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

Well, those crazy chemistry cats have done it. Nearly 200 years after the molecule was discovered by Michael Faraday, researchers have finally revealed the complex electronic structure of benzene.   This not only settles a debate that has been raging since the 1930s, this step has important implications for the future development of opto-electronic materials,

Scientists have used super high-speed cameras to capture the moment liquid droplets combine together, providing a unique, preternatural glimpse of fluid dynamics the human eye can’t observe on its own.   Using an experimental setup involving two synchronised high-speed cameras – one shooting from the side, and the other looking upwards (courtesy of a mirror

Scientists have managed to get two quantum memories entangled over 50 kilometres (31 miles) of fibre optic cables, almost 40 times the previous record. This achievement makes the idea of a super-fast, super-secure quantum internet a much more plausible one.   Quantum communication relies on quantum entanglement, or what Einstein called ‘spooky action at a distance’:

Nothing lasts forever. Humans, planets, stars, galaxies, maybe even the Universe itself, everything has an expiration date. But things in the quantum realm don’t always follow the rules. Scientists have found that quasiparticles in quantum systems could be effectively immortal.   That doesn’t mean they don’t decay, which is reassuring. But once these quasiparticles have

As 2019 winds to a close, the journey towards fully realised quantum computing continues: physicists have been able to demonstrate quantum teleportation between two computer chips for the first time.   Put simply, this breakthrough means that information was passed between the chips not by physical electronic connections, but through quantum entanglement – by linking

A unique material that appears to decouple an object’s temperature from the amount of thermal radiation it produces could provide a new way of hiding from infrared cameras (not to mention bloodthirsty aliens equipped with infrared vision).   Thermal radiation is emitted by basically everything with a temperature above absolute zero, and the hotter things
