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?

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

Yes, it is possible for bacteria to become resistant to silver nanoparticles. However, that yes comes with some qualifications according to a July 13, 2021 news item on ScienceDaily (Note: Links have been removed),
Antimicrobials are used to kill or slow the growth of bacteria, viruses and other microorganisms. They can be in the form of antibiotics, used to treat bodily infections, or as an additive or coating on commercial products used to keep germs at bay. These life-saving tools are essential to preventing and treating infections in humans, animals and plants, but they also pose a global threat to public health when microorganisms develop resistance to them, a concept known as antimicrobial resistance.
One of the main drivers of antimicrobial resistance is the misuse and overuse of antimicrobial agents, which includes silver nanoparticles, [emphases mine] an advanced material with well-documented antimicrobial properties. It is increasingly used in commercial products that boast enhanced germ-killing performance — it has been woven into textiles, coated onto toothbrushes, and even mixed into cosmetics as a preservative.
The Gilbertson Group at the University of Pittsburgh [Pennsylvania, US} Swanson School of Engineering used laboratory strains of E.coli to better understand bacterial resistance to silver nanoparticles and attempt to get ahead of the potential misuse of this material. The team recently published their results in Nature Nanotechnology.

“Bacterial resistance to silver nanoparticles is understudied, so our group looked at the mechanisms behind this event,” said Lisa Stabryla, lead author on the paper and a recent civil and environmental PhD graduate at Pitt. “This is a promising innovation to add to our arsenal of antimicrobials, but we need to consciously study it and perhaps regulate its use to avoid decreased efficacy like we’ve seen with some common antibiotics.”
Stabryla exposed E.coli to 20 consecutive days of silver nanoparticles and monitored bacterial growth over time. Nanoparticles are roughly 50 times smaller than a bacterium.
“In the beginning, bacteria could only survive at low concentrations of silver nanoparticles, but as the experiment continued, we found that they could survive at higher doses,” Stabryla noted. “Interestingly, we found that bacteria developed resistance to the silver nanoparticles but not their released silver ions alone.”
The group sequenced the genome of the E.coli that had been exposed to silver nanoparticles and found a mutation in a gene that corresponds to an efflux pump that pushes heavy metal ions out of the cell.
“It is possible that some form of silver is getting into the cell, and when it arrives, the cell mutates to quickly pump it out,” she added. “More work is needed to determine if researchers can perhaps overcome this mechanism of resistance through particle design.”
The group then studied two different types of E.coli: a hyper-motile strain that swims through its environment more quickly than normally motile bacteria and a non-motile strain that does not have physical means for moving around. They found that only the hyper-motile strain developed resistance.
“This finding could suggest that silver nanoparticles may be a good option to target certain types of bacteria, particularly non-motile strains,” Stabryla said.
In the end, bacteria will still find a way to evolve and evade antimicrobials. The hope is that an understanding of the mechanisms that lead to this evolution and a mindful use of new antimicrobials will lessen the impact of antimicrobial resistance.
“We are the first to look at bacterial motility effects on the ability to develop resistance to silver nanoparticles,” said Leanne Gilbertson, assistant professor of civil and environmental engineering at Pitt. “The observed difference is really interesting and merits further investigation to understand it and how to link the genetic response – the efflux pump regulation – to the bacteria’s ability to move in the system.
“The results are promising for being able to tune particle properties for a desired response, such as high efficacy while avoiding resistance.”
This is from a January 13, 2022 SFU Café Scientifique notice (received via email),
Happy New Year! We are excited to announce our next virtual SFU Café Scientifique!
Thursday January 27, 2022, 5:00-6:30 pm
Dr. Jonathan Choy, SFU Molecular Biology and Biochemistry
The Immune System: Our Great Protector Against Dangerous Stuff
Our bodies are constantly in contact with material in the environment, such as microbes, that are harmful to our health. Despite this, most people are healthy because the immune system patrols our bodies and protects us from these harmful environmental components. In this Cafe Scientifique, Dr. Jonathan Choy from the Department of Molecular Biology and Biochemistry will discuss how the immune system does this.
