Imagine if a doctor could look at your DNA and predict not just your disease risk, but also which foods you're drawn to – and whether those cravings are quietly protecting you.

A narrative review found that tight-fitting underwear may modestly raise scrotal temperature and is inconsistently linked to lower sperm production measures. However, current evidence does not show that switching to looser underwear improves real-world fertility outcomes.

New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London and published in The Lancet Psychiatry has found that people with psychosis experiencing Post Traumatic Stress Disorder (PTSD) can benefit from a Trauma-Focused therapy integrated with Cognitive Behavior Therapy for psychosis (CBTp).

Removing criminal penalties for possessing cannabis for personal use, or introducing tightly controlled legalisation of cannabis, does not appear to increase levels of cannabis use.

Researchers at Cedars-Sinai Health Sciences University and Johns Hopkins University have identified genetic mutations that may explain why some people develop a spontaneous cerebrospinal fluid (CSF) leak in the spine.

The bacteria enterotoxigenic E. coli and Shigella together cause hundreds of millions of infections each year and are among the leading causes of diarrheal death, especially in children.

Researchers at Niigata University's Brain Research Institute have uncovered a new function of amyloid precursor protein (APP), a molecule long studied as the precursor to amyloid-β (Aβ) in Alzheimer's disease (AD).

Hundreds of genes have been linked to autism, yet the precise molecular and cellular mechanisms behind it remain largely unclear.

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are widely prescribed for diabetes and obesity, but studies have found evidence that the medications may also influence behavior, such as supporting impulse control and reducing substance use and alcohol consumption by potentially interacting with the brain's reward and stress systems.

Newborn nerve cells must squeeze through crowded, narrow spaces-through dense tissue, past other cells, between fibers-to reach the areas where they form neural circuits in the brain cortex.

A vibrating pill could help doctors determine if a patient with anorexia nervosa may have a higher risk of relapse, according to a new study by UCLA Health.

Plague is commonly associated with rats, crowded medieval cities, and the epidemics that swept across Europe during and after the Middle Ages.

A new study from Michigan State University found increases in binge eating when taking hormone pills in the form of oral contraceptives - but not in all women.

Carnegie Mellon University and University of California, San Francisco researchers found that childhood trauma, poverty, social isolation and other adverse life experiences are associated with brain changes linked to schizophrenia-spectrum disorders - findings that could help researchers identify people at risk earlier and develop interventions before severe symptoms emerge.

Women who lift weights may have a lower risk of major heart disease, especially when combined with aerobic exercise, according to a new study published today in JACC, the flagship journal of the American College of Cardiology.

A fast-rising strep bacterium has become increasingly notorious for causing serious infections in humans, including complications that can lead to muscle damage and patient death. New Houston Methodist research appearing in The American Journal of Pathology, published by Elsevier, sheds light on how Streptococcus dysgalactiae subspecies equisimilis (SDSE) causes disease and may provide important insights to aid in vaccine development.

Cells have surface receptors that couple to proteins and other molecules to initiate or inhibit certain behaviors.

An orange-colored yeast species isolated from a Baltimore sidewalk several years ago could be the basis of eco-friendly mosquito traps that reduce malaria transmission, according to a new study from researchers at the Johns Hopkins Bloomberg School of Public Health.

A study assessed whether exposure to their own reflection influences the development of facial mimicry, a process associated with empathy and emotion recognition, in 4-month-old infants.

Researchers at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC analyzed brain imaging and clinical data from more than 17,000 participants across five major aging and Alzheimer's disease studies.
