It’s time for “Nerd News,” covering the most important news for your brain.

Here’s a quick rundown of this week in science . . .

1.  Researchers may have found the genetic quirk that made our early ancestors stop growing tails.  They think it happened around 25 million years ago.

2.  Don’t like fruit?  A study found even just smelling it might help prevent cancer and other diseases.

3.  In other food news:  Eating too much junk food increases your risk for 32 different diseases.  And researchers are working on a new sensor that can tell how fresh meat is, so you’ll know if it’s still safe to eat.

4.  In space news:  The private moon lander that touched down last week suffered a broken leg and is already dead.  It stopped responding yesterday but still made history.  It’s the first time a private company has landed something up there.

5.  And finally:  There’s more going on around Uranus than we thought.  Astronomers found another moon, plus two more moons orbiting Neptune.  Neptune now has 16 that we know of, and Uranus has 28.
