A small but significant proportion of morbidly obese people are missing a section of their DNA, according to research published today in Nature.
People with Parkinson’s disease suffer social difficulties simply because of the way they talk, a McGill University researcher has discovered. Marc Pell, at McGill’s School of Communication Sciences and Disorders, has learned that many people develop negative impressions about individuals with Parkinson’s disease, based solely on how they communicate.
Dr. Phil Gold made Canadian medical history in 1965—and now it’s official. Forty-five years after he and his colleague Dr. Samuel Freedman discovered the carcinoembryonic antigen (CEA)—which, as the first clinically useful human tumour marker, revolutionized the diagnosis and management of cancer—Gold is being inducted into the Canadian Medical Hall of Fame.
The accelerated world of medical research promises new diagnostic tools and treatments for Parkinson’s disease, multiple sclerosis, Alzheimer’s disease, and even cancer. These advances, however, raise a daunting array of ethical issues. Enter Bartha Maria Knoppers, the recently appointed director of McGill’s new Centre of Genomics and Policy.
Brenda Milner needs a bigger mantelpiece. On November 20, 2009, in a ceremony held in Berne, Switzerland, the legendary Montreal Neurological Institute researcher received the International Balzan Prize, yet another entry on her long list of prestigious accolades.
Scientists long tried to figure out why some spots on Earth had more radioactive air than others. It wasn’t until 1912, when Victor Hess took an electrometer skyward in a balloon, that it became clear the extra radiation was coming, not from inside the Earth, but from above it. Way above it. But where exactly did these “cosmic rays,” as physicist Robert Millikan dubbed them, come from?
Bertrand Russell once described drunkenness as “temporary suicide,” a phrase that might turn out to be more literally true than the great philosopher knew. Heavy drinkers of beer and spirits face a much higher risk of developing cancer than the population at large, according to a recent study published in the journal Cancer Detection and Prevention by researchers from McGill and elsewhere.
Scientists have identified a double agent in the eye that, once triggered, can morph from neuron protector to neuron killer. The discovery has significant health implications since the neurons killed through this process results in vision loss and blindness.
Malaria causes more than two million deaths each year, but an expert multinational team battling the global spread of drug-resistant parasites has made a breakthrough in the search for better treatment.
Studies of the victims of the Walkerton, Ont. tainted drinking water tragedy have led researchers to discover DNA variations in genes that increase the risk of developing post-infectious irritable bowel syndrome (PI-IBS). The sheer scale of infection and the recording of the health of Walkerton’s citizens gave a team of researchers a unique opportunity to study the origin of this disorder.
Seventy per cent of Inuit preschoolers in Nunavut, Canada’s largest territory, live in households where there isn’t enough food, a situation with implications for children’s academic and psychosocial development, found McGill University Associate Professor and Canada Research Chair Grace Egeland of the Centre for Indigenous Peoples' Nutrition and Environment and collaborators.
McGill researcher discovers strong evidence of link between eating contaminated chicken and the E. coli that cause urinary tract infection
A groundbreaking study of couples, led by Professor Eduardo Franco found more than half (56 per cent) of young adults in a new sexual relationship were infected with human papillomavirus (HPV).
