Through experiments on roundworms and human cells in the lab, scientists have found a potential new pathway for the treatment of cancer that involves a naturally occurring fatty acid and a recently discovered form of programmed cell death.

The CRISPR-Cas9 gene editing system is an extremely powerful tool, but off-target edits can have serious consequences. Now, researchers have found a mutation of the CRISPR enzyme that’s almost 100 times more precise than the most commonly used one.

One of the problems with implants such as pacemakers is the fact that when their batteries run out, they have to be surgically replaced. It may someday be possible, though, to recharge those batteries by shining light through the patient's skin.

Impressive new work has demonstrated a potential way to restore vision in those suffering from degenerative diseases of the retina. A single injection of nanoparticles was found to create a working artificial retina, restoring vision to blind rats.

A new study out of Pennsylvania State University has offered up an exciting possibility in cancer treatment, demonstrating how a newly developed nanoparticle can target specific tumor tissue after being activated by light.

Ideally, we protect the body from radiation damage before it reaches us with shielding materials. Researchers have now developed a new nanocrystal treatment that could prevent some of the tissue damage radiation causes.

One of the many deteriorative effects of aging in humans is a decline in immune system function. But scientists may have uncovered a way to reverse this trend by transplanting a type of white blood cell from the young into the old.

New research is offering the first clinical trial insights into microdosing THC to treat chronic pain. The results of the small trial suggest tiny doses of THC may confer clinically apparent reductions in pain without inducing psychoactive effects.

Fireworks are a surefire way to create a spectacle of color and light, but research has revealed these dazzling displays could pose a health risk by releasing a range of harmful toxins that can linger in the air once the lights go out.

Scientists at the University of Exeter have developed a promising technique that could help slow the rise of antibiotic-resistant superbugs, by quickly illuminating bacteria when antibiotics are having the desired effect.

A new pilot study has demonstrated nitrous oxide, commonly known as laughing gas, may help military veterans suffering from PTSD. A larger trial is now underway after several studies demonstrated potential new uses for the gas.

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.
