Workers installing hammock poles on Michigan State University's campus in August 2023 unexpectedly unearthed the buried stone foundation of an old observatory. Built in 1881 and demolished in the 1920s, the small structure had been covered over for decades. Archaeologists and university staff identified the masonry as part of that 19th-century building, making it a notable historical find on a modern college lawn.

Fomenko’s thesis argues that much of what we call ancient history is misdated or duplicated and that the actual historical timeline is far shorter than commonly believed. Kasparov says he finds the questions it raises important and plans to spend more time promoting these ideas as he moves away from professional chess.

China’s state-run Global Times published an editorial urging the British Museum to return Chinese artifacts just ahead of a visit by UK Foreign Secretary James Cleverly. The piece accused the museum of holding items acquired through improper channels and called some pieces “stolen.” The British Museum’s collection includes more than 23,000 Chinese objects, and the editorial named examples such as the painting The Admonitions of the Instructress to the Court Ladies and Liao tri-coloured luohan statues.

So far, only Canada and the United Kingdom have pledged money, leaving roughly $40 million still needed to capitalise the fund ahead of COP16 next year.
