A new Concept in Microscopy:
Self-reconstructing Laser Beams - published in 'Nature Photonics' Researchers at the University of Freiburg are developing a microscope with illuminating beams that actively refocus in a light-scattering medium. Freiburg, 12. It's a familiar situation for all car drivers. In the autumn, when the roads are foggy, visibility drops below 50 metres.

Do you want some ice in your glass of water?
Life is made possible by the abundant presence of water on our planet. But what is special about water compared to other liquids? Atomic studies show that this liquid is composed of a large number of co-existing structures, including crystal-like structures as in ice even at room temperature. This scenario is radically different with respect to other liquids that look homogeneous at all scales.
