News from the Canadian Light Source (CLS), Canadian Science Policy Conference (CSPC) 2020, the International Symposium on Electronic Arts (ISEA) 2020, and HotPopRobot

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.

The preliminary programme can be found here. This year there will be some discussion of a Canadian synthetic biology roadmap, presentations on various Indigenous concerns (mostly health), a climate challenge presentation focusing on Mexico and social vulnerability and another on parallels between climate challenges and COVID-19. There are many presentations focused on COVID-19 and.or health.

There doesn’t seem to be much focus on cyber security and, given that we just lost two ice caps (see Brandon Spektor’s August 1, 2020 article [Two Canadian ice caps have completely vanished from the Arctic, NASA imagery shows] on the Live Science website), it’s surprising that there are no presentations concerning the Arctic.

International Symposium on Electronic Arts (ISEA) 2020

According to my latest information, the early bird rate for ISEA 2020 (Oct. 13 -18) ends on August 13, 2020. (My June 22, 2020 posting describes their plans for the online event.)

You can find registration information here.

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

I last wrote about HotPopRobot’s (Artash and Arushi with a little support from their parents) response to the 2020 NASA (US National Aeronautics and Space Administration) SpaceApps challenge in my July 1, 2020 post, Toronto COVID-19 Lockdown Musical: a data sonification project from HotPopRobot. (You’ll find a video of the project embedded in the post.)

Here’s more news from HotPopRobot’s August 4, 2020 posting (Note: Links have been removed),

Artash (14 years) and Arushi (10 years). Toronto.

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!

If you have the time, I recommend reading HotPopRobot’s August 4, 2020 posting in its entirety.

Science Slam on November 29, 2019 and Collider Cafe: Art. Science. Analogies. on December 4, 2019 in Vancouver, Canada

Starting in date order:

Science Slam in Vancouver on November 29, 2019

I first featured science slams in a July 17, 2013 posting when they popped up in the UK although I think they originated in Germany. As for Science Slam Canada, I think they started in 2016, (t least, that’s when they started their twitter feed).

As for the upcoming event, here’s more from Science Slam Vancouver’s event page (on the ‘at all events in’ website),

Science Slam YVR at Fox
It’s beginning to look a lot like … it’s time to have another Science Slam at the Fox!

For those of you who have never experienced the wonder of Science Slam, welcome! We are Vancouver’s most epic science showdown. Sit back, relax, and watch as our competitors battle to achieve science communication fame and glory.

What exactly is a science slam? Based on the format of a poetry slam, a science slam is a competition where speakers gather to share their science with you – the audience. Competitors have five minutes to present on any science topic without the use of a slideshow and are judged based on communication skills, audience impact and scientific content. Props and creative presentation styles are encouraged!

Whether you’re a researcher, student, educator, artist, or communicator, our stage is open to you. If you’ve got a science topic you’re researching, or just a topic you’re excited about, send in an application! If you’re not sure about an idea, just ask!

Collider Cafe in Vancouver on December 4, 2019

I think they were tired when they (CuriosityCollider.org) came up with the title for the upcoming Collider Cafe December 2019 event. Unfortunately, the description isn’t too exciting either. On the plus side, their recent Invasive Systems Collisions Festival was pretty interesting and one of the exhibits from that festival is being featured (artist: Laara Cerman; scientist: Scott Pownell)..

Here’s more about the upcoming Collider Cafe from their November 27, 2019 announcement (received via email),

Art. Science. Analogies.

Let analogies guide us through exploring the art and science in chemistry, nature, genetics, and technology.

Our #ColliderCafe is a space for artists, scientists, makers, and anyone interested in art+science to meet, discover, and connect. Are you curious? Join us at “Collider Cafe: Art. Science. Analosiges.” to explore how art and science intersect in the exploration of curiosity.

When: 8:00pm on Wednesday, December 4, 2019. Doors open at 7:30pm.
Where: Pizzeria Barbarella. 654 E Broadway, Vancouver, BC (Google Map).
Cost: $5-10 (sliding scale) cover at the door. Proceeds will be used to cover the cost of running this event, and to fund future Curiosity Collider events.

