Chemistry World February 14, 2013 Patrick Walter	Drugs to blame for anti-social fish Swedish scientists say that low levels of psychotherapeutic drugs can change the way fish behave and could be altering the balance of entire aquatic food webs.
Chemistry World February 13, 2013 Michael Parkin	Bone-repairing nanoparticles laced with DNA A bone-repairing nanoparticle paste has been developed that promises faster repair of fractures and breakages. DNA containing two growth-factor genes is encapsulated inside synthetic calcium-phosphate nanoparticles.
Chemistry World February 13, 2013 James Mitchell Crow	Tapping proton power for enantioselective synthesis A simple proton is the key to a novel approach by US-based chemists to synthesize chiral amines and alcohols -- a structural motif common to many organic molecules with pharmaceutical promise.
Chemistry World February 12, 2013 Laura Howes	Biosynthesis of methylmercury discovered It's been acknowledged for years that methylmercury is produced by microorganisms far down the food chain, but what has not been known is how they do it.
Pharmaceutical Executive February 1, 2013 William Looney	In Cancer, Process Drives Progress Today's most important public health story is the advance in our understanding of the biology of cancer.
Chemistry World February 11, 2013 Helen Potter	A new system for cancer detection Cancer cells have been found to differ from normal cells in several ways, including the make up of their cell membranes. Cancer-cell membranes have been found to contain more anionic lipids than normal cells, leading to an overall negatively charged cell surface.
Chemistry World February 11, 2013 Philip Ball	A (chemical) potential theory of life's origin This theory says that life arose at hydrothermal vents, not merely because these provide heat and the ingredients for making complex organics but because they create sustained gradients of ion concentration.
Chemistry World February 6, 2013 Harriet Brewerton	Diagnosing bacterial growth Antibiotics are used regularly for treating bacterial infections, but there is currently no quick and simple test to determine the most effective type or dose of antibiotic for a specific patient infection.
Chemistry World February 5, 2013 Ned Stafford	EU proposes neonicotinoid pesticide ban The European Commission has proposed suspending the use of three neonicotinoid pesticides on any agricultural crops that attract bees, populations of which have steadily declined in recent decades.
Chemistry World February 5, 2013 James Urquhart	Sea urchin inspires carbon capture catalyst UK scientists have taken inspiration from the sea urchin and shown how nickel nanoparticles could be a cheap and re-usable catalyst in a key step for capturing carbon dioxide produced by power plants and the chemical industry.
