Chemistry World February 16, 2012 Simon Hadlington	'Proton grease' speeds up molecular rotor A molecular rotor whose spin can be accelerated 10-million-fold when its mechanism is 'lubricated' by protons has been synthesized by chemists in the US.
Chemistry World February 15, 2012 James Urquhart	Branched organic nanowire heterojunctions Chinese researchers have combined two organic materials to create branched organic nanowire heterojunctions for the first time.
Chemistry World February 12, 2012 Laura Howes	Thermal imaging on the wing By adding carbon nanotubes to butterfly wings chemists have been able to turn these nanostructures into an infrared detector.
Chemistry World February 10, 2012 Elinor Richards	Instant ecstasy detector The probe has been designed to detect the active ingredient in ecstasy - MDMA (3,4-methylenedioxymethamphetamine) - even when it is mixed with other common additives, which has been a challenge.
Chemistry World February 9, 2012 Kate McAlpine	Tiny pump senses chemical changes and acts A team of researchers at Pennsylvania State University has developed a microscale pump that turns on in the presence of a particular chemical, with a flow rate that depends on that chemical's concentration.
Chemistry World February 8, 2012 Jon Evans	DNA walker strides towards the light DNA molecules are now able to enjoy a stroll in the sunshine, thanks to US and Chinese chemists who have developed the first light-powered DNA walker.
Chemistry World February 7, 2012 Simon Hadlington	Nano-welding with a light touch US researchers have found a new way to weld together metal nanowires - simply by bathing them in white light.
HHMI Bulletin February 2012 Sarah C. P. Williams	Force Factor In the context of cells, forces are required to move molecules. Quantifying these forces gives scientists a way to compare and contrast different molecular motors.
Chemistry World February 2, 2012 Philip Robinson	Ultrafast NMR shows the way Chemists have created an ultrafast NMR technique that can 'watch' how chemical reactions occur in real time. They've used the technique to follow the formation of pyrimidines from carbonyls and even identified new intermediates never before thought to be part of the reaction.
Chemistry World February 2, 2012 Elinor Richards	Magical microwaves Microwaves have been used to promote organic reactions since the 1980s and they can lead to higher yields and shorter reaction times than conventional heating, but why?
