Science News March 24, 2007 Janet Raloff	Planting the Seeds for Folate Enrichment Florida scientists have engineered tomatoes with 20 times the ordinary amount of folate, making them the most concentrated source of this important vitamin ever measured.
Chemistry World March 23, 2007 John Bonner	Mice Get Full-Colour Vision Genetically engineered mice that see the world in full color, or at least in the same colors as humans see, have been created in a US lab. Most mammals lost the ability to distinguish colors during the age of the dinosaurs.
Chemistry World March 22, 2007 Michael Gross	Eat Isotopes to Live Longer Food containing heavy isotopes of hydrogen, carbon and nitrogen could slow down the aging process. That's the claim of a biochemist who suggests that seeding key biological molecules with deuterium or carbon-13 could drastically reduce oxidative damage or even avert it altogether.
Chemistry World March 21, 2007 Alison Stoddart	Synthesis Strategy Offers no Protection A radically different approach to constructing complex molecules could help to tap the pharmaceutical potential of natural products.
Chemistry World March 21, 2007 Henry Nicholls	The Molecular Cannibal in Vitamin B12 Synthesis An enzyme called BluB single-handedly carries out an act of 'molecular cannibalism', pulling apart vitamin B 2 (riboflavin) to produce a key component of vitamin B 12 known as 5,6-dimethylbenzimidazole (DMB). This fills a glaring gap in our understanding of the biosynthesis of the vitamin.
Chemistry World March 20, 2007 Lionel Milgrom	Chemical Model Unlocks Key Enzyme's Secrets The precise workings of cytochrome c oxidase (CcO), an enzyme that is crucial for all aerobic life, have been unveiled.
Chemistry World March 19, 2007 Jessica Ebert	Pocket-Sized PCR Machine Scientists in the US report being one step closer to designing a miniaturized, portable polymerase chain reaction machine that could be used for applications such as point-of-care diagnostics.
Chemistry World March 19, 2007 Lionel Milgrom	Gallium-Based Antimicrobials Antibiotic-resistant bacteria can be killed with gallium. US researchers used gallium as a 'Trojan horse' to fool bacteria into thinking they were feeding on iron. Bacteria need iron to survive, but they cannot distinguish between iron and gallium.
Chemistry World March 15, 2007 Henry Nicholls	The Mother of All Enzymes Scientists have uncovered the three-dimensional structure of what might be biology's first enzyme. This sheds light on the chemistry at a key moment in the origin of life, they argue.
Bio-IT World March 2007 Kevin Davies	Biogen-Idec's Innovation Incubator In this imaginative new business model, Biogen-Idec will provide facilities, funding, and expertise to help scientific entrepreneurs develop new therapeutic candidates.
