I am spending a few days in Aix Les Bains, a pleasant lakeside resort in the French southwest, to follow the works of the second ECFA workshop, titled "High-Luminosity LHC". ECFA stands for "European Committee for Future Accelerators" but this particular workshop is indeed centred on the future of the LHC, despite the fact that there are at present at least half a dozen international efforts toward the design of more powerful hadron colliders, more precise linear electron-positron colliders, or still other solutions.
Yesterday the ATLAS collaboration published the results of a new search for dark matter particles produced in association with heavy quarks by proton-proton collisions at the CERN Large Hadron Collider. Not seeing a signal, ATLAS produced very tight upper limits on the cross section for interactions of the tentative dark matter particle with nucleons, which is the common quantity on which dark matter search results are reported. The cross section is in fact directly proportional to the rate at which one would expact to see the hypothetical particle scatter off ordinary matter, which is what one directly looks for in many of today's dark matte search experiments.
Do you remember the E-Cat ? That is an acronym for "energy catalyzer", the device invented by the Italian philosopher Andrea Rossi. The E-Cat is claimed to produce nuclear energy through the heating of a "secret" powder made up of nichel, hydrogen, and lithium plus some additives. A new chapter was added to the saga of the E-Cat this week, with the publication of a new study by an allegedly independent group of Italian and Swedish researchers.
"Fermilab has very actively tried to scoop us by press release, even though their uncertainties are under serious challenge and they knew our measurements even before they released theirs."

At the workshop I attended last week ("Publish, blog, tweet - furthering one's career in science") I discussed blogging for a researcher. One of the points I made was that through a blog a researcher may sometimes ask for the help of his or her readers, with usually great results.

Today I would like to put my own creed to the test, because I am searching for an article and I have no idea how to do it - usual searches with Google are insuccessful in this case. It is a newspaper article of 1989, which I need as it has relevance for a chapter of the book I have been writing.
Last Thursday and Friday I attended a workshop aimed at students of science communication and researchers who want to use the web tools to improve their collaboration networks and the visibility of their scientific output.

I gave a talk discussing the good and the bad sides of blogging about one's research. My contribution was very well received and I received great feedback from the organizers. You can find a live streaming (with the slides I am discussing also shown) at the workshop site, here: http://www.scicomm.it/p/blog-page_1.html . To see my talk go to h.mm.ss 1.17.00 .
