| We’re covering the Brexit uproar in London, Hurricane Dorian’s slow march of destruction and wind-tunnel tests for geese. | | By Andrea Kannapell | | | Protesters on both sides of the Brexit divide gathered outside Parliament on Tuesday. Andrew Testa for The New York Times | | | The prime minister made good on his threat to call a snap general election immediately after Parliament won the power to try to stop a “no deal” withdrawal from Britain. | | | There is little time left before the Brexit deadline of Oct. 31. Parliament would have to agree to the election. | | | Defectors: A group of “Conservative rebels” from Mr. Johnson’s party, starchy grandees who just months ago held the reins of power, joined the effort to thwart the prime minister. | | | One Conservative lawmaker, Phillip Lee, actually quit the party, writing that it had “become infected by the twin diseases of English nationalism and populism.” | | | Carrie Lam, the Hong Kong chief executive, said at her weekly news conference on Tuesday that even though "my personal emotions are fluctuating greatly" she did not intend to step down. Lam Yik Fei for The New York Times | | | The territory’s dispirited chief executive, Carrie Lam, is insisting that she is not ceding to protesters’ demands that she step down, even though an audio recording emerged of her telling local businesspeople last week that she yearned to resign. | | | But if she tried, our reporting shows, China’s leaders would almost certainly stop her, fearing the move would be read as a sign of weakness that would only encourage more of the pro-democracy, anti-Beijing protests that have roiled Hong Kong for months. | | | First person: Andrew Higgins, our Moscow correspondent, is a longtime China hand. He returned to Hong Kong recently after many years away, and was struck by the loss of what, before the British handover in 1997, had been a “deeply felt role as a place inextricably tied to the rest of China, not just economically but intellectually and emotionally.” | | | A dock in the Bahamas.

Here’s the latest. | | | Who's next: Rain is pelting Florida, and forecasts put the hurricane “dangerously close” to the coast in coming hours, where it is expected to move slowly northward along Georgia and South Carolina. By the end of the week, it is expected to be shadowing the coasts of North Carolina and Virginia. We mapped it. | | | Laerke Posselt for The New York Times | | | Denmark leaned into the reality that Silicon Valley is a global superpower, assigning it an ambassador: Casper Klynge, 46, a career diplomat who has worked in some of the world’s most turbulent places. | | | PAID POST: A MESSAGE FROM CAMPAIGN MONITOR | | Email Marketing 101: Never Sacrifice Beauty for Simplicity | | A drag-and-drop email builder, a gallery of templates and turnkey designs, personalized customer journeys, and engagement segments.

If the talks fail, Iran has said it will escalate its nuclear activity starting Friday. | | | Huawei: The Chinese technology giant accused the American government of using F.B.I. harassment, entrapment and cyberattacks to hound its employees and disrupt its operations. The F.B.I. declined to comment, but the U.S. has a track record of using cyberoperations to fish out information about the company. | | | Snapshot: Above, a researcher testing bar-headed geese in a wind tunnel at the University of British Columbia. The newly published results of the study help reveal how “the astronauts of the bird world” manage their oxygen-poor migrations over the Himalayas. | | | U.S. Open: Daniil Medvedev, 23, has been trolling the tennis crowds in New York, to his advantage. He just won his first Grand Slam quarterfinal, beating Stan Wawrinka. Serena Williams and Roger Federer also play today. We’ll have live updates here. | | | Obituary: Nie Yuanzi, 98, who helped write a vitriolic “big-character poster” that won Mao’s blessing. For the rest of her life, she wrestled with fame and infamy. | | | Jim Wilson/The New York Times | | | Smarter Living: Unlike many physical illnesses or disabilities, mental illness isn’t always visible. In the workplace, anti-discrimination laws can provide some protections, but they go only so far. So you need a strategy, whether it’s communicating with your boss about reasonable accommodations or, as our writer puts it, “giving yourself space to cry into your lunch for no good reason and coming back to your work when you’re ready.” | | | And Julia Moskin, our food reporter, has guidance for home cooks on the murky world of olive oil (in short, seek the freshest and use it generously). | | | Just another gorgeous Icelandic landscape, with sheep and possibly unseen creatures.
