Unknown Population of Stars Discovered
Unknown Population of Stars Discovered
Near the centre of the Milky Way there exists a heretofore unknown population of stars that exhibits characteristic properties. It was discovered by an international research team under the direction of Dr Manuel Arca Sedda of Collaborative Research Centre "The Milky Way System" (CRC 881) of Heidelberg University.

Sun model completely confirmed for the first time
Sun model completely confirmed for the first time
Borexino detector succeeds in measuring the sun's CNO fusion cycle The Borexino Experiment research team has succeeded in detecting neutrinos from the sun's second fusion process, the Carbon Nitrogen Oxygen cycle (CNO cycle) for the first time. This means that all of the theoretical predictions on how energy is generated within the sun have now also been experimentally verified.

Detecting bacteria with fluorescent nanosensors
Luminous carbon nanotubes detect pathogens - and are quick and easy to use. Researchers from Bochum, Göttingen, Duisburg and Cologne have developed a new method for detecting bacteria and infections. They use fluorescent nanosensors to track down pathogens faster and more easily than with established methods.

Controlling fully integrated nanodiamonds
Controlling fully integrated nanodiamonds
Using modern nanotechnology, it is possible nowadays to produce structures which have a feature sizes of just a few nanometres. This world of the most minute particles - also known as quantum systems - makes possible a wide range of technological applications, in fields which include magnetic field sensing, information processing, secure communication or ultra-precise time keeping.

Ultrathin nanomesh sensor to measure sense of touch
World's first fingertip-mounted sensor that maintains user's sensitivity Scientists from the Technical University of Munich (TUM) and the University of Tokyo have developed an ultrathin pressure sensor that can be attached directly to the skin. It can measure how fingers interact with objects to produce valuable data for technological or medical applications.

Surprises in 'active' aging
Surprises in ’active’ aging
Physicists from the University of Göttingen use computer simulation to investigate aging in living glassy systems Aging is a process that affects not only living beings. Many materials, like plastics and glasses, also age - ie they change slowly over time as their particles try to pack better - and there are already computer models to describe this.

Metal-organic frameworks become flexible
Metal-organic frameworks become flexible
Combined efforts of experiment and simulation pave the way to new applications Materials consisting of inorganic and organic components can combine the best of two worlds: under certain circumstances, the so-called MOFs - short for metal-organic frameworks - are structured in the same order as crystals and are at the same time porous and deformable.

How nitrogen is transferred by a catalyst
Chemists at the University of Göttingen and Goethe University Frankfurt characterise key compound for catalytic nitrogen atom transfer Catalysts with a metal-nitrogen bond can transfer nitrogen to organic molecules. In this process short-lived molecular species are formed, whose properties critically determine the course of the reaction and product formation.

Understanding the spread of infectious diseases
Understanding the spread of infectious diseases
Scientists worldwide have been working flat out on research into infectious diseases in the wake of the global outbreak of the COVID-19 disease, caused by the new coronavirus SARS-CoV-2. This concerns not only virologists, but also physicists, who are developing mathematical models to describe the spread of epidemics.

Novel Photoresist Developed
Researchers in the -3D Matter Made to Order- Cluster of Excellence expand possibilities of three-dimensional printing of the tiniest microstructures Researchers of Karlsruhe Institute of Technology (KIT) and Heidelberg University have developed a novel photoresist for two-photon microprinting. For the first time, it can be used to produce three-dimensional microstructures with cavities in the nano-range.

Smart bottle brushes
Smart bottle brushes
Neutrons make structural changes in molecular brushes visible They look like microscopic bottle brushes: Polymers with a backbone and tufts of side arms. This molecular design gives them unusual abilities: For example, they can bind active agents and release them again when the temperature changes. With the help of neutrons, a research team from the Technical University of Munich (TUM) has now succeeded to unveil the changes in the internal structure in course of the process.

Molecular swarm rearranges surface structures atom by atom: New study
Molecular swarm rearranges surface structures atom by atom: New study
Much like a zipper, carbene molecules cooperate on a gold surface to join two rows of atoms into one row, resulting - step by step - in a new surface structure. The surface of metals plays a key role in many technologically relevant areas, such as catalysis, sensor technology and battery research. For example, the large-scale production of many chemical compounds takes place on metal surfaces, whose atomic structure determines if and how molecules react with one another.

Stellar explosion in Earth's proximity
Stellar explosion in Earth’s proximity
Discovery of iron-60 and manganese-53 substantiates supernova 2.5 million years ago When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova - a stellar explosion that could also cause damage on Earth. While Betelgeuse has returned to normal, physicists from the Technical University of Munich (TUM) have found evidence of a supernova that exploded near the Earth around 2.5 million years ago.

The Return of the Spin Echo
The Return of the Spin Echo
If the spins of phosphorus atoms in silicon are cleverly excited with microwave pulses, a so-called spin echo signal can be detected after a certain time. Surprisingly, this spin echo does not occur only once, but a whole series of echoes can be detected.
