Life and death of an 'altruistic' bacterium
Life and death of an ’altruistic’ bacterium
A new study led by Yves Brun shows how some bacteria living in a biofilm sacrifice themselves to ensure the survival of the community. CONTENU - Biofilms, complex communities of bacteria, abound around us: on the surface of cheese where they give off flavors and aromas, in streams where they form the slimy substance on rocks, on our teeth where they form plaque.

New branch on tree of life includes ’lions of the microbial world’
Science, Health & Technology Alex Walls There's a new branch on the tree of life and it's made up of predators that nibble their prey to death. These microbial predators fall into two groups, one of which researchers have dubbed "nibblerids” because they, well, nibble chunks off their prey using tooth-like structures.

What AI-generated COVID news tells us that journalists don't
What AI-generated COVID news tells us that journalists don’t
AI can help identify biases in news reporting that we wouldn't otherwise see. Researchers from McGill University got a computer program to generate news coverage of COVID-19 using headlines from CBC articles as prompts. They then compared the simulated news coverage to the actual reporting at the time and found that CBC coverage was less focused on the medical emergency and more positively focused on personalities and geo-politics.

A new understanding of pain disparities among racial groups in U.S. 
A new understanding of pain disparities among racial groups in U.S. 
A new study co-authored by Western researcher Anna Zajacova shows that racial and ethnic disparities in pain prevalence in the U.S. are far larger than previously realized, with multiracial and Indigenous (Native American/Alaska Native) adults reporting the highest levels of pain. She says this finding is significant because pain can be used as a barometer of mental and physical health of a population.  "We aren't talking about one particular type of pain, we are looking at pain overall," said Zajacova, sociology professor at Western.

High rates of iron deficiency in women during late-stage pregnancy
Science, Health & Technology Collins Maina Pregnant women may need to take more supplemental iron than current Health Canada guidelines recommend, after two UBC researchers found high rates of iron deficiency in a recent study. The research investigated iron deficiency prevalence among 60 pregnant women in Metro Vancouver and found that over 80 per cent of them were likely iron-deficient in late pregnancy despite taking daily prenatal supplements that provided 100 per cent of the daily iron recommendation in pregnancy.

Greenspaces should support mental health among young adults
Greenspaces should support mental health among young adults
Even though many global cities incorporate greenspaces such as pocket parks and community gardens into their urban planning efforts, new UBC research shows those plans often fail to include the needs of youth and young adults between the ages of 15 and 24. As a result, this age demographic can miss out on the known social, physical and mental health benefits of these nature-based solutions.

Study suggests honey reduces cardiometabolic risks
Researchers at the University of Toronto have found that honey improves key measures of cardiometabolic health, including blood sugar and cholesterol levels - especially if the honey is raw and from a single floral source. The researchers conducted a systematic review and meta-analysis of clinical trials on honey and found that it lowered fasting blood glucose, total and LDL, or "bad," cholesterol, triglycerides and a marker of fatty liver disease.

Researchers identify SARS-CoV-2 variant in white-tailed deer, evidence of deer-to-human transmission
In the summer of 2020, months after the World Health Organization declared COVID-19 a global pandemic,  Samira Mubareka  and her colleagues began testing wildlife in Ontario and Quebec for the new coronavirus SARS-CoV-2. "Pretty early in the pandemic, we knew that there was spillover from humans to animals," said Mubareka, who is a clinician scientist at Sunnybrook Research Institute and an associate professor in the department of laboratory medicine and pathobiology in the Temerty Faculty of Medicine at the University of Toronto.