I found Dr. Choy’s profile page on the SFU website and found this description for his research interests,
T Cell Biology
T cells are specialized cells of the immune system that protect host organisms from infection but that also contribute to a wide array of human diseases. Research in my laboratory is focused on understanding the mechanisms by which T cells become inappropriately activated in disease settings and how they cause organ damage. We have provided particular attention to how innate immune signals, such as cytokines secreted by innate immune cells and vascular cells, control the outcome of T cell responses. Within this context, processes that inhibit the activation of T cells are also being studied in order to potentially prevent disease-causing immune responses. Our studies on this topic are applied most directly to inflammatory vascular diseases, such as transplant arteriosclerosis and giant cell arteritis.
Nitric Oxide Signaling and Production
Nitric oxide (NO) is a bioactive gas that controls many cell biological responses. Dysregulation of its production and/or bioactivity is involved in many diseases. My laboratory is interested in understanding how NO effects cell signaling and how its production is controlled by NO synthases. We are specifically interested in how NO-mediated protein S-nitrosylation, a post-translational modification caused by NO, affects cell signaling pathways and cellular functions.
I gather from the Café Scientifique write up that Dr. Choy’s talk is intended for a more general audience as opposed to the description of his research interests which are intended for students of molecular biology and biochemistry/
For those who are unfamiliar with it, Simon Fraser University is located in the Vancouver area (Canada).
Before getting to the announcement, this talk and Q&A (question and answer) session is being co-hosted by ArtSci Salon at the Fields Institute for Research in Mathematical Sciences and the OCAD University/DMG Bodies in Play (BiP) initiative.
For anyone curious about OCAD, it was the Ontario College of Art and Design and then in a very odd government/marketing (?) move, they added the word university. As for DMG, in their own words and from their About page, “DMG is a not-for-profit videogame arts organization that creates space for marginalized creators to make, play and critique videogames within a cultural context.” They are located in Toronto, Ontario. Finally, the Art/Sci Salon and the Fields Institute are located at the University of Toronto.
As for the talk, here’s more from the November 28, 2021 Art/Sci Salon announcement (received via email),
Inspired by her own experience with the health care system to treat a post-reproductive disease, interdisciplinary artist [Camille] Baker created the project INTER/her, an immersive installation and VR [virtual reality] experience exploring the inner world of women’s bodies and the reproductive diseases they suffer. The project was created to open up the conversation about phenomena experienced by women in their late 30’s (sometimes earlier) their 40’s, and sometimes after menopause. Working in consultation with a gynecologist, the project features interviews with several women telling their stories. The themes in the work include issues of female identity, sexuality, body image, loss of body parts, pain, disease, and cancer. INTER/her has a focus on female reproductive diseases explored through a feminist lens; as personal exploration, as a conversation starter, to raise greater public awareness and encourage community building. The work also represents the lived experience of women’s pain and anger, conflicting thoughts through self-care and the growth of disease. Feelings of mortality are explored through a medical process in male-dominated medical institutions and a dearth of reliable information. https://inter-her.art/ [1]
In 2021, the installation was shortlisted for the Lumen Prize.
Join us for a talk and Q&A with the artist to discuss her work and its future development.
After registering, you will receive a confirmation email containing information about joining the meeting.
This talk is Co-Hosted by the ArtSci Salon at the Fields Institute for Research in Mathematical Sciences and the OCAD University/DMG Bodies in Play (BiP) initiative.
This event will be recorded and archived on the ArtSci Salon Youtube channel

A technology-packed tank top offers a simple, effective way to track astronauts’ vital signs and physiological changes during spaceflight, according to research being presented at the American Physiological Society annual meeting during the Experimental Biology (EB) 2021 meeting, held virtually April 27-30.
By monitoring key health markers over long periods of time with one non-intrusive device, researchers say the garment can help improve understanding of how spaceflight affects the body.
“Until now, the heart rate and activity levels of astronauts were monitored by separate devices,” said Carmelo Mastrandrea, PhD, a postdoctoral fellow at the Schlegel-University of Waterloo Research Institute for Aging in Canada, and the study’s first author. “The Bio-Monitor shirt allows simultaneous and continuous direct measurements of heart rate, breathing rate, oxygen saturation in the blood, physical activity and skin temperature, and provides a continuous estimate of arterial systolic blood pressure.”
