Plants and bacteria make use of sunlight with remarkably high efficiency: nine out of ten absorbed light particles are being put to use in an ordinary bacterium. For years, it has been a pressing question of modern research whether or not effects from quantum physics are responsible for this outstanding performance of natural light harvesters. A team of European research groups, a collaboration between universities in Vienna, Ulm, Cartagena, Prague, Berlin and Lund, have examined these quantum effects in an artificial model system. (2015-07-13)

Light is the friend of lovers
The increase of artificial night lighting is only one of the consequences of intense urbanization. There is no doubt that chemical and noise pollution can have a strong impact on ecosystems. To date, however, the more subtle consequences of light pollution on wild populations of animals have not received enough attention. Scientists of the Max Planck Institute for Ornithology have now shown that permanent night lighting alters the reproductive behaviour of birds. In those habitats that are affected by artificial light, males started to sing earlier and females advanced the onset of breeding activities. Moreover, males occupying territories with street lights had a higher number of extra-pair mates than males living in dark forests. (2010-09-17)

How light is detected affects the atom that emits it
A lab at Washington University in St. Louis is one of the first in the world to look at spontaneous emission with an instrument sensitive to the wave rather than the particle nature of light. Because the light is entangled with the atom that emitted it, this kind of detection may provide a way to control the quantum state of the atom. (2016-05-12)
