Surprising news from inside your mouth

Well, I would not have expected this:

The bacteria in the human mouth – particularly those nestled under the gums – are as powerful as a fingerprint at identifying a person's ethnicity, new research shows.

Scientists identified a total of almost 400 different species of microbes in the mouths of 100 study participants belonging to four ethnic affiliations: non-Hispanic blacks, whites, Chinese and Latinos.

Only 2 percent of bacterial species were present in all individuals – but in different concentrations according to ethnicity – and 8 percent were detected in 90 percent of the participants. Beyond that, researchers found that each ethnic group in the study was represented by a "signature" of shared microbial communities.

"This is the first time it has been shown that ethnicity is a huge component in determining what you carry in your mouth. We know that our food and oral hygiene habits determine what bacteria can survive and thrive in our mouths, which is why your dentist stresses brushing and flossing. Can your genetic makeup play a similar role? The answer seems to be yes, it can," said Purnima Kumar, associate professor of periodontology at The Ohio State University and senior author of the study.

"No two people were exactly alike. That's truly a fingerprint."

Well, that's creepy...

Questionable link

Are California's giant dead oarfish a sign of an impending earthquake disaster? | News.com.au

I don't recall reading before that oarfish had been caught off Japan in large numbers before its Tohoku earthquake.   But it was reported in the Japan Times in March 2010, so the fish being caught in unusual numbers, and the folklore part, is true.  But then again, the earthquake was March 2011, so these oarfish are pretty extraordinary if they can forecast earthquakes a full year ahead. 

As I was saying a week or two ago....

A deafening silence: the media's response to asylum secrecy

It is remarkable how complacent Australia’s media has been in response to the federal government’s brazenly cynical suppression of information about asylum seeker boat arrivals. There were a few indignant editorials and then the circus moved on.

Kubrick's aliens

2001italia: 2001: The aliens that almost were

Here's a good article talking about all the trouble Stanley Kubrick (and Arthur C Clarke) went to in trying to come up with a credible cinematic alien for the climax of 2001.  

Of course, by not showing them at all, the movie suggests God-like mystery and power, which even goes beyond Clarke's so-called third law:  any sufficiently advanced technology is indistinguishable from magic.

It's just lucky that none of experimental aliens worked.

The return of mother possum....

She's been gone for many months, and the last possum visitor we had was a shy youngster who didn't hang around for long.  But today, the mother possum, easily recognized by the notch in one ear, was back.   Whether or not there is another baby in the pouch is not yet established.

Rubbing it in

A Push to Sell Testosterone Gels Troubles Doctors - NYTimes.com

The story starts:

The barrage of advertisements targets older men. “Have you noticed a recent deterioration of your ability to play sports?” “Do you have a decrease in sex drive?” “Do you have a lack of energy?”  

If so, the ads warn, you should “talk to your doctor about whether you have low testosterone” — “Low T,” as they put it. 

In the view of many physicians, that is in large part an invented condition. Last year, drug makers in the United States spent $3.47 billion on advertising directly to consumers, according to FiercePharma.com. And while ever-present ads like those from AbbVie Pharmaceuticals have buoyed sales of testosterone gels, that may be bad for patients as well as the United States’ $2.7 trillion annual health care bill, experts say.

Sales of prescription testosterone gels that are absorbed through the skin generated over $2 billion in American sales last year, a number that is expected to more than double by 2017. Abbott Laboratories — which owned AbbVie until Jan. 1 — spent $80 million advertising its version, AndroGel, last year.

Can anyone explain to me why Americans are so silly as to even allow such direct advertising of prescription drugs directly to the public?   Surely drug companies still make adequate monies from their products which are genuinely needed in those countries which do not permit such open advertising.

Old actor

Christopher Lee is 91.   Here he is receiving an award from an unrecognisable Johnny Depp.   (Depp must be one actor who can walk down the street with little fear of immediate recognition, his looks are so changeable from film to film.)  

Old skulls

Update:  I've been trying to post to the blog from various Android browsers with not much success. So this post with the following link:

http://theconversation.com/of-heads-and-headlines-can-a-skull-doom-14-human-species-19227

should perhaps be expanded.

The story, which I will now turn into a proper link,  is a pretty good summary of the strangely imprecise and (shall we say) excitable world of  evolutionary anthropology.

It's a subject I have trouble holding much interest in, to be honest, because it has always seemed to be an academic field in which there are particularly strong differences of opinion, yet they are all based on such limited evidence.  

