A submarine seismic sensor was recently set in place at 2400 m depth, off Toulon. The instrument was attached to a neutrino telescope developed by the international scientific programme Antares (1) . For the first time in Europe, this sensor, designed by a partnership between Géosciences Azur (Mixed Research Unit IRD/CNRS/UPMC/UNSA, Villefranche sur Mer)(2) and Guralp System (United Kingdom), with the financial support of INSU, Villefranche Oceanological Observatory and the Provence-Alpes-Côte dAzur Regional Council, can send real-time deep-sea seismic activity data recorded for the region and for the whole world.
Deployment of this broad-band sensor by the IFREMER ROV (3) "Victor" allows testing of the installation parameters necessary for accurate observation of earthquakes that occur locally, within the region or elsewhere throughout the globe. The project has also resulted in new developments in deep-ocean technology and skills.
Three great challenges face scientists in efforts to achieve high-quality long-term observation: resistance of instruments and cables to enormous deep-sea water pressures; resistance of instruments to corrosion in the marine environment; and perfect coherence between the equipment and the electronic systems incorporated to ensure remote control and monitoring.

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.
