Intelligence Squared (IQ2US) was featured here in a January 18, 2019 posting when the organization hosted a ‘de-extinction’ (or ‘resurrection’) biology debate. I was quite impressed with the quality of the arguments, pro and con (for and against) and the civility with which the participants conducted themselves. Fingers crossed their upcoming Nov. 6, 2020 debate proves as satisfying.
It should be noted that Bloomberg TV is co-hosting this event with Intelligence Squared (IQ2US) and IBM is sponsoring it.
Here’s more about the debate on the motion: A U.S.-China Space Race Is Good for Humanity, from an Oct. 26, 2020 Shore Fire announcement (received via email),
Next Friday evening [Nov. 6, 2020] at 7:00 pm ET, the nonprofit debate series Intelligence Squared U.S. will hold a live debate on the motion “A U.S.-China Space Race Is Good for Humanity.”
Two of their debaters have released statements commenting on today’s news [emphasis mine; I have included information about the Oct. 26, 2020 news after this event information] out of NASA. One, Bidushi Bhattacharya, is a twenty-year veteran of NASA. The other, Avi Loeb, is one of the most prominent scientists working on space today.
… they will be debating for the motion “A U.S.-China Space Race Is Good for Humanity” with Intelligence Squared U.S. … . The debate will be viewable on Bloomberg TV’s new show ‘That’s Debatable’. Their opponents are Michio Kaku and Rajeswari Pillai Rajagopalan.
AVI LOEB STATEMENT:
“It was already known from previous studies that there is water ice on the lunar surface. But the new study identified that it is more abundant and exists all over the Moon. Interestingly, a month ago we published a paper with my former postdoc, Manasvi Lingam, arguing that liquid water may exist deep under the surface of the Moon and support sub-surface life.
“The existence of significant amounts of water on the lunar surface can be helpful for establishing a sustainable base there in the context of NASA’s Artemis program with its international partners. This will be the first step in advancing humanity to more distant destinations, such as Mars and beyond. There is no doubt that our future lies in space, not only for national security and commercial benefits but mainly for scientific exploration aimed at opening new horizons to our civilization. Earlier in October , eight countries signed the Artemis Accords , a set of international agreements drawn up by the US concerning future exploration of the Moon and the use of its resources. The Accords recognize that exploration of the Moon should be for peaceful purposes.
“In analogy with the scientific exploration conducted in the South Pole, it would be particularly interesting to search for life under the surface of the Moon once we establish a scientific base there.”
BIDUSHI BHATTACHARYA STATEMENT
“Today’s [Oct. 26, 2020] announcement has huge implications for the commercial development space sector. Private companies and startups now have a new product development opportunity. I can see a path for leveraging today’s off-planet capabilities to develop AI-based robotics to provide water extraction services for NASA, so that the agency can continue to focus on R&D.”

They found water (rather than the ice they had found before) on the moon and announced it on Oct. 26, 2020. To be more specific, they found the water in a crater named after a Jesuit priest, Christopher Clavius, who was also an astronomer and a mathematician. Given that piece of information it’s perhaps not that surprising that my cursory search yielded (near the top of the list) an Oct. 26, 2020 article about the discovery, Clavius, and the Jesuits’ interest in the stars by Molly Cahill for America Magazine The Jesuit Review (Note: Links have been removed),
On Oct. 26 , NASA’s Stratospheric Observatory for Infrared Astronomy, or SOFIA, announced the discovery of water on the moon. The water was discovered on the moon’s sunlit surface, which “indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places,” according to a press release.
His [Christopher Clavius] observance in 1560 of a total solar eclipse as a student inspired his life’s work: astronomy. Clavius is known for his work on refining and modifying the modern Gregorian calendar, and as Billy Critchley-Menor, S.J., wrote in America, Clavius was even called the “Euclid of the 16th century” before his death in 1612. He was one of the first mathematicians in the West to popularize the use of the decimal point, and his contributions to astronomy influenced Galileo, even though Clavius himself assented to a geocentric solar system, believing the heavens rotated around the Earth.
On Friday, November 6  at 7:00 PM ET Bloomberg Television will present the second episode of the new limited series “That’s Debatable,” presented in partnership with Intelligence Squared U.S. and sponsored exclusively by IBM, with an episode debating the motion “A U.S.-China Space Race Is Good for Humanity.” China is ramping up its national space industry with huge investments in next-generation technologies that promise to transform military, economic, and political realities. Could the U.S.-China space race drive innovation, rally public support for science and discovery, and launch humans into the next generation? Or would this competition catalyze an expensive global arms race, militarize space for decades to come, and destroy any hope of international peace and cohesion in the future?
Arguing in favor of the motion “A U.S.-China Space Race Is Good for Humanity” are Harvard physicist and member of the President’s Council of Advisors on Science and Technology at the White House Avi Loeb and rocket scientist Bidushi Bhattacharya, who spent two decades with NASA working on the Hubble Space Telescope and Galileo probe. Arguing against the motion are theoretical physicist Michio Kaku, a co-founder of String Field Theory, and nuclear weapons and space policy expert Rajeswari Pillai Rajagopalan.
Filmed in front of a live virtual audience, “That’s Debatable” will be conducted in the traditional Oxford-style format with two teams of two subject matter experts debating over four rounds, moderated by veteran Intelligence Squared U.S. moderator John Donvan. The live virtual audience will vote via mobile for or against the motion to determine the winner, to be announced at the conclusion of the program.
“That’s Debatable” also presents some of the first AI-aided debates, designed to demonstrate how AI can be used to bring a larger, more diverse range of voices and opinions to the public square. …
During the debate, IBM Watson plans to use Key Point Analysis, a new capability in Natural Language Processing (NLP) developed by the same IBM Research team that created Project Debater, which is designed to analyze viewer submitted arguments [deadline was Oct. 18, 2020] and provide insight into the global public opinion on each episode’s debate topic.
… [Note: The BIOS for those ‘arguing for the motion’ is in the Oct. 26, 2020 announcement excerpted near the beginning of this post]
Michio Kaku is one of the most widely recognized figures in science. He is a theoretical physicist, international bestselling author, and co-founder of String Field Theory. His most recent book, “Future of Humanity,” projects the future of the space program centuries into the future. Kaku is a professor at the City University of New York.

“Eat your vitamins” might be replaced with “ingest your ceramic nano-particles” in the future as space research is giving more weight to the idea that nanoscopic particles could help protect cells from common causes of damage.
Oxidative stress occurs in our bodies when cells lose the natural balance of electrons in the molecules that we are made of. This is a common and constant occurrence that is part of our metabolism but also plays a role in the aging process and several pathological conditions, such as heart failure, muscle atrophy and Parkinson’s disease.
The best advice for keeping your body in balance and avoiding oxidative stress is still to have a healthy diet and eat enough vitamins, but nanoparticles are showing promising results in keeping cells in shape.
When in space, astronauts have been shown to suffer from more oxidative stress due to the extra radiation they receive and as a by-product of floating in weightlessness, so researchers in Italy were keen to see if nanoparticles would have the same protective effect on cells on the International Space Station as on Earth.
They prepared muscle cells that flew to the International Space Station and were cultured in ESA’s Kubik incubator before being frozen for storage.
“A year ago [emphasis mine] our frozen samples splashed down in the Pacific Ocean on the Dragon spacecraft, and after comparing the samples we saw a marked effect in the cells treated with ceramic nanoparticles,” says Gianni Ciofani from the Istituto Italiano di Tecnologia in Italy. “The effect we observed seems to imply that nanoparticles work better and longer than traditional antioxidants such as vitamins.”
“The experiment setup resulted in excellent samples to analyze using state-of-the art RNA sequencing,” continues Gianni. “Conducting space research is nothing like traditional lab work, as we have less samples, we cannot do the work ourselves and we have to work around deadlines such as launch days, landing and storing the samples, it is challenging but thrilling research!” The team even found ways to improve and simplify the process for future studies.
Baby astronauts hypothesis
The research adds weight to the baby-astronaut hypothesis of weightlessness. The changes in muscle tissue observed are similar to how babies’ tissues develop in the womb.
