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."

Frank Wilczek: Physics in 100 Years [pdf] - "Here I indulge in wide-ranging speculations on the shape of physics, and technology closely related to physics, over the next one hundred years. Themes include the many faces of unification, the re-imagining of quantum theory, and new forms of engineering on small, intermediate, and large scales." [more inside]
Physics World has reported that "US physicist Val Fitch, who shared the 1980 Nobel Prize for Physics with James Cronin, died on 5 February at the age of 91. Fitch and Cronin were awarded the prize for the discovery in 1964 that subatomic particles called K-mesons violate a fundamental law in physics known as CP symmetry, allowing physicists to make an absolute distinction between matter and antimatter." Fitch's passing was noted in Princeton University News, and an extended obituary appeared in the Washington Post.
By making a very precise measurement of the muon g-2 value and comparing the results to its predicted value, researchers at Fermilab hope to uncover evidence of new, undiscovered particles and forces. This continues work done at Brookhaven National Laboratory a decade ago. To do so, Fermilab needs their 50-ft ring magnet and its fragile, precisely assembled superconducting coils. After six months of planning, the magnet was slowly hauled on an eight-axle trailer through the streets of Long Island, loaded onto a barge, and tugged down the Atlantic coast and into the Gulf of Mexico, where it will go up the Tennessee-Tombigbee Waterway to the Mississippi and then through Illinois waterways before it's trucked again through suburban Chicago. Fermilab has a photo and video gallery and is posting updates. [more inside]
"I'm confident that it's a Higgs particle. I don't need to call it Higgs-like any more...I may need to eat my words one day, but I think that's very unlikely.""Cern scientists believe newly discovered particle is the real Higgs boson. Results of analysis at Cern in Switzerland show particle behaves precisely as expected." Previously
Rumor Sweeping World's Science Community that CERN's LHC has Detected the Higgs Boson -The "God Particle"
Rumor Sweeping World's Science Community that CERN's LHC has Detected the Higgs Boson -The "God Particle" The controversial rumor is based on what appears to be a leaked internal note from physicists at CERN's Large Hadron Collider (LHC), a 17-mile-long particle accelerator near Geneva, Switzerland. It's not certain at this point if the memo is authentic, or what the data it refers to might mean — but the note has sent the physics community into full buzz mode.
Many thought the secrets of the universe would be revealed by the LHC in Switzerland, but the lower powered Brookhaven Collider briefly violated the laws of physics recently.
