Autonomous robots, sequencers, and machine-learning algorithms are revolutionizing humanity’s ability to catalog Earth’s unstudied species, Marion Renault reports. But many of those species could be lost before we ever meet them: theatlantic.com/science/2025…

"We are too few, studying too many things." Taxonomists are racing to name millions of unnamed species before they vanish, lost before we ever meet them. My latest — on the burning library of life — for @TheAtlantic : theatlantic.com/science/2025…

Dementia is the disease of our era—not just medical, but existential. For @TheAtlantic I reviewed Jennie Erin Smith's new book, "Valley of Forgetting," and explored how language betrays our deepest fears about memory and selfhood. theatlantic.com/books/archiv…

In Starr County, Texas, Alzheimer’s disease affects about one in five people on Medicare—more than double the national rate. I unpacked what we know (and what we don't) about one of America's dementia hotspots for @TheAtlantic: theatlantic.com/health/archi…

I love these 1936 newsreel clips of Zdeněk Koubek, a Czech track star who publicly transitioned gender after his transition, he came to New York to perform on Broadway. this seems to be the only surviving video Koubek is the center of my book, THE OTHER OLYMPIANS — out June 4!

new: plastic producers have known for 30+ yrs that recycling is not an economically or technically feasible plastic waste management solution. but they promoted it anyway, a new @climatecosts analysis shows. the report is full of new docs & evidence. theguardian.com/us-news/2024…

my mamie denise has left us. she died peacefully, accompanied, without pain. I can't find the words for all that she taught me. I can only say that I would not love the way I do, or conceive of love the way I do, without her. and I will never stop missing her.

Calls/emails from reporters asking for a comment on last's years temperature are coming earlier than normal this year. Time to dust off my "last year was hot" auto-response.

It’s easy to treat the media as a punching bag. But look to the nation’s local newsrooms. For little money or recognition, reporters in 2023 stood up to power brokers who tried to bully them into silence, exposed corrupt officials and even saved lives. Proof, from every state:

big thank you to @jfballenger — not only for sharing his perspective w/ @99piorg, but for his book, Self, Senility, and Alzheimer's Disease in Modern America it's a 💡cultural history of Alzheimer's disease in the U.S. since the late 19th century. press.jhu.edu/books/title/37…
