    Jennifer Grey and Patrick Swayze in 1987’s Dirty Dancing. Online apps have become essential links for romantic liaisons during the pandemic lockdown, but don’t neglect those dance moves.

    Almost every millennial has been here: it's about 11 pm on Friday night, maybe Saturday. One hand fumbles through a bowl of greasy popcorn, the other viciously swipes through a stream of unremarkable faces, while on the flat screen Meg Ryan professes her love to Tom Hanks in "Sleepless in Seattle," or was it "You've Got Mail" this time? 

    Pre-COVID, online dating was a casual pleasure. With the dawn of physical distancing and tightened social circles, it’s become a necessity. Apps like Tinder, OkCupid and Bumble have become essential to singles across the planet, hungry for connection amidst the new normal.

    But can we find true love without physical connection?

    Michael Winterdahl says albeit it’s not impossible to find love in a socially distanced era, it poses its own unique set of challenges.

    "Frankly, individuals may worry about their relationships as they've gotten through everything they needed to talk about,” he says. “Next thing you know you're discussing your favourite fruit."

    Winterdahl is an Associate Professor in Neuroimaging at Aarhus University in Denmark. His research, based at its Department of Nuclear Medicine and PET Center, focuses on the neurochemical oxytocin – also known as the "love" or "cuddle" hormone. 

    For the last decade, the role of oxytocin has been relatively well understood with regard to pregnancy and maternal behaviour, where it plays a pivotal role in not only inducing labour but establishing a strong bond between mother and child shortly after birth. However, Winterdahl explains oxytocin can also play a role in the development of romantic relationships, helping us form bonds with our partners. 

    "It comes like a burst; it gives us that 'kick,' that ‘spark,’ which drives us to be social.

    When we meet that unique someone, oxytocin, amongst several other neurochemicals, begins flooding the brain. 

    "Your entire neurochemistry is going off like fireworks!” Winterdahl says. “Oxytocin, dopamine and pleasure hormones like endoopioids (endorphins) are all firing off in succession." 

    Breaking this process down, Winterdahl explains that oxytocin will link into other neurochemicals such as dopamine – which is associated with learning and rewards – because, we are effectively learning about someone. This, in turn, drives us to be interested in the person and feeds into our innate reward circuits.

    The human brain in love can do some crazy things. We do things that seem a little dangerous, like riding a rollercoaster, to drive us closer together. These thrill-seeking activities cause a massive release of hormones and force us to rely on our partner, which creates another burst of oxytocin, bringing us closer together. 

    Winterdahl says that it’s unclear if seeing someone over a screen can produce these same bursts in oxytocin. But moving dating to an online mode could provide some social value, since it forces us to engage the cognitive portions of our brain before our physical desires.  

    "Essentially, it's shifting our learning from the physical part of relationships to things we may not tap into on a standard first date such as one's beliefs and values,” he says. “People often tend to forget about social compatibility and worship the feeling of being in love."

    "Maybe, years from now, we will be able to look at the marriage-divorce statistics of couples who began with discussing their favourite fruits. They could be onto something."

    But what about that certain Je ne sais quoi, that feeling that draws us to the man or woman across the bar? Can we find love at first swipe? Dating apps, like Tinder and Bumble, might help us cross paths with a beautiful stranger - but Winterdahl says the value of physical interaction, particularly dancing, should not be underestimated.

    When we meet someone, so much of what we are experiencing is happening at an unconscious level and ties back to pure evolutionary biology. For instance, a preference for your partner's smell indicates that your immune systems are compatible. That is, we are genetically designed to prefer the scents of partners who have immune systems different from our own. 

    Winterdahl explains this because if we were to procreate, our offspring would carry different genes from both parents, giving them an immunological advantage. This theory has garnered so much traction that individuals who have amassed a bad case of carpal tunnel from swiping can actually try "Smell Dating." This is a mail-order match-making service that gives you the opportunity to sniff the dirty t-shirt – and unique scent – of your potential mate before meeting them. 

    So, where does dancing come into play? Well, Winterdahl explains that nervous system compatibility is essential to the success of a couple. When dancing with someone, we are tapping into their nervous system; it is as close as we can get to being in touch with someone's brain without physically entering it. 

    Now, no one is saying you need to master the full Dirty Dancing lift. But as pandemic restrictions ease, it might be worth masking up for a quick tango.

    The demands of their profession and society’s expectations put enormous pressure on physicians, leading to mental illness. Photo:  www.freepik.com and https://wallpapersafari.com/w/OTsxzw


    With COVID-19 cases soaring and more workload than doctors can handle, their lives are at risk by not only from the virus but by their own hands.

