Anthropic can now track the bizarre inner workings of a large language model
The news: The AI firm Anthropic has developed a way to peer inside a large language model and watch what it does as it comes up with a response, revealing key new insights into how the technology works. The takeaway: LLMs are even stranger than we thought.
Why it matters: It’s no secret that large language models work in mysterious ways. Shedding some light on how they work would expose their weaknesses, revealing why they make stuff up and can be tricked into going off the rails. It would help resolve deep disputes about exactly what these models can and can’t do. And it would show how trustworthy (or not) they really are. Read the full story.

What is Signal? The messaging app, explained.
With the recent news that the Atlantic’s editor in chief was accidentally added to a group Signal chat for American leaders planning a bombing in Yemen, many people are wondering: What is Signal? Is it secure? If government officials aren’t supposed to use it for military planning, does that mean I shouldn’t use it either?
The answer is: Yes, you should use Signal, but government officials having top-secret conversations shouldn’t use Signal. Read the full story to find out why.

“Spare” living human bodies might provide us with organs for transplantation
—Jessica Hamzelou
This week, MIT Technology Review published a piece on bodyoids—living bodies that cannot think or feel pain. In the piece, a trio of scientists argue that advances in biotechnology will soon allow us to create “spare” human bodies that could be used for research, or to provide organs for donation.
If you find your skin crawling at this point, you’re not the only one. It’s a creepy idea, straight from the more horrible corners of science fiction. But bodyoids could be used for good. And if they are truly unaware and unable to think, the use of bodyoids wouldn’t cross “most people’s ethical lines,” the authors argue.
I’m not so sure. Read the full story.

The big story
The race to fix space-weather forecasting before next big solar storm hits
April 2024
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.
