The Download: a novel form of censorship in China, and a self-taught robot dog

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.

A million-word novel got censored before it was even shared. Now Chinese users want answers.

Imagine you are working on your novel on your home computer. It's nearly finished; you have already written approximately one million words. All of a sudden, the online word processing software tells you that you can no longer open the draft because it contains illegal information. Within an instant, all your words are lost.

This is what happened in June to a Chinese novelist writing under the alias Mitu. She had been working with WPS, a domestic version of cloud-based word processing software such as Google Docs or Microsoft Office 365. In the Chinese literature forum Lkong on June 25, Mitu accused WPS of spying on and locking my draft," citing the presence of illegal content. Several other novelists say they have had their drafts locked for unclear reasons in the past.

Mitu's complaint triggered a social media discussion in China about censorship and tech platform responsibility. It has also highlighted the tension between Chinese users' increasing awareness of privacy and tech companies' obligation to censor on behalf of the government. Read the full story.

This robot dog just taught itself to walk

The robot dog is waving its legs in the air like an exasperated beetle. After 10 minutes of struggling, it manages to roll over to its front. Half an hour in, the robot is taking its first clumsy steps, like a newborn calf. But after one hour, the robot is strutting around the lab with confidence.

What makes this four-legged robot special is that it learned to do all this by itself, without being shown what to do in a computer simulation.

Researchers used an AI technique called reinforcement learning, which trains algorithms by rewarding them for desired actions, to train the robot to walk from scratch in the real world.

Traditionally, robots are trained in a computer simulator first, but these findings suggest reinforcement learning-based techniques could teach robots new skills in real-world environments in a relatively short amount of time. Read the full story.

Meet Altos Labs, Silicon Valley's latest wild bet on living forever

September 2021

An ambitious new anti-aging company has burst onto the scene: Altos Labs. It's backed by billionaire investors like Jeff Bezos and Yuri Milner, and has recruited a large cadre of top scientists with lavish salaries. It will establish several institutes in places including the Bay Area, San Diego, Cambridge, UK and Japan.

Altos is pursuing biological reprogramming technology, a way to rejuvenate cells in the lab that some scientists think could be extended to revitalize entire animal bodies, ultimately prolonging human life. It's a nascent field, risky, and a long way from human therapy-but it has huge promise. Read the full story.
