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.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
