Chemistry World November 13, 2007 Lewis Brindley	Hydrogen From Sewage Hits Production Records Scientists have drastically improved the efficiency of bacteria-powered fuel cells that convert biodegradable organic matter into hydrogen gas. They hope their discovery will make it possible to generate hydrogen from sewage, sustainably and on a large scale.
Chemistry World November 12, 2007 Victoria Gill	Chemistry Reveals Oldest Known Chocolate Drink Chemical analysis of pottery fragments from bottles found in Honduras has uncovered an ancient, alcoholic chocolate drink. The finding has pushed back the earliest use of cacao more than 500 years, to between 1100 and 1400 BC.
Chemistry World November 12, 2007 Simon Hadlington	Coupled Enzymes May Spawn New Catalysts Chemists at the University of Oxford have created a new type of catalyst by attaching two enzymes to a microscopic flake of graphite. The system could be tailored to catalyze a range of reactions, the researchers say.
Chemistry World November 8, 2007 James Mitchell Crow	First Mg(I) Complex Made Chemists have created the first stable magnesium(I) compounds, a breakthrough for a metal whose chemistry is ruled by the oxidation state.
Chemistry World November 8, 2007 Lewis Brindley	Radiation Damage Puzzle Cracked Two studies have provided new insight into how radiation causes nano-scale defects in materials, changing their properties dramatically or leading to dangerous cracks that weaken them.
Chemistry World November 7, 2007 James Mitchell Crow	Shortest Metal Bond Chemists in the US have made a quintuply-bonded dichromium complex with the shortest metal-metal bond ever isolated.
Chemistry World November 6, 2007 Lewis Brindley	Soybeans Strike Nanogold A simple mix of soybeans, water and gold salts may hold the secret to producing gold nanoparticles without harming the environment, according to one team of US researchers.
Chemistry World November 5, 2007 Ned Stafford	Joining up Nanocircuits A team of scientists have covalently bonded strings of porphyrin molecules on a gold surface -- a step forward in the quest to develop nano-electronics.
Food Engineering November 4, 2007 Kevin T. Higgins	Ice Cold Nanotech Heat degrades food nutrition and flavor, and size reduction can impart tremendous heat. Cryogenic fine grinding is being tested to deliver superior foods and new packaging materials.
Chemistry World November 1, 2007 Richard Van Noorden	Step Change for Organic Synthesis US chemists discovered how to attack a complex molecule's unreactive carbon-hydrogen bonds, without resorting to wasteful synthetic aids like protecting and directing groups.
