Show Me The Science Month Day 17 Often when something new crops up in evolutionary history, it's usually the result of tinkering with functional, preexisting molecular tools.. In a paper published in Science, some NYU researchers find that the protein cues used by fruit fly embryos to direct their migrating reproductive cells are processed by some very ancient cellular machinery. The scientists test their ideas with a very weird experiment: they use their newfound knowledge to direct the reproductive cells to migrate into the embryos' brains. read more
