Herbivore species dynamics is key to grassland food web stability In 2005, scientists began reshaping a semi-arid grassland in Inner Mongolia by changing its mix of plants. Years later, when researchers checked how the local food chain held together, plant-eating insects emerged as its strongest biological buffer.The long-term study, published on 18 July in the…

Tex had been raised in captivity and had imprinted on humans rather than other cranes, meaning she showed no interest in mating with her own…

Representative Image (AI-generated) Around 1200 BCE, several of the eastern Mediterranean’s most powerful civilisations, including the Mycenaean kingdoms, the Hittite Empire, Canaanite city-states and parts of New Kingdom Egypt, began experiencing a period of dramatic decline.

Two centuries ago, a British geologist gave the world its first named dinosaur. Megalosaurus, described from a handful of fossilised bones, marked the birth of an entire scientific field. Back then, researchers worked with little more than fragments, guesswork and imagination to picture prehistoric life. Fast forward 200 years, and palaeontology looks unrecognisable. Scientists no…
