In 1989 researchers realized that frogs were dying around the world. Then they identified the cause: a fungal disease called chytridiomycosis. In 2004 Karen Lips, associate professor at the University of Maryland, sounded the alarm that the disease was devastating highland frogs in Central Panama and spreading across the country to the east.
"We are working as hard as we can to find and identify frogs before the disease reaches them, and to learn about a disease that has the power to ravage an entire group of organisms," said Roberto Ibanez, research scientist at STRI and local director of the Panama Amphibian Rescue and Conservation Project.
Since 2005 research institutions and zoos from Panama and the United States have scrambled to collect healthy frogs east of the infected area—to save them from extinction. The Panama Amphibian Rescue and Conservation Project unites eight institutions including STRI and the Smithsonian's National Zoological Park, along with Panama's environmental authority, ANAM, in a new effort to raise captive frogs in Panama at Summit Nature Park with support from the El Valle Amphibian Conservation Center.
In 2008, researchers first detected the fungus to the east of the Panama Canal. During a collecting trip in November 2009 to Chagres National Park, even further to the east, researchers were dismayed to find that most of the frogs there were already infected and dying.
On May 20, researchers from the PARC project returned to what they hope are still fungus-free, healthy frog habitats in Darien Province. On an earlier trip organized by members of Eldredge Bermingham's lab at the Smithsonian, another new frog species was collected by researchers from STRI, the University of Panama and the Círculo Herpetológico de Panamá.
Its name is based on ADN, the acronym for the Spanish acido deoxiribonucleico, meaning deoxyribonucleic acid, DNA, in English. "We chose this name to underscore the usefulness of genetic techniques as we identify these new frog species and determine the relationships between tropical frogs that may look very similar," said Andrew Crawford, professor at University of the Andes and research associate at STRI.
These two reports bring the total number of frog species described in Panama and Costa Rica to 197. Nearly 15 percent of these new frogs have been described in the past seven years.
The species collection and identification work was supported by Sigma Xi, the American Society of Ichthyology and Herpetology Gaige Fund, Idea Wild, the U.S. National Science Foundation, the Bay and Paul Foundation and the Smithsonian Institution. Both publications credit Panama's ANAM for research and collecting permits.
STRI, headquartered in Panama City, Panama, is a unit of the Smithsonian Institution. The institute furthers the understanding of tropical nature and its importance to human welfare, trains students to conduct research in the tropics and promotes conservation by increasing public awareness of the beauty and importance of tropical ecosystems.

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...
