Current Biology & Life Sciences Articles

Chemistry World May 10, 2013 Michael Parkin	Super Glue for cells Scientists in Canada have made a super-strong cell membrane adhesive and used it to stick red blood cells together. The polymer, based on the phospholipid head group phosphatidyl choline, could be used to secure cells in particular positions for tissue engineering and wound closure.

Chemistry World April 29, 2013 Michael Parkin	Food safety test for harmful dye It may soon be easier to protect consumers from dangerous condiments thanks to an electrochemical method developed by Chinese scientists that can spot the toxic azo dye, Orange II.
Chemistry World April 25, 2013 James Urquhart	Filler to patch up ancient silk delicates Chinese researchers have found a way to restore and strengthen ancient, fragile silk fabrics using an enzyme-mediated reaction to fill in tiny cracks in the fibers.
Chemistry World April 24, 2013 James Urquhart	Color changing nanoparticles inspired by deep sea denizens Inspired by the camouflage abilities of marine organisms, such as the cuttlefish, US researchers have created striped ellipsoid particles using controlled self-assembly of diblock copolymers.
Chemistry World April 24, 2013 Helen Bache	3D microfluidic liver on a chip Researchers have developed a three-dimensional liver model that can recreate cell signalling within the organ. The liver on a chip could cut tests on animals by providing an accurate artificial model of how the organ responds to new drugs.
Chemistry World April 23, 2013 David Bradley	A sweet switch for an ageing heart Studies revealing how the protein elastin -- found in heart tissue and blood vessels -- responds electrically to glucose could offer new clues to problems that arise as we get older, including loss of elasticity in major blood vessels and arteriosclerosis.
Chemistry World April 22, 2013 Andrea McGhee	Creating biodegradable electronics using shellac Scientists in Austria, Romania and Turkey have used the natural resin shellac to devise biocompatible organic field-effect transistors, which could help make electronic gadgets biodegradable and allow easier use of OFETs in the body.
Chemistry World April 22, 2013 Rebecca Brodie	Quicker checks for safer water Scientists in the Netherlands have developed and tested a new method that uses Raman spectroscopy to quickly identify harmful bacteria in drinking water.
Chemistry World April 17, 2013 Andy Extance	Electron flashes catch organics in the act Researchers based in Canada, Germany and Japan have overcome the difficulties of collecting diffraction data on small organic molecules to make atomic-scale recordings of their movement.
Chemistry World April 16, 2013 Emma Stoye	Polymer 'nano-suit' protects insects from vacuum Japanese scientists have shown that coating insect larvae with Tween-20, a common detergent, lets them survive the powerful vacuum inside an electron microscope. The technique could pave the way for high resolution live imaging.
Chemistry World April 16, 2013 Amy Middleton-Gear	Sieving silica sieves from biomass ash A team, led by Duncan Maquarrie at the University of York, developed an efficient route for extracting the silicates by forming alkali silicate solutions.

Chemistry World April 15, 2013 Phillip Broadwith	Polymer lubricant may stave off knee surgery A synthetic polymer could make a better replacement lubricant for joint cartilage in people with arthritis, US researchers claim. The polymer is not broken down in the body like currently used replacement lubricants.
Chemistry World April 11, 2013 Mark Peplow	Pesticide bee buzz needs more evidence There are opportunistic infestations that gain a foothold in hives where bees are already weakened by some other factor. Could that factor be pesticides? A growing body of scientific evidence suggests that neonicotinoid pesticides could indeed be responsible for colony collapse disorder.
