A ship sails through the Lemaire Channel in Antarctica (AP file photo) A new study has found that several former Antarctic tour guides decided to leave their jobs because they could no longer balance their love for the continent with the environmental impact of the tourism industry. Researchers spoke to 25 former guides who said…
Researchers clipped a few wing and tail feathers of wild Alaskan kittiwakes (AI enhanced image. Credit: Nature Counts) Researchers who clipped a few wing and tail feathers of wild black-legged kittiwakes in Alaska to make flying harder, have found that the effects lasted well beyond a single breeding season. The birds struggled to raise chicks…
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…
Dutch microbiologist Professor Henk Jonkers holds a sample of self-healing concrete, an innovation that uses bacteria to repair cracks automatically. Concrete is the backbone of modern civilisation, supporting everything from homes and skyscrapers to bridges, tunnels and dams. Yet even this remarkably strong material has a costly weakness. Tiny cracks inevitably develop over time because…
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. Among her many memorable sayings, one quote continues to inspire people across generations: “I attribute…
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…
Image Credit: guinnessworldrecords.com Shark is a unique animal that has survived five mass extinctions and swam in our oceans before trees existed. For many of us, the thought of a shark brings up the images of big, sharp teeth with terror. However, for one American marine biologist named ‘Emily Morrison,’ these marine predators are not…
A female typically mates with five males simultaneously, although groups of 10 to 15 are not unusual Female African treefrogs mate with several males at the same time, working together to whip up a larger foam nest that protects hundreds of eggs from drying out.This group nest-building behaviour provides a fresh explanation for why females…
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…
