The Download: food from thin air, and finding new materials
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.
These companies are creating food out of thin air
A new crop of biotech startups, armed with carbon-guzzling bacteria and plenty of capital, are promising something that seems too good to be true. They say they can make food out of thin air.
But that's exactly how certain soil-dwelling bacteria work. In nature, they survive on a meager diet of oxygen, nitrogen, carbon dioxide, and water vapor drawn directly from the atmosphere.
In the lab, they do the same, eating up waste carbon and reproducing so enthusiastically that their populations swell to fill massive fermentation tanks. Siphoned off and dehydrated, that bacterial biomass becomes a protein-rich powder that's chock-full of nutrients and essentially infinitely renewable.
The ultimate goal of these companies is to engineer a food source far lower in emissions than conventional farming. But in order to do that, they'll need to overcome some very real challenges. Read the full story.

The race to find new materials with AI needs more data. Meta is giving massive amounts away for free.
What's new: Meta is releasing a massive data set and models, called Open Materials 2024, that could help scientists use AI to discover new materials much faster. OMat24 tackles one of the biggest bottlenecks in the discovery process: data.
Why it matters: To find new materials, scientists require massive data sets that are hard to come by. Creating them requires a lot of computing power and is very expensive. Many of the top data sets and models available now are also proprietary, and researchers don't have access to them. That's where Meta is hoping to help: The company is releasing its new data set and models today for free and is making them open source. Read the full story.

The big story
Inside the quest to map the universe with mysterious bursts of radio energy
When our universe was less than half as old as it is today, a burst of energy that could cook a sun's worth of popcorn shot out from somewhere amid a compact group of galaxies. Some 8 billion years later, radio waves from that burst reached Earth and were captured by a sophisticated low-frequency radio telescope in the Australian outback.
The signal, which arrived in June 2022, and lasted for under half a millisecond, is one of a growing class of mysterious radio signals called fast radio bursts. In the last 10 years, astronomers have picked up nearly 5,000 of them. This one was particularly special: nearly double the age of anything previously observed, and three and a half times more energetic.
No one knows what causes fast radio bursts. They flash in a seemingly random and unpredictable pattern from all over the sky. But despite the mystery, these radio waves are starting to prove extraordinarily useful. Read the full story.
