What links cannabis use and psychosis? Researchers point to the brain’s dopamine system
'Our findings could help doctors and mental health professionals better educate patients about the potential risks of frequent cannabis use' A McGill University-led study found that people with cannabis use disorder (CUD) had elevated dopamine levels in a brain region associated with psychosis. "This could help explain why cannabis use increases the risk of hallucinations and delusions, key symptoms of schizophrenia and other psychotic disorders," said first author Jessica Ahrens, a PhD candidate in McGill's Integrated Program in Neuroscience.

You can heal more wounds with honey
UdeM pharmacy professor Simon Matoori has reviewed studies on the therapeutic properties of honey in the treatment of both acute and chronic wounds. It's a remedy that dates back to Pharaohs-one that doctors still use today to treat certain acute and chronic wounds, although in a different form than ancient Egyptian physicians knew.

Accelerating drug development with AI
Accelerating drug development with AI
Developing new drugs to treat illnesses has typically been a slow and expensive process. However, a team of researchers at the University of Waterloo uses machine learning to speed up the development time. The Waterloo research team has created "Imagand," a generative artificial intelligence model that assesses existing information about potential drugs and then suggests their potential properties.

McGill discovery sheds new light on autism, intellectual disabilities
A new study by McGill researchers yields insights into how the disruption of calcium transport in the brain is linked to autism and intellectual disability. The findings, published in the journal Nature, not only upend a long-held belief among neuroscientists, but could pave the way for treatments. The researchers discovered that tiny protein structures on brain cells, known as AMPA receptors, can transport calcium.

Potential for Omega-3 to counteract THC effects on fetal development
Potential for Omega-3 to counteract THC effects on fetal development
Previous studies show exposure to Tetrahydrocannabinol (THC) - the main psychoactive component in cannabis - while in utero can lead to lower birth weight and potential heart complications in newborn animal offspring. For the first time, researchers from Western's Schulich School of Medicine & Dentistry have found a potential way to prevent those effects.

Hidden forces shape plants from the inside out
UdeM scientists use a combination of experimental data and modelling to reveal how physical forces help plants to generate their complex 3D shapes. Sylvia Silveira, Daniel Kierzkowski, Anne-Lise Routier-Kierzkowska and Loann Collet Credit: Amélie Bauer Plants don't just grow, they build. From towering trees to delicate flowers, complex plant shapes are sculpted with remarkable precision.

Investing in your work: a fine balance between dedication and burnout
Investing in your work: a fine balance between dedication and burnout
According to a study by Marie-Colombe Afota, how people see themselves plays an important role in their intense-and sometimes toxic-approach to work. How do workaholics' self-image influence their degree of dedication to their job? And how does that impact their mental health? To find out, Marie-Colombe Afota, a professor in Université de Montréal's School of Industrial Relations, teamed up with colleagues in Montreal and France to study 544 graduates of a French business school over an eight-month period.

COVID-19 boosters help avoid breakthrough infections in immunocompromised people
Researchers focused on those with rheumatoid arthritis, lupus, inflammatory bowel disease, multiple sclerosis and other immune-mediated inflammatory diseases New research findings provide solid evidence that annual COVID-19 vaccine booster doses continue to be advisable for certain immunocompromised people, researchers at McGill University say.

Humpback whales’ use of memory to time their migration could prove less effective amid climate change
Researchers express concern the animals' strategy may not be able to keep pace with rapidly changing conditions A new study led by McGill researchers indicates that humpback whales in the southeastern Pacific combine real-time environmental cues with their memories of conditions in their Antarctic feeding grounds to determine when to embark on their annual 10,000-kilometre journey.

AI analysis challenges autism diagnosis criteria
Researchers suggest behavioural traits are more telling than social communication and interaction factors, so diagnostic focus should be sharpened An analysis of digital health records using large language models (LLMs) is challenging a long-held belief about the clinical identifiers of autism. A new study led by researchers at The Neuro (Montreal Neurological Institute-Hospital) of McGill University and Mila Quebec AI Institute found that social communication factors may not be as important in identifying the condition as previously believed.

Unconventional quantum computer can help unveil fundamental mysteries of the universe
For the first time, researchers at the University of Waterloo's Institute for Quantum Computing (IQC) and the University of Innsbruck in Austria have performed a quantum simulation of a two-dimensional particle physics theory on a qudit quantum computer, bringing us closer to understanding nature at its most fundamental level.

Evidence mounting that dark energy evolves over time
According to the Standard Model of Cosmology, the expansion of our universe is driven by the simplest possible version of dark energy: an unchanging 'cosmological constant' called lambda.  "It's the start of a new era," says Will Percival, professor and director of the Waterloo Centre for Astrophysics at the University of Waterloo, and associate faculty at Perimeter Institute for Theoretical Physics.

Demystifying a genetic disease of the heart muscle
A large-scale study in which UdeM cardiologist Rafik Tadros took part focuses on the origins of hypertrophic cardiomyopathy, or HCM. Affecting one in 500 people, hypertrophic cardiomyopathy is a condition in which the walls of the left ventricle, the heart's main pumping chamber, become abnormally thick.

Salmonids may be more vulnerable to interacting environmental stressors than previously thought, SFU study finds
The knock-on effects of cumulative threats to salmonids has Simon Fraser researchers pushing for more effective strategies to protect British Columbia's most important fish populations. Salmonids - which include salmon, trout, charr and grayling- are vital to communities and ecosystems such as those of the West Coast, yet little is known about how these species will respond as the stressors they face compound - an increasingly likely scenario under climate change.

Study of velvet worm slime could revolutionize sustainable material design
McGill researchers want to harness a natural process that enables slime's transformation from liquid to fibre and back again A new discovery about the slime ejected by velvet worms could revolutionize sustainable material design, according to a study by McGill researchers. Their findings outline how a naturally occurring protein structure, conserved across species from Australia, Singapore and Barbados over nearly 400 million years of evolution, enables the slime's transformation from liquid to fibre and back again.

Brain imaging technique discovered by researcher drives AI audiovisual analysis
When a person's hearing and vision are uncompromised and function at a relatively high level, the human brain is able to take in various sights and sounds from any environment and seamlessly allow said person to perceive what's happening around them. But how does it work? Spoiler alert: There's more than meets the eye.

Potential strategy to help patients living with HIV
A new study led by Western researchers is the first to identify a factor that could influence how fast the pocket where human immunodeficiency virus (HIV) hides dormant inside of cells shrinks when treated. HIV is difficult to cure, partly due to the virus' ability to create a "latent reservoir" - where it hides dormant inside of cells, safe from detection.
