Rather than using fuel, Milner hopes to use powerful Earth-based lasers to give it a boost.Brain implant helps quadriplegic play Guitar HeroAfter Ian Burkhart broke his neck and lost all movement below his shoulders at age 19, his brain still told his hands how to move—but the messages couldn’t get through his severed spinal cord. Now, thanks to recent advances in electrical stimulation technology, Burkhart can once again grasp, pour, swipe a credit card, and even play Guitar Hero. To do so, he uses a microelectrode array that reads his brain’s signals and sends them through wires to a gel sleeve that electronically stimulates his muscles.NASA’s planet hunter safe again, for nowNASA has regained control of its exoplanet discovery satellite Kepler following a fraught few days during which the spacecraft had put itself into a protective “emergency mode.” What went wrong is not yet clear, but on Sunday morning controllers had the spacecraft in a stable state with its communications antenna pointing toward Earth, ready to send data about the hiccup.   Parasitic worms may prevent Crohn’s disease by altering bacterial balanceThe parasitic worms that lurk in some people’s intestines may be revolting, but they seem to forestall Crohn’s disease and other types of inflammatory bowel disease. A new study might explain how, revealing that the worms enable beneficial microbes in the intestines to outcompete bacteria that promote inflammation. The results could lead to new ways of treating gut diseases by mimicking the effects of the parasites. Email Sign up for our daily newsletter Get more great content like this delivered right to you!

Surprisingly, people playing an online game came up with better strategies for moving the atom than a computer algorithm alone—even finding solutions that were faster than what the physicists had assumed was a speed limit set by quantum mechanics itself.Russian billionaire unveils big plan to build tiny interstellar spacecraftlast_img read more
