Arc’teryx performance apparel and University of British Columbia (Canada) scientists stay green and dry

Leave a reply

As rainy season approaches in the Pacific Northwest of Canada and the US, there’s some good news about a sustainable water- and oil-repellent fabric. Sadly, it won’t be available this year but it’s something to look forward to.

An August 10, 2020 news item on phys.org announces the news from the University of British Columbia (UBC) about a greener, water-repellent fabric,

A sustainable, non-toxic and high-performance water-repellent fabric has long been the holy grail of outdoor enthusiasts and clothing companies alike. New research from UBC Okanagan and outdoor apparel giant Arc’teryx is making that goal one step closer to reality with one of the world’s first non-toxic oil and water-repellent performance textile finishes.

…

An August 10, 2020 UBC Okanagan news release (also on EurekAlert), which originated the news item, provides more detail,

Outdoor fabrics are typically treated with perfluorinated compounds (PFCs) to repel oil and water. But according to Sadaf Shabanian, doctoral student at UBC Okanagan’s School of Engineering and study lead author, PFCs come with a number of problems.

“PFCs have long been the standard for stain repellents, from clothing to non-stick frying pans, but we know these chemicals have a detrimental impact on human health and the environment,” explains Shabanian. “They pose a persistent, long-term risk to health and the environment because they take hundreds of years to breakdown and linger both in the environment and our bodies.”

According to Mary Glasper, materials developer at Arc’teryx and collaborator on the project, these lasting impacts are one of the major motivations for clothing companies to seek out new methods to achieve the same or better repellent properties in their products.

To solve the problem, Shabanian and the research team added a nanoscopic layer of silicone to each fibre in a woven fabric, creating an oil-repellent jacket fabric that repels water, sweat and oils.

By understanding how the textile weave and fibre roughness affect the liquid interactions, Shabanian says she was able to design a fabric finish that did not use any PFCs.

“The best part of the new design is that the fabric finish can be made from biodegradable materials and can be recyclable,” she says. “It addresses many of the issues related to PFC-based repellent products and remains highly suitable for the kind of technical apparel consumers and manufacturers are looking for.”

Arc’teryx is excited about the potential of this solution.

“An oil- and water-repellent finish that doesn’t rely on PFCs is enormously important in the world of textiles and is something the whole outdoor apparel industry has been working on for years,” says Glasper. “Now that we have a proof-of-concept, we’ll look to expand its application to other DWR-treated textiles used in our products and to improve the durability of the treatment.”

“Working to lessen material impacts on the environment is crucial for Arc’teryx to meet our goal of reducing our greenhouse gas emissions by 65 per cent in intensity by 2030,” she adds.

Kevin Golovin, principal investigator of the Okanagan Polymer Engineering Research & Applications Lab where the research was done, says the new research is important because it opens up a new area of green textile manufacturing.

He explains that while the new technology has immense potential, there are still several more years of development and testing needed before people will see fabrics with this treatment in stores.

“Demonstrating oil repellency without the use of PFCs is a critical first step towards a truly sustainable fabric finish,” says Golovin. “And it’s something previously thought impossible.”

The research is funded through a grant from the Natural Sciences and Engineering Research Council of Canada (NSERC), with support from Arc’teryx Equipment Inc.

Arc’teryx is based in North Vancouver (Canada).

Glass sponge reefs: ‘living dinosaurs’ of the Pacific Northwest waters

One of them looks to be screaming (Edvard Munch, anyone?) and none of it looks how I imagined an oceanic ‘living dinosaur’ might. While the news is not in my main area of interest (emerging technology), it is close to home. A June 1, 2020 University of British Columbia news release (also on EurekAlert) describes the glass sponge reefs (living dinosaurs) in the Pacific Northwest and current concerns about their welfare,

Warming ocean temperatures and acidification drastically reduce the skeletal strength and filter-feeding capacity of glass sponges, according to new UBC research.

