Everyone’s talking about* insects/bugs: InsectNet technology, a park for bugs, and more

I have been stumbling across bug (or insect) research at a greater rate than usual and while the ‘bug-informed’ community is, no doubt, acutely aware of the loss of insect life, the severity of the situation was a revelation to me.

This work looks at adaptation strategies, from a March 5, 2025 Northwestern University (Chicago, Illinois) news release (also on EurekAlert) by Win Reynolds, Note: Links have been removed,

  • Insect populations, foundational to food chains and pollination, have dramatically declined over the past 20 years due to rapid climate change
  • Scientists identify two ways fly species from different climates (high-altitude forest and hot desert) have adapted to temperature
  • Paper provides evidence that changes in brain wiring and heat sensitivity contributed to shifting preference to hot or cold conditions, respectively
  • Results may help predict the impact of ongoing climate change on insect distribution and behavior

EVANSTON, Ill. — Tiny, cold-blooded animals like flies depend on their environment to regulate body temperature, making them ideal “canaries in the mine” for gauging the impact of climate change on the behavior and distribution of animal species. Yet, scientists know relatively little about how insect sense and respond to temperature.

Using two species of flies from different climates — one from the cool, high-altitude forests of Northern California, the other hailing from the hot, dry deserts of the Southwest (both cousins of the common laboratory fly, drosophila melanogaster) — Northwestern scientists discovered remarkable differences in the way each processes external temperature.

Forest flies showed increased avoidance of heat, potentially explained by higher sensitivity in their antennae’s molecular heat receptors, while desert flies were instead actively attracted to heat, a response that could be tracked to differences in brain wiring  in a region of the fly brain that helps compute the valence (inherent attractiveness or aversiveness) of sensory cues.

The scientists believe these two mechanisms may have accompanied the evolution of each species as it adapted to its distinctive thermal environment, starting from a common ancestor dating back 40 million years (not long after dinosaurs went extinct).

These findings, published today (March 5 [2025]) in the journal Nature, help understand how animals evolve the preferences for specific temperature environments and may help predict the impact of a rapidly changing climate on animal behavior and distribution.

‘Not enough people care about insects’

“Insects are especially threatened by climate change,” said Northwestern neurobiologist Marco Gallio. “Behavior is the first interface between an animal and its environment. Even before the struggle to survive or perish, animals can respond to climate change by migration and by changing their distribution. We are already seeing insect populations declining in many regions, and even insect vectors of disease like the Zika virus and malaria spreading into new areas.”

Gallio, a self-appointed “insect advocate,” is a professor in the neurobiology department and the Soretta and Henry Shapiro Research Professor in Molecular Biology at the Weinberg College of Arts and Sciences. His lab examines fruit flies and their sensing systems. Gallio acknowledged there is limited data because “not enough people care about the insects,” but that available figures record a dramatic decline in insects in the past 20 to 50 years. Though bug haters may rejoice, Gallio said the population decline in the animal group with the most species on Earth is nothing to celebrate.

In addition to their position at the foundation of most terrestrial food chains, insects pollinate 70% of our crops. Gallio said losing insect communities could cause catastrophic damage to ecosystems across the globe and have a direct impact on human wellbeing.

Understanding heat circuits in the brain

Previous work from the Gallio Lab focused on how small insects like laboratory flies respond to sensory cues like harmless and painful temperature changes.

“The common fruit fly is an especially powerful animal to study how the external world is represented and processed within the brain,” Gallio said. “Many years of work on fly genetics and neuroscience have given us a map of the fly brain more detailed than that of any other animal.”

In the present study, Gallio and colleagues wondered how the brain circuits and resulting behaviors compared in fly species that were very similar aside from their choices of thermal habitat.

Using genetic tools, including CRISPR [clustered regularly interspaced short palindromic repeats], to knock out certain genes and gene swaps between species, the team studied both the molecular and brain mechanisms that may explain species-specific differences in temperature preference.

Ph.D. student and lead author Matthew Capek explained that they first found differences in the molecules that detect heat, causing them to activate at different temperatures. And while Capek said the difference in activation could explain the forest flies’ preference for cooler environments, a shift in receptor activation was not enough to explain the behavior of the desert fly.

“The desert fly seemed actively attracted to warmer temperatures — around 90 degrees Fahrenheit compared to the forest fly’s sweet spot just below 70 degrees,” said Capek, who works in the Gallio lab. “In fact, the activation threshold of the antenna heat sensors corresponded to their favorite temperature range, which they will seek, rather than to a temperature they should avoid.”

“In other words, the fly doesn’t behave any longer as though the antennae are telling it to run away from dangerous heat; they seem to be telling it higher temperatures are good, and to approach them.”

High cost, high reward

Gallio was initially puzzled — deserts are hot, so it did not make sense that flies sought out heat — but a lab trip to the Anza Borrego desert of Southern California provided key inspiration.

“Deserts in this region are very hot during the day, but temperatures can drop extremely rapidly when the sun goes down, and night can be downright freezing,” said Alessia Para, also a key author of the study and a research associate professor of neurobiology. “Flies in this climate may need to constantly attend to the rapidly changing temperature and always seek the ideal range, finding shady spots during the day and hiding in cacti for warmth at night.”

Flies from more forgiving environments may instead ignore temperature except when it changes rapidly. Constantly detecting the right temperature is costly from an energy perspective, but for desert flies, it’s life or death.

“This comparative work is useful in a couple of different ways,” Gallio said. “When an animal is born, the brain is already programmed to know if many of the things it will encounter are bad or good for it, and we do not understand how that programming works.

These fly species represent a natural experiment because a stimulus that is good for one species is bad for the other, and we can study the differences that make it so. We also want to learn more about how animals have been able to adapt to different temperatures during evolution, so that we may be able to better understand and even predict how they react to ongoing climate change. Of course we care about the insects, and we hope that what we learn may help us appreciate and protect them better.”

Bugs Matter

Thanks to buglife.org.uk for the subhead and the report. Here’s more from their April 30, 2025 press release, Note: Links have been removed,

The troubling extent of insect declines across the UK has been highlighted once again by the results of the 2024 Bugs Matter citizen science survey published today. The latest data shows that the number of flying insects sampled on vehicle number plates, across the UK, has fallen by a staggering 63% since 2021.

The Bugs Matter survey, led by Kent Wildlife Trust in partnership with invertebrate charity Buglife, relies on a nationwide network of volunteer citizen scientists who record insect splats on their vehicle number plates after journeys, using the Bugs Matter app built by Natural Apptitude. Analysis of records from more than 25,000 journeys across the UK since 2021 shows an alarming decrease in bug splats but data from 2024 shows this decrease has slowed.

Insects are critical to ecosystem functioning and services. They pollinate crops, provide natural pest control, decompose waste and recycle nutrients, and underpin food chains that support birds, mammals and other wildlife. Without insects, the planet’s ecological systems would collapse.