“Some researchers see similarities to how human bodies adapt to living in space with pre-natal conditions: there are similarities with floating in a warm environment with different oxygen intake and we consider it a possibility of return to the state,” says Giada Genchi, also of the Istituto Italiano di Tecnologia’s Smart Bio-Interfaces department.
The team’s high-quality muscle tissue samples are being further analyzed and compared to samples from similar experiments that flew earlier. There is still much more to learn, such as what is the best way to administer nano-ceramics and how long do their protective effects last as well as possible unwanted side effects.
I highlighted a “A year ago” because that should mean 2019 but the research the ESA press release linked to was published in 2018. I cannot find anything more recent. So, for the curious, here’s a link to and a citation for the 2018 research paper,
I have some news about conserving art; early bird registration deadlines for two events, and, finally, an announcement about contest winners.
Canadian Light Source (CLS) and modern art
This is one of three pieces by Rita Letendre that underwent chemical mapping according to an August 5, 2020 CLS news release by Victoria Martinez (also received via email),
Research undertaken at the Canadian Light Source (CLS) at the University of Saskatchewan was key to understanding how to conserve experimental oil paintings by Rita Letendre, one of Canada’s most respected living abstract artists.
The work done at the CLS was part of a collaborative research project between the Art Gallery of Ontario (AGO) and the Canadian Conservation Institute (CCI) that came out of a recent retrospective Rita Letendre: Fire & Light at the AGO. During close examination, Meaghan Monaghan, paintings conservator from the Michael and Sonja Koerner Centre for Conservation, observed that several of Letendre’s oil paintings from the fifties and sixties had suffered significant degradation, most prominently, uneven gloss and patchiness, snowy crystalline structures coating the surface known as efflorescence, and cracking and lifting of the paint in several areas.
Kate Helwig, Senior Conservation Scientist at the Canadian Conservation Institute, says these problems are typical of mid-20th century oil paintings. “We focused on three of Rita Letendre’s paintings in the AGO collection, which made for a really nice case study of her work and also fits into the larger question of why oil paintings from that period tend to have degradation issues.”
Growing evidence indicates that paintings from this period have experienced these problems due to the combination of the experimental techniques many artists employed and the additives paint manufacturers had begun to use.
In order to determine more precisely how these factors affected Letendre’s paintings, the research team members applied a variety of analytical techniques, using microscopic samples taken from key points in the works.
“The work done at the CLS was particularly important because it allowed us to map the distribution of materials throughout a paint layer such as an impasto stroke,” Helwig said. The team used Mid-IR chemical mapping at the facility, which provides a map of different molecules in a small sample.
For example, chemical mapping at the CLS allowed the team to understand the distribution of the paint additive aluminum stearate throughout the paint layers of the painting Méduse. This painting showed areas of soft, incompletely dried paint, likely due to the high concentration and incomplete mixing of this additive.
The painting Victoire had a crumbling base paint layer in some areas and cracking and efflorescence at the surface in others. Infrared mapping at the CLS allowed the team to determine that excess free fatty acids in the paint were linked to both problems; where the fatty acids were found at the base they formed zing “soaps” which led to crumbling and cracking, and where they had moved to the surface they had crystallized, causing the snowflake-like efflorescence.
AGO curators and conservators interviewed Letendre to determine what was important to her in preserving and conserving her works, and she highlighted how important an even gloss across the surface was to her artworks, and the philosophical importance of the colour black in her paintings. These priorities guided conservation efforts, while the insights gained through scientific research will help maintain the works in the long term.
In order to restore the black paint to its intended even finish for display, conservator Meaghan Monaghan removed the white crystallization from the surface of Victoire, but it is possible that it could begin to recur. Understanding the processes that lead to this degradation will be an important tool to keep Letendre’s works in good condition.
“The world of modern paint research is complicated; each painting is unique, which is why it’s important to combine theoretical work on model paint systems with this kind of case study on actual works of art” said Helwig. The team hopes to collaborate on studying a larger cross section of Letendre’s paintings in oil and acrylic in the future to add to the body of knowledge.

Margaux Davoine has written up a teaser for the 2020 edition of ISEA in the form of an August 6, 2020 interview with Yan Breuleux. I’ve excerpted one bit,
Finally, thinking about this year’s theme [Why Sentience?], there might be something a bit ironic about exploring the notion of sentience (historically reserved for biological life, and quite a small subsection of it) through digital media and electronic arts. There’s been much work done in the past 25 years to loosen the boundaries between such distinctions: how do you imagine ISEA2020 helping in that?
The similarities shared between humans, animals, and machines are fundamental in cybernetic sciences. According to the founder of cybernetics Norbert Wiener, the main tenets of the information paradigm – the notion of feedback – can be applied to humans, animals as well as the material world. Famously, the AA predictor (as analysed by Peter Galison in 1994) can be read as a first attempt at human-machine fusion (otherwise known as a cyborg).
The infamous Turing test also tends to blur the lines between humans and machines, between language and informational systems. Second-order cybernetics are often associated with biologists Francisco Varela and Humberto Maturana. The very notion of autopoiesis (a system capable of maintaining a certain level of stability in an unstable environment) relates back to the concept of homeostasis formulated by Willam Ross [William Ross Ashby] in 1952. Moreover, the concept of “ecosystems” emanates directly from the field of second-order cybernetics, providing researchers with a clearer picture of the interdependencies between living and non-living organisms. In light of these theories, the absence of boundaries between animals, humans, and machines constitutes the foundation of the technosciences paradigm. New media, technological arts, virtual arts, etc., partake in the dialogue between humans and machines, and thus contribute to the prolongation of this paradigm. Frank Popper nearly called his book “Techno Art” instead of “Virtual Art”, in reference to technosciences (his editor suggested the name change). For artists in the technological arts community, Jakob von Uexkull’s notion of “human-animal milieu” is an essential reference. Also present in Simondon’s reflections on human environments (both natural and artificial), the notion of “milieu” is quite important in the discourses about art and the environment. Concordia University’s artistic community chose the concept of “milieu” as the rallying point of its research laboratories.
ISEA2020’s theme resonates particularly well with the recent eruption of processing and artificial intelligence technologies. For me, Sentience is a purely human and animal idea: machines can only simulate our ways of thinking and feeling. Partly in an effort to explore the illusion of sentience in computers, Louis-Philippe Rondeau, Benoît Melançon and I have established the Mimesis laboratory at NAD University. Processing and AI technologies are especially useful in the creation of “digital doubles”, “Vactors”, real-time avatar generation, Deep Fakes and new forms of personalised interactions.
I adhere to the epistemological position that the living world is immeasurable. Through their ability to simulate, machines can merely reduce complex logics to a point of understandability. The utopian notion of empathetic computers is an idea mostly explored by popular science-fiction movies. Nonetheless, research into computer sentience allows us to devise possible applications, explore notions of embodiment and agency, and thereby develop new forms of interaction. Beyond my own point of view, the idea that machines can somehow feel emotions gives artists and researchers the opportunity to experiment with certain findings from the fields of the cognitive sciences, computer sciences and interactive design. For example, in 2002 I was particularly marked by an immersive installation at Universal Exhibition in Neuchatel, Switzerland titled Ada: Intelligence Space. The installation comprised an artificial environment controlled by a computer, which interacted with the audience on the basis of artificial emotion. The system encouraged visitors to participate by intelligently analysing their movements and sounds. Another example, Louis-Philippe Demers’ Blind Robot (2012), demonstrates how artists can be both critical of, and amazed by, these new forms of knowledge. Additionally, the 2016 BIAN (Biennale internationale d’art numérique), organized by ELEKTRA (Alain Thibault) explored the various ways these concepts were appropriated in installation and interactive art. The way I see it, current works of digital art operate as boundary objects. The varied usages and interpretations of a particular work of art allow it to be analyzed from nearly every angle or field of study. Thus, philosophers can ask themselves: how does a computer come to understand what being human really is?
I have yet to attend conferences or exchange with researchers on that subject. Although the sheer number of presentation propositions sent to ISEA2020, I have no doubt that the symposium will be the ideal context to reflect on the concept of Sentience and many issues raised therein.
