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.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
