WASHINGTON — The Office of Space Commerce has rolled out its proposal for a “light touch” approach to mission authorization, the latest attempt in a long-running effort to regulate new commercial space applications. The office released its draft mission authorization proposal late March 24. The White House had directed the Commerce Department in a commercial

The glymphatic system is comprised of channels that clear waste from the brain CLAUS LUNAU/SCIENCE PHOTO LIBRARY Drugs that boost our brain’s waste-disposal system so it can better remove proteins associated with Alzheimer’s disease have been identified for the first time. The combination of a therapy that is commonly used as a sedative with a

TAMPA, Fla. — Amazon vowed to double the annual launch rate for its low Earth orbit broadband constellation to more than 20 missions, hinging largely on rockets yet to prove themselves at scale. With three more missions slated in the coming weeks, the company said March 23 it is on pace to complete 11 launches

A few years ago, I took a zombie test. I had flown to Madison, Wisconsin, to visit neuroscientist Giulio Tononi and learn about his much-debated theory of consciousness, integrated information theory. The most tangible outcome of Tononi’s work is a consciousness detector, which has been used to check whether unresponsive patients are wide awake inside.
