Biodegradable gel shows promise for cartilage regeneration
Biodegradable gel shows promise for cartilage regeneration
Science, Health & Technology Alex Walls A gel that combines both stiffness and toughness is a step forward in the bid to create biodegradable implants for joint injuries, according to new UBC research. Mimicking articular cartilage, found in our knee and hip joints, is challenging. This cartilage is key to smooth joint movement, and damage to it can cause pain, reduce function, and lead to arthritis.

Probiotics positively influence honeybee health, Western research finds
Probiotics positively influence honeybee health, Western research finds
Research team studies how changing honeybee gut microbiota contributes to hive health and influences social behaviour Widespread pesticide-use and diminished floral diversity in the environment have contributed to the worsening susceptibility of honeybees to infectious disease, threatening their support of adequate pollination of food crops.

Moving towards a more inclusive approach to medicine
Release of pangenome representing wide diversity of individuals ushers in new understanding of human biology and disease The first human genome, which has served as the reference until now, was released approximately 20 years ago. It was a landmark accomplishment that had a huge impact on biomedical research and changed the way scientists study human biology.

Highschool student partners with SFU music specialist to research the developing teenage brain
Highschool student partners with SFU music specialist to research the developing teenage brain
When Burnaby eighth grader Advaith S. Iyer decided to participate in the Greater Vancouver Regional Science Fair (GVRSF) for the first time this spring an ambitious research idea emerged. Seeking to test the cognitive load - the amount of work the brain is doing - associated with playing musical instruments, his high school laboratory equipment was insufficient for his complex experiment.

Bird brains can flick switch to perceive Earth's magnetic field  
Bird brains can flick switch to perceive Earth’s magnetic field  
Understanding how animals make their way around in the world helps determine things humans are doing that might influence them Earth's magnetic field, generated by the flow of molten iron in the planet's inner core, extends out into space and protects us from cosmic radiation emitted by the Sun. It is also, remarkably, used by animals like salmon, sea turtles and migratory birds for navigation.

Mapping the genetic history of French Canadians through space and time
Mapping the genetic history of French Canadians through space and time
First study to incorporate genealogical records to provide an accurate map of genetic relatedness Though we all share common ancestors ranging from a few generations to hundreds of thousands of years, genealogies that relate all of us are often forgotten over time. A new McGill University-led study is now providing insight into the complex relationship between human migration and genetic variation, using a unique genealogical dataset of over five million records spanning 400 years to unravel the genetic structure of French Canadian populations.

Vitamin K helps protect against diabetes
After 15 years of basic research, researchers at UdeM and the IRCM identify a new role for the blood-clotting micronutrient in helping to prevent a disease affecting one in 11 people. Canadian researchers have identified a new role for vitamin K and gamma-carboxylation in beta cells and their potentially protective role in diabetes, achieving a first in 15 years of basic research.

Mimicking brain plasticity in children to control post-traumatic stress
Mimicking brain plasticity in children to control post-traumatic stress
The CHU Sainte-Justine team, led by Graziella Di Cristo, has made an important breakthrough in the treatment of people suffering from symptoms associated with post-traumatic stress. Could we temporarily increase brain plasticity in adults to decrease fear and anxiety responses in people who have experienced trauma? CHU Sainte-Justine Neuroscientist Graziella Di Cristo and her team were determined to find out.

Microplastics are harming gut health
Microplastic pollution is altering the gut microbiomes of wild seabirds, and humans should be wary too Scientists have been worried about the potential harms of microplastics for years. These small plastic particles less than 5 mm in length have been found everywhere because of plastic pollution - from the Earth's deep oceans to remote regions in Antarctica, and even the seafood we eat.

A new understanding of human origins in Africa
Contemporary DNA evidence suggests that humans emerged from the interaction of multiple populations living across the continent There is broad agreement that Homo sapiens originated in Africa. But there remain many uncertainties and competing theories about where, when, and how.

Found: the mutated gene behind mirror movement disorder
In an advance that could pave the way for better diagnostics, Canadian scientists identify a new genetic mutation thought to cause the rare condition, which impairs coordination. Scientists at Université de Montréal, McGill University and its affiliated Montreal Children's Hospital have made a promising breakthrough in understanding the origins of mirror movement disorder, a rare inherited neurological disorder.

Tiny proteins found across the animal kingdom play a key role in cancer spread
Phosphatases of regenerating liver (PRLs) are a family of enigmatic proteins involved in cell growth and metabolism present in various species. From humans to fruit flies, they play a unique role in the growth of cancerous tumours and the spread of cancer throughout the body. New research emerging from McGill University is contributing to what is known about PRLs, which could potentially become an important tool in the development of cancer-fighting treatments.

Nature favours creatures in largest and smallest sizes
Surveying the body sizes of Earth's living organisms, researchers from McGill University and University of British Columbia found that the planet's biomass - the material that makes up all living organisms - is concentrated in organisms at either end of the size spectrum. The researchers spent five years compiling and analyzing data about the size and biomass of every type of living organism on the planet-from tiny one-celled organisms like soil archaea and bacteria to large organisms like blue whales and sequoia trees.

Understanding and changing how we see ourselves
May 9, 2023 New neurocognitive model for understanding - and changing - how we see ourselves and the world could improve therapies for treating mental health By Elizabeth Rogers and Zoe Tipper Faculty of Arts Throughout our lives, our experiences shape how we view ourselves and the world around us. These views, known in psychology as schemas, can negatively impact our mental health and be difficult to change.

The Dungeness crab is losing its sense of smell, putting it at risk - and climate change may be to blame
A new study by researchers at the University of Toronto finds that climate change is causing a commercially significant marine crab to lose its sense of smell, which could partially explain why their populations are thinning.

New hope for vision regeneration
Researchers led by UdeM's Michel Cayouette have found a way to reactivate dormant cells in the retina and transform them to ultimately replace cells lost in retinal degeneration. Dr. Michel Cayouette, Director of the Cellular Neurobiology Research Unit at the Clinical Research Institute of Montreal (CRIM) and Full Professor at the Faculty of Medicine of the Université de Montréal Credit: Amélie Philibert There's new hope for potentially restoring vision in patients suffering from degenerative retinal disease, thanks to work by researchers at Université de Montréal.

Generative AI to design novel proteins
Generative AI to design novel proteins
Researchers at the University of Toronto have developed an artificial intelligence system that can create proteins not found in nature using generative diffusion - the same technology behind popular AI image-creation platforms such as Midjourney and OpenAI's DALL-E. The system will help advance the field of generative biology, which promises to speed up drug development by making the design and testing of entirely new therapeutic proteins more efficient and flexible.
