Chinese scientists have brewed a way to steal -- with 80 percent accuracy -- automatic teller machine PINs by infecting wearable devices.…

The idea of a platform between two whole numbers might seem impossible to imagine. However, for someone working with fractals in math, the challenge is not so different. Fractals are used to measure things between dimensions, as in something that's more than 2-D, but not quite 3-D. A National Science Foundation mathematician created this fractal to better understand how wind would move oceanographic sensors in an eddy. This is just a snapshot in time, but wind would push the sensors back and forth, making it uncertain where they might go. Because of the stochastic nature -- a kind of organized randomness -- this fractal helps visualize the scenario and come up with an optimal control so sensors use as little battery as possible and minimize displacement.

A microbial partnership thriving in an acidic hot spring in Yellowstone National Park has surrendered some of its lifestyle secrets to researchers. The team isolated the archaeon Nanopusillus acidilobi and cultured these tiny microbes just 100 to 300 billionths of a meter in size and can now study how they interact with their host, another archaeon (Acidilobus). The relationships between these two organisms can serve as a valuable model to study the evolution and mechanisms of more complex systems.

A young Hawaiian Goose (Nene) flexing its muscles and showing off its developing feathers at WWT Slimbridge.
The nene is the world's rarest goose. The nature reserve WWT Slimbridge, in England, was instrumental in the successful breeding of Hawaiian geese in captivity. Under the direction of conservationist Peter Scott, it was bred back from the brink of extinction during the 1950s for later re-introduction into the wild in Hawaiʻi. There are still Hawaiian geese at Slimbridge today.
