An UdeM-led study finds that cisgender teenage girls are less likely to achieve orgasm than teenage boys. Among cisgender Quebec teenagers - that is, those whose gender identity matches their sex assigned at birth - girls are significantly less likely than boys to achieve orgasm, either through masturbation or with a partner.

A study explores how variations in the copy number of certain DNA segments can influence cognitive abilities and neurodevelopment. A significant advancement in knowledge of the link between cognition and genetics has been made thanks to a study led by Université de Montréal graduate students Guillaume Huguet and Thomas Renne, working under the supervision of medical geneticist Sébastien Jacquemont, an associate professor of pediatrics and a researcher at the UdeM-affiliated CHU Saint-Justine.

Researchers led by an UdeM architecture professor look at how fear, anger and pride combine to shape responses to climate risks in four Latin American communities. Cecilia lives in Carahatas, a coastal village in Cuba threatened by rising sea levels caused by climate change. Experts predict that part of the village could be under water within 50 years.

In an international effort, researchers at Western, the University of Maryland School of Dentistry (UMSOD) and Neuroscience Research Australia (NeuRA) uncovered how specific patterns in brain activity can predict an individual's sensitivity to pain, expanding opportunities for improved pain management strategies.

Researchers working with mice discover novel brain mechanism, potentially identifying new targets for treatment A brain rhythm working in tandem with the body's natural sleep-wake cycle may explain why bipolar patients alternate between mania and depression, according to new research. The McGill University-led study published in Science Advances marks a breakthrough in understanding what drives shifts between the two states, something that, according to lead author Kai-Florian Storch , is considered the "holy grail" of bipolar-disorder research.

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.
