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 .

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
