Billions Investment Needed for Hydrogen Infrastructure By 2012: ABI Research - SpaceDaily  The embryonic automotive fuel cell industry - whether or not aided by governments - must invest some US$2 billion in creating a hydrogen fueling station infrastructure by 2012 if market expectations are to be met. Natural gas, coal, ethanol and methanol, biomass gasification, electrolysis, solar and wind energy, even nuclear reactions are all potential sources for the hydrogen needed to run fuel cells, and the study analyzes each in detail, with particular emphasis on natural gas, the most likely candidate. Will the hydrogen supply chain be up to the task? Yes, if sufficient R&D funding is directed to production technologies and storage methods.    
Super-Heavy Nuclei Take Shape In 'Extreme' New Theories - SpaceDaily  Left: Oak Ridge National Laboratory researchers report that experiments and computer simulations are enabling nuclear physicists to predict deformations and shapes for the heaviest elements in and beyond the current Periodic Table. The Z=110-113 alpha-decay chains found at GSI, Germany, and RIKEN, Japan, (the green arrows) go through prolate shapes (in the red-orange area) while the heavier, Z=114-118 chains reported in Dubna, Russia (the blue arrows) start in a region of oblate shapes (the blue-green area). See larger image.   Some experiments indicate that the addition of neutrons to a nucleus can extend the life of an isotope of a superheavy element -- for instance the as-yet unnamed element 112 -- from a fraction of a second to more than 30 seconds. In terms of existence for extremely heavy nuclei, a half-minute is an eternity. Lead-208 is the heaviest "doubly magic" nucleus with closed shells of 82 protons and 126 neutrons.   

String Theorist Explores Dark Energy And Our Unique 'Pocket' Of The Universe - SpaceDaily  Dark energy doesn't just exist-it dominates. Only 5 percent of the universe is ordinary matter. Another 25 percent is dark matter-matter that scientists cannot "see" but whose existence is suggested because of the effects of its gravity on the rotation and clustering of galaxies. A whopping 70 percent of the universe is dark energy. dark energy-also called vacuum energy-is a property of empty space. In recent years, some physicists have suggested that rather than having one universe with one set of physical laws, string theory may lay the foundation for the possibility of the existence of innumerable "pocket universes," each with their own landscape of physical laws.
