JCU staff too scared to use their uni email – this is what “academic freedom” looks like

Academic Freedom in Australia: Academics are free to use hotmail at work

For the first time in months the ABC suddenly finds time to mention Professor Peter Ridd — not because he got sacked for an “uncollegial” email with the illegal line “for your amusement”.  The extraordinary threat to academic freedom was not newsworthy on the billion dollar ABC site.  Nor did the-blob’s ABC feel Australians needed to know that the international outcry over his sacking was so strong that Ridd raised $160,000 in donations in a couple of days. However now things are serious: other academics at JCU have given up using the official email network, hiding their thoughts on hotmail and gmail instead. Finally, 27 days after he was sacked, the ABC have started reporting.

Management of JCU insists Ridd’s sacking was not about academic freedom. But everyone at JCU acts otherwise. Staff at JCU now know exactly how free they are — if they say something the management doesn’t like, they too could be victims of a personalized email trawl. Anyone could lose their job at any time for falling foul of a selectively enforced and unknowable “code of conduct”.

James Cook University staff avoid using emails […]

NASA’s Space Science “Hide the Decline” Scandal

Guest essay by Eric Worrall

h/t Dr. Willie Soon – an outside researcher has uncovered what he alleges is an attempt by NASA JPL asteroid researchers to pass off other research results as the product of their model, possibly in an effort to conceal the shortcomings of the NASA model.

Two years of stonewalling: What happened when a scientist filed a public records request for NASA code

Retraction Watch readers may know Nathan Myhrvold, who holds a PhD in physics, as the former chief technology officer at Microsoft, or as the author of Modernist Cuisine. They may also recall that he questioned a pair of papers in Nature about dinosaurs. In that vein, he has also been raising concerns about papers describing the sizes of asteroids. (Not everyone shares those concerns; the authors of the original papers don’t, and astronomer Phil Plait said Myrhvold was wrong in 2016.) Last month, Myhrvold published a peer-reviewed paper as part of his critique. The final version of that paper went live today, as did a story about the science in The New York Times and a detailed explanation by Myrhvold in Medium. As the discussion over the results continues, here he shares his experience trying to obtain details about the methodology the authors used.

Two years ago, I uploaded a preprint to arXiv.org describing what I considered serious problems, including apparently irreproducible results, that I had uncovered when analyzing a set of research articles published by the NASA Jet Propulsion Laboratory (JPL) NEOWISE project. NEOWISE is the largest scientific analysis of asteroids ever conducted; the researchers on the project have so far published estimated sizes of more than 164,000 objects in the solar system, estimates they have claimed were all derived by applying a standard approach to raw observations from the WISE space telescope.

My findings generated quite a stir in the media, including stories in The New York Times, Science, and Scientific American, among other outlets. My hope and expectation was that shining light on these troubling issues would spur the JPL researchers to retract or correct their papers. At the very least, I thought, they would release the various unpublished techniques that they had used in a series of highly cited papers, stretching from 2011 to 2015, thus lifting the veil of secrecy that had prevented me and other astronomers from replicating their results.

As it turns out, my math was not wrong, and my findings were up to the challenge of intensive peer-review. Part one appeared in the prestigious planetary science journal Icarus in December, and the larger part twowas published last week. Key sections also appeared, after peer review, at planetary science conferences in 2016  and 2017.

NASA’s response got me wondering why the NEOWISE researchers were being so studiously recalcitrant. Typically, when you point out to scientists that they have goofed, they do one of three things: they say “oops!,” they ask you for proof of their error, or they bend over backwards to justify why they did things in an unconventional way. Instead, NASA issued a vague press release berating me with claims I had made a calculation error. (It was actually just a typo – and a red herring. Even if my math had been completely off, that wouldn’t explain or excuse evidence that some of the NEOWISE papers had passed off asteroid diameter measurements made by other researchers as asteroid model results that they had calculated themselves.)

What happens to turn students who idealistically study space science into paid researchers who allegedly cheat, lie and bully? When did protecting scientific reputations by any means become more important than telling the truth?

I personally find this sordid tale deeply shocking. The motives of scientists who cheat at climate science or medical research at least make an ugly kind of sense – a lot of money hinges on whether we face a climate emergency, or upon the acceptance or rejection of new pharmaceuticals.

But cheating at measuring the sizes of Asteroids; if this is true to me the actions of the JPL researchers defy comprehension. What possible motivation could scientists have to cheat on the measurement of Asteroids? Nobody cares if a result has to be corrected. Nobody loses money if they have to revise their method. If space science models produce defective results, surely all they need to do is apply for more grant money to help them improve their models.

Why would anyone do this? Someone inside NASA must have helped these scientists perpetrate their alleged coverup. Just how deep does the rot go?

RIVERSIDE, Calif. — We’ve all heard about the search for life on other planets, but what about looking on other moons?

In a paper published Wednesday (June 13) in The Astrophysical Journal, researchers at the University of California, Riverside and the University of Southern Queensland have identified more than 100 giant planets that potentially host moons capable of supporting life. Their work will guide the design of future telescopes that can detect these potential moons and look for tell-tale signs of life, called biosignatures, in their atmospheres.

Since the 2009 launch of NASA’s Kepler telescope, scientists have identified thousands of planets outside our solar system, which are called exoplanets. A primary goal of the Kepler mission is to identify planets that are in the habitable zones of their stars, meaning it’s neither too hot nor too cold for liquid water — and potentially life — to exist.

Terrestrial (rocky) planets are prime targets in the quest to find life because some of them might be geologically and atmospherically similar to Earth. Another place to look is the many gas giants identified during the Kepler mission. While not a candidate for life themselves, Jupiter-like planets in the habitable zone may harbor rocky moons, called exomoons, that could sustain life.

“There are currently 175 known moons orbiting the eight planets in our solar system. While most of these moons orbit Saturn and Jupiter, which are outside the Sun’s habitable zone, that may not be the case in other solar systems,” said Stephen Kane, an associate professor of planetary astrophysics and a member of the UCR’s Alternative Earths Astrobiology Center. “Including rocky exomoons in our search for life in space will greatly expand the places we can look.”

The researchers identified 121 giant planets that have orbits within the habitable zones of their stars. At more than three times the radii of the Earth, these gaseous planets are less common than terrestrial planets, but each is expected to host several large moons.

Scientists have speculated that exomoons might provide a favorable environment for life, perhaps even better than Earth. That’s because they receive energy not only from their star, but also from radiation reflected from their planet. Until now, no exomoons have been confirmed.

“Now that we have created a database of the known giant planets in the habitable zone of their star, observations of the best candidates for hosting potential exomoons will be made to help refine the expected exomoon properties. Our follow-up studies will help inform future telescope design so that we can detect these moons, study their properties, and look for signs of life,” said Michelle Hill, an undergraduate student at the University of Southern Queensland who is working with Kane and will join UCR’s graduate program in the fall.
