  • Extreme oxygen isotope anomaly with a solar origin detected in meteoritic organics – Analysis of micrometre-sized grains of acid-insoluble organic matter from a carbonaceous chondritic meteorite recovered in Antarctica shows that the organic matter has the highest 18 O/16 O and 17 O/16 O ratios known in planetary material, except for pre-solar grains
  • Predicting Myelosuppression of Drugs from in Silico Models – A study has been carried out to develop computational models able to predict the potential myelotoxicity of drugs from their chemical structure.
  • High-efficiency dye-sensitized solar cells with ferrocene-based electrolytes – Energy conversion efficiencies of 7.5% (simulated sunlight, AM1.5, 1,000 W m−2) are reported for dye-sensitized solar cells combining the archetypal ferrocene/ferrocenium (Fc/Fc+) single-electron redox couple with a novel metal-free organic donor–acceptor sensitizer (Carbz-PAHTDTT). These Fc/Fc+-based devices exceed the efficiency achieved for devices prepared using I−/I3− electrolytes under comparable conditions, revealing the great potential of ferrocene-based electrolytes in future dye-sensitized solar cells applications.
  • Scripps Research scientists reveal key mechanism governing nicotine addiction – Scientists from the Florida campus of The Scripps Research Institute have identified a pathway in the brain that regulates an individual's vulnerability to the addictive properties of nicotine. The findings suggest a new target for anti-smoking therapies.
  • New transistors: An alternative to silicon and better than graphene – Smaller and more energy-efficient electronic chips could be made using molybdenite. In an article appearing online January 30 in the journal Nature Nanotechnology, EPFL's Laboratory of Nanoscale Electronics and Structures (LANES) publishes a study showing that this material has distinct advantages over traditional silicon or graphene for use in electronics applications.
