ESA engineers are proposing a technique to enable a digital satellite radio service for European drivers - without the need to launch a single new satellite into orbit.
Commercial digital satellite radio is already a reality in the United States, using a costly set of dedicated satellites. The rival American services allow subscribing drivers to choose between numerous near-CD quality radio channels without tune-out or static.
Two parallel ESA studies have examined a lower-cost method of providing in-car Europe-wide satellite radio, along with supplemental text, pictures and video data. ND Satcom (prime contractor), DLR, IMST and SES Astra conducted one of the studies while Alcatel Space (prime contractor), Frauenhofer Gesellschaft, Skygate and SES Astra performed the other.
"This service would include music and voice data," said ESA engineer Rolv Midthassel from the Technology Projects Division of the Telecommunication Department. "Plus additional data could be displayed on-screen such as information on songs, traffic and weather forecasts, and other services dedicated to car drivers."

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
