Western study finds co-infection with 'superbug' bacteria increases SARS-CoV-2 replication The study identifies a common protein from the Staphylococcus aureus bacteria boosts SARS-CoV-2 replication up to 15 times By Prabhjot Sohal , March 20, 2023 By Prabhjot Sohal , March 20, 2023 Global data shows nearly 10 per cent of severe COVID-19 cases involve a secondary bacterial co-infection – with Staphylococcus aureus, also known as Staph A.
"If you pick a spot in, say, a rainforest, and count the number of different species of lizards within 15 metres and you come up with a number," says Luke Mahler , "What determines that number?" Mahler is an assistant professor in the University of Toronto's department of ecology and evolutionary biology in the Faculty of Arts & Science.
Financial landlords own four times more rental units than previously thought
Financial firms have moved in on Montreal's rental housing market New research indicates that a small percentage of financial landlords, like private equity firms and institutional investors, own four times more of Montreal's rental housing stock than was previously estimated. Neighbourhoods with more financial landlords are also experiencing higher housing stress levels.

A collaborative study between researchers at Simon Fraser University and Fisheries and Oceans Canada (DFO) has found that high logging intensity in the Interior watersheds of British Columbia is associated with warmer stream temperatures in salmon-bearing streams, potentially contributing to increased heat stress in salmon.
Employees tend to avoid taking breaks despite high levels of stress
Employees may feel pressure to continue working to get everything done on time Heavy workloads make employees feel a greater need for a break, but new research finds they may actually discourage employees from taking breaks at work despite causing high levels of stress, fatigue, and poor performance.

Despite the power of deep learning, computers have yet to master human calculations when it comes to visual recognition By Jeff Renaud , March 16, 2023 By Jeff Renaud , March 16, 2023 When a human spots a familiar face or an oncoming vehicle, it takes the brain a mere 100 milliseconds (about one-tenth of a second) to identify it and more importantly, place it in the right context so it can be understood, and the individual can react accordingly.
Colorectal cancer and E. coli: new insights
UdeM researchers have found that a lot of healthy people have a gut bacteria implicated in colorectal cancer, and that a popular supplement for promoting digestive health may have the opposite effect. In Quebec, colorectal cancer is the second leading cause of cancer deaths in men and the third in women.

Fresh produce contaminated with toxic BPA-like chemicals found in food labels
Steps were taken in Canada to reduce the use of Bisphenol A (BPA), a toxic chemical linked to prostate and breast cancer, commonly found in plastics, the lining of food cans, water bottles, and paper receipts. But in many cases, it has been replaced with similar hormone disrupting chemicals, like Bisphenol S (BPS).

All it takes is some physical activity every day and less time spent in front of a screen, Canadian researchers find.
A team of University of Toronto researchers, led by Professor Yu Zou in the Faculty of Applied Science & Engineering, is working to advance the field of metal additive manufacturing at the university's first metal 3D printing laboratory.
Depression is widely reported to be more common in women than in men, with women twice as likely to receive a diagnosis than men. A new sex-specific study from McGill University has found that there are differences between male and female genes and how they relate to depression. In a study of more than 270,000 individuals, the researchers found that sex-specific prediction methods were more accurate in forecasting an individual's genetic risk of developing depression than prediction methods that did not specify sex.
Researchers say data science may eventually help predict a film's success From the sepia tones of a Coen brothers film set in the Dust Bowl to a child's red coat in Schindler's List, filmmakers have long known the power of colour in movies. Now, computer scientists have analyzed 60 years of films to paint a picture of the past six decades in film.
Alcohol during pregnancy: drinking too much in the first week is risky
But consuming foods rich in nutrients could counteract some of the negative effects, according to a new Canadian study. CONTENU Serge McGraw, chercheur en épigénétique et spécialiste en biologie de la reproduction au CHU Sainte-Justine Credit: CHU Sainte-Justine Excessive alcohol consumption in the first week of pregnancy poses risks to the unborn child - but having a healthy diet rich in nutrients such as folic acid, vitamin B12, choline and betaine could reduce some of its effects, a new Canadian study reveals.

Decade-long research shows home feeders don't alter chickadee reproduction or behaviour By Megan Stacey , By Megan Stacey , March 09, 2023 Never throw bread to the neighbourhood ducks. Keep dogs and cats away from chocolate. There is a long list of rules for feeding animals. But when it comes to backyard songbirds, there is research to justify the bird feeder.
COVID-19 has taken a relatively limited toll on the mental health of most people around the globe, according to a paper published today in the by a McGill University-led research team involving collaborators from McMaster University, the University of Toronto, and other institutions. The team reviewed data from 137 studies in various languages involving 134 cohorts of people from around the world.
Many parents report health risks prior to pregnancy: Study
We know that a person's health during pregnancy impacts their child's developmental trajectories, but what about parental health before conception? A new study led by Cindy-Lee Dennis , a senior scientist at the Lunenfeld-Tanenbaum Research Institute at Sinai Healthand a professor in the University of Toronto's Lawrence S. Bloomberg Faculty of Nursing, found that a significant number of Canadian women have poor preconception health or interconception health, which refers to the period between two pregnancies.

Pandemic anniversary highlights need for expanded bereavement support services
The COVID-19 pandemic, which killed millions across the world, had a dire impact on the ability of their loved ones to grieve. A study by Simon Fraser researchers published in the journal Illness, Crisis & Loss , calls for expanding pandemic grief support programs and increasing public awareness of the existing supports available to help lessen the emotional toll.

Connecting Canada and Europe through quantum satellite communication
New HyperSpace collaboration envisions secure quantum connections across the Atlantic Ocean By Elizabeth Kleisath Institute for Quantum Computing Dr. Thomas Jennewein, a faculty member at the Institute for Quantum Computing (IQC) and the University of Waterloo's Department of Physics and Astronomy, has his sights set high and wide - specifically on a quantum satellite orbiting high above the Earth to connect Canada and Europe via a secure quantum communication link.

More evidence that sugary drinks cause weight gain: Study
A review of dozens of studies from the last decade recently found that sugar-sweetened beverages promote weight gain in children and adults. The review, led by researchers at the University of Toronto and Harvard University, is the largest and most thorough analysis to date of research on sweetened drinks, and overweight and obesity - both of which heighten risks for diabetes, heart disease, some cancers and other diseases.

Simon Fraser scientists say their research on the latest fossil find near Princeton, B.C. is raising questions about how the dispersal of animals and plants occurred across the Northern Hemisphere some 50 million years ago, including whether brief intervals of global warming were at play.
