A pulsar within a few thousand light-years of Earth could have accelerated electrons and positrons to the highest energies measured by the Hess observatory so far
Some pulsars blow a wind of charged particles into their surroundings, and the magnetic
Charge density waves compete with superconductivity in the ceramic high-temperature superconductors yttrium and neodymium barium cuprates, which lowers the transitional temperature of unconventional superconductors. Researchers around Bernhard Keimer at the Max Planck Institute for Solid State Research investigated how superconducting materials interact with magnetic ones. They also suspect that charge density waves in a superlattice of the cuprate YBCO and the ferromagnetic lanthanum calcium manganate (LCMO) could be the cause of a long-range electron-phonon coupling. The hope that their new insights into charge density waves could improve our understanding of the zero-resistance transport of electricity and could explain an unusual interplay of superconducting and magnetic materials.

It is not always possible to clearly distinguish between what remains free and what is no longer free. This tension is illustrated by the feeling some people have today that they can no longer express themselves freely—a concern that legal experts argue is unfounded. Social media, which is supposed to be open to everyone and everything, often only creates an illusion of freedom. In Russia, spaces for free expression have become scarce, prompting artists to seek them out in creative ways. Once freedom and democracy are restricted or lost in a society, they are not easily restored.
