The highly endangered North Atlantic right whale population is facing a difficult journey to recovery. That recovery may become even more precarious if North Atlantic climate takes a turn for the worse, according to Cornell University ecologists.
Cornell scientists say that winter atmospheric conditions over the North Atlantic affect the abundance of zooplankton eaten by right whales, one of the most endangered species of marine mammal. New models developed by these scientists can be used to explain the relationships among climate changes, atmospheric temperatures and winds; patterns in ocean currents, water temperature and salinity; the food resources required by whales and other animals; and the reproductive success of right whales.
Details of the whale-climate studies are reported by Charles H. Greene and Andrew J. Pershing, of the Cornell Ocean Resources and Ecosystems Program, in an article entitled "Impact of Climate Variability on the Recovery of Endangered North Atlantic Right Whales" to appear in the December 2003 issue of Oceanography. Other authors of Oceanography paper are Robert D. Kenney of the University of Rhode Island and Jack W. Jossi of the National Marine Fisheries Service (NMFS). A second article, "Climate and the Conservation Biology of North Atlantic Right Whales: Being a Right Whale at the Wrong Time?" will be published in the February 2004 issue of the journal, Frontiers in Ecology and the Environment .

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.
