1. The speed of gravity is pretty much identical to the speed of light! This year, for the first time ever, scientists were able to photograph a collision between two neutron stars. By conducting simultaneous optical and gravitational wave observations, they…

The world of science is unpredictable and ever-changing, but as a team that writes about science day in, day out, we can't help but notice certain trends in research. So this year - which also happens to be ScienceAlert's 10th anniversary - we thought we'd…

Imagining the future of humanity, our planet, and everything we hold dear in our corner of the cold dark Universe is typically the domain of science fiction, and we're usually only worried about the next few hundred years at best. But what about thousands…

Black hole scientists sure have been busy. At the end of last year, researchers announced that the powerful winds emanating from supermassive black holes shape entire galaxies.

Humans may possess an inherent ability to detect sick people from subtle visual cues. This skill could act as a behavioural defence against disease by limiting the risk of contamination, according to new research.

Silicon Valley is abuzz about 'Meltdown' and 'Spectre' – new ways for hackers to attack Intel, AMD, and ARM processors that were first discovered by Google last year, and publicly disclosed Wednesday.

It would be no exaggeration to say that we live in an age of renewed space exploration.

We're used to dealing with three physical dimensions and one extra dimension of time as we move through the Universe, but two teams of scientists have shown that a fourth spatial dimension could reach beyond the limits of up and down, left and righ

Scientists have long been intrigued by why people tend to naturally favour the use of one hand over the other. We still don't fully understand what causes people to be left or right handed, but for decades researchers have assumed that the origin l

One Laysan albatross is brazenly defying the norms for her species. Wisdom, the world's oldest known wild bird, has returned to home port and laid an egg - at the magnificent age of 67 years old. It's a feat that gets more impressive every year she does it…

When exposed to weightless conditions, astronauts can really pick up a temperature, new research reveals. This kind of 'space fever' comes on even when the body is at rest, and this strange finding is giving us more insight into how human beings co

Your gut microflora isn't just sitting silently waiting for you to wolf down your next meal – it turns out there's a constant conversation going on between these bacteria and your body's genetic code.

Fast radio bursts (FRBs) are one of our Universe's most confounding mysteries - but astronomers may have just figured out the incredible environment where one of the most famous and well-studied FRBs is coming from.

We're not going to fly through a nebula, not in the lifetimes of anyone alive today. Possibly not ever in anyone's lifetime.

She was flying home from a holiday in Samoa when she saw it through the airplane window: a "peculiar large mass" floating on the ocean, hundreds of kilometres off the north coast of New Zealand.

A study using epilepsy patients undergoing surgery has given neuroscientists an opportunity to track in unprecedented detail the movement of a thought through the human brain, all the way from inspiration to response. The findings confirm the role of the…

If you were awestruck by the New Year's Day super moon, hold onto your pants. On January 31, around midnight, the full moon will not only be super, it will be a blue moon and a blood moon. The blue moon comes as it will be the second full moon in a month.…