//Special thanks to Pizzeria Barbarella for hosting the upcoming Collider Cafe!//

With speakers:
Vance Williams (Chemistry) – Crystalline Landscapes
Laara Cerman (Art & Nature) and Scott Pownell (Genetics) – Flora’s Song (DNA Sonification)
Chris Dunnett (Multidisciplinary Art) – Poetry of Technology

Plus, interact with Laara and Scott’s work “Flora’s Song No. 1 in C Major” – a hand-cranked music box that plays a tune created from the DNA of local invasive plants.

Also, CC Creative Director Char Hoyt will share highlights from our annual art-science festival Collisions Festival: Invasive Systems.

Head to the Facebook event page – let us know you are coming and share this event with others! Follow updates on Instagram via @curiositycollider or #ColliderCafe. 

Back to me, I’m still struggling with this hugely changed Word Press, which they claim is an ‘improvement’. In any case, for this second event, I decided that choosing a larger font size was superior to putting everything into a single block as I did for the Science Slam event. Please let me know if you have any opinions on the matter in the comments section.

Moving on, don’t expect Chris Dunnett’s presentation ‘Poetry of Technology’ to necessarily feature any poetry, if his website is any indication of his work. Also, I notice that Vance Williams is associated with 4D Labs at Simon Fraser University. At one time, 4D Labs was a ‘nanotechnology’ lab but at this time (November 29, 2019), it seems they are a revenue-producing group selling their materials expertise and access to their lab equipment to industry and other academic institutions. Still, Williams may feature some nanoscale work as part of his presentation.

Bill Nye saving science ?; a Blackout Night Sky Festival; and Eclipse: Total Alignment (science events in Vancouver Canada)

During August (2017), science in Vancouver (Canada) seems to be mostly about the night sky. The one exception is an event featuring American science communicator, Bill Nye. Here, in the order in which they occur, are the three science events mentioned in the head (scroll down to the third event [Eclipse: Total Alignment] if you are interested in Early Bird tickets, which are available until Aug. 4, 2017).

Bill Nye speaks

Billed as ‘An Evening With Bill Nye & George Stroumboulopoulos’, the event takes place at the Orpheum Theatre on Friday, August 11, 2017. Here’s more from the event page on brownpapertickets.com,

An Evening With Bill Nye & George Stroumboulopoulos
presented by Pangburn Philosophy

Friday, August 11, 2017
Doors: 7pm
Show: 8pm Sharp!

Bill Nye is one of the worlds most eminent promoters of science. He is a scientist, engineer, comedian, author, and inventor. His mission: to help foster a scientifically literate society, to help people everywhere understand and appreciate the science that makes our world work. Making science entertaining and accessible is something Bill has been doing most of his life. He will grace the stage on August 11th at the Orpheum Theatre in Vancouver to exchange dialogue with one of Canada’s most beloved public figures and tv personalities. George Stroumboulopoulos is a six-time Gemini Award and Canadian Screen Award winner for best host in a talk series, George Stroumboulopoulos has interviewed a who’s who of entertainment icons, world leaders and respected thinkers. George has also taken an active role in global initiatives and is a strong advocate for social issues.Special Note:

All PREMIUM ticket purchases grant you a copy of Bill Nye’s new book “Everything All at Once” plus fast-pass access to Bill’s book signing, taking place directly after the event.

All STUDENT discounted tickets are Will Call only at the Box Office, on the evening of the event. Student & Photo ID must be shown. No exceptions.

Service Charges Disclaimer
Note that all tickets are subject to an additional $3.50 for the Facility Fee and $5.00 for the Ticketing Fee.
Friday Aug 11, 2017 8:00 PM – Friday Aug 11, 2017 11:00 PM | CA$60.00 – CA$150.00

I got a message saying ‘sales are ended’, which suggests the event is sold out but organizers usually trumpet that detail right away so I don’t know. It might be an idea to try the Buy Tickets button on this page for yourself.