The Bio-Monitor shirt was developed for the Canadian Space Agency by Carré Technologies based on its commercially available Hexoskin garment. In a study funded by the Canadian Space Agency, a team of researchers from the Schlegel-University of Waterloo Research Institute for Aging oversaw the first test of the shirt in space for a scientific purpose. Astronauts wore the shirt continually for 72 hours before their spaceflight and 72 hours during spaceflight, except for periods of water immersion or when the device conflicted with another activity.
The shirt’s sensors and accelerometer performed well, providing consistent results and a large amount of usable data. Based on these initial results, researchers say the shirt represents an improvement over conventional methods for monitoring astronauts’ health, which require more hands-on attention.
“By monitoring continuously and non-intrusively, we remove the psychological impacts of defined testing periods from astronaut measurements,” said Mastrandrea. “Additionally, we are able to gather information during normal activities over several days, including during daily activities and sleep, something that traditional testing cannot achieve.”
In flight, the astronauts recorded far less physical activity than the two and a half hours per day recorded in the monitoring period before takeoff, a finding that aligns with previous studies showing large reductions in physical activity during spaceflight. In addition to monitoring astronauts’ health and physical activity in space, Mastrandrea noted that the shirt could provide early warning of any health problems that occur as their bodies re-adapt to gravity back on Earth.
The commercial version of the Bio-Monitor shirt is available to the public, where it can be used for various applications including assessing athletic performance and monitoring the health of people with limited mobility. In addition to spaceflight, researchers are examining its potential use in other occupational settings that involve extreme environments, such as firefighting.
Mastrandrea will present this research in poster R2888 (abstract). Contact the media team for more information or to obtain a free press pass to access the virtual meeting.

Astronauts develop insulin resistance, and are at risk for cardiovascular deconditioning, during long-duration missions to the International Space Station (ISS) despite their daily exercise sessions (Hughson et al. Am J Physiol Heart Circ Physiol 310: H628–H638, 2016). Chronic unloading of the musculoskeletal and cardiovascular systems in microgravity dramatically reduces the challenge of daily activities, and the astronauts’ schedules limit them to approximately 30-min/day aerobic exercise. To understand the physical demands of spaceflight and how these change from daily life on Earth, the Vascular Aging experiment is equipping astronauts for 48-72h continuous recordings with the Canadian Space Agency’s Bio-Monitor wearable sensor shirt. The Bio-Monitor (Bio-M), developed from the commercial Hexoskin® device, consists of 3-lead ECG, thoracic and abdominal respiratory bands, 3-axis accelerometer, skin temperature and SpO2 sensor placed on the forehead. Our utilisation of this equipment necessitated the development of novel processing and visualisation techniques, to better interpret and guide subsequent data analyses [emphasis mine]. Here we present initial data from astronauts wearing the BioM prior to launch and aboard the ISS, demonstrating the ability to extract useful data from BioM, using software developed ‘in-house’.
Astronauts wore the Bio-M continually for 72-h except for periods of water immersion or when the device conflicted with another activity. After physical exercise, astronauts changed to a dry shirt. First, we assessed the key data-quality metrics to provide initial appraisals of acceptable recordings. Mean total recording length pre-flight (60.5 hours) was similar to that in-flight (66.5 hours), with a consistent distribution of recorded day (44% vs 45%, 6am-6pm) and night (56% vs 55%, 6pm-6am) hours (pre-flight vs in-flight respectively).
For each recording, quality assessment of ECG signals was performed for individual leads, before combining signals and cross-correlating R-waves to produce reliable heart-rate timings. Mean ECG quality for individual leads, represented here as the percentage of usable signal to total recording duration, was somewhat lower in-flight (92%) when compared to pre-flight (96%), likely caused by poor skin contact or dry shirt electrodes; combining lead signals as mentioned above improved the proportion of usable data to 97% and 98% respectively. Accelerometer recordings identified a significant reduction in high-force movements over the 72-hour recordings, with just over 2.5 hours/day of high-force activity in astronauts pre-flight vs 50 minutes/day in-flight. It should be noted however that accelerometer measurements in zero-gravity are likely to be reduced, and future refinement of activity data continues. Average heart rates in-flight showed little difference when compared to pre-flight, although future analyses will compare periods of sleep, rest, and activity to further refine this comparison.
