Creatine is safe, effective and important for everyone, researcher says

Depression and bipolar disorder of late onset may represent more than just mental health conditions. Growing evidence suggests these late-life mood disorders (LLMDs) could be not merely risk factors, but rather early warning signs of neurodegenerative diseases like dementia, even when they appear years before memory loss or other cognitive symptoms become apparent.

A new study explains the genetic underpinnings of a rare and aggressive form of ovarian cancer—and offers a potential pathway for new treatments.

More young women in the United States are being diagnosed with breast cancer and several celebrities have helped raise awareness by sharing their stories.

As recommendations suggest extending hormone-based breast cancer treatment to 10 years for some patients, a new study sheds light on whether patients are opting for it.

The inaccuracy of race and ethnicity data found in electronic health records (EHRs) can negatively impact patient care as artificial intelligence (AI) is increasingly integrated into health care. Because hospitals and providers inconsistently collect such data and struggle to accurately classify individual patients, AI systems trained on these datasets can inherit and perpetuate racial bias.

Cancer cannot be understood as a single, uniform disease. The more we delve into studying each type of tumor, the more we recognize the need to subclassify the disease. This concept has led to what we now call precision oncology, characterizing the molecular features of a patient's specific cancer to determine the most effective treatment.

A new study from The University of Texas at Arlington details a novel strategy for how the body clears out dead cells during stress, revealing unexpected roles for well-known stress-response genes—a discovery that could help scientists better understand diseases affecting the immune system, brain and metabolism.

Scientists have discovered a link between bacteria in the mouth and gut and the progression of cognitive decline in Parkinson's disease. Specific changes in these bacteria, known as the microbiome, have been associated with cognitive decline in Parkinson's. This includes the shift from mild memory issues to dementia, a common and distressing symptom of the disease.

A compound found in the gut may reduce some of the manifestations of Alzheimer's disease, according to a Northwestern Medicine study published in the Journal of Clinical Investigation.

A new study from the University of Colorado Anschutz Medical Campus shows that primary care clinics can successfully help patients start using continuous glucose monitors (CGMs), which track blood sugar levels in real time.

A new study to be presented at the SLEEP 2025 annual meeting found that teens with earlier, more efficient, and less variable sleep patterns at age 15 had better cardiovascular health at age 22.

Guns are now the leading cause of death for youth in the United States. Researchers from Mass General Brigham investigated whether firearm mortality rates among U.S. children ages 0–17 changed in the 13 years following a 2010 Supreme Court ruling that applied the Second Amendment to state and local governments.

Stress worsens sleep quality and can impair memory. Shinjae Chung, from the University of Pennsylvania, led a study to explore a neural pathway in male mice that stress may influence, to cause sleep and memory disturbances.

A unique study purposely giving participants Streptococcus pyogenes (Strep A) to learn how much penicillin it takes to prevent infection has found the amount needed is much lower than previously thought—a discovery that will transform thinking on treatment for people living with rheumatic heart disease (RHD).

A study from the Hebrew University of Jerusalem, published this week in Proceedings of the National Academy of Sciences reveals a previously unknown peripheral mechanism by which paracetamol (also known as acetaminophen, Tylenol, or Panadol) relieves pain.

Stopping the widespread use of unnecessary, potentially even harmful, cancer screenings can take up to 13 years and potentially even longer after new guidelines are put in place, according to a new study published in BMJ Quality & Safety.

UC Davis infectious diseases experts George Thompson and Angel Desai are raising the alarm about the role new pesticides can play in building resistance to antifungal medical treatments. In a commentary in the New England Journal of Medicine, they call for a coordinated, global "One Health" approach to developing, testing and using agents to fight pathogens like fungi and bacteria.

Researchers from the University of California San Diego School of Medicine have discovered that children living with multiple sclerosis (MS) show signs of accelerated biological aging, even in their teenage years. The research, published online recently in Neurology, is the first to examine whether MS causes early aging in a pediatric population—offering new insight into the disease and its long-term progression.
