The largest population genome sequencing effort to date is published today in Nature. Based on data collected by the UK10K project, the study was designed to explore the contribution of rare genetic variants to human disease and its impact on risk factors. Rare genetic variants are changes in DNA that are carried only by relatively few people in a population.
It is estimated that half of all cancer patients suffer from a muscle wasting syndrome called cachexia. Cancer cachexia impairs quality of life and response to therapy, which increases morbidity and mortality of cancer patients. Currently, there is no approved treatment for muscle wasting but a new study from the Research Institute of the McGill University Health Centre (RI-MUHC) and University of Alberta could be a game changer for patients, improving both quality of life and longevity. The research team discovered a new gene involved in muscle wasting that could be a good target for drug development.
"Usually, the stars at the centers of galaxy clusters are old and dead, essentially fossils," said Tracy Webb of McGill University, Montreal, Canada, lead author of a new paper on the findings accepted for publication in the Astrophysical Journal. "But we think the giant galaxy at the center of this cluster is furiously making new stars after merging with a smaller galaxy."
Not even close to every person who faces challenges or lives with severe depression commits suicide. Some people are more vulnerable than others.
Low levels of vitamin D significantly increase the risk of developing multiple sclerosis (MS), according to a study led by Dr. Brent Richards of the Lady Davis Institute at the Jewish General Hospital, and published in PLOS Medicine. This finding, the result of a sophisticated Mendelian randomization analysis, confirms a long-standing hypothesis that low vitamin D is strongly associated with an increased susceptibility to MS. This connection is independent of other factors associated with low vitamin D levels, such as obesity.
The atmosphere is so unstable that a butterfly flapping its wings can, famously, change the course of weather patterns. The celebrated “butterfly effect” also means that the reliability of weather forecasts drops sharply beyond 10 days.
Ontario high school students Alexander Deans and Aditya Mohan have been named McGill University’s most recent recipients of the prestigious Schulich Leader Scholarships.
In a large study analyzing 20 years of data from Quebec, a team from the Research Institute of the McGill University Health Centre (RI-MUHC) has demonstrated that gestational diabetes signals future diabetes risk not only in mothers, but also in fathers. The study was recently published in Diabetes Care.
Scientists at the Montreal Neurological Institute and Hospital -The Neuro, at McGill University and the McGill University Health Centre, have made a breakthrough in understanding an important protein that appears to act as a kind of cellular “marriage broker.” The protein called Netrin1 brings cells together and maintains their healthy relationships. Netrin1 plays an essential role in the growth of the human organism, directing cell migration and the formation of cell circuits both at the embryo stage and after birth.
Insecticides that are sprayed in orchards and fields across North America may be more toxic to spiders than scientists previously believed.
Even jumping spiders have personalities scientists have discovered. A "shy" individual will not make the same choices as a "bold" individual. This means that some individuals, because of their personality type, will capture more prey than others, and will therefore have a larger effect on local ecosystems.
A new study published in the journal Molecular Psychiatry by a team led by Salah El Mestikawy, Ph.D., researcher at the Douglas Mental Health University Institute (CIUSSS de l’Ouest-de-l’île-de-Montréal), professor at McGill University and head of research at CNRS INSERM UPMC in Paris, opens the field to new understanding of the molecular mechanism underlying addiction in humans.
Researchers at McGill have clearly identified, for the first time, the specific parts of the brain involved in decisions that call for delayed gratification.
