The Fukushima nuclear reactor has reached the state of cold shutdown

Good news: The Fukushima nuclear reactor has reached the state of cold shutdown.

This means that the reactor core has cooled enough that there is no need to recirculate the water to keep the fuel cool. However, because the reactor continues to leak that water recirculation is still necessary, and will be for years.

As is typical of many modern journalists, the article above is also an unstated editorial both hostile to nuclear energy as well as private enterprise, best shown by the article’s concluding paragraph:

Meanwhile, the Japanese public and many of its politicians remained deeply mistrustful of the situation at Fukushima. In this week’s issue of Nature, two members of the Japanese parliament call for nationalization of the Fukushima Plant, to allow scientists and engineers to investigate exactly what happened inside the reactors, and to reassure the public that the decommissioning will be done with their interests at heart. Regardless of whether you agree with the authors, nationalization seems almost inevitable. The lengthy decommissioning process that will follow this cold shutdown, and the enormous cost involved, make it a job for a government, not a corporation. [emphasis mine]

First, he has no idea what the Japanese public thinks of this situation. Second, there is no evidence that the government could do this job better than the company that runs the reactor. Both conclusions are mere opinion, inserted inappropriately in a news article without any supporting proofs.

NIH and DOE in the proposed budget deal

The National Institutes of Health (NIH) and the science office in the Department of Energy (DOE) appear to avoid serious cuts in the proposed budget deal.

Actually, NIH’s budget remains almost identical to what it got in 2012, $30.6 billion. However, this amount is $1.4 billion more than it got in 2008, and $1.7 billion more than it got in 2007. As for DOE’s Office of Science, the $4.889 billion for 2012 is still $700 million more than the office got in 2008.

In other words, considering the budget deficits the federal government faces, these 2012 budget numbers hardly seem to be a reasonable attack on the problem. Simply bringing those budget numbers back down to 2008 numbers would hardly damage the work these government agencies are doing, and it would surely do more to reduce the deficit.

Scientists have found microbes inside a lava tube that can thrive in the freezing cold and low oxygen environment of Mars.

Scientists have found microbes inside a lava tube that can thrive in the freezing cold and low oxygen environment of Mars.

In a laboratory setting at room temperature and with normal oxygen levels, the scientists demonstrated that the microbes can consume organic material (sugar). But when the researchers removed the organic material, reduced the temperature to near-freezing, and lowered the oxygen levels, the microbes began to use the iron within olivine – a common silicate material found in volcanic rocks on Earth and on Mars – as its energy source.

Rider on the Storm

Rider on the storm.

At approximately 6:00 pm, Lt Col Rankin concluded that his aircraft was unrecoverable and pulled hard on his eject handles. An explosive charge propelled him from the cockpit into the atmosphere with sufficient force to rip his left glove from his hand, scattering his canopy, pilot seat, and other plane-related debris into the sky. Bill Rankin had spent a fair amount of time skydiving in his career—both premeditated and otherwise—but this particular dive would be unlike any that he or any living person had experienced before.

Or since.

A Russian scientist has found large amounts of methane being released in the atmosphere in the Arctic

A Russian scientist has found large amounts of methane being released into the atmosphere in the Arctic, far more than previously predicted.

It is speculated that these releases are the result of the Earth’s warming climate during the past several hundred years. And because methane is a far more powerful greenhouse gas than carbon dioxide, its release will feed into that warming.

Walking through the new American Amundsen Scott South Pole station

An evening pause: In honor of the 100th anniversary of Roald Amundsen’s arrival at the South Pole on this date, 1911, lets take a tour through the recently completed new Amundsen Scott South Pole station.

At one point right after walking through the cafeteria the cameraman points the camera out a window where you can see several flagpoles. That is where the actual South Pole is located. The camera than looks out a second window at a partly buried dome, which is the old station, no longer in use.

This video astonishes at what humans can accomplish in the most hostile environments.

CERN announces an update on the search for the Higgs Boson

Not there yet: CERN announces an update on the search for the Higgs Boson.

The main conclusion is that the Standard Model Higgs boson, if it exists, is most likely to have a mass constrained to the range 116-130 GeV by the ATLAS experiment, and 115-127 GeV by CMS. Tantalising hints have been seen by both experiments in this mass region, but these are not yet strong enough to claim a discovery.

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.

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.

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.
