| Shearing triggers odd behavior in microscopic particles Posted: 23 Dec 2011 06:15 AM PST Microscopic spheres form strings in surprising alignments when suspended in a viscous fluid and sheared between two plates, a finding that will affect the way scientists think about the properties of such wide-ranging substances as shampoo and futuristic computer chips.  |
| New method for watching proteins fold Posted: 23 Dec 2011 06:14 AM PST A protein's function depends on both the chains of molecules it is made of and the way those chains are folded. And while figuring out the former is relatively easy, the latter represents a huge challenge with serious implications because many diseases are the result of misfolded proteins. Now, a team of chemists has devised a way to watch proteins fold in "real-time," which could lead to a better understanding of protein folding and misfolding in general.  |
| Noise-free spectroscopy: Reversing the problem clarifies molecular structure Posted: 23 Dec 2011 06:13 AM PST Optical techniques enable us to examine single molecules, but do we really understand what we are seeing? After all, the fuzziness caused by effects such as light interference makes these images very difficult to interpret. Researchers have now adopted a "reverse" approach to spectroscopy which cleaned up images by eliminating background noise.  |
