It appears that the faster-than-light neutrino results, announced last September by the OPERA collaboration in Italy, was due to a mistake after all. A bad connection between a GPS unit and a computer may be to blame.

Physicists had detected neutrinos travelling from the CERN laboratory in Geneva to the Gran Sasso laboratory near L'Aquila that appeared to make the trip in about 60 nanoseconds less than light speed. Many other physicists suspected that the result was due to some kind of error, given that it seems at odds with Einstein's special theory of relativity, which says nothing can travel faster than the speed of light. That theory has been vindicated by many experiments over the decades.

<![CDATA[On Discovering Life]]> http://seedmagazine.com/content/article/on_discovering_life/

There is an aspect of life sciences that has been largely absent: the confrontation of fundamental questions of biology much as particle accelerators grapple with fundamental questions of physics. The roll call of early pioneers and prospectors is notable, but short. Fortunately, increasing numbers of researchers are now re-entering this fertile frontier.

The open secret of this emerging frontier is that we do not have a fundamental definition or understanding of life. Similarly, we do not understand life’s origins, how life emerges from chemistry. We do know that the chemistry of life on Earth, or “Terran” biochemistry for short, is rather restrictive in its molecular permutations. Unnecessarily so, it seems, given the enormous choice of good options provided by chemistry for building biological bodies and functions. However, we do not know whether nature or nurture is the reason.

<![CDATA[CERN Podcast | Chris Morris]]> http://www.cernpodcast.com/?p=43

Chris Morris is considered to be one of the greatest satirists ever and has been responsible for some of the most controversial, and let’s face it funny, programmes on television. In the UK, comedy writers and performers ranked him number 11 out of the 50 greatest comedy acts ever, above people including Bill Hicks, Peter Sellars and Eddie Izzard.

Apart from being a comedy great, he’s an incredibly interesting guy. He’s performed with Peter Cook, Stereolab used his sketches as lyrics on one of their albums, he won a BAFTA for his first short film and, for ‘Brass Eye’, he tricked a British politician into asking questions in Parliament about a made-up drug called ‘cake’ (which still remains in the public record).

Oh, and he’s also really into science.

Brian and Chris have been friends for several years now. When they get together, conversation tends to start on politics (Brian’s favoured topic of conversation) and move swiftly onto what’s being done at CERN (Chris’s favoured topic of

<![CDATA[Kurt Andersen on the Large Hadron Collider]]> http://www.vanityfair.com/culture/features/2010/01/hadron-collider-201001?printable=true

Among the defining attributes of now are ever tinier gadgets, ever shorter attention spans, and the privileging of marketplace values above all. Life is manically parceled into financial quarters, three-minute YouTube videos, 140-character tweets. In my pocket is a phone/computer/camera/video recorder/TV/stereo system half the size of a pack of Marlboros. And what about pursuing knowledge purely for its own sake, without any real thought of, um, monetizing it? Cute.

And so in our hyper-capitalist flibbertigibbet day and age, the new Large Hadron Collider, buried about 330 feet beneath the Swiss-French border, near Geneva, is a bizarre outlier.

The L.H.C., which operates under the auspices of the European Organization for Nuclear Research, known by its French acronym, cern, is an almost unimaginably long-term project. It was conceived a quarter-century ago, was given the green light in 1994, and has been under construction for the last 13 years, the product of tens of millions of man-hours. It’s also gargantuan: a circular tunnel 17 miles around, punctuated by shopping-mall-size subterranean caverns and fitted out with more than $9 billion worth of steel and pipe and cable more reminiscent of Jules Verne than Steve Jobs.

The believe-it-or-not superlatives are so extreme and Tom Swiftian they make you smile. 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.

<![CDATA[Spooky Signals from the Future Telling Us to Cancel the LHC!]]> http://blogs.discovermagazine.com/cosmicvariance/2009/10/14/spooky-signals-from-the-future-telling-us-to-cancel-the-lhc/

A recent essay in the New York Times by Dennis Overbye has managed to attract quite a bit of attention around the internets — most of it not very positive. It concerns a recent paper by Holger Nielsen and Masao Ninomiya (and some earlier work) discussing a seemingly crazy-sounding proposal — that we should randomly choose a card from a million-card deck and, on the basis of which card we get, decide whether to go forward with the Large Hadron Collider. Responses have ranged from eye-rolling and heavy sighs to cries of outrage, clutching at pearls, and grim warnings that the postmodernists have finally infiltrated the scientific/journalistic establishment, this could be the straw that breaks the back of the Enlightenment camel, and worse.

Since I am quoted (in a rather non-committal way) in the essay, it’s my responsibility to dig into the papers and report back. And my message is: relax! Western civilization will survive. The theory is undeniably crazy — but not crackpot, which is a d

<![CDATA[The Collider, the Particle and a Theory About Fate]]> http://www.nytimes.com/2009/10/13/science/space/13lhc.html

Dr. Nielsen and Dr. Ninomiya have proposed a kind of test: that CERN engage in a game of chance, a “card-drawing” exercise using perhaps a random-number generator, in order to discern bad luck from the future. If the outcome was sufficiently unlikely, say drawing the one spade in a deck with 100 million hearts, the machine would either not run at all, or only at low energies unlikely to find the Higgs.

Sure, it’s crazy, and CERN should not and is not about to mortgage its investment to a coin toss. The theory was greeted on some blogs with comparisons to Harry Potter. But craziness has a fine history in a physics that talks routinely about cats being dead and alive at the same time and about anti-gravity puffing out the universe.

As Niels Bohr, Dr. Nielsen’s late countryman and one of the founders of quantum theory, once told a colleague: “We are all agreed that your theory is crazy. The question that divides us is whether it is crazy enough to have a chance of being correct.”
