Weighing divorce, airline etiquette, your brain’s development: Check out the day’s stories

By Sarah Hutter, CNN

👋 Welcome to 5 Things PM! Thanksgiving chats usually cover politics, football and movies — but this year, expect a new hot topic: AI. Wondering why everyone’s buzzing about it and what you should know? Dive into this explainer.

Here’s what else you might have missed during your busy day.

5 things

1️⃣ Out with the old

Sometimes ringing in the new year means letting go of old ties. If you’ve already decided that divorce is on the horizon for 2026 — or you’re still weighing your options — taking a few steps now can help ease financial stress later.

2️⃣ Exploring extreme depths

A hidden canyon in the Mediterranean is teeming with whales and dolphins, but it’s now under threat. After years of conducting research at the surface level, an ambitious team built a specialized, remotely operated vehicle to uncover what lies on the seafloor.

3️⃣ Clashing legacy

More than a century ago, soldiers who fought at Wounded Knee were given Medals of Honor. The awards still divide their descendants.

4️⃣ Stark gender bias

Frida Kahlo’s self-portrait just sold for $54.7 million — making it the most valuable work by a female artist at auction. It’s a triumph, but also a reminder of the persistent gender gap in the art world.

5️⃣ Mind your manners

You adjust your neck pillow, slip on a sleep mask and settle in for a long flight, only to be interrupted by feet poking out from behind your armrest. With 6 million US travelers expected to fly domestically this Thanksgiving, here are some tips for navigating the etiquette of air travel.
