I’m doing neck mobilizations, a technique used to improve joint mobility and reduce pain. Today, I’m doing them by myself, sort of.
I lean my neck toward my left shoulder, stretch out my arms to the right and increase the tension of the towel wrapped around my neck. The opposing forces create an intense but comfortable stretch in my right neck muscles. I straighten my neck but keep the towel taut, then repeat the cycle 10 times.

Typically when my neck is sore, I have the experienced hands of my physiotherapist, Claire Harris, working out the knots. In a sense, I still do.
Harris explains via virtual (or video) physiotherapy, how this exercise will improve my neck range of motion and calm my nervous system. She then moves on to showing me exercises to strengthen my upper back. At the same time, I’m quizzing her.
My virtual physio sessions have been the norm since March 27, the day the Alberta provincial government announced closure of clinics to reduce the spread of COVID-19.
“The method by which we had to provide care needed to change in a very short period,” Harris says. “There are disadvantages. We’re not able to palpate structures with our hands and we lose some of the therapeutic interaction. But there are also positives: research strongly supports emphasizing active treatment, which empowers the patient.”
Some patients may even find unexpected benefits from virtual treatment. Harris says a patient who once only requested manual therapy has had to adapt to a more exercise-based treatment.
“She has taken more ownership of her recovery with guidance from myself,” Harris says. “She’s doing very well. She’s gone from minimal physical activity to exercising every day.”
Harris says the recent adjustment of peoples’ daily routines, as well as the mental stress of COVID-19, has had a significant impact on the chronic pain population.
“People who are now working from home may have suboptimal desk setups, or they’re working from the kitchen table, or maybe they’re spending a lot more time picking up after children, which can cause flare-ups.”
She explains stress alone acts as a mechanism that increases output of the sympathetic nervous system which is responsible for the “fight or flight” response. This makes nerve endings and areas of the brain more sensitive, causing pain, or the perception of pain, to increase.
Continuing to provide people with management strategies, especially for those in more severe pain, gives people an alternative to seeking emergency services. In a time when a visit to the emergency room not only means potential exposure to COVID-19, but undue stress on an already overworked healthcare system, these virtual treatments are especially valuable.
“I think initially patients are skeptical about doing an online treatment, but once they do a session, most of them are quite open to it,” Harris says.
She asks me to repeat the movements she used to assess me at the beginning of our appointment. I bring my ear toward my left shoulder with considerably more ease. It seems my range of motion has improved.
“The intent of physiotherapy is to try and customize exercises specific to the patient. We’re not a moot point just because we can’t touch you.”

While scientists around the world work toward a COVID-19 vaccine, convalescent plasma therapy may offer hope to those stricken with the disease.
With a vaccine against COVID-19 still many months away, scientists are looking to the blood of those who have recovered from the disease to develop a treatment. Evocative of vampiric imagery as it may be, this strategy is rooted in a medical treatment proven to be effective over a century of use.
The approach is to transfuse convalescent plasma, or antibody-rich plasma of recovered patients, into COVID-19 patients with active infections. The hope is these antibodies can help those patients to fight off the disease.
Detection of a virus kickstarts an individual’s immune system, stimulating it to fight infection. Antibodies to a virus are produced as part of this response, each functioning like a targeted, virus-eating Pac-Man, helping to reduce disease progression. When it works well, those suffering from mild COVID-19 can heal without any special medical intervention, save for over-the-counter medication such as acetaminophen for fever.
For patients battling more severe infections, such as those in respiratory distress requiring oxygen or ventilator support, the immunity boost afforded by convalescent plasma transfusion could mean the difference between death and survival.
Introducing the antibodies of recovered patients to those severely ill would be like giving them the temporary use of an additional, borrowed immune system - a supplemental defence to aid their own. With fewer viral particles present to continue wreaking havoc, symptoms would be reduced and the patient put on a quicker road to an otherwise uncertain recovery.
While there is no guarantee that convalescent plasma therapy will be successful for treating COVID-19, it has worked in the past to treat the Spanish flu and, more recently, SARS and Ebola.
