Will the real Anthropic please stand up?

After weeks of frenzied speculation, Anthropic has filed its IPO prospectus. The 335-page document (100 pages or so are focused on risks) lays out the company’s unique view of the technology it is building and how it believes it will change the world.

But Anthropic has been honing its storytelling skills for years. Its public messaging is a master class in narrative capture, presenting it as different things to different people: an AI safety organization, a profit-driven megacorp, and a group hell-bent on creating superhuman technology.

These roles come with huge tensions. Will the IPO reveal the company behind the mask, or lean deeper into the myth-making? Take a new glimpse inside Anthropic .

How solid-state transformers could help power the AI boom

Transformers are a crucial but nearly invisible part of the US grid, helping efficiently move power across long distances. But they’re complicated and in short supply, and their basic design hasn’t changed much in about a century.

As electricity demand rises from EVs, data centers, and more, researchers and companies are looking to modernize these grid staples. Solid-state versions could help ease supply concerns and cut power losses.

The technology is still in development, but it could become a crucial part of our future grid.

Find out how solid-state transformers could help meet rising electricity demand .

Are we there yet? Exercise in a pill

We all know exercise is good for us. It builds muscle, strengthens bones, lowers blood pressure, and boosts mood. By deciphering how movement benefits the body, researchers hope to develop medicines that can offer some of the same perks, without the workout.

The idea isn’t to replace exercise but to bring its upsides to people who struggle with frailty, disability, or chronic illness.

Discover how close researchers are to developing an exercise pill .

This story is part of “Are we there yet?” from the new Impossible issue of MIT Technology Review . The series takes stock of six technologies that have long promised to change the world—and scores them on a progress meter. Over the next six days, we’ll explore each one in The Download.

#### The problem with thinking you’re part Neanderthal

There’s a theory that many of us have an “inner Neanderthal.” The idea is that Homo sapiens and its cousin species once bred, leaving some people today with a trace of Neanderthal DNA.

This DNA is arguably the 21st century’s most celebrated discovery in human evolution. But in 2024, a pair of French geneticists called into question the theory's very foundations.

They proposed that what scientists interpret as interbreeding could instead be explained by population structure—the way genes concentrate in smaller, isolated groups.

Find out what it all means for human evolution .