    In late April 2020, the United States COVID-19 case count had just topped one million. In New York, one of the disease’s epicenters, Dr. Lorna Breen, medical director of the emergency department at a Manhattan hospital, died by suicide. Her death is likely a tragic consequence of the pandemic, but physician suicide has been an ongoing epidemic of its own for some time.

    Studies show a high prevalence of physician suicide, something that could be worse under the shadow of the pandemic. 

    Dr. Christine Moutier of the University of California estimates about 400 doctors die from suicide each year in the United States; the highest rate of any of the professions. In Canada, a study of 3,213 physicians found that 20 per cent  and 29 per cent of male and female physicians, respectively, experienced depression. The same report concluded physicians are about three times more likely to commit suicide than the general population.

    The film “Do No Harm” by Robyn Symon brings light to this “hidden epidemic” by suggesting that a reform of the medical system needs to be made. 

    Just from the trailer of the film, it is seen that sleep deprivation and long hours of work make medical errors more likely. Notably, in the United States, 250,000 patients die per year due to medical error. Thus, a doctor’s burnout is not only a risk to themselves, but also may pose risks to their patients.

    A tremendous amount of responsibility and competency is expected in a physician’s career. It is no secret they have a crushing workload. Reaching medical school is becoming more competitive; staying in school and competing for residency programs is the same. The compulsion to overachieve and stay on top of responsibilities can be daunting.

    Just getting to medical school takes great discipline: endless hours of studying, superior time management skills, and a bar for success that is raised every year due to an increasing number of applicants and competition. Once in medical school, competing for the very few spots in residency programs can be even more stressful. 

    The pressure is on. Burnout can soon follow. 

    What happens to the physician that seeks help? A diagnosis of a mental health problem carries a stigma. It is thought to reflect poorly towards the physician’s capabilities. This ​belief drives physicians to avoid seeking self-help treatments. 

    “We have a system where people [physicians] fear punitive consequences if they get help”, Dr. Moutier says. 

    Research led by Dr. Katherine Gold of the University of Michigan Medical School looked at data from 2,100 respondents. Her work shows that among female physicians, half reported fear of stigma as a reason for keeping quiet about their mental illness and only six per cent reported their mental illness to state licensing boards. This shows that physicians are reluctant to share information or to reach out for mental health treatment as their confidentiality would be compromised once reports are made. 

    Self-care measures are starting to be included as part of the medical education system, but as the alarming numbers of suicide suggest, there is an even longer road ahead when addressing physician suicide.

    Adding to this is COVID-19 creating an environment that is completely different, unfamiliar, and new in its nature. 

    McGill University’s faculty member, Dr. Jason Harley, suggests there needs to be new studies just looking at how health care professionals are dealing with the pandemic and what works in order to support doctors during the time where “we need them at their best.” 

    COVID-19 brought a time of crisis. It also exposed how important our doctors are to all of us. 

    Doctors are there for us. We must be there for them.

    Photo caption: Residents of long-term care facilities in Canada have been disproportionately affected by COVID-19 due to a dysfunctional care system and a lack of action to combat the spread of infection.

    To date, a staggering 81 per cent of COVID-19 deaths in Canada are attributable to long-term care facilities. This not only reflects the way we knew COVID-19 could ravage the elderly, but also reveals a care system in shambles, to which eyes have been long averted.

    The devastation COVID-19 could inflict on residents of long-term care facilities should not have been surprising, given the vulnerability of older populations to the virus. Alarming fatality rates had already been reported at outbreaks in other care facilities such as in Wuhan, China.

    Canada’s first outbreak in a long-term care facility came in early March in British Columbia. Swift measures were taken to reduce the spread of the virus by providing adequate personal protective equipment to staff.  Measures were taken to reduce the number of healthcare providers working in multiple facilities, a circumstance known to exacerbate transmission. Due to decisive action, COVID-19 deaths in long-term care facilities in British Columbia remain relatively low, numbered at 115 as of June 11th.

    Other provinces have fared far worse. Quebec and Ontario were slow to instruct care facility workers not to work at multiple care homes. By then, the crisis was well underway. Officials focused on making sure hospitals had the resources they needed to combat the flood of cases expected to require hospitalization or critical care. Meanwhile, lack of action in long-term care facilities in Ontario and Quebec resulted in needlessly high death tolls.

