Chemistry World April 23, 2013 Laura Howes	Carving graphene snowflakes with gases Beautiful flakes aren't made of ice but are instead etched into a sheet of graphene. A group at the Beijing National Laboratory for Molecular Sciences in China, etched the graphene flakes using a flow of argon and hydrogen gas.
Chemistry World April 23, 2013 David Bradley	A sweet switch for an ageing heart Studies revealing how the protein elastin -- found in heart tissue and blood vessels -- responds electrically to glucose could offer new clues to problems that arise as we get older, including loss of elasticity in major blood vessels and arteriosclerosis.
Chemistry World April 23, 2013 Derry Jones	A history of the electron: JJ and GP Thomson In the absence of full biographies of father and son, this book by Jaume Navarro, provides a short joint history of the electron and the Thomsons (especially JJ), and their interactions, with an emphasis on emerging science in the 1920s and early 1930s.
Chemistry World April 22, 2013 Andrea McGhee	Creating biodegradable electronics using shellac Scientists in Austria, Romania and Turkey have used the natural resin shellac to devise biocompatible organic field-effect transistors, which could help make electronic gadgets biodegradable and allow easier use of OFETs in the body.
Chemistry World April 22, 2013 Rebecca Brodie	Quicker checks for safer water Scientists in the Netherlands have developed and tested a new method that uses Raman spectroscopy to quickly identify harmful bacteria in drinking water.
Chemistry World April 19, 2013 James Urquhart	Solar boost for gas power stations US researchers are developing a system that could boost the efficiency of gas-fired power plants while reducing their greenhouse emissions.
Chemistry World April 18, 2013 Yuandi Li	Reducing the cost of perovskite solar cells A new way of making semiconducting perovskite-based solar cells could result in photovoltaic devices that are 70% cheaper than current commercial models, say UK scientists.
Chemistry World April 16, 2013 Emma Stoye	Polymer 'nano-suit' protects insects from vacuum Japanese scientists have shown that coating insect larvae with Tween-20, a common detergent, lets them survive the powerful vacuum inside an electron microscope. The technique could pave the way for high resolution live imaging.
Chemistry World April 11, 2013 Philip Robinson	Terahertz turns up fresco's hidden artwork Analytical scientists revealed a hidden work under one of the Louvre Museum's frescoes. The research is an example of the broadening field of terahertz spectroscopy, using wavelengths of electromagnetic radiation between microwave and infrared.
Chemistry World April 4, 2013 Emma Shiells	Power-up with edible electronics Since 2008, Christopher Bettinger and colleagues from Carnegie Mellon University in Pittsburgh, Pennsylvania, have been working on biodegradable electronics for medical devices.