The findings, published in Scientific Reports, indicate that ongoing climate change could have serious, irreversible impacts on the sprawling glass sponge reefs of the Pacific Northwest and their associated marine life – the only known reefs of their kind in the world.

Ranging from the Alaska-Canada border and down through the Strait of Georgia, the reefs play an essential role in water quality by filtering microbes and cycling nutrients through food chains. They also provide critical habitat for many fish and invertebrates, including rockfish, spot prawns, herring, halibut and sharks.

“Glass sponge reefs are ‘living dinosaurs’ thought to have been extinct for 40 million years before they were re-discovered in B.C. in 1986,” said Angela Stevenson, who led the study as a postdoctoral fellow at UBC Zoology. “Their sheer size and tremendous filtration capacity put them at the heart of a lush and productive underwater system, so we wanted to examine how climate change might impact their survival.”

Although the reefs are subject to strong, ongoing conservation efforts focused on limiting damage to their delicate glass structures, scientists know little about how these sponges respond to environmental changes.

For the study, Stevenson harvested Aphrocallistes vastus, one of three types of reef-building glass sponges, from Howe Sound and brought them to UBC where she ran the first successful long-term lab experiment involving live sponges by simulating their natural environment as closely as possible.

She then tested their resilience by placing them in warmer and more acidic waters that mimicked future projected ocean conditions.

Over a period of four months, Stevenson measured changes to their pumping capacity, body condition and skeletal strength, which are critical indicators of their ability to feed and build reefs.

Within one month, ocean acidification and warming, alone and in combination, reduced the sponges’ pumping capacity by more than 50 per cent and caused tissue losses of 10 to 25 per cent, which could starve the sponges.

“Most worryingly, pumping began to slow within two weeks of exposure to elevated temperatures,” said Stevenson.

The combination of acidification and warming also made their bodies weaker and more elastic by half. That could curtail reef formation and cause brittle reefs to collapse under the weight of growing sponges or animals walking and swimming among them.

Year-long temperature data collected from Howe Sound reefs in 2016 suggest it’s only a matter of time before sponges are exposed to conditions which exceed these thresholds.

“In Howe Sound, we want to figure out a way to track changes in sponge growth, size and area and area in the field so we can better understand potential climate implications at a larger scale,” said co-author Jeff Marliave, senior research scientist at the Ocean Wise Research Institute. “We also want to understand the microbial food webs that support sponges and how they might be influenced by climate cycles.”

Stevenson credits bottom-up community-led efforts and strong collaborations with government for the healthy, viable state of the B.C. reefs today. Added support for such community efforts and educational programs will be key to relieving future pressures.

“When most people think about reefs, they think of tropical shallow-water reefs like the beautiful Great Barrier Reef in Australia,” added Stevenson. “But we have these incredible deep-water reefs in our own backyard in Canada. If we don’t do our best to stand up for them, it will be like discovering a herd of dinosaurs and then immediately dropping dynamite on them.”

Background:

The colossal reefs can grow to 19 metres in height and are built by larval sponges settling atop the fused dead skeletons of previous generations. In northern B.C. the reefs are found at depths of 90 to 300 metres, while in southern B.C., they can be found as shallow as 22 metres.

The sponges feed by pumping sea water through their delicate bodies, filtering almost 80 per cent of microbes and particles and expelling clean water.

It’s estimated that the 19 known reefs in the Salish Sea can filter 100 billion litres of water every day, equivalent to one per cent of the total water volume in the Strait of Georgia and Howe Sound combined.

Here’s more about the painting, from The Scream webpage on edvardmunch.org,

Munch’s The Scream is an icon of modern art, the Mona Lisa for our time. As Leonardo da Vinci evoked a Renaissance ideal of serenity and self-control, Munch defined how we see our own age – wracked with anxiety and uncertainty.

