Chemistry World March 4, 2014 Rebecca Brodie	Geological technique adapted to analyse Aboriginal Australian objects Australian scientists have used a device initially designed for the mining industry to analyze the mineral content of pigments on wooden objects of cultural significance.
Chemistry World December 2, 2013 Ian Randall	Mass extinction the result of acid rain and ozone loss Widespread rain as acidic as lemon juice and the destruction of as much as 65% of the ozone layer may have played a major role in the largest mass extinction in the fossil record.
Chemistry World November 22, 2013 James Urquhart	Earliest use of chilli sauce put back hundreds of years Chemical analysis of 2000 year old pottery artifacts unearthed in southern Mexico suggests that the people living there were spicing up their diet with chilli sauce and drinking chilli flavored beverages, almost a thousand years earlier than previously thought.
Chemistry World November 18, 2013 Emily James	Meat mummies a feast fit for a Pharaoh An important contribution to our knowledge of ancient mummification methods comes from advanced chemical analysis of the ingredients incorporated into organic balms.'
Chemistry World October 8, 2013 Lorna Anguilano	Analytical archaeometry This book is a very good compendium of analytical techniques, mainly non-destructive, including highly detailed description of tools and principles, maybe with a slight overemphasis on Raman spectroscopy.
Chemistry World September 25, 2013	Coloring in the dinosaur book Chemists' best known contributions to palaeontology are probably radiocarbon dating and stable isotope analysis. But they now face a bigger challenge that has traditionally fallen into the hands of artists: adding color to the ancient world.
Chemistry World August 29, 2013 Anthony King	Prehistoric humans liked to spice up their lives Our taste for spice goes way back into prehistory, research has shown.
Chemistry World June 14, 2013 Michael Parkin	Plumage pattern revealed in 150 million-year-old bird An international team of scientists has used synchrotron-based imaging techniques to chemically map the feather colors of a 150 million-year-old bird. The study reveals that the dinosaur had feathers which were light in colour with a dark edge and tip, rather than all black as previously thought.
Chemistry World May 22, 2013 James Urquhart	Digitally unrolling historical scrolls Historical parchment scrolls that have become too fragile to be unrolled could soon catch up with the digital age and be read again thanks to an X-ray imaging technique developed by UK researchers.
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.
