What's New in Science With Sabine and Lawrence

I’m excited to announce the third episode of our new series, What’s New in Science, co-hosted by Sabine Hossenfelder. Once again, Sabine and I each brought a few recent science stories to the table, and we took turns introducing them before diving into thoughtful discussions. It’s a format that continues to spark engaging exchanges, and based on the feedback we’ve received, it’s resonating well with listeners.This time, we covered a wide range of intriguing topics. We began with the latest buzz from the Dark Energy Spectroscopic Instrument suggesting that dark energy might be changing over time. I remain skeptical, but the possibility alone is worth a closer look. We followed that with results from the Euclid space telescope, which has already identified nearly 500 strong gravitational lensing candidates—an impressive yield from just the early data.We also returned to quantum computing, comparing the hype around Microsoft’s recent claims to Amazon’s quieter but arguably more meaningful development—a chip with built-in error correction, which could mark real progress toward scalable systems. From there we went to Earth, where a team at Princeton reported a result that almost sounds like a perpetual motion machine: using the Earth’s magnetic field to generate electric current. It’s not going to power the grid, but it raises fascinating questions.And of course, we couldn’t resist discussing a new round of exotic claims about hidden structures beneath the Pyramids of Giza, before wrapping up with a reanalysis of decade-old data from the Curiosity rover on Mars. It suggests the presence of organic compounds that might hint at life—but as always, the story is more complicated.It was another lively and thoughtful exchange, and I hope you’ll enjoy it as much as we did.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.