For the last bit of news.
HotPopRobot, one of six global winners of 2020 NASA SpaceApps COVID-19 challenge
We are excited to become the global winners of the 2020 NASA SpaceApps COVID-19 Challenge from among 2,000 teams from 150 countries. The six Global Winners will be invited to visit a NASA Rocket Launch site to view a spacecraft launch along with the SpaceApps Organizing team once travel is deemed safe. They will also receive an invitation to present their projects to NASA, ESA [European Space Agency], JAXA [Japan Aerospace Exploration Agency], CNES [Centre National D’Etudes Spatiales; France], and CSA [Canadian Space Agency] personnel. https://covid19.spaceappschallenge.org/awards
15,000 participants joined together to submit over 1400 projects for the COVID-19 Global Challenge that was held on 30-31 May 2020. 40 teams made to the Global Finalists. Amongst them, 6 teams became the global winners!
The 2020 SpaceApps was an international collaboration between NASA, Canadian Space Agency, ESA, JAXA, CSA,[sic] and CNES focused on solving global challenges. During a period of 48 hours, participants from around the world were required to create virtual teams and solve any of the 12 challenges related to the COVID-19 pandemic posted on the SpaceApps website. More details about the 2020 SpaceApps COVID-19 Challenge: https://sa-2019.s3.amazonaws.com/media/documents/Space_Apps_FAQ_COVID_.pdf
We have been participating in NASA Space Challenge for the last seven years since 2014. We were only 8 years and 5 years respectively when we participated in our very first SpaceApps 2014.
We have grown up learning more about space, tacking global challenges, making hardware and software projects, participating in meetings, networking with mentors and teams across the globe, and giving presentations through the annual NASA Space Apps Challenges. This is one challenge we look forward to every year.
It has been a fun and exciting journey meeting so many people and astronauts and visiting several fascinating places on the way! We hope more kids, youths, and families are inspired by our space journey. Space is for all and is yours to discover!
Arianne Cohen’s May 28, 2020 article for Fast Company concisely sums up the space junk problem and solution (Note: A link has been removed),
Throwing money at problems works in space, too! A paper in the Proceedings of the National Academy of Sciences [PNAS] says that the space debris problem can be fixed once and for all, not by the engineers and scientists who consider space their domain, but with cold, hard cash: about $235,000 per satellite. Such a plan would create financial barriers for smaller organizations.
This looks pretty doesn’t it? hard to believe it’s a representation of the junk yard that floats around the earth.
Space is getting crowded. Aging satellites and space debris crowd low-Earth orbit, and launching new satellites adds to the collision risk. The most effective way to solve the space junk problem, according to a new study, is not to capture debris or deorbit old satellites: it’s an international agreement to charge operators “orbital-use fees” for every satellite put into orbit.
Orbital use fees would also increase the long-run value of the space industry, said economist Matthew Burgess, a CIRES [Cooperative Institute for Research in Environmental Sciences] Fellow and co-author of the new paper. By reducing future satellite and debris collision risk, an annual fee rising to about $235,000 per satellite would quadruple the value of the satellite industry by 2040, he and his colleagues concluded in a paper published today in the Proceedings of the National Academy of Sciences.
“Space is a common resource, but companies aren’t accounting for the cost their satellites impose on other operators when they decide whether or not to launch,” said Burgess, who is also an assistant professor in Environmental Studies and an affiliated faculty member in Economics at the University of Colorado Boulder. “We need a policy that lets satellite operators directly factor in the costs their launches impose on other operators.”
Currently, an estimated 20,000 objects–including satellites and space debris–are crowding low-Earth orbit. It’s the latest Tragedy of the Commons, the researchers said: Each operator launches more and more satellites until their private collision risk equals the value of the orbiting satellite.
So far, proposed solutions have been primarily technological or managerial, said Akhil Rao, assistant professor of economics at Middlebury College and the paper’s lead author. Technological fixes include removing space debris from orbit with nets, harpoons, or lasers. Deorbiting a satellite at the end of its life is a managerial fix.
Ultimately, engineering or managerial solutions like these won’t solve the debris problem because they don’t change the incentives for operators. For example, removing space debris might motivate operators to launch more satellites–further crowding low-Earth orbit, increasing collision risk, and raising costs. “This is an incentive problem more than an engineering problem. What’s key is getting the incentives right,” Rao said.
A better approach to the space debris problem, Rao and his colleagues found, is to implement an orbital-use fee–a tax on orbiting satellites. “That’s not the same as a launch fee,” Rao said, “Launch fees by themselves can’t induce operators to deorbit their satellites when necessary, and it’s not the launch but the orbiting satellite that causes the damage.”
Orbital-use fees could be straight-up fees or tradeable permits, and they could also be orbit-specific, since satellites in different orbits produce varying collision risks. Most important, the fee for each satellite would be calculated to reflect the cost to the industry of putting another satellite into orbit, including projected current and future costs of additional collision risk and space debris production–costs operators don’t currently factor into their launches. “In our model, what matters is that satellite operators are paying the cost of the collision risk imposed on other operators,” said Daniel Kaffine, professor of economics and RASEI Fellow at the University of Colorado Boulder and co-author on the paper.
And those fees would increase over time, to account for the rising value of cleaner orbits. In the researchers’ model, the optimal fee would rise at a rate of 14 percent per year, reaching roughly $235,000 per satellite-year by 2040.
For an orbital-use fee approach to work, the researchers found, all countries launching satellites would need to participate–that’s about a dozen that launch satellites on their own launch vehicles and more than 30 that own satellites. In addition, each country would need to charge the same fee per unit of collision risk for each satellite that goes into orbit, although each country could collect revenue separately. Countries use similar approaches already in carbon taxes and fisheries management.
In this study, Rao and his colleagues compared orbital-use fees to business as usual (that is, open access to space) and to technological fixes such as removing space debris. They found that orbital use fees forced operators to directly weigh the expected lifetime value of their satellites against the cost to industry of putting another satellite into orbit and creating additional risk. In other scenarios, operators still had incentive to race into space, hoping to extract some value before it got too crowded.
With orbital-use fees, the long-run value of the satellite industry would increase from around $600 billion under the business-as-usual scenario to around $3 trillion, researchers found. The increase in value comes from reducing collisions and collision-related costs, such as launching replacement satellites.
Orbital-use fees could also help satellite operators get ahead of the space junk problem. “In other sectors, addressing the Tragedy of the Commons has often been a game of catch-up with substantial social costs. But the relatively young space industry can avoid these costs before they escalate,” Burgess said.
Scientists have long been puzzled by the existence of so-called “buckyballs” – complex carbon molecules with a soccer-ball-like structure – throughout interstellar space. Now, a team of researchers from the University of Arizona has proposed a mechanism for their formation in a study published in the Astrophysical Journal Letters.
Carbon 60, or C60 for short, whose official name is Buckminsterfullerene, comes in spherical molecules consisting of 60 carbon atoms organized in five-membered and six-membered rings. The name “buckyball” derives from their resemblance to the architectural work of Richard Buckminster Fuller [bettr known as Buckminster Fuller], who designed many dome structures that look similar to C60. Their formation was thought to only be possible in lab settings until their detection in space challenged this assumption.
For decades, people thought interstellar space was sprinkled with lightweight molecules only: mostly single atoms, two-atom molecules and the occasional nine or 10-atom molecules. This was until massive C60 and C70 molecules were detected a few years ago.
Researchers were also surprised to find that that they were composed of pure carbon. In the lab, C60 is made by blasting together pure carbon sources, such as graphite. In space, C60 was detected in planetary nebulae, which are the debris of dying stars. This environment has about 10,000 hydrogen molecules for every carbon molecule.
“Any hydrogen should destroy fullerene synthesis,” said astrobiology and chemistry doctoral student Jacob Bernal, lead author of the paper. “If you have a box of balls, and for every 10,000 hydrogen balls you have one carbon, and you keep shaking them, how likely is it that you get 60 carbons to stick together? It’s very unlikely.”
