This Week in Science: Hangry Insects, a Fifth Ocean, and Dreams vs. the Future
It’s time for “Nerd News,” covering the most important news for your brain you may have missed. Here’s a quick rundown of this week in science . . .
1. In school, you learned there are four oceans: The Atlantic, Pacific, Indian, and Arctic Ocean up north. But this week, “National Geographic” added a FIFTH ocean to its maps. The Southern Ocean is the body of water around Antarctica. They say it deserves its own name because the currents are so different.
2. A new sleep study found dreams might be our brain’s way of trying to process old memories . . . to help us predict the FUTURE. But not in a paranormal way. They think your brain might just be trying to anticipate things that are coming up.
3. In health news: A study at the University of Chicago found that low doses of laughing gas might be an effective treatment for depression.
4. In space news: Three new unmanned missions to Venus are now in the works . . . the Mars helicopter had its seventh successful flight . . . and NASA’s Juno satellite got some great fly-by shots of Jupiter’s largest moon, Ganymede.
5. It’s crazy that this was just a theory until now: Physicists at the University of Iowa finally proved this week that the Northern Lights are caused by electromagnetic waves.
6. And in insect news: Researchers at Oxford found that even fruit flies get “hangry” when they haven’t eaten in a while.
