A new study led by Western researchers found frequent treatment with intranasal oxytocin - a hormone in the brain associated with empathy - offers promise for addressing a key symptom among patients with frontotemporal dementia (FTD): Apathy. It's a common issue among those with FTD which affects the frontal and temporal lobes of the brain, impacting language, behaviour and decision making.

Stays of six months to a year in weightlessness on the International Space Station affect ocular biomechanics, but the changes don't last, according to a study led by UdeM's Santiago Costantino. The low levels of gravity (microgravity) in space cause significant changes in astronauts' eyes and vision after six to 12 months aboard the International Space Station (ISS).

A molecule already used for different purposes in humans could improve post-vaccination immune memory The RNA vaccine against COVID-19 has many qualities, but it has one shortcoming that has escaped no one's notice: the protection it confers is short-lived, hence the need for frequent booster doses.

A single gene that regulates testosterone levels in a "crazy" species of shore bird controls the development of three wildly different types of males, an international study involving researchers at Simon Fraser University has found. Ruffs have long fascinated scientists for their three types of males, known as morphs, that differ radically from each other in appearance and mating behaviours.

UdeM scientists are combining immersive imagery and hypnotic techniques to reduce pain and anxiety in patients who have cancer of the blood. In a room at Maisonneuve-Rosemont Hospital in Montreal, a patient puts on a virtual reality (VR) headset. Bright bubbles float slowly up and down before his eyes while soothing sounds play in the background.

McGill astronomers place FRB 20240209A in a region of space associated with a 'dead' galaxy, one that is no longer forming stars Astronomers studying the origins of enigmatic fast radio   bursts (FRBs) have made a groundbreaking discovery that could transform our understanding of the universe's most powerful and mysterious signals.

Boys exposed to violent screen content in the preschool years were more likely to become antisocial and violent themselves a decade later, in their mid-teens, a new study shows. Results of new study led by Linda Pagani, Professor at the Université de Montreal's School of Psychoeducation, show long-term associated risks of early exposure to violent content in childhood and later teen antisocial behavior, more than a decade later.

McGill discovery has potential applications in fields ranging from aerospace exploration to next-generation soft robots Finding new angles on an old artform, McGill researchers have increased the num

Scientists at UdeM and its affiliated research institute IRIC have developed a new drug-discovery platform for high-risk leukemias in children - with promising results.

A long-standing question about when archaic members of the genus Homo adapted to harsh environments such as deserts and rainforests has been answered in a new research paper. The study , published in Nature Communications Earth and Environment , finds it was earlier than originally thought. "We reveal how early humans - known as hominins - were able to thrive under harsh conditions," says lead author Dr. Julio Mercader , PhD, a professor in both the Faculty of Arts and the Faculty of Science at the University of Calgary.

Study of fully vaccinated children finds a link between stunted growth and weakened immunity, suggesting combatting child hunger could help prevent the disease's spread Amid a global surge in measles cases, new research suggests that undernutrition may be exacerbating outbreaks in areas suffering from food insecurity.

While greenhouse gases continue to cause temperatures to rise, a reduction in low-cloud cover over land serves as a natural brake: study McGill researchers have discovered that changes in clouds are slightly mitigating global warming. While greenhouse gases continue to cause temperatures to rise, a reduction in low-cloud cover over land has brought about a modest reduction of the amount of heat being trapped close to ground level.

Two UCalgary researchers part of University of New South Wales team that created a 'Schrödinger's cat' inside a silicon chip A team led by quantum engineers at the University of New South Wales - that includes two UCalgary researchers - has demonstrated a well-known quantum thought experiment in the real world.

Professor Juan Carlos Villarreal believes it's time to pay more attention to so-called inferior plants Two recently published studies by a research team that includes Université Laval's Juan Carlos Villarreal demonstrate that modest, little-known plants can provide valuable fundamental knowledge about the evolution of life on Earth, and inspire innovations that can increase agricultural production.

In new study, MRI combined with machine learning reveals presence of cancer cells with 85-per-cent accuracy Researchers have developed an artificial intelligence (AI) model to detect the spread of metastatic brain cancer using MRI scans, offering insights into patients' cancer without aggressive surgery.

Western researchers have developed a novel technique using math to understand exactly how neural networks make decisions - a widely recognized but poorly understood process in the field of machine learning. Many of today's technologies, from digital assistants like Siri and ChatGPT to medical imaging and self-driving cars, are powered by machine learning.

Imagine controlling apps with your feet while you walk. This concept is the focus of new research which explores using gait gestures - intentional variations in how you walk - as controls for augmented reality (AR) devices. "There's a long history of using feet to control machines. For example, the pedals on the car, but very little research has been done into using the way we walk as an input for a device," said Ching-Yi Tsai, the lead author on the study and a former visiting scholar in the University of Waterloo David R. Cheriton School of Computer Science.

Researchers uncovered a prehistoric ecosystem teeming with giant marine reptiles, uncovering unmatched food web complexity  Predators at the top of a marine food chain 130 million years ago ruled with more power than any modern species, McGill research into a marine ecosystem from the Cretaceous period revealed.

According to a new study, people who regularly go to the sauna enjoy better physical and mental health than people who don't. Why? Because of the heat. Going to the sauna offers the prospect of a cozy wooden space, where both mind and body can shelter from the pressures of daily life. The enjoyable aspects of this centuries-old ancestral practice have are known around the world.

Microplastics can go right through wastewater treatment plants, and researchers have engineered bacteria commonly found in there to break down this pollution before it can persist in the environment. Researchers from the University of Waterloo added DNA to several species of bacteria found in wastewater, allowing them to biodegrade polyethylene terephthalate (PET), a common plastic found in carpet, clothing and containers for food and beverages.
