For nearly three decades, the Sun seemed to be winding down. Sunspot counts fell, the solar wind weakened, and by 2008 our star had reached its faintest measured state since satellites began watching it. Astronomers braced for a repeat of history’s great solar lulls, centuries-long stretches when the Sun barely stirred. Then, quietly, the numbers…
Credit: Erik Karits from Pexels Hummingbird hawkmoths may have their own version of being left-handed or right-handed, using one preferred eye and one side of their long feeding tube together to search flowers for nectar.The discovery, made by a team of biologists at the University of Konstanz, shows how creatures with small brains save mental…
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…
King ratsnake is known for hunting and eating deadly venomous snakes (Inaturalist photos) A nonvenomous snake that regularly hunts and eats some of the world’s most dangerous venomous snakes has given scientists a new mystery to solve.

A researcher following scuba divers for this project Most scuba divers believe they rarely touch fragile seabed ecosystems, yet underwater observers tracking hundreds of tourists found that more than 40 per cent of their physical contacts caused visible damage to living coral structures.Research published in The Conversation by marine scientists and dive professionals revealed that…
Two hundred years ago, you wouldn’t have been able to find them outside of South America. But since then, Nutria, one of the world’s largest rodents, has taken over US. These rodents were initially brought to North America in the late 19th and early 20th centuries, primarily for fur farming, since their soft underfur was…
In 1976, ornithologist George Archibald began an unusual daily ritual, dancing beside a whooping crane named Tex in an attempt to save one of the rarest birds on the planet. 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…
Florence Nightingale is remembered as the founder of modern nursing, but her influence reached far beyond hospitals and healthcare. Through discipline, compassion and a determination to improve lives, she changed the way patients were treated and helped shape modern medicine.

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…