Essentially The Scream is autobiographical, an expressionistic construction based on Munch’s actual experience of a scream piercing through nature while on a walk, after his two companions, seen in the background, had left him. …

For all the times I’ve seen the image, I had no idea the inspiration was acoustic.

In any event, the image seems sadly à propos both for the glass sponge reefs (and nature generally) and with regard to Black Lives Matter (BLM). A worldwide conflagration was ignited by George Floyd’s death in Minneapolis on May 25, 2020. This African-American man died while saying, “I can’t breathe,” as a police officer held Floyd down with a knee on his neck. RIP (rest in peace) George Floyd while the rest of us make the changes necessary, no matter how difficult to create a just and respectful world for all. Black Lives Matter.

Some amusements in the time of COVID-19

Gold stars for everyone who recognized the loose paraphrasing of the title, Love in the Time of Cholera, for Gabrial Garcia Marquez’s 1985 novel.

I wrote my headline and first paragraph yesterday and found this in my email box this morning, from a March 25, 2020 University of British Columbia news release, which compares times, diseases, and scares of the past with today’s COVID-19 (Perhaps politicians and others could read this piece and stop using the word ‘unprecedented’ when discussing COVID-19?),

How globalization stoked fear of disease during the Romantic era

In the late 18th and early 19th centuries, the word “communication” had several meanings. People used it to talk about both media and the spread of disease, as we do today, but also to describe transport—via carriages, canals and shipping.

Miranda Burgess, an associate professor in UBC’s English department, is working on a book called Romantic Transport that covers these forms of communication in the Romantic era and invites some interesting comparisons to what the world is going through today.

We spoke with her about the project.

What is your book about?

It’s about global infrastructure at the dawn of globalization—in particular the extension of ocean navigation through man-made inland waterways like canals and ship’s canals. These canals of the late 18th and early 19th century were like today’s airline routes, in that they brought together places that were formerly understood as far apart, and shrunk time because they made it faster to get from one place to another.

This book is about that history, about the fears that ordinary people felt in response to these modernizations, and about the way early 19th-century poets and novelists expressed and responded to those fears.

What connections did those writers make between transportation and disease?

In the 1810s, they don’t have germ theory yet, so there’s all kinds of speculation about how disease happens. Works of tropical medicine, which is rising as a discipline, liken the human body to the surface of the earth. They talk about nerves as canals that convey information from the surface to the depths, and the idea that somehow disease spreads along those pathways.

When the canals were being built, some writers opposed them on the grounds that they could bring “strangers” through the heart of the city, and that standing water would become a breeding ground for disease. Now we worry about people bringing disease on airplanes. It’s very similar to that.

What was the COVID-19 of that time?

Probably epidemic cholera [emphasis mine], from about the 1820s onward. The Quarterly Review, a journal that novelist Walter Scott was involved in editing, ran long articles that sought to trace the map of cholera along rivers from South Asia, to Southeast Asia, across Europe and finally to Britain. And in the way that its spread is described, many of the same fears that people are evincing now about COVID-19 were visible then, like the fear of clothes. Is it in your clothes? Do we have to burn our clothes? People were concerned.

What other comparisons can be drawn between those times and what is going on now?

Now we worry about the internet and “fake news.” In the 19th century, they worried about what William Wordsworth called “the rapid communication of intelligence,” which was the daily newspaper. Not everybody had access to newspapers, but each newspaper was read by multiple families and newspapers were available in taverns and coffee shops. So if you were male and literate, you had access to a newspaper, and quite a lot of women did, too.

Paper was made out of rags—discarded underwear. Because of the French Revolution and Napoleonic Wars that followed, France blockaded Britain’s coast and there was a desperate shortage of rags to make paper, which had formerly come from Europe. And so Britain started to import rags from the Caribbean that had been worn by enslaved people.

Papers of the time are full of descriptions of the high cost of rags, how they’re getting their rags from prisons, from prisoners’ underwear, and fear about the kinds of sweat and germs that would have been harboured in those rags—and also discussions of scarcity, as people stole and hoarded those rags. It rings very well with what the internet is telling us now about a bunch of things around COVID-19.

