New Material Grabs More Solar Energy - Space.com  Researchers from Lawrence Berkeley National Laboratory, the University of California, and the Massachusetts Institute of Technology have engineered a single material that contains three bandgaps and is capable of capturing more than 50 percent of the sun's energy. The researchers made the material by forcing oxygen into a zinc-manganese-tellurium crystal. The oxygen split the crystal's band gap and formed a third one of its own.  
Analysis Uncovers Critical Stretches of Human Genome  - SpaceDaily  Hundreds of stretches of DNA may be so critical to life's machinery that they have been "ultra-conserved" throughout hundreds of millions of years of evolution. Researchers have found precisely the same sequences in the genomes of humans, rats, and mice; sequences that are 95 to 99 percent identical to these can be found in the chicken and dog genomes, as well. Most of these ultra-conserved regions do not appear to code for proteins, but may instead play a regulatory role. Evolutionary theory suggests these sequences may be so central to mammalian biology that even small changes in them would compromise the animal's fitness.

Polymer Electrolyte Membrane Brings High-Temp PEM Cells Closer - SpaceDaily  A new type of polymer electrolyte membrane (PEM) is being developed by researchers at the Department of Energy's Sandia National Laboratories to help bring the goal of a micro fuel cell closer to realization using diverse fuels like glucose, methanol, and hydrogen. This Sandia Polymer Electrolyte Alternative (SPEA) could help fulfill the need for new, uninterrupted autonomous power sources for sensors, communications, microelectronics, healthcare applications, and transportation. Because the SPEA material can operate at elevated temperatures, it enables several key benefits.
