An update on the climate treaty talks in Durban

2:17 pm

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.

The National Health Service of the UK is making its patient database available to researchers

5:08 pm

Coming to your US healthcare system soon! The National Health Service (NHS) of the UK is making its patient database available to researchers.

NHS plans to change its constitution to allow patient data to be open to researchers by default, with an opt-out option for individuals. The ability to take advantage of NHS data will be a boon for research in the United Kingdom, said Mark Walport, director of the Wellcome Trust. The more patients who are involved in research, the greater the public benefit, he said in a statement, adding that a patient once told him, “giving my anonymous data is the most painless thing I can do to help others get better.”

Some have raised privacy concerns about the data access plan, which is why the U.K. government will hold a public consultation on the idea before moving ahead, but Leszek Borysiewicz, vice-chancellor of the University of Cambridge, also applauds the proposal. [emphasis mine]

It is significant that the NHS’s constitution forbid the release of this data without a patient’s permission. I suspect that this privacy rule was almost certainly a condition used to convince Great Britain’s population to go along with nationalized healthcare. “Don’t worry about your health records! The nationalized healthcare system will be required to keep it private and available only to you!”

As is typical for a government program, this promise had an expiration date. Government programs like to control things, and they will inevitably do whatever they must — twist the facts, break promises, lie, cheat, — to gain that control.

Right now the patient health records are supposed to remain anonymous once they are released. Want to bet that in a few years these same scientists will demand that they need to know who the patients are in order to do their research effectively? And do you want to bet on whether that information remains secret?

Two newly discovered supermassive black holes weigh in as the heaviest known

11:48 am

Two newly discovered supermassive black holes weigh in as the heaviest known.

One of the newly discovered black holes is 9.7 billion solar masses and is located in the elliptical galaxy NGC 3842, which is the brightest galaxy in the Leo cluster of galaxies that sits 320 million light years away in the direction of the constellation Leo. The second is as large or larger and sits in the elliptical galaxy NGC 4889, which is the brightest galaxy in the Coma cluster about 336 million light years from Earth in the direction of the constellation Coma Berenices.

It is believed that these heavy supermassive black holes are the kind that produced quasars in the early universe.

U.S. military has rescinded its policy that banned bibles at Walter Reed hospital

8:49 am

U.S. military has rescinded its ban of bibles at Walter Reed hospital.

[Congressman Peter] King spoke from the House floor Thursday blasting a policy memorandum from the commander of Walter Reed National Military Medical Center written by Chief of Staff C.W. Callahan. The September 14th memo covers guidelines for “wounded, ill, and injured partners in care.”

“No religious items (i.e. Bibles, reading material, and/or artifacts) are allowed to be given away or used during a visit,” the policy states.

I suspect the original intent of the policy was to prevent the proselytizing of patients by outsiders. However, even this is a violation of the First Amendment, as the government has no right to say where and when people can discuss religion.

A collection of pertinent emails from Climategate 2

9:38 pm

A collection of pertinent quotes from Climategate 2.

I come to two conclusions as I read these and earlier emails.

  • The IPCC process has nothing to do with science and should not be considered a valid reference source.
  • The scientists involved are as unsure of the science as the skeptics, but don’t want anyone to know.

Both of these facts are important to recognize in order to decide what sources of information are reliable in studying this issue. And obviously, this means that almost any reports or press announcements coming out of Durbin this week are untrustworthy.
