Operators of the world's largest atom smasher on Friday ramped up their massive machine to three times the energy ever previously achieved, in the run-up to experiments probing the secrets of the universe. The European Organization for Nuclear Research, or CERN, said beams of protons circulated at 3.5 trillion electron volts in both directions around the 27-kilometer (17-mile) tunnel housing the Large Hadron Collider under the Swiss-French border at Geneva. The next major development is expected in a few days when CERN starts colliding the beams in a new round of research to examine the tiniest particles and forces within...
GENEVA – Operators of the world's largest atom smasher on Friday ramped up their massive machine to three times the energy ever previously achieved, in the run-up to experiments probing the secrets of the universe.

German woman has failed in a bid to force her country's government to halt experiments at the world's largest atom smasher which she feared would lead to the Earth's destruction. The country's highest court said that the woman — whom it didn't identify — had failed to demonstrate any connection between experiments at the CERN collider outside Geneva and the apocalypse. The Federal Constitutional Court in the western Germany city of Karlsruhe threw out the woman's appeal because she was "unable to give a coherent account of how her fears would come about." "The overwhelming scientific opinion is that the...
“(…) the spread of secondary and latterly tertiary education has created a large population of people, often with well-developed literary and scholarly tastes, who have been educated far beyond their capacity to undertake analytical thought.” — P.B. Medawar So what’s next? A series of essays by Sarah Palin about the Large Hadron Collider and the mysteries of dark matter? An MIT lecture series by Rush Limbaugh regarding the thermodynamics of black holes? A Festschrift of Sean Hannity’s scholarly articles on plate tectonics and volcano formation? Glenn Beck performing live heart-lung transplants on Fox News? Everybody understands that these things couldn’t...
Large Hadron Collider physicists claim energy world record HEREScientists claimed a world record by crashing particles together at the highest energy achieved in a laboratory. Physicists at the Cern nuclear research organisation near Geneva working on the Large Hadron Collider recorded head-on collisions between beams of protons at an energy of 2.36 trillion electron volts. The machine is designed to recreate the conditions in the moments after the big bang. Scientists hope it will help them to identify the Higgs boson, which gives other particles mass, and reveal the nature of dark matter, the invisible substance that clusters around galaxies....
Scientists working at the European Organization for Nuclear Research (Cern), hailed the development as a "great achievement" and a major step towards mimicking the conditions that followed the Big Bang to unlock the secrets of the universe. The low-energy collisions came unexpectedly after researchers managed for the first time to circulate two beams around the 27-kilometre (16.8 mile) tunnel 100m beneath the Franco-Swiss border for the first time on Monday. After 14 months of repairs, the giant machine was restarted on Friday evening and the first beam started circulating in a clockwise direction around the tunnel about 10pm. By Monday,...
Scientists have repaired the world's largest atom smasher and plan by this weekend to restart the fault-ridden Large Hadron Collider. The 'Big Bang' machine was launched with great fanfare last year before its spectacular failure from a bad electrical connection. This time the European Organization for Nuclear Research, known as CERN, is taking a cautious approach with the super-sophisticated equipment, said James Gillies, a spokesman. It cost about $10 billion, with contributions from many governments and universities around the world. Scientists expect to send beams of protons around the 27-kilometer (17-mile) circular tunnel housing the Large Hadron Collider, or LHC,...
Amidst much furor, French anti-terrorism judge Christophe Tessier announced that year-old Algerian-French scientist Dr. Adlene Hicheur had been brought up on charges of “association with terrorists” on October 12. Allegedly in contact with al-Qaeda’s North African affiliate, al-Qaeda in the Islamic Maghreb (AQIM), Dr. Hicheur was arrested with his 25-year old brother (later released) in Vienne, France on October 8 after an 18-month investigation headed by France’s internal security service, the Direction centrale du renseignement intérieur (Central Directorate of Interior Intelligence - DCRI) (Le Monde, October 14).

The huge particle accelerator successfully powered some protons and lead ions around short sections of its 17-mile ring on Friday, and everything seemed to be working correctly. Engineers and scientists have been warily putting it through its paces for the first time since its catastrophic breakdown, or “quench”, which happened when two of the LHC’s huge superconducting magnets suffered a short circuit within hours of it powering up. cross-section of the ion beam flowing through the LHC, just before the ALICE detector The problem ripped the two magnets from their moorings and caused the loss of over a ton of...
