An Ignoble Experiment: The 7: Deadly tornadoes in Tennessee; gene-editing breakthrough; a dinosaur’s last meal; and more

Good morning. It's Monday, Dec. 11, and this story about a 17-year-old who passed the bar exam is making us feel old. Now let's catch up.

What to know: Health care in Gaza is "on its knees," the World Health Organization said yesterday, amid spreading diseases and the threat of mass starvation.
U.S. response: The Biden administration has called for Israel to protect civilians, but vetoed a U.N. resolution demanding a cease-fire Friday and will provide more weapons to Israel.

What happened? Liz Magill was criticized after she declined to state plainly that a call for genocide against Jews would violate the University of Pennsylvania's code of conduct.
Why it matters: Saturday's resignation has reinvigorated the debate about free speech and where colleges draw the line between offensive speech and threatening conduct.

What happened? The tornadoes touched down around Nashville on Saturday. Dozens were injured and thousands were left without power. (See photos of the damage here.)
On the East Coast: The same weather system caused a significant storm yesterday, raising the risk of travel delays into the start of the workweek.

In April: Jack Teixeira, a 21-year-old Massachusetts Air National Guard member, was charged after allegedly sharing hundreds of documents on the popular online chat platform.
What's new? A Post investigation shows how he allegedly used his privileged access to obtain classified files, and reveals missed opportunities to potentially catch him earlier.

Who? The conspiracy theorist and Infowars founder who falsely claimed that the 2012 Sandy Hook school mass killing was "staged." He was banned from the platform in 2018.
What it means: The move, the result of a Musk poll, will probably hasten the flight of advertisers from the site (formerly known as Twitter) over hateful content.

What is sickle cell disease? A genetic illness that can cause excruciating pain and cut decades off people's lives. The therapies were approved Friday.
It's historic: One of the therapies is the first commercially available treatment in the U.S. based on gene-editing technology, potentially opening a new era in medicine.

What you're looking at: A fossil of Gorgosaurus, a smaller cousin of the T. rex, with the partially digested drumsticks of two birdlike dinosaurs where its stomach once was.
It's pretty amazing: The discovery, revealed Friday, is the first of its kind. It opens a window into the behavior and diet of a predator that lived 75 million years ago.
