The Download: the future of music AI, and climate tech funding

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.

Training AI music models is about to get very expensive

AI music is suddenly in a make-or-break moment. On June 24, Suno and Udio, two startups that let you generate complete songs from a prompt in seconds, were sued by major record labels. The labels alleged the startups had used copyrighted music as training data at an almost unimaginable scale".

Just two days later, the Financial Times reported that YouTube is pursuing a comparatively above-board approach. Rather than training AI music models on secret data sets, the company is reportedly offering unspecified lump sums to top record labels in exchange for licenses to use their catalogs for training data.

While the ground here is moving fast, none of these moves should be all that surprising: litigious training-data battles have become something like a rite of passage for generative AI companies. The trend has led many to pay for licensing deals while the cases unfold.

But the stakes of a fight over training data for AI music are different-and arguably even higher. Read our story to find out why, and what might happen next.

These climate tech companies just got $60 million

Every few years, the US agency that's often called the energy moonshot factory" announces big funding awards for a few companies to help them scale up their technology. (The agency's official name is the Advanced Research Projects Agency-Energy, or ARPA-E.)

The grants are designed to help companies take their tech from the lab or pilot stage and get it out into the world. The latest batch of these awards was just announced, totaling over $63 million split between four companies. Read our story that digs into the winners and examines what each one's technology says about their respective corners of climate action.

Lego bricks are making science more accessible

Etienne Boulter walked into his lab at the Universite Cote d'Azur in Nice, France, one morning with a Lego Technic excavator set tucked under his arm. His plan was simple yet ambitious: to use the pieces of the set to build a mechanical cell stretcher.

Boulter and his colleagues study mechanobiology-the way things like stretching or compression affect cells-and this piece of equipment is essential for his research. Commercial cell stretchers cost over $50,000. But one day, after playing with the Lego set, Boulter and his colleagues found a way to build one out of its components for only a little over $200.

Their Lego system stretches a silicone plate where cells are growing. This process causes the cells to deform and mimics how our own skin cells stretch. And Boulter is not alone. In fact, he's one of many researchers turning to Lego components to build inexpensive yet extremely effective lab equipment. Read the full story.

Quote of the day

There's no question that this crosses a line that they hadn't previously crossed. I think that suggests that the lines are becoming meaningless."

-Darren Linvill, a founder of the Media Forensics Hub at Clemson University, tells the New York Times that aggressively targeting a US-based Chinese dissident's 16-year-old daughter online represents a new low for the country's security services.

The big story

Think that your plastic is being recycled? Think again.

MICHAEL BYERS

October 2023

The problem of plastic waste hides in plain sight, a ubiquitous part of our lives we rarely question. But a closer examination of the situation is shocking.

To date, humans have created around 11 billion metric tons of plastic, the vast majority of which ends up in landfills or the environment. Only 9% of the plastic ever produced has been recycled.

To make matters worse, plastic production is growing dramatically; in fact, half of all plastics in existence have been produced in just the last two decades.

So what do we do? Sadly, solutions such as recycling and reuse aren't equal to the scale of the task. The only answer is drastic cuts in production in the first place. Read the full story.
