Physicists just discovered a brand-new particle that appears to be an exotic cousin to the protons and neutrons that make up ...

Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...

It is one of history’s more irritatingly on-brand coincidences that Albert Einstein was born on Pi Day, as though the universe itself decided that if it was going to manufacture the patron saint of ...

Abstract: This letter proposes a low-sidelobe wideband design methodology for leaky-wave antennas based on an improved discrete mutation particle swarm optimization (IMDPSO) algorithm. The approach ...

Mars missions, Dr. Lulu Zhao shows how solar particles threaten our tech, and how AI is learning to forecast them.

Optical trapping is a powerful tool for manipulating microscopic particles, but conventional approaches often suffer from limited trapping range and ...
