Cool electron acceleration
Physicists from the Max-Planck-Institute of Quantum Optics produced electron pulses from a laser accelerator whose individual particles all have nearly the same, tuneable energy.
Researchers seek to determine impacts of differential speed limits on state freeways
Years of research have produced mixed views on whether different freeway speed limits for cars and trucks make roads safer, but Wayne State University researchers are taking a comprehensive approach to answering that question ...
Material low-temperature properties can be predicted from its symmetry
A sphere looks the same no matter how it is rotated. Squash it on one side, however, and this symmetry is broken. A similar change from a high-symmetry state to a low-symmetry state defines many phase transitions ...
