Google DeepMind trained a robot to beat humans at table tennis
What’s new: Google DeepMind has trained a robot to play table tennis at the equivalent of amateur-level competitive performance, the company has announced. It claims it’s the first time a robot has been taught to play a sport with humans at a human level.
How good is it? The system is far from perfect. Although the table tennis bot was able to beat all beginner-level human opponents it faced and 55% of those playing at amateur level, it lost all the games against advanced players. Still, it’s an impressive advance.
Why it matters: The research represents a step towards creating robots that can perform useful tasks skillfully and safely in real environments like homes and warehouses, which is a long-standing goal of the robotics community. Read the full story.

This futuristic space habitat is designed to self-assemble in orbit
More people are traveling to space, but the International Space Station can only hold 11 people at a time. The Aurelia Institute, a nonprofit space architecture lab based in Cambridge, MA, has an approach that may help: a habitat that can be launched in compact stacks of flat tiles and self-assemble in orbit.
Building large space habitats is difficult, and dangerous. But the Aurelia Institute’s TESSERAE space habitat, which resembles a futuristic, one-story-tall soccer ball, could make it much easier. Read the full story.

Watch a video showing what happens in our brains when we think
What does a thought look like? We can think about thoughts resulting from shared signals between some of the billions of neurons in our brains. Various chemicals are involved, but it really comes down to electrical activity. We can measure that activity and watch it back.
Ben Rapoport is the cofounder and chief science officer of Precision Neuroscience, a company doing just that. Rapoport and his colleagues have developed thin, flexible electrode arrays that can be slipped under the skull through a tiny incision. Once inside, they can sit on a person’s brain, collecting signals from neurons buzzing away beneath.
So far, 17 people have had these electrodes placed onto their brains. And Rapoport has been able to capture how their brains form thoughts. Check out his video of the brain thinking.

The big story
After 25 years of hype, embryonic stem cells are still waiting for their moment
In 1998, researchers isolated powerful stem cells from human embryos. It was a breakthrough for biology, since these cells are the starting point for human bodies and have the capacity to turn into any other type of cell—heart cells, neurons, you name it.
National Geographic would later summarize the incredible promise: “the dream is to launch a medical revolution in which ailing organs and tissues might be repaired” with living replacements. It was the dawn of a new era. A holy grail. Pick your favorite cliché—they all got airtime.
Yet today, more than two decades later, there are no treatments on the market based on these cells. Not one. Our biotech editor Antonio Regalado set out to investigate why, and when that might change. Here’s what he discovered.
We can still have nice things
