"This paper provides a remarkable surprise: the Nile crocodile is not a single species, as previously thought, but instead demonstrates two species - living side-by side - constitute what has been called the Nile croc." Said Marlys Houck, geneticist with San Diego Zoo Global's Institute of Conservation Research.
"Even more remarkably, they are not each other's closest relatives; one is more closely related to New World crocodilians. The cryptic Crocodylus suchus is a unique entity worthy of a conservation strategy separate from the Nile crocodile populations of East and southern Africa."
The study, published in the October issue of Molecular Ecology, provides important information about a species that is not only an important historical icon but also critically endangered. Recent survey efforts indicate that Crocodylus suchus is declining or extirpated throughout much of its distribution. Conservationists feel that without proper recognition of this species, current sustainable use-based management policies for the Nile crocodile may do more harm than good.
The San Diego Zoo Institute for Conservation Research is dedicated to generating, sharing and applying scientific knowledge vital to the conservation of animals, plants and habitats worldwide. The work of the Institute includes onsite research efforts at the San Diego Zoo and the San Diego Zoo Safari Park (historically referred to as Wild Animal Park), laboratory work at the Arnold and Mabel Beckman Center for Conservation Research, and international field programs involving more than 235 researchers working in 35 countries.
In addition to the Beckman Center for Conservation Research, the Institute also operates the Anne and Kenneth Griffin Reptile Conservation Center, the Frozen Zoo® and Native Seed Gene Bank, the Keauhou and Maui Hawaiian Bird Conservation Centers, Cocha Cashu Biological Research Station and the Desert Tortoise Conservation Center. The Zoo also manages the 1,800-acre San Diego Zoo Safari Park, which includes a 900-acre biodiversity reserve, and the San Diego Zoo. The important conservation and science work of these entities is supported in part by The Foundation of the Zoological Society of San Diego.

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
