Here’s whyThis week, scientists are gathering in Washington, D.C., for an annual meeting devoted to gene therapy—a long-struggling field that has clawed its way back to respectability with a string of promising results in small clinical trials. Now, many believe the powerful new gene-editing technology known as CRISPR will add to gene therapy’s newfound momentum. But is CRISPR really ready for prime time? Science explores the promise—and peril—of the new technology.World’s largest chimpanzee research facility to release its chimps In what it is calling the largest resettlement of chimpanzees from a U.S. research center, Louisiana’s New Iberia Research Center announced this week that it will move all 220 of its chimps to a sanctuary in Blue Ridge, Georgia. The animals include Hercules and Leo, which have been the subject of an intense legal battle over the legal rights of chimps.Why this lab-grown human embryo has reignited an old ethical debateResearchers studying human embryos in the lab have always hit a roadblock at about 7 days—the point where the embryo would usually attach to the uterus. Now, two teams report growing human embryos about a week past that point, revealing key differences between the development of human and mice embryos. The limit now isn’t technological, but ethical. A widely held rule dictates all embryo research should be stopped at 14 days—but some scientists and bioethicists are saying the rule should be revisited.Scientists hit pay dirt in drilling of dinosaur-killing impact craterScientists have reached ground zero for one of the world’s most famous cataclysms. Burrowing into the impact structure responsible for the demise of the dinosaurs, a team of researchers has achieved one of its main goals, with rocks brought up from 670 meters beneath the sea floor off the coast of the Yucatán Peninsula in Mexico. These samples contain bits of the original granite bedrock that was the unlucky target of cosmic wrath 66 million years ago, when a large asteroid struck Earth, blasted open the 180-kilometer-wide Chicxulub crater, and led to the extinction of most life on the planet.Zika vaccine efficacy trials could start in 2017The U.S. National Institute of Allergy and Infectious Diseases (NIAID) in Bethesda, Maryland, plans to begin tests of a vaccine made in its labs in 80 people in September, the organization’s head said this week at a press conference. If the vaccine proves safe and capable of stimulating relevant immune responses, NIAID plans in the first quarter of 2017 to launch what he called a phase 2b study—which would enroll thousands of volunteers—“in a country that has a very high rate of infection.”Now that you’ve got the scoop on this week’s hottest Science news, come back Monday to test your smarts on our weekly quiz!center_img Sign up for our daily newsletter Get more great content like this delivered right to you!
