The world’s first industrial-scale plant for green steel promises a cleaner future
As of 2023, nearly 2 billion metric tons of steel were being produced annually, enough to cover Manhattan in a layer more than 13 feet thick.
Making this metal produces a huge amount of carbon dioxide. Overall, steelmaking accounts for around 8% of the world’s carbon emissions—one of the largest industrial emitters and far more than such sources as aviation.
A handful of groups and companies are now making serious progress toward low- or zero-emission steel. Among them, the Swedish company Stegra stands out. The startup is currently building the first industrial-scale plant in the world to make green steel. But can it deliver on its promises? Read the full story.

2025 is a critical year for climate tech
—Casey Crownhart
I love the fresh start that comes with a new year. And one thing adding a boost to my January is our newest list of 10 Breakthrough Technologies.
As I was looking over the finished list this week, I was struck by something: While there are some entries from other fields that are three or even five years away, all the climate items are either newly commercially available or just about to be. It’s certainly apt, because this year in particular seems to be bringing a new urgency to the fight against climate change. It’s time for these technologies to grow up and get out there.

A New York legislator wants to pick up the pieces of the dead California AI bill
The first Democrat in New York history with a computer science background wants to revive some of the ideas behind the failed California AI safety bill, SB 1047, with a new version in his state that would regulate the most advanced AI models.
Assembly member Alex Bores hopes his bill, currently an unpublished draft that MIT Technology Review has seen, will address many of the concerns that blocked SB 1047 from passing into law last year. Read the full story.

MIT Technology Review Narrated: How covid conspiracy theories led to an alarming resurgence in AIDS denialism
Podcaster Joe Rogan, former presidential candidate Robert F. Kennedy Jr, and football quarterback Aaron Rodgers are all helping revive AIDS denialism—a false collection of theories arguing either that HIV doesn’t cause AIDS or that there’s no such thing as HIV at all.
These ideas were initially promoted back in the 1980s and ’90s but fell out of favor, as more and more evidence stacked up against them, and as more people with HIV and AIDS started living longer lives thanks to effective new treatments. But then coronavirus arrived.

The big story
The weeds are winning
October 2024
Since the 1980s, more and more plants have evolved to become immune to herbicides. This threatens to decrease yields, and in extreme cases can wipe out whole fields.
At worst, it can even drive farmers out of business. It’s the agricultural equivalent of antibiotic resistance, and it keeps getting worse. Agriculture needs to embrace a diversity of weed control practices. But that’s much easier said than done. Read the full story.