Plus ça change, n’est-ce pas?

And now for something completely different

Kudos to all who recognized the Monty Python reference. Now, onto the frogfish,

Thank you to the Monterey Bay Aquarium (in California, US).

A March 22, 2020 University of Washington (state) news release features an interview with the author of a new book on frogfishes,

Any old fish can swim. But what fish can walk, scoot, clamber over rocks, change color or pattern and even fight? That would be the frogfish.

The latest book by Ted Pietsch, UW professor emeritus of aquatic and fishery sciences, explores the lives and habits of these unusual marine shorefishes. “Frogfishes: Biodiversity, Zoogeography, and Behavioral Ecology” was published in March [2020] by Johns Hopkins University Press.

Pietsch, who is also curator emeritus of fishes at the Burke Museum of Natural History and Culture, has published over 200 articles and a dozen books on the biology and behavior of marine fishes. He wrote this book with Rachel J. Arnold, a faculty member at Northwest Indian College in Bellingham and its Salish Sea Research Center.

These walking fishes have stepped into the spotlight lately, with interest growing in recent decades. And though these predatory fishes “will almost certainly devour anything else that moves in a home aquarium,” Pietsch writes, “a cadre of frogfish aficionados around the world has grown within the dive community and among aquarists.” In fact, Pietsch said, there are three frogfish public groups on Facebook, with more than 6,000 members.

…

First, what is a frogfish?

Ted Pietsch: A member of a family of bony fishes, containing 52 species, all of which are highly camouflaged and whose feeding strategy consists of mimicking the immobile, inert, and benign appearance of a sponge or an algae-encrusted rock, while wiggling a highly conspicuous lure to attract prey.

This is a fish that “walks” and “hops” across the sea bottom, and clambers about over rocks and coral like a four-legged terrestrial animal but, at the same time, can jet-propel itself through open water. Some lay their eggs encapsulated in a complex, floating, mucus mass, called an “egg raft,” while some employ elaborate forms of parental care, carrying their eggs around until they hatch.

They are among the most colorful of nature’s productions, existing in nearly every imaginable color and color pattern, with an ability to completely alter their color and pattern in a matter of days or seconds. All these attributes combined make them one of the most intriguing groups of aquatic vertebrates for the aquarist, diver, and underwater photographer as well as the professional zoologist.

…

I couldn’t resist the ‘frog’ reference and I’m glad since this is a good read with a number of fascinating photographs and illustrations.,

Building with bacteria

A March 24, 2020 news item on phys.org features the future of building construction as perceived by synthetic biologists,

Buildings are not unlike a human body. They have bones and skin; they breathe. Electrified, they consume energy, regulate temperature and generate waste. Buildings are organisms—albeit inanimate ones.

But what if buildings—walls, roofs, floors, windows—were actually alive—grown, maintained and healed by living materials? Imagine architects using genetic tools that encode the architecture of a building right into the DNA of organisms, which then grow buildings that self-repair, interact with their inhabitants and adapt to the environment.

…

A March 23, 2020 essay by Wil Srubar (Professor of Architectural Engineering and Materials Science, University of Colorado Boulder), which originated the news item, provides more insight,

Living architecture is moving from the realm of science fiction into the laboratory as interdisciplinary teams of researchers turn living cells into microscopic factories. At the University of Colorado Boulder, I lead the Living Materials Laboratory. Together with collaborators in biochemistry, microbiology, materials science and structural engineering, we use synthetic biology toolkits to engineer bacteria to create useful minerals and polymers and form them into living building blocks that could, one day, bring buildings to life.

In one study published in Scientific Reports, my colleagues and I genetically programmed E. coli to create limestone particles with different shapes, sizes, stiffnesses and toughness. In another study, we showed that E. coli can be genetically programmed to produce styrene – the chemical used to make polystyrene foam, commonly known as Styrofoam.

