Despite ongoing global pollution, researchers have discovered that levels of mercury in seabirds off the coast of B.C. have remained relatively stable over the past 50 years. Surprisingly, mercury in seabirds is now actually slightly lower. This might appear to be good news, but unfortunately it is due to a decline in fish stocks near the surface which has forced seabirds to change their diet, and in the process to feed in areas low in bacteria (known as sulfate-reducing bacteria) which act to control the levels of mercury in their bodies.
Researchers have linked a debilitating neurological disease in children to mutations in a gene that regulates neuronal development through control of protein movement within neuronal cells.
By Shawn Hayward, Montreal Neurological Institute Researchers at the Montreal Neurological Institute of McGill University are playing key roles in uncovering the mechanisms underlying ALS and will share in $3.9 million, part of $4.5 million in research funding announced on Nov. 23 by the ALS Society of Canada in partnership with Brain Canada.
Scientists have identified a gene in the French-Canadian population that predisposes them to the development of intracranial aneurysm (IA), a potentially life threatening neurological condition that is responsible for approximately 500,000 deaths worldwide per year, half of which occur in people less than 50 years of age. Using genetic analysis, the team of researchers found rare variations of one gene, RNF213, that appeared more frequently in IA patients than in the control group. Both patients and the control group came from French-Canadian families.
To the naked eye, ancient rocks may look completely inhospitable, but in reality, they can sustain an entire ecosystem of microbial communities in their fracture waters isolated from sunlight for millions, if not billions, of years. New scientific findings discovered the essential energy source to sustain the life kilometres below Earth’s surface with implications for life not only on our planet but also on Mars.
Each year, about 500,000 North Americans get dental implants. If you are one of them, and are preparing to have an implant, it might be a good idea to start taking beta blockers, medication that controls high blood pressure, for a while. And to stop taking heartburn pills. A body of research from McGill led-teams indicates that in order to raise the odds that dental implants will attach properly, there are clear benefits to taking certain common medications and avoiding others. Bone cell growth, healing and death
There is widespread worry today about the health effects of just about everything around us -- from the food we eat and water we drink, to the plastics we use and medications we take. A journalist’s task of sorting through all the latest studies and reporting the findings in a responsible fashion is more critical than ever.
With global temperatures continuing to rise at an alarming rate, predictions for the impact of climate change on plants and wildlife must improve to give scientists a clearer picture of which species are most at risk of extinction.
A new outdoor laboratory will serve as a facility for studying the effects on our lakes of climate change and chemicals commonly used in Quebec. It features a series of 96 experimental ponds containing 1,000 litres of water from Lac Hertel on McGill University’s Gault Nature Reserve in Mont St. Hilaire. This network of ponds, named LEAP (Large Experimental Array of Ponds), was opened on September 2, 2016.
Researchers now have the capability to build virtual reality worlds that can be inhabited by both lab animals (like rats and monkeys) and humans, allowing for a sort of cross-species brain research that’s never really been possible before, as different species are run through virtual environments in video games while scientists study brain activity… In a new study, published in Journal of Neuroscience Methods, a team of neuroscientists—including Martinez-Trujillo, Roberto Gulli and Guillaume Doucet, who are both also affiliated with McGill University—describe a new virtual reality “toolbox”

As governments struggle to keep pace with rapid advancements in science and technology, a new report by the Institute for Research on Public Policy (IRPP) and the Canadian Academy of Engineering (CAE) outlines how governments can better incorporate that knowledge in policy-making processes and improve the quality of government decisions.
