Scientists film magnetic memory in super slo-mo

Researchers have used high-speed photography to film one of the candidates for the magnetic data storage devices of the future in action. The film was taken using an X-ray microscope and shows magnetic vortices being formed in ultrafast memory cells. Their work provides a better understanding of the dynamics of magnetic storage materials.

Research reveals how our bodies keep unwelcome visitors out of cell nuclei

The structure of pores found in cell nuclei has been uncovered by scientists, revealing how they selectively block certain molecules from entering, protecting genetic material and normal cell functions. The discovery could lead to the development of new drugs against viruses that target the cell nucleus and new ways of delivering gene therapies.

Cooling with the coldest matter in the world

Physicists have developed a new cooling technique for mechanical quantum systems. Using an ultracold atomic gas, the vibrations of a membrane were cooled down to less than 1 degree above absolute zero. This technique may enable novel studies of quantum physics and precision measurement devices.

Ultra-short X-ray pulses explore the nano world

Ultra-short and extremely strong X-ray flashes are used by researchers to take 'snapshots' of the geometry of tiniest structures, for example the arrangement of atoms in molecules. To improve not only spatial but also temporal resolution further requires knowledge about the precise duration and intensity of the X-ray flashes. An international team of scientists has now tackled this challenge.
