Antineutrinos, the antimatter counterpart of neutrinos, have an almost non-existent mass and charge, and almost never interact with other particles, which makes them particularly difficult to detect. Physicists have been ...
Could a laser send a spacecraft to Mars? That's a proposed mission from a group at McGill University, designed to meet a solicitation from NASA. The laser, a 10-meter wide array on Earth, would heat hydrogen plasma in a chamber ...
Tokamaks, devices that use magnetic fields to confine plasma into torus-shaped chamber, could play a crucial role in the development of highly performing nuclear fusion reactors. The ITER tokamak, which is set to be the largest ...
Research published in the journal Physical Review Letters conducted by an international team of scientists including Joshua Klein, the Edmund J. and Louise W. Kahn Term Professor in the School of Arts & Sciences, has resulted ...
