An international team of scientists is currently evaluating sediment cores collected during the Arctic Coring Expedition, ACEX, conducted under the auspices of the Integrated Ocean Drilling Program (IODP). ACEX, conducted in August and September this year, is an exploration success story. At a press conference in the University of Bremen, Germany, today (16 November 2004) the co-chief scientists of the expedition described the first results from this expedition.
Scientists from ten countries gathered in Bremen over the last two weeks. They analyzed sediment cores from 430 metres beneath the Arctic Ocean sea-floor. These cores reveal new insights into the past climate of the Arctic. Preliminary results show that the ACEX recovered the first ever climate record of the Arctic Ocean over the past 56 million years. Co-chief scientists Kate Moran, University of Rhode Island, and Jan Backman, Stockholm University, described key findings.
The Arctic Ocean was frozen much earlier than previoulsy thought. Professor Moran said that “we are trying to define the exact time when ice appeared but it seems clear that perennial ice existed as early as 15 million years ago”. Professor Jan Backman added that these results would become more precise over the next few months and “we have cores that will hopefully allow us to distinguish between seasonal (winter only) ice and perennial ice”.

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.