Dr. Lawrence Ball of Kent Wildlife Trust stated: “This huge decrease in insect splats over such a short time is really alarming. Its most likely that we are seeing the compounding effects of both a background rate of decline as well as a short term cycle of decline, perhaps linked to the extreme climate in the UK in recent years. Bug splats declined 8% from 2023 to 2024, following sharper drops of 44% in 2023 and 28% in 2022. This shows the rate of decline has slowed and it may even flatten or reverse next year. Continued support from citizen scientists is key to revealing the overall trend in insect numbers.”

The new data shows a decrease in insect splat rates across all the UK nations, with the sharpest fall between 2021 and 2024 recorded in Scotland at 65%. In England, the number of insect splats fell by 62%, in Wales by 64%, and in Northern Ireland by 55%, over the same time period.

Andrew Whitehouse, from Buglife added: “The latest Bugs Matter data suggests that the abundance of flying insects in our countryside has fallen again. The consequences are potentially far-reaching, not only impacting the health of the natural world, but affecting so many of the essential services that nature provides for us. Human activities continue to have a huge impact on nature, habitat loss and damage, pesticide use, pollution, and climate change all contribute to the decline in insects. Society must heed the warning signs of ecological collapse, and take urgent action to restore nature.”

Participation in Bugs Matter is growing and the number of journeys recorded in 2024 far exceeded previous years. This is in part thanks to a new partnership with Openreach, owner of the nation’s second largest commercial van fleet.

Peter Stewart, Openreach’s UK Operations Director for Service Delivery said: “We’re excited to participate in the ‘Bugs Matter’ survey for the second year. Our engineers travel millions of miles annually across the UK to build and maintain our network, making it easy for them to measure insect splats on vehicle number plates. We recognise the crucial role pollinators play for all of us to thrive, and as part of our strategy to protect nature, we’re proud to support this campaign again. Last year, we contributed around 10% of the registered journeys, and with our 25,000-strong fleet, we aim to do even better this year.”

Andrew Whitehouse concluded: “Thank you to everyone who participated in the Bugs Matter survey in 2024. Your contribution has provided invaluable insights into the health of our insect populations and wider environment. We are relaunching the survey on May 1 this year [2025], and with our expansion into the Republic of Ireland, we hope to engage even more people in this crucial citizen science effort.”

The 2025 Bugs Matter survey will run from Saturday 1 May to Tuesday 30 September. It is quick, free and easy to get involved – simply download the free mobile phone app and start recording insect splats on vehicle journeys.

Expansion into Republic of Ireland

In response to growing interest and the need for more comprehensive data, the Bugs Matter survey is expanding into the Republic of Ireland for the 2025 season, thanks to the Amazon Web Services (AWS) Imagine Grant ‘Go Further, Faster’ Award received by Bugs Matter at the end of 2024. This grant provides vital resources to non-profit organisations looking to deploy cloud technology as a central tool to achieve their mission goals, and is providing Bugs Matter with a combination of funding, cloud computing credits, and engagement with AWS technical specialists. This marks an important step in building a more complete picture of insect populations across the British Isles, and future expansion of the Bugs Matter survey.

Dr. Lawrence Ball of Kent Wildlife Trust stated,We’re extremely grateful for the financial and technical support from Amazon Web Services, which means we can launch in Ireland this year and in more countries in 2026. If you drive or know someone who drives in Ireland, please download the app, sign up, and take part! The UK results highlight the importance of understanding insect numbers elsewhere.”

The charities caution that continued long-term monitoring is essential to track the precise magnitude of these alarming trends, but stress that the current pace of decline is clearly ecologically unviable. By taking part in the Bugs Matter survey each year, citizen scientists can provide crucial data to better understand insect population patterns and support evidence-based conservation actions.

Zac Sherratt’s April 30, 2025 article for the British Broadcasting Corporation’s (BBC) online news website offers little more information,

A survey tracking the “staggering” decline in insect numbers across the UK and Ireland has begun.

The Bugs Matter survey, led by Kent Wildlife Trust and invertebrate charity Buglife, runs from 1 May to 30 September each year and sees “citizen scientists” record the number of bug splats on their vehicle number plates after a journey.

Dr Ball [Dr. Lawrence Ball of Kent Wildlife Trust ] said: “Without insects, the planet’s ecological systems would collapse so this huge decrease in insect splats over such a short time is really alarming.”

Bug splats declined 8% in 2024, following sharper drops of 44% in 2023 and 28% in 2022.

Dr Ball said the slowing rate of decline shows the curve may flatten or even reverse next year.

More than 25,000 journeys have been analysed as part of the survey since 2021.

IFLScience (and Bugpocalypse)

There’s an interesting back story for IFLScience (which started life as as Facebook page titled, “I Fucking Love Science”). If you want to find out more about IFLScience’s origins and founder, there’s Elise Andrew’s Wikipedia entry.

Returning to the bugs, Dr. Russell Moul’s April 30 (?), 2025 article for IFLScience further highlights the plight of insects around the world, Note: Links have been removed,

Insect populations have been declining across the world at an alarming rate, but no one has been sure why. According to a new study, intense agricultural practices are at the top of the list of causes, but there are multiple interrelated factors that are all contributing to quickly killing off these vital creatures.

“Insects are fundamental to life on earth. They are really important pollinators, decomposers, and prey for birds, bats, reptiles, and other species”, Eliza Grames, Assistant Professor of Biological Sciences, told IFLScience.

“Insects pollinate around 80 percent of wild flowering plants, and 75 percent of agricultural crop species rely on insects for pollination. Without insects as decomposers, the earth would essentially be covered in manure. Cow manure takes 60 percent longer to deteriorate when insects are excluded from an area.”

But despite their importance, insect numbers are declining. In 2017, a devastating study demonstrated that there has been more than a 75 percent decline in insect populations over the last three decades. As a result, scientists have been seeking to identify the likely causes for this decline.

In order to understand which causes the scientific community has found so far, Grames and colleagues from Binghamton University examined some 175 scientific reviews, which contained over 500 hypothesized drivers behind the decline. This information allowed the team to create an interconnected network of 3,000 possible links, known as a meta-synthetic approach, which spanned everything from beekeeping and deforestation to urban sprawl and parasites.

Within this network of information, the team found that intensified agriculture was the most cited driver behind the mass die-off. This was linked to issues such as land-use change and insecticides. However, focusing solely on the most cited drivers is not the way to interpret this information. As the team note in their work, the results show how interconnected the drivers are, highlighting complex issues.

For example, the climate may be an important driver behind the decline, but there are aspects within that, such as extreme precipitation, fire, and temperature rises, which can then contribute to other drivers. It’s an extremely connected and synergistic network.

“The drivers of insect decline are really complex and there are many overlooked stressors that we should be thinking about and researching,” Grames told IFLScience.

If you have a little more time, you can find some interesting tidbits in Moul’s April 30 (?), 2025 article.

