Quantum processes involved in photosynthesis? "[A]lgae and bacteria may have been performing quantum calculations at life-friendly temperatures for billions of years. The evidence comes from a study of how energy travels across the light-harvesting molecules involved in photosynthesis. The work has culminated this week in the extraordinary announcement that these molecules in a marine alga may exploit quantum processes at room temperature to transfer energy without loss. Physicists had previously ruled out quantum processes, arguing that they could not persist for long enough at such temperatures to achieve anything useful." (via mr)

Using photosynthesis to power hydrogen production
Researchers have found that if they insert platinum nanoclusters into the photosynthetic machinery of bacteria, one acre could produce an amount of hydrogen equivalent to 79 gallons of gas per day. [more inside]
