When researchers and policymakers consider the best ways to protect an endangered species, the phrase "best available science" is frequently used to describe the scientific basis behind decisions that are aimed at preserving natural habitat and preventing further decline in species population.
Marcella Kelly, assistant professor of wildlife science at Virginia Tech, has provided a photo of a puma taken in Belize in 2003 from a remote camera, part of her research to measure populations of big cats.
However, the "best available science" has been shortchanging the Florida panther, according to an article by Liza Gross in the Pulbic Library of Science Biology (Aug. 23, 2005) and a report to be published in the January 2006 issue of the Journal of Wildlife Management (Beier P, Vaughan M, Conroy M, Quigley H. "Deconstructing flawed scientific inferences about the Florida panther.").
Since 2002, fisheries and wildlife science professor Mike Vaughan has been one of four members of a Science Review Team put in place to review the research of the State of Florida and the U.S. Fish and Wildlife Service (FWS) on one of the countrys most endangered species: the Florida panther. As a team member and an expert on large carnivore ecology, Vaughan reviewed more than 20 years and 3,000 pages of scientific literature based on Florida panther research.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
