Super cool

Airbus A380 - cockpit | p a n o r e p o r t a g e | g i l l e s v i d a l

All readers with even the slightest interest in aviation must immediately click on the link to have a look at this very, very cool panoramic picture of the inside of a new Airbus A380 cockpit. You can zoom in close enough to read many of the buttons up on the overhead panel. You can look behind the seats. You can marvel at the joystick and other weird thingee that they evidently use to fly this gigantic plane. Hey, are they cupholders I see? (Probably not, but who knows.)

Love it. Thanks to CNET for the link.

Sperm 'tap' planned for reversible vasectomy - tech - 28 January 2008 - New Scientist Tech

From the story:

A radio-controlled contraceptive implant that could control the flow of sperm from a man's testicles is being developed by scientists in Australia.

The device is placed inside the vas deferens – the duct which carries sperm from each testicle to the penis. When closed, it blocks the flow of sperm cells, allowing them to pass again when it is opened via a remote control. The valve could be a switchable alternative to vasectomy, the researchers say.

Some time ago I posted about the issue of ongoing pain sometimes caused by vasectomies. Given that it is believed that the type of vasectomy which seals off the vas deferens on the "supply side" of the cut is more likely to cause pain, I expect that any implantable plug within the vas is also at risk of having higher rate of pain.

Even as a person who only watches a handful of sports programming every year, I found the Australian Open final last very enjoyable. (Although the wild upset of a Tsonga win would have been even better.)

I was curious at the end as to how much Tsonga got as the consolidation prize. Now I know: $685,000. Not bad, hey.

Paul Sheehan holds a diametrically opposite view to mine about the current state of Hollywood:
We really are living in a golden age of cinematic literature and film is the literature of our age. We are a fifth-generation cinema culture and it shows. Filmmaking is imbued with the experiences of several generations and more good and knowing and ironic films are being made than ever before....

It is surely a golden age when the Coen brothers, Ethan and Joel, are making film after glorious film, when eccentrics like Wes Anderson and Jim Jarmusch are pumping out movies for cult followings, and when a new generation of talented filmmakers has dominated the Academy Awards.
I was under the distinct impression that Wes Anderson and Jarmusch no longer attract success of either the critical or popular kind, and the Coen brothers are pretty hit and miss now too. While I like some of the Coen movies, I have never quite gotten over Fargo, which was the biggest case of the cinematic emperor having no clothes I have ever seen.

Paul Sheehan is probably of the same school that saw the early 70's as a exciting period of Hollywood artistry, whereas all I could really see was a string of dark films with depressing themes, basically reflecting a the political malaise in the West at the time. Pretty much the same thing is going on now.

Mercury in fish questions answered

Biggest and best tuna tend to have the most mercury, experts say - International Herald Tribune

My questions raised earlier this week about mercury in fish are largely answered in the above article.

Here are some points worth noting:
The higher the fish in the food chain, the more it collects mercury. Sharks often have levels of mercury over 2 parts per million, but their meat is rarely consumed in the developed world.
Except in Melbourne suburban takeaways, of course.

As to where this mercury in fish flesh is coming from:
Since tuna spend most of their time far out at sea, scientists believe that most of the mercury they absorb occurs naturally and is dispersed in the oceans by historic volcanic activity. Close to land, industrial sources can emit mercury as a pollutant. And since tuna spawn in shallow waters, local industrial pollution could have some influence on contamination of tuna flesh.
This answers my question about how orange roughy, a deep sea fish, acquires mercury in its body.

As to how dangerous the levels of mercury in tuna are:

The ill health effects of mercury in tuna and other large fish are a topic of active debate in the global scientific community, and many scientists caution against an exaggerated response - noting that fish is generally more healthful than red meat. In high doses, mercury is a neurological toxin.

But the health risks are greatest for pregnant women and nursing mothers who may pass mercury to their infants. When it comes to adults, "I think there is a little scare-mongering here," said Dr J.J. Strain a nutritionist at the University of Ulster who has been studying the health effects of fish-based mercury ingestion on young children in the Seychelles. "Fetal brain is at least ten times more sensitive than adult brain, so the health risk, if any, relates to pregnant women, not other adults."

And there is another complication to take into account too:

Research also suggests that the toxic effects of mercury is canceled out if it is ingested alongside selenium - and most ocean fish contain both elements. There's now a lot of evidence to suggest that "excess selenium over mercury equals healthy food; excess mercury over selenium equals potentially harmful food," Dr. Kaneka said.

"We shouldn't focus just on the negative risk of eating fish - yes, there are these contaminants, but there are also huge benefits. This is a work in progress and it's a very complicated risk/benefit analysis," Valdimarsson said.

Well, glad that's all sorted out. Or not, as the case may be.

How the classics used to be

What Music Has Lost - WSJ.com

I've heard a bit about this topic before: how the modern way of listening to classical music does not bear much resemblance to how it was performed in the days the work was created.

