PhysicsTrapping atoms in a laser beam offers a new way to measure gravity
A new type of experiment to measure the strength of Earth’s gravity uses atoms suspended in light rather than free-falling atoms.
-
TechThe first artificial material that follows sunlight may upgrade solar panels
Rows of tiny stemlike rods called SunBOTs orient themselves toward light, optimizing the solar energy that they can harvest.

Quantum PhysicsGoogle officially lays claim to quantum supremacy
The quantum computer Sycamore reportedly performed a calculation that even the most powerful supercomputers available can’t reproduce.
-
PhysicsPhysicists have found quasiparticles that mimic hypothetical dark matter axions
These subatomic particles could make up dark matter in the cosmos. A mathematically similar phenomenon occurs in a solid material.
-
Materials ScienceA new cooling technique relies on untwisting coiled fibers
A “twist fridge” operates via twistocaloric cooling, a technique that generates cooling by unraveling twisted strands.
