The Hubble Space Telescope should be back in action soon, following a tricky, remote repair job by NASA.  The orbiting observatory went dark in mid-June, with all astronomical viewing halted.  NASA initially suspected a 1980s-era computer as the source of the problem. But after the backup payload computer also failed, flight controllers at Maryland’s Goddard Space Flight Center focused on the science instruments’ bigger and more encompassing command and data unit, installed by spacewalking astronauts in 2009.  This image of the Eagle Nebula, captured by the Hubble Space Telescope, shows …

In a medical first, researchers harnessed the brain waves of a paralyzed man unable to speak — and turned what he intended to say into sentences on a computer screen. It will take years of additional research but the study, reported Wednesday, marks an important step toward one day restoring more natural communication for people who can’t talk because of injury or illness. “Most of us take for granted how easily we communicate through speech,” said Dr. Edward Chang, a neurosurgeon at the University of California, San Francisco, who led …
