The Download: producing rare earth minerals, and future AI regulation

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.

The race to produce rare earth materials

Abandoning fossil fuels and adopting lower-carbon technologies are our best options for warding off the accelerating threat of climate change. And access to rare earth elements, key ingredients in many of these technologies, will partly determine which countries will meet their goals for lowering emissions.

Some nations, including the US, are increasingly worried about whether the supply of those elements will remain stable. As a result, scientists and companies alike are intent on increasing access and improving sustainability by exploring secondary or unconventional sources. Read the full story.

What's next for AI regulation in 2024?

In 2023, AI policy and regulation went from a niche, nerdy topic to front-page news. This is partly thanks to OpenAI's ChatGPT, which helped AI go mainstream, but which also exposed people to how AI systems work-and don't work.

It has been a monumental year for policy: we saw the first sweeping AI law agreed upon in the European Union, Senate hearings and executive orders in the US, and specific rules in China for things like recommender algorithms.

So if 2023 was the year lawmakers agreed on a vision, 2024 will be the year policies start to morph into concrete action. Here's what to expect.

These AI-powered apps can hear the cause of a cough

The news: Researchers have developed a smartphone app that can distinguish tuberculosis from other diseases by the sound of the patient's cough. Researchers trained and tested the diagnostic tool on recordings of coughs collected from 149 people with TB and 46 people with other respiratory conditions.

Why it matters: The method isn't foolproof. The app failed to detect TB in about 30% of people who actually had the disease. But it's simpler and vastly cheaper than collecting phlegm to look for the bacterium that causes the disease, the gold-standard method for diagnosing TB. So it could prove especially useful in low-income countries as a screening tool, helping to catch cases and interrupt transmission. Read the full story.

The big story

The quest to build wildfire-resistant homes

April 2023

With each devastating wildfire in the US West, officials consider new methods or regulations that might save homes or lives the next time.

In the parts of California where the hillsides meet human development, and where the state has suffered recurring seasonal fire tragedies, that search for new means of survival has especially high stakes.

Many of these methods are low cost and low tech, but no less truly innovative. In fact, the hardest part to tackle may not be materials engineering, but social change. Read the full story.
