g Life - With a new planet-wide analysis of vertebrate life, an international team has used 21st century science to update an iconic 1876 map of Earth’s zoological regions. See article.
g Intelligence - Got milk? Ancient European farmers who made cheese thousands of years ago certainly had it. But at that time, they lacked a genetic mutation that would have allowed them to digest raw milk's dominant sugar, lactose, after childhood. See article.
g Message - When talk turns to SETI, there’s one question that’s as common as catfish: "We’re not broadcasting to the aliens; so what makes you think they’ll be broadcasting to us?" See article.
