(CNN) — No species lasts forever — extinction is part of the evolution of life. But at least five times, a biological catastrophe has engulfed the planet, killing off the vast majority of species from water and land over a relatively short geological interval. The most famous of these mass extinction events — when an

(CNN) — Scientists have created tiny living robots from human cells that can move around in a lab dish and may one day be able to help heal wounds or damaged tissue, according to a new study. A team at Tufts University and Harvard University’s Wyss Institute have dubbed these creations anthrobots. The research builds

(CNN) — Space scientists seeking to understand the enigmatic origins of powerful cosmic rays have detected an extremely rare, ultra-high-energy particle that they believe traveled to Earth from beyond the Milky Way galaxy. The energy of this subatomic particle, invisible to the naked eye, is equivalent to dropping a brick on your toe from waist

(CNN) — Scientists based in China have created a monkey chimera with two sets of DNA, experimental work they say could ultimately benefit medical research and the conservation of endangered species. The monkey, which lived for 10 days before being euthanized, was made by combining stem cells from a cynomolgus monkey — also known as

(CNN) — The age of the dinosaurs ended 66 million years ago when a city-size asteroid struck a shallow sea off the coast of what is now Mexico. But exactly how the mass extinction of 75% of the species on Earth unfolded in the years that followed the cataclysmic impact has remained unclear. Previous research

(CNN) — Reports of “earthquake lights,” like the ones seen in videos captured before Friday’s 6.8-magnitude earthquake in Morocco, go back centuries to ancient Greece. These outbursts of bright, dancing light in different colors have long puzzled scientists, and there’s still no consensus on what causes them, but they are “definitely real,” said John Derr,

(CNN) — The fossil of a tiny bird-like dinosaur with surprisingly long lower legs has been discovered in China. The creature would have lived during the Late Jurassic Period 148 million to 150 million years ago in what’s now Fujian province in southeast China. Named Fuijianvenator prodigiosus, which means “bizarre hunter from Fuijian” in Latin,

Early humans left Africa and reached Asia earlier than thought, fossil discovery reveals

Katie Hunt, CNN — Wed, 14 Jun 2023 03:40:38 +0000

(CNN) — Humans originated in Africa, but when exactly our earliest ancestors left the continent and how they spread around the world has been intensely debated by archaeologists. Two fossils unearthed in a cave in northern Laos suggest that Homo sapiens, our own species, was living in the region some 86,000 years ago, according to a