InsectNet

A February 6, 2025 news item on ScienceDaily announces an application that uses machine learning for insect identification,

A farmer notices an unfamiliar insect on a leaf.

Is this a pollinator? Or a pest? Good news at harvest time? Or bad? Need to be controlled? Or not?

That farmer can snap a picture, use a smartphone or computer to feed the photo into a web-based application called InsectNet and, with the help of machine learning technology, get back real-time information.

“The app identifies the insect and returns a prediction of its taxonomic classification and role in the ecosystem as a pest, predator, pollinator, parasitoid, decomposer, herbivore, indicator and invasive species,” said a scientific paper describing InsectNet recently published by the journal PNAS Nexus [PNAS stands for Proceedings of the National Academy of Sciences of the US]. Iowa State University’s Baskar Ganapathysubramanian and Arti Singh are the corresponding authors.

..

A February 5, 2025 Iowa State University news release (also on EurekAlert but published February 6, 2025), which originated the news item, delves further into InsectNet,

InsectNet – which is backed by a dataset of 12 million insect images, including many collected by citizen-scientists – provides identification and predictions for more than 2,500 insect species at more than 96% accuracy. When the application isn’t sure about an insect, it says it is uncertain, giving users more confidence when it does provide answers.

And, because the application was built as a global-to-local model, it can be geographically fine-tuned using expert-verified local and regional datasets. That makes it useful to farmers everywhere.

So, beware, armyworms, cutworms, grasshoppers, stink bugs and all the other harmful insects. And, hello, butterflies, bees and all the other pollinators. Good to see you, lady beetles, mantises and all the other pest predators.

“We envision InsectNet to complement existing approaches, and be part of a growing suite of AI technologies for addressing agricultural challenges,” the authors wrote.

A village of researchers

InsectNet’s ability to be fine-tuned for specific regions or countries make it particularly useful, said Singh, an associate professor of agronomy.

In Iowa, for example, Singh said there are about 50 insect species particularly important to the state’s agricultural production. To identify and provide predictions about those insects, Singh said the project used about 500,000 insect images.

That could happen for farmers all over the globe. And wherever there isn’t sufficient data – these sophisticated models often require millions of images – for local fine-tuning, the global dataset is still available for farmers.

InsectNet isn’t just for farmers, though. Singh said it could also help agents at ports or border crossings identify invasive species. Or it could help researchers working on ecological studies.

So, the app is usable and flexible. But is it accessible?

You can’t go to an app store and download a version just yet, said Ganapathysubramanian, the Joseph and Elizabeth Anderlik Professor in Engineering and director of the AI Institute for Resilient Agriculture based at Iowa State. But the app is running on a server at Iowa State. With a QR code (see sidebar) or this URL (insectapp.las.iastate.edu/), users can upload insect pictures and get an identification and prediction.

This works throughout the stages of an insect’s life: from egg to larva to pupa to adult. It works with look-alike species. And it works with diverse image qualities and orientations.

The bottom line for any user is basic information about an insect: “Is this a pest?” Singh said. “Or is it a friend?”

Developers demonstrated the app during last August’s Farm Progress Show in Boone, Iowa. And now the research paper is introducing it to a broader, scientific audience.

But aren’t there already apps that help identify insects?

Yes, said Ganapathysubramanian, but they’re not to the scale of InsectNet and aren’t capable of global-to-local applications. And they’re also not open-source applications with technology that can be shared.

“Making InsectNet open source can encourage broader scientific efforts,” he said. “The scientific community can build on these efforts, rather than starting from scratch.”

The project also answered a lot of technical questions that could be applied to other projects, he said.

How much data is enough? Where can we get that much data? What can we do with noisy data?

How much computer power is necessary? How do we deal with so much data?

“Lastly, it takes a village of expertise to get to this point, right?” said Ganapathysubramanian.

It took agronomists and computer engineers and statisticians and data scientists and artificial intelligence specialists about two years to put InsectNet together and make it work.

“What we learned working with insects can be expanded to include weeds and plant diseases or any other related identification and classification problem in agriculture,” Singh said. “We’re very close to a one-stop shop for identifying all of these.”

Bugs and kids

The University of Adelaide’s (Australia) March 25, 2025 press release (also on EurekAlert but published March 24, 2025) announces some research on insect-related, school-based citizen science,

Pro-environmental behaviour increases among school students who participate in insect-related citizen science projects, according to new research from the University of Adelaide.

Students who participated in citizen science project Insect Investigators, which engages students in the discovery of new insects, not only expressed an intention to change their personal behaviour but also to encourage others to protect nature.

“As a result of their involvement in this program, students expressed intentions to further engage in insect–science–nature activities,” says the University of Adelaide’s Dr Erinn Fagan-Jeffries, who contributed to the study.

“In addition, teachers reported increased intentions to include insect-related topics in their teaching, which was positively associated with students’ own intentions for pro-environmental behaviour change.

“This suggests students’ response to the project influenced their teacher’s decision to include citizen science in their lessons.”

School-based citizen science projects facilitate authentic scientific interactions between research and educational institutions while exposing students to scientific processes.

“Teachers’ motivations for providing citizen science experiences to students was to create hands-on learning opportunities and to connect students with real science and scientists,” says Professor Patrick O’Connor AM, Director of the University’s School of Economics and Public Policy.

“Teachers reported interactions with researchers as invaluable. These interactions could take the form of in-person visits by team members, or even instructional videos and curriculum-linked teacher lesson plans.”

Incorporating insects into school-based citizen science projects can challenge widespread human misconceptions about insects and their roles in ecosystems, and foster human–insect connections.

“Given global concerns of rapid insect declines and the overarching biodiversity crisis, insect-focused, school-based citizen science projects can ultimately contribute towards equipping students with knowledge of, and actions to promote, insect conservation,” says lead author Dr Andy Howe, from the University of the Sunshine Coast.

“In Australia, approximately 33 per cent of insects are formally described, the remainder exist as ‘dark taxa’, to the detriment of environmental and biodiversity management initiatives.

“Encouraging more young people to engage in science not only engenders positive feelings in them towards the environment, it will also help to build the next generation of scientists who will fill in the vast knowledge gap that exists in the world of insects.”

Before getting to the link and citation, here’s an update on the Australian higher education ecosystem, from the March 24, 2025 version of the press release on EurekAlert ,

Bugs and parks

The University of British Columbia (UBC) issued an April 22, 2025 news release (also received via email) by Sachi Wickramasinghe announcing research on ‘parks for bugs’,

As the days get longer and gardeners plan their spring planting, research from the University of British Columbia offers some good news this Earth Day: small, simple changes to urban green spaces can make a big difference for pollinators. The study, published in Ecology Letters, found that reducing lawn mowing and creating pollinator meadows – think of them as ‘parks for bugs’– significantly boosts pollinator diversity, creating healthier and more resilient ecosystems.

