing the arts into scientific funding proposals for his work at the H.J. Andrew Experimental Forest.

Penner was inspired by an Andrew C. Gottleib article (About Earth Scientist Fred Swanson) in Terrain’s Fall 2013 issue and quotes from it throughout her own posting. She also notes this (Note: Links have been removed),

Terrain interviewer Andrew Gottlieb will moderate a panel “Artists in the Old-Growth” with Alison Hawthorne Deming, Fred Swanson, Charles Goodrich and Spring Creek Project Founder, Kathleen Dean Moore at the upcoming AWP conference in Seattle on February 27, 2014. If you are in Seattle for this – go see it!

Before investigating the Association of Writers and Writing Programs (AWP) 2014 conference and the special session any further, here’s a bit more information about the Spring Creek Project for Ideas, Nature, and the Written Word, from the homepage,

Spring Creek Project engages the most daunting and urgent environmental issues of our times while remembering and sharing our perennial sources of joy, wonder, and gratitude. We are a convening organization that sponsors writers’ residencies, readings, lectures, conversations, and symposia on issues and themes of critical importance to the health of humans and nature. We believe sharing insights, inspiration, and methods from many perspectives increases our understanding of the place of humans in nature. Our goal is to include participants and audience members from every discipline and persuasion, from creative writing and the other arts, from the environmental and social sciences, from philosophy and other humanistic disciplines.

The AWP conference seems mainly focused on fiction and literary nonfiction (at least, that’s what the video highlights [on the 2014 conference homepage] of the 2013 conference would suggest). Here’s more from the 2014 AWP conference homepage,

Each year, AWP holds its Annual Conference & Bookfair in a different city to celebrate the authors, teachers, students, writing programs, literary centers, and publishers of that region. More than 12,000 writers and readers attended our 2013 conference, and over 650 exhibitors were represented at our bookfair. AWP’s is now the largest literary conference in North America. We hope you’ll join us in 2014.

Your grandma got STEM?

Jeff Bittel thank you for a story (Mar. 26, 2013 on Slate) about Rachel Levy and the website where she gently blows up the notion/stereotype that older women don’t understand science and technology and that they are too old to learn (Note: A link has been removed),

 Is your grandmother a particle physicist? Did she help the Navy build submarines or make concoctions of chlorine gas on the family’s front porch? Or is she a mathematician, inventor, or engineer? If so, then baby, your grandma’s got STEM.

Grandma Got STEM is a celebration of women working in and contributing to the fields of science, technology, engineering, and mathematics. It is also designed to combat the doting, fumbling, pie-making stereotype of grandmatrons.

That’s why Rachel Levy, an associate professor of mathematics at Harvey Mudd College, is collecting the stories of grandmas across the various fields of STEM. She first got the idea after hearing someone utter the phrase, “Just explain it like you would to your grandma.”

At first blush, such a thing seems harmless. But think about what it means—basically, all older women are stupid.

“For two or three years I thought about how I could address this issue without just making people angry and more inclined to use the phrase,” Levy told me. “If I could come up with a million examples of grandmothers who were tech-savvy, people wouldn’t say it anymore because it wouldn’t be apt.”

While attending the conference ScienceOnline this year, Levy realized she could harness the power of the Internet to collect stories and showcase them. So far, she’s been able to upload at least one grandma a day for about a month and a half—and the stories keep pouring in. Levy’s aim so far is to be as inclusive as possible. She’s accepting any grandma currently or previously involved in STEM. They can submit themselves or you can submit for them. Heck, they don’t even have to have children with children, per se. Age’ll do just fine.

Bittel might want to reconsider that bit about children and children with children. That can be a touchy topic.

Levy’s solution was to create the Grandma Got STEM website. From the Mar. 27, 2013 posting about Mary Vellos Klonowski,

GrandmaGotSTEM

Thank you to undergraduate Math/Computer Science Major Joey Klonowski, who submitted this post about his grandmother:

This photo is from the October 3, 1951 edition of The Southtown Economist, a daily newspaper on the South Side of Chicago, when my grandmother, Mary Klonowski, was 18. She attended DePaul University against the wishes of her father, who didn’t want his daughters to be college educated. She received a BS from DePaul in 1954 and was the only woman chemistry major in her class. She later earned a master’s in mathematics education and became a high school math teacher. She is now 80 years old and still working as a substitute teacher.

There are a lot of stories (covering quite the range of grannies) on the site. Levy is asking for international submissions as well,

Seeking international submissions!

Getting back to Bittel’s Slate article, he mentions Foldit (here’s my first piece in an Aug. 6, 2010 posting [scroll down about 1/2 way]), a protein-folding game which has generated some very exciting science. He also notes some of that science was generated by older, ‘uneducated’ women. Bittel linked to Jeff Howe’s Feb. 27, 2012 article about Foldit and other crowdsourced science projects for Slate where I found this very intriguing bit,

“You’d think a Ph.D. in biochemistry would be very good at designing protein molecules,” says Zoran Popović, the University of Washington game designer behind Foldit. Not so. “Biochemists are good at other things. But Foldit requires a narrow, deeper expertise.”

Or as it turns out, more than one. Some gamers have a preternatural ability to recognize patterns, an innate form of spatial reasoning most of us lack. Others—often “grandmothers without a high school education,” says Popovic—exercise a particular social skill. “They’re good at getting people unstuck. They get them to approach the problem differently.” What big pharmaceutical company would have anticipated the need to hire uneducated grandmothers? (I know a few, if Eli Lilly HR is thinking of rejiggering its recruitment strategy.) [emphases mine]

There’s an interesting question and I didn’t see it answered in Howe’s article. What kind of grandmother who doesn’t have high school graduation joins a protein-folding game? I ask because neither of my parents had or have a high school education. Neither of them would have joined the game as neither would have had the confidence.

What I’ve tried to present here is a range of possibilities regarding age and education. Being older (female especially but also male, on occasion) doesn’t equal stupidity. As for education, I’ve never found that having high school graduation or a university degree(s) to be a guarantor of an exciting intellect. I mention these two points because it seems to me that people are being ranked as to age and education in ways that are unnecessarily exclusionary. Thank goodness for games like Foldit and websites like Grandma’s Got STEM which suggest alternatives to this relentless and ruthless form of ranking which disallows participation from the great bulk of us.
