Study reveals how swimming speed alters foot vortex dynamics

When humans kick swim through water, vortices form around their legs, generating the force that propels them forward. However, the mechanisms underlying variations in the structure of these vortices with swimming speed remain ...

Quantifying metal strength uncertainty in high-explosives models

For the first time, a team of researchers at Lawrence Livermore National Laboratory (LLNL) quantified and rigorously studied the effect of metal strength on accurately modeling coupled metal/high explosive (HE) experiments, ...

A new feature discovered in radioactive lanthanum isotopes

Researchers at the Accelerator Laboratory of the University of Jyväskylä, Finland, precisely measured atomic masses of radioactive lanthanum isotopes and found an interesting feature in their nuclear binding energies. The ...

New technique to detect dark matter uses atomic clocks and lasers

A team of international researchers has developed an innovative approach to uncover the secrets of dark matter. In a collaboration between the University of Queensland, Australia, and Germany's metrology institute (Physikalisch-Technische ...

Imagining the physics of George R.R. Martin's fictional universe

Many science fiction authors try to incorporate scientific principles into their work, but Ian Tregillis, who is a contributing author of the Wild Cards book series when he's not working as a physicist at Los Alamos National ...

Experiment validates electric ion thruster simulations

Predicting the lifetime of an electric ion thruster is notoriously difficult. You have to account for the chamber wall effects, which are not present in space environments. Researchers within several different aerospace disciplines ...
