The race to fix space-weather forecasting before next big solar storm hits

As the number of satellites in space grows, and as we rely on them for increasing numbers of vital tasks on Earth, the need to better predict stormy space weather is becoming more and more urgent. 

Scientists have long known that solar activity can change the density of the upper atmosphere. But it’s incredibly difficult to precisely predict the sorts of density changes that a given amount of solar activity would produce. 

Now, experts are working on a model of the upper atmosphere to help scientists to improve their models of how solar activity affects the environment in low Earth orbit. If they succeed, they’ll be able to keep satellites safe even amid turbulent space weather, reducing the risk of potentially catastrophic orbital collisions. Read the full story.

How to reopen a nuclear power plant

A shut-down nuclear power plant in Michigan could get a second life thanks to a $1.52 billion loan from the US Department of Energy. If successful, it will be the first time a shuttered nuclear power plant reopens in the US.  

Palisades Power Plant shut down on May 20, 2022, after 50 years of generating low-carbon electricity. But the plant’s new owner thinks economic conditions have improved in the past few years and plans to reopen by the end of next year.

A successful restart would be a major milestone for the US nuclear fleet, and help inch the country closer to climate goals. But reopening isn’t as simple as flipping on a light switch. Here’s what it takes to reopen a nuclear power plant.

Threads is giving Taiwanese users a safe space to talk about politics

For months, Threads has been the most downloaded app in Taiwan, as users flock to the platform to talk about politics and more. On the platform itself, Taiwanese users are also belatedly realizing their influence when they see that comments under popular accounts, like a K-pop group, come mostly from fellow Taiwanese users.

But why did Threads succeed in Taiwan when it has failed in so many other places? Zeyi Yang, our China reporter, has dug into the surprising reasons why. Read the full story.

Quote of the day

“We’ve facilitated this common ground that people have. Not to be too heady about it, because it’s just sticks.”

—Boone Hogg, co-creator of the wildly popular Instagram account Official Stick Review, reflects on why such a simple concept has resonated with so many people to the New York Times.

The big story

How Meta and AI companies recruited striking actors to train AI

October 2023

Between July and September last year, actors in the US were invited to participate in an unusual research project, designed to capture their voices, faces, movements, and expressions.

The project, which coincided with Hollywood’s historic strikes, was run by London-based emotion AI company Realeyes and Meta. The information captured from the actors was fed into an AI database to better understand and express human emotions. 

Many actors across the industry worry that AI could be used to replace them, whether or not their exact faces are copied. And in this case, by providing the facial expressions that will teach AI to appear more human, study participants may in fact have been the ones inadvertently training their own potential replacements.
