Chemistry World August 19, 2009 Hayley Birch	Gold nanoparticles detect cancer Chinese scientists have used gold nanoparticles as ultrasensitive fluorescent probes to detect cancer biomarkers in human blood.
Chemistry World August 18, 2009 Jon Cartwright	Ozone reaction with skin causes irritants Armin Wisthaler of the Leopold-Franzens University of Innsbruck, Austria, and Charles Weschler of Rutgers University in New Jersey, US, have performed a study of ozone with human occupants in an office environment.
Scientific American September 2009 Melinda Wenner	Gene therapy: An Interview with an Unfortunate Pioneer Lessons learned by James M. Wilson, the scientist behind the first gene therapy death
Scientific American September 2009 Michael Tennesen	More Animals Seem to Have Some Ability to Count Counting may be innate in many species
Scientific American September 2009 Michael Moyer	Quantum Entanglement, Photosynthesis and Better Solar Cells Quantum details of plants' food-making ability could improve photovoltaic technology
Chemistry World August 17, 2009 Lewis Brindley	DNA shapes up for nanoelectronic devices Researchers have taken a step towards the next generation of high-speed computer chips by controlling how triangle-shaped pieces of DNA mount themselves on a surface.
Chemistry World August 13, 2009 Simon Hadlington	Forcing enzyme activity New research has shown that physically stretching an enzyme can trigger its activity - even when the active site is not hidden in a 'cryptic' position. Mechanical force may play a more important role in biological molecular systems than previously realized.
Chemistry World August 11, 2009 Jon Cartwrigh	Yushchenko poisoning study calls for dioxin tests Research into the non-fatal poisoning of Ukrainian president Viktor Yushchenko in 2004 has revealed the unexpected breakdown of the dioxin used to poison him, and prompted researchers to call for the development of new methods to spot the compound's metabolites.
Chemistry World August 10, 2009 James Urquhart	Stretching for reversible enzyme activation A new kind of biologically inspired nanomaterial that can be chemically turned on and off by mechanical stretching has been devised by French researchers.
Chemistry World August 6, 2009 Hayley Birch	Nanoscale tools from DNA origami US scientists have demonstrated a nanoconstruction approach that allows the creation of self-assembling DNA 'origami' folded in an array of different shapes, from bent rods to toothed gears. This opens new possibilities for engineering nanoscale tools and devices.
