The effects of COVID and a new treatment for it are leaving a bad taste in the mouth for many. How do we detect what’s salty, sweet, bitter, sour or umami?

A few years after the 1918 Spanish Flu pandemic doctors around the world began to notice an increase in new Parkinson’s disease cases. This link between viral infection and increased Parkinson’s risk has been an ongoing mystery to scientists for well over a century. And the association isn’t just…

Health Canada on Thursday lifted restrictions on gay men donating blood, a move Prime Minister Justin Trudeau said was “good news for all Canadians" but had taken too long. Trudeau said at a news conference the ban should have ended 10 to 15 years ago, but research proving it would not affect the safety of the blood supply had not been done by previous governments.

A new method developed at the University of Copenhagen has been used to identify more than 1,000 bactericidal viruses in the human intestines. The researchers believe the discovery may help fight antibiotic resistance.

Researchers have created the most comprehensive healthy human cell atlas to date, tracking the placements of over a million cells across 33 organs in a vast joint effort.

Scientists are studying whether long COVID could be linked to viral fragments found in the body months after initial infection

Indonesia announced three deaths this week that health officials suspect are linked to a liver disease hospitalizing hundreds of children worldwide.

The 57-year-old patient who survived two months after undergoing a landmark pig heart transplant died of a pig virus, his transplant surgeon announced last month. In January, David Bennett, a handyman who suffered from heart failure, underwent a highly experimental surgery at the University of Maryland medical center in which doctors transplanted a genetically modified pig’s heart into him.

A new study published in Frontiers in Aging found that a combination of high-dose vitamin D, omega-3s, and a simple home strength exercise program (SHEP) showed a cumulative reduction by 61% in cancer risk in healthy adults aged 70 or older. It is the first study to test the combined benefit of three affordable public health interventions for the prevention of invasive cancers. Following future studies, the results may impact the future of cancer prevention in older adults.

Antidepressants are the mainstay for treating depression, but their use is clouded by questions about lasting efficacy. A new study now suggests antidepressants may not improve people's quality of life in the long run, compared to depressed people w

Researchers from a USC-led consortium have discovered 15 “hot spots” in the genome that either speed up brain aging or slow it down — a finding that could provide new drug targets to resist developmental delays, Alzheimer’s disease and other degenerative brain disorders.

Researchers have long been looking for treatment options for Parkinson's disease from drug-producing bacteria to neuron treatments. Despite all advances, however, the disease remains prevalent with absolutely debilitating effects eroding motor functions and often confining patients to a bed or wheelchair.

Remote robotic-assisted surgery is far from new, with various educational and research institutions developing machines doctors can control from other locations over the years. There hasn't been a lot of movement on that front when it comes to endovascular treatments for stroke patients, which is why a team of MIT engineers has been developing a telerobotic system surgeons can use over the past few years. The team, which has published its paper in Science Robotics, has now presented a robotic arm that doctors can control remotely using a modified joystick to treat stroke patients.

In a small trial, immune cells that fight the Epstein-Barr virus have stopped the progression of multiple sclerosis, an autoimmune condition that can lead to symptoms, such as difficulty walking, that worsen over time...

In 1928, Scottish microbiologist Alexander Fleming discovered what we know today as penicillin. Fleming’s work and that of his successors would go on to forever change how we treat bacterial infections. And to this day, antibiotics are one of the most powerful tools we have to protect people from a host of harmful bacteria.

On a screen at the American Association of Cancer Research (AACR) conference here on Saturday, one of Jinming Gao’s graduate students squirted an acid into a test tube in their lab at the University of Texas Southwestern Medical Center. Almost immediately, fluid at the end of the tube began to glow as a white star under infrared light, visible on a surgical monitor. When the student squirted it with a base, the light winked out.

Scientists have developed a blood test that can predict whether someone is at high risk of a heart attack, stroke, heart failure or dying from one of these conditions within the next four years. The test, which relies of measurements of proteins in the blood, has roughly twice the accuracy of existing risk scores. It could enable doctors to determine whether patients’ existing medications are working or whether they need additional drugs to reduce their risk.

When dieting and exercise aren’t enough, weight-loss surgery can be an effective obesity treatment. But people who don’t want surgery have other options, including insertion of an appetite-suppressing balloon or other implant in the stomach. Now, researchers report in ACS Applied Materials & Interfaces that they have augmented that procedure in laboratory animals by coating an implant with a laser-activated dye that kills cells producing ghrelin, the “hunger hormone.”
