Worldwide fertility crisis: why men really need a hand from science
A consortium of international experts gives 10 recommendations to increase the chances that men will experience the joys of fatherhood and have healthy children. Infertility now affects one in six couples of reproductive age according to the World Health Organisation. About half the time, it originates from men.

How do marine worms adapt to deep-sea conditions?
How do marine worms adapt to deep-sea conditions?
DNA sequencing of marine worms has revealed how they adapt to life 2,500 metres below the ocean's surface, where they experience extreme pressure conditions and temperature fluctuations. Maeva Perez is fascinated by marine worms. Her first encounter with these cold-blooded invertebrates dates back to her time at the University of Victoria, in British Columbia, where she was completing a master's in biology.

Stress, depression and... astrocytes
On World Mental Health Day, we look at how Ciaran Murphy-Royal and his research team work to prevent depression by acting on brain cells. The scientific literature is clear: chronic stress experienced in childhood increases the risk of illness in adulthood - everything from obesity and cancer to dependence and depression.

Fear of human 'super predator' pervades South African savanna
Fear of human ’super predator’ pervades South African savanna
New study: Fear of human "super predator" pervades South African savanna Elephants, rhinos, giraffes and other wildlife dread people far more than lions Lions have long been considered the world's most fearsome predator, the "king of beasts," but according to a new study, fear of humans far exceeds that of lions in elephants, rhinos, giraffes and every other mammal across the African savanna.

Bees around the apple trees
Bees around the apple trees
An international study has characterized the diversity of bees in apple orchards across the globe. By carrying pollen from flower to flower, pollinator insects play an essential role in the reproductive cycle of flowering plants. Bees do more of it than any other, both here in Canada and around the world.

Can a simple eye exam help diagnose autism?
Researchers studied a cohort of 400 children aged 9 to 10 in New Zealand who exhibited a full range of possible autism traits and conducted a variety of vision and visuomotor processing tests with them. Females are often underdiagnosed with being on the autism spectrum because they often mask their symptoms more successfully than males.

Fainting from needles may be alleviated by reducing pain - study
Feeling faint after your booster shot? A team of SFU researchers found that needle pain may increase the conditions that lead some people to faint. In a recent paper published in the journal Clinical Autonomic Research , the researchers suggest those with a fear of needles or history of fainting could benefit from topical anesthetics to help reduce the pain.

Assessing unintended consequences in AI-based neurosurgical training
Machine learning tutors affect learners in unforeseen ways, both positive and negative Virtual reality simulators can help learners improve their technical skills faster and with no risk to patients. In the field of neurosurgery, they allow medical students to practice complex operations before using a scalpel on a real patient.

HIV: two autopsies reveal where the virus hides
HIV: two autopsies reveal where the virus hides
A Canadian research team shows for the first time that HIV reservoirs are concentrated in the spleen and lymph nodes, and that they can travel throughout the body. A small number of HIV-infected cells remain in the tissues of people living with the virus and who are undergoing antiretroviral therapy.

AI to predict recovery after serious brain injury
AI to predict recovery after serious brain injury
Two graduate students from Western University have developed a ground-breaking method for predicting which intensive care unit (ICU) patients will survive a severe brain injury. Matthew Kolisnyk and Karnig Kazazian combined functional magnetic resonance imaging (fMRI) with state-of-the art machine learning techniques to tackle one of the most complex issues in critical care.

Breakthrough on preeclampsia cure
Breakthrough on preeclampsia cure
Researchers have made groundbreaking progress towards identifying the root cause and potential therapy for preeclampsia. The pregnancy complication affects up to eight per cent of pregnancies globally and is the leading cause of maternal and fetal mortality due to premature delivery, complications with the placenta and lack of oxygen.

COVID infections in animals - a key to the ongoing trajectory of the pandemic?
COVID infections in animals - a key to the ongoing trajectory of the pandemic?
Tracking viral transmissions between humans and animals could help identify successful mutations The COVID-19 pandemic was probably caused by the transmission of the SARS-CoV-2 virus from animals to humans, and it has been reported anecdotally that the virus can pass from humans to different animal species, too.

How we see the world
A team of Montreal scientists identifies an important new mechanism that's key to helping humans see in 3D. Scentists in Montreal have identified a key mechanism involved in the growth of nerve cells that are critical to mediate binocular vision, which allows people to see the world in three dimensions.

Meet the innovators creating affordable tech for low-resource communities 
At Western, researchers have been working on innovations in health care intended for communities in resource-constrained environments. The Frugal Biomedical Innovations Program has launched 15 catalyst grants to support these innovations, which will help in diagnosis of diseases and in therapy, while costing less to operate or maintain.

Study suggests cannabis use during pregnancy could cause lifelong cognitive deficits
Western researchers also find impact of prenatal cannabis exposure on cognition and memory differs by sex While previous research has shown that prenatal cannabis exposure can obstruct the normal growth of a fetus, the long-term impacts on brain development are still unknown. Western researchers are now providing fresh insight into this area, while also identifying a possible direction to treat the adverse effects.

Researchers partner on interdisciplinary salmon conservation
Reversing a 40-year decline in Pacific salmon populations requires a collaborative approach that combines traditional Indigenous knowledge with archaeology and genomics. A new project, funded by Genome BC, involves a team of researchers from the Tsleil-Waututh Nation, Simon Fraser University's Department of Archaeology and the University of British Columbia's Institute for the Oceans and Fisheries.

What happened to the eggs?
Veterinary scientists at UdeM think they've unlocked a key reason behind infertility in women: they have too little of an important protein called SF-1. Epidemiological studies have shown that infertility affects 12 to 15 per cent of couples of reproductive age in developed countries, and at least 25 per cent in underdeveloped ones - overall, 186 million people worldwide.

Progressing undetected for years
A team of Université de Montréal scientists tries to better understand the resilience of the brain during the asymptomatic period of Parkinson's disease - and makes a surprising finding. Have you or someone close to you just been diagnosed with Parkinson's disease? Well, chances the disease has been progressing quietly but insidiously for more than 10 years, new research shows.

Hidden gene pokes holes in preconceptions
Professor Sophie Breton and her team have discovered a hidden gene in the human mitochondrial genome. Mitochondrial DNA, with its relatively small number of base pairs (around 16,000 compared with 3 billion in nuclear DNA), was sequenced almost 45 years ago. "Once mitochondrial DNA was sequenced, it didn't take long to go through it," said Sophie Breton, a professor in Université de Montréal's Department of Biological Sciences.
