More than one in three atrial fibrillation (AF) patients at intermediate to high risk for stroke are treated with aspirin alone, despite previous data showing this therapy to be inferior to blood thinners, new research s...

Researchers have conducted the first ancient DNA investigation of the Himalayan arc, generating genomic data for eight individuals ranging in time from the earliest known human settlements to the establishment of the Tib...

Scientists are getting closer to directly observing how and why water is essential to life as we know it.

Tumors are composed of many subpopulations of cells. Some of these subpopulations of cancer cells can be predicted and do not develop randomly as previously thought, report investigators.

The heart is the only muscle that contracts and relaxes continuously over a lifetime to pump oxygen-rich blood to the body's organs. Researchers now have identified a previously unrecognized enzyme that could optimize co...

Parents of young children diagnosed with autism spectrum disorder (ASD) may experience significant difficulties in discussing treatment options with the child's pediatrician, according to new research. Among the barriers...

Oxygen is important for the proper function of all human cells, but cancer cells thrive even when deprived of it. Now, researchers have identified a new signaling pathway that helps cancer cells cope with the lack of oxy...

DNA molecules don't just code our genetic instructions. They also have the unique ability to conduct electricity and self-assemble into well-defined shapes, making them potential candidates for building low-cost nanoelec...

The use of patient navigators -- individuals who assist patients in receiving health care services -- may improve comprehensive cancer screening rates among patient populations not likely to receive recommended screening...

Lychnopholide, a substance isolated from a Brazilian plant, and formulated as part of 'nanocapsules' cured more than half of a group of mice that had been infected experimentally with Chagas disease parasites.

A new study highlights the difficulty in defining and managing age-related testosterone decline in older men. To understand the accuracy of using signs and symptoms to predict low testosterone in older men, researchers c...
