The Download: biotech’s future and cheaper, cleaner steel

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.

Meet the under-35s shaping the future of biotech

Every year, MIT Technology Review puts together our 35 Innovators Under 35, a list of some of the brightest and best young minds working across science and technology. This year’s honorees include nine people transforming biotech, whose work spans everything from lifesaving innovations to groundbreaking longevity tech.

Their innovations include a “reprogramming” therapy that reverses vision loss, tiny brain electrodes inspired by Japanese art, and a personalized gene-editing treatment for a baby with a rare genetic disorder. There are even efforts to design new viruses with generative AI, which (hopefully) will produce new drugs or soak up pollution.

Get to know the biotech innovators behind these breakthroughs.

Biotechnology is one of four categories in our 35 Innovators Under 35 list for 2026, featuring young people worldwide doing groundbreaking work in science and technology. Meet the rest of them here, or explore the full list across the AI, computing and robotics, biotechnology, and climate and energy categories.

This founder is making cheaper, cleaner steel

The steel industry isn’t exactly known for innovation. Very little has changed about purifying iron ore since the process was invented and commercialized in the 1850s. But Laureen Meroueh, founder of Hertha Metals, has an idea that could change that.

Meroueh may have found a way to clean up steelmaking without driving up the price. Her new furnace turns iron ore into refined liquid steel in a single step and swaps coal for natural gas. Together, those changes slash emissions by at least half, she says, and cut costs by 25% compared with steelmaking as usual.

Here’s how she plans to make steel cleaner without making it more expensive.

Laureen Meroueh is one of the climate change and energy honorees on our 35 Innovators Under 35 list.

Quote of the day

“I didn't ask Facebook to build a profile of my family—I posted a video of me singing in the car with my kids.” 

—Kalie Roberts, a travel content creator, says in an Instagram reel that Meta AI used years of Facebook posts to piece together her children’s identities and pinpoint where her family lives.

One more thing

Chinese tech workers are starting to train their AI doubles—and pushing back

In April, a GitHub project called Colleague Skill struck a nerve by claiming to “distill” a worker’s skills and personality—and replicate them with an AI agent. Though the project was a spoof, it prompted a wave of soul-searching among otherwise enthusiastic early adopters.

A number of tech workers told MIT Technology Review that their bosses are already encouraging them to document their workflows for automation via tools like OpenClaw. Many now fear that they are being flattened into code and losing their professional identity.

In response, some are fighting back with tools designed to sabotage the automation process. Read the full story on their battle with clone workers.
