Scientists Abuzz Over Controversial Rumor that God Particle Has Been Detected 22 April 2011 Time: 05:37 PM ET The leaked note suggests that the LHC's ATLAS particle-detection experiment may have picked up a signature of the elusive Higgs. The signal is consistent, in mass and other characteristics, with what the Higgs is expected to produce, according to the note. However, some other aspects of the signal don't match predictions. "Its production rate is much higher than that expected for the Higgs boson in the Standard Model," Stone told SPACE.com in an email interview. So the signal may be evidence of some other particle, Stone added, "which in some sense would be even more interesting, or it could be the result of new physics beyond the Standard Model." www.livescience.com/13853-higgs-boson-signal-lhc-cern.html

The (Simple) Physics of the ‘God Particle’ July 21, 2010 The other two forces are a little less familiar. They are called the Strong nuclear force, and the Weak nuclear force. These two are basically what holds the nucleus of the atom together, and make it behave the way it does. So what does this have to do with anything? Well remember bosons are messenger particles. The photon carries the electromagnetic force “message”. The other forces in nature have bosons as well that carry their “messages”. Gravity has the “graviton” (which hasn’t been observed yet but we think its out there). The strong nuclear force has the “Gluon” (because it ‘glues’ the nucleus together). And the weak nuclear force has the “W” boson (it doesn”t get a cool name because its not cool). aquantumofknowledge.wordpress.com/2010/07/21/the-simple-physics-of-the-god-particle/

The Strangest Numbers in String Theory May 4, 2011 A forgotten number system invented in the 19th century may provide the simplest explanation for why our universe could have 10 dimensions Largely neglected since their discovery in 1843, in the past few decades they have assumed a curious importance in string theory. And indeed, if string theory is a correct representation of the universe, they may explain why the universe has the number of dimensions it does. www.scientificamerican.com/article.cfm?id=the-strangest-numbers-in-string-theory

Antimatter 'Trapped' For Over 15 Minutes By CERN Scientists Updated: 06/ 5/11 04:30 PM ET (AP/THE HUFFINGTON POST) GENEVA -- Nuclear scientists announced Sunday they have found a way to "trap" for more than 15 minutes elusive antimatter atoms that used to disappear after a fraction of a second. www.huffingtonpost.com/2011/06/05/antimatter-trap-cern_n_871537.html(don't really see the connection between antimatter and 'first moments of the universe,' but hey.)

A ballooning problem: the great helium shortage - Friday 04 January 2013 - Last year, MEG scanners at the universities of Glasgow, London, Oxford and Cambridge were all affected by shortages of helium. “We increasingly face regular periods of forced shut-down of our multimillion-pound facility because of these difficulties, and we are told the problem will only get worse,” said Mark Stokes, a cognitive neuroscientist at Oxford’s Centre for Human Brain Activity. - Liquid helium is critical for the cooling of infrared detectors, nuclear reactors and the machinery of wind tunnels. It is also a vital ingredient of the space industry: Nasa uses the inert gas to purge potentially explosive fuel from its rockets. - Helium is also critical for the massive magnets used by the Large Hadron Collider at the European Organisation for Nuclear Research (Cern) in Geneva. Serge Claudet, who leads the LHC’s work on cryogenics (the branch of physics dealing with the production and effects of very low temperatures), said Cern’s vast size has helped to insulate it against the recent vagaries of the helium market.