This review of a book on the topic gives a bit more background:
There was a whole tradition of "concert improvisation." The young Franz Liszt would improvise on themes offered by concert-goers to such effect that his listeners were left in a state of delirium. Audiences in the 19th century, themselves less rigidly bound than audiences today, got into the spirit by voicing their enthusiasm when a passage moved them -- interrupting with applause or shouts and sometimes demanding, mid-concert, a reprise. They applauded between movements as well.
Much of the blame for the stifling formality of performance today is, apparently, the fault of a prominent later figure in music:
Mr. Hamilton shows how much of our present performing etiquette derives from Felix Mendelssohn and Clara Schumann, whose antipathy to interpretative license (and to Liszt, its exalted practitioner) bordered on the pathological. "It is inartistic, nay barbaric, to alter anything they [composers] have written, even by a single note," said Mendelssohn. His style demanded strict meter, the avoidance of expressive ritardandos, utter fidelity to the page and minimal pedal. No wonder, as Mr. Hamilton drily notes, that on the wall of the Leipzig Gewandhaus (where Mendelssohn played and conducted) was Seneca's apothegm: "Res severa est verum gaudium." That is: "True joy is a serious business."

So much for the evil Howard agenda...

Well there you go. An Aboriginal leader with impeccable Labor credentials thinks Labor should not be re-instating the permit system removed by the Howard government.

Will this make the latte Left re-consider their position that the Howard move was the true evil purpose behind the Northern Territory intervention, and that there was no way it was connected to improving aboriginal life? I seem to recall lots of people at Larvatus Prodeo were running this line.

Bloody songs

Sweeney Todd: The Demon Barber of Fleet Street | Reviews |

Not being sure that I have ever heard a Sondheim song or bit of music that I particularly liked, I am in no rush to see a movie that combines his musical oeuvre with Tim Burton's Goth sensibility and lots of blood. Peter Bradshaw (above) has this to say in his review:
Depp stars in Tim Burton's screen version of Stephen Sondheim's neo-Victorian horror panto Sweeney Todd, for which critical superlatives more appropriate for the Sistine Chapel ceiling have been lavished. I have to admit to being agnostic; for me, Sondheim's music, though forceful and fluent, slides through the mind leaving me with a faint hankering for the vulgar satisfactions of memorable tunes.
And Anthony Lane wrote:
So, how do you rescue the hell brew from absurdity? The answer, for Sondheim, is dexterity: the unstinting sophistication of his wordplay and his flirtatious harmonies—forever hinting at the sweeping show tune, only to duck away into discord and off-key fretfulness—is a riposte to his silly plot.
Hmm. It seems a fairly common assessment that much of Sondheim's music is clever, but not "hummable", and people expecting a memorable show tune often feel "cheated". The Wikipedia entry about him is interesting: he's had his fair share of failed musicals, and there is this odd line:
The failure of Merrily greatly affected Sondheim; he was ready to quit theater and do movies or create video games or write mysteries.
A video game by Stephen Sondheim?

The other mystery about his Wikipedia entry is that it says nothing about his adult personal life. Looking at some other websites indicates that the issue of his sexuality has been pretty complicated (one site says he didn't come out as gay until he was in his 40's, and even then he didn't fall in love with a man 'til his 60's. He also nearly married actress Lee Remick when he was younger.) So why is there is absolutely nothing in his Wikipedia entry about this part of his life?

Despite it getting a very high rating on the Rottentomatoes scale, I think I'll give Sweeny Todd a miss. (It's taken nearly $50 million at the US box office after a month, which suggests most people have decided the same.)

A musical interlude

Last month, I mentioned that I had seen the 1999 DVD version of Joseph and the Amazing Technicolor Dreamcoat and was very impressed.

Since then, my clever wife found it at Target for about $12, and it is currently on high rotation still with the kids. I am still finding it exceptionally enjoyable after repeat viewings.

Have a look at the Pharoah's Song, which is always viewed as the highlight of the show. Even if the pastiche Elvis song doesn't immediately impress (it is pretty catchy, though), perhaps you will see why I admire the editing and the way the whole thing is done:


I also think I have a middle age crush on Maria Friedman (the narrator).

Reason for moving to the Moon

Could WR 104 Threaten Earth?

Recent studies of supernovae have explored whether there is a link between these exploding stars and gamma-ray bursts (the most energetic events known in the Universe). In the case of WR 104, it is possible that when the Wolf-Rayet star explodes, much of the energy and matter will be ejected at the polar ends – and Earth is virtually pole-on to the system.

Our understanding of the connection between supernovae and gamma-ray bursts is still in its infancy, but Tuthill and his colleagues suggest that there is a possibility that WR 104 might produce a gamma-ray burst – one that would be only 7,000 light-years from us (as good as on our doorstep).

The good news is that we probably have several hundred thousand years before the Wolf-Rayet star in question does explode.

