Julian Muñoz has a ‘ruler’ that could size up the early universe
The measurement tool could lay out a distance scale for cosmic dawn —and offer clues to the nature of dark matter.

Physicists split bits of sound using quantum mechanics
New experiments put phonons — the tiniest bits of sound — into quantum mechanical superpositions and show they are as weird as other quantum entities.

One photon is all it takes to kick off photosynthesis
A single particle of light is the spark that begins the process of turning light to chemical energy in photosynthetic bacteria, a new study confirms.

The Parker Solar Probe may have spotted the origin of high-speed solar winds
Kinks in the magnetic fields near the surface of the sun appear to be the cause of fast-moving flows in the solar wind.

Weird black holes may hold secrets of the early universe
Big black holes in little galaxies, rogue black holes and other behemoths could offer clues to cosmic evolution.

Measurements of a key radioactive decay nudge a nuclear clock closer to reality
In a step toward building a nuclear clock, scientists measured light emitted when a special type of thorium nucleus decayed.

Quantum computers braided ‘anyons,’ long-sought quasiparticles with memory
Particle-like quantum states called non-abelian anyons remember being swapped and could be useful for protecting information in quantum computers.

This house was built partly from recycled diapers
Disposable diapers can replace nearly a third of the materials used in load-bearing structures, offering a potential path to more affordable housing.

Jupiter’s lightning bolts contort the same way as Earth’s
Jovian lightning extends in jagged steps as it does on Earth, data from NASA’s Juno spacecraft suggest. The finding might aid the search for life.

Science explains why shouting into the wind seems futile
Sending a sound upwind, against the flow of air, makes the sound louder due to an acoustical effect called convective amplification. Sound sent downwind is quieter.

Black holes resolve paradoxes by destroying quantum states
A classic quantum experiment done near a black hole would create a paradox, physicists report. But not if the black hole collapses quantum states.

These worms can escape tangled blobs in an instant. Here’s how
Tangled masses of California blackworms form over minutes but untangle in tens of milliseconds. Now scientists know how.
