The existence of time crystals – a particularly fascinating state of matter – was only confirmed a few short years ago, but physicists have already made a pretty major breakthrough: they have induced and observed an interaction between two time crystals.   In a helium-3 superfluid, two time crystals exchanged quasiparticles without disrupting their coherence;

When an enormous explosion created a mushroom cloud over Beirut, killing dozens of people and injuring thousands more, online commentators and conspiracy theorists quickly jumped to a frightening claim: A nuclear bomb had gone off in Lebanon’s capital city.   But as state officials say, and contrary to those fast-spreading rumours, the explosion was almost certainly not

Longer-lasting, more efficient batteries would be a boost for everything from smartphones to electric vehicles, and scientists have now made an unexpected discovery that could help develop next-gen battery tech, as well as faster catalysts and other advanced materials.   An analysis of the very earliest stages of lithium battery charging – known as nucleation

Nearly a century after experiments confirmed that atoms, matter’s smallest building blocks, have ethereal, wave-like characteristics, physicists have just found a new way to show how mammoth-sized molecules ripple with the same uncertainty.   Researchers from the University of Vienna and the University of Duisburg-Essen, Germany, put a new spin on a classic experiment to

In the strange field of quantum physics, quantum entanglement – what Einstein called “spooky action at a distance” – stands out as one of the most intriguing phenomena. And now scientists just managed to successfully demonstrate it again, this time onboard a CubeSat satellite orbiting Earth.   Quantum entanglement is where two particles become inextricably

The famous cat-in-a-box thought experiment by Austrian physicist Erwin Schrödinger is an illustration of one of the defining characteristics of quantum mechanics – the unpredictable behaviour of particles at the quantum level.   It makes working with quantum systems incredibly difficult; but what if we could make quantum predictions? A team of physicists believes it’s

Scientists have found evidence that a fundamental physical constant used to measure electromagnetism between charged particles can in fact be rather inconstant, according to measurements taken from a quasar some 13 billion light-years away.   Electromagnetism is one of the four fundamental forces that knit everything in our Universe together, alongside gravity, weak nuclear force,

Eight years after he first shared it online, Kyoto University mathematician Shinichi Mochizuki’s controversial, 600-page proof for a profound mathematical conjecture has been approved for publication in an academic journal.   But there’s a twist: academic mathematicians around the world didn’t believe that Mochizuki solved the problem, known as the “abc conjecture,” back then, Nature
