MicroRNAs are a recently discovered large class of small, non-coding genes. Each animal genome contains hundreds of these genes, which have been shown to regulate the expression of protein coding genes by binding to partially complementary sites in messenger RNAs. However, little is known about the biological function of these tiny genes, which are encoded in a string of 21 to 24 DNA bases.
In a series of four high-profile papers in Nature, Nature Genetics, Developmental Biology, and PloS Computational Biology published over the past 15 months, researchers at New York Universitys Center for Comparative Functional Genomics have shed light on the function and evolution of microRNA across a wide set of genomes. Their newest findings appear in the inaugural issue of Public Library of Sciences journal, PloS Computational Biology.
This study, headed by NYU Assistant Biology Professor Nikolaus Rajewsky, included researchers Dominic Grün, Yi-Lu Wang, and David Langenberger, and Research Assistant Professor Kristin Gunsalus, all at NYUs Center for Comparative Functional Genomics. By comparing seven recently sequenced fly species, they found that thousands of genes in the genome of a laboratory model organism--the fruit fly--are likely to be regulated by microRNAs.

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.
