Brazilians are turning to Instagram to identify far-right rioters

In the hours after far-right insurrectionists trashed government buildings in Brazil’s capital on Sunday January 8, a new account popped up on Instagram. 

Called Contragolpe Brasil, it quickly started posting photos of alleged riot participants, reaching more than 1 million followers in just 24 hours. The idea was to crowdsource information that could identify “people who attack democracy in Brazil,” making it easier for authorities to find and punish those who escaped arrest on the day.

Not long after the account started posting, comments started to roll in, including people’s full names, the cities and states where they live, and their Instagram handles. But trying to identify criminals online can be risky, especially if people get it wrong. Read the full story.

NASA’s return to the moon is off to a rocky start

Five decades after man first set foot on the moon, NASA has a plan to send astronauts back. The Artemis project aims to visit a new area of the moon and retrieve samples, this time with new faces behind the sun visors—including the first woman and first person of color. 

Whether this plan will succeed—and whether a fresh moon landing will inspire a new “Artemis generation” in space exploration—is a matter of debate. 

Although its first mission thundered into space in November, if something goes wrong, or if the powerful Space Launch System rocket that carried it is deemed too expensive or unsustainable, there’s a chance the entire moon program will fail—or at least be similarly judged. Read the full story.

TR10: Ancient DNA analysis

Scientists have long sought better tools to study teeth and bones from ancient humans. In the past, they’ve had to sift through countless ancient remains to find a sample preserved well enough to analyze.  

Now cheaper techniques and new methods that make damaged DNA legible to commercial sequencers are powering a boom in ancient DNA analysis—and uncovering extinct species along the way.

Ancient DNA analysis is just one of our 10 Breakthrough Technologies, which we’re showcasing one-by-one in The Download each day. You can check out the rest of the list for yourself, and vote in our poll to help us decide what should make our final 11th technology.

The big story

China’s path to modernization has, for centuries, gone through my hometown

June 2021

For generations, politicians and intellectuals have sought ways to build a strong China. Some imported tools and ideas from the West. Others left for a better education, but the homeland still beckoned.

Yangyang Cheng, a particle physicist at Yale Law School, is a product of their complex legacy. She grew up in Hefei, then a humble, medium-sized city in central-eastern China, which is now a budding metropolis with new research centers, manufacturing plants, and technology startups. For two of the city’s proudest sons, born a century apart, a strong homeland armed with science and technology was the aspiration of a lifetime. Cheng grew up with their stories. They teach her about the forces that propelled China’s rise, and the way lives can be squeezed by the pressures of geopolitics. Read the full story.
