Good technology should change the world

January 12, 2026
The billionaire investor Peter Thiel (or maybe his ghostwriter) once said, “We were promised flying cars, instead we got 140 characters.” That quip originally appeared in a manifesto for Thiel’s venture fund in 2011. All good investment firms have a manifesto, right? This one argued for making bold bets on risky, world-changing technologies rather than…

Meet the new biologists treating LLMs like aliens

January 12, 2026
How large is a large language model? Think about it this way. In the center of San Francisco there’s a hill called Twin Peaks from which you can view nearly the entire city. Picture all of it—every block and intersection, every neighborhood and park, as far as you can see—covered in sheets of paper. Now…

How next-generation nuclear reactors break out of the 20th-century blueprint

January 12, 2026
Commercial nuclear reactors all work pretty much the same way. Atoms of a radioactive material split, emitting neutrons. Those bump into other atoms, splitting them and causing them to emit more neutrons, which bump into other atoms, continuing the chain reaction.  That reaction gives off heat, which can be used directly or help turn water…

Hyperscale AI data centers: 10 Breakthrough Technologies 2026

January 12, 2026
In sprawling stretches of farmland and industrial parks, supersized buildings packed with racks of computers are springing up to fuel the AI race. These engineering marvels are a new species of infrastructure: supercomputers designed to train and run large language models at mind-­bending scale, complete with their own specialized chips, cooling systems, and even energy…

Sodium-ion batteries: 10 Breakthrough Technologies 2026

January 12, 2026
For decades, lithium-ion batteries have powered our phones, laptops, and electric vehicles. But lithium’s limited supply and volatile price have led the industry to seek more resilient alternatives. A sodium-ion battery works much like a lithium-ion one: It stores and releases energy by shuttling ions between two electrodes. But unlike lithium, a somewhat rare element…

The Download: the case for AI slop, and helping CRISPR fulfill its promise

January 9, 2026
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. How I learned to stop worrying and love AI slop —Caiwei Chen If I were to locate the moment AI slop broke through into popular consciousness, I’d pick the video of rabbits bouncing…

A new CRISPR startup is betting regulators will ease up on gene-editing

January 9, 2026
Here at MIT Technology Review we’ve been writing about the gene-editing technology CRISPR since 2013, calling it the biggest biotech breakthrough of the century. Yet so far, there’s been only one gene-editing drug approved. It’s been used commercially on only about 40 patients, all with sickle-cell disease. It’s becoming clear that the impact of CRISPR…

America’s new dietary guidelines ignore decades of scientific research

January 8, 2026
The new year has barely begun, but the first days of 2026 have brought big news for health. On Monday, the US’s federal health agency upended its recommendations for routine childhood vaccinations—a move that health associations worry puts children at unnecessary risk of preventable disease. There was more news from the federal government on Wednesday,…