Clinical studies of convalescent plasma therapy for COVID-19 are currently underway around the globe. A recent study out of China, the first global epicentre of the disease, reported a reduction in viral load, or the amount of viral particles in a patients’ systems, after treatment. The result was the recovery of five critically ill patients, giving scientists reason beyond mere hope to continue to pursue this therapeutic strategy for COVID-19.
Still, other aspects affecting the success of plasma therapy remain undetermined. The ideal range of days after a patient’s recovery during which to collect blood, as well as the dose, timing, and tolerability of treatment have yet to be fully teased out by scientists.
Another consideration is the quantity of convalescent plasma available for use as a treatment, and how it would be distributed. Should convalescent plasma therapy prove effective for COVID-19, supply of donated plasma would be limited, as only those infected and recovered could be donors. One recovered individual can provide enough plasma for two to four transfusion doses, with current dosing recommendations set at one per patient.
Therapy would be considered first for those severely ill with COVID-19 and suffering the kinds of symptoms that could prove fatal. Only once the most critically afflicted have been served could treatment be extended to prevent those more mildly sick from declining further into illness. Ultimately, the treatment could be offered to the elderly, immunocompromised and otherwise at-risk members of the public to boost immunity before a vaccine becomes available.
With every passing day, newly reported infections and deaths remind us that the search for a therapy that can be administered now is of critical importance. An alarming number of people remain infected, and many more will fall ill before the pandemic begins to abate.
The few recoveries attributed to convalescent plasma therapy remind us that wherein lies promise, lies hope. Despite the tragic loss of thousands that have died from this disease, there are many thousands more who have recovered. The antibodies they carry within them offer strength to aid global recovery.
Reinstating the normalcy we once knew is out of the question until we can all be armed with the protection that a vaccine affords. While we wait, those of us who have recovered may offer ourselves, in this time of crisis, to help in our shared cause.

Whether famous or obscure, Earth's wild creatures cannot escape the hand of man.
Just months ago, billions of animals, including iconic kangaroos and loveable koalas, perished in Australia's calamitous bushfires, scientifically found to have been worsened by manmade climate change. Now, researchers say, one of the Amazon's least-known species could be all but gone, too in scant decades. Its habitat is being slashed and burned to make way for agriculture.

Most of us know there are wild dogs living in remote places of the world. Australia's dingo probably leaps to mind first.
But did you also know that a cousin of the dingo (above) has been roaming quietly through vast areas of Amazon rainforests, in Columbia, Ecuador, Peru, Bolivia and Brazil for a long time?
Atelocynus microtis - the "short-eared" dog is the only canid, or mammal of the dog family, native to the Amazon.
Arguably, it's been the least-studied of any wild dog on the planet - until now.
Using the largest data base ever compiled on the species, scientists are now able to better understand the predicament it faces in its rapidly-changing home.
In the words of a research paper published this week in The Royal Society of Open Science, "Forest loss and fragmentation pose a serious threat to the species in a short time frame."
Within three generations, (six years is considered a generation to a short-ear), anywhere from 30% to 60% of its habitat will likely be lost or seriously degraded. That's because plans by local governments for large-scale agriculture, cattle-ranching and infrastructure expansion, remain in the works.
In 2011, Brazil drastically relaxed laws protecting its forests. Private landowners no longer had to protect as much as they once did. Illegal loggers were granted amnesty. By 2013, after a decade of decline, deforestation rates began to climb.
Last year, the President of Brazil, Jair Bolsonaro, fired a top scientist last year for revealing that that country's deforestation rates were increasing rapidly under his watch.
And, since last summer, Science magazine describes losses of Amazonian rainforest in Bolivia alone, as “staggring.” Much of it was due to intentional burning to clear land for crops and livestock.
It is against this grim backdrop that these new research findings have been published.
While short-eared dogs are expected to do better in areas that are protected, as many as 40% of them live in the "Arc of Deforesation," a part of Brazil where tree cover is disappearing the fastest.
Vast areas are expected to transition from forests to savannahs, or grassland eco-systems, not nearly as favourable for the carnivorous animals.
