Scientists are harnessing the cosmos as a scientific “instrument” in their quest to determine the makeup of the universe. Long ago Einstein recognized the potential existence of gravitational lensing, a consequence of his theory of general relativity. According to general relativity, celestial objects create dimples in space-time that bend the light traveling from behind.

Scientists have managed to program clones that imitate the actions of humans playing soccer (known as football in the U.K.) on a computer. The clones learn the players’ behavior and apply this knowledge in order to avoid their opponents and score goals.

High summer temperatures, pushed higher by global climate change, may bring with them a spike in hospitalizations for respiratory problems, according to an analysis of data from twelve European cities, from Dublin to Valencia. The data comes from a three-year collaboration between epidemiologists, meteorologists and experts in public health collaboration that investigated the short-term effects [...]

Wash away your gray? Maybe. Scientists have now solved a mystery that has perplexed humans throughout the ages: why we turn gray. These researchers show that going gray is caused by a massive build up of hydrogen peroxide due to wear and tear of our hair follicles. The peroxide winds up blocking the normal synthesis [...]

Human stem cells are used to create motor neurons that carry familial ALS mutations. These human stem cell-derived neurons look and act like normal motor neurons, and, when carrying ALS mutations, the cells undergo changes similar to those seen in ALS. This study presents a new human-derived cell system to use in studying ALS and [...]
