A new chip design includes 41 vertical layers of semiconductor and insulator materials, which allow it to outrun the limits of miniaturisation

Mathematicians thought that they understood how rotation works, but now a new proof has revealed a surprising twist that makes it possible to reset even a complex sequence of motion

Claims that one quantum computer is better than another rest on terms like quantum advantage or quantum supremacy, fault-tolerance or qubits with better coherence – what does it all mean? Karmela Padavic-Callaghan sifts through the noise

The strong nuclear force may abruptly loosen its grip on the fundamental particles that make up matter at a special “critical point” – researchers are now getting a clearer picture of when that point is reached

Short pulses of light that impart rotation on a material's atoms can be used to switch a property called ferroaxiality, which could let us build very stable and efficient memory devices

The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test the boundaries of physics

Mixing nanoparticles into some common plastics made them harder to break and possibly easier to process, pointing towards a way to make better materials or packaging

An array of 6100 ultracold caesium atoms controlled by lasers is the largest collection of qubits ever assembled, and researchers hope they can soon turn it into the world's most advanced quantum computer

Mapping the structure of the brain doesn't fully explain its function

Particles similar to axions, the leading candidate for dark matter that has long eluded detection, may have already been created in particle colliders – and remained hidden in the data