For anyone unfamiliar with the event organizers, Pangburn Philosophy, there’s their home page and this video,

While I’m quite interested in science and art, singly and together, the discussion about science, religion, and/or god, discussed in the video, leaves me cold. I notice the Pangburn Philosophy organization has a series of events titled ‘Science and Reason’ and all of them feature Richard Dawkins who (as I understand it) has been very involved in the debate about science/reason and religion/god. The debate gets more attention in the UK than it has here in Canada.

Getting back to Bill Nye, there was a provocative essay about Nye, his new television programme, and the debate regarding science/reason and anti-science/alternative facts (which can also touch on religion/god). From an April 25, 2017 essay (titled: Can Bill Nye – or any other science show – really save the world?) by Heather Akin, Bruce W. Hardy, Dietram A. Scheufele, and Dominique Brossard for The Conversation.com (h/t May 1, 2017 republication on salon.com; Note: Links have been removed)

Netflix’s new talk show, “Bill Nye Saves the World,” debuted the night before people around the world joined together to demonstrate and March for Science. Many have lauded the timing and relevance of the show, featuring the famous “Science Guy” as its host, because it aims to myth-bust and debunk anti-scientific claims in an alternative-fact era.

But are more facts really the kryptonite that will rein in what some suggest is a rapidly spreading “anti-science” sentiment in the U.S.?

“With the right science and good writing,” Nye hopes, “we’ll do our best to enlighten and entertain our audience. And, perhaps we’ll change the world a little.” In an ideal world, a show like this might attract a broad and diverse audience with varying levels of science interest and background. By entertaining a wide range of viewers, the thinking goes, the show could effectively dismantle enduring beliefs that are at odds with scientific evidence. Significant parts of the public still aren’t on board with the scientific consensus on climate change and the safety of vaccines and genetically modified foods, for instance.

But what deserves to be successful isn’t always what ends up winning hearts and minds in the real world. In fact, empirical data we collected suggest that the viewership of such shows – even heavily publicized and celebrity-endorsed ones – is small and made up of people who are already highly educated, knowledgeable about science and receptive to scientific evidence.

Engaging scientific programming could still be an antidote to waning public interest in science, especially where formal science education is falling short. But it is revealing that “Cosmos” – a heavily marketed, big-budget show backed by Fox Networks and “Family Guy” creator Seth McFarlane – did not reach the audience who need quality science information the most. “Bill Nye Saves the World” might not either. Its streaming numbers are not yet available.

Today’s fragmented and partisan media environment fosters selective exposure and motivated reasoning – that is, viewers typically tune in to programming that confirms their existing worldview. There are few opportunities or incentives for audiences to engage with scientific evidence in the media. All of this can propagate misleading claims and deter audiences from accepting the conclusions of sound science. And adoption of misinformation and alternative facts is not a partisan problem. Policy debates questioning or ignoring scientific consensus on vaccines, climate change and GMOs have cut across different political camps.

None of this is meant to downplay the huge potential of entertainment media to reach diverse audiences beyond the proverbial choir. We know from decades of research that our mental images of science and its impact on society are shaped heavily by (sometimes stereotypical) portrayals of science and scientists in shows like “The Big Bang Theory” or “Orphan Black.”

But successful scientific entertainment programming needs to accomplish two goals: First, draw in a diverse audience well beyond those already interested in science; second, present scientific issues in a way that unites audiences around shared values rather than further polarizing by presenting science in ways that seems at odds with specific political or religious worldviews.

And social science research suggests that complex information can reach audiences via the most unlikely of places, including the satirical fake news program “The Colbert Report.” In fact, a University of Pennsylvania study showed that a series of “Colbert Report” episodes about Super PACs and 501(c)(4) groups during the 2012 presidential election did a better job educating viewers than did mainstream programming in traditional news formats.

