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 dinosaur news:  A “virtually complete” stegosaurus fossil is going up for auction this summer, and could sell for $6 million.  Some people aren’t happy about it and think it belongs in a museum.

2.  In “it’s so loud in here” news:  A team at the University of Wisconsin invented A.I.-powered headphones that let you hear a single person in a crowd just by looking at them.

3.  In food news:  A study found regularly feeding your toddler peanuts might prevent them from developing a peanut allergy . . . and a study in Belgium found eating chocolate cake might damage our DNA.

4.  In alien news:  Someone at an air show in New York may have caught a UFO on video . . . or it’s just a balloon.

5.  And in other space news:  The launch of Boeing’s manned Starliner mission is set for tomorrow after multiple delays . . . the James Webb telescope found the oldest known galaxy again. . .

astronauts might be able to live underground on Mars in old lava tubes . . . and the sunspot that caused the big Northern Lights show this month could cause another solar storm next week.  But it probably won’t extend quite as far south.
