Science Magazine: Hunting microbe wields a “gatling gun” harpoon

Biologists sometimes use the phrase “arms race” to describe an evolutionary tug-of-war, but it’s rarely this literal. Microbes called dinoflagellates (above) have developed intricate weapons—including a microscopic version of a Gatling gun—to harpoon their dinners, a new study shows.
