Further development of modern information technology requires computer capacities of increased efficiency at reasonable costs. In the past, integration density of the relevant electronic components was increased constantly. In continuation of this strategy, future components will have to reach the size of individual molecules. Researchers have now come closer to reaching this target.
Polish physicists have been aiming to build an optical atomic clock, an extremely precise device with an accuracy of one second in a few dozen billion years, since 2008. The last of the three key components of the clock: an atomic frequency standard based on cold strontium atoms has just been developed. The clock itself will be assembled already this year.
(PhysOrg.com) -- A prototype robot spy "ornithopter," the Nano-Hummingbird, has successfully completed flight trials in California. Developed by the company AeroVironment Inc., the miniature spybot looks like a hummingbird complete with flapping wings, and is only slightly larger and heavier than most hummingbirds, but smaller than the largest species.
Volunteers experienced the virtual bodies as if they were their own, with possible applications in computer games or to transport people digitally to other locations
How can you plan for an emergency the nature of which you don’t know? Several Fraunhofer institutes are working on strategies and technologies that would help to predict and improve the response to crises. Their solutions are shown at the CeBIT in Hannover (March 1 – 5).
An important milestone toward the realization of a large-scale quantum computer, and further demonstration of a new level of the quantum control of light, were just accomplished.
A new technology that allows wireless signals to be sent and received simultaneously on a single channel has been developed. The research could help build faster, more efficient communication networks, at least doubling the speed of existing networks.
