The Washington Post reports that Jim O'Neill will replace Susan Monarez as head of the CDC. O'Neill is a longevity enthusiast who has supported deregulation of drugs and the idea of creating new jurisdictions at sea. Here's my recent profile: www.technologyreview.com/2025/06/30/1...

The world's "oldest baby" has just been born: a big welcome to the world to baby Thaddeus, who developed from an embryo that was in storage for 30 and a half years www.technologyreview.com/2025/07/29/1...

I met with Bryan Johnson recently. He told me about his plans to start a new religion where "the body is God" (and how it stems from his fears of an AI "event horizon") www.technologyreview.com/2025/05/05/1...

When Joyce Esser, who has motor neuron disease, used her AI voice clone to tell her husband to "get his arse in gear," she was temporarily banned from using it.

Should tech companies be screening or limiting what people like Joyce can say? www.technologyreview.com/2025/02/14/1...

Motor neuron diseases can rob people of their voices. But AI is bringing them back. AI voice clones are helping people with MND communicate, and hear their old voices again.

Humanlike "teeth" have been grown in mini pigs

Researchers mixed human and pig tooth cells and grew them in the lab, then implanted them into the jaws of living mini pigs. They formed little bioengineered teeth!

Goal is to make replacement teeth for ppl

We're creating more IVF embryos than ever, and millions of them are ending up frozen in suspended animation for years or decades.

Some will be used to start pregnancies, or donated for research. But many of them will be stuck in limbo. Indefinitely.

Bird flu presents a "high threat with indeterminate risk," according to a public health specialist I spoke to this week. Flu viruses have a pretty horrific track record when it comes to pandemics.

In the US, H5N1 is spreading through dairy cows, there have been 66 cases confirmed in people...

Engineers can make computer models of your organs, and some doctors are already using them to decide which bits of people's hearts to burn off in surgery(!)

Wow TIL this is what a mouse uterus looks like

Bird flu is still spreading in the US. The virus is in 675 cattle herds (that we know of), and is showing up in dairy produce. There are 55 reported cases in people so far. And we still don't even know how the virus is spreading.

It's not looking great... www.technologyreview.com/2024/11/29/1...

It's ten years since the first birth following a uterus transplant. But since then, only around 135 transplants been performed. It's still a new procedure, and uteruses are a scarce resource. So who should get one? www.technologyreview.com/2024/11/22/1...

Fascinating piece by the brilliant @eileenguo.bsky.social about Clear, a company that is helping people in the US skip airport queues but wants to expand into other areas of daily life... in exchange for your face www.technologyreview.com/2024/11/20/1...

So I watched The Substance last week and feel pretty confident some of those images will be burned into my mind forever.

It got me thinking about the impacts of problematic thinking about women. Especially the use of the term "women of childbearing age" www.technologyreview.com/2024/11/15/1... 🧪
