Instead of applying a deicing agent to strip ice from an aircraft's wings before stormy winter takeoffs, airport personnel could in the future just watch chunks slide right off without lifting a finger. Scientists report ...

Freezing water is a central issue for climate, geology and life. On earth, ice and snow cover 10 percent of the land and up to half of the northern hemisphere in winter. Polar ice caps reflect up to 90 percent of the sun's ...

A team of researchers from several institutions in France, the U.S. and Sweden has used models of possible conditions on Mars to show that the red planet may have sported a northern ocean 3 billion years ago and that the ...
Seemingly ordinary, water has quite puzzling behavior. Why, for example, does ice float when most liquids crystallize into dense solids that sink?

Researchers at the Department of Physiology and Biophysics, University of Washington, Seattle, have discovered something peculiar in the survival strategy of the snow fly (Chionea spp.), a flightless crane fly that lives ...
Water has many unusual properties, such as its solid form, ice, being able to float in liquid water, and they get weirder below its freezing point. Supercooled water—below freezing but still a liquid—is notoriously difficult ...

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 to two-thirds of ...

Can water reach minus 263 degrees Celsius without turning into ice? Yes it can, say researchers from ETH Zurich and the University of Zurich, if it is confined in nanometre-scale lipid channels.

There are few things more central to life on earth than water. It dominates the physical landscape, covering much of the planet as oceans. It's also a major component of the human body, comprising, for example, more than ...