Social science can help us learn from our mistakes and better understand how to connect with hard-to-reach audiences via new formats and outlets. None of these shows by themselves will save the world. But if done right, they each might get us closer, one empirical step at a time.

I encourage you to read the essay in its entirety and, in particular, to read the comments.

The tickets for the Aug. 11, 2017 event seem a bit expensive but as they appear to be sold out, it proves I know very little about marketing science celebrities. I guess Stroumboulopoulos’ name recognition due to his CBC (Canadian Broadcasting Corporation) experience was part of the sales strategy since he doesn’t seem to have any science background. That said, good interviewers take the time to research and often unearth questions that someone with more expertise might not think to ask. I’ve been favourably impressed the few times I’ve caught one of Stroumboulopoulos’ interviews.

Blackout: Night Sky Festival

The day after Bill Nye, on Saturday, August 12, 2017, there’s a special event at the Museum of Anthropology on the University of British Columbia grounds in Vancouver. Cecilia Lu in a July 24, 2017 posting on The Daily Hive (Vancouver edition) writes up the event,

With the Perseid meteor shower returning next month, the Museum of Anthropology is putting on a unique stargazing festival for the occasion.

On Saturday, August 12 [2017], at the peak of meteor shower viewing season, Blackout: Night Sky Festival will see the MOA transform into an all-ages arts and astronomy celebration.

There are two eclipses during August 2017 (Aug. 7, 2017 and Aug. 21, 2017) and I find it odd that neither are mentioned in this astronomy-focused event at the Museum of Anthropology.  The Aug. 21, 2017 astronomical event is a total eclipse of the sun.. There’s more about it on this NASA (US National Aeronautics Space Administration) eclipse website.

Sounding out the TRAPPIST-1 planetary system

It’s been a while since a data sonification story has come this way. Like my first posting on the topic (Feb. 7, 2014) this is another astrophysics ‘piece of music’. From the University of Toronto (Canada) and Thought Café (a Canadian animation studio),

For those who’d like a little text, here’s more from a May 10, 2017 University of Toronto news release (also on EurekAlert) by Don Campbell,

When NASA announced its discovery of the TRAPPIST-1 system back in February [2017] it caused quite a stir, and with good reason. Three of its seven Earth-sized planets lay in the star’s habitable zone, meaning they may harbour suitable conditions for life.

But one of the major puzzles from the original research describing the system was that it seemed to be unstable.

“If you simulate the system, the planets start crashing into one another in less than a million years,” says Dan Tamayo, a postdoc at U of T Scarborough’s Centre for Planetary Science.

“This may seem like a long time, but it’s really just an astronomical blink of an eye. It would be very lucky for us to discover TRAPPIST-1 right before it fell apart, so there must be a reason why it remains stable.”

Tamayo and his colleagues seem to have found a reason why. In research published in the journal Astrophysical Journal Letters, they describe the planets in the TRAPPIST-1 system as being in something called a “resonant chain” that can strongly stabilize the system.

In resonant configurations, planets’ orbital periods form ratios of whole numbers. It’s a very technical principle, but a good example is how Neptune orbits the Sun three times in the amount of time it takes Pluto to orbit twice. This is a good thing for Pluto because otherwise it wouldn’t exist. Since the two planets’ orbits intersect, if things were random they would collide, but because of resonance, the locations of the planets relative to one another keeps repeating.

“There’s a rhythmic repeating pattern that ensures the system remains stable over a long period of time,” says Matt Russo, a post-doc at the Canadian Institute for Theoretical Astrophysics (CITA) who has been working on creative ways to visualize the system.

TRAPPIST-1 takes this principle to a whole other level with all seven planets being in a chain of resonances. To illustrate this remarkable configuration, Tamayo, Russo and colleague Andrew Santaguida created an animation in which the planets play a piano note every time they pass in front of their host star, and a drum beat every time a planet overtakes its nearest neighbour.

Because the planets’ periods are simple ratios of each other, their motion creates a steady repeating pattern that is similar to how we play music. Simple frequency ratios are also what makes two notes sound pleasing when played together.

