After 14 years without having been seen, several young scientists supported by the Conservation Leadership Programme (CLP), have rediscovered the Carrikeri Harlequin Frog (Atelopus carrikeri) in a remote mountainous region in Colombia.
The critically endangered Carrikeri Harelquin frog was recently rediscovered by the Project Atelopus team in the Sierra Nevada de Santa Marta Mountains in Colombia’s Magdalena department. Colombia is one of the world’s richest countries in amphibian diversity with more than 583 species. Unfortunately, in the past several years, there has been a decline in amphibian populations especially in higher elevations in Colombia.
“By discovering that the endangered frog still exists, we hope it will show how important conservation is,” said Luis Alberto Rueda, scientist for the Project Atelopus team who led the expedition. “And we plan to continue with our research so that we can better assist in helping to ensure that this frog will not become extinct.”
In addition to Rueda, who is part of the GECOH (Grupo de Ecofisiología, Comportamiento y Herpetologia) of the University of the Andes, the individuals who are part of the Atelopus team of scientist include: Oswaldo Cortes, Giovanni Chaves, Erika Salazar, Jose Gil, Sergio Pulido, Astrid Nossa, Fabian Tavera, Jenny Gallo, Ximena Villagrán and Nidia Rodriguez members of the Ecodiversidad Colombia Foundation (www.ecodiversidad.org).
The Carrikeri Harelquin frog is native to the Sierra Nevada de Santa Marta Mountains in Colombia’s Magdalena province. The frog lives in the páramo habitat at an attitude of 4,000 meters and is approximately five centimeters in size. This population is unique since it possesses orange markings, which are unusual for this species. Páramo is a neotropical grassland ecosystem located in high elevations between the upper forest line (about 3,100 meters in altitude) and the permanent snow line (about 5,000 meters). Nearly 57 percent of this ecosystem worldwide is found in Colombia.

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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
