Spanning nearly 100 laboratories in 45 countries, a landmark study has, for the first time, shown an association between genetic brain shape and size and the prevalence of neurological conditions such as Parkinson's disease and ADHD.

Toxic “forever chemicals” are a major environmental problem, and a growing body of research shows they’re also a major health problem. A new study has found people with higher levels of PFAS in their blood have poorer sleep.

A laser-led device that shoots light into the brain to test blood flow and volume can offer instant feedback on a patient's stroke risk and and provide a portable, affordable and non-invasive way for clinicians to make life-saving interventions.

Who’s funnier, AI or humans? A new study found that we find ChatGPT-generated comedy funnier than, or as funny as, comedy written by humans, including professional writers. The findings suggest that AI is no laughing matter for the entertainment industry.

Eating junk food during the crucial years of brain development impairs memory into adulthood, even when reverting to a healthy diet, new research has found. The impairment is caused by reduction in a neurotransmitter linked to Alzheimer’s disease.

Researchers have identified two genetic markers that may explain the link between eating red and processed meat and bowel cancer. Understanding the disease process and the genes underlying it can help develop better prevention strategies.

Hospital patients often pick up dangerous, hard to treat infections. An experimental vaccine given on arrival to hospital could protect against a range of drug-resistant bacteria and fungi, by activating a different arm of the immune system.

Researchers have uncovered the mechanism by which our taste buds detect ammonium chloride, exemplified by the distinct taste of salty licorice. They say the discovery provides evidence for the existence of a sixth basic taste.

A phase 2 clinical trial is currently exploring a new technique to slow the progression of type 2 diabetes. The simple outpatient surgery can be conducted in the early stages of diagnosis and delay the need for insulin shots.

ALS is a debilitating neurodegenerative disease with poor outcomes, but a pair of new studies may point towards a more optimistic future. In tests in human cells and live mice, scientists identified promising new targets for potential treatment.

A study has shed important light on migraine development by leveraging cutting-edge imaging technology to gain a new perspective on structures in the brain, which revealed enlarged spaces around the blood vessels in people suffering the condition.

Researchers working with a remote population in the Amazon have found the group experiences extraordinarily low rates of dementia. The study follows on from prior findings that the same group displayed almost no cases of age-related heart disease.
