A new type of cancer therapy that uses a common virus to infect and destroy harmful cells is showing big promise in early human trials, say UK scientists. One patient's cancer vanished, while others saw their tumours shrink. The drug is a weakened form of the cold sore virus - herpes simplex - that has been modified to kill tumours.

A new method to detect Parkinson’s disease has been determined by analysing sebum with mass spectrometry. The study, published today in the Journal of the American Chemical Society, have found that there are lipids of high molecular weight that are substantially more active in people suffering from Parkinson’s disease.

Solving a sleep mystery, Dr. Emmanuel Mignot of Stanford University helps pave the way for new treatments. The richest award in science is going to a Stanford sleep scientist and other top thinkers in their fields, named winners of the glitzy Breakthrough Prize on Thursday morning.

Five seriously ill lupus patients have seen their disease driven into remission after a single infusion of modified immune cells, in a small trial that borrows from cancer therapy to harness patients' own cells to treat the autoimmune condition.

Chemotherapy drugs can be lifesaving – but they don’t work for all patients or for all cancers. That’s why a team of researchers at the University of Toronto Mississauga is looking at new ways to use special types of light to target cancer cells resistant to current drug therapy – an approach that might be easier on some patients than traditional chemotherapy.

Tumor cells are notoriously good at evading the human immune system; they put up physical walls, wear disguises and handcuff the immune system with molecular tricks. Now, UC San Francisco researchers have developed a drug that overcomes some of these barriers, marking cancer cells for destruction by the immune system.

Medtronic placed a $2.6 million order for some of the company’s instruments and cameras, and its interest in Titan should help the smaller firm as it seeks to win approval for its device and market it globally.

Just about a million organ transplants have now been performed in the United States. The milestone was reached Friday, according to the United Network for Organ Sharing (UNOS), the nonprofit facilitator of these life-saving operations in the U.S. It’s been nearly 70 years since the first donated whole organ was successfully transplanted into a human.

The United States recorded its one millionth organ transplant Friday afternoon, a historic milestone for the medical procedure that has saved thousands of lives. The record achievement was confirmed at 12:50 p.m. ET by the United Network for Organ Sharing, a nonprofit that runs the only organ procurement and transplantation network in the country.

A malaria vaccine with "world-changing" potential has been developed by scientists at the University of Oxford. The team expect it to be rolled out next year after trials showed up to 80% protection against the deadly disease.

According to a new study, long-term use of prescription steroids lowers the volume of white matter in the brain, potentially impacting memory recall and other functions.

A 4 year-old-boy is recovering after a metal straw pierced an artery in his neck. The freak accident occurred when preschooler Charlie DeFraia fell from a porch ledge while sipping a yogurt drink through a metal straw at his family's home in East Moriches, New York, in June, according to Today.

The myriads of microbes in our gut, collectively termed the microbiome, are considered important to our health, but they can also harbor bacteria that contribute to inflammatory bowel disease or other disorders. Currently, however, it is impossible to target such disease-contributing bacteria without harming the surrounding beneficial microbes.

When you pop a pill, it begins a long and convoluted journey into your stomach, through the twisting intestines, and then into the bloodstream.

Monkeypox cases in some large U.S. cities appear to be declining, matching trends seen in Europe, and experts are cautiously optimistic the outbreak may have peaked in places hit hardest hit by the virus. The World Health Organization earlier on Thursday said monkeypox cases reported globally declined 21% last week, after a month-long trend of rising infections, but noted that U.S. cases continued to rise.

The use of biologics to treat atopic disease before and during pregnancy does not seem to negatively affect maternal or fetal outcomes, according to a review published in The Journal of Allergy and Clinical Immunology: In Practice.

Researchers at the University of British Columbia have discovered what they describe as a "weak spot" in all major variants of the virus that causes COVID-19 — a revelation they believe could open the door for treatments to fight current and future mutations.

For all the advances in medical technology humans have developed, there is one thing it hasn't been able to do: stop us from getting old. We've managed to extend the human lifetime dramatically in the last couple of centuries, greatly diminishing infant and child mortality and pushing back on disease with antibiotics and vaccines.

How did our medieval ancestors use dove faeces, fox lungs, salted owl or eel grease in medical treatments? A Wellcome funded project at Cambridge University Library is about to find out.

Sabra Klein is deeply aware that sex matters. During her PhD research at Johns Hopkins University, Klein learned how sex hormones can influence the brain and behavior. “I naively thought: Everybody knows hormones can affect lots of physiological processes—our metabolism, our heart, our bone density. It must be affecting the immune system,” she says.
