Today's bit of curious medical research

Magnetic fields reduce blood viscosity - physicsworld.com

In their experiment, Tao and Huang showed that applying a 1.3 T magnetic pulse to a small sample of blood can significantly reduce it's viscosity. About 8 ml of blood with a viscosity of 7 centipoises (cp) – above healthy limits – was contained at body temperature (37 °C) in a test tube. The tube formed part of a device called a capillary viscometer used to measure viscosities. The sample was then exposed to a magnetic field applied parallel to the direction of flow of blood via a coil around the edge of the test tube. After one minute of exposure to the field, the blood's viscosity had been reduced by 33% to 4.75 cp. With no further exposure to the field, the viscosity had only risen slightly to 5.4 cp after 200 min, which is still within healthy limits.

I guess it would be good to know how long the effect does usefully last for. Still, it's all very interesting.

Not exactly a night at the opera

Spat at by a naked dancer: St-Pierre's Un Peu de Tendresse

A Guardian reviewer gets more than he bargained for during a night at the dance theatre.

Really, it's just a case of the avant garde dance movement, such that it is, running out of ways to shock its audience. Pretty pathetic, really.

Finding dark matter in the dark

The Dark Matter Data Bonanza - Technology Review

An interesting account here of some (apparently) successful attempts to detect dark matter via experiments at the bottom of mines.

If confirmed, this would be a major step towards understanding the universe. I think.

Julia has a cow

Julia Gillard can't take a trick at the moment, that's for sure. The latest one being on the Indonesian cattle issue. Of course no one was happy seeing the conditions in some Indonesian slaughterhouses, but stopping the whole export industry for six months when thousands of cattle are about to get on ships?

This was also a rare occasion when Bob Katter also came close to making sense. On Lateline last night, he made the point that I have not seen much of in the media reporting: how the hell did the Australians involved in setting up that box system that is designed to get cattle on their side in about the clumsiest way possible ever think that was going to look good to Australian animal rights people?

As Katter said:

I mean, when I saw that box I just couldn't believe that anyone could have been so stupid as to design that thing. ...

This person tonight admitted that they knew what was going on, that they'd sent people in to have look at this, they knew what was going on and they've known for years and years and years about it and they've done absolutely nothing about it except to provide a stupid box.

If you're going to but the animal in a box anyway, why not make it one which properly holds the beast while you have access to slit its throat while thus constrained? Surely this is possible.

There was also a decent bit of commentary about the issue in an article in the Australian this morning too.

Speaking of Hitler...

Hitler's first draft of the Holocaust: unique letter goes on show | World news | The Guardian

Hitler apparently was writing of his anti-Semitic plans in a letter in 1919:

... Hitler spouted an antisemitic diatribe, in which he said Jews were "pure materialists in thought and aspirations" and that their effect was "racial tuberculosis on the nation".

Crucially, he went on to set out his vision for a calculated antisemitism that would operate through strong governments rather than the emotion of the people. Emotional antisemitism, he wrote, merely ended in pogroms.

"The antisemitism of reason must lead to a struggle for the legal battle to abrogate laws giving [Jews] favoured positions, differentiating the Jew from other foreigners. The final goal must be the uncompromising removal of Jews altogether. To accomplish these goals, only a government of national power is capable, and never a government of national weakness."

Sort of encouraging

Older age does not cause testosterone levels to decline in healthy men

A bit of a surprise finding from this study:

"Some researchers believe that an age-related testosterone deficiency contributes to the deteriorating health of older men and causes nonspecific symptoms, such as tiredness and loss of libido," he said.

Handelsman and his team, however, found that serum (blood) testosterone levels did not decline with increasing age in older men who reported being in excellent health with no symptoms to complain of.

"We had originally expected age to have an effect on serum testosterone, so the findings were a bit of a surprise," Handelsman said....

"The modest decline in blood testosterone among older men, usually coupled with nonspecific symptoms, such as easy fatigue and low sexual desire, may be due to symptomatic disorders that accumulate during aging, including obesity and heart disease," he said. "It does not appear to be a hormone deficiency state."

