Humans have evolved big, energy-hungry brains that require us to consume many more calories than our closest animal relatives. The same, however, does not appear to hold for our water intake.

More and more, it seems that the existence and persistence of life on Earth is the result of sheer luck. According to a new analysis of the history of the Milky Way, the best time and place for the emergence of life isn't here, or now, but over 6 b

They say beauty lies in the eye of the beholder, but in actuality, it goes far deeper than that.

New insights into the neural activity linked to loneliness could help us improve the way we treat it, researchers say – and reduce the numerous physical and mental health impacts associated with feelings of being lonely.

The sea is rising, but that's not all. Scientists say current assessments of global sea-level rise have disregarded an important phenomenon affecting coastal regions – an oversight that means the ongoing specter of sea-level rise is even more omi

The bundle of instruments known as SuperCam on board the Perseverance Mars rover has collected its first samples in the hunt for past life on the red planet, mission scientists said Wednesday.

We've all been Confused Travolta.

For the millions of us plagued by hypersensitive, overactive, or downright abusive immune systems, it can feel like you're constantly fighting your own physical self.

The largest asteroid to pass by Earth this year will approach within some 1.25 million miles (two million kilometers) of our planet on March 21, NASA said Thursday.

For decades, we've dreamed of visiting other star systems. There's just one problem – they're so far away, with conventional spaceflight it would take tens of thousands of years to reach even the closest one.

Five years after its discovery, one of the Milky Way's most exciting exoplanets just got even more intriguing. GJ 1132 b, once hailed as one of the most important planets outside the Solar System, appears to have lost its atmosphere - and has since

New theories of wormholes—postulated tunnels through spacetime—explore whether they could be traversable by humans.

It's tricky to figure out what Earth might have looked like in the early years before life emerged. Geological detectives have now obtained more evidence that it was rather different to the planet we live on today.

Oxygen is life to animals like us. But for many species of microbe, the smallest whiff of the highly reactive element puts their delicate chemical machinery at risk of rusting up.

The question of how life on Earth got started has long intrigued us, and new research suggests that primordial lightning strikes – perhaps over the course of a billion years – could have played a crucial role in sparking life on this planet.

The origin and identity of a massive space object that careened past Earth in 2017 have remained a mystery ever since.

Vaccines are amazing, life-saving innovations, and the COVID-19 vaccines are no different. As with any medical procedure, there are potential drawbacks to using them, but we know from massive pieces of scientific research that the COVID-19 vaccine

SpaceX was down to its last rocket, which was flying aboard a C-17 jet over the Pacific. When it began to crumple, Zach Dunn dove in headfirst.
