Credit: © ESA-C.Carreau A European space mission has achieved the closest thing to a true free fall ever observed for a human-created object, demonstrating the technology needed to build a future observatory that will hunt for gravitational waves far from Earth, scientists said. The two gold-platinum cubes inside the European Space Agency's (ESA) LISA Pathfinder spacecraft are virtually motionless with respect to e..>> view originalEscape From A Black Hole?

How fish and clean water can protect coral reefs from warming oceans
Rebecca Vega Thurber, Oregon State University and Deron Burkepile, University of California, Santa Barbara Hurricanes and waterspouts. Bone-chilling rain and 100 degree Fahrenheit temperatures. Jellyfish and fire coral stings. Broken toes, shoulders, knees and fingers. Entanglements in fishing gear and stranded boats. Cockroaches, mosquitoes and sandflies. Hundreds of SCUBA dives and thousands of hours underwater. And to end it all, mountains of very different kinds of data to ..>> view originalSpaceX's Leaning Rocket Tower Comes Ashore (Photos)

On May 27, the first stage of a SpaceX Falcon 9 rocket helped launch the Thaicom 8 commercial communications satellite from Cape Canaveral Air Force Station in Florida, then came back to Earth on a robotic "drone ship"..>> view originalIce Age Bison Skull Offers Clues About Early Humans In America
Steppe bison fossils offered clues into ancient human settlement in America, showing that early humans likely colonized the area along the Pacific coast and not through the Rocky Mountains corridor as traditionally thought. ( Government of Yukon | UCSC ) Could the bison provide clues to the mystery of ancient American settlement? Bones of giant steppe bison and traces of their ice-age hunters have led researchers to conclude that early humans likely colonized North America sout..>> view originalUS And Chinese Mayors Are Leading The World In The Fight Against Climate Change And Boston Is Out In Front
The United States of America and China are the world's two largest economies. They are also responsible for over one third of global greenhouse gas emissions. In recent years tackling climate change has become a pillar of the U.S.-China bilateral relationship. In April of this year both countries officially signed the historic Paris Agreement and pledged to take respective domestic steps within the year. This week in Beijing I join mayors from cities across China and the U.S. for the second Cl..>> view originalWorld's Most Confused Fish Gets Stuck INSIDE A Jellyfish
It's every photographer's dream to capture a once-in-a-lifetime shot that leaves viewers in total awe. For Australian photographer Tim Samuel, a self-described "ocean lover," that moment came in December while snorkeling off Byron Bay, in New South Wales, when he stumbled across a fish stuck inside a jellyfish. "I really had never seen anything quite like this," Samuel told The Huffington Post in an email. "Lucky I had my camera on me, this seems like a once in a lifetime find." Samuel says the..>> view originalNew algorithm developed at MIT for imaging black holes
Everybody knows you can’t see a black hole. Nothing gets out, not even light. Except that, as with most conventional wisdom, isn’t the whole story. Leaving aside the can of worms labeled Hawking radiation, we still know that the matter falling into a black hole heats up as it falls in. In theory, we can pick that up with a good old radio telescope. But black holes are so far away that we need way better angular resolution than any telescope we currently have, if we want to confirm these predict..>> view original
