Research team at the University of Freiburg reveals hidden particle interactions at the cell surface
Ultra-smooth interactions can be detected through high-speed measurement and frequency analysis Is it possible that in most measurements in the field of life sciences, important interactions remain hidden inside the cell or at the cell surface?  This question has puzzled the team of laserand bio-physicist Alexander Rohrbach from the University of Freiburg for years.

Researchers visualise activity of CRISPR genetic scissors
Researchers visualise activity of CRISPR genetic scissors
Scientists at Leipzig University, in collaboration with colleagues at Vilnius University in Lithuania, have developed a new method to measure the smallest twists and torques of molecules within milliseconds. The method makes it possible to track the gene recognition of CRISPR-Cas protein complexes, also known as -genetic scissors-, in real time and with the highest resolution.

Evaporative Cooling of Anions
Evaporative Cooling of Anions
Physicists from Heidelberg and Innsbruck develop technique for cooling negatively charged molecules Molecular anions, negatively charged molecules, are difficult to cool due to their specific electronic configuration. A team of physicists led by Matthias Weidemüller from Heidelberg University's Institute for Physics and Roland Wester from the Department of Ion Physics and Applied Physics at the University of Innsbruck (Austria) have now developed a new method for cooling molecular anions to below three Kelvin, i.e. approximately minus 270 degrees Celsius, in a short time.

Chemists develop new method for water splitting
Chemists develop new method for water splitting
Photocatalytic process enables water to be activated Hydrogen is seen as an energy source of the future - at least, when it is produced in a climate-friendly way. Hydrogen can also be important for the production of active ingredients and other important substances. To produce hydrogen, water (H2O) can be converted into hydrogen gas (H2) by means of a series of chemical processes.

Cell's form can be reversed
Cell’s form can be reversed
Light-switchable molecules in membranes enable different forms of living cells to be studied Membranes fulfil a variety of tasks in living cells: for example, they separate the cells from their surroundings and thus protect them. Also, by means of transport proteins they convey the necessary nutrients to the interior.

Repelling disorder: What makes cholesterol-containing surfaces so repulsive?
News from Living organisms use powerful physical principles to control interactions at their surfaces. Researchers at the Leibniz Institute of Polymer Research Dresden, Leipzig University and TU Dresden have now discovered why cholesterol-containing surfaces can exhibit greatly reduced attachment of proteins and bacteria.

A Model for Stopping Heavy Ions
Heidelberg physicists make new predictions about the collision of heavy ions at very high relativistic energies When two heavy ions collide at very high relativistic energies, they penetrate one another, during which they become excited and are slowed down. This "stopping" process can be generated experimentally, as demonstrated on the Large Hadron Collider (LHC) at Europe's CERN research centre in Geneva (Switzerland).

Nonadiabatic tunneling is crucial for understanding high harmonic generation from semiconductors
Scientists reveal that nonadiabatic tunneling is crucial for understanding high harmonic generation from semiconductors When matter is exposed to highly intense electromagnetic radiation, nonlinearities of the material may lead to the emission of light that contains very high multiples of the incident frequency.

Let information flow faster - with light instead of electricity
Let information flow faster - with light instead of electricity
Either 1 or 0. Either current flows or it does not. In electronics, everything is controlled via the binary system. Electrons already generate information quite fast and well, pass them on and take over various switching functions. But it can be done even faster. Paul Herrmann and Sebastian Klimmer from the Friedrich Schiller University of Jena have proven that.

ToCoTronics Extended
The Collaborative Research Centre ToCoTronics in condensed matter physics will be extended for four more years. The German Research Foundation is funding it with 12 million euros. Topological materials are intensively investigated in the world. This boom started at Julius-Maximilians-Universität (JMU) Würzburg, where the physics professor Laurens Molenkamp realized the first topological insulator in 2007.
