As the less distracted among you have already figured out, I have permanently moved my blogging activities to www.scientificblogging.com. The reasons for the move are explained here.

Since I know that this site continues to be visited -because the 1450 posts it contains draw traffic regardless of the inactivity- I am providing here monthly updates of the pieces I write in my new blog here. Below is a list of posts published last month at the new site.

The Large Hadron Collider is Back Together – announcing the replacement of the last LHC magnets

Hera’s Intriguing Top Candidates – a discussion of a recent search for FCNC single top production in ep collisions

Source Code for the Greedy Bump Bias – a do-it-yourself guide to study the bias of bump fitting

Bump Hunting II: the Greedy Bump Bias – the second part of the post about bump hunting, and a discussion of a nagging bias in bump fitting

Rita Levi Montalcini: 100 Years and Still Going Strong – a tribute to Rita Levi Montalcini, Nobel prize for medicine

The Subtle Art of Bump Hunting – Part I – a discussion of some subtleties in the search for new particle signals

Save Children Burnt by Caustic Soda! – an invitation to donate to Emergency!

Gates Foundation to Chat with Bloggers About World Malaria Day – announcing a teleconference with bloggers

Dark Matter: a Critical Assessment of Recent Cosmic Ray Signals – a summary of Marco Cirelli’s illuminating talk at NeuTel 2009

A Fascinating New Higgs Boson Search by the DZERO Experiment – a discussion on a search for tth events recently published by the Tevatron experiment

A Banner Worth a Thousand Words - a comment on my new banner

Confirmed for WCSJ 2009 – my first post on the new site

Information control from CERN January 27, 2009

A piece by Matthew Chalmers titled “CERN: the view from inside” has appeared yesterday on Physics World’s web site. It is an insightful interview to James Gillies, head of communications at CERN.

The interview focuses mostly on the media coverage of the LHC startup of last September 10th, and the steps that made it a global success, with an estimated exposure of one billion people. The point is made that now “LHC” can be used out of context without problems, but I hope the revenues to science are larger than that.

More interesting to us science bloggers is the description of how information on the September 19th incident was provided by CERN, and the measures that were put in place to prevent unwanted, uncontrolled news from leaking out in blogs and other unauthorized media. The LHC logbook was edited, pictures of the incident were password-protected. I do not think this is too worrysome: the management decided it was the best thing to do under the exceptional circumstances, and I do not blame them for being tight.

The piece ends up discussing the restrictive policy of the lab and its experiments to blogging. The point is made that unconfirmed rumors damage science, but the matter is not really discussed in detail in any way. People keep claiming that discussion of unconfirmed signals is nocuous to Science, but I continue to hear that it is nocuous to their interests. Do director generals want to be the ones releasing important lab information to protect us, or to protect their chair ? Do principal investigators insist that results are released only after a publication is sent to the journal to avoid waves of imprecise physics from being distributed to unarmed citizens, or to increase their exposure when they make an announcement ?

I insist on being naive on this matter. I think that scientific results on basic science do not belong to their discoverers, nor to the experimental collaboration: they, as much as the data they are based upon, belong to the people.

In the Physics World interview, Gillies claims that the lab will act to counter the public discussion of not-yet-confirmed three-sigma effects (the article  mentions this corresponds to a “less than 1% chance for a statistical fluke”, but I guess it was Matthew to get this inaccurate to simplify matters for his numerically-challenged audience -the probability  is actually 0.3%). Well, I think the laboratory will have to be very careful to get down to the level of bloggers: the CERN management seems to talk and think as if blogging was a controllable phenomenon, but believe me, it ain’t. Not until they close the whole internet thing down.

In May 2007 an anonymous comment left in my blog on a large signal of supersymmetric Higgs decays seen by the D0 collaboration in events with four b-quark jets started a runaway phenomenon which ended on the New York Times and on Slate, plus other media around the world. The D0 collaboration was not happy about it, but what could they do ? The answer is simple: nothing. I wonder whether the CERN experiments have aces up their sleeves instead…

An agorà of education and scientific communication ? September 23, 2008

These are strange days. Information runs around the world so fast, one can be at the center of the action and still learn details of what is really going on from the other side of an ocean. In fact, CERN appears a bit up-tight about the latest events in sector 34 of the LHC tunnel. People ask me questions in the comments thread of posts here, but I have less information to provide than others; and I am happy it is so, since my blog is targeted as a possible source of leaks, and I decided I want this to be a place where people get educated about science, and not about scientific rows. And if I play fair, maybe I am allowed to survive here, and maybe one day I will stop being threatened every other day, in the name of protecting internal information of the experiments I am part of.

Of course, I still assert my complete disagreement at a way to conduct scientific experiments paid with your tax money which resembles the management of the Pentagon rather than an agorà of education, research, and scientific communication.

So, by all means, if you have information you want to share, anonymously or not, you are welcome to comment, but please, do not ask me for any.

Streaming video on scientific divulgation May 13, 2008

Just a link to a post by Gianandrea Giacoma on the site of the sci.bzaar.net workshop, an event about which I wrote here, here and here.

In the post, Gian uses very kind words to introduce a video on my thoughts on the need of horizontality in scientific blogs. I already posted a link to my video yesterday (beware, it is in Italian – I will try to find the time for an English version though, or at least provide a transcript in English), but the one on the sci.bzaar.net site does not need to be downloaded before playing – a huge bonus since you might get bored halfway through (oh well, damned if you do. It’s just 7 minutes).

A video on scientific blogging May 12, 2008

On Saturday, May 15th, a conference called “sci.bzaar.net” will take place in Milano. It will bring together a restricted group of researchers, psychologists, bloggers, designers, physicists, writers, philosophers, computer scientists and web experts, who will discuss scientific divulgation, production of knowledge, and open culture in the academic world.

I will not be there in person, but a video I produced for the event will be shown – and I will connect with skype or some other means to take questions. You can see the agenda of the workshop here.

In addition, I produced for the web site of the event another short video where I discuss the importance of horizontality in a blog aimed at scientific divulgation. Unfortunately, I only have a version in Italian so far (the event is aimed at an italian public). I will paste below a writeup as I have the time, but if you are interested you can see me in the 7-minutes video here (beware though, it is kind of heavy – 500 Mbytes!).
