Nima Arkani-Hamed is championing a campaign to build the world's largest particle collider - "Two years ago, he agreed to become the inaugural director of the new Center for Future High Energy Physics in Beijing. He has since visited China 18 times, campaigning for the construction of a machine of unprecedented scale: a circular particle collider up to 60 miles in circumference, or nearly four times as big around as Europe's Large Hadron Collider (LHC). Nicknamed the 'Great Collider', and estimated to cost roughly $10 billion over 30 years, it would succeed the LHC as the new center of the physics universe. According to Arkani-Hamed and those who agree with him, this 100-trillion-electron-volt (TeV) collider would slam subatomic particles together hard enough to either find the particles that the LHC could not muster or rule them out, rescuing or killing the naturalness principle and propelling physicists toward one of two radically different pictures: that of a knowable universe, or an unknowable multiverse."

What happens if you get hit by the main beam of a particle accelerator like the LHC?. "Well, fortunately (unfortunately?) we don’t have to guess, as this exact scenario actually happened to Anatoli Bugorski, a Russian scientist, way back in 1978."

"We have entered the new millennium and yet we still have no idea what 95% of the universe is made of." The Large Underground Xenon experiment has failed to see a single particle of Dark Matter. Will the Lux Zeplin have better luck?
Decades of confounding experiments have physicists considering a startling possibility: The universe might not make sense. For you Saturday night science read, a very interesting science article, one of many on the Simons Foundation web site

Drawings of the elements of CMS detector, in the style of Leonardo da Vinci "Sergio Cittolin is first and foremost a physicist in search of answers to the mysteries of the universe. Yet he also has an artistic bent, and his talent for drawing has woven itself nicely into his 30 years of work at CERN. The result is a collection of Leonardo da Vinci-style illustrations that brighten CERN hallways, a book, and the covers of a number of technical documents." (via)
Higgs Boson explained - via animation or, by click by click comic version. A brief talk about the mysterious Higgs Boson and the LHC search for it, given by particle physicist Daniel Whiteson
We’re on the verge of two world-changing antimatter discoveries
While the Large Hadron Collider is looking for the Higgs boson, we're on the verge of two huge antimatter-related breakthroughs. One could finally solve the universe's oldest mystery, while the other could reveal strange new particles that are perfect for quantum computers.
What does a Higgsless universe mean for science? The Higgs Boson is quite important to the standard model of physics. If it exists, it plays a major role in explaining how particles acquire mass. There’s a distinct possibility that the Higgs Boson may not even exist. Stephen Hawking made a famous bet that the Large Hadron Collider (LHC) wouldn't find it. So far both the LHC and Tevatron, another massive particle accelerators have both searched much of the energy ranges we expected to find the Higgs with no luck. So, then, what does it mean if we don’t find the Higgs at all?
The CDF collaboration at Fermilab is set to announce evidence for non-Standard Model physics today. The experiment at the Tevatron particle collider has released a paper on the Arxiv stating it has found evidence for a potential new particle that isn't the Higgs boson. A live stream announcing the results will begin at 4pm Central time (21:00 GMT). [more inside]

Several physicists weigh in on what would happen if you were to place your hand in the proton stream of the Large Hadron Collider at CERN. There's not a definite answer...the responses range from "nothing" to "you'd die for sure, instantly". [more inside]
The Large Hadron Collider is attempting to collide protons at 14 TeV today, and they're livestreaming and tweeting about it. They've had some delays, and mostly you hear people milling about, (press conference from Japan right now) but it's ramping up as we speak, so go check it out! If it's not a dud, it could be historical.
The Genesis 2.0 Project The L.H.C. is not merely the world’s largest particle accelerator but the largest machine ever built. At the center of just one of the four main experimental stations installed around its circumference, and not even the biggest of the four, is a magnet that generates a magnetic field 100,000 times as strong as Earth’s. And because the super-conducting, super-colliding guts of the collider must be cooled by 120 tons of liquid helium, inside the machine it’s one degree colder than outer space, thus making the L.H.C. the coldest place in the universe.
CERN has successfully circulated beams in the Large Hadron Collider. This news was announced via Twitter, where they will be accepting questions for an upcoming press conference; in the meantime, check out explanatory videos on their YouTube channel, some lively podcasts, or an overview of particle physics on their website. The home of the Web has done a pretty good job keeping up with technology. (previously)

BBC: Hadron Collider forced to halt. An underground tunnel fault released one ton of liquid helium, which had been acting as coolant, into the tunnels of the Large Hadron Collider, causing 100 supercooled magnets to heat up by an extra 100°C and then fail. Vacuum was lost as well.
The ALICE Collaboration is building a dedicated heavy-ion detector to exploit the unique physics potential of nucleus-nucleus interactions at LHC energies. The aim is to study the physics of strongly interacting matter at extreme energy densities, where the formation of a new phase of matter, the quark-gluon plasma, is expected. This website aims both at introducing non-initiates to the field of physics covered by ALICE and at providing regular information on the evolution of the experiment, with detailed reports of its results and analysis.
Hackers attack Large Hadron Collider Hackers have mounted an attack on the Large Hadron Collider, raising concerns about the security of the biggest experiment in the world as it passes an important new milestone.
LHC Webcams. There's been a lot of LHC news lately but a less-publicized series of Compact Muon Solenoid proton collision tests is scheduled for today, and CERN has been kind enough to set up a live streaming webcam to watch the CMS in action. (There's also a view of the parking lot but I think that's more so underground-bunkered LHC staff can see the weather.) It's fairly dull viewing but if you're interested in the science of it all, it's great nerdy fun. Maybe you'll even see a black hole or two. ;)
In a scant few hours, scientists will make the first attempt to circulate a beam in the Large Hadron Collider. Terrified of nothing, a few deeply misguided morons have sent death threats to the CERN team, probably because of Faith-Based Science. [more inside]