Bernal and his co-authors began investigating the C60 mechanism after realizing that the transmission electron microscope, or TEM, housed at the Kuiper Materials Imaging and Characterization Facility at UArizona, was able to simulate the planetary nebula environment fairly well.
The TEM, which is funded by the National Science Foundation and NASA, has a serial number of “1” because it is the first of its kind in the world with its exact configuration. Its 200,000-volt electron beam can probe matter down to 78 picometers – scales too small for the human brain to comprehend – in order to see individual atoms. It operates under a vacuum with extremely low pressures. This pressure, or lack thereof, in the TEM is very close to the pressure in circumstellar environments.
“It’s not that we necessarily tailored the instrument to have these specific kinds of pressures,” said Tom Zega, associate professor in the UArizona Lunar and Planetary Lab and study co-author. “These instruments operate at those kinds of very low pressures not because we want them to be like stars, but because molecules of the atmosphere get in the way when you’re trying to do high-resolution imaging with electron microscopes.”
The team partnered with the U.S. Department of Energy’s Argonne National Lab, near Chicago, which has a TEM capable of studying radiation responses of materials. They placed silicon carbide, a common form of dust made in stars, in the low-pressure environment of the TEM, subjected it to temperatures up to 1,830 degrees Fahrenheit and irradiated it with high-energy xenon ions.
Then, it was brought back to Tucson for researchers to utilize the higher resolution and better analytical capabilities of the UArizona TEM. They knew their hypothesis would be validated if they observed the silicon shedding and exposing pure carbon.
“Sure enough, the silicon came off, and you were left with layers of carbon in six-membered ring sets called graphite,” said co-author Lucy Ziurys, Regents Professor of astronomy, chemistry and biochemistry. “And then when the grains had an uneven surface, five-membered and six-membered rings formed and made spherical structures matching the diameter of C60. So, we think we’re seeing C60.”
This work suggests that C60 is derived from the silicon carbide dust made by dying stars, which is then hit by high temperatures, shockwaves and high energy particles , leeching silicon from the surface and leaving carbon behind. These big molecules are dispersed because dying stars eject their material into the interstellar medium – the spaces in between stars – thus accounting for their presence outside of planetary nebulae. Buckyballs are very stable to radiation, allowing them to survive for billions of years if shielded from the harsh environment of space.
“The conditions in the universe where we would expect complex things to be destroyed are actually the conditions that create them,” Bernal said, adding that the implications of the findings are endless.
“If this mechanism is forming C60, it’s probably forming all kinds of carbon nanostructures,” Ziurys said. “And if you read the chemical literature, these are all thought to be synthetic materials only made in the lab, and yet, interstellar space seems to be making them naturally.”
If the findings are any sign, it appears that there is more the universe has to tell us about how chemistry truly works.

There is a lot happening in the next day or two. I have two Vancouver (Canada) science events and an online event, which can be attended from anywhere.
Space debris on January 23, 2020 in Vancouver
I was surprised to learn about space debris (it was described as a floating junkyard in space) in 1992. It seems things have not gotten better. Here’s more from the Cosmic Nights: Space Debris event page on the H.R. MacMillan Space Centre website,
Cosmic Nights: Space Debris
There are tens of thousands of pieces of man-made debris, or “space junk,” orbiting the Earth that threaten satellites and other spacecraft. With the increase of space exploration and no debris removal processes in place that number is sure to increase.
Learn more about the impact space debris will have on current and future missions, space law, and the impact human activity, both scientific, and commercial are having on space as we discuss what it will take to make space exploration more sustainable. Physics professors Dr. Aaron Rosengren, and Dr. Aaron Boley will be joining us to share their expertise on the subject.

8:00pm and 9:00pm – “Space Junk: Our Quest to Conquer the Space Environment Problem” lecture by Dr. Aaron Rosengren
At the end of 2019, after nearly two decades, the U.S. government issued updated orbital debris mitigation guidelines, but the revision fell short of the sweeping changes many in the space debris research community expected. The updated guidelines sets new quantitative limits on events that can create debris and updates the classes of orbits to be used for the retirement of satellites, even allowing for the new exotic idea of passive disposal through gravitational resonances (similar phenomena have left their mark on the asteroid belt between Mars and Jupiter). The revised guidelines, however, do not make major changes, and leave intact the 25-year time frame for end-of-life disposal of low-Earth orbit satellites, a period many now believe to be far too long with the ever increasing orbital traffic in near-Earth space. In this talk, I will discuss various approaches to cleaning up or containing space junk, such as a recent exciting activity in Australia to use laser photo pressure to nudge inactive debris to safe orbits.

Canada-wide 2nd Canadian DIY Biology Summit (live audio and webcast)
This is a January 22, 2020 event accessible Canada-wide. For anyone on Pacific Time, it does mean being ready to check-in at 5 am. The first DIY Biology (‘do-it-yourself’ biology) Summit was held in 2016.
Organizers of Community Biolabs across Canada are converging on Ottawa this Wednesday for the second Canadian DIY Biology Summit organized by the Public Health Agency of Canada (PHAC). OSN [Open Science Network] President & Co-Founder, Scott Pownall, has been invited to talk about the Future of DIY/Community Biology in Canada.
A few points of clarification: DIYbio YVR has been renamed Open Science Network on Meetup and, should you wish to attend the summit virtually, there is information about passwords and codes on the agenda, which presumably will help you to get access.
Nerd Nite v. 49: Waterslides, Oil Tankers, and Predator-Prey Relationships on January 22, 2020 in Vancouver
When you were young, did you spend your summers zooming down waterslides? We remember days where our calves ached from climbing stairs, and sore bums from well… you know. And, if you were like us, you also stared at those slides and thought “How are these things made? And, is it going to disassemble while I’m on it?”. Today, we spend more of our summer days staring out at the oil tankers lining the shore, or watching seagulls dive down to retrieve waste left behind by tourists on Granville Island, but we maintain that curiousity about the things around us! So, splash into a New Year with us to learn about all three: waterslides, oil tankers, and predator-prey relationships.
Zachary is completing an MSc at UBC investigating freshwater and estuarine predation on juvenile salmon during their out-migration from natal rivers and works as a part-time contract biologist in the lower mainland.

There’s a very good November 11, 2019 article by Natalie Angier for the New York Times on carbon nanotubes (CNTs) and the colour black,
On a laboratory bench at the National Institute of Standards and Technology was a square tray with two black disks inside, each about the width of the top of a Dixie cup. Both disks were undeniably black, yet they didn’t look quite the same.
Solomon Woods, 49, a trim, dark-haired, soft-spoken physicist, was about to demonstrate how different they were, and how serenely voracious a black could be.
“The human eye is extraordinarily sensitive to light,” Dr. Woods said. Throw a few dozen photons its way, a few dozen quantum-sized packets of light, and the eye can readily track them.
Dr. Woods pulled a laser pointer from his pocket. “This pointer,” he said, “puts out 100 trillion photons per second.” He switched on the laser and began slowly sweeping its bright beam across the surface of the tray.
On hitting the white background, the light bounced back almost unimpeded, as rude as a glaring headlight in a rearview mirror.
The beam moved to the first black disk, a rondel of engineered carbon now more than a decade old. The light dimmed significantly, as a sizable tranche of the incident photons were absorbed by the black pigment, yet the glow remained surprisingly strong.
Finally Dr. Woods trained his pointer on the second black disk, and suddenly the laser’s brilliant beam, its brash photonic probe, simply — disappeared. Trillions of light particles were striking the black disk, and virtually none were winking back up again. It was like watching a circus performer swallow a sword, or a husband “share” your plate of French fries: Hey, where did it all go?
N.I.S.T. disk number two was an example of advanced ultra-black technology: elaborately engineered arrays of tiny carbon cylinders, or nanotubes, designed to capture and muzzle any light they encounter. Blacker is the new black, and researchers here and abroad are working to create ever more efficient light traps, which means fabricating materials that look ever darker, ever flatter, ever more ripped from the void.
The N.I.S.T. ultra-black absorbs at least 99.99 percent of the light that stumbles into its nanotube forest. But scientists at the Massachusetts Institute of Technology reported in September the creation of a carbon nanotube coating that they claim captures better than 99.995 of the incident light.