But habitat loss isn't the only threat. The dogs are catching diseases from domesticated dogs and becoming road kill after being run over on roadways.
The researchers suggest, therefore, the short-eared dog be "bumped up" the list of endangered species to a status that better reflects the danger it faces.
Then there's this chilling footnote. One out of every four mammals in the Amazon, will be losing much of their habitat, too.
Until man somehow finds a deeper appreciation and respect for our fellow creatures, these tragedies will only deepen.

If the current pandemic has taught us anything, it is to bring into stark relief just whose work is essential.
Around the world, people are coming out to yards and balconies to applaud health care workers. People have new appreciation for oft-ignored sanitation workers and grocery store clerks.
While we cheer on those who keep the wheels of society turning, let’s also spare a thought and some words of thanks for another overlooked, essential group: scientists.
Some years ago, while working at the University of Saskatchewan, I wrote a brief profile on a new faculty member, a young researcher named Darryl Falzarano. His chosen subject was an obscure (to me) disease called Middle East Respiratory Syndrome, or MERS.
Why, I wondered, was he mucking about with something that, while serious, wasn’t terribly contagious and affected populations on the other side of the world? Plus, the animal reservoir for the MERS virus was the camel – a species not often seen on the Canadian Prairies.
He explained that MERS was a coronavirus, a close relative of SARS (severe acute respiratory syndrome). SARS I knew: the epidemic had been in the news around the world. People had died; people were afraid.
MERS and SARS are zoonotic diseases, that is, they originated in animals. These diseases constitute the majority of emerging threats to human health. Know more about MERS, Falzarano said, and we know more about zoonotic coronaviruses.
I eventually left the university and lost track of Falzarano until early this March. There was an announcement that VIDO InterVac at the University of Saskatchewan was getting a sudden multi-million-dollar funding infusion from the Canadian government. A new coronavirus had gone pandemic: SARS CoV-2, which causes COVID-19. Once again, people are dying. People are afraid.
VIDO InterVac, one of the top vaccine development organizations in the country, is tasked with developing a vaccine against the threat. Falzarano leads the team.
As any emergency preparedness professional knows, when a crisis hits, there is no time to plan. The plan must be in place, the people trained, the facilities ready.
Most scientists labour in obscurity, making incremental discoveries and publishing them in journals that are largely read only by their peers. But when a crisis comes, when their expertise is needed, they are ready.
What drives scientists to do what they do? Joy of discovery? Insatiable curiousity? Desire to help society? I suspect the reasons are as varied as the people. Of one thing I am certain: scientists don’t get into it for the money. I remember being shocked to learn that a new assistant professor was being paid slightly less than me, a mere research communications officer. This, for someone who had spent at least eight to 10 years completing undergraduate, graduate, and post-doctoral education and training.
Their job was and is much harder than mine. Academic researchers must design and run their research programs, apply for and secure grants, hire and supervise graduate students, write up their research for professional journals, teach classes, and serve on university committees. To get it all done, their work schedule can be brutally long.
And every once in a while, scientists’ expertise becomes critical to the welfare of us all. Suddenly, money is no object. But no amount of funding can conjure a PhD in virology and a decade of hard-won knowledge and expertise out of thin air.
When the call comes, scientists must be ready, and they are. For this, we thank them.

In both the telling and the hearing, stories begin with people.
My passion is taking complex science transforming it into stories that engage and excite. As a strategist, I ask questions. Who are we talking to? Where are they and where do they get their information? What do they believe?
Over more than 30 years, my work appeared in weekly and national publications, broadcast and online media. For more than a decade at the University of Saskatchewan, I worked to identify and shine a light on the innovative minds and discoveries at one of Canada’s top research universities.
We live in challenging times, where innovation and knowledge are often met with rejection and disbelief. This has consequences for issues critical to our species and our environment, from vaccines and genetic engineering to energy and climate change. I believe science writers and communicators have a vital role to play.

