This Week in Science: Killer Coffee, Contagious Yawns, and Oceans on Mars

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.  In space news:  We found huge oceans of water on Mars, or technically IN Mars.  It’s too deep to get to.

2.  In caffeine news:  A study found more than four cups of coffee or two energy drinks a day could cause heart damage.

3.  In A.I. news:  A study in England found things like ChatGPT don’t actually pose a serious threat to society.  So we should all chill out and stop worrying about A.I. destroying humanity.

4.  In “I swear I’m not tired” news:  A study mapped the neural pathways that cause you to yawn when you see someone else yawn.

5.  In climate change news:  Scientists developed a new way of producing “super-wood” that stores more carbon and reduces emissions.  (Careful!  Yeah, I’ve got some super-wood . . . in my pants.)

6.  In “how’d they do that” news:  A study found the six-ton “Altar Stone” at Stonehenge likely came from 500 miles away in Scotland.

7.  And in bug news:  A study found bug sprays meant to deter cockroaches don’t work well anymore.  They’ve evolved past them.  The term “super-roaches” is being tossed around.
