 Researchers in Belgium have developed a technique that allows coma patients that are in a minimally-conscious state to become aware enough to communicate — for up to a week — using mild electrical stimulation to their brains.

Building on the results of a 2014 study that showed that electrical stimulation of the brain could briefly help raise the state of awareness in coma patients, a research team from Belgium’s University of Liège performed a similar experiment using longer sessions, where 16 participants, either in a minimally conscious or vegetative state, were given 20-minute treatments for five days.

Three top-secret satellites launched by Russia between 2013 and 2015 have recently been reactivated, and appear to be carrying out missions to rendezvous with other man-made objects in orbit, performing comparatively dramatic maneuvers to make their intercepts. Despite assurances from the Russian government that these vehicles are benign, there is speculation that these satellites might be anti-satellite weapons, designed to maneuver close to another satellite and destroy it with an onboard weapon.

The water subsequently froze on the floor of the tunnel, prompting the vault’s caretakers to chip the ice away from the tunnel floor.

The definitive dating of the remains of the extinct hominin Homo naledi has been completed, and the results have left researchers’ original assumptions about the age of the creature in the dust: initially thought to be 2.5 million years old, the remains have been found to be only one-tenth of that age, at roughly 250,000 years — meaning that this species co-existed with modern humans.
