Electrically Modulated Light Antenna Points the Way to Faster Computer Chips
Physicists from Würzburg present a nanometre-sized light antenna with electrically modulated surface properties - a breakthrough that could pave the way for faster computer chips. Today's computers reach their physical limits when it comes to speed. Semiconductor components usually operate at a maximum usable frequency of a few gigahertz - which corresponds to several billion computing operations per second.

Local Solvation is Decisive for Fluorescence of Biosensors
Nanotubes can serve as biosensors. They change their fluorescence when they bind to certain molecules. Until now, it was unclear why. Researchers have gained new insights into the cause of the fluorescence. Researchers from Bochum and Texas have discovered why carbon nanotubes fluoresce when they bind to certain molecules.

Simple diagnostics for common diseases
A new combination of single infrared light measurement and machine learning can be used to detect metabolic disorders and high blood pressure Some common diseases could be easier and quicker to diagnose in future. A team from the Max Planck Institute of Quantum Optics, the Ludwig Maximilian University of Munich and the Helmholtz Zentrum München has demonstrated in a representative study that infrared light measurements of blood plasma when combined with machine learning can be used to detect various metabolic disorders such as type-2 diabetes and high blood pressure.

Glimpse into the nanoworld: microscope reveals tiniest cell processes
Research team including Göttingen University develops high-resolution fluorescence microscope What does the inside of a cell really look like? In the past, standard microscopes were limited in how well they could answer this question. Now, researchers from the Universities of Göttingen and Oxford, in collaboration with the University Medical Center Göttingen (UMG), have succeeded in developing a microscope with resolutions better than five nanometres (five billionths of a metre).

’Laser view’ into the avocado: New method reveals cell interior
Research team at the University of Göttingen develops method for recognizing cell properties Can you tell whether an avocado is hard or soft by looking at it? You would have to recognize how the plant cells behave behind the skin. The same applies to all other cells on our planet: Despite more than 100 years of intensive research, many of their properties remain hidden inside the cell.

Researchers control electronic properties of moiré crystals
Team led by physicist Ursula Wurstbauer demonstrates collective behaviour of electrons in two-dimensional crystals for the first time If you make a material thinner and thinner, there comes a point when it undergoes a seemingly miraculous transformation: A two-dimensional material that consists of only one or two layers of a crystalline solid sometimes takes on completely different properties than the same material with greater thickness.

Super-Jupiter
An image of the the James Webb Space Telescope shows the oldest and coldest known exoplanet Using the James Webb Space Telescope, a team of astronomers led by the Max Planck Institute for Astronomy imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun.

New insights into molecular mechanisms of cholera infection
Researchers investigate the strong interaction of cholera toxin with a key ganglioside on the surface of intestinal cells Cholera infections caused by Vibrio cholerae bacteria can be life-threatening and the trigger is the cholera toxin produced by the bacteria. It binds to the surface of intestinal cells - more precisely, to certain "sugar lipids" (GM1 gangliosides, GM1) on the cell surfaces.

Producing Hydrogen and Fertilizer at The Same Time
This new concept could allow the needs of previously separate industries to be combined. A research team from the University Alliance Ruhr, Germany, has found a catalyst that can be used to convert ammonia into the energy carrier hydrogen and the fertilizer precursor nitrite. The production of hydrogen and the production of fertilizer have so far been separate chemical processes.
