The problem of hospital infection, severe disease caused by antibiotic-resistant staphylococcus bacteria, entails major costs and great suffering. Group A streptococcus bacteria, also called meat-eating killer bacteria, are another growing problem. A team of Lund scientists in Sweden has now developed a substance called Cystapep, which seems to work on bacteria that nothing else seems to be able to knock out.
If Cystapep delivers what it promises, this is nothing short of sensational. Sweden is in a better position than other countries when it comes to antibiotic resistance, but in other parts of the world dangerous strains of bacteria have developed resistance to most of the antibiotics doctors have in their arsenal, and the problem is growing worse every year in Sweden as well.
Cystapep took its name from the fact that it is a peptide (a small molecule) that is based on a larger protein called cystatin. Cystatin occurs in various forms in the body and is part of our natural protection against bacteria, fungi, and viruses. The Lund researchers Aftab Jasir and Claes Schalén, medical microbiology, and Anders Grubb, clinical chemistry, have collaborated with a team of Polish scientists to cultivate and develop the segment of cystatin C protein that has proven to provide the best protection.

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.
