Research says you might want to change what you wear, or don't, to bed

It might be time to reevaluate your nighttime sleep attire.
You’ve binged your show, done your doom scroll, and now it’s time to hit the sack. But do you cozy up in flannel jammies or go full birthday suit?
As Erik Barnes explores in this story, the debate over bedtime nudity goes way back, possibly to the dawn of clothing itself. Now, science is weighing in, with sleep experts like Dr. Michael Breus (aka the Sleep Doctor) offering fresh reasons to rethink your nighttime wardrobe. From oxytocin boosts to toddler interruptions, there’s a surprising number of factors that might affect whether you snooze clothed or not.
“I paid for 400 threads. I'm going to use them all.”
The full article breaks down the pros, the cons, and the very relatable Reddit opinions about what we wear, or don’t, between the sheets.

Now that’s a sharp-dressed yak! This photo by Dennis G. Jarvis was taken in the Himalayan region of South Central Asia, but don’t be fooled, they don’t all dress this well.
Home insurance rates up by 76% in some states
Over the last 6 years, home insurance rates have increased by up to 76% in some states. Between inflation, costlier repairs, and extreme weather, premiums are climbing fast – but that doesn’t mean you have to overpay. Many homeowners are saving hundreds a year by switching providers. Check out Money’s home insurance tool to compare companies and see if you can save.

Riddle me this, Batman! Who funded the research?
Look, not every research project needs complex words and world-altering implications. Sometimes, someone with an advanced degree and access to a university’s resources and staff (and presumably a costume department) just wants to know if having Batman around makes people change their behavior. That person was Professor Francesco Pagnini of the Università Cattolica del Sacro Cuore in Milan and his team.
“Our findings are similar to those of previous research linking present-moment awareness (mindfulness) to greater prosociality.”
As Erik Barnes shares, the setup was simple, put a pregnant woman on a crowded train and see how often she’s offered a seat. Then, (and I love typing this!) have Batman show up. The results were shockingly definitive; the number of people who offered up a seat nearly doubled in the presence of the caped crusader. But, why? That’s when the real research began, and the answers are fascinating, Robin… fascinating.
Kaprekar’s Constant is both a fun party trick and a fascinating bit of mathematical trivia.
If you’ve been around a teen recently, you’ve been hearing a lot of “Six, seven!” followed by inscrutable laughter and the waggling of hands. Why? I have no idea. Teens are weird (that’s just science).
If you prefer your numbers to be fascinating, as opposed to infuriating, Ryan Reed has a story about one of math’s most curious four-digit numbers, Kaprekar’s Constant. Though it does feature both a six and a seven, the number is actually the inevitable result of a simple algorithm.
Sure, it doesn’t have a ton of practical uses (yet?), but it’s a delightfully weird reminder that even in chaos, math finds a way.
On November 29, 1972, a little circle moving on a screen kicked off a revolution that would create a multi-hundred-billion-dollar industry. If you’re thinking of the yellow guy that chases ghosts, you’re not thinking back far enough. Pong debuted 53 years ago, and entertainment was forever changed. Handcrafted by Allan Alcorn, the game was both revolutionary and absurdly simple. The first hardware didn’t even have a CPU. A modern PC would be able to run north of a million instances of the game at once, but finding that many paddle controllers could prove challenging. The original game debuted at Andy Capp’s Tavern in Sunnyvale, and was said to have been so popular that the coin-box jammed.
As an aside, Alcorn’s other claim to fame was hiring a young Steve Jobs, launching another tech career that would change things forever.
