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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
