The Download: lab-grown meat’s climate impact, and Congress’ AI plans

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.

Here’s what we know about lab-grown meat and climate change

Soon, the menu in your favorite burger joint could include not only options made with meat, mushrooms, and black beans but also patties packed with lab-grown animal cells. Not only did the US just approve the sale of cultivated meat for the first time, but the industry is in the process of raising billions of dollars to bring its products to restaurants and grocery stores. 

In theory, that should be a big win for the climate—greenhouse-gas emissions from the animals we eat account for nearly 15% of the global total. But whether cultivated meat really is better for the environment is still not entirely clear. Read the full story.

Three things to know about how the US Congress might regulate AI

Two weeks ago, Senate majority leader Chuck Schumer announced his grand strategy for AI policymaking at a speech in Washington, DC, ushering in what might be a new era for US tech policy. He outlined some key principles for AI regulation and argued that Congress ought to introduce new laws quickly.

Schumer’s plan is a culmination of many other, smaller policy actions, and is part of a recent flurry of AI-related activity. Tate Ryan-Mosley, our senior tech policy reporter, has identified three key themes in all this chatter that you should know to help you understand where US AI legislation could be going.

The big story

These impossible instruments could change the future of music

October 2021

When Gadi Sassoon met Michele Ducceschi backstage at a rock concert in Milan in 2016, the idea of making music with mile-long trumpets blown by dragon fire, or guitars strummed by needle-thin alien fingers, wasn’t yet on his mind. 

At the time, Sassoon was simply blown away by the everyday sounds of the classical instruments that Ducceschi and his colleagues were re-creating with computers. 

The sounds were the early results of a curious project at the University of Edinburgh in Scotland, where Ducceschi was a researcher at the time. The project aimed to produce the most lifelike digital music ever created, by running simulations of trumpets, guitars, violins, and more on a supercomputer—creating a combination of sounds that would be pretty much impossible to nail otherwise.
