Scientists at Rutgers, The State University of New Jersey, have unlocked an important door to understanding one of the most important crops in the world – corn. Researchers at Rutgers Waksman Institute of Microbiology have redefined the nature of heterosis or hybrid vigor, the phenomenon underlying corns remarkable success. Heterosis is the robustness seen in hybrids when different lines are crossed and result in higher yields than either of the parental lines would produce themselves.
Maize (corn) dominates agriculture in the United States, where, according to the National Corn Growers Association, 9 billion bushels are produced annually at a value of more than $21 billion. No crop rivals its total grain yield or the diversity of its uses. Virtually all corn varieties grown today are hybrids. Understanding the genetic basis of heterosis could revolutionize our thinking about genetics and pave the way to even stronger, healthier or more productive strains.
Rentao Song and Joachim Messing of Rutgers Waksman Institute of Microbiology discuss their findings in a paper published in the July 22 issue of the Proceedings of the National Academy of Science. The paper is currently available online.

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.
