For medicinal purposes only...or so they say

Fruit flies use alcohol as a drug to kill parasites

Fruit flies infected with a blood-borne parasite consume alcohol to self-medicate, a behavior that greatly increases their survival rate, an Emory University study finds.

Salacious Friday

The first sexual revolution: Pleasure principles | The Economist

An interesting review of a book here about how sexual mores changed dramatically in the mid 18th century:

By the mid-18th century sexual mores in England (and in much of Europe, too) had undergone a revolution, writes Faramerz Dabhoiwala, an Oxford historian who has spent much of the last 20 years researching the subject. This rupture was far more dramatic than anything that happened in 1963 when, according to the poet Philip Larkin, “sexual intercourse began”. Less than 100 years after the execution for adultery of Mary Latham, a young woman in Puritan New England, many people were thinking about sex in ways that would make some contemporary readers blush. The wealthy and powerful proudly and openly displayed their mistresses. A public agog for salacious gossip followed the lives of courtesans and high-society prostitutes (such as the oft-painted Kitty Fisher), and pornography was widely available.
...as Mr Dabhoiwala persuasively argues, the reasons for the first sexual revolution were complex and varied. The migration of people to big cities had made the bonds of traditional morality much harder to enforce, while the explosion of mass-printed media both spread ideas and exploited prurient interest in sexual shenanigans. Exploration also had an influence, as travellers returned with tales of very different sexual cultures. But the key driver, Mr Dabhoiwala believes, was the spread of religious tolerance and nonconformity, which eroded the church’s authority and let people define morality more personally.
But for salacious, somewhat unpleasant detail, you can't go past this:
The upper-middle-class members of the Beggar’s Benison club in Scotland, founded in 1732, apparently thought nothing of arranging meetings where they could drink, sing and fondle naked women. Such evenings were brought to a fitting climax, as it were, when they would communally ejaculate into a ceremonial pewter platter.
I hope they didn't use it for the haggis the next day.

UPDATE: Tim's comment, of highly questionable taste, makes me keen to clarify that "it" in the last sentence refers to the platter...

I have had a further thought: assuming there might have been something on the platter to identify its intended use and history, you really wouldn't want one accidentally turning up on Antiques Roadshow. Valuer (to sweet old lady owner) "Well, this is very interesting indeed: do you know what the intended use was? It's a bit surprising..."

Money for nothing (or very little)

Heartland Documents Leaked, Climate Skepticism Exposed | Climate Central

Although the Institute is claiming one document is a fake, this is well worth reading.

Apparently, Bob Carter is getting $1667 per month from the Institute. Carter has not denied this; in fact, his non committal statement on the amount he receives can reasonably be implied to confirm it.

That's odd. His scientific work on climate scepticism convinces absolutely no one of scientific importance, as far as I can tell. (His last co-authored paper is still attracting attention for how wrong it was, with Michael Tobis questioning how it ever got published.) He doesn't even seem to have a very high profile in media appearances, if you ask me. (Actually, I see now that he did have a recent piece in The Australian, but seems to be his first for quite a while. Ian Plimer, the other geologist to make money out of being a professional AGW denier, keeps writing books for the Right to launch for him, and I would say has a higher profile.

Graham Readfern has a great post about this, which shows Carter's laughably hypocritical attitude to this revelation:

Professor Carter added: “The details of any of these payments are private to me. I can’t imagine that Heartland has released this document – so the question is, how this document was released.”

Scientists are paid not to have agendas or opinions, but to summarise the scientific evidence.”

Now I have to say I found this last statement pretty rich, coming from someone who is continually writing opinion pieces for newspapers and websites.

For example, during the carbon tax debate of last year, Professor Carter collectively described Chief Scientist Ian Chubb, Climate Change Minister Greg Combet, now Climate Commissioner Tim Flannery and former Australian Government climate adviser Professor Ross Garnaut as the “four horsemen of the climate apocalypse”.

Was this his opinion, I wonder? The kind of opinion he says scientists aren’t allowed to have?

It gets worse (the hypocrisy, that is):

“I’m a senior scientist and I speak in public on climate change. My scientific authority has nothing to do with who is paying me. I’m not implying a threat here, but I would advise you to be very cautious about what you impute. “
He said he “emphatically denies” any suggestion that his opinion on climate change was swayed by funders, but then stated this would not matter in any case.

“Professional scientists cannot have their opinion bought,” he said, adding it was not important who funded research, but whether or not it was correct.

This is an odd assertion for Professor Carter to make, given that he has regularly over the years attempted to suggest that mainstream climate scientists are motivated by research dollars.

