Team charts new understanding of actin filament growth in cells

University of Oregon biochemists have determined how tiny synthetic molecules disrupt an important actin-related molecular machine in cells in one study and, in a second one, the crystal structure of that machine when bound ...

Theory of crystal formation complete again

(Phys.org)—Exactly how a crystal forms from solution is a problem that has occupied scientists for decades. Researchers at Eindhoven University of Technology (TU/e), together with researchers from Germany and the USA, are ...

A 3.45-billion-year-old diet

Researchers are providing new information about the 'diet' of microorganisms on the early Earth. By studying 3.45-billion-year-old rocks, the team uncovered clues about ancient microbial metabolism.

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 ...

Repulsive interactions

(PhysOrg.com) -- The recent state of the roads is a clear illustration of what happens when water freezes into crystals of ice. But despite its frequent occurrence, the crystallisation of water is remarkably difficult to ...

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 ...

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. ...
