Antioxidant supplements may not help ward off dementia, despite earlier research suggesting the contrary.

New research offers hope by showing how we might prevent prions from aggregating or growing into deadly diseases. The results also show that an antihistamine, astemizole, proved effective in reducing prion aggregation.

Researchers have discovered a method that appears to provide earlier warning of organ transplant rejection compared to standard methods, and requires only a blood test rather than a more invasive and painful needle biops...

Researchers have identified a signaling molecule key to the formation of scar tissue surrounding implantable medical devices, a process called fibrosis. Blocking this molecule prevents scar tissue from forming and could ...

Researchers have developed a cheap, portable camera that can photograph the retina without the need for pupil-dilating eye drops.

Microbes have evolved over millions of years to live in and on all parts of the human body. Scientists have created new ways to reconstruct how this evolution unfolded, using mathematical tools originally developed for g...

For roughly one-third of people diagnosed with bipolar disorder, lithium is a miracle drug, effectively treating both their mania and depression. Now a new develop tool has been developed to gauge success of preferred tr...

Using a technique that avoids the use of high-dose chemotherapy and radiation in preparation for a stem cell transplant, physicians have documented the first cure of an adult patient with congenital dyserythropoietic ane...

Add rapid, mobile testing for Zika and other viruses to the list of things that smartphone technology is making possible. Researchers have developed a smartphone-controlled, battery-operated diagnostic device that weighs...

Combining single-cell genomics and computational techniques medical researchers have defined cell-type composition of cancerous cells from 11 colorectal tumors, as well as adjacent noncancerous cells, a key to more targe...

Antioxidant supplements vitamin E and selenium -- taken alone or in combination -- did not prevent dementia in asymptomatic older men, according to a new study.

Using 5alpha-reductase inhibitors (5ARIs) is not associated with increased suicide risk in older men, but risks for self-harm and depression were increased during the 18 months after medication initiation, although 'the ...

More than half of older adults have some form of hearing loss, impacting everyday life and significantly affecting their health and safety if left untreated. Hearing aids are the most common treatment for hearing loss; h...

Researchers have developed a new way of visualizing the distribution of cholesterol in cells and tissues. Their research provides insights into the movement of cholesterol into and out of cells and could eventually ident...

So far, 53 Americans have been infected with Candida auris, which can cause organ failure. It is resistant to all three major classes of antifungal drug

Scientists identify two signaling proteins in cancer cells that make them resistant to chemotherapy, and show that blocking the proteins along with chemotherapy eliminate human leukemia in mouse models. Researchers sugge...

Physician researchers suspect that some cases of coronary artery spasm go unrecognized and are incorrectly treated with stents. The good news - there could be a simple fix to eliminate these unnecessary stenting procedur...

Genetic mutations that cause cancer also weaken cancer cells, allowing researchers to develop drugs that will selectively kill them. This is called "synthetic lethality" because the drug is only lethal to mutated (synthe...

Three-quarters of all breast cancer tumors are driven by the hormone estrogen. These tumors are frequently treated with drugs to suppress estrogen receptor activity, but unfortunately, at least half of patients do not re...

New genes which help prevent prostate, skin and breast cancer development in mice have been discovered by researchers. The study identified genes that cooperate with the well-known tumor suppressor gene PTEN, and showed ...

Take a peek at a satellite's view of spring in Earth's Northern Hemisphere.

Like a potter shaping clay as it spins on a wheel, physicists use magnetic fields and powerful particle beams to control and shape the plasma as it twists and turns through a fusion device. Now a physicist has created a ...
