A novel strategy to treat a life-threatening irregular heart rhythm called ventricular tachycardia relies on noninvasive radiation therapy, which is typically directed at cancerous tumors. Noninvasive imaging techniques show irregular heart tissue mapped with the location of misfiring electrical signals, allowing doctors to direct radiation at the specific area of the heart triggering the problem.

The study, conducted using fruit fly populations bred to model natural variations in human sleep patterns, provides

With the discovery of an eighth planet, the Kepler-90 system is the first to tie with our solar system in number of planets. Artist’s concept.

RoboBees manufactured by the Harvard Microrobotics Lab have a 3 centimeter wingspan and weigh only 80 milligrams. Cornell engineers are developing new programming that will make them more autonomous and adaptable to complex environments.

Climate change Credit: © f9photos / Fotolia Approaching the second half of the century, the United States is likely to experience increases in the number of days with extreme heat, the frequency and duration of heat waves, and the length of the growing season. In response, it is anticipated that societal, agricultural and ecological needs

Do video games give gamers an edge in learning? Credit: © Hoda Bogdan / Fotolia Neuropsychologists of the Ruhr-Universität Bochum let video gamers compete against non-gamers in a learning competition. During the test, the video gamers performed significantly better and showed an increased brain activity in the brain areas that are relevant for learning. Prof

At its peak on Sept. 11, 2016, the ozone hole extended across an area nearly two and a half times the size of the continental United States. The purple and blue colors are areas with the least ozone.

While human-made devices inspired by gecko feet

This suggests that early learning is based not on conscious thought but on an automatic ability to associate objects which enables babies to quickly make sense of their environment.
