Researchers identify genes and markers associated with resistance to a commonly used hormone treatment Researchers at Laval University have discovered markers and genes associated with resistance to a hormone treatment commonly given to people with prostate cancer. These advances, reported in an article published by NAR Cancer , could lead to better use of this treatment and the development of new, more effective cancer treatments.
There's more to a strand of hair than meets the eye. This human tissue is a chronological record-keeper of the adversities endured by the human body and mind. A new study co-authored by researchers at Schulich School of Medicine & Dentistry's Drug Safety Lab analyzes the relationship between war exposure, current living conditions, hair cortisol concentrations (HCC) and post-traumatic stress disorder (PTSD) symptoms.

Experimental physicists at the University of Toronto are closer to understanding why some icicles form with ripples up and down their outsides, while others form with smooth, slick, even surfaces. By growing icicles from water samples with different contaminants like sodium chloride (salt), dextrose (sugar) and fluorescent dye, the researchers discovered that water impurities become entrapped within icicles as they form and subsequently create chevron patterns that contribute to a ripple effect around their circumferences.
Researchers test promising tech treatment for youth depression
New research shows promising results using neurotechnological approaches to treat depression in youth. The research, led by Simon Fraser University (SFU) professor Faranak Farzan, is published in the Journal of Affective Disorders Reports. Researchers investigated the clinical and neurophysiological effects of using brain stimulation followed by cognitive exercise for treating Major Depressive Disorder (MDD) in 26 youth (aged 16 - 24 years old).

New AI method for public health analysis shows trends in substance use among high schoolers
University of Waterloo researchers take a novel approach to public health analysis High school students who have a large weekly allowance, friends who smoke and low levels of physical activity are more likely to use multiple substances over time. Conversely, being older, being Black and eating breakfast daily were factors associated with a smaller chance of transitioning to multiple use.

Does evolution follow certain rules? Can these rules be predicted? Southeast Asia's tree shrews break multiple rules when it comes to body size variation - with an unexpected twist - according to researchers from McGill University, University of Cambridge, and Yale University. The findings shed new light on the effects of climate change on the evolution of body size in animals.
Waterloo researchers develop treatment scheduling method to target heterogeneous tumours Researchers at the University of Waterloo have identified a new method for scheduling radiation therapy that could be as much as 22 percent more effective at killing cancer cells than current standard radiation treatment regimens.
Poverty linked to Facebook and Instagram addiction in teens Adolescents from lower-income backgrounds are more likely to report addictive use of social media, according to an international team of researchers including McGill University Professor Frank Elgar. The findings show a link between economic inequality and problematic use of social network platforms and instant messaging applications.
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.
The James Webb Space Telescope reveals another first: a full menu of atoms, molecules, and even signs of active chemistry and clouds in the distant 'hot Saturn" known as WASP-39 b. CONTENU - Known for beaming stunning images back to Earth, the James Webb Space Telescope (JWST) just scored another first: a molecular and chemical portrait of a distant world's skies.
New quantum tool developed in groundbreaking experimental achievement
Scientists recreate properties of light in neutral fundamental particles called neutrons For the first time in experimental history, researchers at the Institute for Quantum Computing (IQC) have created a device that generates twisted neutrons with well-defined orbital angular momentum. Previously considered an impossibility, this groundbreaking scientific accomplishment provides a brand new avenue for researchers to study the development of next-generation quantum materials with applications ranging from quantum computing to identifying and solving new problems in fundamental physics.

Drylands are experiencing increasingly levels of degradation and desertification, changes that could put already vulnerable populations at greater risk. A research team, including Natasha MacBean , conducted an examination of dryland productivity and its important role in global carbon and water cycling, to understand the impact of climate change and human activity on future dryland ecosystem functioning.
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.

Tick-borne pathogens, known for causing illnesses such as Lyme disease, are on the rise in Central Canada - presenting new risks in areas where they were never previously detected. The findings from researchers at McGill University and the University of Ottawa demonstrate the need for more comprehensive testing and tracking to detect the spread and potential risk of tick-borne pathogens to human and wildlife populations throughout Canada.
Alumni Know: Why does giving feel good?
Social psychologist Sara Konrath (BA '02) shares the science behind giving and some unexpected benefits of generosity By Megan Vander Woude Office of Advancement Every November and December, we hear a lot about giving. No matter what you're celebrating this holiday season, you're sure to be inundated with messages of spending time with loved ones, giving thoughtful gifts and giving back to others.

The Winchcombe meteorite, a rare carbonaceous meteorite which crashed onto a driveway in Gloucestershire in 2021, has been found to contain extra-terrestrial water and organic compounds that reveal insights into the origin of Earth's oceans. A new study, published today by Science Advances , led by experts from the Natural History Museum and the University of Glasgow reports the orbital history and first laboratory analyses of the Winchcombe meteorite, which was recovered only hours after its spectacular fireball lit up the skies over the U.K. in February 2021.
COVID-19 is the ninth pandemic, or large-scale epidemic, the world has experienced in the past century - and it won't be the last. To help the public and policymakers better navigate the next global outbreak, the University of Toronto has created the Institute for Pandemics (IFP) based at the Dalla Lana School of Public Health.
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.
New tool developed to monitor health of marine ecosystems and extinction risk of species
Scientists from Simon Fraser University are part of an international team of researchers that has developed a new science-based indicator to assess the state of health of the oceans-and the possible risk of extinction of their species. Recent biodiversity studies show an unprecedented loss of species, ecosystems and genetic diversity on land, but the extent to which these patterns are widespread in the oceans is not yet known.