We conclude that utilisation of the BioM hardware with our own analysis techniques produces high-quality data allowing for future interpretation and investigation of spaceflight-induced physiological adaptations.
As for Hexoskin (Carré Technologies inc.), I found out more on the About Us webpage of the Hexoskin website (Note: Links have been removed),
Hexoskin (Carré Technologies inc.)
Founded in 2006 in Montreal [Canada], Hexoskin is a growing private company, leader in non-invasive sensors, software, data science & AI services. The company headquartered in the bustling Rosemont neighborhood, provides solutions and services directly to customers & researchers; and through B2B contracts in pharmaceutical, academics, healthcare, security, defense, first responders, aerospace public & private organizations.
Hexoskin’s mission has always been to make the precise health data collected by its body-worn sensors accessible and useful for everyone. When the cofounders Pierre-Alexandre Fournier and Jean-François Roy started the company back in 2006, the existing technologies to report rich health data continuously didn’t exist. Hexoskin took a different approach to non-portable and invasive monitoring solutions by releasing in 2013 the first washable Smart Shirts that captures cardiac, respiratory, and activity body metrics. Today Hexoskin’s main R&D focus is the development of innovative body-worn sensors for health, mobile, and distributed software for health data management and analysis.
Since then, Hexoskin has designed the Hexoskin Connected Health Platform, a system to minimize user setup time and to maximize vital signs monitoring over long periods in a non-obstructive way with sensors embedded in a Smart Shirt. Data are synced to local and remote servers for health data management and analysis. The Hexoskin Smart Garments are clinically validated and are developed involving patients & clients to be comfortable and easy to use.
The system is the next evolution to improve the standard of care in the following therapeutic areas: respiratory, cardiology, mental health, behavioral and physiological psychology, somnology, aging and physical performance, physical conditioning & wellbeing etc.
…
Next Generation Biometric Smart Shirts
Hexoskin supported the evolution of its 100% washable industry-leading Hexoskin Smart Garments to offer an easy and comfortable solution for continuously monitoring precise data during daily activities and sleep. Hexoskin is a machine washable Smart garment, designed and made in Canada that allows precise long-term monitoring of respiratory, cardiac and activity functions simultaneously, as well as sleep quality.
Users are provided access the Hexoskin Connected Health Platform, an end-to-end system that supplies the tools to report and analyze precise data from the Hexoskin & third-party body-worn sensors. The platform offers apps for iOS, Android, and Watch OS devices. Users can access from anywhere an online dashboard with advanced reporting and analytics functionalities. Today, the Hexoskin Connected Platform is used worldwide and supported thousands of users and organizations to achieve their goals.

The Hexoskin ProShirtcomes with built-in textile ECG & Respiratory sensors and a precise Activity sensor. The ProShirt works with the latest Hexoskin Smart recording device to offer uninterrupted continuous 24-hour monitoring.
Today, the Hexoskin ProShirt are used by professional athletes for performance training, police & first responders for longitudinal stress monitoring, and patients in clinical trials living with chronic cardiac & respiratory conditions.
Connected Health & Software Solutions
Hexoskin provides interoperable software solutions, secure and private infrastructure and data science services to support research and professional organizations. The system is designed to reduce the frequency of travel and allow remote communication between patients, study volunteers, caregivers, and researchers. Hexoskin is an efficient and precise solution that collects daily quantitative data from users, in their everyday lives, and over long periods of time.
Conscious of the need for its users to understand how the data is collected and interpreted, Hexoskin early took a transparent approach by opening and documenting its Application Programing Interface (API). Today, part of Hexoskin’s success can be attributed to its community of developers and scientists that are leveraging its Connected Health Platform to create new applications and interventions not possible just a few years ago.
Future Applications—remote health to space exploration
Since 2011, Hexoskin collaborated with the Canadian Space Agency on the Astroskin, a cutting edge Space Grade Smart Garment, now used in the International Space Station to monitor the astronauts’ health in Space. The Astroskin Vital Signs Monitoring Platform is also available to conduct research on earth.
Hexoskin hopes to bring the innovations developed for Space and its Hexoskin Connected Health Platform to support the growing need to provide patients’ access to affordable and adapted healthcare services remotely. Future applications include healthcare, chronic disease management, sleep medicine, aging at home, security & defense, and space exploration missions.

