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.”

Ramping way up!

12:08 pm

The monthly update of the solar cycle graph produced by NOAA’s Space Weather Prediction Center was released yesterday. I have posted the graph below the fold.

The fast ramp up to solar maximum is continuing. For the fifth month in a row the Sun’s sunspot activity leaped upward. Not only has the sunspot activity once again exceeded the prediction for this particular time period, the activity is shot way above the solar maximum peak predicted for several years hence. This behavior is far different then what we’ve seen during the just completed long and deep solar minimum, when the Sun consistently underperformed the predictions for sunspot activity. Now it appears to be outperforming the predictions.

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.

From the AGU: All softballs for James Hansen

1:30 pm

Speaking of press release journalism, they just ended a press conference at the American Geophysical Union (AGU) fall meeting led by James Hansen, head of the NASA’s Goddard Institute of Space Studies in New York. Hansen is a devoted global warming scientist, most well known to the public from his testimony to Congress in 1988 outlining the serious threat the world faces from global warming and carbon dioxide increases in the atmosphere.

I had very much wanted to ask Hansen (as well as the rest of the panel) this somewhat challenging question:

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 explosive Kilauea volcano

10:41 am

At a press conference just completed at the American Geophysical Union meeting in San Francisco, geologist Don Swanson of the U.S. Geological Hawaiian Volcano Observatory revealed that the Kilauea volcano on the Big Island of Hawaii has been in an explosive mode about sixty percent of the time in the past 2500 years. “Kilauea is not the gentle volcano that most people assume,” noted Swanson.

Colorful Vesta

6:44 pm

False color of Vesta

Tonight’s press conference at the American Geophysical Union conference focused on the latest results from Dawn, orbiting the giant asteroid Vesta. Or to put it as scientist Vishnu Reddy put it, “Vesta is the most colorful asteroid in the solar system.”

At least, in geological terms. To our human eye the asteroid wouldn’t be so spectacular. However, the false color images released by the scientists show the global geological diversity of Vesta. From the press release:

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.

Voyager 1 at the edge

10:31 am

This week the American Geophysical Union (AGU) is having its annual fall meeting in San Francisco. Due to the wonders of technology, they are now making their press conferences available to reporters on line. Thus, I will be posting periodic updates after each conference. This will allow my readers to get a heads up on stories they will be seeing in the mainstream press in the next few hours.

Right now they are wrapping up a press conference from the team of the Voyager 1 spacecraft, in which they have described the spacecraft’s status.

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.
