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.

The big new idea for making self-driving cars that can go anywhere

Four years ago, Alex Kendall sat in a car on a small road in the British countryside and took his hands off the wheel. The car was equipped with a few inexpensive cameras and a large neural network. It veered towards the edge. Kendall grabbed the steering wheel and corrected it when it did. Kendall was able to correct the car’s veering again. It took less than 20 minutes for the car to learn to stay on the road by itself, he says.

This was the first time that reinforcement learning–an AI technique that trains a neural network to perform a task via trial and error–had been used to teach a car to drive from scratch on a real road. This was a small step forward in a new direction that startups believe could lead to driverless cars becoming a common reality.

These startups, who call themselves AV2.0, believe that cheaper, smarter tech will allow them to overtake market leaders. Indeed, Kendall’s firm Wayve says it wants to be the first company to deploy driverless cars in 100 different cities.

But is this yet more hype from an industry that’s been drinking its own Kool-Aid for years? Read more .

Watch a robotic shoulder practice twisting and stretching human cells

A robotic shoulder that stretches, presses, and twists lab-grown human tendon tissue could pave the way for more successful tissue grafts.

Although tissue engineering is still a relatively new field, patients have had skin, cartilage, and even windpipes implanted from human cells. It has been more difficult to grow usable human tendon cells, which need to stretch and twist.

For the past 20 years, scientists have encouraged engineers to encourage tendon cells and tissues to grow and mature by repeatedly stretching them one way. This approach has not been able to produce functional tissue grafts that can be used in humans.

Humanoid robots may be used to create engineered tendon tissue more like the real thing. Read the complete story — and watch the robot in action.

The big story

Why you don’t really know what you know
October 2020

What does it really mean to know anything? How can we really understand the world when so much depends on arguments and evidence from others?

These questions matter not only to scientists. These questions are important in many other fields, as we have more information and better opinions than ever before. However, misinformation and political polarization are making it difficult to know who or what to trust. Read the full story.
