An increasing number of new auto buyers choose diesel engines. For asthmatics and those with allergies this is very unfortunate. Particles in diesel exhaust can both worsen and trigger allergic reactions.
"Tough, raw and macho". Such is the advertising for many new off-road vehicles on the market today. They can drive in the mud as well as on pavement and they most often use diesel. It is no longer the “macho boys” that drive these vehicles – now they have also become very popular as family vehicles. The statistics for new autos purchased in February show that almost three out of ten autos that were sold in Norway are fuelled by diesel. In the same period last year, two out of ten autos had diesel engines. But even though the auto industry has successfully made diesel engines cleaner, by among other things installing filters in newer autos, the problem is far from solved. Around 90 percent of heavy traffic in Norway is also fuelled by diesel. And all ships and some trains still have diesel engines.
Great health problem

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.
