A.I. can't wear socks

🧠 College professors just exposed ChatGPT’s biggest essay flaw

Apparently, “vibes” still matter in academia.

A new study found that college professors can sniff out A.I.-written essays with scary precision. Well, scary if you’re a student or an A.I. trying to pass as human. Researchers gave professors 145 student-written essays and 145 ChatGPT-generated ones on the same topics and the bots bombed. Why? Despite flawless grammar and structure, or possilby because of it, the A.I. essays read like a Wikipedia page with a caffeine addiction.

The dead giveaway: human essays used engagement techniques like rhetorical questions, personal asides, and actual persuasive language. ChatGPT? Just the facts, ma’am. Turns out, even the smartest models still can’t fake voice.

Professors aren’t mad, they’re just… disappointed. Because the real loss isn’t the grade, it’s the thinking. And that’s a skill no algorithm can replicate (yet).

🧦 Science says wearing socks to bed improves your sleep

My wife already knew this.

This might ruffle some sleep purists, but… socks for the sleep win: Wearing socks to bed helps you sleep measurably better. A 2018 study found that people who wore socks fell asleep 8 minutes faster, slept 32 minutes longer, and woke up less often through the night.

And no, it’s not just about cozy toes. It’s science. Warming your feet helps your blood vessels dilate, which cools your core body temperature, one of the signals your body uses to say, “hey, let’s shut it down for the night.” Also, when you touch your husband with your ice toes, he won’t wake you up with yelps of “Geeze, Ang, why are your feet so cold!”

According to sleep experts, this is the same logic behind taking a warm shower before bed: heat up a bit to cool down more effectively. It’s like a weird sleep cheat code your nervous system appreciates.

So, if you’re tossing and turning, it might be time to swallow your pride and slide on those bedtime socks. Please. I’m begging you. I mean… science says it works.

📰 Bill Gates reveals the 1997 article that changed the course of his life

It shocked him, moved him, and shaped one of the most powerful philanthropic efforts on Earth.

In a recent GatesNotes post, Bill Gates shared the exact moment he realized his wealth had to serve more than innovation. The spark? A 1997 article by journalist Nicholas Kristof titled “For Third World, Water Is Still a Deadly Drink.”

The piece revealed that diarrhea, a disease most in the West consider inconvenient at worst, was quietly killing over 3 million people a year, most of them children. “We were shocked,” Gates wrote. “That seemed like a problem we could help with.”

That one story planted the seed for a mission. The Gates Foundation has since donated billions to global health, with a special focus on eradicating diarrheal disease in children. Vaccines, sanitation research, and healthcare access, all because one reporter told the truth clearly enough for someone powerful to listen.

Kristof called it “the most important article I ever wrote.” Gates called it “life-changing.” You might just call it journalism with a purpose.

Bonus: Gates also says Kristof’s new memoir Chasing Hope belongs on your must-read list—and explains why it might just change your outlook too.

That’s Tuesday’s GOOD stuff! Enjoy your movie! I mean… oh no… I’ve done it again.
