What’s next for carbon removal?

After years of growth that spawned hundreds of startups, the nascent carbon removal sector appears to be facing a reckoning.

Running Tide, a promising aquaculture company, shut down its operations last summer, and a handful of other companies have shuttered, downsized, or pivoted in recent months as well. Venture investments have flagged. And the collective industry hasn’t made a whole lot more progress toward Running Tide’s ambitious plans to sequester a billion tons of carbon dioxide by this year.

The hype phase is over and the sector is sliding into the turbulent business trough that follows, experts warn.

And the open question is: If the carbon removal sector is heading into a painful if inevitable clearing-out cycle, where will it go from there? Read the full story.

An AI app to measure pain is here

This week I’ve also been wondering how science and technology can help answer that question—especially when it comes to pain.

In the latest issue of MIT Technology Review’s print magazine, Deena Mousa describes how an AI-powered smartphone app is being used to assess how much pain a person is in.

The app, and other tools like it, could help doctors and caregivers. They could be especially useful in the care of people who aren’t able to tell others how they are feeling.

But they are far from perfect. And they open up all kinds of thorny questions about how we experience, communicate, and even treat pain. Read the full story.

One more thing

We’ve never understood how hunger works. That might be about to change.

When you’re starving, hunger is like a demon. It awakens the most ancient and primitive parts of the brain, then commandeers other neural machinery to do its bidding until it gets what it wants.

Although scientists have had some success in stimulating hunger in mice, we still don’t really understand how the impulse to eat works. Now, some experts are following known parts of the neural hunger circuits into uncharted parts of the brain to try and find out.

Their work could shed new light on the factors that have caused the number of overweight adults worldwide to skyrocket in recent years. And it could also help solve the mysteries around how and why a new class of weight-loss drugs seems to work so well. Read the full story.
