Quantum effects help cells capture light, but the details are obscure
Reston VA (SPX) Dec 09, 2013
Sophisticated recent experiments with ultrashort laser pulses support the idea that intuition-defying quantum interactions between molecules help plants, algae, and some bacteria efficiently gather light to fuel their growth. But key details of nature's vital light-harvesting mechanisms remain obscure, and the exact role that quantum physics may play in understanding them is more subtle than was once thought, according to an Overview Article in the January issue of BioScience. The article, b ... read more
