Scientists have identified when mammals became warm blooded about 233 million years ago, far later than once believed. By analyzing the inner ear canals of more than 300 living and extinct species, researchers found that the narrow structures linked to warm bloodedness emerged long after early cynodonts, reshaping our understanding of mammalian evolution.

A tiny invasive ant is rewriting African food chains. New research reveals how foreign ants caused lions to switch from hunting zebra to bison, demonstrating ecology's surprising interconnectedness.

Chia seeds, mathematics, and zebra stripes? Computer science students used sprouting seeds to test Alan Turing's 70-year-old theory about how nature creates its most striking patterns.

How do echidnas survive Australia's heat without sweating or panting? Thermal imaging reveals their secret cooling tricks, including nose bubbles that work like natural misters.
