Chemistry World October 12, 2015 Andy Extance	'Chemical search engine' backs alternative route to life A key class of biological molecules neglected in the search for life's chemical origins could have appeared spontaneously before organisms, UK scientists say.
Chemistry World July 24, 2015 Michael Spencelayh	Mineral analysis surveys shark smile evolution New research by scientists in Germany has uncovered a curious difference between present-day shark teeth and those of their prehistoric relatives.
Chemistry World July 3, 2015 Ida Emilie Steinmark	Iron found in ancient rock is recycled from bacteria Isotopic analysis suggests that some of the iron within rock formations was processed by bacteria 2.5 billion years ago
Chemistry World January 28, 2015 Emma Stoye	Tiny volcanic cracks 'incubated' ancient DNA Tiny pores within volcanic rocks on ancient Earth may have provided the ideal conditions for replicating molecules, and could also have driven the evolution of longer and longer genetic sequences, researchers in Germany have shown.
Chemistry World January 7, 2015	Flowing rivers of mercury Philip Ball investigates claims that the burial chamber of China's first emperor contains rivers of shimmering mercury.
Chemistry World December 8, 2014 James Urquhart	Asteroid bombardment of early Earth may have created building blocks of life Scientists in the Czech Republic and US have shown how asteroid collisions with early Earth could have sparked reactions that produced the basic chemical building blocks of life four billion years ago.
Chemistry World November 14, 2014 Matthew Gunther	Polymer preservative set to save wooden artefacts A novel polymer network that soaks into wood and provides artifacts with structural support while simultaneously protecting against biological degradation has been developed.
Chemistry World September 3, 2014 Emma Stoye	Iron Age chemists ate like kings Archaeologists in Israel have found new evidence that Iron Age 'chemists' -- metal smelters who could extract copper from its ore -- dined on fine meat and fish, and were admired and respected for their ability to get valuable metal from lumps of rock.
Chemistry World July 2, 2014 Tim Wogan	Miller's forgotten experiments point to primitive protein genesis Stanley Miller's experiments are still adding to our understanding of prebiotic Earth.
Chemistry World March 11, 2014 Tim Wogan	Dinosaur mass extinction may have been triggered by acid rain Most scientists accept the principal cause of the Cretaceous -- Tertiary mass extinction was a 10km asteroid hitting the Yucatan peninsula, but the precise mechanism by which this caused the extinction remains controversial.
