Harnessing laser light's ability to gently push and pull microscopic particles, researchers have created the fiber-optic equivalent of the world's smallest wrench. This virtual tool can precisely twist and turn the tiniest ...

(Phys.org)—Physicists working at the Institute for Quantum Electronics in Switzerland have succeeded in building an apparatus that has allowed for the observation of the drop of resistance in the flow of a superfluid Fermi ...
Picture two charged particles in a vacuum. Thanks to laws of elementary electrostatics, we can easily calculate the force these particles exert upon one another, and therefore predict their movements.

(Phys.org)—Prominent physicist Jacob D. Bekenstein, of the Hebrew University of Jerusalem, has proposed a simple experiment in a paper he's uploaded to the preprint server arXiv, that he says could be used to measure quantum ...
The search for a mysterious subatomic particle can certainly involve some enormous tools, not to mention a multitude of scientists. The effort to find the elusive "Higgs boson" includes over 5,800 scientists from 56 countries! ...

What is light made of: waves or particles? This basic question has fascinated physicists since the early days of science. Quantum mechanics predicts that photons, particles of light, are both particles and waves simultaneously. ...

Scientists have created new kinds of particles, 1/100th the diameter of a human hair, that spontaneously assemble themselves into structures resembling molecules made from atoms. These new particles come together, or "self-assemble," ...

All of the atoms in our bodies are made of electrons, protons and neutrons, and the protons and neutrons can be further broken down into quarks. Fundamentally, then, we are made of only two types of particles: electrons and ...
