One of cancer’s crafty tricks involves manipulating the host’s immune cells to protect tumors instead of fighting them. Now researchers at Massachusetts General Hospital have turned the tables again, transforming these cells back into cancer killers.

An experimental gene therapy developed to treat children born with a rare immunodeficiency disease has demonstrated extraordinary efficacy according to a new long-term follow-up study published in the New England Journal of Medicine.

Researchers have developed a new vaccine candidate for dengue virus, a notoriously tricky pathogen to deal with. The new candidate has a number of advantages over existing treatments, with tests on mice using microneedle patches proving promising.

Antibiotic-resistant bacteria, or “superbugs,” pose one of the most dangerous looming threats to public health. Now, researchers have found a new potential weakness in some of the worst strains, which makes them choke on their own toxic molecules.

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.
