Neutrinos do not go faster than light, according to fresh measurements of a test last year that had suggested the particles broke the Universe's speed limit, CERN said on Friday.

(PhysOrg.com) -- Just as firemen use different methods to narrow the location of a person trapped in a building, scientists employ two techniques to find the hiding place of the theorized Higgs particle: direct searches for Higgs interactions and precision measurements of other particles and forces.

While physicists at the Large Hadron Collider smash together thousands of protons and other particles to see what matter is made of, they're never going to hurl electrons at each other. No matter how high the energy, the little negative particles won't break apart.

(PhysOrg.com) -- Neutrons, the particles that along with protons, exist in the nuclei of atoms (except for hydrogen) have been intensely studied ever since their discovery in the 1930’s. And while many interesting developments have occurred as a result (fission reactions, etc) physicists have continued to be frustrated in their attempts to get a closer look at them, due to their not having an electric charge which could be used to hold them in place.

What is common to blood, ink and gruel? They are all liquids in which tiny particles are suspended – so called “colloids”

Professor Jeremy O'Brien, Director of the University of Bristol's Centre for Quantum Photonics, and his Japanese colleagues have demonstrated a quantum logic gate acting on four particles of light -- photons. The researchers believe their device could provide important routes to new quantum technologies, including secure communication, precision measurement, and ultimately a quantum computer -- a powerful type of computer that uses quantum bits (qubits) rather than the conventional bits used in today's computers.

By shooting a beam of neutrinos through a small slice of the Earth under Japan, physicists say they've caught the particles changing their stripes in new ways. These observations may one day help explain why the universe is made of matter rather than anti-matter.

By Eugenie Samuel Reich of Nature magazine Research groups at the Tevatron, the proton-antiproton collider at Fermilab in Batavia, Illinois, have reached starkly different conclusions about a possible sighting of new particles beyond what is expected under the standard model of particle physics. In April, researchers on the Collider Detector at Fermilab (CDF) experiment reported tentative evidence that particles not predicted by the standard model had surfaced in collisions that produced a W boson--a particle of the weak nuclear force--and jets of other particles.

When someone divides a complex phenomenon into two basic categories, he invariably oversimplifies and distorts reality.
