Conservationists follow six-weeks old wild tigers for first time
Scientists from the Wildlife Conservation Society (WCS) and their Russian colleagues from the Sikhote-Alin Reserve have fitted three wild Siberian tiger cubs under six weeks old with tiny radio-collars, marking the youngest wild tigers to be tracked by scientists. The collars-made with an elastic designed to expand and eventually break and fall off of the growing cubs-weigh just over five ounces and would fit well on a large house cat. These devices will give researchers crucial insights into the lives of tiger cubs in the Russian Far East and ways of improving the survival and reproduction of the largest of the cat species.
"Through radio telemetry, we’ve learned a great deal about the needs of Siberian tigers, animals so elusive that few field researchers have seen them in their natural habitat," said John Goodrich, a WCS researcher and the head of the Siberian Tiger Project. "Now we can finally get some idea of what causes the deaths of tiger cubs, which suffer a mortality rate of nearly 50 percent in their first year; if we can somehow improve their chances, we can make a big difference in helping the population to grow."

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