… The more fastidious and reliable the ultra-black, the more broadly useful it will prove to be — in solar power generators, radiometers, industrial baffles and telescopes primed to detect the faintest light fluxes as a distant planet traverses the face of its star.
Psychology and metaphors
It’s not all technical, Angier goes on to mention the psychological and metaphorical aspects,
Psychologists have gathered evidence that black is among the most metaphorically loaded of all colors, and that we absorb our often contradictory impressions about black at a young age.
Reporting earlier this year in the Quarterly Journal of Experimental Psychology, Robin Kramer and Joanne Prior of the University of Lincoln in the United Kingdom compared color associations in a group of 104 children, aged 5 to 10, with those of 100 university students.
The researchers showed subjects drawings in which a lineup of six otherwise identical images differed only in some aspect of color. The T-shirt of a boy taking a test, for example, was switched from black to blue to green to red to white to yellow. The same for a businessman’s necktie, a schoolgirl’s dress, a dog’s collar, a boxer’s gloves.
Participants were asked to link images with traits. Which boy was likeliest to cheat on the test? Which man was likely to be in charge at work? Which girl was the smartest in her class, which dog the scariest?
Again and again, among both children and young adults, black pulled ahead of nearly every color but red. Black was the color of cheating, and black was the color of cleverness. A black tie was the mark of a boss, a black collar the sign of a pit bull. Black was the color of strength and of winning. Black was the color of rage.
Then, there is the world of art,
For artists, black is basal and nonnegotiable, the source of shadow, line, volume, perspective and mood. “There is a black which is old and a black which is fresh,” Ad Reinhardt, the abstract expressionist artist, said. “Lustrous black and dull black, black in sunlight and black in shadow.”
So essential is black to any aesthetic act that, as David Scott Kastan and Stephen Farthing describe in their scholarly yet highly entertaining book, “On Color,” modern artists have long squabbled over who pioneered the ultimate visual distillation: the all-black painting.
Was it the Russian Constructivist Aleksandr Rodchenko, who in 1918 created a series of eight seemingly all-black canvases? No, insisted the American artist Barnett Newman: Those works were very dark brown, not black. He, Mr. Newman, deserved credit for his 1949 opus, “Abraham,” which in 1966 he described as “the first and still the only black painting in history.”
But what about Kazimir Malevich’s “Black Square” of 1915? True, it was a black square against a white background, but the black part was the point. Then again, the English polymath Robert Fludd had engraved a black square in a white border back in 1617.
Clearly, said Alfred H. Barr, Jr., the first director of the Museum of Modern Art, “Each generation must paint its own black square.”
Solomon and his NIST colleagues and the MIT scientists are all trying to create materials with structural colour, in this case, black. Angier goes on to discuss structural colour in nature mentioning bird feathers and spiders as examples of where you might find superblacks. For anyone unfamiliar with structural colour, the colour is not achieved with pigment or dye but with tiny structures, usually measured at the nanoscale, on a bird’s wing, a spider’s belly, a plant leaf, etc. Structural colour does not fade or change . Still, it’s possible to destroy the structures, i.e., the colour, but light and time will not have any effect since it’s the tiny structures and their optical properties which are producing the colour . (Even after all these years, my favourite structural colour story remains a Feb. 1, 2013 article, Color from Structure, by Cristina Luiggi for The Scientist magazine. For a shorter version, I excerpted parts of Luiggi’s story for my February 7, 2013 posting.)
The examples of structural colour in Angier’s article were new to me. However, there are many, many examples elsewhere,. You can find some here by using the terms ‘structural colour’ or ‘structural color’ in the blog’s search engine.
Angier’s is a really good article and I strongly recommend reading it if you have time but I’m a little surprised she doesn’t mention Vantablack and the artistic feud. More about that in a moment,
Massachusetts Institute of Technology and a ‘blacker black’
According to MIT (Massachusetts Institute of Technology), they have the blackest black. It too is courtesy of carbon nanotubes.
What you see in the above ‘The Redemption of Vanity’ was on show at the New York Stock Exchange (NYSE) from September 13 – November 29, 2019. It’s both an art piece and a demonstration of MIT’s blackest black.
With apologies to “Spinal Tap,” it appears that black can, indeed, get more black.
MIT engineers report today that they have cooked up a material that is 10 times blacker than anything that has previously been reported. The material is made from vertically aligned carbon nanotubes, or CNTs — microscopic filaments of carbon, like a fuzzy forest of tiny trees, that the team grew on a surface of chlorine-etched aluminum foil. The foil captures at least 99.995 percent* of any incoming light, making it the blackest material on record.
The researchers have published their findings today in the journal ACS-Applied Materials and Interfaces. They are also showcasing the cloak-like material as part of a new exhibit today at the New York Stock Exchange, titled “The Redemption of Vanity.”
The artwork, conceived by Diemut Strebe, an artist-in-residence at the MIT Center for Art, Science, and Technology, in collaboration with Brian Wardle, professor of aeronautics and astronautics at MIT, and his group, and MIT Center for Art, Science, and Technology artist-in-residence Diemut Strebe, features a 16.78-carat natural yellow diamond from LJ West Diamonds, estimated to be worth $2 million, which the team coated with the new, ultrablack CNT material. The effect is arresting: The gem, normally brilliantly faceted, appears as a flat, black void.
Wardle says the CNT material, aside from making an artistic statement, may also be of practical use, for instance in optical blinders that reduce unwanted glare, to help space telescopes spot orbiting exoplanets.
“There are optical and space science applications for very black materials, and of course, artists have been interested in black, going back well before the Renaissance,” Wardle says. “Our material is 10 times blacker than anything that’s ever been reported, but I think the blackest black is a constantly moving target. Someone will find a blacker material, and eventually we’ll understand all the underlying mechanisms, and will be able to properly engineer the ultimate black.”
Wardle’s co-author on the paper is former MIT postdoc Kehang Cui, now a professor at Shanghai Jiao Tong University.
Into the void
Wardle and Cui didn’t intend to engineer an ultrablack material. Instead, they were experimenting with ways to grow carbon nanotubes on electrically conducting materials such as aluminum, to boost their electrical and thermal properties.
But in attempting to grow CNTs on aluminum, Cui ran up against a barrier, literally: an ever-present layer of oxide that coats aluminum when it is exposed to air. This oxide layer acts as an insulator, blocking rather than conducting electricity and heat. As he cast about for ways to remove aluminum’s oxide layer, Cui found a solution in salt, or sodium chloride.
At the time, Wardle’s group was using salt and other pantry products, such as baking soda and detergent, to grow carbon nanotubes. In their tests with salt, Cui noticed that chloride ions were eating away at aluminum’s surface and dissolving its oxide layer.
“This etching process is common for many metals,” Cui says. “For instance, ships suffer from corrosion of chlorine-based ocean water. Now we’re using this process to our advantage.”
Cui found that if he soaked aluminum foil in saltwater, he could remove the oxide layer. He then transferred the foil to an oxygen-free environment to prevent reoxidation, and finally, placed the etched aluminum in an oven, where the group carried out techniques to grow carbon nanotubes via a process called chemical vapor deposition.
By removing the oxide layer, the researchers were able to grow carbon nanotubes on aluminum, at much lower temperatures than they otherwise would, by about 100 degrees Celsius. They also saw that the combination of CNTs on aluminum significantly enhanced the material’s thermal and electrical properties — a finding that they expected.
What surprised them was the material’s color.
“I remember noticing how black it was before growing carbon nanotubes on it, and then after growth, it looked even darker,” Cui recalls. “So I thought I should measure the optical reflectance of the sample.
“Our group does not usually focus on optical properties of materials, but this work was going on at the same time as our art-science collaborations with Diemut, so art influenced science in this case,” says Wardle.
Wardle and Cui, who have applied for a patent on the technology, are making the new CNT process freely available to any artist to use for a noncommercial art project.
