Key Advance in Understanding 'Pseudogap' Phase in High-Tc Superconductors

Scientists have discovered a fundamental
difference in how electrons behave at the two distinct oxygen-atom sites in a copper-oxide superconductor. Understanding this broken symmetry in the non-superconducting pseudogap phase may lead to new approaches to understanding the pseudogap, long hypothesized as a key hurdle to achieving room-temperature superconductivity.

Secretary of Energy and former Berkeley Lab Director Steve Chu
led the development of a technique that enables the use of optical microscopy to image objects or the distance between them with resolutions as small as 0.5 nanometers--one-half of one billionth of a meter, or an order of magnitude smaller than the previous best. This super-resolution technique has the potential to revolutionize biological imaging, the secretary says.

Study Reveals a Secret to the Success of Notorious, Disease-Causing Microbes
Thu, 22 Jul 2010 11:31:00 -0500
A study published in the July 23 issue of Cell identifies the mechanism used by several types of common, virulent microbes to infect plants and cause devastating blights. Microbes using this infection mechanism include fungi that are currently causing wheat rust epidemics in Africa and Asia, and a class of parasitic algae, called oomycetes, that resulted in the Irish potato blight of the 19th Century. These microbes remain an agricultural scourge today.