Speeding up the planets’ orbital frequencies into the human hearing range produces an astrophysical symphony of sorts, but one that’s playing out more than 40 light years away.

“Most planetary systems are like bands of amateur musicians playing their parts at different speeds,” says Russo. “TRAPPIST-1 is different; it’s a super-group with all seven members synchronizing their parts in nearly perfect time.”

But even synchronized orbits don’t necessarily survive very long, notes Tamayo. For technical reasons, chaos theory also requires precise orbital alignments to ensure systems remain stable. This can explain why the simulations done in the original discovery paper quickly resulted in the planets colliding with one another.

“It’s not that the system is doomed, it’s that stable configurations are very exact,” he says. “We can’t measure all the orbital parameters well enough at the moment, so the simulated systems kept resulting in collisions because the setups weren’t precise.”

In order to overcome this Tamayo and his team looked at the system not as it is today, but how it may have originally formed. When the system was being born out of a disk of gas, the planets should have migrated relative to one another, allowing the system to naturally settle into a stable resonant configuration.

“This means that early on, each planet’s orbit was tuned to make it harmonious with its neighbours, in the same way that instruments are tuned by a band before it begins to play,” says Russo. “That’s why the animation produces such beautiful music.”

The team tested the simulations using the supercomputing cluster at the Canadian Institute for Theoretical Astrophysics (CITA) and found that the majority they generated remained stable for as long as they could possibly run it. This was about 100 times longer than it took for the simulations in the original research paper describing TRAPPIST-1 to go berserk.

“It seems somehow poetic that this special configuration that can generate such remarkable music can also be responsible for the system surviving to the present day,” says Tamayo.

I hear the proteins singing

Points to anyone who recognized the paraphrasing of the title for the well-loved, Canadian movie, “I heard the mermaids singing.” In this case, it’s all about protein folding and data sonification (from an Oct. 20, 2016 news item on phys.org),

Transforming data about the structure of proteins into melodies gives scientists a completely new way of analyzing the molecules that could reveal new insights into how they work – by listening to them. A new study published in the journal Heliyon shows how musical sounds can help scientists analyze data using their ears instead of their eyes.

The researchers, from the University of Tampere in Finland, Eastern Washington University in the US and the Francis Crick Institute in the UK, believe their technique could help scientists identify anomalies in proteins more easily.

An Oct. 20, 2016 Elsevier Publishing press release on EurekAlert, which originated the news item, expands on the theme,

“We are confident that people will eventually listen to data and draw important information from the experiences,” commented Dr. Jonathan Middleton, a composer and music scholar who is based at Eastern Washington University and in residence at the University of Tampere. “The ears might detect more than the eyes, and if the ears are doing some of the work, then the eyes will be free to look at other things.”

Proteins are molecules found in living things that have many different functions. Scientists usually study them visually and using data; with modern microscopy it is possible to directly see the structure of some proteins.

Using a technique called sonification, the researchers can now transform data about proteins into musical sounds, or melodies. They wanted to use this approach to ask three related questions: what can protein data sound like? Are there analytical benefits? And can we hear particular elements or anomalies in the data?

They found that a large proportion of people can recognize links between the melodies and more traditional visuals like models, graphs and tables; it seems hearing these visuals is easier than they expected. The melodies are also pleasant to listen to, encouraging scientists to listen to them more than once and therefore repeatedly analyze the proteins.

The sonifications are created using a combination of Dr. Middleton’s composing skills and algorithms, so that others can use a similar process with their own proteins. The multidisciplinary approach – combining bioinformatics and music informatics – provides a completely new perspective on a complex problem in biology.

“Protein fold assignment is a notoriously tricky area of research in molecular biology,” said Dr. Robert Bywater from the Francis Crick Institute. “One not only needs to identify the fold type but to look for clues as to its many functions. It is not a simple matter to unravel these overlapping messages. Music is seen as an aid towards achieving this unraveling.”

