The universe has been mapped! Not the universe of stars, planets, and black holes, but the protein universe, the vast assemblage of biological molecules that are the building blocks of living cells and control the chemical processes which make those cells work. Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have created the first three-dimensional global map of the protein structure universe. This map provides important insight into the evolution and demographics of protein structures and may help scientists identify the functions of newly discovered proteins.
Sung-Hou Kim, a chemist who holds a joint appointment with Berkeley Labs Physical Biosciences Division and UC Berkeleys Chemistry Department, led the development of this map. An internationally recognized authority on protein structures, he expressed surprise at how closely the map, which is based solely on empirical data and a mathematical formula, mirrored the widely used Structural Classification System of Proteins (SCOP), which is based on the visual observations of scientists who have been solving protein structures.
"Our map shows that protein folds are broadly grouped into four different classes that correspond to the four classes of protein structures defined by SCOP," Kim says. "Some have argued that there are really only three classes of protein fold structures but now we can mathematically prove there are four."

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.
They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