As the ranks of the world’s professional journalists have been decimated over the past few decades, so too has their ability to report the work of science to an audience that extends beyond the scientific community itself. If you are part of that audience, you may not have noticed, because there appears to be more news about science than ever. Now the source is a new cadre of science communicators who are employed not by traditional media organizations but instead by bodies such as research institutes and universities. Yet while the burgeoning field dubbed “scicomm” continues to grow, key questions are beginning to emerge about its lack of diversity and the implications that could have for the way science is being presented to the public.
Such questions echoed through the themes of SciCommTO, a two-day conference organized by the Royal Canadian Institute for Science, a venerable body with roots that go back to the mid-19th century and some of the earliest scientific work being done in this land. About 120 participants attended this event last month at Ryerson University, where they explored a variety of topics such as how to interview researchers and frame an engaging narrative.
While much of this content amounted to a kind of vocational training, the exchanges occasionally turned contentious, as happened during a session about the professionalization of scicomm. These interactions spawned discussions offline and online that continued for several days and revealed some key challenges to be confronted.
Perhaps chief among those challenges is the fact scicomm has become a trend, a hashtag, and a community, all thanks to some savvy scientists on social media. At the same time, science communication qualifies as an academically respected social science discipline with its own research standards and evidence-based best practices.
That is why the conference, organized in collaboration with Ryerson’s own scicomm initiative SciXChange, was so valuable. It provided a space to learn and discuss evidence-based science communication, an area that currently offers few formal training opportunities in Canada. Laurentian University is the only school in Canada, and one of just a handful around the world, that offers a recognized post-secondary program in science communication.
Conference delegates, many of whom were women completing or finished their PhDs, shared that their peers outside of the science communication community saw science communication as something to “fall back on” if their academic career in science did not work out. Others, who indicated they already felt excluded from their chosen scientific work, portrayed the science communication community as a “safe space” where they belonged. And there were working scientists who suggested they were there because science communication was something impactful and fun to do in addition to their research.
There was also a small group of delegates with science communication degrees at the conference who were building careers. They voiced a concern about not being recognized as credible professionals in the field because science communication was being viewed as hobby or lacking legitimacy due to its social science nature. Additionally, one of the biggest challenges this group faces is having their work and expertise constantly undervalued because a lot of science communication hobbyists do work for free.
These perspectives were reinforced during a panel discussion, called “Canada vs. The World”, where Dominic McDonald, Head of Education at the Royal Institution in the UK, said that the vast majority of the science communicators in the UK were white, middle-class women with PhDs. In Canada, Dr. Chantal Barriault, the Program Director of the Science Communication program at Laurentian University, confirmed that the field is a monoculture reflecting this trend, putting the number of such women at 75%.
While these observations might be regarded as just one more example of how poorly the scientific community welcomes and supports women, this lack of diversity in science communication may become an even bigger concern. When the topic of professionalizing the field of science communication was brought up by Barriault, it was met with mixed responses. Her argument was that this would provide legitimacy for the work to be taken seriously and provide opportunities for anyone interested to have more training opportunities. She likened the process to the history of nursing, which was not initially regarded as a real career involving specialized skills and training, nor even compensated. It did not take on its modern value in as an esteemed part of the healthcare system until the field was professionalized.
The same problem applies to scicomm, where many practitioners do not acknowledge the evidence-based strategies that are essential to communicating and debunking myths about contentious issues, such as vaccines, climate change, and viral outbreaks. When these methods are not used, it can worsen a situation by isolating the audience or propagating misinformation.
Nevertheless, some opposed remain wary of professionalizing as a form of gatekeeping. Many scientists voiced the concerns on Twitter that if science communication is professionalized, it would be no different from how science had excluded them. Yet professionalizing science communication does not mean that scientists cannot continue sharing their research on social media or giving public lectures. In fact, professionalizing science communication would provide more resources and training opportunities for everyone interested. It would also reward both scientists and professional science communicators for their passion and work.
Currently, science communication will only continue to grow in Canada, as it should, seeing how it bridges sciences and society. To meet this demand, professionalizing the field means that it would lead to more training and projects that bring value for both scientists who want to continue doing science communication as a hobby and for those who are paving the way for a career as a professional science communicator.

