It’s Primary Day in Florida, where the weather is hot, the politics are messy and the Republican Party has become a dominant force. Follow the latest updates and the election results as they come in. Polling has been limited, so there may be some surprises.

A newly gerrymandered map added four Republican-leaning House seats in Florida, but Republicans still appear worried about a district northeast of Orlando, where Cory Mills is seeking re-election despite assault claims. In one of the remaining few blue-leaning seats, Black Democrats are seeking to unseat Debbie Wasserman Schultz, an incumbent who decided to run in a historically Black congressional district.

Floridians will also be weighing in on a new governor, because Ron DeSantis is term-limited. Byron Donalds, a House Republican, has President Trump’s endorsement. He is expected to be a heavy favorite against David Jolly, the front-runner among the Democrats.

It’s also Primary Day in Alaska, where the state’s nonpartisan Senate primary will offer a rare chance to test the strength of the two leading candidates. Both Dan Sullivan, the Republican incumbent, and Mary Peltola, a well-funded Democratic challenger, are almost certain to be among the four candidates to advance. But it will be interesting to see which of them gets more votes, and whether the other Dan Sullivan — no relation — will qualify as well. (We flew to a tiny Alaskan fishing village to track down the lesser-known Sullivan.)

It’s crunch time for U.S.-Canada trade

At midnight tonight, the U.S. is set to impose 50 percent tariffs on tens of billions of dollars of select Canadian exports, including hockey sticks and cheese.

Negotiators from both sides have said they are trying to work out a deal before the deadline. A proposal of terms hammered out over the past few days was handed to Trump this afternoon, a U.S. official said.

Oil giants push to expand reserves outside Middle East

Saudi Arabia and the United Arab Emirates are seeking to hold substantially more of their oil stockpiles in Japan — perhaps as much as 10 times the roughly eight million barrels each now holds there. Officials from both countries have also discussed expanding their reserves in South Korea.

The plans are one of several ways Gulf exporters are looking to protect their supplies from the instability of the Middle East, where the prolonged U.S.-Iran conflict has made it more difficult to ship fuel. In recent days, two ships in the Strait of Hormuz were attacked, killing at least one sailor.

In other news from the Middle East: Israeli pressure on the West Bank has sent the occupied territory to the brink of financial collapse.

Meta is back on trial over social media addiction claims

The attorneys general of California, Colorado, Kentucky and New Jersey have accused Meta — which owns Instagram and Facebook — of fueling a national youth mental health crisis with technology designed to be addictive like cigarettes. Together, the states are seeking roughly $200 billion in damages.

The trial, which began today in Oakland, Calif., is the first bellwether federal case over child harm. Meta denies the claims and argues that it protects young users. But social media giants have already taken losses in smaller state and local cases; one woman who said she was harmed by social media was awarded $6 million.

The U.S. energy grid is perhaps the most complex machine ever built. The thousands of transformers required for it, many of them aging, can weigh 400 tons and take years to build. Taking out just nine substations, where many are situated, could black out the country. The Times Magazine took an in-depth look at how vulnerable this system is.

A battered theater industry turns to ‘Les Miz’

Productions of “Les Misérables,” the musical based on Victor Hugo’s 1862 novel, are popping up at regional theaters across the country — in Arizona, California, Colorado, Georgia, Illinois, Kansas, Kentucky, Maryland and New York, to name a few.

A major tour ended in June, making the show finally available to license. And “Les Miz” (as it is affectionately called) sells lots of tickets, providing a boost to theaters when so many are in difficult financial straits. Our theater reporter Michael Paulson recently attended a performance inside a hot Utah canyon with 2,300 others.

We’re not the only ones who like furry companions

Nonhuman primates like monkeys and apes share more in common with us than you might think. According to a new study, that includes the desire to take care of a pet.

The researchers examined 88 primate species and found that every one of them exhibited some behavior that could be linked to pet-keeping. There was a monkey that formed a bond with a chicken, others that got close with deer, and a gorilla that appeared to adopt a kitten.

A DNA test reveals that two childhood friends are sisters

Meena Geltink and Minal Tijssen were teenagers when they met at an event for adopted children. Both were born in India and grew up with adoptive families not far from each other in the Netherlands. They quickly struck up a friendship, but drifted apart in adulthood.

Two decades later, the women have reconnected after learning from a genealogy website that they were actually sisters separated at birth. Geltink said she “burst into tears” when she learned; it had been nearly 10 years since she submitted her DNA sample. Last week, after reuniting in a Dutch park, Tijssen said, “I don’t feel alone anymore.”

Have an emotional evening.
