Team Maps Dark Matter In Startling Detail - SpaceDaily  Left:  On the top is an ACS image that shows the lensed galaxy elongated vertically by gravity. However, when the same galaxy is observed with the Very Large Telescope (VLT) at Cerro Paranal, we only see a small blob indicating no hints of lensing (below). The shape information has been destroyed by the atmospheric turbulence even if it is much weaker there than at the sea level.  "Advances in computer technology now allow us to simulate the entire universe and to follow the coalescence of matter into stars, galaxies, clusters of galaxies and enormously long filaments of matter from the first hundred thousand years to the present," Jee said. "However, it is very challenging to verify the simulation results observationally, because dark matter does not emit light." "The images we took show clearly that the cluster galaxies are located at the densest regions of the dark matter haloes, which are rendered in purple in our images," Jee said  Dark matter presents one of the most puzzling problems in modern cosmology. Invisible, yet undoubtedly there scientists can measure its effects its exact characteristics remain elusive. Previous attempts to map dark matter in detail with ground-based telescopes were handicapped by turbulence in the Earth's atmosphere, which blurred the resulting images. The clumped structure of dark matter around the cluster galaxies is consistent with the current belief that dark matter particles are "collision-less," Jee said. Unlike normal matter particles, physicists believe, they do not collide and scatter like billiard balls but rather simply pass through each other. 
Portugal Turns To Renewables To Reduce Oil Dependence - SpaceDaily   Left: The clumped structure of dark matter around the cluster galaxies is consistent with the current belief that dark matter particles are "collision-less," Jee said. Unlike normal matter particles, physicists believe, they do not collide and scatter like billiard balls but rather simply pass through each other.  Portugal is turning to wind, wave and solar power to reduce its huge dependence on oil imports and meet its international commitments to reduce carbon dioxide emissions. The world's first commercial wave power plant is set to begin operating off Portugal's northern coast in 2006 while work on the world's biggest solar power station will begin in the sunny south of the country next year.    

Walker's World: A 4x4 coalition emerging? - SpaceDaily  The Bush Administration is quietly seeking to build with Britain, Japan and India a globe-spanning coalition system that can contain China, claims a leading neo-conservative thinker. In a new essay just published by the AEI, titled "The Big Four Alliance: The New Bush Strategy," Donnelly says that "far from maintaining a unilateralist approach to American security," the Bush administration has been forging a strategic partnership structure that can help to manage the rise of China, while also buttressing the liberal international order of free trade, free markets and expanded democracy.
