Higgs announcement from CERN on December 13
CERN will be making an announcement on the status of its search for the Higgs particle on December 13. From this interview of one of its scientists:
The thing I know for sure is that [CERN Director General] Rolf-Dieter Heuer, who must know the results of both experiments, says that on December 13 we will not have a discovery and we will not have an exclusion.
The inteview is fascinating, as he notes how the Higgs research might also have a bearing on the search for dark matter.
“Also we have applied a completely artificial adjustment to the data after 1960, so they look closer to observed temperatures than the tree-ring data actually were.”

LightSquared touts new tests prove its internet service will not interfere with GPS
In a press event today, LightSquared announced that just-completed tests prove that its internet service will not interfere with GPS.
According to the company, the three private companies — Javad GNSS, PCTel and Partron — that make GPS equipment have been testing interference solutions and those tests have gone well. “Preliminary results show that GPS devices tested in the lab easily surpass performance standards thanks to these newly developed solutions,” Ahuja said. “We are confident that this independent testing will mirror testing being done by the federal government.”
Here’s another perspective:
Jim Kirkland, vice president of Trimble and a founding member of The Coalition to Save Our GPS, is trying to slow LightSquared’s momentum. “It is obviously extremely premature to claim at this point that these latest tests demonstrate that LightSquared’s proposed repurposing of the mobile satellite band for terrestrial operations is ‘compatible’ with high-precision GPS,” Kirkland says in a statement. “Even if new equipment solutions are fully tested and verified, these existing high-precision receivers will have to be retrofitted or replaced. LightSquared still refuses to accept the financial responsibility for addressing interference to existing devices, and so has not offered a comprehensive solution in any way, shape, or form.”

An update on the climate treaty talks in Durban
An update on the climate treaty talks in Durban.
I gather from this article that the talks appear to be going nowhere. (The reporter desperately wants a deal, and you need to read between the lines to sense how unlikely the deal is.) Not only is the U.S. reluctant to sign anything, so is India, China, and Brazil. Furthermore, even if the Obama administration agreed to something, it is highly unlikely any treaty could get through the Senate.
Also, it appears that the $100 billion Green Climate Fund is is in trouble as well.
All good news, as far as I am concerned. None of these deals have anything to do with climate or science. Instead, they are designed to redistribute power and wealth, by fiat, from one set of countries to another.
The trial of seven Italian earthquake experts facing manslaughter charges for not correctly predicting an earthquake continued this week.
The trial of seven Italian earthquake experts facing manslaughter charges for not correctly predicting a deadly earthquake continued this week.
The prosecution’s argument that the experts had underplayed the possible occurrence of a major quake was bolstered by testimony from Daniela Stati, the former civil protection officer for Abruzzo, who took an active role in the March 31 meeting. Stati confirmed what she had previously told prosecutors in 2010, that one of the indicted said during the meeting that the continuing tremors represented a “favorable signal” because there was a continuous discharge of energy that made stronger tremors less likely. In fact, scientific evidence suggests that groups of small earthquakes tend instead to increase the chances of a major earthquake nearby, even though the absolute probability of such a quake remains low. Stati said that nobody within the commission objected to this statement. She also underlined that the “reassuring message” given to the press by her, L’Aquila Mayor Massimo Cialente, and two of the indicted, Franco Barberi and Bernardo De Bernardinis, was based on comments made at the meeting.
Final results show the number of Atlantic hurricanes in 2011 was average, far less than predicted
The final results for the 2011 hurricane season show that the number of Atlantic hurricanes this year was completely average, not too many or too few, but well below what was predicted. See the graph at the bottom of the page.
Recent results from the Fermi Gamma-ray Space Telescope have found no evidence of dark matter, a result in some conflict with data obtained from several underground research detectors.
The uncertainty of science: Recent results from the Fermi Gamma-ray Space Telescope have found no evidence of dark matter, a result in some conflict with data obtained from several underground research detectors.
The mystery here is that there is no doubt that something causes the outer objects in galaxies to move faster than expected. Scientists have labeled this something as dark matter, guessing that some undetected and unknown mass exists in the outer reaches of galaxies, thereby increasing the gravity potential and hence the velocity in which objects move.
The problem is that they have yet to identify what that dark matter is.
