The Download: China’s covid pop-up, and resolving Twitter’s ownership row
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.
How the covid pop-up window is wreaking havoc on daily life in China
In 2020, China rolled out a contact tracing program that assigns a QR code to everyone in the country. It shows your covid status and allows you to enter public venues or take public transportation. Part of China’s stringent zero-covid policy, the system has persisted, and some of the once-lauded features that kept deaths comparatively low in the country now feel more burdensome than beneficial to its citizens.
For example, the more than 20 million people who live in or visit Beijing are now being plagued by a pop-up window that can randomly show up on your phone to disrupt all your plans. The persistent pop-up is designed to mask the QR code, preventing access to just about everywhere in China, and won’t go away unless the user immediately takes a PCR test.
The problem is, despite being touted as a high-tech pandemic solution, the app’s risk-identifying mechanism tends to cast a wider-than-necessary net, meaning no one knows why they are receiving the pop-up window or when they will get it, and there’s no way to prepare for it. Read the full story.

Podcast: I Was There When AI Mastered Chess
In the late 90s, IBM’s Deep Blue computer beat Garry Kasparov—the reigning world champion of chess. It paved the way for a revolution in automation. In the latest episode of MIT Technology Review’s In Machines We Trust podcast, we meet Kasparov and hear the battle with Deep Blue told from his side of the chessboard. Listen to it on Apple Podcasts, or wherever else you usually listen.

The big story
The Atlantic’s vital currents could collapse. Scientists are racing to understand the dangers.
December 2021
Scientists and technicians are searching for clues about one of the most important forces in the planet’s climate system: a network of ocean currents known as the Atlantic Meridional Overturning Circulation (AMOC). Critically, they want to better understand how global warming is changing it, and how much more it could shift in the coming decades—even whether it could collapse.
The problem is the Atlantic circulation seems to be weakening, transporting less water and heat. Because of climate change, melting ice sheets are pouring fresh water into the ocean at the higher latitudes, and the surface waters are retaining more of their heat. Warmer and fresher waters are less dense and thus not as prone to sink, which may be undermining one of the currents’ core driving forces. Read the full story.
