AI adoption in medicine is accelerating: More than 12,000 primary care clinicians have enrolled in Canada Health Infoway’s national AI scribe program, about 5,000 Ontario physicians use AI scribes and roughly one in five Canadian physicians now use AI tools. Almost 60% report a cut in administrative time.

A needle-free vaccination method protected mice against the viruses that cause COVID-19 and flu, offering a possible new way to deliver mRNA vaccines while limiting unwanted inflammation.

More than one-quarter of young adults in Britain now say their gym memberships matter more to them than vacations or eating out.

Human neural stem cells that help form the brain and spinal cord are highly susceptible to SARS-CoV-2, including omicron variants BA.1 and BA.2, according to new research from the University of California, Riverside. The findings raise concerns about the potential effects of maternal COVID-19 infection on early nervous system development and underscore the importance of monitoring children exposed to the virus before birth.

Someone taking a weight-loss drug might leave half their dinner because they feel comfortably full. They might also stop because they feel nauseous. Measuring the leftovers would reveal the same result, but tell researchers little about why the person stopped eating.

A new study has characterized the “average” human genome, providing key information on normal human genetic variation and genetic disease risk. The researchers conclude that everyone—regardless of their current health status—could potentially be told they are at risk for numerous conditions based on their genetics alone.

A study led by the University of Malaga has shown that Ebola outbreaks do not occur randomly over time; rather, their occurrence is linked to specific large-scale meteorological patterns, including oscillations in regions thousands of miles away from Central Africa, where an epidemic of this potentially fatal disease is underway.

Researchers from the University of California San Diego have found that adding emotion management skills to family-based behavioral weight management may help adolescents maintain weight loss after treatment ends.

A new study of more than 1 million births led by McMaster University researchers has found that gaining too much weight during pregnancy, regardless of a person’s starting weight, is linked to a higher risk of life-threatening maternal complications.

The study of biological aging, how our cells, tissues and organs change over time, independent of how many years have passed, is a growing area of research that aims to help scientists understand the root causes of chronic illnesses and find ways to enhance longevity. A review article published in Trends in Endocrinology & Metabolism discusses the connections between pregnancy and biological aging.

Scientists at the University of Pittsburgh uncovered the unstable immune cells that can cause up to 40% of immunotherapy patients to experience serious side effects and showed that diet and microbiome composition influence the side effect’s severity.

Beginning survivorship care for head and neck cancer patients earlier is linked to better survival and lower recurrence, according to a new University of Pittsburgh study published in JAMA Otolaryngology–Head & Neck Surgery.

Fitting a hormonal intrauterine device (IUD) during surgery to help manage heavy menstrual bleeding reduces a woman’s risk of needing a hysterectomy in the following two years by more than half, according to a new open-label randomized controlled trial published in The Lancet.

For older adults with dementia or Parkinson’s disease, staying hydrated can be more complicated than simply drinking more water.

The results of numerous high-impact Phase III clinical trials that could affect kidney-related medical care were presented in person at American Society of Nephrology Kidney Week 2026, Oct. 22–25.

Devices that link human minds to computers are progressing rapidly. Already, these brain-computer interfaces (BCIs) are allowing patients with severe paralysis to communicate, use digital devices or control smart homes with their brains.

A free, online program developed by University of Colorado Boulder researchers has been shown to reduce the risk of depression relapse by double digits among new moms and moms-to-be who have struggled with it before.

Young adult cancer survivors face gaps in follow-up care caused by factors including geographic mobility and insurance changes, according to an analysis by UTHealth Houston researchers. While most young adults are navigating college, the workforce or relationships, survivors face that and more as they learn to manage their long-term health.

New research from Advocate Health’s Advocate Aurora Research Institute suggests that giving pediatric residents hands-on training with medical devices may help them communicate more effectively with the families of children frequently hospitalized in pediatric units.

In neurodegenerative disorders, including Alzheimer’s disease and progressive supranuclear palsy, abnormal accumulation of tau protein occurs in the brain. Identifying the location and extent of tau accumulation in vivo is crucial for understanding disease mechanisms and progression.