Over the last few months, the United States Center for Disease Control and Prevention (CDC) has been regularly keeping up-to-date on the latest strain of coronavirus – SARS-CoV-2. The disease it causes, known as COVID-19, has spread around the globe infecting people in countries all over the world including China, Italy, the United States, and Canada.
Coronaviruses exist in both animals and humans. They are called zoonotic when they transmit between animals and humans. This family of viruses is responsible for causing a variety of diseases including cases of the common cold, as well as more severe ones like Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). In 2002-03, the SARS coronavirus transitioned into a large-scale epidemic infecting people in more than two dozen countries, resulting in more than 8,000 cases and nearly 800 deaths. By comparison, COVID-19 has now been reported in more than 100 countries.
COVID-19 spreads from person to person but can also be transmitted from contacts with contaminated surfaces or objects. Those most at risk include those with weakened immune systems, chronic medical conditions, and the elderly. Symptoms include fever, coughing, and shortness of breath. According to a recent study by researchers from the University of Texas in Austin, the new coronavirus spreads so quickly that people who have the virus can spread it before showing symptoms.
COVID-19 is causing severe social, political, as well as economic repercussions for people all over the world.
COVID-19 was first reported in December 2019 and was traced to Wuhan, China and the source is believed to be a seafood wholesale market that sold both live and slaughtered livestock.
By Dec. 31, 2019, 27 infections were reported in Wuhan forcing the Chinese government to respond. At the time, they reported cases involving a viral outbreak of pneumonia – as the exact nature of the virus was still unknown – to the World Health Organization (WHO).
Within the first two weeks of January, health officials had ruled out the presence of known coronaviruses such as SARS or MERS. Instead, Chinese researchers identified a new strain of coronavirus which would become known as SARS-CoV-2. There was speculation about the source of the outbreak. An article in the Journal of Medical Virology presents evidence that SARS-CoV-2 – or 2019-nCoV as it is referred to in the study – is a genetic combination of coronaviruses found in bats and another of unknown origin, but which likely resided in snakes, before it was transmitted to humans.
Within the next few weeks, the first death of the outbreak of the new COVID-19 disease was reported. It had already begun to spread outside of Wuhan. On Jan. 30 2020, the WHO officially declared the COVID-19 outbreak as an international public health emergency.
By February 9, the death toll in China had reached 811, exceeding the number of people who died during the SARS epidemic between 2002-2003.
More countries reported their first confirmed COVID-19 cases. This number continued to rise along with the death toll. The severity of the situation had reached a point where several countries were beginning to close down their borders.
Within the first two weeks of March, COVID-19 had been declared a pandemic by the WHO. Canada was also one of many new countries to report their first confirmed cases and as of March 20 had nearly 850 confirmed cases – most of which are located in Ontario, British Columbia, Alberta, and Quebec.
Europe was also confirmed as being an epicentre of the pandemic with Italy being considered the worst hit by the pandemic, followed by Spain which declared a state of emergency on March 13. According to the most recent WHO report, as of March 19, the number of confirmed cases worldwide exceeds 200,000 and the global death toll has surpassed 8,700 deaths.
To make matters worse, concerns for COVID-19 have also led to the cancellation of several public events and businesses around the world. This includes colleges and universities which have moved to close down their campuses and are moving classes online.
Cities around the world that are normally filled with people have had their streets practically emptied as people confine themselves in their homes. As the situation develops, it is important for people to remain calm, ensure they follow proper hygiene guidelines, and avoid public places and large gatherings, especially if they believe they are sick. The Canadian government is posting the latest guidelines and statistics online, updated daily.

As I made my way home today, I watched a woman on the subway platform reprimand another for wearing a surgical mask. “Shame on you,” she said. “There are people who need those. Shame on you.”
As the mask-wearing woman stumbled away from her aggressor, I couldn’t help but reflect on where we – the global “we” – are right now. Yes, surgical masks are in short supply, and our frontline healthcare workers are those in need. Wearing a mask as prevention against a virus that is not airborne simply serves as a flimsy barrier to keep your hand from reaching two of the three avenues of infection – the mouth and nose – and the general public can remain healthy without them.
