Even in athletes, obese BMI associated with worse concussion recovery

In a clinical trial led by University of Toronto researchers, an allogeneic stem cell–derived islet therapy (zimislecel) restored insulin production and ended severe hypoglycemia in adults with type 1 diabetes within a year of treatment.

A collaborative team of researchers has succeeded in revealing the high-resolution structures of amyloid β (Aβ40) fibrils carrying the Tottori-type familial mutation (D7N) by leveraging the microgravity environment aboard the International Space Station's "Kibo" module. Their paper is published in the journal ACS Chemical Neuroscience.

Why do some older adults easily remember the name of a new acquaintance or the location of their keys, while others struggle with everyday recall—despite appearing equally healthy?

Preterm birth complications are the primary cause of death among children under age 5, and nearly 75% could be prevented with interventions, according to the World Health Organization. While the causes leading to preterm birth are largely unknown, an interdisciplinary research team at Washington University in St. Louis has found that variability in sleep patterns in people experiencing pregnancy can effectively predict preterm birth.

We all like to imagine we're aging well. Now a simple blood or saliva test promises to tell us by measuring our "biological age." And then, as many have done, we can share how "young" we really are on social media, along with our secrets to success.

Ice baths and other cold-water plunges can help your body to burn more calories, but a new study published in Physiology & Behavior by researchers at Coventry University has found that it could actually make you eat more as well.

Students in health-related fields are benefiting from generative artificial intelligence (GenAI) in many areas of learning, but concerns about critical thinking and reduced peer interaction have come to light in a new systematic review conducted by Monash University.

Psychosis often begins not with characteristic disturbances of the mind—delusions like paranoia or hallucinations—but with disturbances in the way we move our body. For researchers like Indiana University Assistant Professor Alexandra Moussa-Tooks in the Department of Psychological and Brain Sciences, these motor disturbances offer critical insights into the condition of psychosis itself.

The pending Supreme Court challenge to the Affordable Care Act's preventive services mandate has serious implications for the future of the treatment of hepatitis C in the United States.

Children of fathers who were categorized as obese or overweight based on their body mass index (BMI) around the time of conception are more likely to develop obesity themselves, according to new research from the University of Toronto that is reshaping how we understand paternal influence on child health.

26 June 2025, Cairo, Egypt – On International Day Against Drug Abuse and Illicit Trafficking, marked on 26 June, the World Health Organization (WHO) is highlighting the drug trade’s devastating effects on the health and well-being of populations. Drug use impacts security, safety, and development, costing some countries up to 2% of their GDP due to health-related expenses, crime, and lost productivity. Beyond its economic burden, drug use constitutes a significant public health issue, linked to a range of health issues, including mental health conditions, hepatitis, tuberculosis, and cardiovascular diseases. Despite these public health implications, drug use has been overwhelmingly addressed through a law enforcement and supply restriction lens, using strategies that reinforce stigma and overlook the health dimensions of the issue. Globally, an estimated 292 million people (5.6% of those between 15 and 64) used drugs in 2022. There are 64 million individuals suffering from drug use disorders. In 2022, in the Eastern Mediterranean Region, an estimated 6.7% of the population aged between 15 and 64 years used drugs, and more than 3.4 million people suffered from drug use disorders. Despite the alarming levels of substance use, and the fact that investing in substance use treatment offers returns of between US$ 4–12 for every dollar spent, in 2022, only 1 in 11 individuals with drug use disorders globally, and 1 in 13 in the Region, received treatment. To reduce morbidity, mortality, and the social costs associated with substance use disorders, the WHO Regional Office for the Eastern Mediterranean launched the “Regional Flagship Initiative on Read more...

From Romulus and Remus—the myth of the twin brothers who founded the city of Rome—to the synchronized speech of Australia's "Twinnies" Paula and Brigette Powers, identical siblings have long inspired our fascination and imagination.

In May 2025, researchers announced that K.J. Muldoon, a baby boy born without the ability to process dietary protein properly, had become the first person to be treated with a customized gene-editing therapy. Based on a technology developed by Broad Institute core member David Liu's laboratory, the treatment is the first in a series of new medicines being tested to treat rare diseases by repairing patients' particular genetic misspellings.

Brightly colored, inexpensive and disposable electronic cigarettes and vapes continue to gain popularity. These devices turn flavored nicotine-containing liquid into a vapor that people inhale over hundreds or thousands of puffs—commonly called vaping.

A team of engineers at the University of California, Los Angeles, working with a colleague from K Medical LLC, has developed a pressurized mattress that reduces the likelihood of developing bed sores for bedbound patients. In their paper published in the journal Science Robotics, the group describes how they developed their new mattress and how it can be used to help patients.

The human brain is known to store various memories for long periods of time, progressively learning from new experiences and forming adaptive representations that ultimately guide decision-making and behavior. When people experience new things, their brain creates new memories and mental representations, without overwriting or deleting old ones.

Policymakers and drinkers are speaking different languages when it comes to alcohol consumption, according to new research.

Weak bones can have deadly consequences. Women often get bone density tests to screen for osteoporosis, yet many men don't even realize they are at risk until they suffer a major fracture.