Green cells for green building

In our most recent work, published in Matter, we used photosynthetic cyanobacteria to help us grow a structural building material – and we kept it alive. Similar to algae, cyanobacteria are green microorganisms found throughout the environment but best known for growing on the walls in your fish tank. Instead of emitting CO2, cyanobacteria use CO2 and sunlight to grow and, in the right conditions, create a biocement, which we used to help us bind sand particles together to make a living brick.

By keeping the cyanobacteria alive, we were able to manufacture building materials exponentially. We took one living brick, split it in half and grew two full bricks from the halves. The two full bricks grew into four, and four grew into eight. Instead of creating one brick at a time, we harnessed the exponential growth of bacteria to grow many bricks at once – demonstrating a brand new method of manufacturing materials.

Researchers have only scratched the surface of the potential of engineered living materials. Other organisms could impart other living functions to material building blocks. For example, different bacteria could produce materials that heal themselves, sense and respond to external stimuli like pressure and temperature, or even light up. If nature can do it, living materials can be engineered to do it, too.

It also take less energy to produce living buildings than standard ones. Making and transporting today’s building materials uses a lot of energy and emits a lot of CO2. For example, limestone is burned to make cement for concrete. Metals and sand are mined and melted to make steel and glass. The manufacture, transport and assembly of building materials account for 11% of global CO2 emissions. Cement production alone accounts for 8%. In contrast, some living materials, like our cyanobacteria bricks, could actually sequester CO2.

…

The field of engineered living materials is in its infancy, and further research and development is needed to bridge the gap between laboratory research and commercial availability. Challenges include cost, testing, certification and scaling up production. Consumer acceptance is another issue. For example, the construction industry has a negative perception of living organisms. Think mold, mildew, spiders, ants and termites. We’re hoping to shift that perception. Researchers working on living materials also need to address concerns about safety and biocontamination.

The [US] National Science Foundation recently named engineered living materials one of the country’s key research priorities. Synthetic biology and engineered living materials will play a critical role in tackling the challenges humans will face in the 2020s and beyond: climate change, disaster resilience, aging and overburdened infrastructure, and space exploration.

If you have time and interest, this is fascinating. Strubar is a little exuberant and, at this point, I welcome it.

Fitness

The Lithuanians are here for us. Scientists from the Kaunas University of Technology have just published a paper on better exercises for lower back pain in our increasingly sedentary times, from a March 23, 2020 Kaunas University of Technology press release (also on EurekAlert) Note: There are a few minor grammatical issues,

With the significant part of the global population forced to work from home, the occurrence of lower back pain may increase. Lithuanian scientists have devised a spinal stabilisation exercise programme for managing lower back pain for people who perform a sedentary job. After testing the programme with 70 volunteers, the researchers have found that the exercises are not only efficient in diminishing the non-specific lower back pain, but their effect lasts 3 times longer than that of a usual muscle strengthening exercise programme.

According to the World Health Organisation, lower back pain is among the top 10 diseases and injuries that are decreasing the quality of life across the global population. It is estimated that non-specific low back pain is experienced by 60% to 70% of people in industrialised societies. Moreover, it is the leading cause of activity limitation and work absence throughout much of the world. For example, in the United Kingdom, low back pain causes more than 100 million workdays lost per year, in the United States – an estimated 149 million.

Chronic lower back pain, which starts from long-term irritation or nerve injury affects the emotions of the afflicted. Anxiety, bad mood and even depression, also the malfunctioning of the other bodily systems – nausea, tachycardia, elevated arterial blood pressure – are among the conditions, which may be caused by lower back pain.

During the coronavirus disease (COVID-19) outbreak, with a significant part of the global population working from home and not always having a properly designed office space, the occurrence of lower back pain may increase.