As far back as 2006, in the UK’s The Daily Telegraph, Professor Carter wrote: “scientists are under intense pressure to conform with the prevailing paradigm of climate alarmism if they wish to receive funding for their research.”

Oddly, on Professor Carter’s webpage he chooses to state that he receives no research funding from “special interest organisations such as environmental groups, energy companies or government departments”.

Yet, if this funding doesn’t matter, then why make this statement? If he takes no interest in who funds his projects, then how would he know if he is receiving funding from “special interest groups” like those he describes.

I pointed out to Professor Carter that it was standard practice for scientists to disclose the funders of research when they publish in peer-reviewed journals. This, said Professor Carter, was “a very quaint and old fashioned practice”.
Of course, Carter has been noteworthy in the Institute of Public Affairs, which refuses to disclose funding too.

The Heartland leak at least shows what sensible people already knew - it is not interested in genuine science, it's a mere advocacy group that wants to dissuade the public's belief in genuine science.

This is, of course, what the IPA does as well.

As I suspected...

Contraception objections fail Catholic's moral reasoning – USATODAY.com

A very clear and convincing analysis explaining why, from a moral theology point of view, the bishop's objection to the Obama contraception compromise just does not stand up to scrutiny.

(Although, it doesn't deal with how the self-insurer compromise is supposed to work.)

As shared in Australia

David Frum on the GOP’s Lost Sense of Reality -- New York Magazine

I read this a while ago, but don't think I have linked to it before.

David Frum writes in detail, from an insiders perspective, about how the Republicans and the Right in the US have "lost touch with reality". It's a good summary of how the Right in the US has gone bonkers.

The Australian Right is, unfortunately, too readily infected by American ideas; such that, for example, means testing of a rebate for those on comfortable incomes (a family has to earn more than $166,000 to even start having it reduced) is called "class warfare".

Of course, those complaining the loudest about this also want the government to reduce the deficit. Tony Abbott is at least smart enough to recognise the benefit of this measure to helping him with the budget should he win government, and hence he won't promise to re-instate the rebate, and nor should he. If the Labor government runs its full term, the Coalition's opposition to the rebate change will have been largely forgotten anyway.

This is, I suppose, just routine political humbuggery and gamesmanship; but honestly, when you see the insistence from the American Right that for their deficit problems, the answer is to reduce taxes for the rich, you have to worry about how much their ideology will affect the Coalition.

Contraception and the Bishops, continued

dotCommonweal � Blog Archive � Conscientious objectors?

Of all the commentary around about the Obama compromise deal for the contraception mandate, I thought this blog post, and the comments following, were the best I have seen.

I also like this comment, although I think it might be an old joke I have heard before:
As always, Stephen Colbert captures the heart of the issue: “A woman’s health decisions are a private matter between her priest and her husband!!!”
There is the matter of how "self insured" institutions can work with this compromise deal. But if that can be sorted, I don't see either the Bishops or the Republicans benefiting from trying to keep this a live issue.

Not encouraging

Climate change causes harmful algal blooms in North Atlantic: study

The study, published in Nature found there has been a dramatic switch between the prevalence of to diatoms – two groups which include many of the microscopic planktonic plants forming the base of the ocean’s food chain.

The patterns show shifts in the distribution of species known to cause harmful effect through toxin poisoning.

The researchers, from Swansea University’s Institute of Life Science and the Sir Alister Hardy Foundation for Ocean Science in Plymouth said the effects of the shift could already be impacting UK waters, with shellfish harvesting sites off the Scottish west coast closing.

“Imagine looking at your garden one morning and finding that the grass had suddenly been replaced by bushes,” said Professor Graeme Hays, one of the paper’s authors from Swansea University.

“This may sound far-fetched but we have found changes of this magnitude in the biology of the North Atlantic, with a dramatic switch in the prevalence of dinoflagellates to diatoms.”

Using over 92,000 samples spanning 50 years from the Continuous Plankton Recorder survey, the team found that increases in temperature – a key element of climate change – had helped to drive this shift.

It's always worth asking whether this type of research is only finding something novel, or just something no one had previously looked for. But a 50 year survey of plankton seems a pretty good basis for saying significant changes have happened.

Quality journalism

I used to visit the Times of India to be amused at the lurid quality of their local crime reporting, but I think I may have found a site from Ghana with even more spectacular journalistic "flair":

A 53-year-old woman, Janet Appiagyei, went berserk and stripped an 18-year-old sales boy, Godfred Darko, and beat him to pulp by pulling and squeezing his genitals until they turned livid.

