3. President Trump widened U.S. sanctions against trade with North Korea and presented a united front against its nuclear program with Prime Minister Shinzo Abe of Japan, above left, and President Moon Jae-in of South Korea. They had lunch on the sidelines of the U.N. General Assembly.
Meanwhile, the North’s foreign minister compared Mr. Trump’s warnings at the U.N. to “the noise of a dog barking.”
More details emerged about how Mr. Trump intends to handle the Iran nuclear deal, which some say is an important signal to North Korea. Administration officials say he will seek to toughen its terms rather than scrap it right away.
4. Facebook said it was submitting 3,000 Russia-linked ads to the congressional committees investigating election interference.
Twitter, which has kept a low profile since Facebook’s disclosure, said it would brief the Senate Intelligence Committee on Wednesday behind closed doors.
Both platforms are now also entangled in the investigation by Robert Mueller, the special counsel, and facing the possibility of future regulation of political advertising. Above, Mark Zuckerberg of Facebook.
5. Aaron Hernandez, the former New England Patriots tight end who committed suicide in April while serving a life sentence for murder, had a severe form of C.T.E., the degenerative brain disease linked to head trauma.
Researchers said it was “the most severe case they had ever seen in someone of Aaron’s age,” according to his lawyer. He was 27. The disease has been found in more than 100 former N.F.L. players.
6. A sense of euphoria has swept Iraqi Kurdistan ahead of a referendum set for Monday on independence from Iraq.
But Iraq’s central government, the U.S. and various other regional power brokers — even the U.N. — want it canceled, warning that it could unleash ethnic violence, tear Iraq apart and fracture the coalition fighting the Islamic state.
The Kurdish leadership insists the vote will proceed. And we learned that they even hired Paul Manafort, the former Trump campaign manager at the center of the Russia investigation, to help pull it off.
7. Good news: Sea turtles appear to be bouncing back worldwide.
One of the authors of a new study on the creatures says conservation efforts dating to the 1950s have paid off, a tale of “cautionary optimism.”
The researchers found that even small populations are capable of growing if they’re protected.
8. Our critic loved the new art show “Pacific Standard Time: LA/LA” — so much so that he was moved to proclaim, “I guess there’s a God.”
The sprawling exhibition, at 70 institutions throughout Southern California, focuses on the cultural exchange between Latin America and Los Angeles.
“During one of the meanest passages in American national politics within living memory, we’re getting a huge, historically corrective, morale-raising cultural event,” he wrote. “It’s a gift, worth a trip to puzzle over and savor.”

9. Liliane Bettencourt, the L’Oréal heiress ranked by Forbes this year as the richest woman in the world, died at 94.
The jet-setting socialite’s later years were marked by a scandal that captivated France. It began in 2007, when Mrs. Bettencourt’s daughter accused a younger man of bamboozling her aging mother for cash, fine art and an island in the Seychelles.
The probe expanded to the political sphere, and the authorities even investigated charges that former President Nicolas Sarkozy had manipulated her into financing his 2007 campaign. (The inquiry was later dropped.)
10. Finally, how do families around the world spend their vacation?
This week’s Times Magazine is the “Voyages” issue, which takes you around the globe with a handful of families vacationing in their own countries.
There was a Caribbean-themed water park in China, an Eid al-Adha celebration in Guinea, and a hike through former FARC territory in Colombia. Above, a festival in Japan. Should be ample inspiration to start dreaming about your next trip.
Have a great night.