“Built to take abuse”
Cui measured the amount of light reflected by the material, not just from directly overhead, but also from every other possible angle. The results showed that the material absorbed at least 99.995 percent of incoming light, from every angle. In other words, it reflected 10 times less light than all other superblack materials, including Vantablack. If the material contained bumps or ridges, or features of any kind, no matter what angle it was viewed from, these features would be invisible, obscured in a void of black.
The researchers aren’t entirely sure of the mechanism contributing to the material’s opacity, but they suspect that it may have something to do with the combination of etched aluminum, which is somewhat blackened, with the carbon nanotubes. Scientists believe that forests of carbon nanotubes can trap and convert most incoming light to heat, reflecting very little of it back out as light, thereby giving CNTs a particularly black shade.
“CNT forests of different varieties are known to be extremely black, but there is a lack of mechanistic understanding as to why this material is the blackest. That needs further study,” Wardle says.
The material is already gaining interest in the aerospace community. Astrophysicist and Nobel laureate John Mather, who was not involved in the research, is exploring the possibility of using Wardle’s material as the basis for a star shade — a massive black shade that would shield a space telescope from stray light.
“Optical instruments like cameras and telescopes have to get rid of unwanted glare, so you can see what you want to see,” Mather says. “Would you like to see an Earth orbiting another star? We need something very black. … And this black has to be tough to withstand a rocket launch. Old versions were fragile forests of fur, but these are more like pot scrubbers — built to take abuse.”
[Note] An earlier version of this story stated that the new material captures more than 99.96 percent of incoming light. That number has been updated to be more precise; the material absorbs at least 99.995 of incoming light.
Here’s an August 29, 2019 news release from MIT announcing the then upcoming show. Usually I’d expect to see a research paper associated with this work but this time it seems to an art exhibit only,
The MIT Center for Art, Science &Technology (CAST) and the New York Stock Exchange (NYSE) will present The Redemption of Vanity,created by artist Diemut Strebe in collaboration with MIT scientist Brian Wardle and his lab, on view at the New York Stock Exchange September 13, 2019 -November 25, 2019. For the work, a 16.78 carat natural yellow diamond valued at $2 million from L.J.West was coated using a new procedure of generating carbon nanotubes (CNTs), recently measured to be the blackest black ever created, which makes the diamond seem to disappear into an invisible void. The patented carbon nanotube technology (CNT) absorbs more than 99.96% of light and was developed by Professor Wardle and his necstlablab at MIT.
“Any object covered with this CNT material loses all its plasticity and appears entirely flat, abbreviated/reduced to a black silhouette. In outright contradiction to this we see that a diamond,while made of the very same element (carbon) performs the most intense reflection of light on earth.Because of the extremely high light absorbtive qualities of the CNTs, any object, in this case a large diamond coated with CNT’s, becomes a kind of black hole absent of shadows,“ explains Strebe.“The unification of extreme opposites in one object and the particular aesthetic features of the CNTs caught my imagination for this art project.”
“Strebe’s art-science collaboration caused us to look at the optical properties of our new CNT growth, and we discovered that these particular CNTs are blacker than all other reported materials by an order of magnitude across the visible spectrum”, says Wardle. The MIT team is offering the process for any artist to use. “We do not believe in exclusive ownership of any material or idea for any artwork and have opened our method to any artist,” say Strebe and Wardle.“
The project explores material and immaterial value attached to objects and concepts in reference to luxury, society and to art. We are presenting the literal devaluation of a diamond, which is highly symbolic and of high economic value.It presents a challenge to art market mechanisms on the one hand, while expressing at the same time questions of the value of art in a broader way. In this sense it manifests an inquiry into the significance of the value of objects of art and the art market,” says Strebe. “We are honored to present this work at The New York Stock Exchange, which I believe to be a most fitting location to consider the ideas embedded in The Redemption of Vanity.”
“The New York Stock Exchange, a center of financial and technological innovation for 227 years, is the perfect venue to display Diemut Strebe and Professor Brian Wardle’s collaboration. Their work brings together cutting-edge nanotube technology and a natural diamond, which is a symbol of both value and longevity,” said John Tuttle, NYSE Group Vice Chairman & Chief Commercial Officer.
“We welcome all scientists and artists to venture into the world of natural color diamonds. The Redemption of Vanity exemplifies the bond between art, science, and luxury. The 16-carat vivid yellow diamond in the exhibit spent millions of years in complete darkness, deep below the earth’s surface. It was only recently unearthed —a once-in-a-lifetime discovery of exquisite size and color. Now the diamond will relive its journey to darkness as it is covered in the blackest of materials. Once again, it will become a reminder that something rare and beautiful can exist even in darkness,”said Larry West.
The “disappearing” diamond in The Redemption of Vanity is a $2 Million Fancy Vivid Yellow SI1 (GIA), Radiant shape, from color diamond specialist, L.J. West Diamonds Inc. of New York.
The Redemption of Vanity, conceived by Diemut Strebe, has been realized with Brian L. Wardle, Professor of Aeronautics and Astronautics and Director of necstlab and Nano-Engineered Composite aerospace STructures (NECST) Consortium and his team Drs. Luiz Acauan and Estelle Cohen, in conjunction with Strebe’s residency at MIT supported by the Center for Art, Science & Technology (CAST).

An artistic feud (of sorts)
Earlier this year, I updated a story on Vantablack. It was the blackest black, blocking 99.8% of light when I featured it in a March 14, 2016 posting. The UK company making the announcement, Surrey NanoSystems, then laid the groundwork for an artistic feud when it granted exclusive rights to their carbon nanotube-based coating, Vantablack, to Sir Anish Kapoor mentioned here in an April 16, 2016 posting.
This exclusivity outraged some artists notably, Stuart Semple. In his first act of defiance, he created the pinkest pink. Next, came a Kickstarter campaign to fund Semple’s blackest black, which would be available to all artists except Anish Kapoor. You can read all about the pinkest pink and blackest black as per Semple in my February 21, 2019 posting. You can also get a bit of an update in an Oct. 17, 2019 Stuart Semple proffile by Berenice Baker for Verdict,
… so I managed to hire a scientist, Jemima, to work in the studio with me. She got really close to a super black, and we made our own pigment to this recipe and it was awesome, but we couldn’t afford to put it into manufacture because it cost £25,000.”
Semple launched a Kickstarter campaign and was amazed to raise half a million pounds, making it the second most-supported art Kickstarter of all time.
The ‘race to the blackest’ is well underway, with MIT researchers recently announcing a carbon nanotube-based black whose light absorption they tested by coasting a diamond. But Semple is determined that his black should be affordable by all artists and work like a paint, not only perform in laboratory conditions. He’s currently working with Jemima and two chemists to upgrade the recipe for Black 3.2.
I don’t know how Semple arrived at his blackest black. I think it’s unlikely that he achieved the result by working with carbon nanotubes since my understanding is that CNTs aren’t that easy to produce.
Interesting, eh? In just a few years scientists have progressed from achieving a 99.8% black to 99.999%. It doesn’t seem like that big a difference to me but with Solomon Woods, at the beginning of this post, making the point that our eyes are very sensitive to light, an artistic feud, and a study uncovering deep emotions, getting the blackest black is a much more artistically fraught endeavour than I had imagined.
I don’t know what’s happened but either there are way more science type events or I’ve changed some pattern of internet use and am stumbling across more of them. I vote for the former.
In any event, this is the third ’roundup’ of science type things and/or events that I’ve published this October 2019. *ETA October 23, 2019: The events are in one or other of the science museums in Ottawa, the internships (part-time) are in Washington, DC, and Sci_Tunes is aimed at teachers in the UK although I imagine anyone is free to enjoy them.*
All three of the museums that are included in the Ingenium portmanteau (formerly the Canada Science and Technology Museums Corporation) have events and Ingenium itself is announcing a science type thing (a video game).
AI (artificial intelligence) and climate change at the Canada Museum of Science and Technology
From an October 16, 2019 Ingenium announcement (received via email),
Canada Science and Technology Museum Oct. 24, 2019 (6:30 p.m. – 8:30 p.m.) Fee: $10 for non-members, $7 for members and students. Registration required. Language: English presentation with simultaneous translation into French, and a bilingual Q & A.
