Professor Luis Corrochano Peláez, from the Genetics Department of the University of Seville, and his PhD student Julio Rodríguez Romero, in collaboration with researchers of the Duke University of USA and the University of Salamanca, have identified a gene that allows Phycomyces fungus to react to light and orientate their growth toward it. Results will be published in the prestigious journal “Proceedings of the National Academy of Sciences USA” next week. These researches are part of the scientific activity of the Genetics Department of the University of Seville, which has a long-standing tradition in basic research and research applied to the genetics of microorganisms.
Phycomyces blakesleeanus fungus is used in labs to research into the mechanisms that allow living creatures to relate to their environment. The fruiting body of the Phycomyces is sensitive to several environmental stimulus, such us the light, gravity, wind and the presence of close obstacles that modify the speed and direction of its growth. Like plants, Phycomyces grows in the direction of light, against gravity.
In the 1960’s, Nobel prize-winner Max Delbrück started in his lab, in the California Institute of Technology, to search for night-blind mutants of Phycomyces whose fruiting bodies could not move toward the light. These mutants were called mad in honour to Max Delbrück, whose birth centenary is this year, and were used to research into the mechanisms responsible for sight.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
