One of the world's oldest turds has been given the royal science treatment, with ancient Arctic ground squirrel droppings offering a smorgasbord of DNA from other animals and plants dating back up to 700,000 years.

Domesticated from a now-extinct ox species around 10,500 years ago, cows have become a major source of protein, dairy, and leather worldwide. A study has now shown that cows can differentiate between familiar and unfamiliar faces.

Advances in understanding of neuron activity and adaptation during squirrel hibernation could help inform stroke treatment and recovery.

One of the world’s most dangerous birds may carry signals invisible to the human eye. Scientists have found that the helmet-like casque atop a cassowary’s head fluoresces under UV light, revealing striking patterns that differ between species.

When escaped domestic pigs bred with wild boar after the Fukushima evacuation, researchers gained a rare chance to observe large-scale hybridization. The result offers a new lens on how fast-breeding traits can quietly reshape wildlife genetics.

The earliest ancestors of all backboned animals, including humans, may have viewed the world with four eyes, not just two, according to a new study. The remnants of those extra eyes persist deep in the human brain today as the pineal organ.

For more than a century, biologists assumed that the bony plates found in the skin of lizards – nature's chain mail – were an ancient feature that some lineages inherited and others later lost. But new evidence suggests this is entirely wrong.

Spelling F-O-O-D or O-U-T might only get you so far around your dog if he or she is considered a Gifted Word Learner. Researchers have just figured out that even when you're not talking to them directly, they're still acquiring new terms.

In a groundbreaking new study, scientists took a closer look at how bumble bees respond to positive experiences inside the nest. They found positive attitudes are quite literally contagious, spreading between bees within seconds.

In recent months, AI-generated wildlife clips have flooded social media, merging real animal behavior with playful fabrications but scientists warn that these digital deepfakes can distort people’s sense of what the natural world looks like.

At the bottom of the ocean, where metal-rich hydrothermal vents exhale poison, a bright yellow worm has mastered an impossible art: turning lethal elements into armor. Meet Paralvinella hessleri, the deep-sea super-worm that turns arsenic into crystal.

Large rock-face murals scattered across the desert represent one of the most ambitious – and perilous – creative feats of ancient humans, with researchers arguing the massive carvings acted as visual beacons, guiding people to crucial water sources.
