Make a crocodile out of taffy. Take its head and tug on it until its neck extends a good few metres from its body. If you squint, this could be what one odd-looking Triassic reptile called Tanystropheus looked like. More or less.

NASA's Perseverance Mars rover launched from Cape Canaveral, Florida, on 30 July, carrying a host of cutting-edge technology including high-definition video equipment and the first interplanetary helicopter.

People have searched for sex differences in human brains since at least the 19th century, when scientist Samuel George Morton poured seeds and lead shot into human skulls to measure their volumes.

The dwarf planet Ceres was once assumed to be a fairly primitive chunk of rock. But just a few years ago, NASA's space probe Dawn revealed that there's more to this asteroid belt body than meets the eye.

More than 20 million coronavirus cases have now been registered across the world, over half in the Americas, according to an AFP tally of official sources at 2215 GMT on Monday.

One of the world's most prominent astronomical observatories has a hole.

A very long time ago, in the very early Universe, scientists have discovered a galaxy that seems way too advanced to have grown in the short timespan since the Big Bang. It's called SPT0418-47, and it's lurking 12.4 billion light-years away - when

The sudden dimming of one of the brightest stars in the night sky, Betelgeuse, could be due to a dust cloud spewing up from its surface, astronomers said on Thursday.

Greenland's ice sheet may have hit a tipping point that sets it on an irreversible path to completely disappearing.

We've found the fastest known star in the Milky Way. In the extreme environment at the centre of our galaxy, a newly discovered star called S4714 orbits the supermassive black hole Sagittarius A*.

NASA is actively monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest Africa.

Less than 2,000 miles from Earth.

Life was trying, but it wasn't working out. As the Late Devonian period dragged on, more and more living things died out, culminating in one of the greatest mass extinction events our planet has ever witnessed, approximately 359 million years ago.

Losing your senses of taste and smell is a common symptom of COVID-19 – patients have reported being unable to tell that they're wearing perfume or pick up on the nuance of a well-balanced dish.

NASA is tracking down the source of a minor air leak on the International Space Station. Crewmembers of the station's current Expedition 63 are in no immediate danger and will spend the weekend in the orbiting laboratory's Russian segment, inside the Zvezda…

The benefits of wearing face masks to help slow the spread of COVID-19 are now well understood, but scientists are still searching for better materials to use – and a filter 'paper' made up of titanium oxide nanowires is showing a lot of promise.

The sound of a key sliding into a lock could be enough information to potentially create a copy of that key and open the lock – that's the conclusion of researchers who've been investigating "acoustics-based physical key inference".

Aliens? Or a chunk of solid hydrogen? Which idea makes less sense?

The internet has transformed most areas of our lives over the last few decades, and the technology keeps improving: researchers just set a new record for data transmission rates, logging an incredible speed of 178 terabits per second (Tbps).

Researchers in Hong Kong Monday identified what they said was the first confirmed case worldwide of COVID-19 reinfection, raising questions about the durability of immunity, whether acquired naturally or with a vaccine.
