A special place on the market of food supplements belongs to ecdysteroid-containing preparations that are helpful as a tonic for sportsmen during intensive training sessions, for people of various professions connected with physical and psychological stresses, and also for elderly people. Ecdysteroids heal wounds and burns.
A plant containing very high concentrations of ecdysteroids has been found by a team headed by Vladimir Volodin from the Institute of Biology in Syktyvkar. This is saw-wort (Serratula coronata). Its leaves contain more significant amounts of the active component than the roots of rhaponticum (Leuzea carthamoides) used as a medicinal plant in the former USSR. A saw-wort plantation is raised by the researchers in Syktyvkar; the plants have adapted to the northern conditions and successfully produce the active component.
The technology for ecdysteroid extraction from plant material is already designed and patented. In addition, a method for cultivating plant cells is known. Cell cultures that resemble white live clumps perfectly grow in laboratory and produce phytoecdysteroids in sufficient quantities. These cultures are added to the collection of the Institute of Plant Physiology of the Russian Academy of Sciences (Moscow).

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
