Many scientists assume people have sex for simple and straightforward reasons such as to experience sexual pleasure or to reproduce, but new research at The University of Texas at Austin reveals hundreds of varied and complex motivations that range from the spiritual to the vengeful.

A special type of cell found in the eye has been found to be very important in regenerating the retina in zebrafish and restoring vision even after extensive damage. Now, a UK team of scientists believe they may be able to use these cells – known as Müller glial cells – to regenerate damaged retina in humans.

Regular exercise and little or no caffeine has become a popular lifestyle choice for many Americans. But a new Rutgers study has found that it may not be the best formula for preventing sun-induced skin damage that could lead to cancer. Low to moderate amounts of caffeine, in fact, along with exercise can be good for your health.

Inspired by the efficient swimming motion of the bluegill sunfish, MIT researchers are building a mechanical fin that could one day propel robotic submarines.

Two graduate students at MIT’s School of Architecture and Planning want to harvest the energy of human movement in urban settings, like commuters in a train station or fans at a concert. The so-called “Crowd Farm” would turn the mechanical energy of people walking or jumping into a source of electricity.

Scientists at the U.S. Department of Energy have identified a new technique for cleansing contaminated water and potentially purifying hydrogen for use in fuel cells, thanks to the discovery of a innovative type of porous material.

An international team of astronomers using NASA’s Swift satellite and the Japanese/U.S. Suzaku X-ray observatory has discovered a new class of active galactic nuclei (AGN).

Allergies, like the common cold and asthma, have basically defied the best efforts of modern medicine to cure them. Now, a doctoral candidate at the Hebrew University of Jerusalem School of Pharmacy has come up with a new approach that offers hope for getting rid of them.
