More than a meteorite: The new clues about the demise of dinosaurs
McGill researchers challenge current understanding of dinosaur extinction by unearthing link between volcanic eruptions and climate change What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final blow to the ancient giants.

Seniors: move, stimulate your neurons, socialize!
Following a program of physical exercise combined with cognitive training can greatly help older people with mild cognitive impairment, a national study finds. Symptoms of mild cognitive impairment in the elderly can be slowed or even reversed if they follow a combined program of physical exercise and cognitive training, according to the results of a clinical study of 175 seniors diagnosed with the disorder.

Unlocking the impact of early-life adversity on brain function
Do adults with a history of childhood trauma have altered brain responses to psychological challenges? Previous studies indicated that this can occur in laboratory animals, but it has been unclear whether it occurs in humans. Now a team of scientists, led by researchers from McGill University, have found evidence that exposure to childhood adversity is associated with an altered ability to process stressful challenges and other emotional material.

Harnessing AI to help pinpoint cancerous tumours
University of Waterloo engineers use AI to advance cancer treatment monitoring Engineers from the University of Waterloo are harnessing artificial intelligence to help doctors better see and control a non-invasive cancer treatment and, in the process, save lives. Their imaging system will allow for the safer and more effective use of high-intensity, focused ultrasound to destroy a wide range of cancerous, often deadly, tumours.

Mapping the health of Canada’s lakes
UdeM biologists produce a first-ever social and ecological profile - in multicoloured map form - of over 600 of the country's lakes, identifying which need to be better preserved. Canada has more lakes than any country in the world - more than 900,000 - and its population depends on them for drinking water, water to irrigate crops, and water in which to fish, swim, and boat on.

Discovery of an antibody that stimulates the immune system to eliminate cancer cells
Major work led by Dr. André Veillette's team in collaboration with a group of researchers managed to identify a previously unknown way which prevents phagocytosis. Major work led by Dr. André Veillette's team at the Institut de recherches cliniques de Montréal (IRCM), in collaboration with a group of researchers, and just published in Nature Immunology , managed to identify a previously unknown way which prevents phagocytosis, which is a process that promotes the immune system's response to cancer.

The herpes virus could be transmitted through food
The virus that causes cold sores can survive and remain infectious for several hours on food or food-related surfaces . It is generally accepted that the virus responsible for cold sores is transmitted via saliva or direct contact with the lesions it causes. However, there are other potential transmission routes, according to a study published by a team from Université Laval in the Journal of Applied Microbiology .

New process for screening old urine samples reveals previously undetected ’designer drugs’
Science, Health & Technology Erik Rolfsen Researchers from the University of B.C. and the BC Provincial Toxicology Centre (BCPTC) have developed a more efficient way to find out which new 'designer drugs' are circulating in the community. In a study published today in Analytical Chemistry , they showed how high-resolution mass spectrometry can be used to analyze urine samples at scale and uncover molecules from emerging designer drugs that have been missed by conventional testing.

Expert insight: Asteroid samples may reveal information about the origins of the universe
The OSIRIS-REx mission is NASA's first mission to collect samples from an asteroid - in this case 101955 Bennu - and return to Earth. OSIRIS-REx is an acronym for Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer. The sealed capsule landed on Sept. 24 near Salt Lake City, Utah, a feat that was broadcast live by NASA.

Discovery of a new family of microbes in a northern lake with a unique ecosystem
Laval University scientists identify a new class of bacteria that plays a key role in one of Canada's most northerly lakes Lake A, located on Ellesmere Island in Canada's High Arctic, has been isolated from the world for millennia. "It's a kind of lost world, untouched by human disturbance. The environmental conditions are particularly favourable for the study of microorganisms and their potential," stresses Adrien Vigneron, former postdoctoral fellow in Warwick Vincent's North Sentinel team, and Connie Lovejoy, from the Faculty of Science and Engineering.

Older adolescents with physical and mental illnesses have lowest self-perceptions
Study has implications when planning the transition from pediatric to adult health services Faculty of Health The combination of physical and mental illness had a negative impact on self-perception among older adolescents, but not for younger ones, shows a new University of Waterloo study. Researchers found that compared to adolescents with a physical illness only, their self-concept - the image we have of ourselves - was lower, but that was not the case for younger adolescents.

Exercise gains stick after financial rewards fade, Western study shows
If you start exercising for the promise of a little extra money, you may keep up the habit even after the financial incentives are gone, new research from Western suggests. A study of more than 580,000 Canadians across three provinces using a step-counting app showed that even when the rewards were removed after a year, most participants continued to walk almost as much.

Seinfeld provides insight into how our brains understand and appreciate humour
If you have ever laughed at a joke despite not finding it funny, or laughed at something and weren't sure why, you have proven that comprehending and appreciating humour are two very different things. Western University neuroscientists have now discovered that two distinct parts of the brain trigger these reactions, a result that also may shed light on why some patients with Parkinson's disease might have difficulty being 'in' on a joke.
