    The surprising discovery of "square ice" which forms at room temperature was made by an international team of researchers last week. The study was published in Nature by a team of scientists from UK and Germany led by Andre Geim of University of Manchester and G. Algara-Siller of University of Ulm. The accompanying review article was done by Alan Soper of Rutherford Appleton Laboratory in UK. "We didn't expect to find square ice ... We found there is something strange in terms of water going through [nanochannels]. It's going too fast. And you can't explain that by just imagining a...

    College Park, MD (July 27, 2010) -- Earth's climate is strongly influenced by the presence of particles of different shapes and origins -- in the form of dust, ice and pollutants -- that find their way into the lowest portion of the atmosphere, the troposphere. There, water adsorbed on the surface of these particles can freeze at higher temperatures than pure water droplets, triggering rain and snow. Researchers at Spain's Centre d'Investigació en Nanociència i Nanotecnologia (CIN2) have studied the underlying mechanisms of water condensation in the troposphere and found a way to make artificial materials to control water condensation...

    Scientists are reporting that, for the first time, they have made an artificial prion, or misfolded protein, that can, by itself, produce a deadly infectious disease in mice and may help explain the roots of mad cow disease. The findings, being reported today in the journal Science, are strong evidence for the "protein-only hypothesis," the controversial idea that a protein, acting alone without the help of DNA or RNA, a cousin of DNA, can cause certain kinds of infectious diseases. The concept was introduced in 1982 by Dr. Stanley Prusiner, a neurology professor at the University of California, San Francisco,...
