Editor’s note: A version of this story appeared in CNN’s Wonder Theory science newsletter. Polar explorer Sir Ernest Shackleton and his crew of 27 men set off aboard the HMS Endurance in 1914. A search expedition found the HMS Endurance wreck in 2022, and now, another part of Shackleton’s legacy has been recovered. Central Press/Hulton Archive/Getty ImagesAn international team of experts using sonar has located the exploration ship Quest, once captained by Shackleton, off the coast of Canada. — A botanist spotted a tiny plant species new to science growing in an unlikely place on the slopes of the Andes.

☆ Scientists used AI to figure out elephants have names for themselves

Read previewScientists using AI tools have discovered that elephants likely have unique names for each other, according to a new study. A group of scientists used machine learning to analyze hundreds of wild African elephant calls recorded in Kenya between 1986 and 2022, publishing their findings on Monday in the peer-reviewed journal Nature Ecology and Evolution. They did not analyze other types of rumbles, like "let's go" rumbles, because elephants are less likely to use specific names in that context, the authors explained. Unlike dolphins and parrots, who address each other by mimicking the receiver's voice, these elephant calls are not imitations of what each elephant sounds like. And if the elephants have names for each other, it's also possible that they have names for other objects too, according to the study's authors.

☆ Every Elephant Has Its Own Name, Study Suggests

It’s more than a sound people make to get your attention — it’s a seemingly universal hallmark of human society and language, the specifics of which set us apart from our fellow animals. Now, scientists say they have found evidence with the help of artificial-intelligence-powered tools that elephants call each other by names too. Elephants’ trumpeting calls might be their most recognizable sounds, but these “are basically an emotional outburst,” Dr. Pardo said. Lower-pitched rumbles, he said, are more meaningful, as they make up a majority of elephant vocalizations and are used in a wide variety of social situations. “A lot of interesting stuff is going on in the rumbles,” he said.

☆ African elephants address each other with name-like calls, study suggests

CNN —Wild African elephants may address each other using individualized calls that resemble the personal names used by humans, a new study suggests. These elephants learn, recognize and use individualized name-like calls to address others of their kind, seemingly without using imitation, according to the study published Monday in the journal Nature Ecology and Evolution. Caregiver rumbles are used by an adolescent or adult female toward a calf she is caring for, according to the study. All the elephants could be individually identified by the shape of their ears, as they had been monitored continuously for decades, according to the study. The study authors were not able to conclusively determine whether different elephants used the same name to refer to the same individual, or if they addressed the same individual with different names.
