They're incredible. Amazing. Magical. But perhaps the most fantastic thing about lucid dreams – in which the dreamer becomes aware they're dreaming – is how realistic they seem.

Caffeine is our favourite drug. But if we miss out on our fix, it can be a real headache, in more ways than one.

The gene-editing technology CRISPR is already making a huge difference across many scientific fields, but its importance could be about to grow even further – scientists have discovered a new technique that can leave out particular sections of a gene, essentially…

The breakdown of some of the oldest and thickest sea ice in the Arctic has occurred for the first time in recorded history. Not once, but twice this year, the breaking ice has opened waters north of Greenland that are usually frozen even in summer.

The Milky Way is a zombie. No, not really, it doesn't go around eating other galaxies' brains. But it did "die" once, before flaring back to life. That's what a Japanese scientist has ascertained after peering into the chemical compositions of our

Researchers have identified a brand new 'micro-organ' inside the immune system of mice and humans – the first discovery of its kind for decades – and it could put scientists on the path to developing more effective vaccines in the future.

As you may know from scrubbing the kitchen, getting a surface well and truly clean is a real challenge – and even more so for scientists working at microscopic levels.

Physicists have come up with what they claim is a mathematical model of a theoretical "time machine" - a box that can move backwards and forwards through time and space.

Scientists are usually a rather cheery bunch. But every now and then, they have a habit of wondering how the Universe might cave in and destroy us in the blink of an eye. Take physicists Frans Pretorius from Princeton University and William East from the…

A global dust storm on Mars is threatening the future of NASA's Opportunity rover, the longest-lived robot on that planet.

Around 252 million years ago, the Earth changed drastically and catastrophically. Massive, ongoing volcanic activity in Siberia wrapped the planet in a thick shroud of ash for almost a million years, killing off most of the life that was around at

On August 21 last year, the US came to a standstill to watch the incredibly rare alignment of the Moon sliding in front of the Sun, completely blocking its rays.

It's compact, bushy, and responsible for telling other neurons to shush. Beyond that, nobody is entirely sure what a newly discovered variety of brain cell called a rosehip neuron does.

During the peak of the last glacial period, some 25,000 years ago, the population of prehistoric cave bears (Ursus spelaeus complex) dwindled to a trickle. And then, there were none.

Particle accelerators can lead to major breakthroughs in our understanding of the universe, and now, we may have a better way to create them.

It's no secret America is hurting right now. Life expectancy is in decline, fuelled by a deadly national addiction to painkillers that knows almost no bounds.

An international group of scientists from Politecnico di Torino (Italy) and NUST MISIS has developed a model of a new metamaterial, which…

What's up with the Sun? As we've said previous, what the Sun isn't doing is the big news of 2018 in solar astronomy.

Saturn has been out there getting up to its old tricks again: looking really spectacular and being super interesting. This time, it's in a series of photos taken by the Hubble Space Telescope, showing the planet's breathtaking auroras.

Black holes are famous for tearing apart and devouring stars. But new simulations suggest that, in the very final moments, black holes can actually bring stars back to life.

For the first time, scientists have figured out how to accelerate electrons using protons passing through plasma.
