A neutrino mass mismatch could shake cosmology’s foundations
Cosmological data suggest unexpected masses for neutrinos, including the possibility of zero or negative mass.

The Large Hadron Collider exposes quarks’ quantum entanglement
Top quarks and antiquarks produced in the Large Hadron Collider are entangled, a study shows.

How to spot tiny black holes that might pass through the solar system
Flybys of primordial black holes may occur once a decade. Tweaks to the orbits of planets and GPS satellites could give away their presence.
- Quantum Physics
A quantum computer corrected its own errors, improving its calculations
The corrected calculation had an error rate about a tenth of one done without quantum error correction.

50 years ago, some of plastic’s toxic hazards were exposed
Worker exposure to vinyl chloride became tightly regulated after the chemical was linked with liver cancer. Now, its use may be on the chopping block.

A nuclear clock prototype hints at ultraprecise timekeeping
Nuclear clocks could rival atomic clocks and allow for new tests of fundamental physics. A new experiment demonstrates all the ingredients needed.

Mayo is weirdly great for understanding nuclear fusion experiments
Mayonnaise’s texture is perfect for mimicking what a fusion fuel capsule goes through after it’s blasted with lasers.

The possibilities for dark matter have just shrunk — by a lot
The LZ dark matter experiment has ruled out weakly interacting massive particles, or WIMPs, with a wide range of properties.

The world’s fastest microscope makes its debut
Using a laser and an electron beam, the microscope can snap images of moving electrons every 625 quintillionths of a second.
- Climate
Zigzag walls could help buildings beat the heat
A corrugated exterior wall reflects heat to space and absorbs less heat from the ground, keeping it several degrees cooler than a flat wall.
