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.
Introducing: the new conspiracy age
Everything is a conspiracy theory now. Conspiracists are all over the White House, turning fringe ideas into dangerous policy. America’s institutions are crumbling under the weight of deep suspicion and the lasting effects of covid isolation. Online echo chambers are getting harder to escape, and generative AI is altering the fabric of truth. A mix of technology and politics has given an unprecedented boost to once-fringe ideas—but they are pretty much the same fantasies that have been spreading for hundreds of years.
MIT Technology Review helps break down how this moment is changing science and technology—and how we can make it through. We’re thrilled to present The New Conspiracy Age, a new series digging into how the present boom in conspiracy theories is reshaping science and technology.
To kick us off, check out Dorian Lynskey’s fascinating piece explaining why it’s never been easier to be a conspiracy theorist. And stay tuned—we’ll be showcasing a different story from the package each day in the next few editions of The Download!
Four thoughts from Bill Gates on climate tech
Bill Gates doesn’t shy away or pretend modesty when it comes to his stature in the climate world today. “Well, who’s the biggest funder of climate innovation companies?” he asked a handful of journalists at a media roundtable event last week. “If there’s someone else, I’ve never met them.”
The former Microsoft CEO has spent the last decade investing in climate technology through Breakthrough Energy, which he founded in 2015. Ahead of the UN climate meetings kicking off next week, Gates published a memo outlining what he thinks activists and negotiators should focus on and how he’s thinking about the state of climate tech right now. Here’s what he had to say.

One more thing

How scientists want to make you young again
A little over 15 years ago, scientists at Kyoto University in Japan made a remarkable discovery. When they added just four proteins to a skin cell and waited about two weeks, some of the cells underwent an unexpected and astounding transformation: they became young again. They turned into stem cells almost identical to the kind found in a days-old embryo, just beginning life’s journey.
At least in a petri dish, researchers using the procedure can take withered skin cells from a 101-year-old and rewind them so they act as if they’d never aged at all.
Now, after more than a decade of studying and tweaking so-called cellular reprogramming, a number of biotech companies and research labs say they have tantalizing hints that the process could be the gateway to an unprecedented new technology for age reversal. Read the full story.
