Hold the ice: Research reveals behavior of antifreeze molecules

Chemists at New York University have discovered a family of anti-freeze molecules that prevent ice formation when water temperatures drop below 32 degrees Fahrenheit. Their findings, which are reported in the latest issue ...

Finding may end a 30-year scientific debate

A chance observation by a Queen's researcher might have ended a decades-old debate about the precise way antifreeze proteins (AFP) bind to the surface of ice crystals.

Physicists find evidence of new state of matter in a simple oxide

Symmetry is a fundamental concept in physics. Our ‘standard model’ of particle physics, for example, predicts that matter and anti-matter should have been created in equal amounts at the big bang, yet our existing universe ...

The secret life of water at very low temperatures

The secret life of water just got weirder. For years water has been known to exist in 15 phases -- not just the merry threesome of solid, liquid and gas from grade school science. Now, University of Utah chemists have confirmed ...

Freezing: a phenomenon that 'jumps'

(PhysOrg.com) -- The freezing of suspensions of particles is not always a uniform phenomenon; in certain conditions it leads to a modification of the redistribution of particles and the growth of crystals.

Increase in forest fires may damage the crucial ozone layer

All particles that reach the atmosphere cause different chemical reactions. Particles come partly from natural sources such as volcanic eruptions and forest fires, and partly from pollution and emissions. Aerosol researcher ...

Why don't insects freeze solid in the Arctic?

Life in the Arctic is harsh. Arctic temperatures are punishing, making life difficult for many animals to survive. Yet lots of insects, including mosquitoes, manage to thrive in the frozen region. So why don't they freeze ...

Studying clouds can provide deeper insight into climate change

An international team of scientists conducted CALISHTO, a large-scale air measurement campaign in Greece last fall, with the goal of surveying, counting and characterizing the tiny particles and their impact on cloud formation. ...