Finally, I noticed that the researchers on this project were from the Schlegel-UW [University of Waterloo] Research Institute for Aging. I gather this was all about aging.
Receiving an email newsletter from a local group about social robots has given me an excuse to write up a few ideas I’ve been mulling with regard to older adults, stereotypes, and the rush to innovate with ‘elder care’ technology.
A request for volunteer participants for a social robot survey
It seems that in the near future seniors in Vancouver could have a real life experience with an ‘artificial friend’ if these folks have anything to do with it. In a March 2021 Vancouver neighbourhood newsletter for seniors (specifically, the West End Seniors Network [WESN] newsletter), there was a notice for participants in a research project, Note: Some formatting changes have been made but text has not been altered,

Before the survey was shut down, I tried contacting the researcher, Dr. Jill Dosso by email with some questions and had no success either time. So, I participated in the survey, which I found to be a little disconcerting.
If memory serves, I was asked about how powerful I felt relative to the three robots (all animal-like) featured in the survey. These and other puzzling (to me) questions meant I took significantly longer than 20 minutes to complete the survey.
Are my responses truly anonymous?
I did find some additional information in the consent form such as the project name. Also, the form stimulated a question about my data. Here’s the consent form,

There are stories online about how technically skilled people can use anonymized data to reveal your identity; I read one such story years ago on Slate.com. The journalist had gotten a friend to agree to the test and then approached a tech specialist. The surprise was that the specialist managed to crack the friend’s identity in under 24 hours.
Universities and hospitals are high value targets and this survey was run by university researchers one of whom is jointly associated with a local hospital. BTW, over the last 18 months, I’ve been alerted by both universities I attended that my data privacy has been breached.
It would be good to know more about how my data is being protected. As for the five year time limit, is the data designed to self-destruct like it does on Mission Impossible?
Two SOCRATES?
The first SOCRATES project was in the European Union and ran from 2017 to 2019. The research topic was focused on social robots with a special emphasis on their use in eldercare.
The second SOCRATES (SOcial Co-creation of Robotic Aging TEchnologieS) project (the survey somehow informs this project) is Canadian and currently ongoing. The research topic (from Julie Robillard’s New Frontiers in Research 2018 Exploration Grant summary‘ enter Julie Robillard’s name in the ‘Filter items’ field to quickly access the project) is focused on “Improving independence and quality of life for older adults can be realized by complementing human care with robotic assistive technologies.” The SOCRATES (two) grant runs from 2018 – 2021.
Getting back to the matter at hand, the survey I took seemed more focused on people with dementia than older adults in general and how any of it would result in ‘co-creation’ is a mystery to me.
Where are the older adults and ‘co-creation opportunities’?
As far as I can tell, the answer to both questions is ‘they are nowhere’ visible as part of this project. Yes, a few people associated with AGEWEll; Canada’s aging and technology network (mentioned at the of the survey) are probably over the age of 50 (or even 60) but there doesn’t seem to be a concerted effort to integrate older people into that organization or SOCRATES (Canadian version) for planning purposes.
As for the older researchers, they tend to be professionals in the field of geriatrics, gerontology, robotics, assistive technologies, etc. So, they’re still working and they have spent years inside echo chambers and other self-reinforcing environments.
Years ago I came across the term ‘downstream public consultation’. This survey is an example of that; the social robots have been designed and the participant is asked how they feel about it. The information gathered may or may not be used but it’s not integral to the social robot project itself.
There is also ‘upstream public consultation’ but that is much more work and more difficult. It does mean that the objects of the research (in this case, older adults) could have some say in the design and implementation of the programmes and/or technologies.
Old age has much in common with childhood and/or with poverty. The default position is that you are not treated as someone with a valid opinion or idea. Someone is always trying to research you and, more often than not, help you by getting to you to do something whether you like it or not.
It’s often well meaning research but you are always aware that you are the object and the one with all of the social capital/clout is the researcher. I am of course describing a power imbalance.
The power imbalance always exists but it is severe where older adults, children, and the poor are concerned. I don’t know that it can ever be wholly resolved but I do wish researchers would acknowledge its presence in the materials describing their research. For example,look here.
Blind spot: when do you think the internet was invented?
