ScienceDaily (May 20, 2011) Scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have further boosted the energy conversion efficiency of flexible solar cells made of copper indium gallium (di)selenide (also known as CIGS) to a new world record of 18.7 percent -- a significant improvement over the previous record of 17.6 percent achieved by the same team in June 2010.

The measurements have been independently certified by the Fraunhofer Institute for Solar Energy Systems in Freiburg, Germany.

The worlds first WiFi-enabled SIM brings both new freedom and security for mobile phone users.
The flexibility of a Wireless LAN connection can now be enjoyed with any kind of mobile phone - combined with the high security of a SIM card. Sagem Orga (Safran group) and Telenor Group demonstrated numerous use cases of this ground-breaking development at the Mobile World Congress that was held in February in Barcelona, Spain.
The SIM card has always been recognized as the secure element inside a mobile phone, and according to the GSMA, it is widely deployed - in use by more than 4 billion users every day to authenticate the subscriber on a telecom network.

Though coordinating eight separate arms might seem a tricky task for an octopus brain, whats really demanding is controlling the arms flexible, infinitely variable movements. Now researchers have figured out part of their secret.

Unlike us, specific regions of an octopus motor cortex dont correspond to specific parts of its body. Instead, each region controls different parts at different times. Their motor neural network seems as flexible as their bodies a phenomenon that expands the range of neurophysiological possibility, and could refine the design of arm-flexing robots.
