New method for tracing viral DNA through evolution uncovers hidden sequences with gene-regulating potential, prompting a closer look at the human genome 25 years after it was first mapped Fragments of ancient viral DNA once dismissed as "junk" may play a role in controlling our genes, according to a new international study.

Farmers in Tanzania were more likely to adopt climate-friendly techniques when given the chance to exchange ideas with their peers  Farmers who exchanged text messages with peers were significantly more likely to adopt sustainable agricultural practices, highlighting the power of peer learning in digital formats, a new study co-authored by McGill University Professor Aurélie Harou found.

Researchers use machine learning to bridge the gap between what patients feel and what medical tests can measure, opening the door to better diagnosis and treatment A new study by McGill researchers shows that chronic pain, often invisible to medical tests, can be better assessed when doctors take a holistic approach.

Innovative strategy has the potential to revolutionize the treatment of breast cancer, particularly for patients who have developed resistance to targeted therapies A ground-breaking study conducted by researchers from McGill University, the Lady Davis Institute for Medical Research (LDI) at the Jewish General Hospital, Princess Margaret Cancer Centre and MIT has identified a novel approach to combat aggressive breast cancers by retraining neutrophils, the body's first responders, to directly kill tumour cells.

A team of McGill researchers, working with colleagues in the United States and South Korea, has developed a new way to make high-performance lithium-ion battery materials that could help phase out expensive and/or difficult-to-source metals like nickel and cobalt. The team's breakthrough lies in creating a better method of producing "disordered rock-salt" (DRX) cathode particles, an alternative battery material.

Discovery could help explain why some people are more vulnerable to lung damage during severe inflammation Trained immunity - a process being explored in vaccine and therapy development to boost immune defences - appears be counterproductive in certain contexts, researchers at McGill University and the Research Institute of the McGill University Health Centre (The Institute) have found.

From ill-fitting instruments to assumptions about competence, surgical culture sidelines women, first Canadian study of its kind suggests Women now make up over half of medical students in Canada, but only one-third of practising surgeons. A new study suggests part of the gap stems from gender norms embedded in workplace culture.

Study adds to growing evidence that social and psychological factors uniquely affect women's heart health, offering new insights into why heart disease presents and progresses differently in women. Women who see themselves as having lower social status are more likely than other people to show early signs of heart stress linked to future disease risk, according to a new study led by researchers at McGill and Concordia universities.

A new preclinical study unveils a more powerful and effective immunotherapy for bladder cancer and other solid tumours. BCG therapy-the gold standard treatment for non-muscle invasive bladder cancer (NMIBC), where the cancer has not penetrated the muscle layer-is one of the earliest forms of cancer immunotherapy.

A first-of-its-kind clinical trial found that ketamine's benefits for treating severe depression can be improved when combined with psychotherapy and supportive treatment environments. Led by researchers at McGill University, the study suggests this approach can yield valuable therapeutic experiences that lead to longer-lasting relief than standard treatment.

McGill-led study shows that being 'on the same page' reduces uncertainty in tumultuous times and increases satisfaction with life and work Fostering shared understanding between romantic partners may be a powerful way for people to navigate uncertainty and build a more meaningful life, a study by McGill researchers suggests.

McGill-led study shows that environmental history and microbiome stability shape how corals withstand extreme heat, offering insights for reef conservation in a warming world A new study led by researchers at McGill University and the Smithsonian Tropical Research Institute (STRI) in Panama reveals why some corals resist bleaching while others don't: the answer lies in a complex partnership between corals and their microbial allies, shaped by the history of the waters they inhabit.

Breakthrough could help oat farmers boost yields, reducing reliance on chemicals used to speed up harvests For the first time, scientists have successfully edited oat DNA, a breakthrough that could accelerate the development of oats with more fibre, higher yields, and greater resilience to climate change.

Consensus on how mindset and surroundings shape therapy outcomes is an important step toward regulatory approval for use of drugs like MDMA and psilocybin in treatment of debilitating mental health conditions As psychedelics gain traction as potential treatments for mental health disorders, an international study led by researchers at McGill University, Imperial College London, and the University of Exeter stands to improve the rigour and reliability of clinical research.

McGill researchers' analysis of online forum conversations finds that some incels offer an ideological rationale for not working or studying, one reinforced by peer pressure The critically acclaimed Netflix drama Adolescence has put a spotlight on the culture and ideas of incels (involuntary celibates), an online subculture of people (mostly male and heterosexual), who define themselves as unable to find a romantic or sexual partner, largely due to their perceived unattractiveness.

Study delved into the social factors that influence whether older adults are able to remain in their homes and communities  While health status is an important factor in whether a person is able to grow old in their home and community (age in place), researchers at McGill University have shed new light on the social factors that can also have an impact, both directly and through their impact on health over a lifetime.

Researchers estimated about 8,500 tonnes of antibiotics end up in river systems each year after passing through the human body and wastewater systems Millions of kilometres of rivers around the world are carrying antibiotic pollution at levels high enough to promote drug resistance and harm aquatic life, a McGill University-led study warns.

McGill researchers develop a method that could revolutionize biomedical and environmental applications  Researchers at McGill University, in collaboration with Polytechnique Montréal, pioneered a new way to create hydrogels using ultrasound, eliminating the need for toxic chemical initiators.

Study suggests that combining hockey scouts' judgements with objective testing could help identify the players with the best 'game sense' In a study that is the first of its kind, a research team led by a McGill professor has developed a more objective way to identify ice hockey players' game intelligence, or "hockey IQ.

McGill researchers develop practical new tool for detecting nanoplastics and microplastics in the environment A team of McGill researchers has developed a cost-effective, high-throughput technology for detecting nanoplastics and microplastics in the environment. These particles are pervasive, posing health and environmental risks, yet detecting them at the nanoscale has been difficult.
