How the most precise clock ever could change our view of the cosmos
9 September 2024
Forget atomic clocks. Nuclear clocks, which only drop a second every 300 billion years, can test whether nature's fundamental constants are constant after all

Can we solve quantum theory’s biggest problem by redefining reality?
4 September 2024
With its particles in two places at once, quantum theory strains our common sense notions of how the universe should work. But one group of physicists says we can get reality back if we just redefine its foundations
Quantum holograms can send messages that disappear
30 August 2024
Entangled particles of light can transmit holographic images that can be selectively erased, allowing for secure communications that can also be deleted
Ultracold quantum battery could be charged with quantum tunnelling
30 August 2024
Atoms tunnelling through a quantum battery could charge it and also keep it from losing energy, which could give an advantage over conventional batteries
How strange ice could form in the extremely hot interiors of planets
28 August 2024
In an experiment simulating what happens deep in the interiors of planets, scientists have found that liquid can be compressed into ice crystals – even at extremely high temperatures
Tweezers made of light could illuminate the quantum twin paradox
26 August 2024
A single ytterbium atom, cooled down to extreme temperatures and manipulated with laser beams, could reveal how gravity affects quantum objects
Another blow for dark matter as biggest hunt yet finds nothing
26 August 2024
The hunt for particles of dark matter has been stymied once again, with physicists placing constraints on this mysterious substance that are 5 times tighter than the previous best
We can diagnose an object’s quantumness from the way it radiates heat
26 August 2024
To determine an object’s quantum properties, you may only need to measure how it exchanges heat with its environment, without touching the object itself
Quantum trick lets you cool objects down using nothing at all
21 August 2024
Physicists have demonstrated a bizarre cooling effect by setting up a detector to record the absence of photons in a laser experiment
This antimatter version of an atomic nucleus is the heaviest yet
21 August 2024
Smashing gold nuclei together at high speeds billions of times has resulted in 16 particles of antihyperhydrogen-4, a very exotic and heavy form of antimatter
