A few highlights from lecture yesterday at Nordita, about numerical techniques to evolve magnetic fields in cosmological simulations and (try to) simulate small-scale dynamo amplification.
Message 1. there is no best method for all needs: it depends
Message 2: they all are anyway wrong as they probe a different regime of plasma than is in nature - the best we can do is to hope we can extrapolate results to the right regime.

Now there are two areas where it seems that increased #retraction rates are likely not due to increased scrutiny of published articles, but, rather, due to lower quality publications. I would still not bet that these data will help sway any of the “increased scrutiny” proponents.

We don't need more didactic videos or step-by-step manuals about the Fediverse.
Those already exist in abundance. Beyond that, we have something much more powerful: people who are genuinely willing to welcome newcomers, answer questions, and help others find their footing.
What we need is more people creating content that inspires others to stay. Most newcomers aren’t leaving because they don’t understand the concept of the Fediverse. They leave because their timeline seems empty, boring, or irrelevant compared to other platforms that aggressively serve them content.
The real challenge isn't education, but attraction and discovery. If the Fediverse is full of interesting conversations, art, humor, politics, niche expertise, and human warmth, people will accept that building a timeline takes time. But only if there's something worth building toward.
Comets are cold, but they're full of silicate crystals that form at high temperatures. (These crystals, left, were collected from Comet Wild 2, right.)
Now we know how that happens! Newborn stars blow fast, crystalline winds away from their hot inner regions.

Crystal winds blow through the picturesque gas clouds where stars are forming.
JWST caught the process in action: A protostar called EC53 had an outburst & crystals of forsterite and enstatite formed before our eyes. The future of our galaxy is taking shape here.

🐋🌊 New #research into #Alaska's #BristolBay beluga whales reveals a surprising social strategy. Instead of a few dominant males, these long-lived #whales take a "plenty of #fish in the sea" approach, frequently switching partners to maintain genetic #health.
This flexible mating system helps their small, isolated population avoid inbreeding.
