Hinting at a future alternative to opioid painkillers, scientists have developed a tiny implant designed to ease post-surgery pain and then dissolve once the job is done.

So far, the research has been limited to lab animals, and it will be several years before the technology could be ready for human testing....

When breast cancer patients sleep, tumor cells may "awaken" and spread through the bloodstream, a surprising study out of Switzerland reveals.

Circulating cancer cells that later form new growths (metastases) do not arise continuously as previously assumed, according to researchers at ETH Zurich, the University Hospital Basel and the University of Basel.

"When the affected person is...

An experimental Alzheimer's drug called crenezumab did not prevent or slow mental decline in patients with a genetic mutation that greatly raises the risk of developing the disease, the results of a decade-long clinical trial show.

The mutation seen in the few hundred study participants from an extended famil...

Cancer clinical trials in the United States appear to be rebounding after a significant slowdown during the pandemic, researchers say.

For the study, the investigators analyzed data from the Dana-Farber Cancer Institute in Boston and the Tisch Cancer Institute at Mount Sinai Medical School in New Y...

An experimental drug for the neurological disorder ALS was approved in Canada on Monday, but an ongoing evaluation of the treatment by the U.S. Food and Drug Administration has raised questions about its effectiveness.

A condition of Hea...

In what could turn out to be a potential breakthrough in the treatment of pancreatic cancer, a new report suggests a key component of a patient's immune system can be rewired to assassinate tumor cells.

The experimental approach has already shown promise in one patient.

Kathy Wilkes, 71, had been stru...

A genetically engineered tomato could one day rival salmon as a dietary source of vitamin D, if early research pans out.

British scientists used gene "editing" to produce the tomato, which is chock full of provitamin D3, a precursor that the body can convert into vitamin D.

The gene twe...

With the United States facing an epidemic of drug overdoses, researchers are developing a wearable patch that can detect an oncoming opioid OD and deliver doses of a drug that could save lives.

The Indiana University Bloomington research team has received a three-year, $3.8 million grant from the U.S. National Institute on Drug Abuse to develop the patch, which combines two separate cutti...

Dogs' ultra-sensitive noses can detect illegal drugs and even cancer, and a new study suggests they may also be able to sniff out COVID-19 in airline passengers.

Not only that, these trained canines can do so with an accuracy comparable to a PCR nose and throat swab test, the researchers noted.

"Our preliminary observations suggest that dogs primed with one virus type can in a few h...

An international research effort has unveiled the most extensive reference map yet of individual cells within the human body, knowledge that could revolutionize the study of health and disease.

The massive Human Cell Atlas contains detailed maps of more than one million individual cells across 33 organs and systems, researchers announced this week.

"You can think of it as a Google M...

Does science sell? Sometimes.

Using science to sell chocolate chip cookies and other yummy products is likely to backfire, a new study shows, but touting scientific research behind more practical, everyday items -- such as body wash -- can be an effective marketing strategy.

"People see science as cold, but competent. That doesn't pair well with products designed to be warm and plea...

An experimental COVID-19 vaccine in pill form could be a win-win, as it not only protects against infection but also limits the airborne spread of the virus, tests in lab animals show.

The current vaccines reduce the risk of serious COVID-19 illness and hospitalization but aren't foolproof armor against infection with

The most common treatments for sleep apnea are mechanical -- CPAP machines, mouthguards and the like.

But researchers think they've found a drug that might ease sleep apnea in some.

The drug sulthiame, normally used to treat epilepsy, appeared to reduce breathing pauses by more than 20 events an hour, on average, in
