Scientists continue to illuminate the many ways exercise can positively influence brain health by examining its effects on the many forms of cognitive function, and the latest places a spotlight on our ability to recall past experiences.

Giving elderly mice blood transfusions from younger mice can reverse some effects of aging. A new study identifies a specific component of young blood that improves muscle repair function lost with time, potentially opening new anti-aging therapies.

Sometimes, viruses can help us. According to a new study, a combination of antibiotics and a bacteria-killing virus eradicates harmful bacteria better than either one is capable of doing on its own.

In a major breakthrough for regenerative medicine, scientists have partially restored vision in a blind man using an emerging technique called optogenetics, which enabled the patient to locate and identify objects for the first time in decades.

In a promising new study, scientists have demonstrated how fecal transplants can alter the microbiome to make advanced melanoma sufferers, who have not responded to immunotherapy in the past, more responsive to these treatments.

A blood test that reveals the severity of brain injuries in hours through a key biomarker was recently approved for clinical use, but researchers are now setting their sights on a point-of-care solution that can deliver results within 15 minutes.

Liver cells are quick to regenerate, and now researchers have discovered just how persistent those cells can be. In tests in pigs with severe liver damage, functional new backup livers were found to grow in the animals’ lymph nodes.

We've already heard about various smartphone-linked devices that determine if the user is intoxicated. According to a new study, though, even a phone on its own can be used to measure a person's drunkenness.

Strokes can leave lifelong lingering issues, as neurons are damaged and die. But now, researchers at the University of Pittsburgh have identified a new drug that could help prevent damage even after a stroke, with tests in mice showing promise.

Imagine needing a liver transplant and, instead of waiting for a donor, a new one could just be grown from your own skin cells. In a big step towards this, mini human livers grown from stem cells have been successfully transplanted into rats.

Scientists have managed to copy one of cancer's strategies to hide from the immune system, and use it for good. They made new microparticles that permanently prevent transplanted tissue or even whole limbs from being rejected by the immune system.

Doctors are reporting a bizarre case of a woman who urinates alcohol. The woman showed none of the other regular signs of excessive alcohol consumption, leading them to conclude that yeast in her bladder was brewing the booze.