“Lower back pain is reaching epidemic proportions. Although it is usually clear what is causing the pain and its chronic nature, people tend to ignore these circumstances and are not willing to change their lifestyle. Lower back pain usually comes away itself, however, the chances of the recurring pain are very high”, says Dr Irina Klizienė, a researcher at Kaunas University of Technology (KTU) Faculty of Social Sciences, Humanities and Arts.

Dr Klizienė, together with colleagues from KTU and from Lithuanian Sports University has designed a set of stabilisation exercises aimed at strengthening the muscles which support the spine at the lower back, i.e. lumbar area. The exercise programme is based on Pilates methodology.

According to Dr Klizienė, the stability of lumbar segments is an essential element of body biomechanics. Previous research evidence shows that in order to avoid the lower back pain it is crucial to strengthen the deep muscles, which are stabilising the lumbar area of the spine. One of these muscles is multifidus muscle.

“Human central nervous system is using several strategies, such as preparing for keeping the posture, preliminary adjustment to the posture, correcting the mistakes of the posture, which need to be rectified by specific stabilising exercises. Our aim was to design a set of exercises for this purpose”, explains Dr Klizienė.

The programme, designed by Dr Klizienė and her colleagues is comprised of static and dynamic exercises, which train the muscle strength and endurance. The static positions are to be held from 6 to 20 seconds; each exercise to be repeated 8 to 16 times.

The previous set is a little puzzling but perhaps you’ll find these ones below easier to follow,

I think more pictures of intervening moves would have been useful. Now. getting back to the press release,

In order to check the efficiency of the programme, 70 female volunteers were randomly enrolled either to the lumbar stabilisation exercise programme or to a usual muscle strengthening exercise programme. Both groups were exercising twice a week for 45 minutes for 20 weeks. During the experiment, ultrasound scanning of the muscles was carried out.

As soon as 4 weeks in lumbar stabilisation programme, it was observed that the cross-section area of the multifidus muscle of the subjects of the stabilisation group has increased; after completing the programme, this increase was statistically significant (p < 0,05). This change was not observed in the strengthening group.

Moreover, although both sets of exercises were efficient in eliminating lower back pain and strengthening the muscles of the lower back area, the effect of stabilisation exercises lasted 3 times longer – 12 weeks after the completion of the stabilisation programme against 4 weeks after the completion of the muscle strengthening programme.

“There are only a handful of studies, which have directly compared the efficiency of stabilisation exercises against other exercises in eliminating lower back pain”, says Dr Klizienė, “however, there are studies proving that after a year, lower back pain returned only to 30% of people who have completed a stabilisation exercise programme, and to 84% of people who haven’t taken these exercises. After three years these proportions are 35% and 75%.”

According to her, research shows that the spine stabilisation exercises are more efficient than medical intervention or usual physical activities in curing the lower back pain and avoiding the recurrence of the symptoms in the future.

Flexible graphene-rubber sensor for wearables

Courtesy: University of Waterloo

This waffled, greyish thing may not look like much but scientists are hopeful that it can be useful as a health sensor in athletic shoes and elsewhere. A March 6, 2020 news item on Nanowerk describes the work in more detail (Note: Links have been removed),

Researchers have utilized 3D printing and nanotechnology to create a durable, flexible sensor for wearable devices to monitor everything from vital signs to athletic performance (ACS Nano, “3D-Printed Ultra-Robust Surface-Doped Porous Silicone Sensors for Wearable Biomonitoring”).

The new technology, developed by engineers at the University of Waterloo [Ontario, Canada], combines silicone rubber with ultra-thin layers of graphene in a material ideal for making wristbands or insoles in running shoes.

A March 6, 2020 University of Waterloo news release, which originated the news item, delves further,

When that rubber material bends or moves, electrical signals are created by the highly conductive, nanoscale graphene embedded within its engineered honeycomb structure.

“Silicone gives us the flexibility and durability required for biomonitoring applications, and the added, embedded graphene makes it an effective sensor,” said Ehsan Toyserkani, research director at the Multi-Scale Additive Manufacturing (MSAM) Lab at Waterloo. “It’s all together in a single part.”

