This is what it sounds like when protons collide

When you think about it, the particles being slammed into each other at the Large Hadron Collider at the CERN facility in Switzerland are kind of like people in a mosh pit at a rock concert. But that's not the only thing the particle accelerator has in common with music. Apparently, if you take the data coming from one of the LHC's collision chambers and fool with it a bit, you can actually listen to music being made by protons colliding. That's exactly what a new project called the Quantizer has done – and you can listen in.Read More

Weasel takes down Large Hadron Collider

A small furry animal today took on the largest atom smasher ever made, and won. According to internal documents at CERN, the Large Hadron Collider was knocked out of commission at about 5:30 am CEDT when a weasel caused a "severe electrical perturbation" when it stepped on the bare connections of a 66,000 volt transformer. This not only proved instantly fatal to the weasel, but it also short circuited the power system, causing the LHC to execute a fast abort as the sudden power loss created a series of anomalies.Read More

CERN sets new high-energy collision record

The Large Hadron Collider (LHC) recently set a new record, as CERN announced that the world's most powerful accelerator had achieved the highest-energy collisions of heavy atomic nuclei. The Geneva-based laboratory says that on Wednesday at 11:15 am CET, the 27 km (17 mi)-long supercollider fired two counter-circulating beams of lead nuclei at one another and the results were recorded by the ALICE heavy-ion detector.Read More

Meson f0(1710) could be so-called “glueball” particle made purely of nuclear force

Terms to describe the strange world of quantum physics have come to be quite common in our lexicon. Who, for instance, hasn't at least heard of a quark, or a gluon or even Schrodinger's cat? Now there's a new name to remember: "Glueball." A long sought-after exotic particle, and recently claimed to have been detected by researchers at TU Wien, the glueball's strangest characteristic is that it is composed entirely of gluons. In other words, it is a particle created from pure force.Read More

CERN develops miniature linear accelerator for medical use

The Large Hadron Collider (LHC) at CERN is where the miraculous meets the impractical. In addition to probing the secrets of the Universe at the subatomic level, it also has potential for a variety of medical applications. Unfortunately, with a circumference of 27 km (16.7 mi) the LHC is so unwieldy that it would be about as practical as using Big Ben for a wristwatch. In the hopes of creating something a bit more useful for the medical fraternity, CERN engineers have come up with a miniature linear accelerator (mini-Linac) that, at 2 m (6.5 ft) long, is small enough to be set up in hospitals for medical imaging and radiotherapy applications.Read More

Large Hadron Collider limbers up after two-year overhaul

Restarting the world's largest particle accelerator after a two-year overhaul isn't just a matter of throwing a switch and making sure the lights go on. It's an eight-week process of baby steps – one's that involve billions of electron volts. But the Large Hadron Collider (LHC) took a major step forward this week as the CERN team fired up two counter-rotating proton beams that were injected into the LHC using the Super Proton Synchrotron, then accelerated to an energy of 450 GeV each.Read More

Large Hadron Collider back on line

As the saying goes, you can't keep a good particle accelerator down. In Switzerland, CERN has announced that the Large Hadron Collider (LHC) is back online after a major overhaul and refit. This power-up of the most powerful particle accelerator in the world marks the culmination of two years of work and months of testing, resulting in a significant boost in performance for the giant collider's "season 2."

Happy Birthday: The Web turns 25

On March 12, 1989 Tim Berners-Lee, while working as a contractor at the CERN laboratories in Switzerland, submitted Information Management: A Proposal, which sparked the greatest advance in information technology since Gutenberg invented the printing press. At the time, it was just a way for CERN scientists to share data, but a quarter of a century later, it’s grown from a curiosity into a necessity without which our world can no longer function.Read More
