Frequent cannabis users show no driving impairment after two-day break

On Sept. 10, 2025, a federal judge blocked the Department of Justice's attempt to subpoena medical records and other private health information on minors receiving hormone therapy and other gender affirming care at Boston Children's Hospital.

People are exposed to millions of fungal spores every day, even potentially harmful ones like those from Aspergillus fumigatus. For most individuals, this constant exposure is harmless, as the immune system efficiently clears the spores without causing illness.

Recent research, published in Biological Psychiatry, provides the first proof that evidence-based parenting programs are accompanied by specific changes in children's brain activity and decision‑making processes, and underscores the value of offering such programs early in life.

Researchers from King's have identified a new way to treat certain blood cancers using existing drugs, by turning a once-dismissed part of our DNA into a therapeutic target.

In October 2023, an unthinkable tragedy unfolded in Coleman, Wisconsin: An 8‑month‑old girl lost her life when a driver, impaired by cannabis, ran a stop sign and crashed into another vehicle. In February 2025, the driver pleaded guilty to negligent vehicular homicide and drugged driving with a minor passenger—and now faces up to 10 years behind bars.

Whether you're at a party, a family gathering or even at work, chances are you've heard someone say, "I'm on the (insert name) diet. It's amazing!" Or maybe you've been the one to say it. Either way, it's not surprising.

They're tiny particles—with potentially huge human consequences. Researchers from Aarhus University have identified a defect in the production of so-called exosomes in cells, associated with a mutation seen in dementia patients. This could lead to a better understanding of the development—and perhaps even a treatment—of Alzheimer's.

When doctors prescribe oxybutynin, it's usually for an unglamorous problem: bladder incontinence. But researchers have discovered a surprising new role for this decades-old drug—one that could open the door to treatments for a devastating class of genetic illnesses known as mitochondrial diseases.

Improved pay for NHS staff is important to prevent high numbers leaving the service, according to new data from UCL and University of Leicester researchers.

Mitochondria act as energy factories in cells and have their own, separate DNA. Mutations to mitochondrial DNA (mtDNA) have been observed in cancer, but it has been unclear how these changes might affect cancer growth.

Researchers from Keele University have revealed that retired Olympic athletes are more likely to develop skin cancer and osteoarthritis than the general population.

A study published in The New England Journal of Medicine finds that individuals who received medication for opioid use disorder (MOUD) while incarcerated were significantly more likely to continue treatment six months after release than those who did not receive MOUD.

Researchers at the University of Oulu's Research Unit of Clinical Medicine and Oulu Business School have examined how symptoms of adolescent ADHD (attention-deficit/hyperactivity disorder) and oppositional defiant disorder (ODD) are related to adult income.

The concept of the midlife crisis is part of the common lexicon. But did you know it was thought to occur at around age 35?

While vaccines can be very effective for preventing viruses, like the influenza A virus (IAV), they are often strain-specific and prone to viral escape mutations. IAV alone is responsible for around 500,000 deaths worldwide each year. To better serve vulnerable populations and prevent pandemic conditions, scientists have been searching for ways to create better, more universal, mutation-resistant, off-the-shelf IAV therapeutics.

You're introduced to someone and your attention catches on their eyes. They might be a rich, earthy brown, a pale blue, or the rare green that shifts with every flicker of light. Eyes have a way of holding us, of sparking recognition or curiosity before a single word is spoken. They are often the first thing we notice about someone, and sometimes the feature we remember most.

Rapid scientific advances are accelerating the development of medical innovations, from personalized treatments to curative gene therapies and advanced diagnostic tools. But significant policy and regulatory reforms at the Food and Drug Administration are needed to fully harness the game-changing potential of these technologies, according to a new white paper from the USC Schaeffer Center for Health Policy & Economics.

A study from The University of Texas at San Antonio Health Science Center indicates that changes in the body that lead to type 2 diabetes occur long before current diagnostic thresholds for prediabetes are met.
