It's time for "Nerd News," covering the most important news for your brain you may have missed over the last few days.Here's a quick rundown of this week in science . . .
1.Astronomers scanned 1,300 of the closest stars looking for signals that might be ALIENS trying to contact us.And they found . . . nothing.(In other space news:NASA snapped a cool photo of an asteroid from less than half-a-mile away.)
2.Pretty soon, Alexa will be able to tell if you're having a HEART ATTACK, just by listening for abnormal breathing.Then she could call for help and save your life.
3.A new study found dogs can detect lung cancer with 97% accuracy, just by using their sense of smell.(We also saw a study this week that found dogs developed their sad "puppy dog eyes" just to manipulate humans better.)
4.Researchers in Minnesota created a robotic arm for amputees that you control with your mind.And it doesn't require any implants or surgeries.You just stick something on your head, and it links up with your brain.
5.Scientists at Penn created a new type of reversible superglue by studying how snails stick to walls.Just a small dab of it can hold about 200 pounds.
6.And earlier this week, we found out the small, autonomous sub the Internet named "Boaty McBoatface" made a major scientific discovery on his very first mission.
