Video games: posing in 3D
An UdeM computer scientist and his PhD candidate have developed a tool for animators to use bitmap sketches to control how a character stands and moves in three dimensions. What's the best way to get 3D characters in videogames to look real and expressive? Two computer scientists at Université de Montréal have come up with answer: use simple bitmap sketches to make their poses more lifelike.

Researchers suggest ’home remedies’ to increase vaccine supply in Canada before next pandemic
COVID-19 has put a spotlight on Canada's pandemic preparedness, and led some experts and leaders to call for a new public agency that would be in charge of domestic vaccine production to increase self-sufficiency. But Paul Grootendorst , an associate professor at the University of Toronto's Leslie Dan Faculty of Pharmacy, says creating such an agency would be more trouble than it's worth.

Sebastian Goodfellow , an assistant professor in the University of Toronto's department of civil and mineral engineering, and his team have partnered with researchers at The Hospital for Sick Children (SickKids) to help detect and diagnose heart arrhythmias. The project, supported by grant from the Canadian Institutes of Health Research, aims to leverage techniques developed by Goodfellow and his colleague in their previous work, which involves using artificial intelligence (AI) to analyze seismic data.
Researchers identify how cells move faster through mucus than blood
Some cells move faster in thicker fluid - think honey versus water, or mucus as opposed to blood - because their ruffled edges sense the viscosity of their environment and adapt to increase their speed. That was one of the surprising findings in a new study published in Nature Physics by researchers from the University of Toronto, Johns Hopkins University and Vanderbilt University.

A research team led by Marc Amyot is assessing the environmental impact of building a dam on permafrost at Inukjuak, in collaboration with the Inuit community. The Innavik Hydro Project currently being built by the Pituvik Landholding Corporation in partnership with Hydro-Québec, Innergex Renewable Energy Inc.
The risk of infection during pregnancy has always been a concern, but the high rate of illness during the COVID-19 pandemic has highlighted the potential impact of infection on a developing brain. To better understand the long-term consequences, a new Western University study supported by Western's BrainsCAN, explored the effects of a pregnant person's immune response to a virus or bacteria on an unborn baby's brain development.
Many mammal species living in cold climates tend to have large bodies and short limbs to reduce heat loss - a general pattern known as Bergmann's rule. However, bats are the exception to the rule, displaying small body sizes in both hot and cold regions. A McGill-led team of researchers is shedding light on this long-standing debate over bats- body sizes and focus on why bats are seemingly non-conforming to ecogeographical patterns found in other mammals.
Imagine having to choose over and over between what you enjoy doing and the pain that it might cause you, whether physical or emotional. If you live with conditions such as depression, anxiety, or chronic pain, you are probably familiar with making these difficult choices on a daily or weekly basis. But surprisingly little is known about which areas of the brain are involved in decisions of this kind.
Just like honey slowly dripping from a spoon, parts of the rocky outermost layer of Earth's shell are continuously sinking into the more fluid layer of the planet's mantle over the course of millions of years. Known as lithospheric dripping - named for the fragmenting of rocky material that makes up Earth's crust and upper mantle - the process results in significant deformations at the surface such as basins, folding of the crust and irregular elevations.
New map shows where fracking-induced earthquakes could hit in Canada
Maps help us to better understand and predict induced seismicity during subsurface engineering processes Scientists from the University of Waterloo have developed a map showing which regions and population centres of Western Canada are likely to experience earthquakes induced by underground energy extraction.

Even as gas prices soar, most people don't destroy their car's engine just to save energy - and that's one luxury certain insects have that those humans don't. New research from Western University has found potato beetles can break down and regrow muscles on demand, allowing them to preserve energy over the winter.
A new study co-authored by Western researchers found Ontario adults experienced poor sleep quality during the early months of the COVID-19 pandemic. The study, published in Sleep Medicine in March 2022, is part of a larger longitudinal study focusing on chronic disease among Ontario adults during the pandemic.
University of Toronto researchers in the Faculty of Applied Science & Engineering have grown a small-scale model of a human left heart ventricle in the lab. The bioartificial tissue construct is made with living heart cells and beats strongly enough to pump fluid inside a bioreactor. In the human heart, the left ventricle is the one that pumps freshly oxygenated blood into the aorta, and from there into the rest of the body.
Differential mortality of females would cause them to be three times less numerous than males when the population reaches a low point The intriguing cyclical variations of lemmings continue to surprise. The few answers that shed some light on this elusive phenomenon raise new questions that further thicken the mystery.
Science, Health & Technology Brett Goldhawk Levels of air pollution well below national and international air quality guidelines are associated with an increased risk of death, according to a new Canada-wide study led by researchers at the University of British Columbia. The study , published today in a Health Effects Institute (HEI) report, provides an in-depth analysis of air pollution levels across Canada and their relationship with mortality.
Astronomers at McGill University, MIT and elsewhere have detected a strange and persistent radio signal from a far-off galaxy, that appears to be flashing with surprising regularity. Classified as a fast radio burst, or FRB, this new signal persists for up to three seconds, about 1,000 times longer than the average FRB.
Greenhouse gas production is significantly less when biobased residues like compost replaces widely used nitrogen fertilizer during spring freeze-thaw events in cold temperate regions. A new study led from the University of Waterloo discovered greenhouse gas production is significantly less when biobased residues like compost replaces widely used nitrogen fertilizer during spring freeze-thaw events in cold temperate regions.
When two massive volcanic eruptions blanketed New Zealand in ash, they forever changed the genetics of the brown kiwi bird, a new study from the University of Toronto Scarborough has found. The brown kiwi are split into four distinct lineages that inhabit different parts of New Zealand's North Island.
Fighting climate change with deep-sea water
Microbes deep down in the ocean could be a good tool to transform carbon into more stable molecules, a laboratory study at UdeM suggests. Marine biologists have long known the power of microbes to transform carbon released by surface phytoplankton - algae on the surface of the sea - into more stable molecules.

Researchers are a step closer to understanding how Parkinson's disease develops and progresses thanks to chemical biological tools developed at Simon Fraser University. New research, published this week in the Proceedings of the National Academy of Sciences of the USA, and spearheaded by SFU researchers Matthew Deen and Yanping Zhu, outlines new technology and methods to measure the activity of lysosomal glucocerebrosidase (GCase), an enzyme that is commonly linked to Parkinson's disease.