A buzzing success

The three-year study, conducted in collaboration with the City of Vancouver’s pollinator meadows program, surveyed pollinators in 18 urban parks across Vancouver, comparing parks where meadows were planted and mowing was restricted with parks that remained as standard turfgrass lawns.

And while the tall grass caused a small stir among some neighbours, the results were striking: parks with meadows saw an immediate increase in pollinator species, with 21 to 47 more wild bee and hoverfly species compared to parks without meadows. The increase persisted over the three-year study period, suggesting that the meadow parks also support pollinators in the long run.

More than 100 species of wild bees and hoverflies were identified, with 35 of them only found in parks with meadows – including the Vancouver and Nevada bumble bee, some miner bees such as the Milwaukee miner bee, the red-faced miner bee and several species of hoverflies.

“Many people think of urban landscapes as poor environments for biodiversity, but our research shows that small actions can have a lasting impact,” said lead author Jens Ulrich, a PhD candidate in the faculty of land and food systems. “You don’t need a lot of space or resources to make a difference.”

Urban landscapes as pollinator havens

Unlike farmland, where large fields with monocrops can limit pollinator movement, urban areas are full of green spaces—gardens, parks, and even roadside boulevards—that can serve as pollinator refuges. The patchwork of small habitats allows species to move freely and settle into restored areas quickly.

The research highlights the importance of maintaining and expanding such efforts. Ongoing management, such as adding more native plants and controlling invasive species, can further strengthen pollinator communities.

The findings also offer practical guidance for city planners and community groups looking to enhance urban green spaces, and have already informed the City of Vancouver’s long-term planning—helping to establish pollinator meadows as a permanent option for parks and shaping future efforts to balance ecological function with aesthetic and cultural values.

“With so much land dedicated to lawns, there’s a major opportunity to rethink how we use these spaces,” said co-author Dr. Risa Sargent, an associate professor in the faculty of land and food systems. “Even small patches of insect-friendly meadows can provide critical resources for pollinators.”

Whether you have a backyard, balcony, or community garden plot, you can support pollinators with these simple steps:

  • Reduce mowing: Pollinators thrive in areas where flowers are allowed to bloom. Consider letting a section of your lawn grow longer or mowing less frequently.
  • Plant native flowering shrubs and trees: Perennial species like native chokecherry, Pacific ninebark, oceanspray, native hawthorn, red flowering currant, salal, red-osier dogwood, snowberry and vine maple are great choices for British Columbia’s Lower Mainland.
  • Create a diverse habitat: Incorporate a variety of plants that bloom at different times of the year to provide food from spring to fall.
  • Avoid pesticides: Many urban areas, including Vancouver, have already restricted pesticide use, but avoiding chemical treatments in your own garden can further protect pollinators.
  • Leave natural nesting sites: Many native bees nest in the ground or in plant stems. Keeping some bare soil or leaving flower stalks through winter can provide valuable shelter.

David Watters who was supposed to be their ‘keynote’ speaker last year is listed as a 2023 co-keynote presenter and Omer Kaya who filled in as the ‘keynote’ for the 2022 symposium is back as a featured 2023 co-keynote presenter. There are two other returnees to the symposium, Karimah Es Sabar and Malcolm Campbell.

Data Meditation and three roundtables: a collection of Who Cares? March 2022 events

You can find out more about Toronto’s Art/Sci Salon’s Who Cares? speaker series in my February 9, 2022 posting. For this posting, I’m focusing on the upcoming March 2022 events, which are being offered online. From a March 7, 2022 Art/Sci Salon announcement (received via email),

We’re pleased to announce our next two events from our “Who Cares?” Speaker Series

Nous sommes heureux d’annoncer notre deuxième événement de notre “Who Cares?” Série de conferences

March 10 [2022], 2:00-3:00 pm [ET]

Data Meditation: Salvatore Iaconesi and Oriana Persico

HER – She Loves Data 

Nuovo Abitare

Join us for a discussion about questions like: 

Why does data have to be an extractive process?

What can we learn about ourselves through the data we generate everyday?

How can we use them as an expressive form to represent ourselves?

Data Meditations is the first ritual designed with the new approach of HER: She Loves Data, which addresses data as existential and cultural phenomena, and the need of creating experience (contemporary rituals) that allow societies and individuals to come together around data generating meaning, new forms of solidarity, empathy, interconnection and knowledge.

Rejoignez-nous pour une discussion basée sur des questions telles que : 

Pourquoi les données doivent-elles être un processus d’extraction ?

Que pouvons-nous apprendre par rapport à nous, grâce aux données que nous générons chaque jour ?

Comment pouvons-nous les utiliser comme une forme expressive pour nous représenter ?

Data Méditations est le premier rituel conçu avec la nouvelle approche de HER [elle] : She loves Data , qui parle des données en tant que phénomènes existentiels et culturels , mais également , la nécessité de créer des expériences [ rituels contemporains ] qui permettent aux sociétés et aux individus de se réunir autour de données générant du sens , de nouvelles formes de solidarité , empathie ,  d’interconnexion et de connaissance.

One lesson we have learnt in the past two years is that the pandemic has not single-handedly created a global health crisis, but has exacerbated and made visible one that was already in progress. The roots of this crisis are as cultural as they are economic and environmental.  Among the factors contributing to the crisis is a dominant orientation towards healthcare that privileges a narrow focus on data-centered technological fixes and praises the potentials of technological delegation. An unsustainable system has culminated in the passive acceptance and even the cold justification of triage as an inevitable evil in a time of crisis and scarcity.

What transdisciplinary practices can help ameliorate the atomizing pitfalls of turning the patient into data?
How can discriminatory practices such as triage, exclusion based on race, gender, and class, vaccine hoarding etc.. be addressed and reversed?
What strategies can we devise to foster genuine transdisciplinary approaches and move beyond the silo effects of specialization, address current uncritical trends towards technological delegation, and restore the centrality of human relations in healthcare delivery?

L’une des leçons que nous avons apprises au cours des deux dernières années est que la pandémie n’a pas créé à elle seule une crise sanitaire mondiale, mais qu’elle en a exacerbé et rendu visible une qui était déjà en cours. Les racines de cette crise sont aussi bien culturelles qu’économiques et environnementales. Parmi les facteurs qui contribuent à la crise figure une orientation dominante en matière de soins de santé, qui privilégie une vision étroite des solutions technologiques centrées sur les données et fait l’éloge du potentiel de la délégation technologique. Un système non durable a abouti à l’acceptation passive et même à la justification froide du triage comme un mal inévitable en temps de crise et de pénurie.

Quelles pratiques transdisciplinaires peuvent contribuer à améliorer les pièges de l’atomisation qui consiste à transformer le patient en données ?
Comment les pratiques discriminatoires telles que le triage, l’exclusion fondée sur la race, le sexe et la classe sociale, la thésaurisation des vaccins, etc. peuvent-elles être abordées et inversées ?
Quelles stratégies pouvons-nous concevoir pour favoriser de véritables approches transdisciplinaires et dépasser les effets de silo de la spécialisation, pour faire face aux tendances actuelles non critiques à la délégation technologique, et pour restaurer la centralité des relations humaines dans la prestation des soins de santé ?

