An Ignoble Experiment: The 7: Why many Americans may face a hunger crisis; dramatically cheaper insulin; TikTok’s screen-time limits; and more

Good morning. It's Thursday, March 2, and these "historical" American Girl dolls — from 1999 — are making us feel very old. Now let's catch up.

Over what? The Senate passed a bill yesterday to revoke a Labor Department rule that allows (but doesn't require) retirement fund managers to make investments based on criteria like climate change.
What that means: A two-thirds majority of Congress would be needed to override a veto.

What to know: President Volodymyr Zelensky praised efforts to maintain energy and heat despite Russian attacks, and Ukrainians marked their first day of spring on social media.
Why it matters: Russian forces had hoped to use the winter season to weaponize energy and win the war in Ukraine. Their focus will now move to an expected spring offensive.

What is Havana syndrome? A mysterious ailment that began affecting U.S. diplomats and intelligence officers in 2016. It caused a range of symptoms, including memory lapses.
What the report found: That it's "very unlikely" the syndrome was caused by a foreign enemy with a secret energy-wave weapon, something many people suspected.
The bigger picture: The findings are at odds with another expert report released last year. This may be the official U.S. word on the mystery, but it probably won't end the debate.

Why? A federal pandemic food benefit, which gave more money to SNAP recipients, ended yesterday.
What this means: Even though grocery prices remain high, lower-income families may get only $6 per person each day for food. That's less than what many experts say is necessary for a healthy diet.

The details: Eli Lilly is capping out-of-pocket insulin costs at $35 a month and cutting prices of its most commonly prescribed insulin by 70%, the company said yesterday.
Why this matters: Insulin is a treatment many diabetics need to survive, and it can cost $6,000 a year or more for people without good health insurance.

The details: The Memphis Grizzlies guard allegedly hit and flashed a gun at the boy last summer. Days earlier, a mall worker accused him of threats, police records show.
What happened then? Morant, 23, said he punched the teen in self-defense, according to records obtained by The Post. No charges were filed in either incident.

The details: Users who have identified themselves as younger than 18 will get a message when they hit an hour of daily scrolling. To dismiss it, they'll have to enter a passcode.
Will it work? Probably not. Beyond the ability to enter a passcode, teens have been known to misrepresent their ages to dodge features meant for kids.
