How Maxwell’s Demon Continues to Startle Scientists
The thorny thought experiment has been turned into a real experiment — one that physicists use to probe the physics of information. […]
For The First Time, Scientists Have Performed Atom Interferometry in Space
To make some of the most precise measurements we can of the world around us, scientists tend to go small – right down to the atomic scale, using a technique called atom interferometry. […]
Nature’s most magnetic objects, ripped apart in starquakes, can unleash powerful flashes of light
On 15 April 2020, a wave of gamma rays, nature’s most powerful kind of light, washed across the Solar System like a storm front. First contact came above Mars, where photons at energies comparable to the radiation from a nuclear […]
¿Cómo volarían un hipogrifo y otros animales fantásticos?
Un paleontólogo y una ilustradora nos muestran cómo serían en la realidad las criaturas mitológicas, si se ajustaran a las reglas de la biomecánica. […]
Quantum computing’s reproducibility crisis: Majorana fermions
The controversy over Majorana particles is eroding confidence in the field. More accountability and openness are needed — from authors, reviewers and journal editors. […]
Los electrones del grafeno se «congelan» con el calor
Los electrones de un material suelen moverse más cuanto mayor es la temperatura, pero en las bicapas de grafeno giradas ocurre justo lo contrario. […]
Is the Standard Model of Physics Now Broken?
The discrepancy between the theoretical prediction and the experimentally determined value of the muon’s magnetic moment has become slightly stronger with a new result from Fermilab. But what does it mean? […]
Particle mystery deepens, as physicists confirm that the muon is more magnetic than predicted
A potential chink in physicists’ understanding of fundamental particles and forces now looks more real. New measurements confirm a fleeting subatomic particle called the muon may be ever so slightly more magnetic than theory predicts, a team of more than […]
Cómo conducir la nanoluz por direcciones ‘prohibidas’
Científicos de la Universidad de Oviedo, el Donostia International Physics Center y otros centros internacionales han conseguido guiar la luz a lo largo de direcciones por las que hasta ahora no se podía en un material de espesor nanométrico. El […]
Long-awaited muon physics experiment nears moment of truth
A result that has been 20 years in the making could reveal the existence of new particles, and upend fundamental physics. […]
