• Nanosilver as an electrocatalyst for CO₂ reduction
  Via electrolysis, CO₂ can be reduced to CO, a raw material for further chemical products such as fuels. Within the GreenQuest Project, an internation team led by HZB chemist Prashanth Menezes has n...
• Natural high-performance adhesive made from mistletoe berries
  Researchers at the Technical University of Munich (TUM) have developed a high-performance adhesive whose key ingredient is extracted from mistletoe berries. The fully bio-based glue bonds materials...
• X-ray light on demand: For the first time, its frequency can be tuned continuously
  Ultrashort laser pulses can be used to generate X-rays. Normally, however, only certain specific frequencies are produced. A team from TU Wien and the University of California San Diego has now dev...
• Simple cleaning reduced bacteria on single-use medical devices
  Three simple cleaning methods reduced bacterial levels on used single-use medical devices, according to a study from the University of Gothenburg. The findings could prove useful as a last-resort m...
• AI-based method that can predict the bitterness of peptides
  During the production of fermented products such as kefir, Parmesan, or mountain cheese, as well as in the production of protein powders, bitter-tasting peptides can form, which impair the taste an...
• More Than Just Ions: What Causes Droplet Charging?
  Whether on a windowpane at home or during the industrial cleaning of computer chips: Droplets sliding over solid surfaces become electrically charged. Yet the physical mechanism behind this chargin...
• New technique could make MRI more precise
  A team of researchers at the University of Stuttgart has developed a new method that could make MRI even more precise by eliminating "dead time," a key limiting factor in the measurement process, t...
• How methanol and formaldehyde form abiotically in nature
  The biopolymer lignin - one of the most important carbon reservoirs in plants and soils - not only decays through fungi or bacteria but can also be chemically attacked by iron linked with reactive ...
• High-resolution insights into individual biomolecules and catalysts
  Very small biological samples and even individual biomolecules can now be examined under near-physiological conditions with high confidence at the BESSY II infrared beamline with a newly validated ...
• Adaptive optics enable a clearer view of biological tissue
  The Fraunhofer Institute for Photonic Microsystems IPMS has developed a new technology that can significantly improve the image quality of optical microscopes. A specially designed micromechanical ...
• Tiny particles keep water jets stable for longer
  Tiny, soft polymer particles - known as microgels - can help to stabilize extremely thin liquid jets. How this works is the finding of a study led by researchers at TU Darmstadt. The findings could...
• From strays to territory bosses: epigenetics makes cheetahs adaptable
  Cheetahs have a low genetic diversity - and are therefore poorly equipped to adapt to changing environmental conditions. Nevertheless, the animals display remarkable flexibility: over the course of...
• Capturing nanoparticles with two-frame X-ray movies
  One big dream of ultrafast science has been to watch changes in nanoparticles or biomolecules on their natural timescale. Experimentally, this can be realized by taking two snapshots of the same na...
• Faster diagnostics, deeper insights: Researchers strengthen response to Ebola outbreaks
  The current outbreak of Bundibugyo virus (BDBV) in the Democratic Republic of the Congo highlights the challenges of responding to rare but potentially devastating infectious diseases. Two studi...
• Earth's crust as a sponge
  Cold, fast-sinking tectonic plates diving deep into the Earth's interior are carrying up to one trillion kilograms water per year into the mantle, double the amount than earlier estimates suggested...
• Discovery of molecular virulence mechanism
  Pseudomonas aeruginosa is a rod-shaped, Gram-negative bacterium capable of infecting various parts of the body, including the lungs, skin, and bloodstream. It accounts for approximately 7% of hospi...
• A sustainable flame retardant derived from corn steep liquor
  Halogenated flame retardants raise environmental concerns and are considered harmful to human health. As a result, researchers have been searching for alternatives for many years. Fraunhofer re...
• Detailed insights into the oxidation processes of copper
  Before pure copper oxide builds up, complex superstructures such as '29'Cu_xO, are formed. The new results on the '29'Cu_xO superstructure have relevance for catalyst research and corrosion protectio...
• New AI model maps the ion binding sites that control how proteins work
  Researchers at Constructor University and Constructor Labs have developed BiteNetI, a deep-learning model that locates the binding sites of 14 biologically important ion types directly in three-dim...
• A search engine for single-cell RNA
  Nikolaus Rajewsky and his team have built a Google-like search engine that can scan data from millions of single cells from thousands of experiments worldwide in seconds. The tool, described in "Na...
• Gut microbes transform common herbicide into previously unknown compounds
  The human microbiome may play a critical role in determining the health impacts of chemical exposure from food, according to new research on the herbicide metazachlor. Discussions about plant pr...
• Staying one step ahead of resistance
  Antimicrobial resistance is one of the greatest challenges facing modern medicine. A new class of programmable antibiotics known as asobiotics can be used to treat bacterial infections when classic...
