Keys to the genome: unlocking the package
Scientists at the Montreal Clinical Research Institute have discovered the molecular mechanisms responsible for opening up the human genome and expressing new genes. Done in the laboratory of Jacques Drouin , director of the IRCM's Molecular Genetics Research Unit, the find marks an important step towards understanding the mechanisms underlying the genome.

Who does what better: a non-binary view
A research team led by UdeM's Robert-Paul Juster has shown that performance on some cognitive tasks is better predicted by gender identity than by sex assigned at birth. Many studies have found sex differences in cognitive abilities. In general, women outperform men on verbal and fine motor tasks, while men outperform women on spatial orientation and mental rotation tasks.

A promising discovery in a rare neurodegenerative disease
Imagine being middle aged and starting to feel that you are off balance a lot and that you are having a hard time coordinating your movements. Those are among the symptoms of Spinocerebellar ataxia type 6, known as SCA6, a rare neurodegenerative disease which typically appears in adulthood and worsens over time.

Cognitive performance at age four can be predicted in infancy
Cognitive performance at age four can be predicted in infancy
Based on the brain dynamics she observed in infants, UdeM doctoral candidate of psychology Florence Deguire was able to determine which would go on to have the best adaptive behaviours scores. Using electroencephalogram (EEG) data collected before the age of one, it is possible to predict which babies will have the highest adaptive behaviour scores at the age of four.

Direct communication path between the lungs and the brain
Direct communication path between the lungs and the brain
Findings show that communication can alter the way the brain functions and the way someone behaves University of Calgary researchers have discovered the lungs communicate directly with the brain when there is an infection. Findings show the brain plays a critical role in triggering the symptoms of sickness, which may change the way we treat respiratory infections and chronic conditions.

Species diversity promotes ecosystem stability
What maintains stability within an ecosystem and prevents a single best competitor from displacing other species from a community? Does ecosystem stability depend upon the presence of a wide variety of species, as early ecologists believed, or does diversity do the exact opposite, and lead to instability, as modern theory predicts? Resolving a long-standing debate among ecologists A new study from McGill University and the Max Planck Institute and published recently in Science suggests an answer to this question that has stood unanswered for half a century among ecologists.

Global wildlife study during COVID-19 shows rural animals are more sensitive to human activity
Global wildlife study during COVID-19 shows rural animals are more sensitive to human activity
Science, Health & Technology Lou Corpuz-Bosshart Plant-eating animals more active, carnivores more cautious around humans One of the largest studies on wildlife activity-involving more than 220 researchers, 163 mammal species and 5,000 camera traps worldwide-reveals that wild animals react differently to humans depending on where the animals live and what they eat.

Decoding sleep to reveal our state of health
On World Sleep Day, we look at how neuroscientist Valérie Mongrain studies sleep to help doctors diagnose Alzheimer's disease earlier and predict the onset of epileptic seizures. Sleep takes up almost one third of our life, yet many of its secrets remain unexplained. To penetrate the mystery, neuroscientists are trying to decipher some of the mechanisms of this basic biological function, so key to good health.

New way it replicates
A U.S.-Canada study co-led by UdeM researchers offers key understanding of Ebola virus replication and potential therapeutic targets. Scientists in Canada and the U.S. have discovered a new way in which Ebola - an often deadly virus affecting people mostly in sub-Saharan Africa - reproduces in the body.

Surprising bacterium from Canadian lake shines new light on ancient photosynthesis
Surprising bacterium from Canadian lake shines new light on ancient photosynthesis
From -failed- experiment to world-changing discovery, Waterloo PhD candidate turns unexpected bacterial sample into novel research Sometimes an experiment doesn't go as planned. That's science. But a -failed- experiment or unexpected results can be the avenue to a discovery you could never anticipate.

New study expands understanding of brain blood flow and neurological disorders
New study expands understanding of brain blood flow and neurological disorders
The hippocampus - a seahorse-shaped region of the brain which plays a particularly important role in cognitive aging and memory function - has been studied as a singular region for several years. However, there remains a gap in understanding the factors underlying ageor disease-related changes between the different regions of the hippocampus, or subfields, until now.

Research discovery advances our understanding of the brain
Research discovery advances our understanding of the brain
A discovery by a team of researchers at the University of Calgary offers new insight into how the brain works, particularly during defensive or exploratory behaviour. Dr. Patrick Whelan, PhD, principal investigator of the study, says the team was able to pinpoint specific neurons in the brains of mice that trigger movement based on the context of the situation.

Results for: Vaping and other lifestyle factors linked to frequent headaches in youth
UCalgary research looks at impact of several factors on frequent recurring headaches in kids and teens A University of Calgary-led study of associations between lifestyle and headaches in children and adolescents finds vaping and smoking cigarettes or cannabis is linked with frequent headaches, or headaches occurring more than once a week.

A model for the evolution of intelligence
McGill study finds ability to solve food puzzles is the only predictor of innovation, brain size in wild birds When certain species of wild birds and primates discover new ways of finding food in the wild, it can serve to measure their flexibility and intelligence.

Skin aging: a synergy between cigarette smoke and sunlight
Skin aging: a synergy between cigarette smoke and sunlight
Combined exposure of the skin to cigarette smoke and UV rays could accelerate premature aging . Research has already shown the consequences of cigarette smoke and sunlight separately. A team from Laval University and the Centre de recherche du CHU de Québec-Université Laval has now investigated the harmful interaction between cigarette smoke and UV rays, as humans are rarely exposed to a single environmental factor.

New study links placental oxygen levels to fetal brain development
New study links placental oxygen levels to fetal brain development
A new study shows oxygenation levels in the placenta, formed during the last three months of fetal development, are an important predictor of cortical growth (development of the outermost layer of the brain or cerebral cortex) and is likely a predictor of childhood cognition and behaviour.

Study sheds light on how neurotransmitter receptors transport calcium, a process linked with origins of neurological disease
McGill and Vanderbilt researchers describe for the first time the mechanism of calcium transport in ionotropic glutamate receptors that helps drive the cellular processes that lead to learning and memory A new study from a team of McGill University and Vanderbilt researchers is shedding light on our understanding of the molecular origins of some forms of autism and intellectual disability.

New study sheds light on synaptic calcium transmission, a process involved in certain neurological disorders
A research team from McGill and Vanderbilt Universities describes for the first time the mechanism of calcium transmission by ionotropic glutamate receptors, a mechanism that contributes to the cellular processes underlying learning and memory. In a new study , a research team from McGill and Vanderbilt Universities sheds light on the molecular origins of certain forms of autism and intellectual disability.

Researchers are using RNA in a new approach to fight HIV
Society learned about the value of mRNA during the COVID-19 pandemic when we saw scientists and medical professionals harness its power to deliver a vaccine for the virus within a year. Now, University of Waterloo pharmacy associate professor Emmanuel Ho has developed a novel nanomedicine loaded with genetic material called small interfering RNAs (siRNA) to fight human immunodeficiency virus (HIV) using gene therapy.
