First polymer solar-thermal device heats home, saves money
— 4 Apr 2011 18:12 | TechnologyA new polymer-based solar-thermal device is the first to generate power from both heat and visible sunlight - an advance that could shave the cost of heating a home by as much as 40…
Astrophysicist: White dwarfs could be fertile ground for other Earths
— 31 Mar 2011 15:03 | AstronomyPlanet hunters have found hundreds of planets outside the solar system in the last decade, though it is unclear whether even one might be habitable. But it could be that the best place…
Berkeley Lab researchers make first perovskite-based superlens for the infrared
— 30 Mar 2011 16:22 | TechnologySuperlenses earned their superlative by being able to capture the 'evanescent' light waves that blossom close to an illuminated surface and never travel far enough to be 'seen' by a…
