Jaguars Flood Into Brazilian Wetlands After Massive Wildfire

Jaguar in Pantanal region of Brazil.

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

Turtles Rarely Get Cancer Despite Living 150+ Years

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

Feral Rabbits Don’t Just Go Wild — They Evolve Into Something Entirely New

feral rabbit

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

Prairie Dogs Found With Genes That Beat the Black Death

A juvenile black-tailed prairie dog emerges cautiously from its burrow in Boulder County, Colorado.

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

Fish Hovering Burns Twice the Energy Scientists Expected

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

Cats Sleep on Their Left Side for Evolutionary Advantage

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

How Two Tiny Molecules Control Ant Society’s Division of Labor

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

Antarctic Leopard Seals Show Surprising Individual Hunting Habits

Leopard seal in the Western Antarctic Peninsula

Most leopard seals are dietary specialists despite their reputation as generalist predators, according to new research that reveals how individual hunting strategies can dramatically reshape Antarctic ecosystems. The findings suggest a small number of specialist hunters may have driven the collapse of local Antarctic fur seal populations. Scientists analyzed whisker samples from 34 leopard seals … Read more

Being Nosy Runs Deeper Than We Thought

Ngamba Island Chimpanzee Sanctuary in Uganda

Ever catch yourself people-watching at a coffee shop, fascinated by the couple arguing at the next table? That urge to know what’s happening in other people’s lives isn’t just a quirky human habit—it’s a deep-seated curiosity we share with our closest primate relatives. A groundbreaking study reveals that chimpanzees are just as invested in social … Read more

Scientists Crack the Code for Bonobos Facial Expressions

Bonobos can make 28 distinct facial movements, from subtle nostril flares to dramatic lip funneling, according to new research that finally gives scientists a systematic way to decode our closest relatives’ complex emotional lives. The study represents the first comprehensive analysis of bonobo facial expressions using standardized scientific methods. An international research team successfully adapted … Read more
