Same-sex science paper retracted

9:48 am

Politics corrupts science, again: The journal Science has retracted a paper that had claimed opinions on homosexual marriage could be changed quickly during a short conversation.

As noted in the journal’s retraction statement:

The reasons for retracting the paper are as follows: (i) Survey incentives were misrepresented. To encourage participation in the survey, respondents were claimed to have been given cash payments to enroll, to refer family and friends, and to complete multiple surveys. In correspondence received from Michael J. LaCour’s attorney, he confirmed that no such payments were made. (ii) The statement on sponsorship was false. In the Report, LaCour acknowledged funding from the Williams Institute, the Ford Foundation, and the Evelyn and Walter Haas Jr. Fund. Per correspondence from LaCour’s attorney, this statement was not true.

In addition to these known problems, independent researchers have noted certain statistical irregularities in the responses. LaCour has not produced the original survey data from which someone else could independently confirm the validity of the reported findings. [emphasis mine]

LaCour was the paper’s lead author. That he cannot provide the original data immediately discredits the work. It also discredits his only co-author, Donald Green of Columbia University, who apparently put his name on the paper without ever looking at the original data as well. When the above fraud was exposed, Green quickly called for the paper’s retraction, but I wonder how it was possible he allowed it to be published in the first place. Could it have been that he supports the idea of same-sex marriage, and wanted science to contribute its support as well, regardless of the facts?

Not being able to provide the original data is the same problem that Phil Jones of the Climate Research Unit had. Jones’ work documenting the global temperature for the past century has been the main source used by the entire climate field for decades, and when he couldn’t provide his original data, saying it was lost, his work should have received the same treatment as LaCour above — immediate retraction. Instead, Science protected him, as did the entire climate community.

Their willingness to cover-up Jones’ bad science is now coming back to bite them, with more examples of sloppy work getting into publication. Jones showed that it was all right to fake his results. LaCour decided to try it as well, and Green saw no reason to challenge the dishonesty. The result? Fake science done for the sake of homosexual politics.

The big difference now, however, is the willingness of Science to quickly retract the piece. It appears we are making some progress in re-establishing the rules of science to research and publication.

A minor side note: The author of the story above is John Bohannon, the same guy who just proved you can write a fake paper and get journalists to report it.

ALMA detects a solar flare on Mira 420 light years away

9:17 am

Mira A and Mira B

The just completed ALMA (Atacama Large Millimeter/submillimeter Array), a collection of 66 antennas located in Chile, has snapped a picture of the variable star Mira with its companion star, detecting details on the primary’s surface, including evidence of a solar flare.

Mira is a star with a mass like our Sun’s, but near the end of its life having evolved into a red giant that is shedding its outer layers. Being able to track its behavior with this kind of detail will allow astronomers to better hone their theories about the life and death of stars, including our own.

Another major image release from Rosetta

9:34 am

Time for many cool images! The Rosetta science team has just released to the public another batch of images from its navigational camera.

The 1776 images cover the period between 23 September and 21 November 2014, corresponding to Rosetta’s close study of the comet down to distances of just 10 km from the comet centre – 8 km from the surface – and the images taken during and immediately following the landing of Philae on the comet.

You can browse through them at your leisure, making your own discoveries if you have a sharp eye and know something about planetary geology.

A solar system like our own, but when it was a baby

9:28 am

Astronomers have discovered a very young 15 million year old star only 360 light years away that has a debris disk about the size of our solar system’s Kuiper Belt.

The ring is about the same distance from its parent star as the Kuiper belt is from the Sun, and receives roughly the same amount of light. Its blue-grey colour hints that it could consist of ices and rocky silicates such as those found in the Kuiper belt, says lead author Thayne Currie, an astronomer at the Subaru Telescope in Hawaii, which is run by the National Astronomical Observatory of Japan. “This is absolutely the closest example we have of a young Kuiper belt,” he says.

The best part of this discovery however might be how it was made, by using a new instrument on the ground-based Gemini telescope on Mauna Kea in Hawaii.

The instrument, which is part of the Gemini South telescope in Chile, uses a disk called a coronagraph to blot out the glare of bright stars. That allows it to take multi-wavelength pictures of faint, orbiting planets and debris disks around stars, by recording near-infrared light from the parent star as it scatters off the debris. The researchers discovered the disk around HD 115600 fewer than 6 months after the GPI began operation. A similar instrument, known as SPHERE, began operating in May 2014 on the European Southern Observatory’s Very Large Telescope in Chile and has also begun to make discoveries.

Assuming protesters don’t force Gemini to close, we should be getting a lot more exoplanetary discoveries from it in the coming years.

Russian rocket engines ready for shipment to U.S.

9:14 am

The competition heats up: An engine that Russia has developed for its Angara rocket has now been tested and is ready for shipment to the U.S. for use in the first stage of Orbital ATK’s Antares rocket.

