Scientists have failed to show that weight-loss wonder drug semaglutide can also slow the progress of Alzheimer's disease (AD), as two two-year clinical trials end in disappointment for patients, medical scientists and drugmaker Novo Nordisk.

Scientists have discovered why males get dental disease more frequently and with greater severity than females, pinpointing the specific inflammation driving it. This could help treat gum and tooth decay in both sexes through different interventions.

Scientists have found the clearest evidence yet that Epstein-Barr virus – which nearly all of us carry for life – is directly responsible for hijacking our immune system's cells to cause lupus, a chronic disease that affects up to a million Americans.

A surprising trigger for hair regrowth may lie in the body’s fat cells. Researchers have shown that mild skin irritation can trigger fat cells to go into panic mode, sending signals to dormant follicles that can fuel new hair growth within weeks.

There's growing evidence that a Mediterranean diet can provide relief from symptoms of irritable bowel syndrome, offering people more variety, nutrients and easier adherence than the current restrictive frontline approach to manage the condition.

A new study offers hope for brain cancer patients facing memory loss from radiotherapy. By blocking a single immune receptor, scientists preserved cognition in mice without dulling the cancer-killing power of radiation.

When breathing becomes a daily battle, even the simplest acts can feel exhausting. Now, a new study has found the key to easing chronic breathlessness caused by lung disease: singing.

Friendships, community ties and family bonds may apply the brakes to cell aging, providing a simple way to invest in health in older age. In a new study, scientists find that social connections are tied to slower biological aging and less inflammation.

A once-daily pill for ulcerative colitis has delivered strong results in a clinical trial, easing symptoms even in patients for whom other treatments had failed and raising hopes for a safer, more effective therapy for a condition that affects millions.

A natural psychedelic may do more than alter perception. A new study found that at sub-hallucinogenic doses, DMT shielded the brain from stroke damage in animal models, reducing inflammation, preserving the blood-brain barrier, and speeding recovery.

Psoriasis may not have a cure, but significant relief might be found at the dinner table. A clinical trial has shown that the Mediterranean diet could dramatically improve symptoms, quality of life and overall health of those with the condition.

Switching off a single enzyme in immune cells protected mice from obesity, type 2 diabetes, and fatty liver disease in a new study, offering a potential new treatment target for metabolic disorders.
