It's no secret that the more we use antibiotics, the greater the chances that bacteria will develop a resistance to them. A new antibacterial wound dressing is designed to get around that problem, by using proteins instead of regular antibiotics.

Researchers in Canada have made a significant discovery relating to pancreatic cancer, pinpointing a protein that the cancer cells rely on for growth, and demonstrating how targeting them can inhibit tumor growth in the lab.

Aging comes for us all – but perhaps the unpleasant symptoms don’t have to. In a new study, scientists have found a kind of anti-aging immunotherapy, reinvigorating immune cells to better clear out defunct cells that contribute to the aging process.

Microneedle patches already show a great deal of promise as a painless alternative to hypodermic needles. A new one, however, could find use as a more effective means of treating serious bacterial infections of the skin.

Researchers in Israel have demonstrated a creative potential solution to the rise of superbugs with a set of "molecular tweezers" that can pick apart the protective film of bacteria, freeing the way for the human immune system to go to work.

The skin is the body’s first line of defense against infection, and new research has brought us closer to understanding how it works. Researchers at Yale have identified how immune cells spread themselves out to maintain the most effective patrol.

Researchers in the UK have developed a new type of glowing probe that increases its fluorescence in the presence of an enzyme linked to plaque buildup in the arteries, possibly acting as an early warning sign for cardiovascular disease.

An imaging technique has been developed offering detailed 3D videos of a human brain. The technique offers novel perspectives on the motions of a brain, delivering clinicians a new diagnostic tool and researchers insights into neurological disorders.

By turning modern scientific tools on an antibiotic discovered 70 years ago, researchers have unearthed a previously unknown mechanism it uses to pierce and pop superbugs like balloons, raising new hopes in the fight against drug-resistant bacteria.

Researchers at Indiana University have linked a protein secreted by the stomach to obesity. In tests in mice, the team switched off the protein and found that it reduced the animals’ body fat levels, even when fed a high-fat diet.

A very small pilot study has found several treatments of low-dose radiation, delivered from a CT scanner, could increase alertness and responsiveness in people suffering severe late-stage Alzheimer’s disease. However, the research is still preliminary.

While neural implants play a vital role in monitoring or stimulating parts of the brain, they're often attacked by the body's immune system. A new device gets around that problem by being very soft – and it's implanted using a needle made of sugar.
