A current controversy raging in evolutionary biology is about whether adaptation to new environments is the result of many genes, each of relatively small effect, or just a few genes of large effect. A new study published in Molecular Ecology by McGill biologist Andrew Hendry and a colleague from Basel University strongly supports the first “many-small” hypothesis.
Nearly one in five people suffers from the insidious and often devastating problem of chronic pain. That the problem persists, and is growing, is striking given the many breakthroughs in understanding the basic biology of pain over the past two decades. Research published online in Nature Medicine points to potential solutions.
Nine McGill researchers were among the 132 newly awarded or renewed Canada Research Chairs just announced by the Honourable Gary Goodyear, Minister of State for Science and Technology. The McGill CRCs work in fields ranging from social statistics and family change to the cognitive neuroscience of attention and expectation.
In a study published in Nature, Alfonso Mucci, of the Department of Dept. of Earth and Planetary Sciences worked with colleagues from Concordia University to study the chemical makeup of sediment samples from oceans around the world to show how iron oxides can remove carbon dioxide from our atmosphere.
For those involved in managing the fallout from environmental disasters such as oil spills, it is essential to have tools that predict how the oil will move. McGill Engineering professor George Haller has worked with Prof. Josefina Olascoaga,from the University of Miami to develop a method that does not simply track: it actually forecasts major changes in the way that oil spills will move.
A recent study led by Gergely Lukacs, a professor at McGill University’s Faculty of Medicine, Dept. of Physiology, and published in the January issue of Cell, has shown that restoring normal function to the mutant gene product responsible for cystic fibrosis requires correcting two distinct structural defects. This finding could point to more effective therapeutic strategies for CF in the future.
McGill University and Freie Universität Berlin have formally moved to enhance their research collaboration through a cooperation agreement that includes the exchange of faculty, staff and students, as well as joint research activities and publications.
A research group led by Dr. A. Claudio Cuello of McGill University’s Faculty of Medicine, Dept. of Pharmacology and Therapeutics, has uncovered a critical process in understanding the degeneration of brain cells sensitive to Alzheimer’s disease (AD). The study, published in the February issue of the Journal of Neuroscience, suggests that this discovery could help develop alternative AD therapies.
A new study conducted by researchers from McGill University, the Research Institute of the McGill University Health Centre (RI MUHC), and Sainte-Justine University Hospital Research Centre, has put the accuracy of rapid influenza diagnostic tests (RIDTs) under the microscope. The meta-analysis of 159 studies showed three key findings.
Human activity is likely a greater threat to coastal groundwater used for drinking water supplies than rising sea levels from climate change, according to a study conducted by geoscientists from the University of Saskatchewan and McGill University in Montreal.
A research team led by neuroscientists Drs. Daniel Levitin and Vinod Menon, from McGill and Stanford Universities, analyzed the scores of close to 2,000 musical compositions written by more than 40 composers over the last 400 years in a large variety of Western musical genres. They discovered a mathematical formula governing the rhythmic patterns to which every single piece of music conformed.
A team of researchers led by McGill neuroscientist Terence Coderre, who is also affiliated with the Research Institute of the McGill University Health Centre, has found the key to understanding how memories of pain are stored in the brain. More importantly, the researchers are also able to suggest how these memories can be erased, making it possible to ease chronic pain.
Could depression in adulthood be tied to a parent’s level of education? A new study led by Amélie Quesnel-Vallée, a medical sociologist from McGill University, suggests this is the case.