Janet Appiagyei, who is the wife of Apostle Daniel Boateng of Joyful Life Ministry International, a charismatic church at Kwashieman, and the sole importer of Mama Honey mackerel at Okaishie, accused Godfred of stealing GH¢1,600 from the sales they made on Friday, January 27 and Saturday January 28, 2012.

According to a source close to the Striking Force Unit of the Ghana Police Service, the woman stripped the boy after subjecting him to severe beatings and began to pull his manhood until it was bruised.
I like the bit about "sole importer of Mama Honey mackerel" thrown in the middle.

I see in another report with the headline
"Kennedy goes 'gaga' on Twumasi Appiah; calls him a “wee smoker” " there is a sudden outbreak of civility:
“I take [an] exception to what he said that I don’t even attend meetings. As a chairman as he is, even [when we were discussing the budget] how many times did he come with a clean face. You go and smoke your wee. .. He is a wee smoker, he goes out there, he doesn’t even do anything, please, please, I am not scared of that id***.”
Oh wait a minute. The lurid nature of the reporting includes a graphic photo of a dead alleged thief with a bullet hole in the chest. I won't link to that, but of the comments following the story (many doubting the police version of how they shot the guy), no one seems concerned about the photo.

Things are different in Ghana in many ways, it seems.

The anti-science candidate

Rick Santorum has been busy throwing red meat to the conservative anti-science base.

That he now appears to be a (almost) serious contender, at least in terms of present polling, is indeed a matter of grave concern for the state of the American Right.

The Colorado Independent reports:
The former U.S. senator from Pennsylvania argued that science has been hijacked by politicians on the left, and that climate change is “an absolute travesty of scientific research that was motivated by those who, in my opinion, saw this as an opportunity to create a panic and a crisis for government to be able to step in and even more greatly control your life,” Santorum said.

“I for one never bought the hoax. I for one understand just from science that there are one hundred factors that influence the climate. To suggest that one minor factor of which man’s contribution is a minor factor in the minor factor is the determining ingredient in the sauce that affects the entire global warming and cooling is just absurd on its face. And yet we have politicians running to the ramparts — unfortunately politicians who happen to be running for the Republican nomination for president — who bought into man-made global warming and bought into cap and trade,” he said, before criticizing presidential rivals Newt Gingrich and Mitt Romney by name for their previous positions on cap and trade and climate change.
Funnily enough, the relatively cautious and moderate climatologist John Neilsen-Gammon had a post out this past week entitled "Three Simple Facts About Carbon Dioxide" which begins:
Some things about carbon dioxide in the climate system are so firmly established and fundamentally important, you can use them as litmus tests to determine whether the person you are listening to is honest and knowledgeable. Note that somebody contradicting these facts may be dishonest or ignorant or both, but it’s usually not possible to tell which.

Fact #1: A small concentration of CO2 is a big deal.
Rick should read.

Does Hedley Thomas care to report this?

Brisbane Flooding 'Inevitable', Hydrologist Tells Flood Inquiry

Hedley Thomas and the Australian have been doing their best to convince the public that the Seqwater engineers were responsible for the Brisbane flood.

What then don't they report (as far as I can tell on the 'net) is this crucial bit of evidence yesterday by the independent hydrologist Mark Babister, we have to go to the Fairfax press to read about it. (Even then, it is not given much prominence):

In his report released last night, the hydrologist found that "although hindsight indicates a better flood mitigation result could have been obtained ... it would have been unjustifiably risky using the information available at the time".

"The primary factor when forming this view is that there would generally be no grounds to release large flows from Wivenhoe Dam during a flood event that are greater than the inflows so far received," the report says.

The strategies would have relied on operators releasing large flows from Wivenhoe in anticipation of drastic inflows.

"Between 11am on January 8 and 1pm on January 9, both of these strategies would have involved dam outflows significantly in excess [almost double] the peak dam inflow observed until that point," the report says.

"During this period, the above scenarios would have required Wivenhoe Dam to operate as a flood amplification dam rather than a flood mitigation dam.

"The only reason to increase flows so dramatically at such an early stage would have been if there was a sure indication that future inflows [would] exceed the remaining flood mitigation space in the dam, and that storage capacity should be 'created' for later."

When similar evidence was given in July 2011, Hedley Thomas and the Australian's article on it was headed "Qld flood damage 'could have been cut' "

The Australian's, and Thomas' reporting on this has been sensationalist and pretty disgraceful.Link

A likely story, Part 2...

Mills denies giving access to voicemails:

Earlier, the Australian owner of Big Pictures photo agency, Darryn Lyons, told the inquiry that photographers "didn’t know where they stand" when taking images of celebrities.

"We do not know from one day to the next whether they are going to want it or not," he said, speaking via video link from Australia.

