Susan Collins announcing she'll vote against a controversial nominee is basically the moment it becomes clear that nominee will be confirmed. It means Thune has enough votes to confirm, and thus, Collins gets a pass to look independent.

This is the highest-resolution view of the surface of the Sun. Ever. Taken by the NSF's Daniel K. Inouye Solar Telescope, features as small as 19 km across can be resolved. The wispy things are magnetic field boundaries formed by Kelvin-Helmholtz instabilities. The island of Ireland for scale.

A swirling, complex view of yellow–orange–brown wisp-like features. The dark shape in the middle is a superposed outline of the island of Ireland to show scale.

Figure from that paper: red dots are samples reported in the paper, red line is modern oxygen levels. Samples are mostly below modern levels--and in the "you will die if you don't get supplemental oxygen" range. The past, it is weird and disquieting.

Plot from paper as described in the post. The x-axis is age in millions of years, from 600 million years ago to 200 million years ago (covering all of the Paleozoic, plus a bit of the Pre-Cambrian on the early side and the Triassic on the late side). The y-axis is pO2 in percent. Black lines mark prior proxy based estimates of oxygen levels in the atmosphere, red dots mark directly observed levels in air bubbles trapped in halite. The directly observed levels should be more accurate than the proxies, given how diagenesis works, and these show oxygen was below modern levels except for the middle Silurian.

Unusual asteroid unmasked! 🪨 Using our VLT in Chile & the Large Binocular Telescope in the US, astronomers have resolved the shape of (44) Nysa, a peculiar asteroid between Mars and Jupiter. They revealed a structure unlike anything observed before! 🔭 🧪 📹 ESO/K. Minker et al. 1/2

RFK Jr said these words today on national television "There were ICUs that were empty all over the country including in New York at the height (of the pandemic)" hahahahahahahahahahahahahahahahahahahahahahahahahahahahaha You are a fucking idiot hahahahahahahahahahahahahahahahaha <sobs silently>

Fatima Ameaka followed all the rules and she still got scooped on a domestic flight, caged, shipped to another cage, and then released with a promise of trial. The labyrinthine paperwork system is already cruel, now it's punctuated with random kidnappings.

Evidence so far suggests that it’s easier to discover previously unknown proofs in math and make new scientific discoveries than it is to make UI tests in Xcode pass reliably

The NASA administrator posted this to Twitter. Although I think there is a lot to comment on here, I think the most important point is that he provided a useful marker. 20% of the low-end Planetary Society estimate is ~$100 million. He has now said he will not pursue the mission if it costs >$100M.

I have started running Claude alongside the book I am writing on ants, as well as just letting Google Gemini do its thing at the top when I do Google search. It is not doing any writing I am using, and I am always checking the results against primary sources.
