A 9-Month Cruise Is TikTok’s Favorite New ‘Reality Show’

In the last few months, Beth Fletcher, a 39-year-old photographer in Derbyshire, England, built a small following on TikTok by recapping and analyzing the British reality show “I’m a Celebrity … Get Me Out of Here!” When the latest season ended in early December, Ms. Fletcher was at a loss for content because, she said, “we don’t have another good reality TV show on until summer.”Then the TikTok algorithm delivered: a video of Brooklyn Schwetje, a graduate student and influencer, sharing a day in her life on the Ultimate World Cruise, a nine-month-long, round-the-world voyage with Royal Caribbean.

Asian American Officials Cite Unfair Scrutiny and Lost Jobs in China Spy Tensions

When Thomas Wong set foot in the United States Embassy in Beijing this summer for a new diplomatic posting, it was vindication after years of battling the State Department over a perceived intelligence threat — himself.Diplomatic Security officers had informed him when he joined the foreign service more than a decade ago that they were banning him from working in China. In a letter, he said, they wrongly cited the vague potential for undue “foreign preference” and suggested he could be vulnerable to “foreign influence.”Mr. Wong had become a U.S. diplomat thinking that China was where he could have the…

The First Secret Asteroid Mission Won’t Be the Last

For generations, Western space missions have largely occurred out in the open. We knew where they were going, why they were going there and what they planned to do. But the world is on the verge of a new era in which private interests override such openness, with big money potentially on the line.Sometime in the coming year, a spacecraft from AstroForge, an American asteroid-mining firm, may be launched on a mission to a rocky object near Earth’s orbit. If successful, it will be the first wholly commercial deep-space mission beyond the moon. AstroForge, however, is keeping its target asteroid…
