Elon Musk’s Neuralink hopes to test its brain implant in a human next year

Elon Musk’s brain-computer interface company Neuralink is planning to test a brain implant in humans in six months, the company has announced.

At a ‘show and tell’ event yesterday, Musk said that the company was in the process of submitting paperwork to the US Food and Drug Administration, which has the power to approve or deny the company’s application to start clinical trials in humans.

When Musk launched Neuralink in 2017, he outlined plans for “a high-bandwidth, long-lasting, biocompatible, bidirectional” brain implant. This brain modem, he claimed, could somehow allow humans to keep pace with artificial intelligence. Now, after years of delays and experiments on monkeys, he’s hoping to prove it can be safely implanted in humans.

Musk also announced that the company is working on repurposing the implant for two further parts of the body: the spinal cord, to potentially help to restore movement in someone who is paralysed, and an ocular implant to restore vision in people with sight loss. He demonstrated the latter product with a video explaining how a Neuralink implant had stimulated a flash of light in a monkey’s brain.

Antonio Regalado, our senior biomedicine editor, correctly predicted that a vision implant capable of generating images in an animal’s brain would make its way into the company’s presentation. Read why that matters—and what, in theory, it could mean for humans.

While everyone waits for GPT-4, OpenAI is still fixing its predecessor

Buzz around GPT-4, the anticipated but as-yet-unannounced follow-up to OpenAI’s groundbreaking large language model, GPT-3, is growing by the week. But OpenAI is not yet done tinkering with the previous version.

The San Francisco-based company has released a demo of a new model called ChatGPT, a spin-off of GPT-3 that is geared toward answering questions via back-and-forth dialogue. But while the conversational format allows ChatGPT to admit its mistakes, and reject inappropriate requests, it’s still far from perfect. Read the full story.

In defense of plastic (sort of)

Plastics have a bad reputation, there’s no denying it. They’re an environmental, climate, and public health disaster. But, simultaneously, they’ve brought down costs across industries and saved lives, thanks to their use in everything from medical equipment to electronics.

The question is, where do we go from here? Taking steps to cut down on gratuitous plastic use is a start, and finding ways to reinvent plastic recycling could also play a huge role in cutting down on its negative impacts. Among the most promising of these is chemical recycling, which, if chemists successfully pull it off, could allow us to handle different plastics using a single process. Read the full story.
