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.

When someone has suffered a major nerve injury, there are two common treatments: a nerve graft, or a conduit to guide the regrowth of the nerve. While both approaches have their drawbacks, a new variation on the latter may succeed where they fail.

Although it's crucial that people get vaccinated against tuberculosis, the vaccine isn't always very effective – at least, not when injected through the skin. New research, however, shows that it works much better when delivered directly into a vein.

Although titanium implants are strong and light, they're subject to colonization by harmful microbes. Infections of the surrounding tissue can result. Now, however, research suggests that electrifying the titanium may provide a solution.

​We've already heard about water-repellant materials that copy the structure of the lotus leaf. Now, however, scientists have created a flexible optical plastic that wards off liquids even better, and it was inspired by something else – the humble Enoki mushroom.