Fabricating a silicone rubber structure with such complex internal features is only possible using state-of-the-art 3D printing – also known as additive manufacturing – equipment and processes.

The rubber-graphene material is extremely flexible and durable in addition to highly conductive.

“It can be used in the harshest environments, in extreme temperatures and humidity,” said Elham Davoodi, an engineering PhD student at Waterloo who led the project. “It could even withstand being washed with your laundry.”

The material and the 3D printing process enable custom-made devices to precisely fit the body shapes of users, while also improving comfort compared to existing wearable devices and reducing manufacturing costs due to simplicity.

Toyserkani, a professor of mechanical and mechatronics engineering, said the rubber-graphene sensor can be paired with electronic components to make wearable devices that record heart and breathing rates, register the forces exerted when athletes run, allow doctors to remotely monitor patients and numerous other potential applications.

Researchers from the University of California, Los Angeles and the University of British Columbia collaborated on the project.

An immigrant psychiatrist develops psychosis and then schizophrenia. He walks a long path towards reconnection with himself, his son, and humanity.

Walk with him.

Within our immersive design (a fabric of sound, video, and live actors) lean in close to the possibilities of perceptual experience.

Schizophrenics ‘hear voices’. Schizophrenics fear loss of control over their own thoughts and bodies. But how does any one of us actually separate internal and external voices? How do we trust what we see or feel? How do we know which voices are truly our own?

Within the installation find places of retreat from chaos. Find poetry. Find critical analysis.

Explore archival material, Fanon’s writings and contemporary interviews with psychiatrists, neuroscientists, artists, and people living with schizophrenia, to reflect on the relationships between identity, history, racism and mental health.

I was able to find out more in a November 6, 2019 article at broadwayworld.com (Note: Some of this is repetitive),

Sounds and Science: Vienna meets Vancouver on November 30, 2019

‘Sounds and Science’ originated at the Medical University of Vienna (Austria) as the November 6, 2019 event posting on the University of British Columbia’s (UBC) Faculty of Medicine website,

The University of British Columbia will host the first Canadian concert bringing leading musical talents of Vienna together with dramatic narratives from science and medicine.

“Sounds and Science: Vienna Meets Vancouver” is part of the President’s Concert Series, to be held Nov. 30, 2019 on UBC campus. The event is modeled on a successful concert series launched in Austria in 2014, in cooperation with the Medical University of Vienna.

“Basic research tends to always stay within its own box, yet research is telling the most beautiful stories,” says Dr. Josef Penninger, director of UBC’s Life Sciences Institute, a professor of medical genetics and a Canada 150 Chair. “With this concert, we are bringing science out of the ivory tower, using the music of great composers such as Mozart, Schubert or Strauss to transport stories of discovery and insight into the major diseases that affected the composers themselves, and continue to have a significant impact on our society.”

Famous composers of the past are often seen as icons of classical music, but in fact, they were human beings, living under enormous physical constraints – perhaps more than people today, according to Dr. Manfred Hecking, an associate professor of internal medicine at the Medical University of Vienna.

“But ‘Sounds and Science’ is not primarily about suffering and disease,” says Dr. Hecking, a former member of the Vienna Philharmonic Orchestra who will be playing double bass during the concert. “It is a fun way of bringing music and science together. Combining music and thought, we hope that we will reach the attendees of the ‘Sounds and Science’ concert in Vancouver on an emotional, perhaps even personal level.”

A showcase for Viennese music, played in the tradition of the Vienna Philharmonic by several of its members, as well as the world-class science being done here at UBC, “Sounds and Science” will feature talks by UBC clinical and research faculty, including Dr. Penninger. Their topics will range from healthy aging and cancer research to the historical impact of bacterial infections.

