  • Who Are the Jews? Genetic Studies Spark Identity Debate

    Two new studies conclude that most members of the far-flung Jewish Diaspora can trace their roots to ancestors who lived in the Middle East more than 2000 years ago, apparently refuting controversial claims that most of today's Jews descend from more recent converts.

  • Major Heart Disease Genes Prove Elusive

    So far, genome-wide association studies have not found common genes with a big impact on heart health; researchers hope that the low-effect genes they are finding will help identify pathways and drug targets.

  • Researchers to Return Blood Samples to the Yanomamö

    Researchers will be releasing parts of their collections of samples taken from the Yanomamö in Brazil and Venezuela during fieldwork in the 1960s and early 1970s to the Brazilian Embassy in Washington, D.C., which in turn will escort them back to Brazil and the Yanomamö tribe.

    ScienceInsider has been providing dedicated team coverage of the Gulf oil spill, including a critical look at the much-ballyhooed risk that the Loop Current would drive the oil to Florida, among other stories.

  • Synthetic Genome Brings New Life to Bacterium

    In this week's Science Express, researchers describe the stepwise creation of a bacterial chromosome and the successful transfer of it into a bacterium, where it replaced the native DNA. Powered by the synthetic genome, that microbial cell began replicating and making a new set of proteins.
