Building Bridges and Ladders in Astrophysics: Theory and Experiment Inform the Equation of State
Researchers are combining experimental, theoretical, and observational data on neutron stars to constrain the equation of state (EOS) and to glean the composition of their interiors. Different techniques probe the EOS at different densities, thereby creating a "density ladder" that aims to connect the various rungs. The findings indicate a possible phase transition in the interior of neutron stars.

In new research published in Nature Communications, University of Sussex scientists demonstrate how a highly conductive paint coating that they have developed mimics the network spread of a virus through a process called 'explosive percolation' - a mathematical process which can also be applied to population growth, financial systems and computer networks, but which has not been seen before in materials systems.
Decoding the Proton's Response to an External Electromagnetic Field
The proton is the only composite building block of matter that is stable in nature, making its properties key to understanding the formation of matter.

The results reveal a puzzling new structure - a bump in the polarizability that nuclear theory cannot explain.
