What happens behind the scenes at the world’s many museums of natural history?
@jackdashby.bsky.social’s new book is an eye-opening first-hand account — and a good read

Breaking: The muon discrepancy seems to be officially gone. The Muon g–2 experiment at @fermilab.bsky.social
has just announced its final magnetic moment of the muon, improving precision by 1.8x. This is now in agreement with updated calculations published last week by the Theory Initiative ...🧵

In a 2009 @sciam.bsky.social article, Jack Szostak suggested that cycles of hot and cold might do the trick. Here is the figure showing the idea (for full disclosure: I had the fortune of working with Szostak as an editor). But there was a problem with stage 3 below [...]

Nickel production is notoriously dirty: ton per ton, it emits 10x more CO2 than steel — and that could get worse as demand increases. Now a proof-of-principle experiment described in @nature.com suggests a possible path to make green nickel using hydrogen plasma

... you get the same polynomial. For example, these are just different arrangements of the unknot, so they all just give the trivial Jones polynomial = 1.

The @esa.int Gaia spacecraft was moved out to a graveyard orbit and decommissioned today — but much of its discoveries are yet to come. Here is a 🧵 to recall milestones in the (still ongoing, but still with no Bluesky account?!) project

So, when @km3net.bsky.social detected the flashes from the nearly hoizontal track of a muon coming from Malta's direction, there was a good chance that it had originated in rock, not in water [3/4]

@km3net.bsky.social's ARCA array is anchored to the 3,500-deep seafloor southeast of Sicily. Malta, to the west of it, is in much shallower waters, as it sits on the continental shelf.

If are in Tokyo in the next two weeks, don’t miss the Super-Kamiokande exhibit at the awesome Miraikan that is due to be dismantled on Jan 13.
Takaaki Kajita won a Nobel Prize in 2020 for having led Super-K’s discovery that neutrinos oscillate between three different types.
