Caterpillar study shows order in the complexity of tropical biodiversity
One of the worlds largest and highest-quality set of observations on live tropical insects and their host plants has led researchers to reinterpret the structure of tropical insect communities. The team of scientists who collaborated on this analysis includes Scott Miller of the Smithsonians National Museum of Natural History, Yves Basset of the Smithsonian Tropical Research Institute, Vojtech Novotny of the Czech Academy of Sciences and George Weiblen of the University of Minnesota. The findings from research in Papua New Guinea will be in the Nov. 22 edition of the Proceedings of the Royal Society of London. The research paper is available on the Web at www.pubs.royalsoc.ac.uk
Due to the present high interest in tropical biodiversity, there have been numerous studies on the subject in the last 20 years. These studies reported little predictability in the structure and composition of tropical insect communities, and they were based on techniques that sample dead insects with little data on their biology. "Predictably Simple: Assemblages of Caterpillars (Lepidoptera) Feeding On Rainforest Trees in Papua New Guinea" is a study that shows a different approach. The study was conducted using 35,942 live caterpillars, each carefully handpicked from the foliage in a lowland rainforest in Papua New Guinea. These caterpillars were then reared to adults, which allowed solid identification of species.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
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.
