Summary
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.

| 0:00.0 | Hello, recording this introduction from our origins travel experience in the amazing country of Bhutan. |
| 0:18.4 | Last week, before I left, I got to have a wonderful discussion once again for our most recent |
| 0:26.0 | What's New in Science episode with Sabina Hossenfeldar. |
| 0:30.2 | We covered a lot of interesting topics, ranging from the recent claims of the dark energy |
| 0:36.9 | survey spectroscopic instrument, |
| 0:39.2 | that potentially dark energy, the energy of empty space, is changing. |
| 0:45.6 | I don't think it probably is. |
| 0:47.1 | I think it's likely to be shown not to be. |
| 0:49.8 | To another space observatory, the Euclid Space Observatory, |
| 0:53.4 | looking at gravitational |
| 0:54.5 | lensing from many galaxies after surveys of 26 million galaxies finding an initial result of almost |
| 1:05.1 | 500 strong lensing candidates, which is just amazing. We went back to talking about quantum computing again and a new |
| 1:13.0 | chip that may be much more interesting than the one we talked about last time. This is an Amazon |
| 1:16.9 | quantum chip, which embeds error correction, which is probably the most important aspect of trying |
| 1:25.6 | to make quantum computers work. And we talked about that |
| 1:30.3 | to what seemed like a perpetual motion machine, an interesting result that just appeared in a |
| 1:34.7 | physics journal of the possibility of using the Earth's magnetic field to somehow generate |
| 1:40.7 | electro currents in a material. |
| 1:45.0 | It almost sounds like it should be impossible, |
| 1:47.8 | but I actually think it isn't. |
| 1:49.1 | It's not as if it's a practical device |
| 1:50.7 | that's going to produce energy for humanity, |
