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, equipped with a few cheap cameras and a massive neural network, veered towards the verge. When it did, Kendall grabbed the wheel for a few seconds to correct it. The car veered again; Kendall corrected it. 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. It was a small step in a new direction—one that a new generation of startups believe just might be the breakthrough that makes driverless cars an everyday reality.
Branding themselves AV2.0, these startups are betting that smarter, cheaper tech will let them overtake current 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 the full story.

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.
Though the field of tissue engineering is still mostly experimental, skin cells, cartilage, and even a windpipe grown from samples of human cells have been implanted in patients. But growing usable human tendon cells—which need to stretch and twist—has proved trickier.
Over the past two decades, scientists have encouraged engineered tendon cells and tissue to grow and mature by repeatedly stretching them in one direction. However, this approach has so far failed to produce fully functional tissue grafts that could be used in human bodies.
Humanoid robots could be used to make engineered tendon tissue that is more like the real thing. Read the full story—and watch the robot in action.

The big story
Why you don’t really know what you know
What does it really mean to know anything? How well can we understand the world when so much of our knowledge relies on evidence and argument provided by others?
These questions matter not only to scientists. Many other fields are becoming more complex, and we have access to far more information and informed opinions than ever before. Yet at the same time, increasing political polarization and misinformation are making it hard to know whom or what to trust. Read the full story.
