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

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 false rumor of a Chinese coup went viral

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.

First of all, let’s be very clear: this report is false and should not be taken seriously. No credible sources on China have bought it. It’s wishful thinking at best, and intentional disinformation at worst.

But it’s interesting to dissect how a ridiculous rumor could be elevated and spread so widely that it made it to Twitter’s deeply flawed trending list over the weekend, thanks to influencer translation and amplification from accounts based in India. Read the full story.

How robots and AI are helping develop better batteries

The news: At the start of this year, Carnegie Mellon researchers used a robotic system to run dozens of experiments designed to generate electrolytes to charge lithium-ion batteries faster, addressing one of the major obstacles to the widespread adoption of electric vehicles.

How they did it: A system of automated pumps, valves, and instruments mixed various solvents, salts, and other chemicals together, then measured how the solution performed on critical battery benchmarks. Those results were then fed into a machine-learning system, known as Dragonfly, that used the data to propose different combinations that might work even better.

Why it matters: Developing better electrolytes is crucial for improving the performance, safety, and cost of batteries. Faster-charging batteries are especially important for making electric cars and trucks more appealing. Read the full story.

The big story

The hunt for hidden signs of consciousness in unreachable patients

August 2021

At first glance, there’s nothing remarkable about the low-rise hospital on the west side of Milan. But two floors up, on an isolated wing of the Don Carlo Gnocchi IRCCS Centro S. Maria Nascente, an uncommunicative man with a severe brain injury is hooked up to a technology suite that researchers here believe can tell them if he’s conscious.

A neuroscientist and the patient’s neurologist watch on a laptop as complicated blue squiggles representing brain waves fill the screen in close to real time. What the scientists see in them is the faintest sign of a liminal, maybe dreamlike, consciousness.

Such a breakthrough represents the most accurate consciousness meter ever seen in medicine (even if it is still crude, rudimentary, and unrefined)—with wide reaching medical implications. Read the full story.
