Chemistry World April 14, 2011 Laura Howes	DNA origami yields tiny flask A US group of researchers has made a round bottomed flask from folded up DNA with an internal capacity of just 24000nm 3, which would be enough to hold 800,000 molecules of water.
Chemistry World April 14, 2011 Sarah Farley	Fish in chips: growing embryos in microfluidic systems Scientists in the Netherlands and the UK have shown for the first time that an animal embryo can develop in a microfluidic environment.
Chemistry World April 13, 2011 Kate McAlpine	Microrockets aim at cancer diagnostics Researchers at the University of California, San Diego, have made self-propelled microtube rockets that can find and capture cancer cells from blood samples.
Chemistry World April 12, 2011 Meera Senthilingam	How antidepressants spur brain growth Researchers have identified the mechanism by which some antidepressants stimulate the formation of new brain cells, an insight that could lead to improved drugs.
Chemistry World April 7, 2011 Laura Howes	Long chains give new life to RNA world hypothesis The so-called RNA world hypothesis has gained fresh momentum with the synthesis of the longest lab grown RNA strands made using an enzyme that is itself made of RNA, an 'RNAzyme'.
National Defense May 2011 Eric Beidel	Will African Rodents Join Hunt for IEDs? The Army Research Office recently awarded a $740,000 grant to Oklahoma State University zoology professor Alex Ophir to find out which rat personalities are the best for detecting bombs.
Chemistry World April 4, 2011 Carol Stanier	Mighty micelles that make themselves Scientists in the US and Singapore have made self assembling micelles of cationic polymers that kill bacteria but are biodegradable - raising further hope of a nanotechnology solution to the problem of antibiotic resistance.
Chemistry World April 4, 2011 Jon Cartwright	New cream blocks nickel allergy The treatment uses nanoparticles to trap nickel on the skin of mice before it is absorbed- but there is some doubt whether it will work equally well with humans.
Chemistry World April 1, 2011 Hayley Birch	Nanoparticles help reveal hidden fingerprints A technique using gold nanoparticles in combination with antibodies has shown promising results for enhancing fingerprints that are over a week old.
