Chemistry World February 28, 2013 Andy Extance	Chemical transport defines 'Goldilocks' cell size A US team has suggested molecular movement as an answer to the question of why cells are the size they are. A question that they say 'still awaits an answer from first principles'.
Chemistry World February 26, 2013 Richard Henchman	Entropy and the second law: interpretation and misss-interpretationsss In the debate about the best way to teach and understand entropy in thermodynamics, Arieh Ben-Naim forcefully advocates the probabilistic interpretation of thermodynamic entropy in terms of (Claude) Shannon's measure of information.
Chemistry World February 22, 2013 Sarah Farley	Electronic tongue develops a taste for brandy A team of Spanish scientists is set to replace the human palette with an electronic tongue that classifies brandy according to taste, and can even discriminate between aging methods.
Chemistry World February 22, 2013 Anthony King	LED triggers microfluidic mixing French scientists have developed a way to mix fluids in microfluidic devices using light from an external LED as a trigger. The strategy is simple but offers good control over mixing without complex components.
Chemistry World February 20, 2013 Amy Middleton-Gear	Ohmic heating for efficient green synthesis Portuguese scientists have developed a new ohmic-heating reactor for organic syntheses on water, or chemistry using an aqueous suspension of the reactants.
Chemistry World February 20, 2013 Jessica Cocker	Raman spectroscopy for bedside cancer diagnosis Currently the only way to identify whether a suspicious lump is something to be concerned about is to have it removed and then examined. But a new diagnostic technique based around Raman spectroscopy could provide a faster diagnosis.
Chemistry World February 19, 2013 Andy Extance	Insulator pile shows solar potential Stacks of insulating transition metal oxides could effectively convert sunlight into electricity. A team in Austria, has calculated that layering LaVO 3 on a SrTiO 3 base could also deliver advantages conventional semiconductors can't.
Chemistry World February 13, 2013 Alexander Hellemans	ESRF upgrade gears up for industry The European Synchrotron Radiation Facility in Grenoble, France, has called on its user community to discuss the scientific prospects of a second phase of an upgrade, to be completed by 2020.
Chemistry World February 11, 2013 Simon Hadlington	Footfalls to power static nanogenerator Recharging your laptop battery with energy derived simply from walking has moved a step closer with new research where scientists have developed a novel generator that can produce significant amounts of electrical power from static electricity.
Chemistry World February 6, 2013 Jennifer Newton	Electricity at your fingertips Scientists in South Korea have made a conducting polymer as part of a thin-film thermoelectric device that can generate electricity from the temperature difference between your fingertips and the environment.
