Higgs announcement from CERN on December 13

9:14 am

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.

LightSquared touts new tests prove its internet service will not interfere with GPS

10:10 pm

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 audit by NASA’s inspector general finds that NASA can’t keep track of its moon rocks

3:47 pm

An audit by NASA’s inspector general has found that NASA can’t keep track of its moon rocks.

In a report issued by the agency’s Inspector General on Thursday, NASA concedes that more than 500 pieces of moon rocks, meteorites, comet chunks and other space material were stolen or have been missing since 1970. That includes 218 moon samples that were stolen and later returned and about two dozen moon rocks and chunks of lunar soil that were reported lost last year.

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.

2:11 pm

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.

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.

On the way to its winter haven, Opportunity found more evidence of water on Mars

4:27 pm

On the way to its winter haven, Opportunity found more evidence of liquid water that once flowed on Mars, specifically a geological vein that they think might be gypsum.

The vein examined most closely by Opportunity is about the width of a human thumb (0.4 to 0.8 inch, or 1 to 2 centimeters), 16 to 20 inches (40 to 50 centimeters) long, and protrudes slightly higher than the bedrock on either side of it. Observations by the durable rover reveal this vein and others like it within an apron surrounding a segment of the rim of Endeavour Crater. None like it were seen in the 20 miles (33 kilometers) of crater-pocked plains that Opportunity explored for 90 months before it reached Endeavour, nor in the higher ground of the rim.

According to what project scientist Steve Squyres said at a press conference today at the AGU meeting, “This is the single most significant piece of evidence that liquid water once flowed on Mars.”

An experiment designed to mimic the dynamo at the Earth’s core is about to be turned on.

8:43 am

Mad scientists at their best! An experiment designed to mimic the dynamo at the Earth’s core is about to be turned on.

Ten years in the making, the US$2-million project is nearly ready for its inaugural run. Early next year, the sphere will begin whirling around while loaded with 13,000 kilograms of molten sodium heated to around 105 °C. Researchers hope that the churning, electrically conducting fluid will generate a self-sustaining electromagnetic field that can be poked, prodded and coaxed for clues about Earth’s dynamo, which is generated by the movement of liquid iron in the outer core. If it works, it will be the first time that an experiment that mirrors the configuration of Earth’s interior has managed to recreate such a phenomenon.

This is a really very cool experiment, as we really do not have a good understanding of how planetary magnetic fields are produced.

Rumors of Higgs

8:35 am

Rumors of Higgs.

According to comments left on a number of particle physics blogs, the word is that the LHC is closing in on the Higgs. The Higgs boson is theorized to be the “force carrier” of the Higgs field — a field thought to permeate the entire Universe, endowing matter with mass. Only by using powerful particle accelerators like the LHC do we stand a chance of seeing these mysterious particles. Apparently, both the ATLAS and CMS experiments are independently seeing a Higgs signal, and the predicted mass of the particle agrees with the experimental results. In particle physics-speak, the Higgs appears to have a mass of 125 GeV (giga­electronvolts).

The rumors are fun, but this quote from the chief at CERN puts some damper on them:

“These results will be based on the analysis of considerably more data than those presented at the Summer conferences, sufficient to make significant progress in the search for the Higgs boson, but not enough to make any conclusive statement on the existence or non-existence of the Higgs.”

I suspect in this case we will need to wait for an actual announcement.

The Pathetic State Of Science Journalism

11:40 am

The pathetic state of science journalism.

Many survive as a science journalist just by paying attention to press releases and reproducing them, as long as others do the same. A recent BBC analysis of its science coverage in its own news reports revealed that 75% came from press releases, and only a tiny fraction contained views not expressed in those press releases.

This lip service is not good enough, and editors should wise up that science journalism has lost its edge and demand reform. It has also become uncritical and therefore not journalism. Too many who profess to practice journalism are the product of fashionable science communication courses that have sprung up in the past fifteen years. It’s my view that this has resulted in many journalists being supporters of, and not reporters of, science. There is a big difference.

I couldn’t agree more. I sometimes think my rants against “press release journalism” sound like a broken record. I am glad I am not the only one ranting.
