Winds and changing climate converted parts of Oklahoma, Kansas, Colorado and Texas into a giant ’dust bowl’ in the 1930s. In response, the 1937 ’Shelterbelt Project’ involved the planting of trees to reduce erosion and provide relief from the biting winds that blew soil from farms and drove people west to California. Now, almost 75 years later, NASA scientists have found that planting trees also can significantly reduce carbon dioxide in the atmosphere.
Tree planting and insect control could greatly affect Earth’s greenhouse gases – those gases in the atmosphere that warm the planet – according to NASA scientists who presented their findings this December during the American Geophysical Union’s fall meeting in San Francisco.
“Planting trees on marginal agricultural lands could ’sequester’ carbon and offset at least one-fifth of the annual fossil fuel emission of carbon in the United States,” said Christopher Potter, a scientist at NASA Ames Research Center in California’s Silicon Valley. “Scientists also have found that outbreaks of plant-eating insects may be linked with periodic droughts and heat waves in North America, which can trigger large seasonal losses of carbon dioxide back to the atmosphere.” Potter added.

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.
