The Download: China's non-coup, and building better batteries

If you're on Twitter and follow news about China, you likely have heard a pretty wild rumor recently: that President Xi Jinping was under house arrest and that there was about to be a major power grab in the country.

This story is from China Report, MIT Technology Review's new newsletter giving you the inside scoop on what's happening in China.
