• A more climate-friendly alternative for Haber-Bosch process
  Like in the Garden of Eden: Grain, beets, and potatoes should sprout as luxuriantly as possible so that plates are well filled. This is ensured by regular fertilization-especially with nitrogen. A ...
• Molecular mechanism uncovered: Beta-Carotene keeps enzymes active under heavy load
  Enzymes are vital to metabolism and drive countless biological processes in humans, plants, and industry. Yet, when overwhelmed by excess substrate, some enzymes slow down - a phenomenon known as s...
• Advancing protein simulation with machine learning
  An international team led by Einstein Professor Cecilia Clementi in the Department of Physics at Freie Universität Berlin introduces a breakthrough in protein simulation. The study, published in Na...
• Sustainable synthesis of biomolecules and pharmaceuticals
  In the future, it may be possible to produce bioactive molecules and pharmaceuticals without relying on expensive enzymes or toxic metals as external catalysts. Chemists at Friedrich-Alexander-Univ...
• On the scalable production of gold from fusion reactors
  Marathon Fusion has announced a solution to the millennia-old grand challenge of alchemy: the transmutation of gold. Unlike previous attempts, our method is massively scalable, pragmatically achiev...
• How to determine the amount of microplastic in seafood
  How much microplastic truly ends up in the seafood on our plates? The answer varies significantly because there are no standardised analytical procedures in food monitoring to quantify the amount o...
• Mapping the metabolism of blood stem cells
  Researchers from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and ETH Zürich have created the first integrated map detailing the metabolic and molecular changes in human bl...
• Study analyzes 400 million years of enzyme evolution
  Enzymes catalyze chemical reactions in organisms - without which life would not be possible. Leveraging AlphaFold2 artificial intelligence, researchers at Charité - Universitätsmedizin Berlin have ...
• New kind of laser deveolped
  Researchers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), opens an external URL in a new window and TU Wien (Vienna, Austria) have invented a new type of tunable...
• Authentication of additively manufactured components using their microstructural fingerprint
  In the field of additive manufacturing, the ability to uniquely identify and authenticate parts is crucial for certification, logistics, and anti-counterfeiting efforts. This study introduces a nov...
• Producing Desired Epoxides from Pollutants
  Doctoral students at Ruhr University Bochum have described a new selective biocatalyst in an interdisciplinary and inter-university collaboration with Heinrich Heine University Düsseldorf. New b...
• Check the sustainability of chemicals easily online with ChemSelect
  Various substances are available for a wide range of chemical applications. These substances can have very different effects on humans and the environment. ChemSelect is a freely available web a...
• New Dynamics Discovered in Heterogeneous Catalysis
  Oxygen evolution is considered one of the most energy-intensive steps in water electrolysis and is therefore a key factor for more efficient green hydrogen production. Modelling of the reaction mec...
• The oldest ice core on Earth at the Alfred Wegener Institute
  A unique ice core is currently being examined in the Alfred Wegener Institute's ice laboratory: the oldest continuous ice core that has ever been drilled on Earth. As part of the EU-funded Beyond E...
• The Arctic Ocean was never completely frozen - not even during the Ice Ages
  For years, scientists have debated whether a massive, kilometre-thick ice shelf once covered the entire Arctic Ocean during the coldest phases of the Ice Ages. A new study, now published in Science...
• How to kill 'zombie' TB cells resistant to antibiotics
  Many dangerous pathogens, including the bacteria that cause TB, are capable of generating dormant, drug-tolerant cells often described as 'zombies'. These persister cells can survive intense antibi...
• On the trail of plastic
  The ALKOR expedition AL635 led by GEOMAR Helmholtz Centre for Ocean Research started in the western Baltic Sea, in the German-Danish border area. The aim of the expedition is to systematically reco...
• Sustainable foams: Cellulose instead of crude oil
  Foams have numerous possible potential applications, for example ranging from the automotive, household and mechanical engineering sectors to leisure and sports applications. Until now, it has been...
• Microbes transform plastic waste into paracetamol
  Paracetamol production could be revolutionised by the discovery that a common bacterium can turn everyday plastic waste into the painkiller, a study reveals. The new method leaves virtually no ...
• The bacterial use of biomass with potential for biofuels and new antibiotics
  The elucidation of the structure and origin of the so-called "Yellow Affinity Substance" (YAS) provides new insights into cellulose degradation by the bacterium Clostridium thermocellum (new name: ...
• Unmasking hazardous compounds in cosmetics, skincare products and perfumes
  Lifestyle products contain hazardous compounds that have not been detected by previous tests and are not currently regulated. This was demonstrated by scientists from Justus Liebig University Giess...
• Rethinking catalysis - from tradition to the future
  Dr. Josep Cornella has been appointed Director of the Max-Planck-Institut für Kohlenforschung in Mülheim an der Ruhr. From April 1st, the 40-year-old chemist joins the board of directors as the 6th...
• When Electrons "Jump" into Water: The Secret Behind High Electrode Capacities
  In order to develop improved electrolysers for regenerative hydrogen production, the processes on the surfaces of the metal electrodes used must be precisely understood. Researchers from the Theory...
