Lab study suggests longer waves fracture floating ice sheets at lower stress
When waves are moving across ice-covered seas, they can cause sheets of ice to bend and ultimately break. Understanding the processes underlying these wave-induced ice fractures and predicting when they will occur could help ...
Beamline measurements of unstable ruthenium nuclei confirm advanced nuclear models
A novel apparatus at the U.S. Department of Energy's (DOE) Argonne National Laboratory has made extremely precise measurements of unstable ruthenium nuclei. The measurements are a significant milestone in nuclear physics ...

Gravitational wave signal tests Einstein's theory of general relativity
For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers an opportunity to test ...

Measuring the quantum extent of a single molecule confined to a nanodroplet
There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability density of the system ...
The infant universe's 'primordial soup' was actually soupy, study finds
In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles zinged around at light speed, creating a "quark-gluon plasma" that lasted for only a few millionths ...
