Two hundred ancient mammoth skeletons have been discovered beneath an airport construction site north of Mexico City – the largest collection of mammoth bones ever found. Archaeologists at Mexico’s National Institute of Anthropology and History first realised the area might hide mammoth remains after they found two human-dug mammoth traps in November as part of

A bubble of methane gas, swelling beneath Siberia’s melting permafrost for who knows how long, has burst open to form an impressive 50-metre-deep (164-foot-deep) crater. The giant hole was first spotted by a TV crew flying overhead, and, according to The Siberian Times, when scientists went to investigate, they found chunks of ice and rock thrown hundreds

Animals have been hibernating for a long, long time, a new study shows. Researchers have analysed 250 million-year-old fossils and found evidence that the pig-sized mammal relation, a genus called Lystrosaurus, hibernated much like bears and bats do today. Finding signs of shifts in metabolism rates in fossils is just about impossible under normal conditions – but

An international team of marine scientists have discovered 30 new species of invertebrates in deep water surrounding the Galapagos, the Ecuadoran archipelago’s national park authorities announced Monday. The deep-sea experts discovered fragile coral and sponge communities including 10 bamboo corals, four octocorals, one brittle star and 11 sponges – as well as four new species

We think of sharks as solitary creatures. Lurking silently beneath the waves, each single toothy predator operating alone, coming together only temporarily as feasting or mating dictates. We may, however, be totally wrong. According to new research, sharks could be forming large social groups from which smaller numbers break off to forage, and then return

Earthquakes come and go, often leaving a trail of devastation in their wake. What they don’t usually do, thankfully, is turn around immediately and come back for another pass. Except… it looks like they can, in exceedingly rare circumstances. In a new study, scientists have found evidence of an unusual and virtually unprecedented ‘boomerang’ earthquake

A long-extinct lineage of insect, known fondly as the ‘hell ant’, has been discovered frozen in 99-million-year-old amber, with its scythe-like jaw still pinning its prey. According to scientists, this fierce predator is a newly identified species of prehistoric ant, known as Ceratomyrmex ellenbergeri, and it’s the first time we’ve ever seen a hell ant actively

As if spiderwebs weren’t already icky enough, some spiders have gone and made them poisonous as well, a new study reveals. The unique properties of spiderwebs have long fascinated materials scientists. They’re constructed from one of the toughest known natural materials: lighter, yet five times stronger than steel, and bacteria resistant to boot. Spider silk is also
