Canadian researchers subjected volunteers to a test that required they track a dot moving on a computer screen with a joystick, and volunteers who received stimulation fared much better.http://www.newser.com/story/63792/real-thinking-cap-may-not-be-so-far-off.html?utm_source=syn&utm_medium=rss&utm_campaign=tagTue, 07 Jul 2009 14:44:02 CDThttp://www.newser.com/story/45521/huge-holes-found-in-earths-magnetic-shield.html?utm_source=syn&utm_medium=rss&utm_campaign=tagScientists have discovered two large and unexpected holes in the magnetic field that protects the Earth from solar winds, reports Space.com. The leaks won't pose any risk to health, but increased disruption to satellites and electrical systems can be expected when the cycle of solar storms reaches its next...http://www.newser.com/story/45521/huge-holes-found-in-earths-magnetic-shield.html?utm_source=syn&utm_medium=rss&utm_campaign=tagWed, 17 Dec 2008 2:40:30 CSThttp://www.newser.com/story/42175/you-heard-headphones-pacemakers-dont-jibe.html?utm_source=syn&utm_medium=rss&utm_campaign=tagHeadphones used with digital music players may interfere with pacemakers and internal defibrillators, scientists discovered in research contradicting reports from the US government. “Exposure of a defibrillator to the headphones can temporarily deactivate the defibrillator,” the lead researcher said. Draping the headphones over the chest caused hindrance in 15% of...http://www.newser.com/story/42175/you-heard-headphones-pacemakers-dont-jibe.html?utm_source=syn&utm_medium=rss&utm_campaign=tagSun, 09 Nov 2008 15:25:04 CSThttp://www.newser.com/story/31600/mercury-is-shrinking.html?utm_source=syn&utm_medium=rss&utm_campaign=tagThe planet Mercury is shrinking, the LA Times reports. Data from NASA’s Mercury Messenger spacecraft reveal that the planet’s diameter has shrunk by a mile over its history, probably because its core is cooling. Messenger flew in for a close-up in January, and scientists are now piecing together the new...http://www.newser.com/story/31600/mercury-is-shrinking.html?utm_source=syn&utm_medium=rss&utm_campaign=tagThu, 03 Jul 2008 18:35:01 CDThttp://www.newser.com/story/26540/magnet-molecule-may-guide-bird-migration.html?utm_source=syn&utm_medium=rss&utm_campaign=tagMigrating birds may rely on a special molecule discovered in their eyes that allows them to perceive the Earth’s magnetic field lines as a kind of road map, new research shows. The molecule may help birds navigate much the same way humans follow lines to stay on a highway lane,...http://www.newser.com/story/26540/magnet-molecule-may-guide-bird-migration.html?utm_source=syn&utm_medium=rss&utm_campaign=tagMon, 05 May 2008 8:22:37 CDThttp://www.newser.com/story/18577/solar-lull-may-trigger-ice-age.html?utm_source=syn&utm_medium=rss&utm_campaign=tagSolar activity, which usually runs in 11-year cycles, has been so sluggish of late that space weathermen are worried we might be entering a mini-ice age. They expected to see sunspot activity pick up about last March, to peak in 2012; if the sun stays this sluggish for another year...http://www.newser.com/story/18577/solar-lull-may-trigger-ice-age.html?utm_source=syn&utm_medium=rss&utm_campaign=tagThu, 14 Feb 2008 14:56:00 CSThttp://www.newser.com/story/13977/uber-precise-atomic-clocks-are-half-past-a-revolution.html?utm_source=syn&utm_medium=rss&utm_campaign=tagForget the Swiss—the world's best clocks sit in a Colorado lab where a team of scientists is shaping them into über-precise gadgets with broad-reaching implications on medicine, navigation, and surveillance.
