• Observing individual atomic collisions during diffusion
  In the world of research, diffusion is understood as a process in which tiny particles uniformly disperse throughout a gas or liquid. Although these media are made up of individual particles, diffu...
• How CRISPR proteins find their target
  UC Berkeley researchers have discovered how Cas1-Cas2, the proteins responsible for the ability of the CRISPR immune system in bacteria to adapt to new viral infections, identify the site in the ge...
• 3-D imaging of surface chemistry in confinement
  EPFL researchers have developed an optical imaging tool to visualize surface chemistry in real time. They imaged the interfacial chemistry in the microscopically confined geometry of a simple glass...
• A plastic planet - Production, use, and fate of all plastics ever made
  More than 8 billion metric tons. That's the amount of plastic humans have created since the large-scale production of synthetic materials began in the early 1950s. It's enough to cover the entire c...
• Innovative nanosensor for disease diagnosis
  Breath pattern recognition is a futuristic diagnostic platform. Simple characterizing target gas concentrations of human exhaled breath will lead to diagnose of the disease as well as physical cond...
• Fresh role for nitric oxide uncovered
  Cornell University chemists have uncovered a fresh role for nitric oxide that could send biochemical textbooks back for revision. They have identified a critical step in the nitrification proces...
• Self-disposing supramolecular materials with a tunable lifetime
  Materials that assemble themselves and then simply disappear at the end of their lifetime are quite common in nature. Researchers at the Technical University Munich (TUM) have now successfully deve...
• Introducing nano antibodies into living cells
  Scientists at the Technische Universität Darmstadt, Ludwig Maximilians University (LMU) Munich and the Leibniz Institute for Molecular Pharmacology (FMP) have managed to introduce tiny antibodies i...
• Measuring the half-life of RNA molecules
  RNA molecules are individual transcripts of the cell's DNA. They transfer the genetic information of the DNA and provide a template for the production of proteins that regulate all the cell's proce...
• Reviewing safety of glutamates added to food
  EFSA has established a safe intake level for glutamic acid and glutamates used as food additives after re-evaluating their safety. The Authority also concluded that estimated dietary exposure to gl...
• Study paves the way to investigate nano-machines in action
  A team of scientists has used microwaves to unravel the exact structure of a tiny molecular motor. The nano-machine consists of just a single molecule, made up of 27 carbon and 20 hydrogen atoms (C...
• New method for quicker identification of environmental toxin benzopyrene
  Summertime is barbecue time. However, when fat reacts with glowing coal, a substance chemists call benzopyrene is created. It is a widespread environmental toxin that can cause cancer in humans. Si...
• A precise new way to study materials using X-ray free-electron laser
  Scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have made the first direct measurements, and by far the most precise ones, of how electrons mov...
• Antioxidants against sepsis
  During sepsis, cells are swamped with reactive oxygen species generated in an aberrant response of the immune system to a local infection. If this fatal inflammatory path could be interfered, new t...
• Black phosphorus and its new potential
  When it was discovered over a century ago, black phosphorus was considered relatively useless. Over the past five years, however, the engineers and chemists have become intrigued by the material fo...
• Viruses over antibiotics: Determining the 3D structure of phages
  Phages have become a focus of research in the battle against antibiotic resistance. These bacteria-eating viruses have already proven effective in experiments against multidrug-resistant bacteria. ...
• Endocrine disruptors: major step towards protecting citizens and environment
  Member States representatives voted in favour of the European Commission's proposal on scientific criteria to identify endocrine disruptors in the field of plant protection products. This is an imp...
• Analytik Jena sells AJ Blomesystem
  Effective July 1, 2017, Analytik Jena AG sold all of its shares in AJ Blomesystem GmbH to the GUS Group. The sale of the previously wholly owned subsidiary and provider of comprehensive laboratory ...
• New polymer goes for a walk when illuminated
  Scientists at Eindhoven University of Technology and Kent State University have developed a new material that can undulate and therefore propel itself forward under the influence of light. To this ...
• Inorganic biomaterials for soft-tissue adhesion
  Researchers at Okayama University describe a new type of biocompatible adhesive material. The adhesive, made from nanoparticles of hydroxyapatite, glues both synthetic hydrogels and mouse soft tiss...
• The costs of phasing down hydrofluorocarbons
  The Kigali Amendment of the Montreal Protocol aims to phase down the consumption of hydrofluorocarbons (HFCs), chemicals that have strong global warming impacts. IIASA research provides the first a...
