    Plants

    Plant growth patterns changing on much of Earth’s surface

    When beetles munch plants bearing their RNA, genes the bugs need to survive are turned off.

  5. ice cream bar
    Health & Medicine

    Additives that keep foods fresh may sour in the gut

    Additives called emulsifiers that are used in ice cream and other foods weaken the intestines’ defenses against bacteria, causing inflammation in mice.
