The extreme appetite for ants and termites has independently emerged in mammals at least 12 separate times over the past 66 million years, according to new research that reveals one of evolution’s most unusual dietary obsessions. Scientists at New Jersey Institute of Technology traced this specialized feeding strategy across thousands of mammal species, discovering that … Read more
Fitness trackers attached to wild bearded dragons have revealed a counterintuitive finding that challenges assumptions about animal survival. The fastest lizards were actually more likely to die than their slower counterparts, according to a year-long study that monitored 40 Australian central bearded dragons in their natural habitat. Researchers from the University of Melbourne fitted the … Read more
When wildfires scorched half of Brazil’s northern Pantanal in 2020, researchers expected to find fewer jaguars in their long-term study site. Instead, they discovered something remarkable: the wetland had become a magnet for the big cats, drawing immigrants from fire-ravaged areas and boosting the local population to even higher densities. The finding suggests this corner … Read more
Giant tortoises can weigh hundreds of kilograms and live over 150 years—conditions that should make cancer inevitable. Yet new research reveals these ancient reptiles develop cancer at remarkably low rates, with only 1% of individuals affected compared to much higher rates in mammals and birds. The findings could unlock secrets for preventing cancer in humans. … Read more
Most predators leave bones behind when they eat, but Burmese pythons swallow their prey whole—skeleton and all. Now scientists have discovered how these massive snakes accomplish this feat: they’ve evolved specialized intestinal cells that capture excess calcium and phosphorus from dissolved bones, preventing potentially fatal mineral overload. The discovery, published in the Journal of Experimental … Read more
When domesticated rabbits escape captivity and establish wild populations, they don’t simply revert to their ancestral forms—instead, they develop distinct anatomical features never seen in either wild or domestic rabbits. A comprehensive study of 912 rabbit skulls from around the world reveals that feralisation creates novel evolutionary pathways, with escaped domestic rabbits occupying an intermediate … Read more
A small band of prairie dogs that survived one of nature’s most devastating bacterial killers has revealed genetic secrets that could reshape how scientists approach wildlife disease outbreaks. These Colorado survivors carry DNA variants that helped them withstand sylvatic plague—the same pathogen that caused the Black Death in medieval Europe. When plague swept through Boulder … Read more
What looks effortless isn’t always easy. When fish hang motionless in the water column, they appear to be resting—but new research reveals they’re actually working twice as hard as scientists previously thought. A comprehensive study of 13 fish species shows that hovering burns nearly double the energy of true rest, overturning decades of assumptions about … Read more
Two-thirds of domestic cats prefer to sleep on their left side, according to research analyzing hundreds of YouTube videos—a seemingly quirky finding that reveals a sophisticated evolutionary survival strategy. Scientists believe this sleeping preference gives cats a crucial advantage when detecting threats or prey upon awakening, as their left visual field connects directly to the … Read more
Deep in the tropical understory, millions of leafcutter ants march in perfect synchrony—some slice leaves with surgical precision while others tend nurseries or stand guard at colony gates. Now scientists have cracked the chemical code behind this extraordinary social organization, discovering that just two molecular switches can completely reprogram an ant’s life purpose. University of … Read more
