Scientists from the Universities of Sheffield and Leeds will soon be able to study some of the most elusive particles known to man, thanks to a giant telescope under the sea that looks down towards the centre of the Earth rather than up into the sky.
Together with fellow scientists from across Europe they are building a telescope 2400m (one and a half miles) under the Mediterranean Sea to detect neutrinos. These tiny elementary particles hardly exist at all, having no charge and almost no mass. Neutrinos zoom through the earth at almost the speed of light, travelling here from some of the most extreme regions of the cosmos. Understanding them will give us a new view of the Universe and may allow scientists to confirm the existence of dark matter. Dark matter is believed to make up some of the 90 per cent of the missing mass of the Universe that has never been detected.
The project, costing 20 million Euros, is the result of collaboration between 150 physicists and astronomers from sixteen European organisations.

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...
