Quantum biology: Algae evolved to switch quantum coherence on and off
A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
Researchers confirm 60-year-old prediction of atomic behavior
Researchers at Washington State University have used a super-cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since.
Quantum-to-classical transition may be explained by fuzziness of measurement references
Quantum effects help cells capture light, but the details are obscure
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. ...

On a clear day: Noise-induced quantum coherence increases photosynthetic yield
Noise is not necessarily detrimental to quantum devices
The researches of the Aalto University and the University of Oulu have succeeded to simulate a phenomenon called motional averaging, which demonstrates that in certain conditions externally-induced fast fluctuations ...
Powering lasers through heat
In micro electronics heat often causes problems and engineers have to put a lot of technical effort into cooling, for example micro chips, to dissipate heat that is generated during operation. Austrian physicists ...
