The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real human embryos reach after approximately 14 days of development. It even secreted hormones that turned a drugstore pregnancy test positive. To Jacob Hanna’s expert eye, the model wasn’t perfect—more like a rough sketch. It had no chance of developing into an actual baby. But in 2022, when two students burst into his office and dragged him to a microscope to show him the cluster…

When Clark Giles first heard about ticks making people allergic to meat, he found the notion so unbelievable, he considered it “hogwash.” Then, in 2022, it happened to him. Following a spate of tick bites, he ate a hamburger and went into sudden anaphylaxis. His lips became numb, his face swollen, and his skin a “red carpet from my knees to my shoulders,” he says. Eventually, Giles—who raises sheep on a homestead in Oklahoma—had to give up eating not just beef but pork, and, yes, even lamb. From there, his allergy started to manifest in stranger ways. During lambing season,…

Recently, in a few cities across the country, Starbucks quietly unveiled a pair of drinks, one resembling a pistachio milkshake, the other a mossy sludge. Unlike with green beverages already on the Starbucks menu, their hue does not come from matcha, mint, or grapes. They are green because they contain actual greens—or, at least, a dried and powdered form of them sold by the supplement company AG1. Now getting a hefty dose of vegetables—including, but not limited to, broccoli, spinach, and, uh, “grasses”—is as easy as ordering an iced AG1 Coconutmilk Blend or its sibling, the Watermelon Blend. Powdered greens…

Produced by ElevenLabs and News Over Audio (NOA) using AI narration. The first person who taught me something about death and defiance was the mother of a family friend, an older woman who had moved from Punjab to the United States to be closer to her son. I remember her as delicate and draped always in pastel salwar kameezes. After she was diagnosed with breast cancer, which moved quickly to claim her bones and her brain, her desire to return to Punjab intensified. When my parents told me about the end of her life, it was with a mixture of…

Of the first three elements to appear after the Big Bang, only one is available to buy as a bath soak. The Sads Smashing Anti-Stress Bath Treatment, which comes in shiny silver packaging, lists lithium as an ingredient and promises to take users “from weighed down to mellowed out.” It’s one of dozens of over-the-counter lithium supplements that claim to support a healthy mood. The metal is also an ingredient in Novos Core, a supplement marketed to “target the 12 root causes of aging,” plus in Life Extension, XtendLife, LifeLink, Youngevity, and AgeImmune. The anti-aging entrepreneur Bryan Johnson’s “Essential” multivitamin…
