Traditionally-recognized socially vulnerable groups in Canada bear a disproportionate burden of flood risks Socially vulnerable groups are at greater risk from climate-change-caused flooding because of systemic disadvantages, according to a new study. The study also reveals that neighbourhood-level racial or ethnic, economic, social, and demographic factors play a significant explanatory role in the distribution of flood risk across Canadian neighbourhoods.
What causes cell ’batteries’ to run down
Researchers at the University of Toronto have discovered how mitochondrial turnover - a critical cellular function - begins. Mitochondria are like the batteries of our bodies. They're vital sources of energy for cells and are necessary to regulate function in almost all cell types. And, like batteries, mitochondria need to be replaced as they run down over time. If these cell batteries aren't replaced efficiently, and don't turn over properly, cells experience stress and can die.

Speculation taxes rarely dissuades large-scale investors from purchasing property and leaving it vacant. As the Ontario housing market enters a potentially volatile phase, new research from the University of Waterloo shows how tax policy has proven ineffective in controlling prices. The report specifically looked at market behaviour of the nine largest Ontario population centres between 2011 and 2021 - a time of significant price increases across the province.
An increasingly globalized Arctic Indigenous population wants to be involved in decision-making about adapting to accelerated Arctic changes A national survey of close to 1000 adults in Greenland (where approximately 90% of the population is Indigenous) conducted by a McGill University-led research team has found that a surprisingly large majority - 3 out of 4 Greenlanders - support extracting and exporting sand left by the melting ice sheet.
A recent study by researchers at the University of Toronto has identified a chemical found in several consumer products that could be a potential cause of the rise of antibiotic resistance In Canada. The study, by Assistant Professor Hui Peng 's research group in the department of chemistry in the Faculty of Arts & Science, was able to show that triclosan - a chemical often included in household items like hand soaps, toothpastes, and cleaning products to fight off bacteria - is the predominant antibiotic in Ontario sewage sludge.
Working too hard? New SFU research highlights importance of taking breaks
Work breaks should be seen as recovery opportunities that foster employee well-being and do not detract from performance, according to a Simon Fraser University researcher. Zhanna Lyubykh, assistant professor, Management and Organization Studies at the Beedie School of Business led a systematic review of 83 studies focused on the role of work breaks in fostering well-being and performance.

’Happy spouse, happy house?’ Study finds men and women equally strong predictors of relationship satisfaction
Researchers have found that men and women are both equally strong predictors of future relationship satisfaction in mixed-gender relationships - suggesting the phrase "Happy spouse, happy house" is not only a more inclusive maxim than the old saw about wives and lives, but far more accurate. "People experience ups and downs in their romantic relationships," says Emily Impett , a professor in the department of psychology at University of Toronto Mississauga.

Science, Health & Technology Brett Goldhawk Researchers at the University of British Columbia have discovered a key vulnerability across all major variants of the SARS-CoV-2 virus, including the recently emerged BA.1 and BA. Omicron subvariants. The weakness can be targeted by neutralizing antibodies, potentially paving the way for treatments that would be universally effective across variants.
A research team supervised by Anne Gallagher is investigating whether babies can learn language in the womb. Does exposing babies to different languages during pregnancy promote the acquisition of language skills before birth? This is what a research team at the LION laboratory is trying to determine.
University of Toronto report shows food insecurity persists across Canada, varies by province
The latest national data from researchers at the University of Toronto show that food insecurity in Canada has remained largely unchanged over the last three years, with stark differences among the provinces. The report, "Household Food Insecurity in Canada 2021 ," shows that 15.9 per cent of households across 10 provinces experienced some degree of food insecurity in the year before fall 2021, with little change since 2019.

Scientists have discerned a sharp ring of light created by photons whipping around the back of a supermassive black hole in a vivid confirmation of theoretical prediction When scientists unveiled humanity's historic first image of a black hole in 2019 - depicting a dark core encircled by a fiery aura of material falling toward it - they believed even richer imagery and insights were waiting to be teased out of the data.
An international team of researchers has discovered groundwater that is more than a billion years old deep below Earth's surface - only the second time such a discovery has been made. The water, which is 1.2 billion years old, was recovered from a goldand uranium-producing mine in Moab Khotsong, South Africa, confirming that groundwater of such a vintage is more abundant than previously thought.
A new chemical compound under development at Simon Fraser University could give beekeepers an edge in the fight against varroa mites, a deadly parasite that affects honeybees. At her apiary in South Surrey, SFU Chemistry professor Erika Plettner is in the third year of field trials of a new treatment for managing these pests, which have become a serious problem for beekeepers around the world.
COVID-19 vaccine and young children - expert answers for skeptical parents
Thanks to a recent decision by Health Canada, children in British Columbia over the age of six months are now eligible for COVID-19 vaccinations. And a recent study by UBC researchers reveals some surprising attitudes about child vaccination from parents who remain unvaccinated. Dr. Ran Goldman, professor of pediatrics at UBC, answers some questions for parents looking for more information before vaccinating their children.

Employees are motivated by rewards that are perceived as distinct from salary Tangible rewards motivate employees when they're easy to use, pleasurable, unexpected, and distinct from salary, a new study found. A recent survey of firms in the United States revealed that 84 per cent spent more than $90 billion annually on tangible employee rewards, such as gift cards, recreation trips and merchandise in hopes of increasing productivity.
Measuring the social impact of disruptive weather, plus other stories
New research stories from McGill University. Using artificial intelligence to study the social impact of disruptive weather events Does a -disruptive weather event- imply extreme weather? Not necessarily, say two McGill researchers. Instead of focusing on social impacts, weather research tends to focus on meteorology.

Summer is almost over, but that doesn't mean mosquitoes aren't still searching for their next meal-and you might be next. A new study co-authored by UBC's Dr. Ben Matthews suggests humans may just be the most sought-after delicacy for the pesky insects. A common type of mosquito, the globally invasive Aedes aegypti, literally sniffs out humans, driving them to bite us even over other animals.
Researchers have discovered that they can control the stickiness of adhesive bandages using ultrasound waves and bubbles. This breakthrough could lead to new advances in medical adhesives, especially in cases where adhesives are difficult to apply such as on wet skin. -Bandages, glues, and stickers are common bioadhesives that are used at home or in clinics.
Stormwater management ponds may not hold the solution for depleting wetlands
Researchers recommend that protections be strengthened for wetlands of all sizes Relying on stormwater management (SWM) ponds to restore the depleting wetlands is not sustainable and lacks the critical ecosystem services vital for biodiversity, a new study found. With the continued losses of wetlands projected in the near future and emphasis on the underestimation of provincial wetland loss, the study captures the contributions of SWM ponds in a changing network of water bodies and the effects of land use and land cover in this change.
