Handy figures to keep in mind

Beyond Condoms: The Long Quest for a Better Male Contraceptive: Scientific American

This article gives a pretty comprehensive coverage of the never ending quest to find a decent male contraceptive. I was most impressed with this line, though:
Compared with the one-egg-per-month output of the female reproductive system, the roughly 1,000-sperm-per-heartbeat output of the male reproductive system is "a quantitatively challenging problem" for contraceptive research, Amory says.
Young single men: feel free to incorporate this factoid during your next venture in a singles bar. Married men: impress your wife by offering this new found knowledge during a dinner party with that nice new couple you recently met.

There's one other quote that I thought interesting from the article:
In animal models the compound bisdichloroacetyldiamine safely and reversibly induces infertility by inhibiting an enzyme, aldehyde dehydrogenase 1a2, required for retinoic acid synthesis in the testes. Unfortunately, bisdichloroacetyldiamine also inhibits a similar enzyme, aldehyde dehydrogenase 2, required for alcohol metabolism in the liver—meaning that animals on bisdichloroacetyldiamine were unable to process alcohol. "And some would say that if it weren't for alcohol no one would need a contraceptive anyway," jokes Amory
What happens if you "can't process alcohol"? Would five drinks keep you drunk for a week? (I guess it takes a while to for it to get out of you via the lungs.) Would 12 drinks in a day pickle your insides?

Things achieved on a long weekend

* Unblocked the Vacumaid via the application of the old (normal) vacuum cleaner to the inlet that was not sucking. My handyman (handyperson?) credentials have soared, but from a very low base.

* Went to Lifeline Bookfest, and about the first thing I spotted, sitting in a face up position, was volume 1 of the famous multi-volume biography of Graham Greene by Norman Sherry. Purchased for $3, I doubt I will venture past this volume, but having read Greene's short autobiography of the first part of his life last year, I'm curious to see what he left out. See, I told you that the Bookfest was great.

* Saw Super 8. I'm surely not the first to say it, but it's "ET with teeth and a bad temper." I thought it was not bad, but not likely to linger long in memory; still, it's probably the best JJ Abrams movie I have seen. You see, long time readers know I have a problem with him, and dammit, he's still doing it.

He's the Director of the Giant Faces, who seems to think you need to be able to see skin pores to understand the emotion of a scene.

I get tired of pointing this out. Someone - Spielberg, his wife, his dog - I don't care who it is - tell him to frame a shot and then pull back half way and re-compose it. It is just the Abrams rule of thumb that will never let you down - "you are too close."

Anyway, as many reviewers noted, the young teenage(?) actors are really good, and the script as a homage to early Spielberg is quite good too. I liked the ideas better than the execution; but that always seems to be my fate with JJ Abrams.

* Taught the children how to play poker, as well as Pig. (I only found Pig as an adult in a Hoyles book, but it is a remarkably good party game for kids and adults.)

By nuclear power to the Pole

Last night, quite by accident, I saw the second half of Charlie Bird Explores the Arctic, in which the Irish journalist joins a Soviet nuclear powered icebreaker that takes passengers to the North Pole every summer.

The fact that this is now a quite routine tourist event that has been running for years had escaped my attention.

It costs about $20,000 per person, and the ship is quite well appointed, as far as nuclear powered icebreakers go. Once at the pole, everyone gets off and stands around a temporary North Pole pole stuck in the ice, a bar-b-q takes place on the ice, and several made people go for a dip in the water that is exposed around the ship.

Unfortunately, I can find no Youtube clip of this, but you can currently watch the show on the SBS TV website. The first half is spent with some Inuit, and there is a fair bit of discussion about how they definitely know the climate is changing.

I see that there is an old Youtube of an English woman making this trip in 2001, which gives you the general idea.

I must try and keep up more with fantasy ways to spend spare money I don't have.

Barr explains

Roseanne Barr: 'Fame's a bitch. It's hard to handle and drives you nuts' | Culture | The Guardian

I really did like Roseanne for the first 3 or 4 seasons. Like most sitcoms, it grew tired and was pretty much unwatchable (and unwatched) in its last season, but the first few years were pretty innovative in the way Barr describes in the article above.

In fact, in the first few paragraphs, Ms Barr sounds quite sensible, but then we get a long recount of how and why she felt abused soon after her famous sitcom started. I have read much of this before; it certainly sounds like it must have been a nightmare on the set for the rest of the cast while Roseanne and the producers/writers fought bitterly and openly. And who really know who's right here? Barr can swing wildly from sounding credible, to sounding half nutty.

But towards the end, she criticises Hollywood for tolerating the likes of Charlie Sheen, and here she is on the money again:

Based on Two And A Half Men's success, it seems viewers now prefer their comedy dumb and sexist. Charlie Sheen was the world's most famous john, and a sitcom was written around him. That just says it all. Doing tons of drugs, smacking prostitutes around, holding a knife up to the head of your wife – sure, that sounds like a dream come true for so many guys out there, but that doesn't make it right. People do what they can get away with (or figure they can), and Sheen is, in fact, a product of what we call politely the "culture".
But when it comes to his abusing his producers, she does relate:
Where I can relate to the Charlie stuff is his undisguised contempt for certain people in his work environment and his unwillingness to play a role that's expected of him on his own time.
Well, it seems to me Sheen has a lot less to complain about, given that (unlike Barr) he didn't get a comedy show by developing a character in years of tough stand up comedy. It seems he only had to lead a dissolute life, and a comedy based on that fell into his lap. (I'm assuming that's how it happened anyway.)

Finally, I note that The Middle - a very solid, enjoyable sitcom that is underappreciated - is a pretty clear successor to Roseanne. Maybe it's my own working class family background that makes me like these comedies.

A free plug

Brisbane Bookfest | Lifeline Community Care Queensland

Any South East Queensland reader is reminded that the Lifeline Bookfest is on at the Southbank Convention Centre this long weekend.

As their January one had to be cancelled because of the floods, I assume they will have a lot of books to sell.

You really should go; it's great.

And turning now to international hamster news...

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 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 " with low do not need 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."

Beautiful light

You too can hear music that's not there

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.
