Ian Burkhart, a 23-year-old quadriplegic from Dublin, Ohio, is the first patient to use Neurobridge, an electronic neural bypass for spinal cord injuries that reconnects the brain directly to muscles, allowing voluntary and functional control of a paralyzed limb. Burkhart is the first of a potential five participants in a clinical study.

"It's much like a heart bypass, but instead of bypassing blood, we're actually bypassing electrical signals," said Chad Bouton, research leader at Battelle. "We're taking those signals from the brain, going around the injury, and actually going directly to the muscles."

Jupiter's largest moons don't go completely dark when the giant planet blocks their sunlight, astronomers have found.

The discovery could reveal more about Jupiter's mysterious upper atmosphere, which the researchers suspect is responsible for keeping the moons lit when they are not directly illuminated by the sun. This research could also help scientists better understand the atmospheres of alien planets, study team members said.

Looks like time travel is possible… for particles of light.

Using a photon, physicists have managed to simulate quantum particles traveling through time. Studying the photon's behavior could help scientists understand some inexplicable aspects of modern physics.

"The question of time travel features at the interface between two of our most successful yet incompatible physical theories — Einstein's general relativity and quantum mechanics," University of Queensland's Martin Ringbauer says in a news release. "Einstein's theory describes the world at the very large scale of stars and galaxies, while quantum mechanics is an excellent description of the world at the very small scale of atoms and molecules."
