　　　 Researchers combing the rainforests of Brazil have uncovered four new species of fungi that turns ants into zombies(僵尸). Although it is not the first time the first time the has been seen affecting ants, the discovery of four distinct species highlights the level of biodiversity in the Amazon.

　　　 The study, led by Assistant Professor David Hughes of the University of Pennsylvania, appears online in the journal PLoS One.

　　　 Ants become infected when they come into contact with spores(孢子) released by the fungus. Within a week the ant enters a “zombie-like” state. “This so-called zombie fungus changes the behaviors of the ant, causing it to die in an exposed position,” the study authors write. The fungus then grows outof the head of the ant, releasing spores into the air, which rain down onto unsuspecting ants and the forest floor.

　　　 In 2009, Hughes led a team of researchers studying “zombie-ants” in Indonesia. They found the infected ants consistently attached to leaves 25 centimeters (9.8 inches) above the ground in an environment with 95 percent humidity(湿度)-perfect conditions for the fungus to grow.

　　　 In the current study, Hughes and colleagues found each species of fungus was different in size and shape, and adapted to live only in one particular species. Two of the species of fungus have also adapted to grow secondary spores, doubling their chances of finding a new host.

　　　 Steve Shattuck, an ecologist with CSIRO Ecosystem Sciences says there are records of the fungus existing in Australia, but its range is limited to tropical(热带的) regions of Australia.

　　　 “It’s hard to find. Exactly how common it is, who knows? But obviously if it was too common it would kill all the ants and then go away,” says Shattuck.

　　　 And despite the fungus’ ability at destroying a whole colony of ants, Shattuck says its potential for use in pest control is very limited.

　　　 “What the paper found was that the fungi were species specific,” he sys. “So unless one of ants was your pest it doesn’t do you any good.”

　　　 It also means the possibility that the fungi will turn our 2000 species of Australian ant into a zombie army is highly remote.

　　　 We’ve all been there, finishing a whole bag of chips out of boredom or downing cookie after cookie while cramming for a big test. But when done a lot-especially without realizing it-emotional eating can affect weight, health, and overall well-being.

　　　 Not many of us make the connection between eating and our feelings. But understanding what drives emotional eating can help people take steps to change it.

　　　 One of the biggest myths about emotional eating is that it's prompted by negative feelings. Yes, people often turn to food when they're stressed out, lonely, sad, anxious, or bored. But emotional eating can be linked to positive feelings too, like the romance of sharing dessert on Valentine's Day or the celebration of a holiday feast.

　　　 Sometimes emotional eating is tied to major life events, like a death or a divorce. More often, though, it's the countless little daily stresses that cause someone to seek comfort or distraction in food.

　　　 Emotional eating patterns can be learned: A child who is given candy after a big achievement may grow up using candy as a reward for a job well done. A kid who is given cookies as a way to stop crying may learn to link cookies with comfort. It's not easy to "unlearn" patterns of emotional eating. But it is possible. And it starts with an awareness of what's going on.

　　　 We’re all emotional eaters to some extent (who hasn’t suddenly found room for dessert after a filling dinner?). But for some people, emotional eating can be a real problem, causing serious weight gain.

　　　 The trouble with emotional eating (aside from the health issues) is that once the pleasure of eating is gone, the feelings that cause it remain. And you often may feel worse about eating the amount or type of food you did. That’s why it helps to know the differences between physical hunger and emotional hunger.

　　　 Next time you reach for a snack, check in and see which type of hunger is driving it.
