Efforts to suppress or change gender identity prove ineffective and harmful, Australian research indicates

Genetic inheritance may sound straightforward: One gene causes one trait or a specific illness. When doctors use genetics, it's usually to try to identify a disease-causing gene to help guide diagnosis and treatment. But for most health conditions, the genetics is far more complicated than how clinicians are currently looking at it in diagnosis, counseling and treatment.

About 1,500 federally-funded health centers that serve millions of low-income people face significant financial challenges, their leaders say, as the government shutdown compounds other cuts to their revenue.

Hormonal changes during menopause can drive suicidal thoughts—a crisis that health care services have failed to recognize or adequately address. The devastating link is laid bare in research my colleagues and I conducted recently.

Restless nights can take a toll that goes beyond next-day tiredness. Sleep influences nearly every aspect of our health, and chronic disruptions to sleep patterns have been linked to increased risks for different diseases. To further investigate this connection, a recent study published in Cureus explored the association between sleep-related leg movements and diabetes.

The American Cancer Society has released a report on occurrence and outcomes in the United States for this subtype of breast cancer. Findings show an estimated 33,600 women will be diagnosed with lobular breast cancer or invasive lobular carcinoma (ILC) this year.

What if a protein could be injected to help heal both "leaky gut" and severe depression? New research from the University of Victoria (UVic), published in Chronic Stress, shows that a glycoprotein called reelin may one day be able to do just that.

Important genetic differences in how females and males experience depression have been revealed for the first time in findings that could pave the way for more targeted intervention and treatments.

Rotavirus causes severe dehydrating diarrhea in infants and young children, contributing to more than 128,500 deaths per year globally despite widespread vaccination efforts. Although rotavirus is more prevalent in developing countries, declining vaccination uptake in the United States has resulted in increasing cases in recent years.

Researchers led by Aurore Perrault at Concordia University, Canada and Valeria Kebets at McGill University, Canada, have used a complex data-driven analysis to uncover relationships among multiple aspects of sleep and individual variation in health, cognition, and lifestyle.

For patients with vestibular schwannoma (VS), those with anxiety have more severe dizziness, according to a study published online Oct. 2 in JAMA Otolaryngology-Head & Neck Surgery.

A new treatment for a debilitating inflammatory condition which affects joints and skin has shown promising early results in an international clinical trial of more than 200 patients worldwide.

A pilot study published in the Journal of the American Geriatrics Society found that a prehabilitation program that combines physical therapy, nutrition, and mindset support in the weeks leading up to major elective surgery is feasible and has the potential to improve postoperative outcomes.

To better understand anxiety, a psychologist from the University of Kansas studied 90 teenage girls in sessions spanning three years, using wearable eye‐tracking glasses as the subjects gave a speech to two judges: one who responded positively and one who responded potentially negatively. In other words, one judge maintained a neutral facial expression, occasionally looked around the room, and shifted in their seat.

In lieu of animal experiments, researchers from the University of Rochester are using state-of-the-art microchips with human tissue to better understand how the brain operates under healthy conditions and is damaged through neurodegenerative diseases or conditions like sepsis.

Cognitive decline and anxiety in Parkinson's disease are often only recognized at a late stage, yet they can greatly impact people's lives. Research by Marit Ruitenberg focuses on new tests and methods to improve early identification of these symptoms.

More than three-quarters of U.S. counties and jurisdictions are experiencing declines in childhood vaccination rates, a trend that began in 2019, according to a September 2025 NBC News–Stanford University investigation. The report also found a "large swath" of the U.S. no longer has the "basic, ground-level immunity" needed to stop the spread of measles.

Voluntary medical male circumcision is one of the most important ways to reduce new HIV infections. The foreskin contains receptors that the HIV virus can attach to, and removing it reduces HIV transmission from women to men by about 60%.

Understanding the interaction between immune cells and cancer cells has important implications for cancer immunotherapies, including checkpoint inhibitor drugs and cell-based therapies, as well as newer treatments like cancer vaccines.
