Physicists read data after storing them in atomic nuclei for 112 seconds
University of Utah physicists stored information for 112 seconds in what may become the world's tiniest computer memory: magnetic 'spins' in the centers or nuclei of atoms. Then the physicists retrieved and read the data electronically - a big step toward using the new kind of memory for both faster conventional and superfast quantum computers.

Holography with electrons
Physicists from the Max Born Institute in Berlin have now returned to the use of electrons in holography. A special element in their approach is that the electrons that image the object are made from the object itself using a strong laser.

Nanoscale X-ray tomography sheds light on origin of Earth's core
A new method of capturing detailed, three-dimensional images of minute samples of material under extreme pressures is shedding light on the evolution of the Earth's interior. Early results suggest that the early Earth did not have to be entirely molten to separate into the rocky crust and iron-rich core it has today. Researchers at Stanford University and SLAC National Accelerator Laboratory are leading the group pioneering the technique, which could lead to a wide range of new experiments.

Understanding the 'ionization surprise'
In 2009, the journal Nature Physics called it the 'Ionization Surprise'. Where it had been commonly thought that the ionization of atoms by strong laser fields was meanwhile well-understood, novel experiments where rare gas atoms were ionized using relatively long (few-micrometers) wavelength laser light suddenly revealed an unexpected and universal low-energy feature that defied explanation. Now, scientists in Germany provide an explanation.

Experts study environmental impact of silver nanoparticles in textiles
With the aim of confirming that textiles treated with silver nano-particles do not cause any harm, researchers at the Hohenstein Institute in Germany, together with 16 partners from research institutions, industry and the regulatory authorities, are working on a major project to investigate the behaviour, whereabouts and effect of the particles in the environment.

High-performance computer for simulating laser processes in nanophotonics
The simulation of laser-based production processes has to cover a wide span of time and length scales, especially in new techniques from micro- and nanophotonics. This requires special algorithms which have already been used successfully at the Fraunhofer Institute for Laser Technology ILT, as well as a massive amount of computer power. Fraunhofer ILT has built a high-performance computer cluster at the Center for Nanophotonics.
