A "Red Tide" event that occurred off the coast of El Salvador late last year directly caused the deaths of some 200 sea turtles, according to test results released today by the Wildlife Conservation Society (WCS) and other organizations.
Responding to requests from the Salvadoran government and the US Agency for International Development (USAID)for assistance, WCS veterinary pathologist Dr. Julie White journeyed to the southern coast of El Salvador in January to help determine why these ocean-going reptiles--mostly olive ridley turtles and a few green and hawksbill turtles--were dying in such high numbers. Tissues collected from dead turtles, and analyzed by both U.S. biologists and researchers from the Mexican Autonomous University, revealed the culprit: saxitoxin, which is produced by the species of algae and sea plankton that cause the phenomenon known as "Red Tide."
"The rapid response and subsequent diagnosis in this outbreak demonstrates the power of collaboration among governments and non-governmental organizations," said White, who collected tissue samples in January. "We are still testing samples from other turtles that died during this period, but we can say with some certainty that Red Tides first reported in November resulted in widespread sea turtle mortality."

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...
