This Week in Science: Dirty Toilets, Psychopaths, and Killing Google

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.  A team at University of Colorado used lasers to show how many water droplets get ejected by public toilets when we flush.  And the answer is A LOT.  They posted a video on how they can reach five feet in the air.

2.  A study on the “Napoleon Complex” found shorter men tend to have more traits associated with psychopaths.

3.  A new online tool called Asteroid Launcher lets you see how much damage a big one would do if it hit close to where you live.  Also, an asteroid the size of a bus “just missed” us yesterday by 1.2 million miles.  But according to the site, something that small would probably explode miles above the ground.

4.  In other space news:  The Mars helicopter set a new altitude record of 46 feet.  It was its 35th flight in less than 20 months, and it’s got another one tomorrow.  NASA originally hoped it would last 30 days.

5.  And in A.I. news:  A new chatbot called ChatGPT is so good at answering questions, experts think it could make Google obsolete in the next few years.
