Deepfakes of your dead loved ones are a booming Chinese business

Once a week, Sun Kai has a video call with his mother, and they discuss his day-to-day life. But Sun’s mother died five years ago, and the person he’s talking to isn’t actually a person, but a digital replica he made of her—a moving image that can conduct basic conversations. They’ve been talking for a few years now.

There are plenty of people like Sun who want to use AI to preserve, animate, and interact with lost loved ones as they mourn and try to heal. The market is particularly strong in China, where at least half a dozen companies are now offering such technologies and thousands of people have already paid for them.

But some question whether interacting with AI replicas of the dead is truly a healthy way to process grief, and it’s not entirely clear what the legal and ethical implications of this technology may be. Still, if only 1% of Chinese people can accept AI cloning of the dead, that’s still a huge market. Read the full story.

How I learned to stop worrying and love fake meat

Fixing our collective meat problem is one of the trickiest challenges in addressing climate change—and for some baffling reason, the world seems intent on making the task even harder.

The latest example occurred last week, when Florida governor Ron DeSantis signed a law banning the production, sale, and transportation of cultured meat across the Sunshine State. 

The good news is the world is making some real progress in developing meat substitutes that increasingly taste like, look like the traditional versions, whether they’ve been developed from animal cells or plants. 

If they catch on and scale up, it could make a real dent in emissions—with the bonus of reducing animal suffering, environmental damage, and the spillover of animal disease into the human population. The bad news is we can’t seem to take the wins when we get them. Read the full story.

The way whales communicate is closer to human language than we realized

The news: Sperm whales are fascinating creatures. They possess the biggest brain of any species, and are highly social. But there’s also a lot we don’t know about them, including what they may be trying to say to one another when they communicate using a system of short bursts of clicks, known as codas. Now, new research suggests that sperm whales’ communication is actually much more expressive and complicated than previously thought.

How they did it: Researchers used statistical models to analyze whale codas and managed to identify a structure to their language that’s similar to features of the complex vocalizations humans use. Their findings represent a tool future research could use to decipher not just the structure but the actual meaning of whale sounds. Read the full story.

The big story

Novel lithium-metal batteries will drive the switch to electric cars 

February 2021

For all the hype and hope around electric vehicles, they still make up only about 2% of new car sales in the US, and just a little more globally.

For many buyers, they’re simply too expensive, their range is too limited, and charging them isn’t nearly as quick and convenient as refueling at the pump. All these limitations have to do with the lithium-ion batteries that power the vehicles.

But QuantumScape, a Silicon Valley startup is working on a new type of battery that could finally make electric cars as convenient and cheap as gas ones. Read the full story.