Who Cares? a series of Art/Sci Salon talks and exhibitions in February and March 2022

COVID-19 has put health care workers in a more than usually interesting position and the Art/Sci Salon in Toronto, Canada is ‘creatively’ addressing the old, new, and emerging stresses. From the Who Cares? events webpage (also in a February 8, 2022 notice received via email),

“Who Cares?” is a Speaker Series dedicated to fostering transdisciplinary conversations between doctors, writers, artists, and researchers on contemporary biopolitics of care and the urgent need to move towards more respectful, creative, and inclusive social practices of care in the wake of the systemic cracks made obvious by the pandemic.

About the Series

Critiques of the health care sector are certainly not new and have been put forward by workers and researchers in the medical sector and in the humanities alike. However, critique alone fails to consider the systemic issues that prevent well-meaning practitioners to make a difference. The goal of this series is to activate practical conversations between people who are already engaged in transforming the infrastructures and cultures of care but have few opportunities to speak to each other. These interdisciplinary dialogues will enable the sharing of emerging epistemologies, new material approaches and pedagogies that could take us beyond the current crisis. By engaging with the arts as research, our guests use the generative insights of poetic and artistic practices to zoom in on the crucial issues undermining holistic, dynamic and socially responsible forms of care. Furthermore, they champion transdisciplinary dialogues and multipronged approaches directed at changing the material and discursive practices of care. 

Who cares? asks the following important questions:

How do we lay the groundwork for sustainable practices of care, that is, care beyond ‘just-in-time’ interventions?

What strategies can we devise to foster genuine transdisciplinary approaches that move beyond the silo effects of specialization, address current uncritical trends towards technological delegation, and restore the centrality responsive/responsible human relations in healthcare delivery?

What practices can help ameliorate the atomizing pitfalls of turning the patient into data?

What pathways can we design to re-direct attention to long lasting care focused on a deeper understanding of the manifold relationalities between doctors, patients, communities, and the socio-environmental context?

How can the critically creative explorations of artists and writers contribute to building resilient communities of care that cultivate reciprocity, respect for the unpredictable temporalities of healing, and active listening?

How to build a capacious infrastructure of care able to address and mend the damages caused by ideologies of ultimate cure that pervade corporate approaches to healthcare funding and delivery?

The first event starts on February 14, 2022 (from the On care, beauty, and Where Things Touch webpage),

On care, beauty, and Where Things Touch

Bahar Orang (University of Toronto, Psychiatry)

This event will be online, please register HERE to participate. After registering, you will receive a confirmation email containing information about joining the meeting. 

A Conversation with Bahar Orang, author of Where Things Touch, on staying attuned to the fragile intimacies of care beyond the stifling demands of institutional environments. 

This short presentation will ask questions about care that move it beyond the carceral logics of hospital settings, particularly in psychiatry. Drawing from questions raised in my first book Where Things Touch, and my work with Doctors for Defunding Police (DFDP), I hope to pose the question of how to do the work of health care differently. As the pandemic has laid bare so much violence, it becomes imperative to engage in forms of political imaginativeness that proactively ask what are the forms that care can take, and does already take, in places other than the clinic or the hospital? 

Bahar Orang is a writer and clinician scholar in the Department of Psychiatry at the University of Toronto. Her creative and clinical work seeks to engage with ways of imagining care beyond the carcerality that medical institutions routinely reproduce

Chocolate at Canada’s synchrotron (Canadian Light Source; CLS)

An August 31, 2021 Canadian Light Source (CLS) news release by Erin Matthews describes research which could change how chocolate is made,

Scientists used synchrotron technology to show a key ingredient can create the ideal chocolate structure and could revolutionize the chocolate industry.

Structure is key when it comes creating the best quality of chocolate. An ideal internal structure will be smooth and continuous, not crumbly, and result in glossy, delicious, melt-in-your-mouth decadence. However, this sweet bliss is not easy to achieve.

Researchers from the University of Guelph had their first look at the detailed structure of dark chocolate using the Canadian Light Source (CLS) at the University of Saskatchewan. Their results were published today in Nature Communications.

“One of the major problems in chocolate making is tempering,” said Alejandro Marangoni, a professor at the University of Guelph and Canada Research Chair in Food, Health and Aging. “Very much like when you temper steel, you have to achieve a certain crystalline structure in the cocoa butter.”

Skilled chocolate makers [emphasis mine] use specialized tools and training to manipulate cocoa butter for gourmet chocolate. However, Marangoni wondered if adding a special ingredient to chocolate could drive the formation of the correct crystal structure without the complex cooling and mixing procedures typically used by chocolatiers during tempering.

“Imagine if you could add a component that directs the entire crystallization process to a high-quality finished product. You wouldn’t need fancy tempering protocols or industrial machines — you could easily achieve the desired crystalline form just by the addition of this component,” Marangoni said.

His team went to the CLS to see if their secret ingredient, a specific phospholipid, could drive the formation of an ideal chocolate structure. The facility’s bright light, which is millions of times brighter than the sun, allowed the team to get images of the interior structure of their dark chocolate in exquisite detail.

“We have some of the most beautiful micrographs of the finished chocolate that were only possible because we did this work at the CLS,” said Marangoni.

In a world first, the researchers were able to get detailed imaging of the internal structure of dark chocolate, thanks to the synchrotron’s state of the art BMIT beamline.

“Working with the CLS, I would call it a next level interaction,” Marangoni added. “It was extremely easy to set up a project and we had enormous support from beamline scientists.”

In collaboration with CLS Plant Imaging Lead Jarvis Stobbs, Marangoni and colleagues were able to confirm the positive effect their ingredient had on obtaining the ideal structure for chocolate.

“We screened many minor lipid components that would naturally be present in chocolate and identified one preferred group. We then added a very specific molecule, a saturated phospholipid, to the chocolate mass and obtained the desired effect. This phospholipid formed a specific liquid crystal structure that would ‘seed’ the formation of cocoa butter crystals,” said Marangoni.

Their discovery that this phospholipid ingredient will drive the formation of ideal cocoa butter crystals could have a big impact on the way that chocolate is made.

“It could potentially revolutionize the chocolate industry, because we would not need very complex tempering machines,” Marangoni said. “This could open up the possibility for smaller manufacturers to produce chocolate without having the big capital investment for tempering machinery.”

Synchrotron research allows scientists to identify important details that are not possible to find with other techniques. Marangoni said that any small improvement on current manufacturing methods can have a very large impact on the food industry and can potentially save money for companies.

He added that while chocolate research pales in comparison to global problems, he emphasizes the impact food can have on our everyday lives.

“We have more serious problems like climate change and alternative energies and maybe even vegan foods, which we’re working on as well, but chocolate gives us that psychological pleasure. It’s one of these foods that makes us feel happy.”