    Quebec has seen more than 2,500 deaths in long-term care facilities and Ontario 1,500. At least 273 homes in Quebec have seen outbreaks to date, along with at least 300 homes in Ontario. In response to the provinces’ pleas for help, more than 1,600 members of the Canadian Armed Forces were dispatched to long-term care facilities throughout the two provinces in order to curb an ultimately avoidable crisis that has been years in the making.

    For many family members, the pain of bereavement has been met with the unknowable question of whether there was peace in the passing of their loved ones. Recent military reports in Ontario homes of neglect of and aggression toward residents, as well as of residents having been heard crying out for help for hours and found left in soiled diapers. These reports have led to inquiries into COVID-19 deaths in these homes and the seizing of control of five Ontario facilities by the government.

    It was a deeply flawed system rife with vulnerabilities, needing only a simple trigger to topple the initial domino in a deadly cascade. Long-term care facilities with old infrastructure, limited capacity for social distancing, and a high level of contact between the residents, health care providers, and visiting family, were from the outset not in a position to effectively handle a viral pandemic. Many health care providers were also working at multiple facilities and being paid low wages with few benefits and no sick pay, directly contributing to the surge in cases.

    Changes to the care system have been promised, though few have been implemented. Low rates of facility inspection, a lack of care standards, and poor working conditions have ultimately exacerbated neglect. COVID-19, coupled to a shocking lack of response given numerous warning signs, opened a concealed crack in a care system into a chasm into which the innocent elderly fell.

    While British Columbia has been better able to mitigate the spread of infection, three care homes have also been placed under the jurisdiction of the provincial government due to insufficient care.

    At the least, residents of long-term care facilities should be able to pass the remainder of their years with care and a consideration of their dignity. We cannot know just how many of our elderly were stripped of the respect and attentiveness owed them as members of a society, and, more fundamentally, as members of humanity.

    It is an injustice that a virus long warned to most severely afflict the elderly should have been allowed to spread disproportionately through their care homes. For all of the damage the pandemic has precipitated, longstanding inaction gave way to preventable tragedy.

    What does mental health look like in the age of COVID-19? It’s still too early to tell. Photo by Serkan Göktay, pexels.com

    The number of Canadians expressing increased levels of anxiety and depression has quadrupled since the arrival of COVID-19, according to a recent report by Mental Health Research Canada.

    Ontario responded by making therapy free for people with anxiety or depression. Minister of Health Christine Elliott explained that individuals will be assessed by a “trained mental health clinician” and then “offered a therapy program that best addresses their level of need.”

    Research is underway to better understand the impact of the pandemic on the mental health of Canadians. The Centre for Addiction and Mental Health (CAMH) in Toronto regularly updates its survey numbers online.

    CAMH found that 25 per cent of respondents report moderate to severe anxiety levels. Women, people with children under the age of 18, and younger adults (aged 18-39) are more likely to feel anxious and depressed during COVID-19. People with a job that exposes them to high risk of infection are also more likely to have high levels of anxiety. Job loss also negatively affected people’s mental health.

    “This is the first of a series of surveys,” explains Hayley Hamilton, a senior scientist in the Institute for Mental Health Policy Research at CAMH. “We asked a series of questions, such as ‘To what extent are you worried about the impact of COVID-19 on your personal finances, about getting COVID-19?’”

    Hamilton says these questions help link COVID-related events to the person’s mental health at the time. As data rolls in from proceeding surveys, she is getting a clearer picture of how events of the day are affecting people’s wellbeing.

    People have been dramatically affected by social isolation and overall uncertainty of what is to come. 

    “We have to be on the lookout for changes in how the population is adjusting,” Hamilton said. “As we re-open, what are people experiencing? Are anxiety levels going down? Are people drinking less? We’re hoping to see reductions in loneliness as people re-engage on a personal level with others.”

    More information is needed on the mental health impact of COVID-19 in Canada. However, research from China offers insight into what we might expect. Just days before the World Health Organization declared COVID-19 a pandemic, scientists in China began surveying populations for psychological distress.

    Cuiyan Wang, a researcher at the Institute of Cognitive Neuroscience at Huaibei Normal University, measured the connection between the pandemic and people’s mental states. Results of the  study are published in the International Journal of Environmental Research and Public Health. Wang and colleagues collected data on how people were coping just two weeks after the initial outbreak in China, one day after the WHO declared the virus and international public emergency.

    The study examined 1,210 respondents from 194 cities. Of this population, 53.8 per cent reported a moderate to severe psychological impact score. In a follow-up study a month later, Wang found that people felt less distressed as the government took action to contain the virus. Most people surveyed were concerned about their family contracting the virus. They also were more likely to report anxiety if they were feeling physical symptoms associated with the virus.