But now is also not the time to bare our teeth. The present COVID-19 pandemic is a fight – that of microbe against the people. Shame on us, then, to turn it into people against the people.
As humanity, we are a collective. We have a responsibly to one another to remain a collective through support, through public health education, and imperatively, through access to resources for all.
On my same trip home, I heard a man tell his friend how in the grocery store a woman took all of the baby formula available and would not share with another costumer, even when begged.
We’ve fashioned our world into one with near unlimited resources, and near unlimited access to them. What we are now seeing is movement toward survival of those with means. And this reality rears its ugliest head when we act selfishly.
While we must practice social separation for the sake of our collective health, we must remember not to separate ourselves from the tenets that unite a prosperous humanity – those of promoting the common good, and the betterment of the world through help, especially when times are grim.
What happens when our crisis invades those of lesser means, of poorer healthcare? If we cannot act with a moral conscience now, then when? Faced with fear, this global pandemic has turned many of us inward. But now is the time where we must act ever more outward.
The only way to heal our population is with a collective push toward the good of one another, sibling and stranger alike. As more continue to fall ill world-wide, and as over-saturated healthcare systems are forced to prioritize the treatment of one over another, we must lend ourselves to collaborative support, so that the work of the front line is not in vain.
From simply staying home if we feel ill to washing our hands for the sake of us all, there is no act too small. But in not doing what we can, however little, we neglect our neighbour. And in using aggression, in refusing to share, we fail.
These are dire times, but we can all play a role in our healing. There is only one humanity. If we let one another fall, we all fall.

The 2019 novel coronavirus (2019n-CoV), like MERS and SARS, belongs to a family called coronaviruses that may be amenable to an approach to create a single vaccine effective against several infectious diseases.
Historically, vaccines have been developed by isolating, inactivating, and injecting viruses, bacteria or pieces thereof into the body to stimulate an immune response.
Recently, a more rational design approach has enabled the design of new candidate vaccines with high precision. It’s a potential game changer in vaccine development.
A group of researchers in the United States is using synthetic biology tools to develop a universal coronavirus vaccine. Using these tools, scientists redesign and construct artificial organisms to develop new abilities. They manipulate strands of DNA, insert them into an organism's genome, and create a new artificial DNA molecule designed for specific purposes.
Before they begin working with DNA, scientists at the University of Washington's Institute for Protein Design use a computer program to develop new vaccines against several viruses, including coronavirus. This technology allows them to design new vaccine candidates from scratch, including coronavirus antigens. These antigens are recognized by the human immune system, which then produces antibodies to help the body fight off the invader. When used in a vaccine, these antigens stimulate the body to create immunity to the disease.
Coronaviruses (CoV) are a large group of viruses that can infect humans and cause respiratory illness with a wide range of symptoms, ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). The 2019 novel coronavirus (2019n-CoV) causes an infectious disease called COVID-19.
This highly contagious disease has been declared a global pandemic disease by the World Health Organization (WHO). Although COVID-19 has a low mortality rate, meaning that most cases are mild, it spreads easily, so the minority of cases that are severe can still easily overwhelm health care systems.
To add perspective, the MERS virus has the highest mortality rate. One of three people infected die, typically because of a respiratory illness. However, it has a low transmission rate and since 2012, there have been about 2,500 cases worldwide. It is a lethal virus but doesn’t ostensibly spread to person-to-person. On the other hand, SARS virus is less deadly than MERS with a mortality rate of around 10 per cent, but much more contagious than MERS. Back in 2003, there were about 8,000 cases of SARS and about 800 deaths worldwide.
One of the worst pandemics in recent history was the 1918 Spanish flu, which killed about two to three per cent of its victims, or at least 50 million people worldwide. COVID-19 mortality has been estimated to be around 1.6 per cent. This disease has many similarities with influenza, since both are contagious diseases with low mortality rates. However, mortality for COVID-19 appears higher than the 2009 H1N1 pandemic that killed around a tenth of a per cent of affected people worldwide.
