• Viruses under stress: how viral shells change shape as they dry out
  When viruses travel through the air in tiny droplets, they can quickly start to dry out. Yet many viruses remain infectious after rehydration-something that is still not fully understood. Now, an i...
• Stable sensor surfaces for drug measurements in blood plasma
  Medications can save lives. Yet for some drugs, the concentration in a patient's bloodstream determines whether a treatment is effective or whether harmful side effects may occur. Researchers...
• Virtual 3D tissue staining: Non-destructive analysis of pathological changes
  Rudolf Virchow fundamentally changed medicine when he formulated his cell theory of disease in the 19th century: diseases do not arise inexplicably within the organism, but rather in specific cells...
• Keratin - A multifunctional filler for coatings
  A cost-effective and multifunctional filler for paints and coatings could be obtained from chicken feathers in the future: keratin. Researchers at two Fraunhofer Institutes have achieved promising ...
• Artificial intelligence evaluates chemical spectra in minutes
  Determining which substance has actually been produced in a test tube or flask is one of the central tasks of chemistry. Particularly in the case of complex or novel compounds, however, this can be...
• Observation of living cells solves mystery of bacterial cell division
  In the life sciences, bacteria are currently studied not only as pathogens or, conversely, as valuable symbionts of multicellular life, but they are also suitable as simple model organisms for inve...
• Entirely new way of making espresso unveiled
  Researchers at UNSW Sydney have harnessed the power of ultrasonic sound waves to make espresso-strength coffee with room temperature water, cutting energy use by up to 75%. That morning coffee k...
• A new route to safe and sustainable synthetic chemistry
  Oxidation reactions are indispensable to the chemical industry, but from a process safety perspective they are among the most challenging transformations. A research team at the University of B...
• New route to sustainable energy storage: an all-water supercapacitor
  Can pure water store electrical energy? A research team led by Dr. Vasily Artemov within the Cluster of Excellence "BlueMat - Water-Driven Materials" at Hamburg University of Technology has now sho...
• How wax moth larvae can help reduce animal testing in research
  Researchers at the Helmholtz Institute for One Health (HIOH) have demonstrated that larvae of the greater wax moth (Galleria mellonella) are suitable as an alternative infection model for investiga...
• Detecting food fraud with quantum sensing
  Verifying food authenticity directly at the point of sale. This is the vision driving the partners behind the collaborative project QSPEC. Their goal is to harness quantum mechanical effects for a ...
• New antibiotics discovered to treat multi-resistant germs
  A research team involving the University of Hamburg has discovered a new active substance in a soil bacterium that has already been extensively studied. The antibiotic identified, 'manikomycin'...
• The hidden roughness of sapphire surface
  Sometimes geometry determines what is chemically possible: As TU Wien has now shown, tiny irregularities can completely change the chemical behavior of a surface. Why do certain surfaces behave...
• Antibiotics for common sore throats have very limited effect on Strep spread
  Antibiotics for sore throats have hardly any preventive effect against serious streptococcal infections in the population, according to a study from the University of Gothenburg. Instead, healthcar...
• Mobile device for high-precision measurement of air pollutants
  The UV dual-comb spectrometer detects harmful gases with unrivalled accuracy and sensitivity. The compact design allows mobile use for monitoring air quality with a range of several kilometres. ...
• A 50-year-old mystery has been solved: how acid removes water from proteins
  Proteins systematically lose their protective hydration shell when their environment becomes more acidic. Until recently this was just a theory. State-of-the-art imaging techniques have helped rese...
• Ultrafast microscopy method for optical processes
  An extremely fast microscopy method to research the interaction of light and matter makes it possible to study optical processes on very short timescales. To this end, a German-Italian research tea...
• Perfect randomness realised for the first time
  Researchers at ETH Zurich have, for the first time, created certifiably perfect random numbers using a quantum experiment. These can be used, for instance, for encrypting messages. Creating per...
• Progress and representative applications of double-comb spectroscopy
  Atoms and molecules are the fundamental building blocks of matter. Spectroscopy identifies and quantifies chemical species through the unique spectral fingerprints they imprint on light. Spectr...
• Targeted binding and release of bioactive compounds
  A research team at the Leibniz Institute for Natural Product Research and Infection Biology (Leibniz-HKI) in Jena has successfully biosynthesized a natural product containing a reactive chemical gr...
• The structure of water: Entropy determines whether ions stick
  Water molecules are constantly in motion, but on average they can form preferred patterns of order. TU Wien has now shown that this has a major influence on charged particles, for example in electr...