I find it fascinating that one of the concerns often expressed and almost always assumed in the gerontology/geriatric/artificial intelligence/robotics/telecommunications (an more) communities is that older adults are technologically/digitally illiterate.
Let’s think on this.
From Evan Andrews’ December 18, 2012 article for History television channel, “Who Invented the Internet?” (article updated October 28, 2019), Note: Links have been removed,
As you might expect for a technology so expansive and ever-changing, it is impossible to credit the invention of the internet to a single person. The internet was the work of dozens of pioneering scientists, programmers and engineers who each developed new features and technologies that eventually merged to become the “information superhighway” we know today.
Long before the technology existed to actually build the internet, many scientists had already anticipated the existence of worldwide networks of information. Nikola Tesla toyed with the idea of a “world wireless system” in the early 1900s, and visionary thinkers like Paul Otlet and Vannevar Bush conceived of mechanized, searchable storage systems of books and media in the 1930s and 1940s.
Still, the first practical schematics for the internet would not arrive until the early 1960s [emphasis mine], when MIT’s [Massachusetts Institute of Technology] J.C.R. Licklider popularized the idea of an “Intergalactic Network” of computers. Shortly thereafter, computer scientists developed the concept of “packet switching,” a method for effectively transmitting electronic data that would later become one of the major building blocks of the internet.
The first workable prototype of the Internet came in the late 1960s with the creation of ARPANET, or the Advanced Research Projects Agency Network. Originally funded by the U.S. Department of Defense, ARPANET used packet switching to allow multiple computers to communicate on a single network.
…
Did you notice the date I highlighted? (Andrews does an excellent job of summarizing the events that led to the internet and the world wide web and it’s not a long read, “Who Invented the Internet?“)
The stereotype that almost all older adults are technologically/digitally illiterate
As I and others have noted, people were developing and building the internet some fifty years ago. Following on that thought, it seems certain that some of these people are now older adults.
Not everyone was a pioneer ‘building’ the internet but there were many, many people whose jobs were automated early (in the 1970s and 1980s) and required to use computers. Strangely, these early adopters were not the professionals, it was their office staff (clerks and secretaries).
The word ‘required’ means that older office staff needed to learn how to use these systems if they wanted a pension.
I’ve described two assumptions that are often made. (1) Older people are technologically/digitally illiterate. (2) Professionals jumped to learn new technologies. And, since professionals were often men in the 1970s and 1980s, here’s no. (3) Men are the most tech savvy.
The assumptions are not necessarily incorrect but they are problematic when applied thoughtlessly as a stereotype for an entire population.
(I have commented on the ‘age and tech savvy’ assumption elsewhere, most notably in my March 8, 2021 posting (scroll down to the ‘Older generation has less tech savvy’ bullet point, about 60% of the way down).
Is loneliness in older people different than loneliness in youth?
I haven’t seen any research that suggests there’s a difference in loneliness at different stages of one’s life meaning I have missed it or, perhaps, the question hasn’t been asked.
It’s striking to me that all of the research I’ve seen on social robots is focused on seniors and assuaging their loneliness. Suggestions for young people tend to other, more people-oriented or pet-oriented solutions. Could social robots for seniors lead to greater isolation from society?
In the SOCRATES research summary on Dr. Julie Robillard’s Neuroscience, Engagement, and Smart Tech (NEST) Lab research page, there’s this, “… A recent systematic review of controlled trials analyzing the impact of social robots on the well-being of older adults suggests [emphasis mine] that social robots can improve nine quality of life outcomes, including reducing loneliness, stress and anxiety. [emphasis mine] …”
I appreciate the delicacy of using the word ‘suggests’, meaning that based on the previous trials, these researchers can’t conclude with certainty that a social robot will reduce loneliness, etc.
Final thoughts
The researchers never to think to explain why these social robots are pet-like rather than one of the other types. What was striking to me was that the survey didn’t have a single question about play or teaching the robot how to do things or modifying/customizing the robot.
Getting back to stereotypes and older people, there’s nothing terribly wrong with the survey or the research intent; I just wish that a little more imagination and thought had been put into questioning some of the assumptions for the Canadian SOCRATES project and others of its ilk. And if the researchers did question some of the common assumptions about older people, I wish that they had made that clear in the research summary and/or the survey materials.
