More than 90% of popular freshwater game fish in Southern California harbor invasive parasites capable of infecting humans, according to new research from UC San Diego’s Scripps Institution of Oceanography. The study, published in the Journal of Infectious Diseases, reveals that fish species frequently caught and eaten by Americans carry large numbers of parasitic worms … Read more
A young Cooper’s hawk in New Jersey has learned to decode traffic signals, using the extended red lights triggered by pedestrian crossings as a hunting cue to attack songbirds with military precision. The remarkable behavior, documented by University of Tennessee researcher Vladimir Dinets, represents the most sophisticated use of human traffic patterns ever recorded in … Read more
Elephant-sized sloths once roamed from Alaska to Argentina, carving caves with massive claws and diving into oceans for seagrass meals. These ancient giants, some weighing 8,000 pounds, dominated the Americas for over 30 million years before vanishing around 15,000 years ago—just as humans spread across the continents. A new study published in Science reveals how … Read more
Scientists have discovered that vertebrate teeth originally evolved as sensory organs rather than just tools for eating, according to new research published in Nature that examined fossils dating back 470 million years. The study used cutting-edge synchrotron scanning technology to reveal that the earliest tooth-like structures in ancient fish were designed to detect environmental changes, … Read more
Vulnerable newborn humpback whales are entering the world much farther south than scientists previously thought, navigating busy shipping lanes and urban coastlines during their most fragile life stage. This surprising discovery challenges long-held beliefs about whale migration patterns and raises urgent questions about protecting these ocean giants during their earliest days. The UNSW-led study, published … Read more
A new report released on World Bee Day identifies twelve emerging threats that could accelerate pollinator losses over the next decade, with microplastics, conflict-driven crop simplification, and poorly planned climate actions topping the list. The findings from Bee:wild, a science-led global campaign, highlight how these novel dangers could compound well-established threats like habitat loss and … Read more
In the complex social world of mice, a newcomer can instantly size up a stranger’s social rank without ever having met them before. A new study from the Francis Crick Institute shows these rodents rely on their keen sense of smell to make quick social judgments – using chemical cues to decide whether to stand … Read more
On an island off Panama’s coast, scientists have documented a peculiar new behavior among white-faced capuchin monkeys that began with one curious individual and spread into a concerning cultural phenomenon. Using motion-triggered cameras, researchers captured young male capuchins abducting and carrying baby howler monkeys for days at a time—with no apparent benefit to themselves but … Read more
From the scorpion-hunting meerkats of the Kalahari to Kenya’s powerful hyenas, mammals with vastly different lifestyles appear to follow remarkably similar behavioral patterns, according to research published this week in the Proceedings of the National Academy of Sciences. The surprising findings suggest an underlying architecture that may organize how animals sequence their daily activities, regardless … Read more
A finger-sized marine predator with three eyes and an unusual respiratory system is challenging what scientists thought they knew about the early evolution of arthropods, the group that includes modern insects, crustaceans, and spiders. Canadian researchers have discovered Mosura fentoni, a 506-million-year-old creature from the famous Burgess Shale fossil beds, with an unprecedented body arrangement … Read more
