The Earth formed relatively quickly from the cloud of dust and gas around the sun, trapping water and gases in the planet’s mantle, according to research published Dec. 5 in the journal Nature. Apart from settling Earth’s origins, the work could help in identifying extrasolar systems that could support habitable planets.
Three UC Davis geochemists who improved our understanding of Earth and the solar system will be honored at the Geochemical Society’s 2016 Goldschmidt Conference in Yokohama, Japan, on June 30 and July 1. This is the first time in the history of the Geochemical Society that three researchers from the same institution will receive society honors in the same year.
Rock soil droplets formed by heating most likely came from Stone Age house fires and not from a disastrous cosmic impact 12,900 years ago, according to new research from the University of California, Davis. The study, of soil from Syria, is the latest to discredit the controversial theory that a cosmic impact triggered the Younger Dryas cold period.