    Jianyu Qiu and a team from the Shanghai Mental Health Center shed additional light on the link between COVID-19 and mental health in China. Their study, published in March, analyzed 52,730 survey responses. Of these, 53 per cent reported a moderate or severe psychological impact from COVID-19. Migrant workers experienced the highest levels of distress. This was due to concerns about virus exposure when returning to work, reduced work hours, and reduced income. People over the age of 60 were also among the most vulnerable to distress, as COVID-19 is particularly lethal to this age group. The study also found that women were vulnerable to distress and more likely to develop post-traumatic distress disorder. This suggests that COVID-19 will adversely affect the mental health of some groups more than others, particularly if they are more at risk of infection.

    Hamilton’s research reveals that women, people with children, and people who have lost their job are taking the brunt of psychological distress in Ontario. But some populations remain unaccounted for.

    So far in the province, 80 per cent of COVID-19 deaths have occurred in long-term care.  In Toronto, the five most-affected neighborhoods are more likely to have low-income, racialized, and immigrant populations. The pandemic is also adversely affecting homeless shelters’ ability to provide adequate support to people on the street—a population already vulnerable to physical and mental health conditions. More research is necessary to determine how these peoples’ mental health are affected by the increased risk of infection and death.

    A tiger paces in its cage at Winnipeg's Assiniboine Park zoo. A PinP photo.

    A study just published in the journal, Facets, begins positively enough. It acknowledges that members of Canada's Accredited Zoos and Aquariums (CAZA - the private, non-profit charity representing thirty such institutions), do try to be leaders in researching this field and, that they do take part in programs aimed at species survival by breeding animals in captivity, then re-introducing them into the wild.

    And on its own website,  CAZA claims, "We are behind some of the most remarkable conservation success stories. This includes, bringing species such as the Black Footed Ferret and the Vancouver Island Marmot back from the brink of extinction,” for example. 

    However, in some key areas, the researchers (a team of two biologists from Laurentian University in Sudbury) suggest, CAZA and its members are falling short. 

    Zoos and aquariums could be "important resources in mitigating biodiversity loss. And the credibility of zoos as conservation organizations can only be enhanced by the production of peer-reviewed science in this field."

    Yet, while CAZA members are turning out more such research (still significantly less than their US counterparts and most in "zoo-centric" journals), most are not on the topic of biodiversity conservation at all, but on veterinary science, instead. 

    "Few studies have explored their contribution to biodiversity conservation efforts and research productivity in general." 

    Increasing collaboration with academic institutions would be one way for CAZA to overcome that shortcoming. So, “It is puzzling that collaborations between these groups are rare. Academics can use the unique environment zoos and aquariums provide for studying species, whereas academic research based on field observations may increase the success of reintroduction efforts led by zoos and aquariums.”

    This new research comes to light against the backdrop of extinctions hanging over tens of thousands of Earth's wild species, “ due to widespread degradation of global ecosystems caused by humans.”

    Global climate change strike. Photo by Markus Spiske on Unsplash

    You could be forgiven for thinking that the world has forgotten all about climate change in the face of the immediate, made-for-Hollywood crisis of COVID-19. Commentators and climate scientists clearly feel the neglect [1] and in response they’ve generated their own minor epidemic of articles and blogs comparing the pandemic to climate change.

    These commentaries have appeared in forums as varied as Yale Environment 360 [2], World Economic Forum [3], The Conversation [4, 5], and the CBC [6]. They draw loose parallels between the dynamics of climate change and COVID-19, and conclude that humans only respond to a threats after it’s become a crisis [6]. Some go further, asserting that our handling of the pandemic holds lessons for how we can deal with climate change. One claims our collective response to Covid-19 "proves" we can act rapidly to reduce global warming [5].

    Such hopeful comparisons seem overdrawn.

    Climate change and the COVID-19 pandemic are different types of crises and they develop at different speeds. Thinking about them triggers different psychological reactions. Both are complex problems, but in scale and complexity, the challenge of climate change greatly exceeds that of COVID-19. These differences lead to disparities in the ability (and willingness) of governments and individuals to influence their outcomes. In fact, our response to the virus may teach us more about how not to tackle the climate crisis than about how to address it.

    Speed meets psychology

    Relative speed is the most obvious variable separating COVID-19 from climate change. The virus surprised the world with its rapid onset and the breakneck pace with which it challenged and sometimes overwhelmed national health care systems. Climate change, by contrast, is a slow-burn crisis, at least from the human point of view. The policy response to climate change has been even slower.

