Medicinal cannabis is most often prescribed for pain, anxiety and sleep—here's what the evidence says

Scientists have discovered how mutations in a specific gene drive the rare developmental disorder Weaver syndrome, which is marked by intellectual disability and overgrowth and predisposes people with the condition to cancer. Their work has additional relevance for a growing suite of related diseases and provides important insights that may one day lead to improved therapies.

UCLA scientists have developed the first comprehensive road map showing how the ovarian reserve forms in primates, providing crucial insights into women's health that could revolutionize treatments for infertility and hormonal disorders such as polycystic ovary syndrome, or PCOS.

People with type 2 obesity-driven diabetes tend to have more aggressive breast cancers, but no one knows exactly why. A new study by researchers at Boston University Chobanian & Avedisian School of Medicine and published in Communications Biology found that tiny particles in the blood, known as exosomes, which are altered by diabetes, can reprogram immune cells inside tumors, making them weaker and allowing the cancer to grow and spread more easily.

When asked to choose between bad outcomes from lockdowns, most Americans said they'd rather risk more COVID deaths than allow more child abuse, domestic violence or deaths caused by economic hardship.

A newly published review from the Kennedy Krieger Institute highlights major progress in developing biomarkers to improve the diagnosis and treatment of Sturge-Weber syndrome (SWS).

People with schizophrenia are more likely to develop chronic obstructive pulmonary disease (COPD), suggesting a possible syndemic relationship between the two diseases, in addition to people not seeking appropriate medical care. A new article examining the link between COPD and schizophrenia was published in the July 2025 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation.

Older adults who are overweight may face a lower risk of death in the first 30 days following major elective surgery compared with those who have a normal body mass index (BMI), new research suggests.

A special set of neurons directs mice's attention to or away from their peers, depending on the situation. The Kobe University discovery has implications for finding causes for neuropsychiatric conditions such as autism spectrum disorder or schizophrenia.

Research scientists from the Indiana University School of Medicine and Regenstrief Institute have found that individuals with a parent who died from liver disease face more than double the risk of developing alcohol-associated hepatitis, one of the deadliest forms of alcohol-related liver disease, compared with similar heavy drinkers without that family history. The study is published in the journal Hepatology Communications.

Have you heard of a "cortisol cocktail?" Rather than something you might order at a bar, this drink is one of the latest wellness trends floating around social media.

If you're a woman approaching middle age and you're on social media, you might have been urged to get your hormones checked.

A pilot study led by CUNY SPH researchers found that relatively simple steps to improve ventilation in New York City nail salons may drastically reduce workers' exposure to harmful airborne chemicals.

A new review study by the Max Planck Institute for Human Development shows that nearly 1 in 3 people choose to avoid medical information about serious health conditions if they fear they may be affected. One of the main reasons driving this behavior is a lack of trust in the medical system. The study has been published in Annals of Behavioral Medicine.

The question of how far life expectancy will rise in the future is a highly controversial topic among scientists. From today's perspective, life expectancy rose at an almost dizzying rate at the beginning of the 20th century. People born in 1900 lived to an average age of 62, whereas those born in 1938 lived to around 80.

In a recent clash against the Melbourne Storm, the Brisbane Broncos endured a nightmare rarely seen in professional sport—three players tore their hamstrings in a single game. Two players, Adam Reynolds and Ezra Mam, went down in the same play.

QUT researchers have created a powerful new tool that could predict when an athlete is at risk of suffering another injury when returning to play from a previous injury.

Researchers have developed a new light technology that appears to improve cognitive function in Alzheimer's patients in clinical trials. The hope is that the idea can be developed into ordinary lamps that people can install to prevent the disease.

New research from the University of South Australia shows that ibuprofen and acetaminophen are quietly fueling one of the world's biggest health threats: antibiotic resistance.
