Emerging wireless technologies for vehicle-to-vehicle communication promise to dramatically reduce fatal roadway accidents by providing early warnings to motorists. As well as improving road safety, such technologies will also help optimise traffic flow and enable drivers to take greater control of their vehicles.
This is the broad vision behind the IST-funded project CarTALK 2000. The project developed cooperative driver assistance systems and a self-organising ad-hoc radio network with the aim of preparing a future standard. Dr Christian Maihöfer of DaimlerChrysler and coordinator of CarTALK 2000 believes that such technology will have a vital role to play in saving lives in the future.
“If we want to achieve the goal of improved road safety and significantly reduce the number of road fatalities, local sensors alone will not be able to fully achieve this goal. Therefore the idea is for sensor information and information about manoeuvres to be transmitted from one car to other cars in the vicinity. This allow early reactions like braking if some vehicles in front have had to use emergency braking and helps to prevent rear end collisions,” he says.

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...