The message for patients and their doctors, Handelsman said, is "older men with low testosterone levels do not need testosterone therapy unless they have diseases of their pituitary or testes."

Quick, send this information to Strauss-Kahn's defence team: maybe they can make some use of it. (Actually, it may be worth their while getting his testosterone levels checked; if they are ridiculously high, it might be useful in the plea in mitigation.)

Jung the spy?

Carl Jung, part 2: A troubled relationship with Freud – and the Nazis | Mark Vernon

This is interesting.

The Guardian is running a series on Jung, as a way of noting the 50th anniversary of his death.

In this second part, I knew about the conflict with Freud before (from Jung's autobiography), but I didn't know about his WWII activities:

Jung is also accused of complying with the Nazi authorities, in particular with Matthias Göring, the man who became the leader of organised psychotherapy in Germany, not least because he was the cousin of Hermann Göring. In fact, Matthias put Jung's name to pro-Nazi statements without Jung's knowledge.

Jung was furious, not least because he was actually fighting to keep German psychotherapy open to Jewish individuals. And that was not all. Bair reveals that Jung was involved in two plots to oust Hitler, essentially by having a leading physician declare the Führer mad. Both came to nothing.

It has also come to light that Jung operated as a spy for the OSS (the predecessor to the CIA). He was called "Agent 488" and his handler, Allen W. Dulles, later remarked: "Nobody will probably ever know how much Prof Jung contributed to the allied cause during the war."

This could well form the basis of some fanciful fictionalised movie, I think. (It'd be good to see a fictional psychotherapy session between Jung and Hitler!) I like that genre of film.

How very generous...

Iran court quashes death sentence in 'porn' case | World news | The Guardian

A pretty amazing story of how dangerous a place Iran is:

Iran's supreme court has quashed the death sentence for Saeed Malekpour, a web programmer who was facing execution on charges of developing and promoting porn websites.

The 35-year-old was convicted of designing and moderating adult materials online although his family said he was a web programmer whose photo uploading software was used by a porn website without his knowledge.

Defence lawyers said the conviction was quashed after they provided the court with expert evidence. Malekpour, a Canadian resident who was arrested in October 2008 on arrival in Tehran, will remain in jail while a judicial review into his case is held.

Speaking from Toronto, his wife, Fatima Eftekhari, said: "This a sigh of relief for me, I'm very pleased that his life is finally saved.

"It's unbelievable that someone in this world has spent three years of his life in jail for merely designing software and was until now facing execution for that."

Caffeine brings hallucinations (Science Alert)

A somewhat interesting study suggests that drinking a lot of coffee will make you more susceptible to auditory hallucinations.

Actually, I'm not entirely sure that's a safe conclusion, when you read how the experiment was done:

Five coffees a day or more was found to be enough to increase the participant’s tendency to hallucinate says Professor Crowe.

‘High caffeine levels in association with high levels of stressful life events interacted to produce higher levels of ‘hallucination’ in non-clinical participants, indication that further caution needs to be exercised with the use of this overtly “safe” drug,’ he says.

The participants were assigned to either a high or a low stress condition and a high or a low caffeine condition on the basis of self-report. The participants were then asked to listen to white noise and to report each time they heard Bing Crosby’s rendition of “White Christmas” during the white noise.

The song was never played. The results indicated that the interaction of stress and caffeine had a significant effect on the reported frequency of hearing “White Christmas”. The participants with high levels of stress or consumed high levels of caffeine were more likely to hear the song.

Does a tendency to think you can detect a pattern like a song mean that you're actually hallucinating it? Debatable, I would have thought.

Poor IPA

I see that the IPA and its pet blog Catallaxy celebrated World Environment Day with a flurry of posts, like this one, to continue its argument against carbon pricing via posts encouraging disbelief in the existence of climate change requiring any response at all.

It's therefore encouraging to see that the IPA is disappointed that it can't find a politician who wants to meet Vaclav Klaus, the Czech President who likes to make profound, Lubos Motl approved, statements like this:

Global warming is a myth and I think that every serious person and scientist says so.

