Celebrated neuroscientist Michael S. Gazzaniga explains the new science behind an ancient philosophical question.
Scientists at Denmark’s Niels Bohr Institute have figured out a cool new way to lower the temperature of hot semiconductors. In a seemingly paradoxical new study, the scientists showed that light from a laser caused the temperature of semiconductor material to drop–and not by just a few degrees. The temperature fell to -269 Celsius –…
Superstorm Sandy was no freak, say experts, but rather a hint of a coming era when millions of Americans will struggle to survive killer weather. They’re telling us we shouldn’t be surprised that this 900-mile-wide monster marched up the East Coast paralyzing cities and claiming scores of lives. “It’s a foretaste of things to come,”…
Mars had an oxygen-rich atmosphere more than a billion years before the Earth, say scientists. An examination of meteorites and rocks on the planet suggests that oxygen was affecting the Martian surface four billion years ago. On Earth, oxygen did not build up to appreciable quantities in the atmosphere for at least another 1.5bn years….
Two major organizations released climate change reports this month warning of doom and gloom if we stick to our current course and fail to take more aggressive measures. A World Bank report imagines a world 4 degrees warmer, the temperature predicted by century’s end barring changes, and says it aims to shock people into action…
South African scientists say they’ve discovered the most complete skeleton ever of an early human ancestor – in a rock that had lain unnoticed in a lab for years. It was only when a technician noticed a tooth protuding from the stone last month that an investigation and CT scan revealed significant parts of Australopithecus…
NASA is serious about sending astronauts back to the moon’s neighborhood and will likely unveil its ambitious plans soon now that President Barack Obama has been re-elected, experts say. The space agency has apparently been thinking about setting up a manned outpost beyond the moon’s far side, both to establish a human presence in deep…
