The Download: where gene editing goes next

Plus: OpenAI paid workers in Kenya less than $2 an hour to label toxic language for ChatGPT

Gene editing for the masses is coming

We know the basics of healthy living by now. A balanced diet, regular exercise, and stress reduction can help us avoid heart disease—the world’s biggest killer. But what if you could take a vaccine, too? And not a typical vaccine—one shot that would alter your DNA to provide lifelong protection?

That vision is not far off, researchers say. Advances in gene editing, and CRISPR technology in particular, may soon make it possible.

Gene editing may be finally ready to go mainstream, treating many diseases and conditions—and not all of them genetic. In the future, we might be able to use the same approach to protect people from high blood pressure and diabetes, and dramatically improve their quality of life in the process. Read the full story.

These scientists used CRISPR to put an alligator gene into catfish

What’s happened? Millions of fish are farmed in the US every year, but many of them die from infections. In theory, genetically engineering fish with genes that protect them from disease could help to address the issue. A team of scientists have attempted to do just that—by inserting an alligator gene into the genomes of catfish.

Why an alligator gene? The alligator gene codes for a protein called cathelicidin which is antimicrobial, according to the team at Auburn University in Alabama. In theory, it could make animals that have the gene artificially inserted into their genomes more resistant to diseases.

Did it work? The resulting fish do seem to be more resistant to infections. But while the scientists hope to eventually get their transgenic catfish approved so that it can be sold and eaten, they’re facing a long and complicated process. Read the full story.

Finding a new life for old batteries

Batteries are key to both electric vehicles and energy storage on the grid. If we want more EVs on our roads and more renewable energy, we’ll also need more batteries.

This new demand presents two related problems. First, we need to find enough metals to make all those batteries—and mining can be destructive for people and the environment, as well as downright expensive. Secondly, since batteries will last a finite amount of time, they’ll eventually become trash that we’ll need to deal with.

Recycling these old batteries could be the missing piece of the equation. It’s just a matter of whether we can pull it off. Read the full story.

The big story

Inside the enigmatic minds of animals

October 2022

More than ever, we feel a duty and desire to extend empathy to our nonhuman neighbors. In the last three years, more than 30 countries have formally recognized other animals—including gorillas, lobsters, crows, and octopuses—as sentient beings.

A trio of books from Ed Yong, Jackie Higgins, and Philip Ball, detail creatures’ rich inner worlds and capture what has led to these developments: a booming field of experimental research challenging the long-standing view that animals are neither conscious nor cognitively complex.

But though all three assemble troves of fascinating research that provides windows into the lives of animals, we’re left asking how close we really are to bridging the species divide. Read the full story.