    Our approach to climate policy could be compared to the pre-World-War-II appeasement of Hitler by Britain’s government. Throughout the 1930s, the Brits continued hoping for the best while conspicuously failing to prepare for the war everyone knew was coming. Does that sound like the last 30 years of climate negotiations to you?

    With COVID-19, however, war has arrived. The Blitz of consequences is upon us. The emergency could not be clearer. People are dying and our medical defenses are stretched to the breaking point. Governments must react.

    The speed and immediacy of a crisis directly affects our psychological response to it. COVID-19 could kill you by this time next week. It’s the sabre-tooth tiger hidden in the grass, which triggers our deepest and most ancient fears. Collectively, we’re fighting it with everything we’ve got. Individually, we understand the need to avoid the existential threat. So, most of us cooperate with public health measures, hide out in our apartments, and practice social distancing.

    By contrast, psychological barriers to climate action hinge on people seeing it as an abstract problem whose consequences always lie somewhere in the future. These barriers are personal, collective, and political. They’ve managed to thwart policies and actions to combat climate change for the last 30 years. The psychologist Robert Gifford calls these “the dragons of inaction” [7]. The dragons include ignorance of consequences and causes of climate change, numbness in the face of its all-encompassing complexity, misunderstanding scientific uncertainty, and of course, good old denial.

    Complexity and management

    The emergency response to COVID-19 is unprecedented and has jolted the global economy. Managing the health of infected patients is medically and administratively complex. However, the pandemic presents us with a well-defined, singular challenge. We understand its characteristics and can tackle it with a fairly limited set of established technologies.

    Climate change, on the other hand, engages the entire Earth System in a dizzyingly complex set of positive and negative feedbacks involving the biosphere, water and weather, ocean currents and ice, atmospheric dynamics, and the human economy. The technologies, policies, and long-term strategies needed to mitigate climate change are quite different to those needed to resolve COVID-19. Some of them have yet to be invented.

    Which brings us, inevitably, to the issue of control. Our success at controlling the spread of the pandemic has been patchy, to say the least. But in principle we could have limited the spread of the virus with tighter border controls, more resilient health care systems, and better communications.

    Climate change is a borderless, planet-wide challenge that demands extraordinary international cooperation. Such cooperation may not currently be geopolitically feasible [8]. And, speculation about geoengineering notwithstanding [9], many aspects of the global climate and carbon cycles will forever be beyond human control. Meeting this global challenge requires a wholesale transformation of our economies, of society, and our relationship with the Earth. It’s a fact many political leaders still seem unwilling to face.

    Lessons learned?

    A few encouraging lessons from COVID-19 might be applied to climate change. We have rediscovered that when the chips are down, we can take extreme action to tackle a crisis. We now understand there’s a critical time lag between the causes (viral transmission, latent cases) and effects (spikes in mortality, overwhelmed health systems) of COVID-19. The USA and UK discovered, belatedly, that procrastination during this time lag would only make the crisis worse.

    Climate scientists understand there are multiple such lags between cause and effect built into the climate system. We must not be forced to experience the consequences of these lags for climate change, because a few more years of procrastination will close the narrow window of opportunity that remains for effective action.

    Sadly, it seems the potential lessons of COVID-19 for climate policy could be lost in the rush to restore business as usual. Many fear that our obsession with the pandemic and subsequent economic recovery could eclipse environmental concerns for years. Even as oil prices crash, the governments of the USA, Canada, and Alberta are spending billions of dollars to shore up shale oil, oilsands, and pipelines [10]. And in a mute commentary on our current priorities, the venue for a critical round of UN climate talks in November has been converted to a hospital for COVID-19 patients [1].

    Like most Canadians, I’ve been spending a lot more time at home. Looking through my kitchen window has become my favourite way to enjoy the outside world.

    Since early April, I’ve noticed a pair of red-breasted American robins coming to my backyard every day. They have a nest somewhere between my neighbour’s house and mine. Another species also visits my yard: grackles, recognizable by their iridescent blue heads and black bodies.

    These ones appear to have some aggression issues with the robin pair: Most interactions between them end in one bird chasing away the other.

    This is common, explained Tony Beck. He’s an experienced birder, wildlife photographer, tour guide, and member of the Ottawa Field Naturalists Club (OFNC).

    Beck has been interested in wildlife since he was a child, whether he was fishing with his father in Eastern Ontario or exploring Lanark County at his uncle’s.

    “I felt good being surrounded by nature and wildlife,” he says.