"It is so ambiguous - we do not know what is right and what is wrong.

"Fifty per cent of celebrities want to be photographed and they love it but others will pick and choose their terms."

A likely story...

Ancient Antarctic lake thought to harbor prehistoric life, Hitler clones - CSMonitor.com

You should read the link - it's very amusing. And a little bit enlightening about Nazis.

There has been some odd links around on news.com sites saying something about the Russians drilling into the lake having "disappeared"; I thought it all sounded like nonsense from the Weekly World News (now sadly only a pale online imitation of its former self), but I didn't track down the source of the story.

The big fuel cell

Solvay’s 1 MW Nedstack Fuel Cell Delivers Impressive Performance During its First Two Months

We don't read enough about fuel cells and their potential contribution to cleaner energy. At the link above, you can see the photo of a very big one in Belgium, being run successfully for a couple of months, and apparently can power about 1400 homes.

A question of influence

BBC News - Did Charles Dickens really save poor children and clean up the slums?

The BBC looks at the question of how influential Dickens really was for social reform in the 19th century. Maybe not quite as much as people think, say some historians; but this has an air of pop contrariness about it if you ask me.

Climate change stuff

* Skeptical Science has a good post explaining Hansen's recent paper that details why they expect rapid warming in the near future.

* At Real Climate, a post on the study of tree rings, showing they don't well reflect cooling caused by volcanic activity. The end result is that this may have led to some underestimates of climate sensitivity.

* Nature reports that some measurements of the amount of leaking methane from at least one natural gas field indicate that gas may not be much better than coal for the warming atmosphere. There seems to be uncertainty as to how representative this is of other gas production areas, but it is still a bit of bad news.

Around the solar system by nuclear power

Robert Heinlein, writing in the the 1950's, used to have families cruising around the solar system via simple nuclear powered rockets (I remember the family discussion of the merits of different rocket models in The Rolling Stones - also known as Space Family Stone) and it may yet turn out that nuclear propulsion will be what gets astronauts around in future.

This report notes that NASA has had highly variable funding for nuclear rockets over the years, but they still think it has a lot of merit and may yet re-fund it to more realistic levels.

It's always going to be a bit controversial, though, getting the fuel into space on the top of a controlled explosion.

Speaking of Heinlein, I've recently bought a couple of Charles Sheffield novels from second hand stores. I've been reading him on and off for years, and am currently half way through The Web Between the Worlds.

He really does strike me as writing very much in the style of early Heinlein. He is more technically minded, but the way he sketches characters, has a basic optimism for the future of humanity, only ever implies sex and never describes it, and throws in the occasional off hand bit of future quirk (of the type "the door dilated", or "he took a bulb of beer") reminds me of Heinlein all the time.

I find him a very entertaining science fiction writer, and it's a pity he does not quite seem to have had the recognition he deserved. (He died a few years back.)

Worse than the disease...

gulfnews : Black magician stabs man 'to cure illness'

Time for a bizarre black magic story, this time from India:
Patna: The Bihar police have arrested a black magician who ruthlessly stabbed a man claiming that it would cure him of his mental illness and help him lead a normal life.

The 55-year-old accused was apprehended on Friday evening while he was stabbing the victim Taleshwar Murmu (45) at the latter's residence in the Mehboob Khan locality in eastern Bihar's Purnia district.

"The more you endure the pain of the stab, the faster the cure," the black magician kept on telling the victim who, police said, kept on screaming loudly due to the severe pain from the stabbing.

Zapping away fatherhood

'Sonicated' Sperm: Scientists Test Ultrasound as the Next Male Contraceptive | Healthland | TIME.com

Have I posted a story about this before?* I can't quite remember, but anyway, from the report above:
In the study, the rats’ testes were exposed to high frequency ultrasound at 3 MHz for 15 minutes each, two days apart. The sessions were enough to kill the existing sperm in the testes and stop the development of additional sperm. The first study to look at the effect of ultrasound on sperm production, in the 1970s, showed that the depletion was temporary, and Tsuruta hopes his studies will show the same result...
Some men are keen to get in on the technique:
Tsuruta stresses that the procedure isn’t something you should try at home, despite the fact that commercial ultrasound machines are available online and men are apparently purchasing them for this purpose. “I get emails asking me what conditions men should use,” Tsuruta says. “This is really not something you should do at home because we don’t know nearly enough about its safety and reversibility and what other effects there might be long term.”
I'm not sure that something that is working to disable sperm cells could be trusted to not be causing damage to testicular cells you don't want damaged.

* Yes I did - in 2010. It was a story about the same researcher in fact, and I am not entirely sure why this has made it to the news again last month.
