A simple sleeping bag could solve one of the biggest health risks of space travel
Astronauts who spend extended periods of time in space are at high risk for a vision issue called spaceflight-associated neuro-ocular syndrome (SANS). When we sleep on earth, the blood and spinal fluid that flows to our head while we’re sleeping naturally drains away when we get up in the Read More...
Barcelona’s bus fleet will soon run on biofuel made from sewage sludge

The reaction yielded 1.3 megajoules of energy, a higher amount than the input of fuel it took to power the reactor. The group of physicists at the Lawrence Livermore National Laboratory responsible for this Read More...
Robots can now reproduce on their own
Created using cutting edge biotechnology, xenobots are the world’s first living robots. They can amazingly make decisions and reproduce all on their own. These tiny living machines made out of frog cells duplicate themselves by collecting resources from the environment, with their offspring going Read More...
Researchers say Viagra could potentially treat Alzheimer's disease
