Fraunhofer IIS presented the first DRM chip design for car radios. This car radio solution will enable drivers to select their preferred radio program from hundreds of different radio stations. However, it is something more than purely listening to favorite music: the new radio formats offer multilingual support to ethnic news or talk programs. In this way, drivers will get local news or may listen to programs in foreign languages – at any time and any place.
With the international CES exhibition in Las Vegas on January 6 - 9, 2005, the vision of Digital Radio Mondiale DRM car radios got one step closer to reality. Based on Philips‘ ”SAF7730” digital car radio platform, Fraunhofer Institute for Integrated Circuits IIS presented the first DRM implementation that seamlessly fits into today’s car radios. For the OEM, upgrading to the international DRM standard is just a matter of inserting a ”DRM module” into an existing connector slot. Initially, the ”DRM module” upgrade allows to differentiate products with minimum investment, risk and time to market. In the next stage, the evolving road maps with fully integrated ”DRM car radio chip sets” will lower the system cost further, completely inline with the requirements of the mass market.
The DRM standard applies the latest advanced audio coding algorithms for music and speech transmission – to provide FMlike sound quality at very limited bandwidth. DRM programs are digitally transmitted and highly compressed. Therefore, they may be stored on-the-fly in the car radio’s memory, to build up a personal music collection. In addition, DRM programs carry other types of multimedia content and information, including headline news or traffic and tourist information. This data is transmitted in the background and will be immediately available after one gets into the vehicle.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