Climate Change and Artificial Intelligence – two topics essential to the future of our society, each with their own inherent challenges. What if they could work together for the greater good?
Join invited speakers from Watergeeks.io and BluWave AI for a discussion that will explore the potential to use AI to reduce greenhouse gas emissions, build climate resilience,and help Canada lead in the clean tech economy. Don’t miss this essential evening, the first in the thematic series “Living in the Machine Age.”
For anyone who may be confused about the museum name (as I was for so very long): The corporation is the governing entity for three museums, Canada Science and Technology, Canada Agriculture and Food Museum, and Canada Aviation and Space Museum. Changing the corporate name from Canada Science and Technology Museums Corporation to Ingenium was welcome news (to me, if no one else).

StarBlox Inc. is a mashup of a puzzler and a brawler — in space! Ingenium’s experts worked on the science in the game to immerse players in a realistic world. For example, when playing on the Jovian moon Io, you’ll need to dodge waves of lava. In real life, these can measure over 50 km high!
The game includes 72 unlockable photobook entries about the planets, moons, and asteroids in the game, with images from NASA. Check out the StarBlox Inc. trailer.
I’ve included a copy of the trailer here,
It seems more like a entrepreneur’s starter kit than a game. The overarching theme seems to be that the business of transportation and delivery is a zero sum game. Philosophically, they seem to be espousing capitalism as a form of the ‘strongest survive’ tenet.
OTTAWA, ON, September 30, 2019 – Nintendo Switch players can now join the team at StarBlox Incorporated – where sorting cargo is a contact sport!

Hercules and the last straw at the Canada Agriculture and Food Museum
From an October 21, 2019 Ingenium announcement (received via email),
Hercules and The Last Straw
Friday, November 8, 2019 5:30 p.m. to 8 p.m. Canada Agriculture and Food Museum
We are pleased to invite you to join us at the Canada Agriculture and Food Museum at 5:30 p.m. on Friday, November 8, 2019 for a special evening of art and inspiration.
Ingenium is thrilled to partner with celebrated artist Elaine Goble as she shares her artistic perspectives on the fascinating connection between the STEAM subjects of Science, Technology, Engineering, Arts, and Mathematics, and personal wellness. The Canada Agriculture and Food Museum is one of three museums of Ingenium – Canada’s Museums of Science and Innovation.
For the first time, three of Ms. Goble’s large-sized animal portraits will be on view simultaneously. The vernissage and presentation will be held in the museum’s Learning Centre, where guests will be welcome to view the artworks and meet the artist before the presentation. Ms. Goble’s pieces will be complemented by several other agriculture-related artworks from Ingenium’s national science and technology collection.
Light refreshments and a cash bar will be offered.
In honour of Ms. Goble’s commitment to using art as a catalyst for curiosity and expression, a $20 donation to the museum’s art programming is requested. A tax receipt will be issued to all ticket holders and donors. If you cannot attend but would like to make a donation, please visit the Ingenium Foundation’s website .
Please RSVP using this link before November 3. As space for this event is limited, please reserve early to ensure you don’t miss out on this evening devoted to art, ingenuity, and the human spirit. A reminder with more information, including detailed driving and parking directions, will be emailed to all registrants several days before the event.
Here’s the image they’re using to accompany the publicity for the event,
Presumably, that is either Hercules or a stand-in for him.
Perimeter Institute and ‘Homes away from home’ with Elizabeth Tasker
I tried but these Perimeter Institute (PI) events are very popular and they are already at the wait list stage mere hours after making tickets available. However, there are other ways to attend as you’ll see.
Here’s more from an October 18, 2019 announcement from PI (received via email),
Homes away from home WEDNESDAY, NOVEMBER 6  at 7 PM ET Elizabeth Tasker, Japan Aerospace Exploration Agency
Since the discovery of the first exoplanets in the early 1990s, we have detected more than 4,000 worlds beyond our solar system. Many of these are similar in size to our Earth, leading to an obvious question: could any be habitable?
On November 6 , astrophysicist and author Elizabeth Tasker will take audiences for a speculative stroll through a few of the alien worlds we’ve discovered in the galaxy, and ponder whether someone else may already call them home. Read more ➞

Title: Homes away from home – the hunt for habitable planets
Since the discovery of the first exoplanets in the early 1990s, we have detected more than 4,000 worlds beyond our solar system. Many of these are similar in size to our Earth, leading to an obvious question: could any be habitable?
For now, we typically only know the size and orbit of these planets, but nothing about their surface conditions. Although we cannot know for sure if these worlds could support life, we can use models to speculate on what we might find there.
In her Nov. 6  talk at Perimeter Institute, astrophysicist and author Elizabeth Tasker will take audiences for a speculative stroll through a few of the alien worlds we’ve discovered in the galaxy, and ponder whether someone else may already call them home.
Elizabeth Tasker is an astrophysicist at the Japan Aerospace Exploration Agency (JAXA). Her research explores the formation of stars and planets using computer simulations. She is particularly interested in how diverse planets might be and what different conditions might exist beyond our Solar System. Elizabeth is also a keen science communicator and writer for the NASA NExSS “Many Worlds” online column. Her popular science book, The Planet Factory, was published out in paperback in Canada last April.
Wilson Center Spring 2020 science and technology internships
From an October 21, 2019 Wilson Center announcement (received via email),
The Science and Technology Innovation Program (STIP) is currently welcoming applicantions for the spring semester of 2020. Our internships are designed to provide the opportunity for current students or recent graduates for practical experience in an environment that successfully combines scholarship with public policy. We recommend exploring our website to determine if your research interests align with current STIP programming around emerging technologies, i.e.:
5G * Artificial Intelligence * Big Data * Citizen Science * Cybersecurity * Disinformation * Marine Debris/Ocean Plastics * One Health * Open Science * Public Communication of Science * Serious Games
We offer two types of internships: graduate-level research and undergraduate-level research internships. All internships must be served in Washington, D.C. and cannot be served remotely. Internships are unpaid unless otherwise stated.
Tools like Foldscope, a $1 microscope, and Arduino, a microprocessor for creating customized scientific instrumentation, show how low cost hardware (including open, proprietary, and mixed solutions) can accelerate research while making it more transparent and participatory.
These tools have the potential to change how, and by whom, science is done, within professional spaces and broader communities. But more work is needed to understand the capacity and future potential for low-cost hardware to accelerate and broaden participation in scientific research. We are seeking a research intern with an interest in exploring democratized scientific research and technological development through the lens of low cost hardware.
Our world is drowning in plastic pollution. Humans produce about 300 million tons of plastic waste every year, equivalent to the weight of the entire human population in 2018. Nowhere is this crisis more visible than in our oceans, which by 2050 could contain more plastic than fish. Further complicating this issue are city-state actors, such as the United States, EU and China, who have vastly different approaches in how to negate the issue area. The global public needs to understand the impact of plastic pollution and how to end its leakage into the ocean.
We are seeking a research intern with an interest in exploring the ocean plastics issue in a shared role between the China Environment Forum and Science and Technology Innovation Program’s Serious Games Initiative.
The deadline for Spring 2020 internships is November 15, 2019.
Cosmic Shambles and Sci-Tunes
Cosmic Shambles (officially, The Cosmic Shambles Network) is a science blog network that rose from the ashes of the Guardian science blog network. These days they have podcasts, videos, blogs, and more. This latest project is described in an October 21, 2019 posting on the Cosmic Shambles blog,
In association with The Stephen Hawking Foundation and science troubadour Jonny Berliner, The Cosmic Shambles Network is proud to present Sci-Tunes.
Coming soon, a series of educational music videos on GCSE [General Certificate of Secondary Education examinations in the UK] Physics, written and performed by Jonny Berliner, funded by The Stephen Hawking Foundation, and produced by The Cosmic Shambles Network. The full videos will be released in November  and accompanied by free resources packs for both teachers and students. …
Researchers at RMIT University [Ausralia] have engineered a new type of transistor, the building block for all electronics. Instead of sending electrical currents through silicon, these transistors send electrons through narrow air gaps, where they can travel unimpeded as if in space.
