(PhysOrg.com) -- A home energy system that uses water, sunlight, and hydrogen has been released by Japan's FC-R&D. The system is called ZEEP24, where electricity is generated during the day using solar panels. Hiroshi Nakijima, ...
Do animals that have evolved for millions of years underground, completely isolated from the day-night cycle, still "know" what time it is? Does a normal circadian clock persist during evolution under constant darkness? A ...

(PhysOrg.com) -- In an attempt to mimic the photosynthetic systems found in plants and some bacteria, scientists have taken a step toward developing an artificial light-harvesting system (LHS) that meets one of the crucial ...
(PhysOrg.com) -- Astronomers have discovered the darkest known exoplanet - a distant, Jupiter-sized gas giant known as TrES-2b. Their measurements show that TrES-2b reflects less than one percent of the sunlight falling on ...
