As AI models become better at mimicking human behavior, it’s becoming increasingly difficult to distinguish between real human internet users and sophisticated systems imitating them.
That’s a real problem when those systems are deployed for nefarious ends like spreading misinformation or conducting fraud, and it makes it a lot harder to trust what you encounter online.
A group of researchers have developed a potential solution— a verification concept called ‘personhood credentials’ that proves its holder is a real person, without revealing any further information about their identity. Read the full story to learn how it works.

The race to replace the powerful greenhouse gas that underpins the power grid
The power grid is underpinned by a single gas that is used to insulate a range of high-voltage equipment. The problem is, it’s also a super powerful greenhouse gas: a nightmare for climate change.
Sulfur hexafluoride (or SF6) is far from the most common gas that warms the planet, contributing around 1% of warming to date—carbon dioxide and methane are much more well-known and abundant. But emissions of the gas are steadily ticking up every year.
Now, companies are looking to do away with equipment that relies on the gas and searching for replacements that can match its performance. Read the full story.

10 Why AI is such a compelling movie villain
From 2001: A Space Odyssey to the Terminator to the Matrix. (WP $)
Abandoning fossil fuels and adopting lower-carbon technologies are our best options for warding off the accelerating threat of climate change. And access to rare earth elements, key ingredients in many of these technologies, will partly determine which countries will meet their goals for lowering emissions.
Some nations, including the US, are increasingly worried about whether the supply of those elements will remain stable. As a result, scientists and companies alike are intent on increasing access and improving sustainability by exploring secondary or unconventional sources. Read the full story.
