People are using Google study software to make AI podcasts—and they’re weird and amazing
Google’s new AI podcasting tool, called Audio Overview, has become a surprise viral hit.
The podcasting feature was launched in mid-September as part of NotebookLM, a year-old AI-powered research assistant. NotebookLM, which is powered by Google’s Gemini 1.5 model, allows people to upload content such as links, videos, PDFs, and text. They can then ask the system questions about the content, and it offers short summaries.
The tool generates a podcast called Deep Dive, which features a male and a female voice discussing whatever you uploaded. The voices are breathtakingly realistic.
Yes, it’s cool—bordering on delightful, even—but it is also not immune from the problems that plague generative AI, such as hallucinations and bias. Here are some of the main ways people are using NotebookLM so far.

A new law in California protects consumers’ brain data. Some think it doesn’t go far enough.
On September 28, California became the second US state to officially recognize the importance of mental privacy in state law. Measuring brain activity can reveal a lot about a person—and that’s why neural data needs to be protected.Brain data is precious. It’s not the same as thought, but it can be used to work out how we’re thinking and feeling, and reveal our innermost preferences and desires. Jessica Hamzelou, our senior biotech reporter, has taken a look at how California’s law might protect mental privacy—and how far we still have to go. Read the full story.

The big story
The humble oyster could hold the key to restoring coastal waters. Developers hate it.
October 2023
Carol Friend has taken on a difficult job. She is one of the 10 people in Delaware currently trying to make it as a cultivated oyster farmer.
Her Salty Witch Oyster Company holds a lease to grow the mollusks as part of the state’s new program for aquaculture, launched in 2017. It has sputtered despite its obvious promise.
Five years after the first farmed oysters went into the Inland Bays, the aquaculture industry remains in a larval stage. Oysters themselves are almost mythical in their ability to clean and filter water. But human willpower, investment, and flexibility are all required to allow the oysters to simply do their thing—particularly when developers start to object. Read the full story.
