An ancient sea once divided North America from north to south; 70-million-year-old creatures from its waters still shimmer like gemstones

Fossils from this period are displayed at the Smithsonian’s National Museum of Natural History. South Dakota is one of the most landlocked states in the United States. It is more than 1,000 miles away from both the Pacific and Atlantic oceans. It is hard to imagine that this dry landscape was once covered by water.But…

A Maya astronomer studied the movements of Venus and Mars in AD 781, and archaeologists have now discovered his name |

For centuries, the ancient Maya have been celebrated for their remarkable achievements in astronomy, mathematics and calendar-making. They tracked the movements of planets with extraordinary precision, developed one of the world’s earliest concepts of zero and created complex calendars that guided agriculture, religion and governance. Yet the brilliant minds behind these discoveries have largely remained…

Emperor penguins survive Antarctica’s brutal winters by huddling together, but a maths study reveals the hidden system behind their remarkable teamwork |

Every winter in Antarctica, emperor penguins gather in large groups called huddles to survive the cold. Temperatures can fall to -40 degrees Celsius, and strong winds make the weather even harsher. Without huddling together, these penguins would not be able to survive.But a penguin huddle is much more than a group of birds standing close…

Scientists have finally explained why killer whales struggle to hear blue whales, and the answer may have helped the giants survive for millions of years |

Whales are well known for their songs. But scientists have discovered that, for some whales, those songs may also help them stay alive. A researcher from the University of Washington has found that some baleen whales, including blue, fin and minke whales, have evolved to sing at such low frequencies that killer whales, their only…

40-gram, palm-sized AI micro-drone kills a flying insect autonomously in mid-air for the first time. Now it could eradicate mosquitoes and save thousands of lives |

A palm-sized AI drone weighing just 40 grams has achieved an engineering first by autonomously hunting and killing a flying insect in mid-air, paving the way for a new approach to mosquito control. Developed by US startup Tornyol, the tiny drone successfully detected, tracked and intercepted a flying moth during a controlled indoor demonstration without…

Quote of the day by Charles Darwin: “An American monkey, after getting drunk on brandy, would never touch…” – a witty observation on why humans often repeat the mistakes they already know can harm them |

Charles Darwin (Image source: Wikipedia) A bad experience is supposed to teach a lesson, yet people return to habits they already know are harmful more often than logic would suggest. Charles Darwin noticed the same contradiction and put it more bluntly than most. “An American monkey, after getting drunk on brandy, would never touch it…

Are data centres harming bees? Scientists are investigating the impact of electromagnetic fields |

Bees are among the world’s most important pollinators, helping sustain ecosystems and supporting the production of many fruits, vegetables, nuts and seeds. Yet bee populations have been declining for years due to habitat loss, pesticides, diseases, parasites and climate change. More recently, another potential threat has entered the conversation: the rapid expansion of data centres….

Scientists cut climbing vines from a damaged Borneo forest. Its canopy then grew three times faster, and the method may cost 10 times less than tree planting

Dipterocarp forest at the Danum Valley Field Centre. Borneo’s tropical forests, dominated by trees from the Dipterocarp family, have some of the highest canopies in the world, with some trees reaching 100 meters Simply cutting back aggressive climbing vines in logged tropical forests allows the tree canopy to recover three times faster than planting new…
