As patients in desperate need of a liver transplant lay waiting, many livers that might give them a new life go unused by centers across America, according to new research.

Material can be used to treat damaged blood vessels or to make medical devices with intrinsic healing properties, which could reduce tissue scarring, report researchers.

Removal of a gene protected mice against arterial disease, and they stayed lean even when they ate more. The phenomenon underlying this beneficial phenotype is more active brown adipose tissue, a new study has found.

A staggering 73% of young adults surveyed said they would put off going to the hospital, but would wait to see if they felt better.

Recent synchrotron advances and the development of dynamic compression platforms have created the ability to investigate extreme states of matter on short timescales at X-ray beamlines using shock waves generated by impa...

A throwdown between a rapper and an astrophysicist centers on whether the Earth is a sphere, a scientific question that was supposedly settled in the third century B.C. Here's how we know it's a sphere.