This new engine will replace the refurbished Soviet-era engines Antares had been using previously that had caused the October launch failure. Note also that since Antares is not a military rocket, it does not fall under the Congressional ban for Russian engines that limits their use on ULA’s Atlas 5 rocket. As the article notes,

On Jan. 16, 2015, RKK Energia, parent company of NPO Energomash, announced that it had reached an agreement with the American company Orbital Sciences Corporation, OSC, on the export of RD-181 engines for the first stage of the Antares rocket, thus replacing the NK-33 engines previously used on the launcher. The contract, worth around $1 billion, was actually signed and ratified by the Russian government in December 2014. According to the document, a total of 60 RD-181 engines would be delivered to OSC beginning in June 2015.

This deal means that Antares will likely be back in business soon, though it will still be dependent on Russian-built equipment, which carries its own risks. It also means that Orbital ATK will not be able to sell Antares to the U.S. military, limiting its marketability.

It looks like the Moon!

9:03 am

craters on Ceres

Cool image time! Dawn has now swooped down to 3,200 miles, and provided a very nice image of the cratered surface of Ceres. Though it does appear to resemble the Moon, there are some differences that come to mind if you take a close look at the full resolution image. The surface appears smoother. All of the craters appear worn or eroded or less rugged. Also, there are no mountains. The terrain resembles the Moon’s lowlands or maria, but more so.

Note that the region in this picture is tantalizingly close to the double bright spot, but does not include it. Because Dawn is still easing its way into its first survey orbit of 2,700 miles elevation, it only takes pictures when it stops firing its ion engine, which it is doing almost all the time to get where it wants to be. Thus, they apparently only had time for this image.

The spacecraft enters its mapping orbit on June 3. Expect some cool images, including the first good images of the double bright spots, shortly thereafter.

A journalist and filmmaking team fake a study and the press buys it

10:54 pm

The uncertainty of science journalism: How a science journalist and two documentary filmmakers fooled millions (and many science journalists) into thinking that eating chocolate will help you lose weight.

My colleagues and I recruited actual human subjects in Germany. We ran an actual clinical trial, with subjects randomly assigned to different diet regimes. And the statistically significant benefits of chocolate that we reported are based on the actual data. It was, in fact, a fairly typical study for the field of diet research. Which is to say: It was terrible science. The results are meaningless, and the health claims that the media blasted out to millions of people around the world are utterly unfounded.

He then describes step by step how they did it. They even got their “research” published in a journal that claimed it did peer review but did not change one word of their submitted manuscript and published it less than two weeks after submission and the receipt of their money (science journals traditionally require authors to pay them for the honor of publication). In the end,

We landed big fish before we even knew they were biting. Bild rushed their story out—”Those who eat chocolate stay slim!”—without contacting me at all. Soon we were in the Daily Star, the Irish Examiner, Cosmopolitan’s German website, the Times of India, both the German and Indian site of the Huffington Post, and even television news in Texas and an Australian morning talk show.

The American women’s magazine Shape also fell for the fraud.

To me, the main reason the fraud worked was because none of the journalists involved ever bothered to actually read the science paper. They saw the press release, thought the story was cool, and simply rewrote the release. This is what happens repeatedly in the science field, and is why so much crap about climate science gets published. Too many reporters accept verbatim the claims of the scientists, doing no research to check the facts on which those claims were based.

I should mention also that John Bohannon, the man who played the scientist in this prank, also ran a sting operation against peer review journals in October 2013, creating a bogus paper and getting 157 journals to accept it for publication.

“These are the brownshirts of our time.”

7:45 pm

Link here.

Read it. Though the author describes an event that happened in 2003, it shows us ugly circumstances that have now become quite common, because as she says, “the ‘good’ people did nothing to disperse the hostility.” And unless we do something about it now — stand up to these fascist thugs who hide behind nice-sounding ideologies — what is happening today in the worst places in the Middle East is only showing us what things will be like here in another dozen years.

Russian rocket now garden furniture in England

5:36 pm

A British businessman has purchased a discarded Russian rocket and installed it in his garden as decoration.

Almost 40ft long and weighing five tonne, the rocket was first flown in 1991 after being built by the Russians in collaboration with NASA at a cost $10 million. For ten years it held the record for the fastest ever made-made machine before it was jettisoned as archaic.

Somehow it ended up at a car auction at South Marston where it was spotted by Mr Sweet while checking out vintage motors. Mr Sweet, who runs the Cirencester-based computer company Zycko, said: “I saw it for sale at a car auction and decided to buy it, not really knowing what I was going to do with it.”

I am curious how the rocket had ended up being owned and offered for sale by a UK company that “specializes in car restorations.” I also wonder if this might be a major new profit center for the struggling Russian rocket industry.

X-37B orbit uncovered

5:27 pm

Space hobbyists have pinpointed the classified initial orbit of the recently launched X-37B.

Observers this week spotted the craft flying overhead in a 194 by 202 mile orbit (312 X 325 km), tilted 38 degrees relative to the equator. That perch is lower than previous X-37B missions and the inclination is lower, too.

“OTV 4 entered the lowest initial altitude of the program,” said Ted Molczan, a respected satellite observing hobbyist. “The ground track nearly repeats every 2 days. Frequently repeating ground tracks have been a common feature of the program. This could be an indication of a surveillance mission, or it may offer some operational advantage I have yet to figure out.”

Not much else has as yet been uncovered.
