66 million years ago, a great big rock hit the Earth and killed off all the dinosaurs (except birds). Turns out the killer chunk originally formed in the outer solar system, beyond the orbit of Jupiter. www.nature.com/articles/d41586-024-… #science #scientist

Geologists have spent decades figuring out when plate tectonics began - and got wildly contradictory results. As one said: “You can have 30 people with 30 different specialisms and we will probably come up with 30 different numbers." www.nature.com/articles/d41586-024-… #science […]

Scientists had long suspected that the Chicxulub impactor, which caused the end-Cretaceous extinction, was an asteroid from the outer Solar System. New geochemical observations bolster the case. www.nature.com/articles/d41586-024-… #science #scientist

In early October 1993, local researchers were exploring Lamalunga cave in Italy when they stumbled upon a hominin skeleton. It’s 31 years later and the skeleton is still there, still entombed. www.newscientist.com/article/244339… […]

So many studies try to pin down the date when plate tectonics began on Earth. But in fact it probably started in a stepwise way, so there is no single date. www.nature.com/articles/d41586-024-… #science #scientist

You know the object that smashed into Earth and kick-started the extinction that wiped out almost all dinosaurs 66 million years ago? It was an asteroid that originally formed beyond the orbit of Jupiter. www.nature.com/articles/d41586-024-… #science #scientist

Researchers have spent decades hunting for clues about the origins of plate tectonics, the process that moves the continents around. Now a new kind of answer is coming into focus. www.nature.com/articles/d41586-024-… #science #scientist

A tiny chunk of plant resin shows humans were living on an island in eastern Indonesia at least 55,000 years ago – revealing the likely route that modern humans took when migrating to Australia […]

We know that modern humans took one of two routes to first reach Australia. Now an ancient chunk of plant resin has tipped the evidence towards the northern option. www.newscientist.com/article/244353… #science #scientist

This tiny 700,000-year-old arm bone from the island of Flores in Indonesia may have belonged to an ancestor of the "hobbits", Homo floresiensis, that lived on the island more recently […]

Hominins living on an Indonesian island 700,000 years ago were even smaller than Homo floresiensis, the so-called hobbits that lived on the same island much more recently. www.newscientist.com/article/244268…

An arm bone from an ancient human that lived 700,000 years ago on the island of Flores is the smallest ever found from an adult hominin. The bone adds a new piece to the puzzle of the "hobbits" Homo floresiensis […]

Oh gods, the first episode of season two of #HouseOfTheDragon repeats the *exact* mistake the finale of season one made It’s not dramatic to horrifically kill off a character if we don’t know their name or anything about them It has shock value but it's ultimately empty #science #scientist
