The Download: Flock’s new rules, cloning’s future, and children’s cells — MIT Technology Review | AIPROPX

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.

Flock is tightening its rules in response to a growing surveillance backlash

The police-tech giant Flock is changing officers’ access to its nationwide network of license plate readers. The move comes amid a backlash over mass surveillance and reports of officers using the technology to stalk and harass current or former romantic partners.

To combat that, the company will require them to enter a criminal case number before searching its database and expand automated auditing of suspicious searches. But because Flock won’t verify those case numbers, officers could still find ways around the safeguards.

Here’s what Flock is changing—and where loopholes remain .

Cloning could be used to save species—or make human “organ sacks”

—Jessica Hamzelou

This week I spoke to scientists who have found a way to turn male mouse embryos female. They’ve developed a CRISPR-based approach to essentially cut out the Y chromosome. It allowed them to create female clones of male mice .

They hope their approach could be helpful in conservation efforts, especially in cases where we might have only a few individuals of a species left. But cloning has multiple uses, ranging from genetically modifying livestock to recreating beloved pets and potentially even creating “brainless” replicas of humans.

Find out what cloning can do now, and where it could lead next .

This scientist is helping build a missing map of childhood

In 2017, Deanne Taylor attended a presentation about the Human Cell Atlas, an ambitious attempt to map every cell in the human body. Taylor was floored, and then concerned. The project’s researchers had only made plans to study adults. “That’s when my little alarm went off,” she says. “Not again.”

Children’s cells are different from grownups’ cells in the way they express genes, which can cause drastically different and even deadly responses to drugs that adults tolerate well. Taylor has since pushed the Human Cell Atlas to include children and is working on a major database of healthy pediatric tissue.

The goal is to give researchers a baseline for how children develop—and potentially reveal how diseases that emerge in adulthood begin much earlier.

Quote of the day

“ They were incredibly sloppy. If you’re serious about this, your AI shouldn’t be able to break out onto the internet and then do it again right afterward.”

—A former OpenAI employee tells Wired that the company’s rogue agent hack was a watershed moment for AI safety and cybersecurity.

One More Thing

AI materials discovery now needs to move into the real world

Startups flush with cash are building AI-assisted laboratories to find materials far faster and more cheaply. But they’re still waiting for their ChatGPT moment.

By far the most time-consuming and expensive step in materials discovery is not imagining new structures but making them in the real world. Before synthesizing a material, you don’t know if it can actually be made or whether it will have the properties you want.

Now startups like Lila Sciences and Periodic Labs are building labs where AI agents can design experiments, control robots, and analyze results, potentially shortening the discovery process from decades to a few years or less.

Discover what it will take to turn AI’s predictions into real materials .
