Researchers Show Evolutionary Theory Adds Up - SpaceDaily  Left: From bugs to trilobite to you and me - and all from a world that got taken over by bugs...   All living plants and animals are likely derived from two primitive species of bacteria, a mathematics professor at the University of Alberta has shown. Dr. Peter Antonelli and a former post-doctoral student of his, Dr. Solange Rutz, used an original mathematical modeling system and software program to evaluate and compare the two main theories of biological evolution. One theory proposes that a "mother" bacteria (Bdellavibrio) and a "father" bacteria (Thermoplasma acidophilum) "exchanged energy" in a stable, dependable, and consistent way about 3.2 billion years ago
Navy Enlists Microbes To Cut Costs - SpaceDaily  Left: Microbes such as these e. coli can be modified to turn certain sugars into a non-natural material used in missile propellants and cholesterol-lowering drugs. Photo Credit: National Institute of Allergy and Infectious Diseases, NIH   Microbes have been exploited for thousands of years to help us make bread and alcohol, and more recently, to make antibiotics and clean up toxic spills. Now the Office of Naval Research is hoping the one-celled organisms will reduce the costs of producing a missile propellant, and in the process, lead to a new age of "bioproduction". With funding from ONR's Green Synthesis of Energetic Materials program, microbiologist John Frost and his team at Michigan State University created strains of microbes that convert certain types of sugars into a non-natural synthetic material, called butanetriol.

Scientists Find New Way To Store Hydrogen Fuel - SpaceDaily  The lack of practical storage methods has hindered the more widespread use of hydrogen fuels, which are both renewable and environmentally clean. The most popular storage methods-liquid hydrogen and compressed hydrogen-require that the fuel be kept at extremely low temperatures or high pressures. But the University of Chicago's Wendy Mao and David Mao have formed icy materials made of molecular hydrogen that require less stringent temperature and pressure storage conditions. The compound that holds the most promise for hydrogen storage, called a hydrogen clathrate hydrate, was synthesized at pressures between 20,000 and 30,000 atmospheres and temperatures of minus 207 degrees Fahrenheit.