One hundred years after the Spanish flu, the world is a much more populous and different place. We are much more prepared for infectious diseases, but we are able to connect to each other around the world within hours via air travel making disease transmission easy and control of these diseases globally challenging.
The University of Washington researchers believe the new approach combining computational modeling and synthetic biology will help develop effective vaccines against all three coronaviruses, including SARS-CoV, MERS-CoV, and 2019n-CoV.
Using this strategy, scientists attached coronavirus-specific antigens to a spherical protein nanoparticle that looks like a virus to the body’s immune system, and as such stimulates antibody responses. These nanoparticles are now being tested in mice to evaluate immune responses in vivo.
The main advantages of having a nanoparticle as the core of a vaccine is that it can be used to boost immune responses and can be designed to include antigens from several viruses. This makes one vaccine capable of fighting multiple infectious diseases. It also makes the vaccine tolerant of heat, reducing the need for refrigeration - a great feature for vaccines that are used in tropical resource-poor countries.
Synthetic biology may offer a universal coronavirus vaccine that can be quickly modified to combat future mutated strains, but such vaccines remain in the preliminary phases and more traditional vaccines won't be available for months.
In the meantime, it will be up to us to keep washing our hands, avoiding crowded places, and doing what we can to control COVID-19. More info about the virus and what we can do to protect ourselves can be found here: https://www.who.int/emergencies/diseases/novel-coronavirus-2019

The family radiation cookers. This one is a Beaumark purchased in 1985 and uses microwave radiation. The traditional one in the reflection uses infrared radiation.
Recently, at a meeting in another city, the conversation turned to the example of a new home owner who refused to have a standard appliance installed for fear that it would expose the family to a greater risk of cancer.
Seriously? This one is still out there?
More than 50 years ago, in 1967, Amana Corporation introduced the Radarange, and with it, a whole new way of cooking food. Within a few decades, Amana and other companies had made the microwave oven standard equipment in nearly every kitchen in the developed world.
At the same time, there was unease about the new technology, in no small part because of a single word used to describe it: radiation.
My mother remembers newspaper advice columns at the time fielding questions from concerned homemakers about the new devices. They were reassured of their safety, but the unease persists to this day.
What would have happened, I wonder, if instead of “microwave radiation,” they had called it “microwave light?” Both are equally accurate.
Microwave light has wavelengths shorter than radio but longer than infrared. The heat you feel of one of those overhead heaters in a garage is infrared light. Another way to think of wavelengths is colour: the wavelengths of red light are longer than violet, for example.
Microwaves are pretty useful. Some wavelengths resonate with water molecules. That means if you shine microwave light on a water-containing substance, the water molecules start to move faster, or get hot. This is how a microwave oven works.
Microwaves are also used extensively in telecommunications - your cell phone uses them, for instance (typically between 900 Mhz and 1,800 Mhz). Microwaves are used because they can carry much higher information density than radio waves. So, when you’re using your cell phone, you’re using a microwave transceiver RIGHT BESIDE YOUR BRAIN (insert terrified scream here, and yes, I’m being sarcastic).
Popular phrases such as “nuke some dinner” don’t help. People are afraid of radiation, or at least what they think it radiation is. Light does radiate, even if you can’t see it (as I mentioned with the infrared heater). Incidentally, any incandescent bulb actually gives off much more infrared than visible light, which is why you can use them as a heat source.
Also, unless you’ve been very careful or very lucky, we pigment-challenged types have almost certainly had one or more radiation burns in our lives. This is because the shorter the wavelength of the light, the more energy it carries.
Light starts to get dangerous to us once you get into the ultraviolet range, something our sun is quite good at producing. So public health folks urge us to be careful, wear clothing, put on sunscreen to protect from radiation burns that can increase our risk of skin cancer. But we don’t often think of these as radiation burns; we just lament that we were careless and got a sunburn.
Words carry both meaning and emotion. “Light” and “radiation” can often be used interchangeably, but they carry much different emotional baggage. “Natural” and “synthetic” can be used to describe the same product, but how do these words make you feel? How about “organic” or “industrial?” “Corporate” vs “co-op?”