The researchers say their molecular melodies can be used almost immediately in teaching protein science, and after some practice, scientists will be able to use them to discriminate between different protein structures and spot irregularities like mutations.

Proteins are the first stop, but our knowledge of other molecules could also benefit from sonification; one day we may be able to listen to our genomes, and perhaps use this to understand the role of junk DNA [emphasis mine].

About 97% of our DNA (deoxyribonucleic acid) has been known for some decades as ‘junk DNA’. In roughly 2012, that was notion was challenged as Stephen S. Hall wrote in an Oct. 1, 2012 article (Hidden Treasures in Junk DNA; What was once known as junk DNA turns out to hold hidden treasures, says computational biologist Ewan Birney) for Scientific American.

Getting back to  2016, here’s a link to and a citation for ‘protein singing’,

Melody discrimination and protein fold classification by  Robert P. Bywater, Jonathan N. Middleton. Heliyon 20 Oct 2016, Volume 2, Issue 10 DOI: 10.1016/j.heliyon.2016.e0017

This paper is open access.

Here’s what the proteins sound like,

Joanna Klein has written an Oct. 21, 2016 article for the New York Times providing a slightly different take on this research (Note: Links have been removed),

“It’s used for the concert hall. It’s used for sports. It’s used for worship. Why can’t we use it for our data?” said Jonathan Middleton, the composer at Eastern Washington University and the University of Tampere in Finland who worked with Dr. Bywater.

Proteins have been around for billions of years, but humans still haven’t come up with a good way to visualize them. Right now scientists can shoot a laser at a crystallized protein (which can distort its shape), measure the patterns it spits out and simulate what that protein looks like. These depictions are difficult to sift through and hard to remember.

“There’s no simple equation like e=mc2,” said Dr. Bywater. “You have to do a lot of spade work to predict a protein structure.”

Dr. Bywater had been interested in assigning sounds to proteins since the 1990s. After hearing a song Dr. Middleton had composed called “Redwood Symphony,” which opens with sounds derived from the tree’s DNA, he asked for his help.

Using a process called sonification (which is the same thing used to assign different ringtones to texts, emails or calls on your cellphone) the team took three proteins and turned their folding shapes — a coil, a turn and a strand — into musical melodies. Each shape was represented by a bunch of numbers, and those numbers were converted into a musical code. A combination of musical sounds represented each shape, resulting in a song of simple patterns that changed with the folds of the protein. Later they played those songs to a group of 38 people together with visuals of the proteins, and asked them to identify similarities and differences between them. The two were surprised that people didn’t really need the visuals to detect changes in the proteins.

Plus, I have more about data sonification in a Feb. 7, 2014 posting regarding a duet based on data from Voyager 1 & 2 spacecraft.

Finally, I hope my next Steep project will include  sonification of data on gold nanoparticles. I will keep you posted on any developments.

Creative destruction for Canada’s fundamental science

After receiving an ‘invitation’ from the Canadian Science Policy Centre, I wrote an opinion piece, drawing on my submission for the public consultation on Canada’s fundamental science research. It seems the invitation was more of a ‘call’ for submissions and my piece did not end up being selected for inclusion on the website. So rather than waste the piece, here it is,

Creative destruction for Canada’s fundamental science

At a time when we are dealing with the consequences of our sins and virtues, fundamental science, at heart, an exercise in imagination, can seem a waste of precious time. Pollution and climate change (sins: ill-considered uses of technology) and food security and water requirements (virtues: efforts to improve health and save more lives) would seem to demand solutions not the flights of fancy associated with basic science. After all, what does the ‘big bang’ have to do with potable water?

It’s not an unfair question despite the impatience some might feel when answering it by citing a number of practical applications which are the result of all that ‘fanciful’ or ‘blue sky’ science. The beauty and importance of the question is that it will always be asked and can never be definitively answered, rendering it a near constant goad or insurance against complacency.

In many ways Canada’s review of fundamental science (deadline for comments was Sept. 30, 2016) is not just an examination of the current funding schemes but an opportunity to introduce more ‘goads’ or ‘anti-complacency’ measures into Canada’s fundamental science efforts for a kind of ‘creative destruction’.