This video shows the researcher’s delight,

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

Tempering of cocoa butter and chocolate using minor lipidic components by Jay Chen, Saeed M. Ghazani, Jarvis A. Stobbs & Alejandro G. Marangoni. Nature Communications volume 12, Article number: 5018 (2021) DOI: https://doi.org/10.1038/s41467-021-25206-1 Published 31 August 2021

This paper is open access.

According to a Sept. 2, 2021 article by Marc Fawcett-Atkinson for Canada’s National Observer, this work could lead to making chocolate production more sustainable

What happens to the skilled chocolate makers?

That’s one of my big questions. The other is what happens to us? In all these ‘improvements’ of which there are many being touted these days, what I notice is a lack of sensuality. In this particular case, no touch and no smell.

Increased food security with hexanal for younger looking, fresher tasting fruits and vegetables

Also known as an anti-aging agent for your fruit and vegetables, hexanal is an environmentally friendly chemical, which is found naturally. Research has led to a synthesized nanotechnology-enabled product now being commercialized. I’ve been following the story off and on since 2012 (see my ‘India, Sri Lanka, and Canada team up for nanotechnology-enabled food packaging‘ posting). I last wrote about the project in a December 29, 2015 posting.

For some reason, hexanal hit the news hard in 2019 having been preceded by some interest in 2018. What follows is an update and a timeline of sorts.

January 2019: More funding

A January 24,2019 essay (also published on the University of Guelph website on January 29, 2019) by Jayasankar Subramanian and Elizabeth Finnis, both are lead researchers on the the project and professors at the University of Guelph (Canada), provides an overview and an update of the hexanal project (Note: Links have been removed) ,

Fruits like mangoes, bananas, papayas and limes are shipped long distances before they get to your table. Many fruits are delicate, and there may be a long period of time that elapses between when the fruit is picked and its arrival in grocery stores and other markets. They’re often picked before they’re truly ripe in order to increase their shelf life.

Even so, globally, up to 40 per cent of all picked fruit can be lost and this represents billions of dollars. But what if we had the technology to delay fruit’s natural degradation process? This is where hexanal can make a difference.

Fruits like mangoes, bananas, papayas and limes are shipped long distances before they get to your table. Many fruits are delicate, and there may be a long period of time that elapses between when the fruit is picked and its arrival in grocery stores and other markets. They’re often picked before they’re truly ripe in order to increase their shelf life.

Even so, globally, up to 40 per cent of all picked fruit can be lost and this represents billions of dollars. But what if we had the technology to delay fruit’s natural degradation process? This is where hexanal can make a difference.

Hexanal is naturally produced by plants to ward off pests; our research at the University of Guelph has found that when it’s applied externally, hexanal can also slow down the aging process.

Like everything else, fruit ages with time. The shrivelling and rot is triggered by the enzyme phospholipase D (PLD), which causes the eventual collapse of the fruit’s membrane. Essentially, fruit membranes are snug, and function like a brick wall of phospholipid bilayers. Phospholipase D breaks the alignment of the bricks, causing the membrane to crumble. Hexanal acts by reducing and slowing the formation of PLD, which in turn slows the collapse of the fruit’s membrane.

In partnership with agricultural and social science researchers in Canada and five other countries, we have tested nine hexanal technologies. These include a spray formulation that gets applied to fruit when they’re still on trees, post-harvest dips, fruit wraps, stickers and sachets embedded with hexanal.

Our findings have implications for consumers, retailers and, more importantly, farmers. For example, when applied as a pre-harvest spray, hexanal can keep fruit on trees longer and keep it fresher after harvest — up to three weeks longer for mangoes.

Hexanal is naturally produced by all plants and is already found as an additive in some food products. Hexanal is also approved by Health Canada as a flavour formula. Our tests of synthesized hexanal sprays, dips and other technologies showed that there were no negative effects on plants, insects or other animals. In addition, hexanal evaporates within 24 hours, which means there’s no residue left on fruit.

Farmers who participated in hexanal testing in Canada and elsewhere were happy with the product both in terms of its effectiveness and bio-safety.

Currently, hexanal for agricultural use is in the two-year regulatory clearance process in Canada and the U.S. Once the process is complete, hexanal formulations are expected to be available for farmer use and can be accessed through companies with a license for production.

That’s a stunning difference, eh?

Funding

At about the same time as the Conversation essay by Subramanian and Finnis, the University of Guelph published (on the Council of Ontario Universities website) a January 27, 2019 news release announcing new funds for the project,

A University of Guelph research project that has already improved the livelihoods of small-scale Asian farmers will further expand worldwide, thanks to more than $4.2 million in federal support announced Friday afternoon.

The project involves innovative packaging developed in part by Guelph researchers using nanotechnology to improve the shelf life of mangoes, a major fruit crop in much of the world.

Already, the technology has helped to significantly reduce post-harvest losses in Sri Lanka and India. Poor storage meant that farmers routinely lost up to 40 per cent of their crops, worth upwards of $800 million a year. The new technology has also boosted per-acre revenue.

New funding support from the International Development Research Centre (IDRC) and Foreign Affairs, Trade and Development Canada will allow researchers to broaden this successful initiative to Kenya, Tanzania, and Trinidad and Tobago.

Researchers will also look at other fruit — bananas, grapes, papaya, nectarines and berries — and investigate ways to commercialize the technologies.

… it will also be a main pillar of the Guelph-East Africa Initiative, which U of G established to bring together stakeholders to support research and teaching in food, health, water, education, environment and community.

“This confirms our commitment to improve agriculture in East Africa and around the world.” [said John Livernois, interim vice-president {research} ]

The project involves the use of hexanal, a natural plant product that delays fruit ripening and aging. Guelph plant agriculture professor Gopi Paliyath holds an American patent on the discovery of hexanal as a post-harvest agent. It’s also an FDA-approved food additive.

The project also involves Guelph plant agriculture professors Paliyath and Al Sullivan; Loong-tak Lim from Food Science; and Elizabeth Finnis, Sociology and Anthropology. Foreign research partners are based at Tamil Nadu Agricultural University, India; Industrial Technical Institute, Sri Lanka; University of Nairobi, Kenya; Sokoine University of Agriculture, Tanzania; and the University of [the] West Indies, Trinidad and Tobago.