Combining music and thought, we hope that we will reach the attendees of the ‘Sounds and Science’ concert in Vancouver on an emotional, perhaps even personal level.

Faculty speaking at “Sounds and Science” will be:
Dr. Allison Eddy, professor and head, department of pediatrics, and chief, pediatric medicine, BC Children’s Hospital and BC Women’s Hospital;
Dr. Troy Grennan, clinical assistant professor, division of infectious diseases, UBC faculty of medicine;
Dr. Poul Sorensen, professor, department of pathology and laboratory medicine, UBC faculty of medicine; and
Dr. Roger Wong, executive associate dean, education and clinical professor of geriatric medicine, UBC faculty of medicine
UBC President and Vice-Chancellor Santa J. Ono and Vice President Health and Dr. Dermot Kelleher, dean, faculty of medicine and vice-president, health at UBC will also speak during the evening.

The musicians include two outstanding members of the Vienna Philharmonic – violinist Prof. Günter Seifert and violist-conductor Hans Peter Ochsenhofer, who will be joined by violinist-conductor Rémy Ballot and double bassist Dr. Manfred Hecking, who serves as a regular substitute in the orchestra.

For those in whose lives intertwine music and science, the experience of cross-connection will be familiar. For Dr. Penninger, the concert represents an opportunity to bring the famous sound of the Vienna Philharmonic to UBC and British Columbia, to a new audience. “That these musicians are coming here is a fantastic recognition and acknowledgement of the amazing work being done at UBC,” he says.

“Like poetry, music is a universal language that all of us immediately understand and can relate to. Science tells the most amazing stories. Both of them bring meaning and beauty to our world.”

“Sounds and Science” – Vienna Meets Vancouver is part of the President’s Concert Series | November 30, 2019 on campus at the Old Auditorium from 6:30 to 9:30 p.m.

The Sounds and Science website has a feature abut the upcoming Vancouver concert and it offers a history dating from 2008,

MUSIC AND MEDICINE

The idea of combining music and medicine into the “Sounds & Science” – scientific concert series started in 2008, when the Austrian violinist Rainer Honeck played Bach’s Chaconne in d-minor directly before a keynote lecture, held by Nobel laureate Peter Doherty, at the Austrian Society of Allergology and Immunology’s yearly meeting in Vienna. The experience at that lecture was remarkable, truly a special moment. “Sounds & Science” was then taken a step further by bringing several concepts together: Anton Neumayr’s medical histories of composers, John Brockman’s idea of a “Third Culture” (very broadly speaking: combining humanities and science), and finally, our perception that science deserves a “Red Carpet” to walk on, in front of an audience. Attendees of the “Sounds & Science” series have also described that music opens the mind, and enables a better understanding of concepts in life and thereby science in general. On a typical concert/lecture, we start with a chamber music piece, continue with the pathobiography of the composer, go back to the music, and then introduce our main speaker, whose talk should be genuinely understandable to a broad, not necessarily scientifically trained audience. In the second half, we usually try to present a musical climax. One prerequisite that “Sounds & Science” stands for, is the outstanding quality of the principal musicians, and of the main speakers. Our previous concerts/lectures have so far covered several aspects of medicine like “Music & Cancer” (Debussy, Brahms, Schumann), “Music and Heart” (Bruckner, Mahler, Wagner), and “Music and Diabetes” (Bach, Ysaÿe, Puccini). For many individuals who have combined music and medicine or music and science inside of their own lives and biographies, the experience of a cross-connection between sounds and science is quite familiar. But there is also this “fun” aspect of sharing and participating, and at the “Sounds & Science” events, we usually try to ensure that the event location can easily be turned into a meeting place.

At a guess, Science and Sounds started informally in 2008 and became a formal series in 2014.

There is a video but it’s in German. It’s enjoyable viewing with beautiful music but unless you have German language skills you won’t get the humour. Also it runs for over 9 minutes (a little longer than most of videos you’ll find here on FrogHeart),

Enjoy!
