Familiar yet strange: Water's 'split personality' revealed by computer model
Seemingly ordinary, water has quite puzzling behavior. Why, for example, does ice float when most liquids crystallize into dense solids that sink?
Mars' halcyon times may have been fleeting
Cold and dry today, Mars was previously warm and wet but possibly only at intervals, a study published on Sunday suggests.
Bed bugs can survive freezing temperatures, but cold can still kill them
Exposing bed bug-infested clothing or other small items to freezing temperatures may be a viable control option for people at risk of bed bug infestations. However, a new study has found that bed bugs may ...
Team develops device to detect biodiesel contamination
In 2010, a Cathay Pacific Airways plane was arriving in Hong Kong when the engine control thrusts seized up and it was forced to make a hard landing—injuring dozens. The potential culprit? Contaminated fuel.
Alaskan wood frogs stock up on solutes to survive
Outwardly, the tiny wood frog, Rana sylvatica, does not look like your regular arctic inhabitant. Yet despite their tiny stature, these little frogs are actually quite hardy and can tolerate freezing of up ...
Warm ocean drives most Antarctic ice shelf loss, research shows
Ocean waters melting the undersides of Antarctic ice shelves, not icebergs calving into the sea, are responsible for most of the continent's ice loss, a study by UC Irvine and others has found.
Extreme work clothes for the Artic
Roughnecks working on oil and gas installations in the Arctic need clothes that monitor the health. Research scientists at SINTEF are developing a jacket with built-in sensors. It will monitor both body t ...
Synchrotrons explore water's molecular mysteries
(Phys.org)—In experiments at SLAC National Accelerator Laboratory and Lawrence Berkeley National Laboratory, scientists observed a surprisingly dense form of water that remained liquid well beyond its typical ...
Weird world of water gets a little weirder with a new anomaly
Strange, stranger, strangest! To the weird nature of one of the simplest chemical compounds -- the stuff so familiar that even non-scientists know its chemical formula -- add another odd twist. Scientists ...
Stream water study detects thawing permafrost
Among the worrisome environmental effects of global warming is the thawing of Arctic permafrost -- soil that normally remains at or below the freezing point for at least a two-year period and often much longer. Monitoring ...
Experimental explanation of supercooling: Why water does not freeze in the clouds (w/ Video)
Supercooling, a state where liquids do not solidify even below their normal freezing point, still puzzles scientists today. A good example of this phenomenon is found everyday in meteorology: clouds in high ...
Mpemba effect: Why hot water can freeze faster than cold
Freezing point of supercooled water varies with electric charge