Julie Bishop says that Julia Gillard should not refuse to meet him just because he is a AGW sceptic. (I don't think "sceptic" is quite the right word for someone who makes silly statements such as the one I just quoted.) But the trip to Australia would seem not to be an official visit. It sounds as if he is coming here specifically for the seminars. Certainly the cost of attending one of the seminars ($235 for the general public!) makes it seem like the IPA has paid his first class ticket and have a lot of money to recoup. Presumably the host, Alan Jones (the IPA and Alan Jones - what a team) is donating his time.

What a pity it would be if the IPA makes a loss on this.

The thing is, they have ruled themselves out of participating in any serious discussion of the details of a carbon pricing, because everyone knows they are simply climate change denying polemicists.

The rate matters

New study indicates carbon release to atmosphere ten times faster than in the past

I think we already knew this, but this latest study estimates that the rate of CO2 release now is about ten times faster than the big release during the PETM event of 60 odd million years ago.

This is particularly important for the issue of ocean acidification, as the natural chemical buffering of the additional acid in the ocean from dissolved CO2 takes time.

Detecting primordial black holes

If A Primordial Black Hole Hits The Sun...� - Technology Review

Apparently, primordial black holes would pass through the sun and just cause it to wobble a bit; this may be detectable.

I think I have previously mentioned somewhere in this blog what might happen if a small black hole passed through the Earth.

Pirates, etc

I took the kids to see On Stranger Tides today. I would say it's a very solid "quite OK", but I don't really mean that to sound disparaging. The kids enjoyed it; I enjoyed it with them - it's one of the pleasures of parenthood to enjoy a film together with growing kids and be able to talk about it afterwards.

A few quibbles: too much of it is set at night or in gloom - I was missing the brightness of (I think) the second movie. I am also not sure that I prefer the direction of Rob Marshall over Gore Verbinski during action sequences. (I always find myself thinking "that's not how Spielberg would do it" during chases and action sequences that not done quite as well as they should.) But on the other hand, the script is pretty witty throughout - it certainly had more laughs in it than At World's End - and Penelope Cruz is good in her role.

I see from Wikipedia that a script for a 5th movie has already been finished. It did occur to me today, though, that as with the Indiana Jones movies, this series is fast running out of mythological ideas suitable to its period to be incorporated in the plot. The Flying Dutchman, kraken, voodoo, sea goddesses, zombies, mermaids and the fountain of youth have now all been covered. Oh well, I guess I'll find out in a couple of years time if there is something else mythological that has thus far been overlooked.

Speaking of the Flying Dutchman, I see that the Wikipedia entry about it is quite informative, and includes this interesting item which I think I may read years ago, but forgotten about:

There have been many reported sightings in the 19th and 20th centuries. One was by Prince George of Wales (b. 1865) (later King George V). During his late adolescence, in 1880, with his elder brother Prince Albert Victor of Wales (b. 1864) (sons of the future King Edward VII), he was on a three-year voyage with their tutor Dalton aboard the 4,000-tonne corvette Bacchante. Off the coast of Australia, between Melbourne and Sydney, Dalton records:

At 4 a.m. the Flying Dutchman crossed our bows. A strange red light as of a phantom ship all aglow, in the midst of which light the masts, spars, and sails of a brig 200 yards distant stood out in strong relief as she came up on the port bow, where also the officer of the watch from the bridge clearly saw her, as did the quarterdeck midshipman, who was sent forward at once to the forecastle; but on arriving there was no vestige nor any sign whatever of any material ship was to be seen either near or right away to the horizon, the night being clear and the sea calm. Thirteen persons altogether saw her ... At 10.45 a.m. the ordinary seaman who had this morning reported the Flying Dutchman fell from the foretopmast crosstrees on to the topgallant forecastle and was smashed to atoms.^[6]

Cool story, though not for the ordinary seaman.

For adults only - very silly adults

Californian porn industry's 'perfect storm' of troubles

A BBC report on the troubled porn industry in California notes:

Like the music industry, pornographers are struggling to persuade their audience to pay for what they watch.

DVD sales have collapsed. Online, a great deal of porn can be accessed for free.

And the economic downturn does not help.

