The Centre for Telecommunications Value-chain Research (CTVR) has been awarded the world’s first software-radio test licence. The licence will be used to investigate and develop more flexible ways of communicating to mobile devices, including ‘thinking radios’ and other cutting-edge communications systems.
Radio frequencies are valuable assets - particularly for mobile phone operators who have paid huge sums for them in the past – and as a result are very tightly regulated. Yet despite their commercial value, many parts of the frequency spectrum are under-utilised.
To investigate and develop products that can take advantage of these unused frequencies, researchers require access to frequency bands, a means of sensing current usage and a flexible system that can hop between the available bands. Science Foundation Ireland-backed CTVR already has the required software, so the awarding of the licence by ComReg opens up tremendous commercial opportunities, explained CTVR director, Professor Donal O’Mahony.

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...