In recent years, there has been a rise in cynicism about many traditionally well-respected institutions – science, academia, news reporting, and even the concepts of experts and expertise more generally. Many people’s primary – or only – exposure to science is through biological or health science, especially during the COVID-19 pandemic.
In health research, rising cynicism has spawned the anti-vaccine movement, and a growing reliance on advice from peer networks rather than experts. In part, such movements are fuelled by several examples of provably false, so-called “scientific results,” coming about either through fraud or incompetence. While skepticism is crucial to science, cynicism rooted in a lack of trust can devalue scientific contributions.
In her lecture webcast, physicist Catherine Beauchemin will explore the erosion of trust in health research, presenting examples from influenza and COVID-19. …
Two essential ingredients of the scientific method are skepticism and independent confirmation – the ability to glean for oneself whether an established theory or a new hypothesis is true or false. But not everyone has the capacity to perform the experiments to obtain such a confirmation.
Consider, for example, the costs of constructing your own Large Hadron Collider, or your ability as a non-expert to critically read and understand a scientific publication. In practice, acceptance of scientific theories is more often based on trust than on independent confirmation. When that trust is eroded, issues emerge.
In her November 4 [2020] Perimeter Public Lecture webcast, Beauchemin will highlight some of the issues that have eroded trust in health research, presenting examples from influenza and COVID-19. She will show why she believes many of these issues have their root in the fact that hypotheses in health research are formulated as words rather than mathematical expressions – and why a dose of physics may be just the prescription we need.
Mayurika Chakravorty at Carleton University (Department of English) in Ottawa, (Ontario, Canada) points out that the latest pandemic (COVID-19) is an example of how everything is connected (interconnectedness or globality) by way of science fiction in her July 19, 2020 essay on The Conversation (h/t July 20, 2020 item on phys.org), Note: Links have been removed,
In the early days of the coronavirus outbreak, a theory widely shared on social media suggested that a science fiction text, Dean Koontz’s 1981 science fiction novel, The Eyes of Darkness, had predicted the coronavirus pandemic with uncanny precision. COVID-19 has held the entire world hostage, producing a resemblance to the post-apocalyptic world depicted in many science fiction texts. Canadian author Margaret Atwood’s classic 2003 novel Oryx and Crake refers to a time when “there was a lot of dismay out there, and not enough ambulances” — a prediction of our current predicament.
However, the connection between science fiction and pandemics runs deeper. They are linked by a perception of globality, what sociologist Roland Robertson defines as “the consciousness of the world as a whole.”
…
Chakravorty goes on to make a compelling case (from her July 19, 2020 essay Note: Links have been removed),
In his 1992 survey of the history of telecommunications, How the World Was One, Arthur C. Clarke alludes to the famed historian Alfred Toynbee’s lecture entitled “The Unification of the World.” Delivered at the University of London in 1947, Toynbee envisions a “single planetary society” and notes how “despite all the linguistic, religious and cultural barriers that still sunder nations and divide them into yet smaller tribes, the unification of the world has passed the point of no return.”
Science fiction writers have, indeed, always embraced globality. In interplanetary texts, humans of all nations, races and genders have to come together as one people in the face of alien invasions. Facing an interplanetary encounter, bellicose nations have to reluctantly eschew political rivalries and collaborate on a global scale, as in Denis Villeneuve’s 2018 film, Arrival.
Globality is central to science fiction. To be identified as an Earthling, one has to transcend the local and the national, and sometimes, even the global, by embracing a larger planetary consciousness.
In The Left Hand of Darkness, Ursula K. Le Guin conceptualizes the Ekumen, which comprises 83 habitable planets. The idea of the Ekumen was borrowed from Le Guin’s father, the noted cultural anthropologist Arthur L. Kroeber. Kroeber had, in a 1945 paper, introduced the concept (from Greek oikoumene) to represent a “historic culture aggregate.” Originally, Kroeber used oikoumene to refer to the “entire inhabited world,” as he traced back human culture to one single people. Le Guin then adopted this idea of a common origin of shared humanity in her novel.
..,
Regarding Canada’s response to the crisis [COVID-19], researchers have noted both the immorality and futility of a nationalistic “Canada First” approach.

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.
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.,

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 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.

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.
