North Korea deployed a ballistic missile test that traveled 430 miles toward South Korea, landing in the Sea of Japan after about 30 minutes of airtime, BBC reports.

Why it matters: South Korea just elected a new president last week, Moon Jae-in, whose stance on North Korea was a little controversial — he's said he wants more open dialogue with them, which is a significant shift from the strict relationship they've had over the past 10 years.

What they're saying: Jae-in reportedly held an emergency meeting with his security council to discuss the ballistic missile launch.

One quick note: In a statement, the U.S. Pacific Command said that the missile didn't appear to be an intercontinental ballistic missile (IBCM), which would have the capacity to reach the U.S.

Jason Chaffetz is reportedly considering taking a "substantial" on-air role with Fox News as early as July, the Washingtonian reported.

Their sources: Two GOP lawmakers "who have spoken to Chaffetz directly" and four House Republican aides.

Don't forget: Chaffetz announced in April he would not seek re-election for his spot as Utah Representative or as House Oversight Committee chairman. He made the announcement the same day Fox News officially cut ties with Bill O'Reilly.

Why it matters: If the reports are confirmed (Fox News did not respond to Axios' request for comment), it could signal the network's hope to maintain their right-leaning brand, especially amid criticism that they're moving too far to the left.

One controversial Chaffetz quote: "So maybe, rather than getting that new iPhone that they just love and they want to go spend hundreds of dollars on, maybe they should invest that in health care."

Although he once said anyone who wants to keep migrants out of their country "is not Christian," Pope Francis said today he won't try to get Trump to soften his tone when they meet on May 24, per AP.

Pope Francis told reporters he'd listen respectfully to Trump, but that he'd also share his candid opinions with him during their meeting. He wants to find "doors that are at least a little bit open" so that he can find common ground with Trump.

"I never make a judgment about a person without hearing him out," the pope said.

The Huffington Post's Jonathan Cohn does a deeper dive on the comments I reported in Friday's Vitals newsletter from OMB director Mick Mulvaney, who questioned whether health care should be considered a right because some people just don't take care of themselves.

Reality check: Cohn notes that the research suggests that people's behavior accounts for no more than half of all medical problems, and probably less. He also quotes a statement by the American Diabetes Association criticizing Mulvaney's remarks: "All of the scientific evidence indicates that diabetes develops from a diverse set of risk factors, genetics being a primary cause."

Why it matters: There's actually a lot of discussion in the public health community about how to reduce preventable diseases. But Mulvaney's comments may set that discussion back by playing down the role of diseases that people get due to genetics or simple bad luck.

This post has been updated to correct Cohn's affiliation. He is with the Huffington Post.

A 22-year-old British cybersecurity researcher thwarted yesterday's "Wanna Decryptor 2.0" cyber attack that affected computers worldwide by spending nearly $11, the Washington Post reports.

The "kill switch": The cybersecurity expert figured out there was a hidden "kill switch" (an unregistered domain) within the malware that was locking users out of their computers. By buying a domain ending with "gwea.com" and registering a website, all for $10.69, he was able to activate the hidden kill switch — potentially saving companies worldwide billions of dollars.

Despite market optimism about the Trump agenda, Barron's sees (paywall) "modest" growth this year and next.

"Hopes for an Economic Trump Jump Look Overblown: Netted out, the negatives and positives of the president's proposals don't point to any acceleration in GDP expansion," by columnist Gene Epstein:

The U.S. economy under President Barack Obama expanded at the tepid annual rate of 2.1%, the slowest since World War II. The Trump administration claims that growth can now accelerate to 3% to 4%. In the dicey world of forecasting, almost nothing can be ruled out. But, sad to say, between now and the end of 2018 at least, the net effect of Trump and his policies should result in the economic expansion continuing at the same dismal pace.

Going to the dentist can be a pain, but it was certainly much tougher 13,000 years ago when dental work could have started, according to a recent study published in the American Journal of Physical Anthropology.

The dental details: Italian researchers recently analyzed a pair of 13,000-year-old incisors (think: your front four teeth and the four opposite on the bottom row) that were discovered 20 years ago. The images of the incisors show large, hollowed pits in the teeth that had previously been filled, which indicates some dental work had been done. Although the exact filling composition is hard to discern now, the researchers found traces of bitumen, vegetable fibers and hair.

Why it matters: This research, although not the oldest finding of dental work, is the oldest example of the use of fillings. It indicates that even prehistoric humans were curious and concerned about dental health and began curative practices for cavities.
