A Nice bit of gas powered churnalism
BG and QGC have had to suspend construction of the coal seam gas pipeline to their planned LNG plant due to some of their environmental management plans not being approved. The story has highlighted the sorry practice in some media outlets of simply reprinting company press releases - Nice bit of gas-powered churnalism.

There’s a new service over in the UK set up by the Media Standards Trust which allows the public to check for cases of “Churnalism”.
Churnalism, says the trust, is “a news article that is published as journalism, but is essentially a press release without much added”.
Using the free Churnalism website, you can paste text from a press release into a box. The service then goes off and finds any news articles that resemble the text of the press release – articles suspected of being “churn”.
The site lets you see the press release placed side-by-side against the original and gives a percentage of how much of the release was cut-and-pasted and how many characters overlap.
In the last few days, they’ve added a service where you can do this exercise in reverse and search news outlets against press releases from some companies and government agencies.
For example, the site suspects that in the last three years 495 articles in The Guardian online may be churn. The Daily Mail online scores more than 700.
Now obviously, there are lots of occasions when there’s nothing at all wrong with a press release being churned. The trust points out that“Some press releases are clearly in the public interest (medical breakthroughs, government announcements, school closures and so on). But even in these cases, it is better that people should know what press release the article is based on than for the source of the article to remain hidden.”
Unfortunately,the site is only available in the UK but you can rest assured there’s plenty of churnalism that goes on in Australia too (If in any doubt, go check out Crikey’s Spinning the Media series from last year, which found over half of the news in Australia came from public relations). Some of it is harmless, but some of it is clearly not.
Which brings me to a recent article which appeared online in the Gladstone Observer and an almost identical story which appeared online in the Toowoomba Chronicle – both news sites owned by APN News & Media.
The story reported how the Queensland Gas Company had stopped work on clearing land for a coal seam gas pipeline because “environmental plans for soil and species management have not been approved”, the report said. A serious issue no doubt and well worth the time of an APN journalist in reporting it. After all, QGC has reported it is spending $15 billion on the project which the delay was part of.
There were quotes from “QGC senior vice president Jim Knudsen” who explained the company didn’t believe their work so far had caused any ”adverse impact on protected plants and animals”.
I asked QGC if they had issued a press release into the incident. They said they had and they sent me a copy. It’s now here online. Well, you’ve guessed the rest.
The story on the Towoomba site was almost identical to the press release, with only 5 words of the original 251-word press release changed. They didn’t even bother to write their own headline. “QGC stops work on pipeline”.
The Gladstone Observer story was identical, except for the addition of a 13 word intro popped on the top of the text. The rest of the story was a complete and unchanged cut-and-paste from the QGC release.
Why am I worried about this? Because a news outlet should not be just a distribution service for a major corporation, especially one which is drilling 6000 wells and laying more than 700 kilometres of pipeline in the areas being served by the news outlet.
I know regional newspapers have resources issues but surely its online readers should have been made aware that the story printed on its website was just a cut-and-pasted press release?
Good on QGC for admitting the breach, but you can only hope that the print versions of the Gladstone Observer and the Toowoomba Chronicle do better.

Evidence that quasars are powered by black holes
Astronomers see inside a quasar for the first time
The suspicion that quasars are powered by supermassive black holes has, until now, been based only on the fact that astrophysicists couldnt think of any other plausible explanation. The new evidence that supports this hypothesis is that it has been possible to observe what looks like a black hole accretion disk inside two quasars:
Further supporting their conclusion was the fact that the hightest-energy emissions (X-rays) occurred near the center of the quasar, while optical light originated much farther out. (Since gas and dust would be heated most near a central black hole.) It was possible to make these observations on two quasars only because they were magnified by gravitational lensing due to intervening massive objects, and only by by combining results from ground-based optical telescopes and the orbiting Chandra X-Ray Observatory.

For the first time, astronomers have looked inside quasars -- the brightest objects in the universe -- and have seen evidence of black holes.
The study lends further confirmation to what scientists have long suspected -- that quasars are made up of super-massive black holes and the super-heated disks of material that are spiraling into them.

The new evidence that supports this hypothesis is that it has been possible to observe what looks like a black hole accretion disk inside two quasars:
[The researchers] were able to measure the size of the so-called accretion disk around the black hole inside each quasar.
In each, the disk surrounded a smaller area that was emitting X-rays, as if the disk material was being heated up as it fell into the black hole in the center.
