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."

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
