The Download: head transplants, and filtering sounds with AI

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.

That viral video showing a head transplant is a fake. But it might be real someday.

An animated video posted this week has a voice-over that sounds like a late-night TV ad, but the pitch is straight out of the far future. The arms of an octopus-like robotic surgeon swirl, swiftly removing the head of a dying man and placing it onto a young, healthy body.

This is BrainBridge, the animated video claims-the world's first revolutionary concept for a head transplant machine, which uses state-of-the-art robotics and artificial intelligence to conduct complete head and face transplantation."

BrainBridge is not a real company-it's not incorporated anywhere. Yet it's not merely a provocative work of art. This video is better understood as the first public billboard for a hugely controversial scheme to defeat death that's recently been gaining attention among some life-extension proponents and entrepreneurs.

Noise-canceling headphones use AI to let a single voice through

Modern life is noisy. If you don't like it, noise-canceling headphones can reduce the sounds in your environment. But they muffle sounds indiscriminately, so you can easily end up missing something you actually want to hear.

A new prototype AI system for such headphones aims to solve this. Called Target Speech Hearing, the system gives users the ability to select a person whose voice will remain audible even when all other sounds are canceled out.

Although the technology is currently a proof of concept, its creators say they are in talks to embed it in popular brands of noise-canceling earbuds and are also working to make it available for hearing aids. Read the full story.

Splashy breakthroughs are exciting, but people with spinal cord injuries need more

-Cassandra Willyard

This week, I wrote about an external stimulator that delivers electrical pulses to the spine to help improve hand and arm function in people who are paralyzed. This isn't a cure. In many cases the gains were relatively modest.

The study didn't garner as much media attention as previous, much smaller studies that focused on helping people with paralysis walk. Tech that allows people to type slightly faster or put their hair in a ponytail unaided just doesn't have the same allure.

For the people who have spinal cord injuries, however, incremental gains can have a huge impact on quality of life. So who does this tech really serve? Read the full story.

The big story

How Facebook got addicted to spreading misinformation

March 2021

When the Cambridge Analytica scandal broke in March 2018, it would kick off Facebook's largest publicity crisis to date. It compounded fears that the algorithms that determine what people see were amplifying fake news and hate speech, and prompted the company to start a team with a directive that was a little vague: to examine the societal impact of the company's algorithms.

Joaquin Quinonero Candela was a natural pick to head it up. In his six years at Facebook, he'd created some of the first algorithms for targeting users with content precisely tailored to their interests, and then he'd diffused those algorithms across the company. Now his mandate would be to make them less harmful. However, his hands were tied, and the drive to make money came first. Read the full story.
