Scientists have just discovered something new about gold. When extreme crushing pressure is applied quickly, over mere nanoseconds, the element’s atomic structure changes, becoming more similar to metals harder than gold.   It’s the first time this structural state has ever been observed in gold, suggesting properties that could help scientists refine their understanding of

Hidden underneath the Naryn-Kala fortress in Derbent, Russia, is a mysterious subterranean vault – a buried structure whose original purpose has been unknown for decades. Now, thanks to clever use of scanning technology, we might finally know what the building is.   Researchers used a nuclear physics technology known as muon radiography. It works by tracking the

In the summer of 1935, the physicists Albert Einstein and Erwin Schrödinger engaged in a rich, multifaceted and sometimes fretful correspondence about the implications of the new theory of quantum mechanics.   The focus of their worry was what Schrödinger later dubbed entanglement: the inability to describe two quantum systems or particles independently, after they

Using a new technique, scientists have performed the world’s smallest magnetic resonance imaging to capture the magnetic fields of single atoms. It’s an incredible breakthrough that could improve quantum research, as well as our understanding of the Universe on subatomic scales.   “I am very excited about these results,” said physicist Andreas Heinrich of the

For the first time, scientists have clearly linked together two types of gamma-ray phenomena in thunderclouds, suggesting that weak bursts of gamma-ray activity might precede lightning flashes in certain conditions.   The two phenomena in question are weak emissions called gamma-ray glows, which last about a minute, and much shorter and more intense terrestrial gamma-ray

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. Now, 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

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
