It seems almost certain that an asteroid impact wiped out the dinosaurs. But only almost. Another competing theory won’t completely go away: the extinction-by-volcano theory. A new study from the UK piles more evidence on the asteroid side of the debate, while adding a new volcanic twist. These researchers say that volcanic activity actually helped life recover

Deep within the hearts of Neptune and Uranus, it could be raining diamonds. Now, scientists have produced new experimental evidence showing how this could be possible. The hypothesis goes that the intense heat and pressure thousands of kilometres below the surface of these ice giants should split apart hydrocarbon compounds, with the carbon compressing into

Scientists confirmed that the submerged land mass, named Zealandia, was its own continent in 2017. But they hadn’t been able to map its full breadth until now. On Monday, researchers from GNS Science in New Zealand announced that they’d mapped the shape and size of the continent in unprecedented detail. They put their maps on an interactive website so that

The most severe extinction in Earth’s history looks to have been preceded and enabled by a colossal coal fire lit by volcanism over 250 million years ago, according to new research. The Permian-Triassic extinction, also known as the ‘Great Dying’, constitutes the deadliest of all our planet’s mass extinction events. When it took place, approximately

Diego the giant Galapagos tortoise whose tireless efforts are credited with almost single-handedly saving his once-threatened species, was put out to pasture Monday on his native island after decades of breeding in captivity, Ecuador’s environment minister said. Diego was shipped out from the Galapagos National Park’s breeding program on Santa Cruz to remote and uninhabited

Hummingbirds can perceive colours that the human eye cannot, thanks to the addition of an extra cone in the hummingbird’s eye that we don’t possess, new research reveals. The findings, demonstrated in experiments with wild broad-tailed hummingbirds (Selasphorus platycercus) in Colorado, suggest that the ability to discriminate non-spectral colours (including ultraviolet wavelengths) could play a

Scientists have developed a human embryo “blueprint” using human stem cells, in a breakthrough that could provide vital insight into the early stages of infant development, new research showed Thursday. Teams from the University of Cambridge and the Netherlands-based Hubrecht Institute said their model will allow them to observe never-before-seen processes underlying the formation of

The hailstone is so massive it even stunned meteorologists. “It’s incredible,” said meteorologist Matthew Kumjian from Penn State University in the US. “This is the extreme upper end of what you’d expect from hail.” The hefty ice lump smashed down from a supercell thunderstorm in Argentina two years ago, in the heavily populated town Villa Carlos

A single tail from one of the largest and most enigmatic dinosaur species looks to have solved a longstanding mystery about these extinct creatures: whether they could swim. The discovery of a giant fossilised tail belonging to the theropod Spinosaurus aegyptiacus suggests these huge predators were aquatic animals after all, using tail-propelled locomotion to swim
