‘I was screaming’: Scientists shocked as dolphins filmed using shells to trap prey for the first time | New York Post Researchers are shell-shocked at the latest marine discovery. Dolphins have been filmed using shells to ensnare their prey off the coast of Australia, marking the first time this clever tactic has been caught on camera, per a bombshell paper in Marine Mammal Science. “The second I saw that shell in the air, I immediately knew what was happening,” the study’s head author, Alexis Levengood, a marine mammal biologist at the University of the Sunshine Coast in Queensland, told ScienceAlert. Levengood said she and her team were on a research vessel off Hervey Bay when they spotted a female Pacific bottlenose “dolphin raising something large out of the water,” the BBC reported. She instantly recognized the behavior as “shelling,” when dolphins flush prey into a large empty seasnail shell. Then, the impromptu fish trap to the surface and drains the quarry into their mouths like a fishy oyster shooter. In the dramatic clip captured in 2025, the brainy cetacean can be seen holding a shell aloft, and then dropping it in the water, before snatching up a fish that escaped its calcified prison. “I was screaming to the students that were on the boat with me in excitement, because I was just so excited that we were actually witnessing this here on the east coast,” exclaimed Levengood. While the behavior had been observed in 2013 in Shark Bay, Western Australia, this was the first video evidence of the ingenious prey-snatching method. And this wasn’t some fleeting party trick, either. In another clip from Hervey Bay, a mother and a calf could be seen shelling together, demonstrating that the behavior is passed down from generation to generation and not between peers as previously believed. “We saw the mother surface with a shell, the fish inside escaped and the dolphin dropped the shell to chase the fish,” said Levengood. “Then, minutes afterwards, the dolphin calf picked up the shell and held it the same way as its mother.” While it’s yet unclear if either was successful in their trapping efforts, the scientist said the “footage provides the first potential evidence of maternal social transmission — a process by which offspring learn behavior by observing the actions of their mother.” When coupled with the observations from 2013, this eye-opening footage demonstrates how populations of dolphins learned to use tools in the exact same manner despite being thousands of miles apart. “They may have both invented this or innovated this independently of one another, or it’s even possible that there might be some populations up north that are doing this that we don’t even know about yet,” Levengood told Science Alert. She concluded that either way, “these findings highlight just how smart, clever, and innovative dolphins are.” On a larger scale, shelling could also help shed light on how humans evolved to use tools as well. “But better understanding of shelling and other tool use in non-human animals will continue to teach us more about ourselves and how and why we evolved the way we did,” said Levengood.

OK, I have a definitive word on the CJ Abrams play from today's Pittsburgh Pirates at Washington Nationals game after talking with Elias Sports Bureau on this. This play will stay as a sacrifice fly. The originial ruling of NOT a sacrifice fly was for the exact same reason that I thought, which is that the infielder is not running into the outfield, which is year's past would have been correct As it was explained to me, in past years, an infielder had to be running almost in a straight line towards the outfield wall to be considered "running in the outfield". Here, since he is running, and he ends up further away from home (157 feet) than when he started (145 feet), this is going to count as a sacrifice fly. That definition is changing, in part from this play to help bring greater consistency, and to take some of the guesswork out of it (the argument that he is running into the outfield as opposed to more parallel). Now, folks all the time ask "why doesn't MLB publish the OS Manual" and I always say because it is a living document that can have the wording change, and the wording for this play will be modified to something like "more towards the outfield wall than towards home plate" to eliminate any confusion. The big key to this play is that he was running on a full sprint. Also, and this is helpful for me, but for all fly ball outs that score a run, Elias Saba reviews to ensure consistency. So, yes, it's a sacrifice fly, and now that I have that info from Elias themselves, that sort of settles this one. Sounds like the guidelines for this definition will be changing, either this season, or certainly for next season.

She Lived to 117. Scientists Studied Her for Months. Her Secret Cost $2. Maria Branyas Morera ate three yogurts a day. Every single day, for as long as anyone could remember. She mentioned this to anyone who asked about her longevity, which was often, and it was the kind of advice people receive with a warm smile and then immediately discard, because we prefer our longevity secrets to involve something more exotic than a supermarket dairy aisle. Maria died in Barcelona in 2024. She was 117. Then scientists actually looked inside her, and the smiling stopped. Her gut was packed with Bifidobacterium, a bacterium almost never found in people past 110, and far more commonly associated with infants. Her body had, in the most literal biological sense, not been informed of her actual age. It was operating on entirely different assumptions. Her DNA suggested she was somewhere between 100 and 110. She was 117. Seven years younger on the inside than the calendar insisted, which at 117 is not a rounding error. That is a extraordinary number. But to appreciate why any of this matters, you need to understand what kind of person we are talking about. Maria was born in San Francisco in 1907, the year before the Model T Ford, when Theodore Roosevelt was still in the White House and most of humanity died of things we now treat with a Tuesday afternoon at the pharmacy. Her Catalan father had come to America to make something of himself, and for a while it worked beautifully. He founded a Spanish-language magazine in New Orleans, one of the most chaotic, beautiful, swampy, and gastronomically unhinged cities on the continent, a place that has always operated on the reasonable philosophy that life is uncertain and the gumbo is excellent. Then the family got on a boat back to Spain. Maria fell on deck and permanently lost the hearing in one ear. Her father died of tuberculosis before the coast of Catalonia came into view. He was 37. She was eight. Her mother arrived in Europe with five children, no husband, and presumably very little appetite for what came next. Maria managed. She nursed soldiers in the Spanish Civil War. She outlived Franco, which required considerable patience. She raised three children. She played piano until she was 108. At 113 she caught COVID-19 and dispatched it, which at that point resembles less a medical event than a statement of intent. Then she joined Twitter. Her bio read: “I am old, very old, but not an idiot.” Her last request, before she died peacefully in her sleep, was three words: “Please study me.” The geneticists obliged with considerable enthusiasm, and their subsequent paper in Cell Reports Medicine runs to forty pages of scientists explaining, in the careful and hedged language that science requires, that this woman was remarkable in ways they had not previously encountered and were not entirely sure how to explain. The yogurt, it turns out, had been doing quiet and serious work for over a century. Nomadic peoples of Central Asia were fermenting milk 8,000 years ago, long before germ theory, before microscopes, before anyone had the faintest idea what a bacterium was. They didn’t need to understand it. Their guts understood it. The knowledge was older than writing. Maria understood it too. She didn’t publish a paper. She didn’t launch a wellness brand. She just ate her yogurt every morning and got on with the extraordinary business of being alive. Gandalv / Gandalv ✦ AI-generated image. Not the actual person. Full story:
