Life is probably older than that. Carbon consistent with organ fractionation shows up as inclusions in Jack Hills Zircons. Life is very likely older than any extant rock.

Forgot to mention it earlier, but if anyone's in the Belchertown area, free concert on the common tonight at 7, Belchertown Community Band. I'll be the one behind the euphonium

Yeah it should be an emergency situation for literally everyone that we’re casually introducing more methods of torture into the carceral state while the President & every one of his fiefdom controlling feudal lords want to arrest people for simply not agreeing with them.
Just 6 years ago there was a broad consensus on ending cash bail and not treating anyone taken by the police as convicted prisoners serving sentences from a judge. But something something woke DEI and now we’re seeing people argue people in jail should be tortured with shock gloves.
I'm a big fan of Upright Health (many of his mobility exercises have been EXCELLENT for me), but I feel like this video (with the accurate yet clickbait-y title) is something a lot of people might benefit from seeing.

Lorenzo Quilici, the greatest topographer of ancient Italy of several generations, has gone to document the great road in the sky
Lovely to get coffee and catch up with one of my high school history teachers (long since retired) this morning
Cool medical news that hopefully will proceed to a human study (so far only demonstrated in animal studies): keratin extracted from sheep wool is a better scaffold for regrowing bone than the collagen we currently use. share.google/2Dbvjm1qjoSX...
Scientists turn sheep’s wool into a material that helps regrow bone
Keratin extracted from sheep’s wool helped damaged bone regenerate in animals, producing tissue that was more organized and structurally similar to healthy bone than tissue grown with conventional col...

Largely billionaires (unsurprisingly) but it's worth underlining never to support ActBlue again.
The "centrist" think tank Third Way is looking to pay someone between $140,000 and $150,000 to spend their days trying to dig up dirt on DSA members. They're trying to sell this gig as "anti-extremism" work, which I find completely disgusting.
If you need a 3D model of a Ma'agan Michael ship, a Kyrenia Ship, or an Athenian Trireme warship, you are in luck. I'd download them pretty quick though, this webpage seems to be in rapid decay. Sail on, digital ghosts. imareculture.eu/downloads/pr...

Megacorps have more invested more money into gen AI training than any other technology in the history of the world, but even they won't shell out for Springer articles.
Not only is AI cheating widespread & invasive among students like a cancer, we have this. It makes me want to bash my head into my desk repeatedly. www.chronicle.com/article/ai-i...
"It’s not just that the crystal is old. It’s that something this small and this fragile-looking has outlasted almost the entire physical Earth it formed on. Continents have assembled and broken apart, oceans have opened and closed, and entire mountain ranges have risen and eroded"

the ‘content creation’-ification of everything needs to be getting more pushback, I think it’s a straight line to considering everything ‘content’ to where we’re currently at with AI
there are more than twice as many museum workers in the US than there are coal miners
On my blog, I wrote about how America's museums are falling apart. The US has 20k+ museums, and most have historic buildings with leaky roofs, failing HVAC units, and flooding basements. What they don't have is money for repairs. Please read/share! 🧵 johngmarks.beehiiv.com/p/america-s-...
anyone know if the Liber Linteus will be continuing on to San Antonio?
thread of words without satisfactory etymologies (at least as known to me). a lot of them will probably be rocks and/or landforms
Se non è vero, è ben trovato... The Soleto Map may be the oldest map in Europe – though it is more likely a forgery. I still like it: it reads like a checklist of the extraordinary Messapian sites extensively researched in recent decades. Photo: @diffendale.bsky.social 🏺 #AncientBlueSky #Archaeology
"Niuno dubiterà per certo della vulcaneità di questa roccia."
Did you know that early Christian ascetics who gave "everything" away often retained a single slave? Just out, a new study by Erin Dailey and Justin Pigott: onlinelibrary.wiley.com/doi/10.1111/...
Ascetics, slaves, and necessity in Late Antiquity: renouncing all wealth, but for a single slave
Slave owners in Late Antiquity viewed the possession of at least one slave to be a necessity and a defining mark that distinguished the dignified social classes from the poor. Ascetics who shared thi...

It took six years, but at last I've given my website a revamp, and it's looking pretty. To mark the occasion, here's a new piece about the time an emperor gave the alphabet a revamp. Despite all his power and learning, it didn't work out. dannybate.com/2026/08/06/t...
The Emperor’s New Letters
When a Roman emperor updated the alphabet – and basically nobody listened to him. A common response to my profuse public pontifications about the history of the alphabet is ‘could we add new letter…
