The uncertainties in measuring cosmic expansion

Ninety years after Edwin Hubble discovered the systematic motions of galaxies and George Lemaitre explained them as cosmic expansion from a point using Einstein's equations of relativity, observational cosmology today is ...

Engineers reveal molecular secrets of cephalopod powers

Reflectins, the unique structural proteins that give squids and octopuses the ability to change colors and blend in with their surroundings, are thought to have great potential for innovations in areas as diverse as electronics, ...

Compressive fluctuations heat ions in space plasma

New simulations carried out in part on the ATERUI II supercomputer in Japan have found that the reason ions exist at higher temperatures than electrons in space plasma is because they are better able to absorb energy from ...

Scientists first to simulate a large-scale virus, M13

Atomistic simulations are a powerful tool to study the movement and interactions of atoms and molecules. In many biological processes, large-scale effects, for example, assembly of large viruses to nanoparticles are important. ...