Introduced by economist Joseph Schumpeter, the concept is derived from Karl Marx’s work but these days is associated with disruptive, painful, and regenerative innovation of all kinds and Canadian fundamental science needs more ‘creative destruction’. There’s at least one movement in this direction (found both in Canada and internationally) which takes us beyond uncomfortable, confrontative questions and occasional funding reviews—the integration of arts and humanities as an attempt at ‘creative destruction’ of the science endeavour.

At one point in the early 2000s, Canada developed a programme where the National Research Council could get joint funding with the Canada Council for the Arts for artists to work with their scientists. It was abandoned a few years later, as a failure. But, since then, several informal attempts at combining arts, sciences, and humanities have sprung up.

For example, Curiosity Collider (founded in 2015) hosts artists and scientists presenting their art/science pieces at various events in Vancouver. Beakerhead has mashed up science, engineering, arts, and entertainment in a festival founded and held in Calgary since 2013. Toronto’s ArtSci Salon hosts events and installations for local, national, and international collaborations of artists and scientists. And, getting back to Vancouver, Anecdotal Evidence is a science storytelling series which has been appearing sporadically since 2015.

There is a tendency to dismiss these types of collaboration as a form of science outreach designed to amuse or entertain but they can be much more than that. Illustrators have taught botanists a thing or two about plants. Markus Buehler at the Massachusetts Institute of Technology has used his understanding of music to explore material science (spider’s webs). Domenico Vicinanza has sonified data from space vehicle, Voyager 1, to produce a symphony, which is also a highly compressed means of communicating data.

C. P. Snow’s ‘The Two Cultures’ (lecture and book) covered much of the same territory in 1959 noting the idea that the arts and sciences (and humanities) can and should be linked in some fashion was not new. For centuries the sciences were referred to as Natural Philosophy (humanities), albeit only chemistry and physics were considered sciences, and many universities have or had faculties of arts and sciences or colleges of arts and science (e.g., the University of Saskatchewan still has such a college).

The current art/sci or sci-art movement can be seen as more than an attempt to resuscitate a ‘golden’ period from the past. It could be a means of embedding a continuous state of regeneration or ‘creative destruction’ for fundamental science in Canada.

Sonifying a swimmer’s performance to improve technique by listening)

I imagine since the 2016 Olympic Games are over that athletes and their coaches will soon start training for the 2020 Games. Researchers at Bielefeld University (Germany) have developed a new technique for helping swimmers improve their technique (Note: The following video is German language with English language subtitles),

An Aug. 4, 2016 Bielefeld University press release (also on EurekAlert), tells more,

Since 1896, swimming has been an event in the Olympic games. Back then it was the swimmer’s physical condition that was decisive in securing a win, but today it is mostly technique that determines who takes home the title of world champion. Researchers at Bielefeld University have developed a system that professional swimmers can use to optimize their swimming technique. The system expands the athlete’s perception and feel for the water by enabling them to hear, in real time, how the pressure of the water flows created by the swimmer changes with their movements. This gives the swimmer an advantage over his competitors because he can refine the execution of his technique. This “Swimming Sonification” system was developed at the Cluster of Excellence Cognitive Interaction Technology (CITEC) of Bielefeld University. In a video, Bielefeld University’s own “research_tv” reports on the new system.

“Swimmers see the movements of their hands. They also feel how the water glides over their hands, and they sense how quickly they are moving forwards. However, the majority of swimmers are not very aware of one significant factor: how the pressure exerted by the flow of the water on their bodies changes,” says Dr. Thomas Hermann of the Cluster of Excellence Cognitive Interaction Technology (CITEC). The sound researcher is working on converting data into sounds that can be used to benefit the listener. This is called sonification, a process in which measured data values are systematically turned into audible sounds and noises. “In this project, we are using the pressure from water flows as the data source,” says Hermann, who heads CITEC research group Ambient Intelligence. “We convert into sound how the pressure of water flows changes while swimming – in real time. We play the sounds to the swimmer over headphones so that they can then adjust their movements based on what they hear,” explains Hermann.

