Using gravitational waves to observe thermal effects in binary neutron star mergers
In a study published in The Astrophysical Journal Letters, researchers examined neutron star mergers using THC_M1, a computer code that simulates neutron star mergers and accounts for the bending of spacetimes, due to the strong gravitational field o.....»»
Frostquakes: A new earthquake risk in the north?
A new study has identified a potentially growing natural hazard in the north: frostquakes. With climate change contributing to many observed changes in weather extremes, such as heavy precipitation and cold waves, these seismic events could become mo.....»»

Collisions change how fast ions surf on plasma waves in fusion experiments and beyond
Just like there are waves in the ocean, waves can also occur in an electrically charged gas called a plasma, made up of electrons and ions. In the ocean, people surf by riding their boards at nearly the same speed as the waves. This matching conditio.....»»
The Universe in a lab: Testing alternate cosmology using a cloud of atoms
