Chemistry World January 9, 2013 Andy Extance	Crystals aim to light up dark matter German scientists hunting dark matter are set to produce half a ton of high-purity calcium tungstate for their detectors, one 1kg crystal at a time.
Chemistry World January 7, 2013 James Urquhart	Kilogram ready to slim down for the new year UK scientists have developed a cleaning technique that could solve a long-standing puzzle in the field of metrology -- how to return the standard kilogram, against which all others are measured, to its original mass.
Chemistry World January 4, 2013 Phillip Broadwith	Laser guided maglev graphite air hockey A graphite disk levitating over a bed of rare earth permanent magnets can be 'pushed' around or made to spin using a laser beam, Japanese scientists have shown. The phenomenon can also be used to convert sunlight into movement, offering a possible alternative way to harness solar energy.
Chemistry World January 2, 2013 Philip Robinson	Shine on you crazy Diamond The UK's Diamond Light Source is celebrating five years since it opened its doors to scientists. The joint venture between the Science and Technology Facilities Council and the Wellcome Trust established Diamond as the successor to the UK's previous synchrotron source at Daresbury.
Chemistry World December 19, 2012 Andrea Sella	Wedgwood's pyrometer Josiah Wedgwood. English potter and chemist (1730 -- 1795), invented a system for measuring the extreme heat of kilns and furnaces.
Chemistry World December 11, 2012 Elinor Hughes	Worried about food allergens? There's an app for that Building on their work on a mobile phone -- or cell phone -- app to detect bacteria, US scientists have now adapted the technology to detect allergens in foods.
Chemistry World November 28, 2012 Philip Ball	Make or break: the laws of motion The machine metaphors of nanochemistry and molecular biology now make it plain that dynamic function arises from the use of weak, temporary interactions. The question biology has to face is: what is the optimal bond strength for a given mechanical function?
Chemistry World November 21, 2012 James Urquhart	Two-faced particles self-assemble in sync US scientists have synchronized the motion of colloidal magnetic spheres with a rotating magnetic field and found that the particles self-organize into micrometer-sized tubes.
Chemistry World November 13, 2012 Rachel Cooper	Detecting cancer cells and parasites Scientists in Denmark have designed a new sensor to detect cells that over-express folate receptors, including cancer cells. The sensor consists of an electrochemical platform composed of graphene and peptide nanotubes with folic acid.
Chemistry World November 13, 2012 Phillip Broadwith	Calculations correct natural product structure US chemists have used NMR prediction calculations to correct the structure of a complex natural product, aquatolide. The work emphasises the power of this burgeoning technique to challenge and inform experimental structure determination.