For this research project on swimming sonification, Dr. Hermann is working together with Dr. Bodo Ungerechts of the Faculty of Psychology and Sports Science. As a biomechanist, Dr. Ungerechts deals with how human beings control their movements, particularly with swimming. “If a swimmer registers how the flow pressure changes by hearing, he can better judge, for instance, how he can produce more thrust at similar energy costs. This give the swimmer a more encompassing perception for his movements in the water,” says Dr. Ungerechts. The researcher even tested the system out for himself. “I was surprised at just how well the sonification and the effects of the water flow, which I felt myself, corresponded with one another,” he says. The system is intuitive and easy to use. “You immediately starts playing with the sounds to hear, for example, what tonal effect spreading your fingers apart or changing the position of your hand has,” says Ungerechts. The new system should open up new training possibilities for athletes. “By using this system, swimmers develop a harmony – a kind of melody. If a swimmer very quickly masters a lap, they can use the recording of the melody to mentally re-imagine and retrace the successful execution of this lap. This mental training can also help athletes perform successfully in competitions.” To this, Thomas Hermann adds “the ear is great at perceiving rhythm and changes in rhythm. In this way, swimmers can find their own rhythm and use this to orient themselves in the water.”

This system includes two gloves with thin tube ends that serve as pressure sensors and are fixed between the fingers. The swimmer wears these gloves during practice. The tubes are linked to a measuring instrument, which is currently connected to the swimmer via a line while he or she is swimming. The measuring device transmits data about water flow pressure to a laptop. A custom-made software then sonifies the data, meaning that it turns the information into sound. “During repeated hand actions, for instance, the system can make rising and sinking flow pressure audible as increasing or decreasing tonal pitches,” says Thomas Hermann. Other settings that sonify features such as symmetry or steadiness can also be activated as needed.

The sounds are transmitted to the swimmer in real time over headphones. When the swimmer modifies a movement, he hears live how this also changes the sound. With the sonification of aquatic flow pressure, the swimmer can now practice the front crawl in way that, for instance, both hands displace the water masses with the same water flow form – to do this, the swimmer just has make sure that he generates the same sound pattern with each hand. Because the coach also hears the sounds over speakers, he can base the instructions he gives to the swimmer not only on the movements he observes, but also on the sounds generated by the swimmer and their rhythm (e.g. “Move your hands so that the tonal pitch increases faster”).

For this sonification project, Thomas Hermann and Bodo Ungerechts are working with Daniel Cesarini, Ph.D., a researcher from the Department of Information Engineering at the University of Pisa in Italy. Dr. Cesarini developed the measuring device that analyzes the aquatic flow pressure data.

In a practical workshop held in September 2015, professional swimmers tested the system out and confirmed that it indeed helped them to optimize their swimming technique. Of the 10 swimmers who participated, three of them qualify for international competitions, and one of the female swimmers is competing this year at the Paralympics in Rio de Janeiro, Brazil. The workshop was funded by the Cluster of Excellence Cognitive Interaction Technology (CITEC). In addition to this, swim teams at the PSV Eindhoven (Philips Sports Union Eindhoven) in the Netherlands tested the new system out for two months, using it as part of their technique training sessions. The PSV swim club competes in the top swimming league in the Netherlands.

“It is advantageous for swimmers to receive immediate feedback on their swimming form,” says Thomas Hermann. “People learn more quickly when they get direct feedback because they can immediately test how the feedback – in this case, the sound – changes when they try out something new.”

The researchers want to continue developing their current prototype. “We are planning to develop a wearable system that can be used independently by the user, without the help of others,” says Thomas Hermann. In addition to this, the new sonification method is planned to be incorporated into long-term training programs in cooperation with swim clubs.

My first post about sonification was this February 7, 2014 post titled, Data sonification: listening to your data instead of visualizing it.
