A team of scientists headed by Professor Ingo Krossing from the Department of Inorganic Chemistry at the University of Freiburg has succeeded in significantly increasing classic reagents' potential for oxidation. A team of scientists headed by Professor Ingo Krossing , Professor of Molecular and Coordination Chemistry at the University of Freiburg's Institute of Inorganic and Analytical Chemistry, has succeeded in significantly increasing the potential for oxidation of  and  positive ions.

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.

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.

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).

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.

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.

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.

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.

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.

An international team of researchers, including some from the University of Bonn, has demonstrated an exotic quantum state of matter How can a structure hold together if its individual components are actually repelling one another? An international research team has now demonstrated one example of such a highly excited exotic quantum state of matter.

Study provides new insights into the gravitational interactions between colliding black holes and answers to fundamental questions in physics. Under the leadership of Jan Plefka from the Department of Physics at Humboldt-Universität zu Berlin (HU), an international team has described the dynamics of colliding black holes with unprecedented mathematical precision.

An international team of researchers visualises atomic interactions in the protein structure called photosystem II and thus uncovers fundamental biochemical processes. Using cryo-electron microscopy a team of scientists from Humboldt-Universität zu Berlin (HU), the Swedish universities of Umeå and Uppsala and the University of Potsdam has succeeded in visualising atomic structures at an unprecedented resolution at the nanometre level underlying the process of photosynthesis.

Researchers discover an iron-containing material in the outer enamel of rodent teeth that could also make human teeth more resistant   Rodents such as beavers, nutrias (coypu) , squirrels and rats have particularly strong, elongated front teeth that grow continuously over the course of their lives. Using state-of-the-art imaging techniques, researchers at the Max Planck Institute for Solid State Research in Stuttgart have now elucidated the tooth structure of various rodent species at the nanometre scale.

A study by the University of Bonn gives novel insight into properties which are often difficult to observe Thousands of particles of light can merge into a type of "super photon" under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers at the University of Bonn have now shown that this exotic quantum state obeys a fundamental theorem of physics.

In the search for signals from the early universe, the Heidelberg scientist Georg Wolschin deals with the question of whether and how residual spectral lines from the recombination phase with the formation of the first elements can be detected in the cosmic background radiation - which can be measured very precisely today.

A research team from Bochum has identified a crucial detail that's essential for the production of hydrogen using biocatalysts. Under certain conditions, some algae are able to produce hydrogen - a much sought-after green energy source. Its production takes place in the unique catalytic center of the unicellular algae and is only possible if certain cofactors of the relevant proteins are present.

ESA's space telescope reveals secrets of the cosmos. University of Bonn is involved Today, the Euclid Consortium publishes the first scientific publications on observations with the Euclid space telescope. In a first early observation phase, some scientifically spectacular results have already been achieved.

  Observations made by the Euclid telescope show the world the discovery of free-floating new-born planets, of a new dwarf galaxy and many more.

New scientific data from the Euclid Space Telescope reveals the mystery of the faint glow in the Perseus galaxy cluster The Perseus galaxy cluster was one of the first targets of ESA's Euclid space telescope. It contains thousands of brilliant galaxies, as heavy as 650 trillion suns, held together by their own gravity.
