🏛️ Shipwreck surprises in Dubrovnik

This one is for all the Game of Thrones fans (side note: Q: how will you know if they’re a fan? A: Don’t worry, they’ve told you).

This week, an 18th-century shipwreck has been serendipitously discovered buried in the seabed of Dubrovnik's old port - the very same spot HBO fans know as "King's Landing."

This week, Croatian diver Ivan Bukelic made the remarkable find while working on a water pipeline project. According to CBS News, Bukelic discovered the vessel less than three feet under the seafloor and told reporters: "I can now say I discovered a boat at the Old Town Dubrovnik." You certainly can, Ivan.

Marine archaeologists confirmed that radiocarbon analysis has dated the vessel to the late 1700s, though the exact type of boat and its dimensions are still being determined. The discovery is particularly significant given Dubrovnik's rich maritime history as a major trading port.

I think it’s a pretty safe bet that this discovery will be included in the local Game of Thrones-themed walking tours.

Turing treasure survives the shredder

A good news story for anyone who's ever rescued something important from the bin - a treasure trove of scientific papers by codebreaking war hero Alan Turing has fetched about $1m at auction after being found in a loft and nearly shredded.

This week, the archive of works by the British mathematical genius went under the hammer after being discovered gathering dust at a London property. The papers, including letters from Turing's mother, had been gifted to his best friend Norman Routledge and were saved at the last minute when they were rediscovered during a family clear-out.

To clarify why these papers matter so much, Turing's work laid the foundation for artificial intelligence and modern computer science. During World War II, he played a critical role in breaking the Nazi's Enigma code, giving the Allies an advantage that helped shorten the war by around four years. You may have become familiar with Turing’s life through the 2014 film about his life starring Benedict Cumberbatch, ‘The Imitation Game’.

According to auctioneer Charles Hanson, some of the items were among the "most important" he's ever sold. He said: "To think these precious papers could've been lost to the shredder - and now they will go on to educate and inspire generations."

😊 Back on stage

It’s hard not to get shivers when watching Scottish singer-songwriter Lewis Capaldi make his triumphant return to the Glastonbury Music Festival, two years after taking a break to focus on his mental health.

Capaldi, who has Tourette's, last performed at the festival in 2023 under challenging circumstances, losing his voice and experiencing pronounced tics before the audience stepped in to help him finish his final song, Someone You Loved.

This weekend, Capaldi returned to the same stage, telling the crowd, "It's just a short set today, but I just wanted to come and finish what I couldn't finish the first time around. Second time's a charm on this one, everybody."

Just like in 2023, the performance became a beautiful back-and-forth with the audience, as Capaldi again leaned on the crowd as his co-singers when he performed Someone You Loved. Becoming emotional during the song, Capaldi said: "I couldn't sing this song two years ago. I might struggle to finish it today for different reasons."

It’s Capaldi’s first full-scale show in two years after announcing he was retreating from the spotlight to get his "physical and mental health in order" after the 2023 festival set. What an incredible reminder that sometimes the bravest thing you can do is take the time you need to heal.

💃 Whales discover a grooming tool

For the first time, researchers have documented killer whales using seaweed as tools for mutual grooming - a behaviour previously thought to be unique to primates, such as humans or apes.

This week, scientists published findings in Current Biology about a remarkable discovery made in the Salish Sea, where 73 killer whales have been observed biting off sections of bull kelp and rolling them between their bodies. According to Michael Weiss, research director at the Center for Whale Research and the study's lead author, "We realised we had stumbled across a newly described behaviour, which is remarkable."

It’s pretty incredible - pairs of whales select, trim and manipulate the kelp between them, possibly to remove dead skin or parasites. Researchers noted that it was usually observed between closely related whales, those of similar age, and those with excessive dead skin. That makes sense - it’s a pretty intimate exercise!

These Salish Sea killer whales are probably the most closely monitored marine mammals in the world, having been studied for 50 years before this behaviour was observed.