"What with the recession and piracy, we call it the perfect storm," one leading producer observed wistfully

Yet, otherwise sensible, educated people still get into the business:

A college graduate, a former national standard swimmer and professional oboist, she seems to have packed a lot into her 27 years.

She turned to porn, she said, out of a sense of sexual adventure.

"It's just fun," she said, "and when everyone around you is having fun too, what's not to love?"

But what's really amazing is her attitude to the unprotected sex that is still the industry norm, despite government attempts to stop it due to HIV:

"And what about the health risks," I asked. "Have you had many infections?"

"Well, just chlamydia a couple of times, gonorrhoea - nothing much. Anyway, we test each month so, when you're diagnosed, you just take your medication and you're good to go. No problem."

In fact, the article goes on to note that some in the industry are attempting to argue that the right not to use a condom in the industry is a matter of free speech protected by the First Amendment!

"How can I express myself as an artist," one producer said to me, "if you're going to clothe my performers in rubber?"

Good grief. What a shame the industry is having hard times, hey?

Economic guesswork

'Discounting' The Future Cost Of Climate Change - Science News

Given that the economics of climate change are hot in the news again, I thought this explanation of discount rates was pretty good.

But still, my general attitude to all this is that it seems an absurd idea that economic modelling of the effects of climate change out to a century or so is anything other than pure guesswork.

The obvious reason is because of the uncertainties within climate science, even allowing that is basically right in its current estimate of likely global temperature increases. As the disruptive weather of the last 18 months is showing, it's not just heat waves to worry about, but floods, droughts, and possibly even unusually snowy winters at lower levels of the Northern Hemisphere. Everyone agrees that predicting regional effects is much less certain than the big picture, but this means we don't really know which population centres of particular economic importance are likely to be hit hard, and which get off relatively easily.

One of the largest consequences which I would have thought could be most important economically - sea level rise - is still very uncertain. If rate of sea level rise increases and it becomes clear that it will be at the top of the worst scenario forecasts, and thereby cause abandonment of major land areas and parts of some cities, how do you factor that into your economic forecasts now?

I guess this economic modelling is worth the exercise (and only attempted at all) as a way of trying to politically justify a certain level of current economic pain to offset future problems; but really, I find it hard to believe it can really be taken seriously as prediction if the actual effects of climate change are so difficult to predict.

It seems to me that using economics to work out the least costly method of getting to lower emissions is another matter, as that's comparing something that is relatively "here and now" and has aims which are in a more realistic time scale.

But the key point is, I think, average citizens wanting to see action on climate change should just be interested in serious movement to lower emissions done in a way that does not cripple the economy. Serious leadership on technological innovation that seems to be needed to achieve this will need to come as well.

BBC News - Global war on drugs has 'failed' say former leaders

The Global Commission on Drug Policy report calls for the legalisation of some drugs and an end to the criminalisation of drug users.

The panel includes former UN Secretary General Kofi Annan, the former leaders of Mexico, Colombia and Brazil, and the entrepreneur Sir Richard Branson.

Why not throw in Keith Richards for good measure?

Speaking of Branson, I quite like the new Virgin Australia ads where the flight crew are just walking around purposefully to a groovy beat. Maybe because it reminds me of the end credits of Buckaroo Banzai.

TEPCO, the plant's operator, ruled out the possibility of tsunami damage in a one-page memo filed to the Japanese regulator a decade ago, the Associated Press has discovered.

What a way to treat women

Egyptians protest over 'virginity tests' on Tahrir Square women

From the report in The Guardian:

The Supreme Council of the Armed Forces had previously denied claims by Amnesty International that 18 women detained in March were subjected to virginity checks and threatened with prostitution charges.

But an Egyptian general told an American television network on Monday that tests were in fact conducted, and defended the practice.

"The girls who were detained were not like your daughter or mine," the general, who requested anonymity, told CNN. "These were girls who had camped out in tents with male protesters in Tahrir Square, and we found … molotov cocktails and [drugs]."

He said the tests were conducted so that the women would not be able to claim that they had been sexually abused while in custody.

"We didn't want them to say we had sexually assaulted or raped them, so we wanted to prove that they weren't virgins in the first place," the general said. "None of them were [virgins]."
