A Nature Astronomy paper shows that Earth lies within a narrow “Goldilocks zone” that allows both nitrogen and phosphorus to be present with the right abundances in the mantle. More oxidized or reduced exoplanets may lock these elements in their cores, limiting habitability. 🔭 🧪

The chemical habitability of Earth and rocky planets prescribed by core formation - Nature Astronomy
A narrow ‘Goldilocks zone’ of oxidation levels during exoplanetary core formation allows both nitrogen and phosphorus to remain in the mantle. Earth lies within this zone, but more oxidized or reduced exoplanets may lock these elements in their cores, limiting habitability.

BBC's Arabic radio service in Lebanon closed after 85 years as part of a £28.5m savings drive. 'Just months later, in October 2023, the Russian state-owned Sputnik news agency took over the frequency. Its news bulletin opened with “This is Moscow”, replacing the previous “This is London” intro.' 🙄

Labour seems wedded to a model of immigration based on creating a subclass of exploited worker.

‪I roll my eyes at most people talking about the measurement problem in quantum mechanics, but Wojciech Zurek is the real deal.

He's been working on it for decades, making steady progress. This is a good quick intro to where he's at now. Of course it's no substitute for reading Zurek's papers!
Resolving the "measurement problem" in quantum mechanics would be a huge deal. Doing it without any exotic assumptions or additions to standard QM would be amazing. Now, I'm not reckless enough to say that is what has been achieved here, but...