I therefore like this story because it feels like a justification for not being interested in the subject.

And while on the topic of old skulls - I liked the documentary on SBS tonight about the surprisingly successful dig to turn up the skeleton of Richard III.   

Another Wes movie

It's very pleasing that, despite his (what seems) limited commercial success, Wes Anderson's eccentric films still manage to get funded and made.   Here's the amusing trailer for his next one.  (With the talented Ralph Fiennes in the lead, too.   As a good rule of thumb, any movie he is in, of any genre, is worth watching.)

Stress test

I'm feeling a bit overwhelmed at work at the moment.   Back soon-ish.

Here we go...

There is a feeling of doom approaching politics, when an eccentric rich man with no clear political or social philosophy and some hair-brained, half baked economic ideas is going to have considerable negotiating power in the Senate from next year:

CLIVE Palmer is demanding Tony Abbott repeal the carbon tax retrospectively and refund billions in revenue in exchange for his party's crucial Senate support in a move that would enable the businessman to escape a $6.2 million disputed charge for emissions.

The Palmer United Party has formed an alliance with the Australian Motoring Enthusiast Party's Ricky Muir, giving the bloc four of the six crossbench votes needed to pass legislation in the Senate without Labor or Greens support from July, subject to a recount in Western Australian.

PUP's official policy is to scrap Labor's carbon pricing regime but the party wants the repeal backdated to start of the carbon tax on July 1, 2012, so companies and households can be refunded.

The Coalition's election promise to scrap the tax is not retrospective, and Mr Palmer's push would force the government to refund the $3.6 billion raised last financial year and $6.5bn in receipts forecast this year.

"In relation to the carbon tax, we've said that we want it abolished from the day it was introduced because if it's a bad tax, it's always been a bad tax," Mr Palmer told the Ten Network.

Making problems disappear

Scott Morrison imposes information blackout on self-harm in detention | World news | theguardian.com

There is something really pretty appalling going on here in terms of political gamesmanship and media co-operation with it.

It suited the Coalition when it was in Opposition to have maximum media exposure of all problem associated with boat arrivals from Indonesia.

The media was happy to co-operate.

Now, it suits the Coalition to minimise media exposure of all problems associated with boats arrivals, and the involve the military in a weekly PR exercise in which limited information is feed out once a week.

Sure, the media can ask questions at these, and the response is increasingly "we won't talk about that for operational reasons."

If the media is not taking an active role in circumventing this attempted and cynical government control of the issue, I want to know why. 

Why is this approach not being the subject of criticism from commentators?   I really find it offensive.

And here's your weekly photo of the Tony Putin quasi military government in action:

Smacking Niall

Niall Ferguson names and shames me.

Amusing come back from Matthew Yglesias, who Niall Ferguson chose to drag into his feud with Paul Krugman:

The historian Niall Ferguson has decided for some reason to drag your humble blogger into his feud with Paul Krugman:

For too long, Paul Krugman has exploited his authority as an award-winning economist and his power as a New York Times columnist to heap opprobrium on anyone who ventures to disagree with him. Along the way, he has acquired a claque of like-minded bloggers who play a sinister game of tag with him, endorsing his attacks and adding vitriol of their own. I would like to name and shame in this context Dean Baker, Josh Barro, Brad DeLong, Matthew O'Brien, Noah Smith, Matthew Yglesias and Justin Wolfers. Krugman and his acolytes evidently relish the viciousness of their attacks, priding themselves on the crassness of their language.

In my case I'm genuinely unaware of a situation in which I employed crass language to amplify a Paul Krugman attack on Ferguson, though I certainly have had occasion to disagree with Ferguson when he misstates Mitt Romney's educational credentials or blames Barack Obama for rapid Chinese economic growth or says J.M. Keynes was a bad economist because he was gay. Ferguson might want to consider a meta-rational approach in which he wonders if the range of people who disagree with him about such matters doesn't possibly reflect Ferguson's own wrongness rather than the vast reach of the Krugman conspiracy.

Update:  Krugman refers us to a couple of other "acolytes" who have responded.  The one where Josh Barro reviews some of the things he has said about Ferguson is pretty funny.  

They seem to be pretty keen on Ferguson at Catallaxy threads.   I should have known that would mean that he has indeed said many stupid things about economics in the last few years, apart from the "Keynes was gay and therefore a crap economist" theory.
