The liver’s carbon fixation The possibility that insects can harness solar energy (SN: 1/15/11, p. 8) is no less fascinating than the ability of the mammalian liver to do the light-independent part of photosynthesis: carbon fixation. When concentrations of the amino acid methionine rise after a high-protein meal, the liver shifts gears to get rid […]

2010 Science News of the Year: Genes & Cells
Credit: © Joe McNally/reconstruction by Kennis and Kennis Gene sequencing for all, even Neandertals An unprecedented picture of life’s diversity is emerging as researchers publish the full genetic instruction books of a growing list of species — including one that has been extinct for more than 30,000 years. A project sequencing Neandertal DNA harvested from […]