    In the 80s and 90s Beck became more involved with the naturalist community and made his work a full-time career. His wildlife tour and photography business, Always an Adventure, is based in Ottawa, Ont.

    Beck says after spending their winters in the United States, grackles and American robins fly back to the Ottawa area in mid-February.  When they return, they establish territory.

    “They’re going to start working at the nest straightaway,” he says. “You see them paired off and walking around.”

    As for the backyard robins? Beck suspects they might already have fledged young who are almost ready to leave the nest.

    Grackles follow a similar pattern. A pair have nested in the backyard across from mine.

    Not all is peaceful between the birds. American robins belong to the thrush genus (Turdidae), while grackles are blackbirds (Quiscalus).

    “They're not that closely related but they do occupy the same type of niche,” Beck says. “So, there are some territory territorial disputes, maybe for food and things like that, but they normally don't get along.”

    In fact, grackles look at other birds’ nests as feeding opportunities. Beck points out that grackles will look for eggs and nestlings.

    “They won’t think twice and they’ll rob the nest.”

    Parent robins are wary of grackles. They defend their nests and look out for each other whenever a plague of grackles is about. Ganging up in these large groups makes them much more intimidating to smaller birds. There’s a perceptible tension in the air that comes with the flapping of their black wings.

    The robin pair will chase away a stray grackle, returning to perch on the fence and breathing heavily. I’ve seen grackles steal worms from the robins’ beaks.

    “This kind of drama goes on all the time,” Beck says.

    Budding birders like me can observe this behaviour in suburban areas like our backyards, or in a natural area like in Greenbelt trails (while observing proper social distancing, of course).

    Since worldwide stay-at-home orders have been put in place, news outlets across the world have reported animals coming back to cities and developed areas. Beck says they’ve always been there, “regardless of whether there’s people or not.”

    While it’s true that animals are more inclined to come out right now, they’re usually just shy and furtive when there are people out. Before the coronavirus pandemic, Beck would go outside early in the morning so he could focus on finding animals and avoid disruptive crowds.

    If you want to start looking for interesting species in your area - whether you’re walking around your neighbourhood or watching from your window - there are a few things to keep in mind.

    “People have to become sensitive to the nature of wildlife,” Beck says. He laments beginning birders and wildlife photographers pestering a bird’s nesting area or baiting predatory owls with live mice, for example, disrupting the natural learning process for many species.

    “It’s good that people are becoming interested in nature,” he says. “But please be sensitive to the animal.”

    Beck wants enthusiasts to prioritize the animals’ needs before their own and to respect the animals’ space. Observers should be conscious of behaviours that show the animal is exerting extra effort to avoid you. Leave those animals alone.

    This is where classic birder tools like binoculars and telephoto lenses come in handy, Beck says. He also recommends a field guide like the Sibley Field Guide. This way, you can observe wildlife from a non-intrusive distance and identify and distinguish different species.

    Early birders can get involved in citizen science by participating in February’s annual bird count, where people across the world go out and count different species as migration season begins.

    Even if you’ve missed this opportunity, spring is still an exciting time for naturalists like Beck. Eastern bluebirds, yellow-rumped warblers, ruby-crowned kinglets, scarlet tanagers, and black-throated blue warblers are some of the rainbow of birds he’s looking out for in the Ottawa area this spring.

    Even though the spring migration “peters out towards the end of May,” you can still look out for the birds heading to the High Arctic in early June, Beck says.

    “It’s amazing what things you can find when you start looking.”

    I toss the overpriced ground beef into my basket, my latex gloves making an uncomfortable squeak as the plastic-wrapped package leaves my hands. I'm still unsure which pill is harder to swallow. Is it the point I am wearing more personal protective equipment to do my grocery shopping than I had as a research assistant in grad school? Or that this pack of hamburger costs an hour's wage?

    With meat packaging plants in Alberta and BC scrambling to reopen after staff testing positive for COVID-19, this disruption to the beef and poultry supply chain is beginning to show at local supermarkets.

    This isn't the first time the meat supply has been disrupted by a disease.  Between 2014 and 2015, United States poultry producers had to slaughter more than 50 million chickens and turkeys because of the HPAI avian flu threat. The cull affected poultry farms across 15 states, threatening farmers' livelihoods, driving up the price of poultry, and ultimately resulting in more than 30 countries banning American poultry. The Canadian meat market isn’t immune to these challenges either. Alberta faced similar issues with the rise of mad cow disease in the mid-2000s.

    So, whether it’s due to staffing issues, or zoonotic (animal born) diseases, how do we prevent supply chain disruptions in the agriculture-meat industry?

