Shedding light on oxygenated life

  • New study sheds light on evolutionary origin of oxygen-based cellular respiration - Researchers at the RIKEN SPring-8 Center in Harima, Japan have clarified the crystal structure of quinol dependent nitric oxide reductase (qNOR), a bacterial enzyme that offers clues on the origins of our earliest oxygen-breathing ancestors. In addition to their importance to fundamental science, the findings provide key insights into the production of nitrogen oxide, an ozone-depleting and greenhouse gas hundreds of times more potent than carbon dioxide.
  • Video simulation puts a new twist on fusion plasma research

  • Video simulation puts a new twist on fusion plasma research - Samuel Lazerson, an associate research physicist in advanced projects at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL), has created a video simulation showing the intricate nature of a plasma pulse within an experimental fusion machine known as a heliotron. The simulation shows the superconducting field coils, saddle loops, and plasma of the Large Helical Device (LHD) at the National Institute for Fusion Science in Japan.
  • Nanopore structures could tune drug crystallisation

  • Nanopore structures could tune drug crystallisation - Researchers from the US and Japan have shown that the crystallisation of a solute can be profoundly influenced by the shape of nanopores on the surface it is placed upon. The finding potentially offers a new way to tune the rate of crystallisation of different compounds and the morphology of the crystals that are formed - which are important considerations in the manufacture of certain drugs and fine chemicals.
  • DNA readers: Cracking the epigenetic code

  • DNA readers: Cracking the epigenetic code - Decoding some of the subtler information encoded in our DNA could soon become a high-throughput process, a team of researchers in Japan have shown. Masateru Taniguchi and colleagues at Osaka University have shown that DNA-borne chemical markers, which play a key role in gene expression, can be detected electrically using nanoscale electrodes ("Electrical Detection of Single Methylcytosines in a DNA Oligomer").
  • Liquid crystals rearrange to glow in three different colours

  • Liquid crystals rearrange to glow in three different colours - Chemists in Japan have created a luminescent liquid crystal that can switch between three different colours when stimulated with heat and mechanical force. A handful of organometallic and organic compounds can switch between two colours, but none between three. The system could open the way to new sensor or display technologies, the researchers suggest.