So, when crafting and consuming messages for ourselves and our clients, let us choose our words carefully – not only for meaning but for emotion.

Part 1: How the Manitoba government’s return to a deregulated hog industry could actually contribute to a world health emergency.
The Pallister government has just passed its “Red Tape Reduction and Government Efficiency Act.” The bill makes it easier (and cheaper) for pig producers to build new factory barns, expand existing ones, store and dispose of the waste and to even spend less on fire protection.
According to the industry group, “Manitoba Pork,” as many as 100 new factory barns may now be built over the next ten years.
What the Bill will not do is stop the dangerous overuse of antibiotics in animal agriculture. Livestock owners around the world (including Manitoba’s hog producers) have long been giving these medicines to their animals, whether to treat the sick, prevent the healthy from getting sick, or simply to fatten them up for market.
This is all perfectly legal here and in many other countries.
While it's true that antibiotics are sometimes used and abused in human medications too, the Public Health Agency of Canada (PHAC) estimates “80% of all antibiotic use in Canada occurs in the raising of animals for food.”
And, about three out of every four doses given this way, are identical to the drugs you and I need to fend off deadly infections.
The PHAC goes on, “There is increasing evidence that the use of antimicrobial agents in livestock production is an important contributing factor to the emergence of antimicrobial resistance (AMR) in humans.” AMRs are sometimes called “superbugs” which, because of this inappropriate use, have developed a resistance to treatment by most or all of the medicines available today.
So scenarios where doctors have to advise their patients that “There’s nothing more I can do for you," are becoming alarmingly more frequent.
Three days before the Manitoba bill was approved, the World Health Organization sounded its most urgent alarm yet over the administering of antibiotics to food animals. The WHO says things must change, if we are to preserve the effectiveness of these life-saving medications.The UN agency advised farmers and the food industry everywhere, to simply stop giving animals such medications altogether, whether to promote growth or prevent disease. Healthy animals should only be treated if disease is diagnosed elsewhere in the same herd. And, even while treating animals already sick, only medications not considered critical for the treatment of human infections, should be used.

But data from the Organization for Economic Cooperation and Development are even more alarming. Representing 35 developed countries, it notes that AMR is “highly prevalent” in its member countries (including Canada). It estimates the yearly loss of life, worldwide, probably runs into the tens of thousands, already. But current rates of resistance are increasing to the point where ten million people a year could be dying in this way by 2050! This, the OECD notes, would "move the needle" on the human cost of AMRs, from “substantial” to “enormous.” While the bulk of the deaths would be in Africa and Asia (see OECD table), there could still be 700 thousand in North America by that time. (No breakdown is given for Canada.)
Why, you ask, would an economic organization get involved in a health issue? Because, it expects future increases in health costs to also be enormous; almost $3 trillion by 2050, for OECD countries alone! That's because AMR patients are sick longer, need more (and costly) treatments, more tests and are three times more likely to die.
With new barns and more hogs now on Manitoba’s horizon, only pro-industry spin-doctors would dare to argue that this won’t mean more antibiotics, as well. (The OECD expects such usage to increase by a staggering two thirds by 2030.)
I have e-mailed both Premier Pallister and “Manitoba Pork” to ask them about these concerns. Neither has responded, so far.
So, if the world pays as little heed to this prevailing medical wisdom as the Pallister government and the industry seem to be doing, for this Manitoban, "optimistic" just got harder to be.

I’m an eco-journalist living in Shoal Lake, Manitoba. I’m a member of the SWCC and the American Association for the Advancement of Science. I’m authorized to receive embargoed material through the Science Media Centre of Canada, the Royal Society and the World Health Organization. This allows me to “get a jump” on important stories by fleshing them out with fact-checks and interviews, in advance. Often, this arms me with a “hot-off-the-press” story that’s ready to go, the moment the embargo is lifted.
I’m prepared to supply interested publications with important stories in the field of the Earth Sciences – stories often stranger than fiction! I publish www.PlanetInPeril.ca (PinP), “Where science gets respect.”
