Astronomers at The University of Texas at Austin and Harvard University have put a basic principle of black holes to the test, showing that matter completely vanishes when pulled in. Their results constitute another successful test for Albert Einstein’s General Theory of Relativity.
Researchers have struggled for decades to safely use powerful—but flammable—lithium metal in a battery. Now John Goodenough, the 94-year-old father of the lithium-ion battery, is claiming a novel solution as a blockbuster advance.
Their intelligence is all the more striking because it has evolved completely independently of the line that gave rise to us: our last common ancestor—perhaps some simple, slug-like creature—lived well over 540 million year ago.
Kalaupapa, Hawaii, is a former leprosy colony that’s still home to several of the people who were exiled there through the 1960s. Once they all pass away, the federal government wants to open up the isolated peninsula to tourism. But at what cost?
Director of Sciences Janna Levin invites neuroscientist Christof Koch (President and Chief Scientific Officer of the Allen Institute for Brain Science) and philosopher David Chalmers (Director of the Center for Mind, Brain and Consciousness at New York University) to ask: Do androids actually dream of electric sheep?
There's a growing body of evidence that cuttlefish are smart enough to assess the relative strength of their opponents to gauge their odds before fighting. They modify their behaviors – including their skin patterns – accordingly.
Octopuses and cuttlefish are masters of underwater camouflage, blending in seamlessly against a rock or coral. But squid have to hide in the open ocean, mimicking the subtle interplay of light, water, and waves. How do they do it?
