The Download: brain bandwidth, and artificial wombs

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Elon Musk wants more bandwidth between people and machines. Do we need it?

Last week, Elon Musk made the bold assertion that sticking electrodes in people’s heads is going to lead to a huge increase in the rate of data transfer out of, and into, human brains.

The occasion of Musk’s post was the announcement by Neuralink, his brain-computer interface company, that it was officially seeking the first volunteer to receive an implant that contains more than twice the number of electrodes than previous versions to collect more data from more nerve cells.

The entrepreneur mentioned a long-term goal of vastly increasing “bandwidth” between people, or people and machines, by a factor of 1,000 or more. But what does he mean, and is it even possible? Read the full story.

Everything you need to know about artificial wombs

Earlier this month, US Food and Drug Administration advisors met to discuss how to move research on artificial wombs from animals into humans.

These medical devices are designed to give extremely premature infants a bit more time to develop in a womb-like environment before entering the outside world. They have been tested with hundreds of lambs (and some piglets), but animal models can’t fully predict how the technology will work for humans. 

Regulators are grappling with the question of how much of the unknown is acceptable as this research moves out of the lab and into first-in-human trials. But selecting the right participants will be tricky. Read the full story.

The big story

How big science failed to unlock the mysteries of the human brain

August 2021

In September 2011, Columbia University neurobiologist Rafael Yuste and Harvard geneticist George Church made a not-so-modest proposal: to map the activity of the entire human brain.

That knowledge could be harnessed to treat brain disorders like Alzheimer’s, autism, schizophrenia, depression, and traumatic brain injury, and help answer one of the great questions of science: How does the brain bring about consciousness? 

A decade on, the US project has wound down, and the EU project faces its deadline to build a digital brain. So have we begun to unwrap the secrets of the human brain? Or have we spent a decade and billions of dollars chasing a vision that remains as elusive as ever? Read the full story.
