A kernel of promise in popcorn-powered robots

Public Release: 2-Aug-2018   Cornell University ITHACA, N.Y. – Cornell University researchers have discovered how to power simple robots with a novel substance that, when heated, can expand more than 10 times in size, change its viscosity by a factor of 10 and transition from regular to highly irregular granules with surprising force. You can…

‘Strange metals’ just got stranger

Public Release: 2-Aug-2018 A material already known for its unique behavior is found to carry current in a way never before observed Florida State University TALLAHASSEE, Fla. — Scientists at the Florida State University-headquartered National High Magnetic Field Laboratory have discovered a behavior in materials called cuprates that suggests they carry current in a way…

Study reveals the Great Pyramid of Giza can focus electromagnetic energy

Public Release: 30-Jul-2018 Scientists created a model of the pyramid resonant electromagnetic response ITMO University An international research group applied methods of theoretical physics to investigate the electromagnetic response of the Great Pyramid to radio waves. Scientists predicted that under resonance conditions the pyramid can concentrate electromagnetic energy in its internal chambers and under the…
