Grey is the new black hole: is Stephen Hawking right?
Over the past few days, the media has cried out the recent proclamation from Stephen Hawking that black holes, a mystery of both science and science fiction, do not exist. ...
The "Potsdam gravity potato" shows variations in Earth's gravity
People tend to think of gravity here on Earth as a uniform and consistent thing. Stand anywhere on the globe, at any time of year, and you'll feel the same downward pull of a single G. But in fact, Earth's ...
Engineers building hard-working mining robot
(Phys.org)—After decades of designing and operating robots full of scientific gear to study other worlds, NASA is working on a prototype that leaves the delicate instruments at home in exchange for a sturdy ...
Do homing pigeons navigate with gyroscope in brain?
No one knows how homing pigeons do it, but now a team of Swiss and South African scientists have discovered that the bird's navigation is affected by disturbances in gravity, suggesting that they navigate ...

Out-of-fuel European satellite to come crashing down
A satellite monitoring Earth's gravity field since 2009 will run out of fuel "in the coming days" and eventually crash, with little risk to humans, the European Space Agency said Friday.
New map exposes previously unseen details of seafloor
Accessing two previously untapped streams of satellite data, scientists at Scripps Institution of Oceanography at UC San Diego and their colleagues have created a new map of the world's seafloor, creating ...
