The Download: replacing animal testing, and underwater drones

This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology.

Is this the end of animal testing?

Animal studies are notoriously bad at identifying human treatments. Around 95% of the drugs developed through animal research fail in people, but until recently there was no other option.

Now organs on chips, also known as microphysiological systems, may offer a truly viable alternative. They're triumphs of bioengineering, intricate constructions furrowed with tiny channels that are lined with living human tissues that expand and contract with the flow of fluid and air, mimicking key organ functions like breathing, blood flow, and peristalsis, the muscular contractions of the digestive system.

It's only early days, but if they work as hoped, organs on chips could solve one of the biggest problems in medicine today. Read the full story.

How underwater drones could shape a potential Taiwan-China conflict

A potential future conflict between Taiwan and China would be shaped by novel methods of drone warfare involving advanced underwater drones and increased levels of autonomy, according to a new war-gaming experiment by the think tank Center for a New American Security (CNAS).

Since Russia invaded Ukraine in 2022, drones have been aiding in what military experts describe as the first three steps of the kill chain"-finding, targeting, and tracking a target-as well as in delivering explosives. Drones like these would be far less useful in a possible invasion of Taiwan. Instead, a conflict with Taiwan would likely make use of undersea and maritime drones to scout for submarines.

Should social media come with a health warning?

Earlier this week, the US surgeon general, also known as the nation's doctor," authored an article making the case that health warnings should accompany social media. The goal: to protect teenagers from its harmful effects.

But the relationship between this technology and health isn't black and white. Social media can affect users in different ways-often positively. So let's take a closer look at the concerns, the evidence behind them, and how best to tackle them. Read the full story.

The big story

The first babies conceived with a sperm-injecting robot have been born

April 2023

Last spring, a group of engineers set out to test the sperm-injecting robot they'd designed. Altogether, the robot was used to fertilize more than a dozen eggs.

The result of the procedures, say the researchers, was healthy embryos-and now two baby girls, who they claim are the first people born after fertilization by a robot."

The startup behind the robot, Overture Life, says its device is an initial step toward automating IVF, and potentially making the procedure less expensive and far more common than it is today. But that will be far from easy. Read the full story.
