NASA scientists have the first evidence more regional pollution lurks in clouds than in clear skies off the Asian coastline. This finding has implications for space-based attempts to monitor global pollution and for other populated regions around the world.
Scientists estimate that roughly two-thirds of Asian pollution from the Pacific Rim flows to the western, North Pacific Ocean under cloudy conditions. They based the study on direct measurements taken in and around clouds by aircraft instruments during the Transport and Chemical Evolution over the Pacific (TRACE-P) field experiment.
"The idea that clouds can be associated with pollution transport is not new, but the TRACE-P observations provide the first evidence of a cloud-pollution link over a large region," said Jim Crawford, the TRACE-P deputy mission scientist at NASA Langley Research Center.

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.
