Physicists working on a type of fusion reactor called a stellarator are getting closer to actually harnessing the power of nuclear fusion.

Polyfluoroalkyl and perfluoroalkyl substances (PFAS) are known as ‘forever chemicals’ because they don’t naturally break down in the environment. Now a new study reveals the increasing pace of Arctic ice melt is leaking more of these chemicals into the environment.

‘Magic angle’ twisted trilayer graphene doesn’t only have an impressively exotic name, it might be a particularly rare type of superconductor, according to new research – one that could be useful everywhere from medical equipment to quantum computers.

Artificial intelligence (AI) is proving very adept at certain tasks – like inventing human faces that don’t actually exist, or winning games of poker – but these networks still struggle when it comes to something humans do naturally: imagine.

A new set of equations can precisely describe the reflections of the Universe that appear in the warped light around a black hole.

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes.

In the yawning vacuum of intergalactic space, something large is lurking.

Methane is an organic molecule that hangs around in Earth’s atmosphere and is mostly produced by living organisms, most notoriously by farting cows. Its detection on Mars, on the other hand, has been a weird mystery for planetary scientists.

Ironically, pyrite crystals can contain small amounts of real gold, although it is notoriously hard to extract.

Life currently has a sample size of just one. Without an alien or two to expand the boundaries of biology, Earth’s evolutionary history sets the limits on whether we can expect other planets to spawn complex critters like, well, us.
