Plasma physics is the study of a state of matter comprising charged particles. Plasmas are usually created by heating a gas until the electrons become detached from their parent atom or molecule. This ...

Biophysics is the study of physical phenomena and physical processes in living things, on scales spanning molecules, cells, tissues and organisms. Biophysicists use the principles and methods of ...

Transmitting electricity without losing any energy may sound impossible, yet this is precisely the promise of superconductivity. For nearly 40 years, scientists have been working to understand ...

For the first time, Northwestern University physicists have coaxed a single positron—the antimatter counterpart of an electron—into an exquisitely controlled quantum state. Quantum networks, systems ...
