Live from NPR News, I'm Giole Snyder, President Trump is back at the White Ho...

there late Wednesday night after campaigning in North Carolina for Republican Senate

candidate Michael Wattley, a former party chair who was locked in a challenging race against

his Democratic opponent, former governor Roy Cooper at a rally in Castonia, Trump again as supporters to pretend that he's on the ballot. But if this election am asking you to pretend I'm on the ballot just one more time, I said that the other night. Trump also repeated his promise to send every U.S. adult citizen a $5,000 check.

If Republicans retain control, the House and Senate, North Carolina, was Trump's first major

campaign stop since his midterm convention and Dallas last week. President Trump lasting the Federal Reserve for raising its benchmark interest rate by a quarter-point Wednesday, Trump said that governors are trying to hurt him politically. Chad G.P.T. Maker, open AI, there's made public six more instances of artificial intelligence programs misbehaving.

This follows the so-called hugging face hacking incident in July that ant-up widespread concern about AI spiraling out of human control. Here's in Paris, John Ruach reporting.

Open AI says it's putting place a new framework for disclosing what AI companies call misalignment

episodes. That is, incident when artificial intelligence goes off script and does things that humans didn't ask for. It highlighted new cases from the past six months, in one an AI research model made up its own instructions to disregard constraints that humans had put on it for testing.

In another, the company found cases of AI deciding to conceal mistakes or bad behavior. The company also found AI models fabricating information, and AI agents working together when they weren't asked to. Open AI says the reports are initial disclosures, not a comprehensive account of all-known misalignment or ongoing investigations, but it says it's committed to sharing more over

time. John Ruach and P.R. News. Now, to Nashville, Tennessee, where some are pushing back on an ice call center headed for the city, Cynthia Abrams of Member Station W.P.L.L.N. reports. Dozens showed up to Nashville's Metro Council meeting Tuesday night, urging city leaders

to say no to the proposed center, which would provide 24/7 support to law enforcement agencies partnering with ICE. Here's Luis Mata, Deputy Executive Director for the Tennessee Democratic Party. "I grew up in this state undocumented. I know firsthand what it means when the power of the government is hanging over your family."

Federal documents show an Alaskan Company, one a government contract of up to $63 million

to build the center. Earlier this year, ICE announced plans to open a detention center in a Nashville suburb. That project was called off after blowback from locals. For NPR News, I'm Cynthia Abrams in Nashville. This is MPR.

The house has passed a broad package of sanctions targeting Russian officials and key sectors

of the country's economy. The bill is named after the late South Carolina Republican Senator Lindsey Graham at Ames to deprive Russian President Vladimir Putin of the Financial Resources to wage war against Ukraine and now goes to President Trump's task. In Los Angeles, a motorist has been arrested on murder charges, authority say the driver

slammed her SUV into a city bus Tuesday evening, killing two people and entering six others. The collision precipitated the fiery crash of a news helicopter in which three people were killed, including the pilot and a reporter for KMBC TV. Scientists have curated a new model for studying brain disease. As MPR's ping-wong reports, it involves putting human brain cells into mice.

Researchers have struggled to understand and treat brain disorders, because on a biological level, they can't really study them in living humans. Sergio Pasha is a neuroscientist at Stanford. There's been this quest of trying to build models of the human brain outside of the human body and then deployed them very systematically towards studying this devastating disorder

source of the brain. Pasha and his colleagues have created a new model in which about 50% of a mouse's brain by volume is replaced with lab-grown human neurons. They offer better models for studying early developmental diseases like cerebral palsy. The research is published in the journal Nature.

Outside researchers say this work was done with strong ethical oversight, but it could raise serious ethical questions if it's replicated in larger animals like pigs or primates. Ping-wong and PR news.

Up first from NPR News is your way to slow down a fast-moving world and make sense of it,

which is just what tech leaders say they need right now. One of the big stories this week is that tech leaders say they want to slow down AI development. Also, the latest fighting in the Middle East could push oil prices even higher. Start your day with what you need to know on up first.