    Future Fields, an Edmonton-based biotech company, proposes what seems like a near-impossible solution - to remove animals from the equation entirely. Founded by a group of socioeconomically motivated friends, the firm specializes in producing cell growth media. The growth media acts as the main nutrient or ‘food’ source for the cell and in turn, will be used by cellular agriculture companies to develop products such as lab-grown meat.

    Such innovations could help ameliorate supply chain issues seen in traditional agriculture. It could also free up grain for human consumption by increasing the amount of arable land for crop growth and redirecting grain supplies from animal feed.

    So how is lab-grown meat produced? Matthew Anderson-Baron, co-founder and chief scientific officer for the company, admits even he finds it a bit "sci-fi."

    Anderson-Baron completed his PhD in Cell Biology from the University of Alberta, where he also recently finished a post-doc focused on culturing stem cells to grow into tissues such as cartilage.

    "Cell agriculture can encompass any animal-derived product including milk or leather,” he says. “Meat is just the holy grail everyone is after."

    The process begins by taking a small biopsy of animal tissue. In the case of meat, this means taking a sample from the kind muscle the desired cut of meat comes from. From here, scientists isolate stem cells from the tissue and put them in specialized media (provided by Future Fields), which contains signaling factors that tell them how to develop and grow.

    “Depending on the signaling factors we give the stem cell population, we can create a variety of cell types from that single biopsy,” Anderson-Baron says. 

    Anderson-Baron admits this isn't the full equation. Some types of meat are more natural to replicate than others.

    "The most straightforward product is probably ground beef," he says, "Things like steak get a bit more complicated as the cells need to be grown on a 3D-scaffold." 

    “Replicating the authentic taste of meat requires growing more than just muscle cells.” Anderson-Baron explained.

    These muscle cells must be co-cultured with other tissues such as fat that add to the flavour of meat. Essentially, the process demands creation of a local neighbourhood of various cell types that can survive together until the finished product is fully grown. Here is where the media produced by Future Fields become essential. Companies don’t have to tweak this recipe and scale it up for production, as this has already been done.

    New technology like cell-cultured meat is definitively disruptive to the current way of doing things. Still, Anderson-Baron says there are some key advantages.

    "For one, we are controlling what the end product looks like at the cellular level,” he says. “So we can reduce things like the amount trans fats in the final product, actually making it healthier than organic meat."

    Since lab meat is produced in sterile lab environments, it reduces risk of diseases between animals held in close living quarters. This could protect not only animal health but forestall emergence of viruses like COVID-19, which traces back to a live animal market.

    The goal at Future Fields is not to replace traditional meat entirely. However, in a letter to the Lancet Planetary Health journal, a group of more than 50 scientists are calling for the world to hit our “meat peak,” by 2030 as part of climate change initiatives. They stress it is important to recognize traditional animal agriculture will no longer be able to meet global protein demands. These are on the rise as well, driven by a combination of sustained global population growth and a rise of the middle class in developing nations.

    Right now, the concept of lab-grown meat remains fairly abstract, particularly since many people are concerned about consuming what is considered natural. Despite this, Anderson-Baron is optimistic.

    "Once people can see it and it becomes more normalized, people will care about it!” he says. “But consumers care about a lot of things, cost, taste, appearance, and we can make all those factors identical to conventional meat."

    “Two physicians during the COVID-19 pandemic bridged by artificial intelligence” This cover has been designed using resources from Freepik.com and DrawKit.io


    As COVID-19 cases rise globally, one must wonder what would help ease its burden within our society. A solution is artificial intelligence. Here’s why. 

    Artificial intelligence involves using machines to mimic human learning and thinking. It is a diverse area and many applications can be implemented for specific tasks. For instance, we can use AI to teach machines to recognize specific patterns. 

    Why would this be useful?  During the current pandemic, doctors are overwhelmed by the sheer volume of cases to be analyzed. Symptoms are similar to other illnesses and cases keep piling high. Artificial intelligence can enable faster data analysis, ready to be interpreted by doctors, in effect acting as a ‘force multiplier’ in this battle against the virus.

    Why aren't we doing this already? Currently, AI has been used to accurately predict the molecular structure of SARS-CoV-2 (the virus that causes COVID-19). This breakthrough shortens the time required to find a vaccine. 

    Though applications like this have been implemented, it remains a challenge to harness AI to analyze the number of COVID-19 cases that reach a hospital daily. In addition, not all countries have the necessary technology and expertise. Some are more technologically advanced, while others are still progressing. 