The device unveiled in material sciences journal Nano Letters (“Metal–Air Transistors: Semiconductor-free field-emission air-channel nanoelectronics”), eliminates the use of any semiconductor at all, making it faster and less prone to heating up.
Lead author and PhD candidate in RMIT’s Functional Materials and Microsystems Research Group, Ms Shruti Nirantar, said this promising proof-of-concept design for nanochips as a combination of metal and air gaps could revolutionise electronics.
“Every computer and phone has millions to billions of electronic transistors made from silicon, but this technology is reaching its physical limits where the silicon atoms get in the way of the current flow, limiting speed and causing heat,” Nirantar said.
“Our air channel transistor technology has the current flowing through air, so there are no collisions to slow it down and no resistance in the material to produce heat.”
The power of computer chips – or number of transistors squeezed onto a silicon chip – has increased on a predictable path for decades, roughly doubling every two years. But this rate of progress, known as Moore’s Law, has slowed in recent years as engineers struggle to make transistor parts, which are already smaller than the tiniest viruses, smaller still.
Nirantar says their research is a promising way forward for nano electronics in response to the limitation of silicon-based electronics.
“This technology simply takes a different pathway to the miniaturisation of a transistor in an effort to uphold Moore’s Law for several more decades,” Shruti said.
Research team leader Associate Professor Sharath Sriram said the design solved a major flaw in traditional solid channel transistors – they are packed with atoms – which meant electrons passing through them collided, slowed down and wasted energy as heat.
“Imagine walking on a densely crowded street in an effort to get from point A to B. The crowd slows your progress and drains your energy,” Sriram said.
“Travelling in a vacuum on the other hand is like an empty highway where you can drive faster with higher energy efficiency.”
But while this concept is obvious, vacuum packaging solutions around transistors to make them faster would also make them much bigger, so are not viable.
“We address this by creating a nanoscale gap between two metal points. The gap is only a few tens of nanometers, or 50,000 times smaller than the width of a human hair, but it’s enough to fool electrons into thinking that they are travelling through a vacuum and re-create a virtual outer-space for electrons within the nanoscale air gap,” he said.
The nanoscale device is designed to be compatible with modern industry fabrication and development processes. It also has applications in space – both as electronics resistant to radiation and to use electron emission for steering and positioning ‘nano-satellites’.
“This is a step towards an exciting technology which aims to create something out of nothing to significantly increase speed of electronics and maintain pace of rapid technological progress,” Sriram said.
It’s been a while since I’ve received any notices about upcoming talks from the local Café Scientifique crowd but on May 22, 2019 there was this announcement in an email,
Dear Café Scientifiquers,
Our next café will happen on TUESDAY, MAY 28TH  at 7:30PM in the back room at YAGGER’S DOWNTOWN (433 W Pender). Our speaker for the evening will be DR. CATHERINE JOHNSON from the Department of Earth, Ocean and Atmospheric Sciences at UBC [University of British Columbia] .
GETTING TO THE HEART OF MARS WITH INSIGHT
Catherine Johnson is a professor of geophysics in the Dept of Earth, Ocean and Atmospheric Sciences at UBC Vancouver [campus], and a senior scientist at the Planetary Science Institute, Tucson. She is a Co-Investigator on the InSight mission to Mars, the OSIRIS-REx mission to asteroid Bennu and was previously a Participating Scientist on the MESSENGER mission to Mercury.
We hope to see you there!
I did some digging and found two articles about Johnson, the InSight mission, and Mars. The first one is an October 21, 2012 article by James Keller on the Huffington Post Canada website,
As NASA’s Curiosity rover beams back photos of the rocky surface of Mars, another group of scientists, including one from British Columbia, is preparing the next mission to uncover what’s underneath.
Prof. Catherine Johnson, of the University of British Columbia, is among the scientists whose project, named Insight, was selected by NASA this week as part of the U.S. space agency’s Discovery program, which invites proposals from within the scientific community.
Insight will send a stationary robotic lander to Mars in 2016, drilling down several metres into the surface as it uses a combination of temperature readings and seismic measurements to help scientists on this planet learn more about the Martian core.
The second one is a May 6, 2018 article (I gather it took them longer to get to Mars than they anticipated in 2012) by Ivan Semeniuk for the Globe and Mail newspaper website,
Thanks to a thick bank of predawn fog, Catherine Johnson couldn’t see the rocket when it blasted off early Saturday morning at the Vandenberg Air Force Base in California – but she could hear the roar as NASA’s InSight mission set off on its 6½-month journey to Mars.
“It was really impressive,” said Dr. Johnson, a planetary scientist at the University of British Columbia and a member of the mission’s science team. Describing the mood at the launch as a mixture of relief and joy, Dr. Johnson added that “the spacecraft is finally en route to do what we have worked toward for many years.”
But while InSight’s mission is just getting under way, it also marks the last stage in a particularly fruitful period for the U.S. space agency’s Mars program. In the past two decades, multiple, complementary spacecraft tackled different aspects of Mars science.
Unlike the Curiosity rover, which landed on Mars nearly six years ago and is in the process of climbing a mountain in the middle of an ancient crater, InSight is designed to stay in one place after it touches down Nov. 26 . Its purpose is to open a new direction in Mars exploration – one that leads straight down as the spacecraft deploys a unique set of instruments to spy on the planet’s interior.
“What we will learn … will help us understand the earliest history of rocky planets, including Earth,” Dr. Johnson said.
It has been a prolonged voyage to the red planet. In 2015, technical problems forced program managers to postpone InSight’s launch for 2½ years. Now, scientists are hoping for smooth sailing to Mars and an uneventful landing a few hundred kilometres north of Curiosity, at a site that Dr. Johnson cheerfully describes as “boring.”
Does the timing of this talk mean you’ll be getting the latest news since InSight landed on Mars roughly six months ago? One can only hope. Finally, Johnson’s UBC bio webpage is here.
Baba Brinkman brings us up-to-date
Here’s most of a May 22, 2019 newsletter update (received via email) from former Vancouverite and current rapper, playwright, and science communicator, Baba Brinkman,
… Over the past five years I have been collaborating frequently with a company in California called SpectorDance, after the artistic director Fran Spector Atkins invited me to write and perform a rap soundtrack to one of her dance productions. Well, a few weeks ago we played our biggest venue yet with our latest collaborative show, Ocean Trilogy, which is all about the impact of human activities including climate change on marine ecosystems. The show was developed in collaboration with scientists at the Monterey Bay Aquarium Research Institute, and for the first time there’s now a full video of the production online. Have you ever seen scientifically-informed eco rap music combined in live performance with ballet and modern dance? Enjoy.
Speaking of “Science is Everywhere”, about a year ago I got to perform my song “Can’t Stop” about the neurobiology of free will for a sold-out crowd at the Brooklyn Academy of Music alongside physicist Brian Greene, comedian Chuck Nice, and Neil deGrasse Tyson. The song is half scripted and half freestyle (can you tell which part is which?) They just released the video.
Over the past few months I’ve been performing Rap Guide to Evolution, Consciousness, and Climate Chaos off-Broadway 2-3 times per week, which has been a roller coaster. Some nights I have 80 people and it’s rocking, other nights I step on stage and play to 15 people and it takes effort to keep it lively. But since this is New York, occasionally when there’s only 15 people one of them will turn out to be a former Obama Administration Energy Advisor or will publish a five star review, which keeps it exciting.
What’s Rap Guide to Culture about? Cultural evolution and the psychology of norms of course. I recently attended a conference at the National Institute for Mathematical and Biological Synthesis in Knoxville, TN where I performed a sneak preview and did a “Rap Up” of the various conference talks, summarizing the scientific content at the end of the day, check out the video.
Okay, time to get back to packing and hit the road. More to come soon, and wish me luck continuing to dominate my lonely genre.
Brinkman has been featured here many times (just use his name as the term in the blog’s search engine). While he lives in New York City these days, he does retain a connection to Vancouver in that his mother Joyce Murray is the Member of Parliament for Vancouver Quadra and, currently, the president of the Treasury Board.
