The porcelain challenge didn’t need to be real to get views
Despite what you may have heard, teens are not stealing their family’s fine dinnerware, tossing it in a blender, and snorting the resulting dust for the “porcelain challenge.”
That’s just what Sebastian Durfee, a 23-year-old actor and TikTok creator, hoped you might believe when he spread the word on social media of 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 get “boomers to 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 examine how attention and outrage work online, and, in a new twist, to trick the very people who were in on the joke in the first place. Read the full story.

DeepMind’s game-playing AI has beaten a 50-year-old record in computer science
What’s happened: DeepMind has used its board game-playing AI AlphaZero to discover a faster way to solve a fundamental math problem in computer science, beating a record that has stood for more than 50 years.
Why it matters: The problem, matrix multiplication, is a crucial type of calculation at the heart of 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 could have a big impact on thousands of everyday computer tasks, cutting costs and saving energy. Read the full story.

Inside a battery recycling facility
A massive new battery recycling facility from Redwood Materials is being built in the mountains just outside Reno, Nevada. My colleague Casey Crownhart, our climate reporter, took a look around to see how the construction’s going, including on the hydrometallurgical building, where valuable metals—lithium, nickel, cobalt, and copper—will be isolated from crushed battery materials.

The big story
Gene editing has made pigs immune to a deadly epidemic
December 2020
When covid-19 began to spread, countries closed businesses and told people to stay 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 contracting diseases, pig farmers employ measures familiar to anyone who has been avoiding covid-19, including requiring human workers to change clothes before entering a secure barn, answering questions about their last pig contact and dousing supplies in disinfectant.
Now the Pig Improvement Company, in Hendersonville, Tennessee, is trying something different. Instead of trying to seal animals off from the environment, it’s changing the pigs themselves. At a secret experimental facility in the US, the company has a swine IVF center and a lab where pig eggs are being genetically edited using CRISPR, the revolutionary gene scissors, to make piglets immune to deadly diseases.
