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 .

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
