We’re finally reading the secrets of Herculaneum’s lost library A whole library’s worth of papyri owned by Julius Caesar’s father-in-law were turned to charcoal by the eruption of Vesuvius. Nearly 2000 years later, we can at last read these lost treasures

It feels like this is something that AI should be doing, insofar as it "should" be doing anything. It's helping to read and translate carbonised Roman scrolls recovered from Herculaneum, which was destroyed in the Vesuvius eruption.

The French far right’s financial Catch-22 The National Rally is under investigation in a string of cases that all point to the same problem: how it funds itself.

The far-right National Rally has never been more popular, and stands a realistic chance of winning the presidency when the next election is held in 2027

But it remains constantly dogged by legal troubles. I looked into why ⤵️

The billionaire and the tax evading gift shops Asif Aziz's Criterion Capital manages a row of high-profile shops at Piccadilly Circus. So why does his team keeping renting them to students who vanish without paying millions of pounds in taxes?

Outstanding reporting from London Centric, digging into tourist-tat gift shops that rotate “directors” and avoid paying millions in taxes. I’d tell visitors to avoid these places but it can be difficult to tell which ones are legitimate.

The truth about de-extinction: is it even possible, and why do it? Ambitious projects aim to put dire wolves, woolly mammoths and passenger pigeons back into our ecosystems. But with so many technical and ethical hurdles, what is the real motivation?

No, dire wolves are not back from extinction.

Ancient DNA reveals make-up of Roman Empire’s favourite sauce Bones found at the site of an ancient fish-processing plant were used to genetically identify the species that went into a fish sauce, often known as garum, eaten throughout the Roman Empire

Garum, a fermented fish sauce, was something like the Roman Empire's version of ketchup, in terms of how much it was eaten. Thanks to DNA testing, we now know what kind of fish went into it.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

I also feel compelled to point out that (as of 2018-ish when I last visited) Antwerp's zoo has both raccoons and skunks living together in an actual habitat, complete with overturned open barrels to approximate trashcans.

I assume that's because they wash their food before eating it. Is that right or is there a different reason?!
