2010 Science News of the Year: Body & Brain
Credit: © Bettmann/Corbis Gene therapy moves forward Despite their promise, technologies to correct defective genes have been plagued by safety problems leading to unintended — and sometimes fatal — outcomes. But scientists are inching toward safer, more effective gene therapies that may one day treat a range of diseases, from psychiatric disorders to autoimmune diseases […]

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 […]
