The porcelain challenge didn’t have to be real to get views
Despite what you may have heard, teenagers don’t steal their family’s fine tableware, throw it in a blender and sniff the resulting dust for the “porcelain challenge.”
That’s exactly what Sebastian Durfee, a 23-year-old actor and creator of TikTok, hoped you’d believe when he spread the word on social media about the latest dangerous teen challenge. Never mind that it was all fake from the start.
Last week, Durfee posted a call to action to his followers: to work together to “make boomers freak out about a fake TikTok challenge”. His account was banned just a few days later, but his goal wasn’t just to rack up views. It was also to explore how attention and outrage works online, and, in a new twist, to mislead the people who were into the joke in the first place. Read the full story.

DeepMind’s game-playing AI has broken a 50-year-old record in computer science
What happened: DeepMind has used its board game AI AlphaZero to discover a faster way to solve a fundamental math problem in computer science, a record that has stood for more than 50 years.
Why it matters: The problem, matrix multiplication, is a crucial type of computation that is central to many different applications, from displaying images on a screen to simulating complex physics. It is also fundamental to machine learning itself. Speeding up this calculation can have a major impact on thousands of daily computing tasks, cutting costs and saving energy. Read the full story.

In a battery recycling facility
A massive new battery recycling facility from Redwood Materials is being built in the mountains just outside of Reno, Nevada. My colleague Casey Crownhart, our climate reporter, looked around to see how construction is progressing, including in the hydrometallurgical building, where valuable metals — lithium, nickel, cobalt and copper — will be isolated from fractured battery materials.

The big story
Gene editing has made pigs immune to a deadly epidemic

Dec 2020
As Covid-19 started to spread, countries closed businesses and told people to stay at home. Many thought that would be enough to stop the coronavirus. If we had paid more attention to pigs, we might have known better.
To prevent their animals from contracting disease, pig farmers are applying measures known to anyone who has avoided covid-19, including requiring human workers to change clothes before entering a secure barn, answering questions about their last contact with the pig and pouring over stocks of disinfectant.
Now the Pig Improvement Company, in Hendersonville, Tennessee, is trying something different. Instead of trying to cut off animals from the environment, it changes the pigs themselves. In a secret experimental facility in the US, the company has a pig IVF center and a lab where pig eggs are genetically edited with CRISPR, the revolutionary gene scissors, to make piglets immune to deadly diseases.
