Top scientists and ethicists from seven countries on Wednesday called for a global moratorium on gene editing of human eggs, sperm or embryos that would result in genetically-altered babies after a rogue Chinese researcher last year announced the birth of the world's first gene-edited twins. News of their birth prompted global condemnation of the work, raising the ethical specter of so-called designer babies in which embryos could be genetically modified to produce children with desirable traits. Toyota, Japan space agency join forces to develop moon rover

Toyota Motor Corp, one of the world's largest automakers, and Japan's space agency said on Tuesday they had agreed to cooperate in developing a manned lunar rover that runs on fuel cell technologies. Although Japan has no plan currently to make a manned rocket that could send people into space, the rover could be a major contribution to an international space probe program in the future, the Japan Aerospace Exploration Agency (JAXA) said. Space station crew confident on eve of first launch since rocket failure
