CERN FAILURE-Fermilab cannot get the magnets right

Plans to begin smashing particles at the Large Hadron Collider (LHC) may be delayed after a magnet failure forced engineers to halt work.
The failure, known as a quench, caused around 100 of the LHC’s super-cooled magnets to heat up by as much as 100C.
The fire brigade were called out after a tonne of [...]

CERN, GLAST, SPACETIME WHAT ARE WE GOING TO DO?

A global network listens for ripples in space–time
Detectors in Europe and the US have linked up for the task of detecting gravitational waves and pinpointing their sources. The first combined data-taking illustrates the power of working together, as Carlo Bradaschia and Riccardo Desalvo explain.

Résumé
Un réseau mondial à l’écoute des vagues de l’espace–temps
Les ondes gravitationnelles sont [...]

BROOKHAVEN RHIC

The physicists have developed a way to measure subtle fluctuations in RHIC’s particle beams as they speed around their 2.4-mile-circumference high-tech racetrack – and send that information ahead to specialized devices that smooth the fluctuations when the beam arrives.

“These corrections help to keep the beams focused and colliding, recreating thousands of times a second the [...]

CERN – EXTRA DIMENSIONS

Ehrenfest’s students, Leiden 1924. Left to right: Gerhard Heinrich Dieke, Samuel Abraham Goudsmit, Jan Tinbergen, Paul Ehrenfest, Ralph Kronig, and Enrico Fermi.
Only 2 years ago, the idea of extra dimensions inhabited a nebulous region somewhere between physics and science fiction
Many physicists had already begun to see the up-and-coming string theory as the next major step [...]