Prior to more funding: a memorandum of understanding

I’m having to guess as the document about the memorandum of understanding (MOU) to commercialize hexanal is not dated but it seems to have been produced in March 2018. (Canada’s International Development Research Centre ([IDRC] has a webpage about the memorandum but no memorandum that I could find.) I stumbled across this account of the event where the MOU was signed,

Ms. Jennifer Daubeny, Consulate General of Canada, delivered the special address narrating the significance of Canadian fundingin developing nanotechnologies to reduce post-harvest losses that enables food security in Asian Countries. Dr. K. Ramasamy, Vice Chancellor, Tamil Nadu Agricultural University [TNAU], Coimbatore presided over the function and highlighted the role of TNAU in knitting nanotechnology research framework and serving as a torch bearer in the country. He emphasized that the GAC-IDRC Project helped more than 60 students and researchers, developed two technologies, filed patents for two inventions, extensive infrastructure development besides helping more than 12,000 fruit growers in the State of Tamil Nadu. Dr. Jayasankar Subramanian, Professor, University of Guelph, Canada, explained the evolution of the project till reached the stage of technology delivery to benefit farmers. Dr. K.S. Subramanian, NABARD Chair Professor, TNAU, Coimbatore, lead Principal Investigator of the Project for India presented nanotechnologies developed to assist in the entire value chain from the farm to fork. Mr. Arun Nagarajan, President, Tamil Nadu Fruit Growers’ Association, explained that the fruit growers are eager to use the technology to improve their farm income. Mr. Terence Park, Managing Director, Smart Harvest Agri, Canada, [emphasis mine] bestowed interest to take forward the technologies to the farm gate and signed MOU with TNAU for the Commercialization of the Hexanal Formulation. Dr. G.J. Janavi,Professor & Head, Department of Nano Science & Technology, TNAU, Coimbatore welcomed the gathering and Dr. C. Sekar, Dean, Imayam Agricultural College,Turaiyur, and Co-PI of the Project proposed a formal vote of thanks.

The Canadian Consul General Ms. Jennifer Daubeny visited all the exhibits and interacted with students, scholars and researchers besides the NGO partner Myrada. She was very impressed with the technologies developed by TNAU in collaboration with University of Guelph, Canada, and looking forward to support research programs in the near future. More than 200 Scientists and Diplomats from Canada, students, scholars, university officials participated in the event.

Products launch by ITI, Colombo

Two of the project’s technology outputs -hexanal incorporated ITI Bio-wax and the Tree Fresh Formulation spray [emphasis mine] were transferred to Hayleys Agriculture Pvt. Ltd., a reputed Agro Service provider in Sri Lanka. The products were launched on 22ndMarch 2018 at the Taj Samudra Hotel, Colombo. The chief guest at the event was the Hon. Susil Premajayantha, Minister of Science Technology and Research (Min. ST&R). The guest of honour was H.E. David McKinnon, High Commissioner for Canada in Sri Lanka. Others present included the Secretary to the Min. ST&R, The Chairman and Director General, ITI, Mr Rizvi Zaheed, Hayleys Agriculture and his team, the Chairman, National Science Foundation, Sri Lanka, representative of the Chairman Sri Lanka Export Development Board, representatives from the Dialog mobile service provider, the Registrar of Pesticides, representing the Dir. Gen., of Agriculture, President of the Lanka Fruit and Vegetable Producers, Processors and Exporters Association, leading large scale mango, papaya and pineapple growers, several export and fruit processing company representatives, senior officials from the ITI, the multi-disciplinary ITI research team and our partner from CEPA. The press was also well represented and a total of 100 persons were present on this occasion. The Managing Director Hayles, the two PIs’ of the project, the High Commissioner for Canada, The Minister and for ST&R and the Secretary to the Ministry addressed the gathering and the new video clip on the project was viewed. The new products were jointly uncovered for display by the Hon. Minister and H.E., the High Commissioner. Samples of the products were distributed to the President of the Lanka Fruit and Vegetable Producers Processors and Exporters Association and to two leading mango growers. The Project team also took this opportunity to run a presentation on the various stages of the project and related activities, display posters on their research findings and to print and distribute the pamphlets on the same as well as on hexanal, the latter as prepared by our partners from the University of Guelph. The launch ended with a time of fellowship providing a useful opportunity for networking.

A YouTube video about the product launch of hexanal-based Bio-wax and the Tree Fresh Formulation spray (I don’t know if those were the permanent names or if they are specific to Sri Lanka and other countries will adopt other names) helped to establish the date for the MOU. You can find the video here.

Judging from the media stories, the team in India has provided most of the leadership for commercializing hexanal.

Commercialization 2019 and beyond

To sum up, after a memorandum of understanding is signed and some prototype products have been unveiled in India in 2018 then, in early 2019, there’s more funding announced by IDRC to expand the number of countries involved and to continue research into efforts to save other types of produce.

Moving things along is an August 15, 2019 news item on Agropages.com,

Two nano formulations would be commercialized by the Directorate of Agri business development of Tamil Nadu Agricultural University (TNAU) soon.  

Fruity fresh is a liquid nano formulation containing hexanal that keeps fruits and vegetables fresh for more days. The pre-harvest spray of Fruity Fresh extends the shelf life of mango for two weeks on trees and another two weeks under storage conditions by employing post-harvest dip methodology, Dr. A. Lakshmanan, Professor and Head, Department of Nano Science and Technology told a meet on “Linking Nano Stakeholders” held at the University.  

Hexanal has also been successfully encapsulated in polymer matrix either as an electro spun fibre matrix (Nano sticker) or nano-pellets that extends shelf life of fruits by 1-2 weeks during storage and transportation, he said.  

This sticker and pellets technology is highly user friendly and can be placed inside the cartons containing fruits during transport for enhancing the freshness.

According to a November 5, 2019 article by Pearly Neo for foodnavigator-asia.com, there is pricing for four products. Nano Sticker and Nano Pellet each will cost $US 0.028 and the spray, Fruity Fresh, will cost $US 4.23 to $US 5.65 for a one liter bottle diluted in 50 liters of water (for use on approximately five trees) and the Fruity Fresh dipping solution at $US 0.0071per kg.

As far as I’m aware none of these products are available in Canada but there is a website for Smart Harvest Agri, Canada although the name used is a little different. First, there’s the Federal Corporation Information listing for Smart Harvest Agritech Limited. You’ll notice there are two directors,

The company’s Smart Harvest website doesn’t list any products but it does discuss something they call “FRESHXtend technology” for fruits and vegetables.

Final comment

I sometimes hear complaints about government funding and what seems to be a lack of follow through with exciting research work being done in Canada. I hope that in the months to come that this story of an international collaboration, which started with three countries and has now expanded to at least six countries and has led to increased food security with an environmentally friendly material and commercialization of research, gets some attention.

From the few sources I’ve been able to find, it seems India and Sri Lanka are leading the commercialization charge while Canada has contributed to an Asian-led project which has now expanded to include Kenya, Tanzania, and Trinidad and Tobago. Bravo t them all!

Summer (2019) Institute on AI (artificial intelligence) Societal Impacts, Governance, and Ethics. Summer Institute In Alberta, Canada

The deadline for applications is April 7, 2019. As for whether or not you might like to attend, here’s more from a joint March 11, 2019 Alberta Machine Intelligence Institute (Amii)/
Canadian Institute for Advanced Research (CIFAR)/University of California at Los Angeles (UCLA) Law School news release
(also on globalnewswire.com),

What will Artificial Intelligence (AI) mean for society? That’s the question scholars from a variety of disciplines will explore during the inaugural Summer Institute on AI Societal Impacts, Governance, and Ethics. Summer Institute, co-hosted by the Alberta Machine Intelligence Institute (Amii) and CIFAR, with support from UCLA School of Law, takes place July 22-24, 2019 in Edmonton, Canada.

