Rains at the start of the growing season cause vegetation growth. This encourages a feedback loop as the greener the vegetation becomes, the greater the amount of rain that falls.
This Important new research could help us to predict future droughts in Africa. The research can be used to aid regional and international forecasts for rain-starved regions.
Using satellite technology, Dr Sietse Los and colleagues at CLASSIC worked with NASA to develop a dataset covering 18 years of vegetation greenness records. They combined these records with rainfall data in the region over the same period – from 1982 to1999. The resulting analyses show, for the first time, that rainfall amounts vary between 10% and 30% more when the land is green, and decreases by a similar amount when conditions are dry and there is little green vegetation growing.
Dr Los said, “ The role of vegetation in enhancing both wet and dry conditions in sub-Saharan Africa is important for understanding the causes of droughts, which often have dire consequences for the local population. Our research will help to improve current climate models and give better rainfall and vegetation growth predictions. And in turn this will help both climate scientists and local agricultural managers.”

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.
