• Tracking down nano-size current loops using polarized neutrons
  Determining the origin of high-temperature superconductivity is probably the single most important challenge faced today by solid-state physicists. This despite 30 years of extensive research effo...
• Research uncovers a unique microbial cloud that surrounds people
  Research done at the UO shows that we all have our own microbial cloud made up of bacteria exuded by the skin and breath, and each cloud is unique to that person. Think of it as an organic signatur...
• Discovery of the redox-switch of a key enzyme involved in n-butanol biosynthesis
  Two Korean research teams at the Kyungpook National University (KNU) and the Korea Advanced Institute of Science and Technology (KAIST) have succeeded in uncovering the redox-switch of thiolase, a ...
• Laser-based molecular fingerprinting
  Scientists often need to detect and measure levels of specific substances in a sea of irrelevant molecules, and infrared light offers an ideal tool for this task. Infrared radiation is invisible to...
• Nanoparticles can make medicines more effective
  Nanoparticles disguised as human platelets could greatly enhance the healing power of drug treatments for cardiovascular disease and systemic bacterial infections. These platelet-mimicking nanopart...
• What happens on the molecular level when smog gets into the lungs?
  Coughing. A sore throat. Maybe a pain in your chest as you take a deep breath? These are all common symptoms for many city-living Australians when smog levels are high. And while it is well underst...
• New insights into the structure of the Golgi apparatus by cryo-electron tomography
  The Golgi apparatus serves as a cellular post office, sending the cell's many proteins to their correct destinations. In order to mark and sort the proteins, the Golgi has an elaborate architecture...
• Hydrogen from sunlight: new efficiency record for artificial photosynthesis
  An international team has now succeeded in considerably increasing the efficiency for direct solar water splitting. They are using a tandem solar cell whose surfaces have been selectively modified....
• Nano in food and agriculture: regulations require collaboration to ensure safety
  An overview of regulatory solutions worldwide on the use of nanotechnology in food and feed production shows a differing approach: only the EU and Switzerland have nano-specific provisions incorpor...
• Cost-effective recycling of rare earths from permanent magnets
  Electric motors or wind turbines are driven by powerful permanent magnets. The most powerful ones are based on the rare earth elements neodymium and dysprosium. In future, a new process route reali...
• Graphene as an alternative transparent electrode for OLEDs
  The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP will show for the first time organic light emitting diodes (OLEDs) on graphene at Plastic Electronics 2015 ...
• Single Molecule Detection Machine for Nucleic Acid Analytics
  At BIOTECHNICA, October 6 - 8, 2015, Fraunhofer FIT will present a Single Molecule Detection Machine for the analysis of ultra-small amounts of nucleic acid. The system can be used to identify biom...
• New microscopy methods revolutionize neuroscience
  Anyone who wants to understand the brain must be able to see the brain's microscopically small switching units - the neurons - at work. Conventional light microscopes are not sufficient to do the j...
• Phagraphene, a "Relative" of Graphene, discovered
  A group of scientists from Russia, the USA and China, led by Artyom Oganov from the Moscow Institute of Physics and Technology (MIPT), using computer generated simulation have predicted the existen...
• Aqueous light driven hydrogen production
  Refined by nature over a billion years, photosynthesis has given life to the planet, providing an environment suitable for the smallest, most primitive organism all the way to our own species. Whil...
• Metallic gels produce tunable light emission
  Researchers at MIT have developed a family of materials that can emit light of precisely controlled colors - even pure white light - and whose output can be tuned to respond to a wide variety of ex...
• ESCMID publishes guidelines aimed at preventing build-up of dangerous biofilms
  The European Society of Clinical Microbiology and Infectious Disease (ESCMID) - an organization that explores the risks and best practices in infectious disease - advocates the need for greater edu...
• High-resolution STED microscopy provides new insights into cellular power plants
  Scientists from the Max Planck Institute for Biology of Ageing (MPI AGE) in Cologne, the Max Planck Institute of Biophysics (MPI BP) in Frankfurt a.M., and the Max Planck Institute for Biophysical ...
• Wastewater to irrigate, fertilize and generate energy
  To meet the requirements of Asian cities, researchers are adapting an idea they have already applied in Germany for comprehensive water management: They are developing a concept for reducing water ...
• Millions of plastic particles found in cosmetic products
  Everyday cosmetic and cleaning products contain huge quantities of plastic particles, which are released to the environment and could be harmful to marine life, according to a new study. Research a...
• Single Cell Mass Spectrometry allows getting a picture of molecules
  Understanding exactly what is taking place inside a single cell is no easy task. For DNA, amplification techniques are available to make the task possible, but for other substances such as proteins...
