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.

Pregnant women who have HPV rarely transmit it to their baby, and when they do, the infection does not persist. While human papilloma virus (HPV) is common in pregnant women, transmission from mother to baby is infrequent and the virus does not persist in infected newborns beyond six months.

Biomarkers for the Progression of Type 2 Diabetes Identified

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.
A UdeM researcher has found that teenage girls are more likely to experience momentary anxiety when their classmates are anxious. Boys are not. It is well known that adolescents tend to adopt the same behaviours as their peers. As Canadian students spend an average of 923 hours per school year in the company of their classmates, Sandrine Charbonneau wanted to see if there was any association between a student's "state" (momentary) anxiety and the "trait" (longer-term) anxiety of his or her classmates.
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.
Perinatal transmission of HPV: Encouraging new data
Pregnant women who have HPV rarely transmit it to their baby, and when they do, the infection does not persist. While human papilloma virus (HPV) is common in pregnant women, transmission from mother to baby is infrequent and the virus does not persist in infected newborns beyond six months.

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.

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.

What’s a park worth to the economy?
May 17, 2023 First of its kind study quantifies mental and physical health value of urban parks A new framework developed by University of Waterloo researchers demonstrates the significant economic health savings and benefits from urban park investments. In the first case study of its kind in Canada, researchers looked at Peterborough's new Quaker Foods City Square park, which cost taxpayers $6.4 million, and have estimated the economic value of physical and mental health benefits that could come from it at more than $4 million per year.

Team examined association between pain and DISH, a disease that causes calcification of the spine After hearing first-hand from patients about how the disease impacted their lives, a team of researchers and graduate students at Western were inspired to investigate the symptoms associated with an understudied spine disease called diffuse idiopathic skeletal hyperostosis (DISH).
An international clinical trial led by researchers at University Health Network (UHN) and the University of Toronto has shown that a new therapy for recurrent glioblastoma prolongs patient survival, in some cases by several years.
Astronomers from Université de Montréal have discovered an Earth-sized exoplanet around a nearby small red dwarf star that appears to be carpeted with volcanoes.

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.

Deep-sea impacts of climate interventions
Waterloo professor is part of an emerging field that calls for establishing a governance framework for ocean-based climate interventions Faculty of Environment From its current capacity as a carbon sink to its potential as a site for generating renewable energy, and managing solar radiation, the ocean is increasingly at the forefront of discussions around climate mitigation strategies. However, efforts to develop ocean-based climate interventions expose the ocean to various threats that harm biodiversity, pollute, and change its very chemistry.

May 15, 2023 Robots can help find objects you've lost, thanks to new 'artificial memory' Engineers at the University of Waterloo have discovered a new way to program robots to help people with dementia locate medicine, glasses, phones and other objects they need but have lost. And while the initial focus is on assisting a specific group of people, the technology could someday be used by anyone who has searched high and low for something they've misplaced.
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.

University of Toronto researchers developing AI system to tackle harmful social media content
Hate speech and misinformation on social media can have a devastating impact, particularly on marginalized communities. But what if we used artificial intelligence to combat such harmful content? That's the goal of a team of University of Toronto researchers who were awarded a Catalyst Grant by the Data Sciences Institute (DSI) to develop an AI system to address the marginalization of communities in data-centric systems - including social media platforms such as Twitter.

Workplace accidents are most likely to occur in moderately dangerous settings
People tend to underestimate the degree of safety behaviour needed in moderately dangerous conditions Although some people might expect very dangerous jobs to be associated with the highest incidence of workplace accidents, a new study finds that accidents are actually most likely to occur within moderately dangerous work environments.
