Half-ton early bovines roamed 4-million-year-old grasslands in Europe
Half-ton early bovines roamed 4-million-year-old grasslands in Europe Robert Egan Associate Editor The first large-sized bovines grew to up to half a ton 4 million years ago in the European Early Pliocene, an early step toward our modern diversity of large-bodied buffalo and cattle, according to a study published June 3, 2026, in the open access journal PLOS One by Leonardo Sorbelli of the Leibniz Institute for Evolution and Biodiversity Science, Germany, and colleagues. Bovines are major...
Q&A: Ancient bird species found in China's Liaoning had extra-long tail feathers for elaborate courtship
Ancient bird species found in China's Liaoning had extra-long tail feathers for elaborate courtship Sadie Harley Scientific Editor Robert Egan Associate Editor A recently discovered extinct bird from the early Cretaceous Period (approximately 121 million years ago) may have waggled its long tail feathers to attract mates, according to a study published May 27, 2026 in the open-access journal PLOS One by Alexander Clark of the University of Chicago and colleagues. Clark shares more details...
Whatever the mirror test tells us, beluga whales pass it
In hours of underwater video footage from a New York aquarium, a beluga whale named Natasha stretches her neck, pirouettes, nods, and shakes her head in front of a two-way mirror. Her daughter Maris does much the same. According to a new study published in PLOS One, both animals show the behavioral hallmarks of mirror self-recognition—a cognitive ability long considered a marker of self-awareness, and one that had never before been documented in beluga whales.
Wonderwerk Cave bones reveal possible fire use by human ancestors 1.79 million years ago
June 7, 2026 report Wonderwerk Cave bones reveal possible fire use by human ancestors 1.79 million years ago Paul Arnold Author Gaby Clark Scientific Editor Robert Egan Associate Editor The discovery of fire was a major milestone in human evolution, giving our ancestors a way to stay warm, ward off predators, and eventually start cooking food. But exactly when this first happened is still intensely debated, as unambiguous evidence is difficult to find. However, new research from a cave in...
Billions are going into fish passage projects, but planning methods can undercut results
Billions are going into fish passage projects, but planning methods can undercut results Sadie Harley Scientific Editor Robert Egan Associate Editor Fish that split their lives between fresh and salt water often face obstacles getting back and forth. Dams and roads fracture river networks and interfere with traditional migratory routes, sparking concerns about fish health and abundance, as well as biodiversity on a broader scale. Efforts to restore fish passage are cropping up across the...
Majestic manta rays dive deep to survive storm events, data reveal
Majestic manta rays dive deep to survive storm events, data reveal Sadie Harley Scientific Editor Robert Egan Associate Editor New research led by the University of the Sunshine Coast has found that reef manta rays are diving deep in storm events to find food and stay alive. As World Environment Day is celebrated around the globe on June 5, the findings offer hope for the future of a species listed as vulnerable to extinction. Lead author Anna Knochel said the team was surprised to record no...
Endangered basking sharks rely on the ocean twilight zone during long-distance migrations
Endangered basking sharks rely on the ocean twilight zone during long-distance migrations Lisa Lock Scientific Editor Robert Egan Associate Editor Endangered basking sharks aren't fasting during long-distance migrations. A new study led by the Woods Hole Oceanographic Institution shows that they may be foraging along the way, and in much deeper areas of the ocean than previously thought. As filter feeders, this species is most often observed close to the surface, especially in waters off of...
Traditional, patriarchal Japanese terms for husband and wife may now be perceived as neutral
Traditional, patriarchal Japanese terms for husband and wife may now be perceived as neutral Sadie Harley Scientific Editor Robert Egan Associate Editor A new study suggests that, for modern Japanese speakers, two traditional, patriarchal words for "husband" ("shujin," literally meaning "master") and "wife" ("kanai," "inside-the-house") may be losing their original meanings, though men in the study evaluated both traditional and neutral words for "husband" more positively than words for...
Printed manga may give the brain a storytelling advantage
Printed manga may give the brain a storytelling advantage Robert Egan Associate Editor A new study by researchers at the University of Tokyo explores whether reading manga on paper or on a tablet changes how the brain understands and remembers stories. Participants first read the opening half of a two-part manga story either on paper or on a tablet. Later, while inside an MRI scanner, they read the second half through LCD goggles and answered questions about the story.
A 5.3-million-year-old deep-sea whale necropolis in the Diamantina Zone
Abstract Whale falls are biodiversity oases at seabeds1,2,3,4,5,6, yet their record from the oceans has remained sparse and fragmentary6,7. Here we report the discovery of a vast whale necropolis in the Diamantina Zone (4,616- to 7,001-m depth), extending about 1,200 km along the sea floor of the southeastern Indian Ocean. This area has a deep and extensive accumulation comprising five modern natural whale-fall communities and 476 fossil cetaceans recorded.