    Finding a way to introduce AI globally remains unresolved since each country’s response differs by their individual health systems and relative wealth. Though measures being taken by individual countries may be enough to get through the current crisis, we should look at ways to cooperate to combat future pandemics effectively. AI could be part of the solution. 

    Right now, healthcare workers are on the frontline battling COVID 19. There are simply too many patients assigned to a doctor or a nurse. This is where AI can take its place, helping healthcare workers speed up the process of treatment. 

    AI would not take the lead. Rather, it would augment the efforts of healthcare professionals to improve efficiency. Imagine: an emergency room flooded with coronavirus cases. Staff are overwhelmed, doing multiple tasks, some urgent, some routine such as checking vitals or taking temperature. A COVID-19-specialized AI takes this data, analyzes it, and immediately delivers the results to the doctor, who uses it to inform a recommended treatment. 

    On the public health front, imagine how AI-driven analysis could support much faster COVID testing, accurately reporting cases and providing the information needed to effectively implement solutions to flatten the curve. 

    Harnessing AI could also reduce burnout for healthcare workers. With less tedious tasks to complete, more time could be allocated in taking a breather, both physically and mentally. Doctors have the highest rate of mental illness than any other profession. About 40 doctors per 100,000 die from suicide, a rate double that of the general population. The rates are even worse during this pandemic. With physicians getting less sleep and losing more patients, their mental health succumbs to feelings of hopelessness. While reducing workloads isn’t a panacea, relieving some stress with AI is a start.

    The reality is we could have been more prepared for COVID-19. We have a lot of resources to implement the next step towards technological advancement, but we don’t have the structure to make it feasible globally. Our healthcare professionals are suffering and we need better ways to support them. It is time to think about how to better implement AI to better support healthcare workers globally.

    COVID-19 conjures the spectre of the 1918-19 Spanish flu and the power of knowledge.

    Not since the Black Death of the 14th century had humanity been so ravaged, but with the Spanish flu we at least knew we were being assaulted by a microscopic enemy, not “miasmas” or “bad air.” 

    Just as understanding of disease and healthcare better equipped us to handle the Spanish flu, today’s knowledge makes us more prepared to combat our current pandemic. 

    As with past diseases, SARS-CoV-2, the virus that causes COVID-19, is an indiscriminate aggressor. It infects populations with ease, with severity largely determined by age and health status. 

    Today, backed by fortune only technological progress can bestow, scientists could quickly identify and understand the novel virus was spreading, and spreading rapidly, throughout the world. Knowing that COVID-19 is caused by a member of the coronavirus family of viruses, scientists and medical professionals could get to work developing screening tests, trying to identify therapies, and hurriedly moving toward a vaccine. 

    Modern medical understanding has been our foremost ally in the struggle against disease, but it’s an ally whose help has come only with time and incremental discoveries. 

    The first victims of the Black Death could not have understood their illness was being caused by the bacterium Yersinia pestis. They only knew what they could see: a rapid progression of blackened boils on the skin, the fever, the aches, the pains, and an almost certain descent into death.

    Many of those first affected by the Spanish Flu during its first wave in the spring of 1918 suffered only mildly, leading many experts to believe the illness too mild to be an influenza. With the second wave in the fall of 1918 came the shock of ominous numbers of deaths within hours of initial symptoms. The world took notice. 

    Though those who suffered through pandemics of the past could only wish to look to a more medically advanced society, we can look back and benefit from history’s lessons.

    We don’t need to wait to know where a disease comes from or to fully understand it to protect ourselves. Strategies of social distancing and self-isolation mitigate the spread of disease have been long employed and remain the most effective for reducing transmission. 

    Even imperfect understanding led to practices to limit the spread of plague during the Black Death. Though paramount to trade, ships arriving in Venetian ports were forced to sit at anchor for quaranta giorni - 40 days - before crews could disembark and conduct business. It is from this practice that we derive the word quarantine. 

    During the Spanish flu pandemic, people were implored not to shake hands, to avoid interaction with others and to stay indoors. Public spaces such as libraries and schools were widely shut down. In New York City, travel on public transit was staggered to limit person-to-person contact. 

    While modern medical treatments and vaccines have saved an untold number of lives, history shows the value of social distancing and isolation of those already sick in reducing disease transmission. 

    SARS-CoV-2 has upended the normalcy of our lives, is overwhelming healthcare systems, and risks devastation to the world’s economies. 

    Though we face a new pandemic, we are uniquely equipped with the lessons of history and what modern medicine can provide.  

    There is redemption in what we know.
