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.

Coming soon: MIT Technology Review’s 15 Climate Tech Companies to Watch

For decades, MIT Technology Review has published annual lists highlighting the advances redefining what technology can do and the brightest minds pushing their fields forward.

This year, we’re launching a new list, recognizing companies making progress on one of society’s most pressing challenges: climate change.

MIT Technology Review’s 15 Climate Tech Companies to Watch will highlight the startups and established businesses that our editors think could have the greatest potential to address the threats of global warming. And attendees of our upcoming ClimateTech conference will be the first to find out. Read the full story.

ClimateTech is taking place at the MIT Media Lab on MIT’s campus in Cambridge, Massachusetts, on October 4-5. You can register for the event, either in-person or online, here.

We know remarkably little about how AI language models work

AI language models are not humans, and yet we evaluate them as if they were, using tests like the bar exam or the United States Medical Licensing Examination.

The models tend to do really well in these exams, probably because examples of such exams are abundant in the models’ training data. Now, a growing number of experts have called for these tests to be ditched, saying they boost AI hype and fuel the illusion that such AI models appear more capable than they actually are.


These discussions (raised in this story last week) highlight just how little we know about how AI language models work and why they generate the things they do—and why our tendency to anthropomorphize can be problematic. Read the full story.

The big story

The quest to learn if our brain’s mutations affect mental health

August 2021

Scientists have struggled in their search for specific genes behind most brain disorders, including autism and Alzheimer’s disease. Unlike problems with some other parts of our body, the vast majority of brain disorder presentations are not linked to an identifiable gene.

But a University of California, San Diego study published in 2001 suggested a different path. What if it wasn’t a single faulty gene—or even a series of genes—that always caused cognitive issues? What if it could be the genetic differences between cells?

The explanation had seemed far-fetched, but more researchers have begun to take it seriously. Scientists already knew that the 85 billion to 100 billion neurons in your brain work to some extent in concert—but what they want to know is whether there is a risk when some of those cells might be singing a different genetic tune.
