A man gets lost when hiking. He is unable to tell the rescue service his exact position even though his mobile is working. Meanwhile, a pedigree dog, the apple of the owners eye, runs off. What to do these people do?
Mobile phone positioning helps locate lost people quickly and reliably. In the future, the volume of positioning services is expected to grow and their quality improve when the US GPS service is complemented by the European Galileo satellite positioning system.
However, a number of open issues remain in the utilisation of the new satellite positioning technology. Professor Markku Renfors, Head of the Institute of Communications Engineering at the University of Tampere, has led a research project exploring ways of combining various positioning technologies as economically and reliably as possible.

Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to...
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