“Recent advances in AI have brought a surge of attention to the field – both excitement and concern,” says co-organizer and UCLA professor, Edward Parson. “From algorithmic bias to autonomous vehicles, personal privacy to automation replacing jobs. Summer Institute will bring together exceptional people to talk about how humanity can receive the benefits and not get the worst harms from these rapid changes.”

Summer Institute brings together experts, grad students and researchers from multiple backgrounds to explore the societal, governmental, and ethical implications of AI. A combination of lectures, panels, and participatory problem-solving, this comprehensive interdisciplinary event aims to build understanding and action around these high-stakes issues.

“Machine intelligence is opening transformative opportunities across the world,” says John Shillington, CEO of Amii, “and Amii is excited to bring together our own world-leading researchers with experts from areas such as law, philosophy and ethics for this important discussion. Interdisciplinary perspectives will be essential to the ongoing development of machine intelligence and for ensuring these opportunities have the broadest reach possible.”

Over the three-day program, 30 graduate-level students and early-career researchers will engage with leading experts and researchers including event co-organizers: Western University’s Daniel Lizotte, Amii’s Alona Fyshe and UCLA’s Edward Parson. Participants will also have a chance to shape the curriculum throughout this uniquely interactive event.

Summer Institute takes place prior to Deep Learning and Reinforcement Learning Summer School, and includes a combined event on July 24th [2019] for both Summer Institute and Summer School participants.

Confirmed speakers at Summer Institute include:

Alona Fyshe, University of Alberta/Amii (SI co-organizer)
Edward Parson, UCLA (SI co-organizer)
Daniel Lizotte, Western University (SI co-organizer)
Geoffrey Rockwell, University of Alberta
Graham Taylor, University of Guelph/Vector Institute
Rob Lempert, Rand Corporation
Gary Marchant, Arizona State University
Richard Re, UCLA
Evan Selinger, Rochester Institute of Technology
Elana Zeide, UCLA

Two questions, why are all the summer school faculty either Canada- or US-based? What about South American, Asian, Middle Eastern, etc. thinkers?

One last thought, I wonder if this ‘AI & ethics summer institute’ has anything to do with the Pan-Canadian Artificial Intelligence Strategy, which CIFAR administers and where both the University of Alberta and Vector Institute are members.

CRISPR/Cas9 as a tool for artists (Art/sci Salon January 2018 events in Toronto, Canada) and an event in Winnipeg, Canada

The Art/Sci Salon in Toronto, Canada is offering a workshop and a panel discussion (I think) on the topic of CRISPR( (clustered regularly interspaced short palindromic repeats)/Cas9.

CRISPR Cas9 Workshop with Marta De Menezes

From its Art/Sci Salon event page (on Eventbrite),

This is a two day intensive workshop on

Jan. 24 5:00-9:00 pm
and
Jan. 25 5:00-9:00 pm

This workshop will address issues pertaining to the uses, ethics, and representations of CRISPR-cas9 genome editing system; and the evolution of bioart as a cultural phenomenon . The workshop will focus on:

1. Scientific strategies and ethical issues related to the modification of organisms through the most advanced technology;

2. Techniques and biological materials to develop and express complex concepts into art objects.

This workshop will introduce knowledge, methods and living material from the life sciences to the participants. The class will apply that novel information to the creation of art. Finally, the key concepts, processes and knowledge from the arts will be discussed and related to scientific research. The studio-­‐lab portion of the course will focus on the mastering and understanding of the CRISPR – Cas9 technology and its revolutionary applications. The unparalleled potential of CRISPR ‐ Cas9 for genome editing will be directly assessed as the participants will use the method to make artworks and generate meaning through such a technique. The participants will be expected to complete one small project by the end of the course. In developing and completing these projects, participants will be asked to present their ideas/work to the instructors and fellow participants. As part of the course, participants are expected to document their work/methodology/process by keeping a record of processes, outcomes, and explorations.

This is a free event. Go here to register.

Do CRISPR monsters dream of synthetic futures?

This second event in Toronto seems to be a panel discussion; here’s more from its Art/Sci Salon event page (on Eventbrite),

The term CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) refers to a range of novel gene editing systems which can be programmed to edit DNA at precise locations. It allows the permanent modification of the genes in cells of living organisms. CRISPR enables novel basic research and promises a wide range of possible applications from biomedicine and agriculture to environmental challenges.

The surprising simplicity of CRISPR and its potentials have led to a wide range of reactions. While some welcome it as a gene editing revolution able to cure diseases that are currently fatal, others urge for a worldwide moratorium, especially when it comes to human germline modifications. The possibility that CRISPR may allow us to intervene in the evolution of organisms has generated particularly divisive thoughts: is gene editing going to cure us all? Or is it opening up a new era of designer babies and new types of privileges measured at the level of genes? Could the relative easiness of the technique allow individuals to modify bodies, identities, sexuality, to create new species and races? will it create new monsters? [emphasis mine] These are all topics that need to be discussed. With this panel/discussion, we wish to address technical, ethical, and creative issues arising from the futuristic scenarios promised by CRISPR.

For anyone who didn’t recognize (or, like me, barely remembers what it means) the title’s reference is to a famous science fiction story by Philip K. Dick. Here’s more from the Do Androids Dream of Electric Sheep? Wikipedia entry (Note: Links have been removed),

Do Androids Dream of Electric Sheep? (retitled Blade Runner: Do Androids Dream of Electric Sheep? in some later printings) is a science fiction novel by American writer Philip K. Dick, first published in 1968. The novel is set in a post-apocalyptic San Francisco, where Earth’s life has been greatly damaged by nuclear global war. Most animal species are endangered or extinct from extreme radiation poisoning, so that owning an animal is now a sign of status and empathy, an attitude encouraged towards animals. The book served as the primary basis for the 1982 film Blade Runner, and many elements and themes from it were used in its 2017 sequel Blade Runner 2049.

The main plot follows Rick Deckard, a bounty hunter who is tasked with “retiring” (i.e. killing) six escaped Nexus-6 model androids, while a secondary plot follows John Isidore, a man of sub-par IQ who aids the fugitive androids. In connection with Deckard’s mission, the novel explores the issue of what it is to be human. Unlike humans, the androids are said to possess no sense of empathy.

I wonder why they didn’t try to reference Orphan Black (its Wikipedia entry)? That television series was all about biotechnology. If not Orphan Black, what about a Frankenstein reference? It’s the 200th anniversary this year (2018) of the publication of the book which is the forerunner to all the cautionary tales that have come after.
