An iceberg twice the size of Manhattan tore off one of Greenland’s largest glaciers. For several years, scientists had been watching a long crack in the floating ice shelf of the northerly Petermann Glacier. Now, NASA satellites show it has broken completely, forming an iceberg covering 46 square miles. The same glacier spawned an iceberg…
Rep. Lamar Smith, the chairman of the House Judiciary Committee, may be getting ready to support legislation to grant green cards to holders of advanced degrees in the so-called STEM fields. The Texas republican, the gatekeeper on immigration bills in the House, is being urged to take action by a broad coalition of groups, including…
The new science of self-control shows that religious themes can bolster willpower
The headline on the press release about a new report warns of “R&D trends posing a threat” to the U.S. economy. Scary words, to be sure, especially coming from the presidentially appointed National Science Board, the policy-setting body for the $7 billion a year National Science Foundation. But the data upon which the board bases…
The arguments against an electric car are growing fewer. A vehicle in development by ECOmove – a consortium of Danish car builders – has unveiled a car that can travel 500 miles without refueling. Once a sticking point for electric vehicles, distance could be ticked off the list of grievances the driving populace has with…
The thieving habits of rodents have emerged as an unlikely salvation of tropical forests, research suggests. Massive mammals known as gomphotheres once ranged the Americas, distributing big tree seeds as they roamed. But they are extinct, and it has not been clear what is spreading seeds now. In Proceedings of the National Academy of Sciences,…
Scientists have identified the largest ancient Mayan dam, constructed from stone and holding back around 20 million gallons of water in a man-made reservoir. The Tikal dam stretched more than 260 feet in length and was 33 feet high, and sheds new light on how the Maya conserved their natural resources for over 1,500 years….
For years, scientists have known that man-made underwater noise from an array of sources can deafen or harm whales and other sea mammals. Now, according to The New York Times, scientists say whales can turn down the volume to help protect themselves. “It’s equivalent to plugging your ears when a jet flies over. It’s like a…
If we fail to understand and take care of the natural world, it can come back to haunt us in ways we know little about. A critical example is a developing model of infectious disease that shows that most epidemics — AIDS, Ebola, West Nile, SARS, Lyme disease and hundreds more that have occurred over…
Big scientific discoveries, such as the God particle, can have great Earthly potential that must be shared by the world’s poor. The announcement from CERN that we now have compelling evidence for the Higgs boson — the elementary particle that, according to theory, allows other particles to obtain mass — is widely acknowledged as a…