Europe tries again

European energy | An EU plan to cut hot air | Economist.com

The Economist looks at the EU's plans for CO2 targets. This section is noteworthy:
The trick of managing both to save jobs and the planet will mostly be left to the EU’s Emissions-Trading Scheme (ETS). This obliges big polluters such as power companies or industrial giants to trade permits allowing them to emit tonnes of carbon dioxide, and other climate-change nasties, within a steadily tightening overall cap. So far, firms have received some 90% of their permits free (letting some earn fat windfall profits by charging customers for their nominal cost).
Different countries will also be allowed different targets:
Sweden, for example, will be asked to meet 49% of its energy needs from renewable sources like hydro-electric power, or nifty heating plants that burn wood or straw. Yet tiny Malta (a sun-drenched but crowded rock near Italy) has been given a renewables target of just 10%. It is a similar story when it comes to cutting greenhouse gases: wealthy Denmark must cut its emissions by 20% by 2020, against 2005 levels. Bulgaria and Romania, the union’s newest and poorest members, will be allowed to let their emissions rise by some 20%.
Late last year, The Guardian reported that there is "severe scepticism" about the 20% renewable energy target in Britain. The Financial Times has a significant problem with the renewables target too.

I'm just sceptical any time the EU claims it is taking the "high moral ground".

Big trouble in big China?

Earnings illusion threatens Chinese market: Wei Gu | Special Coverage | Reuters

Waiter, waiter, percolator

High society - Health - Specials - smh.com.au

I had no idea that the levels of caffeine from espresso could be so wildly different:

Unless you drink instant coffee, it is impossible to control your caffeine intake if you're a regular coffee drinker. A Griffith University dietitian, Ben Desbrow, proved fresh coffee has wildly inconsistent content by buying 97 espressos, the base unit of coffees, from Gold Coast cafes and analysing the laboratory results. Some coffees contained up to nine times more caffeine than others; from 25 milligrams up to 214 milligrams.

The finding underscores a nightmare that caffeine scientists have long faced when trying to find out whether caffeine is beneficial, detrimental or neutral for, say, cardiovascular disease, cancer or diabetes. Researchers need to be able to measure a population's caffeine consumption as a starting point. But, as Desbrow demonstrated, recalling how many cups of coffee you consume a day is a dodgy and probably useless gauge. This cornerstone problem could be dissuading scientists from the area and leaving coffee addicts in the dark.

And the reason this may be a problem:
It is generally accepted that stress or edginess and other harmful effects of caffeine can kick in after an intake of 400 milligrams a day, so an unsuspecting person drinking three cups of high-caffeine coffee across the day could easily be in the danger zone without realising.
Sounds like caffeine addiction could be a much bigger problem than I would have expected, all depending on where people buy their coffee from.

Oscar irrelevancy

Oscar nominations 2008 in full - Telegraph

As with last year, I couldn't care less about 95% of the movies and actors nominated in this year's Oscars.

I was going to say that it seems a long time since Oscars truly reflected mass audience tastes, but I suppose the year that the last Lord of the Rings movie walked away with everything might disprove that. (Then again, I strongly suspect most people saw it out of obligation to finish the trilogy; not because it was inherently that great a film.)

It would be better for all concerned if the Oscars did not proceed this year; maybe it will actually make people look forward to a year when the nominations might align more with popular taste.

More on mercury in fish

High mercury levels are found in tuna sushi - International Herald Tribune

Hey, whenever I decide there's nothing to blog about, I find a few things in quick succession.

Further to my recent post about mercury in fish, here's an article indicating that it is a real problem even for the relatively small amounts of tuna eaten as sushi:

Recent laboratory tests found so much mercury in tuna sushi from 20 Manhattan stores and restaurants that at most of them, a regular diet of six pieces a week would exceed the levels considered acceptable by the Environmental Protection Agency.

Sushi from 5 of the 20 places had mercury levels so high that the Food and Drug Administration could take legal action to remove the fish from the market. The sushi was bought by The New York Times in October.

"No one should eat a meal of tuna with mercury levels like those found in the restaurant samples more than about once every three weeks," said Dr. Michael Gochfeld, professor of environmental and occupational medicine at the Robert Wood Johnson Medical School in Piscataway, New Jersey

Canned tuna has been recognized as a potential problem for some years too, but these sushi tests were even worse:
In 2004 the Food and Drug Administration joined with the Environmental Protection Agency to warn women who might become pregnant and children to limit their consumption of certain varieties of canned tuna because the mercury it contained might damage the developing nervous system. Fresh tuna was not included in the advisory. Most of the tuna sushi in the Times samples contained far more mercury than is typically found in canned tuna.
The levels of mercury in large fish everywhere seems to be a phenomena that just doesn't attract the degree of public concern that it deserves. (In past posts, I have noted the problem with mercury in dolphins eaten in part of Japan, and in whale meat eaten somewhere else.)

What I don't understand is where the mercury is coming from, and is it too late to do anything about it? And if they have so much mercury in their flesh that we shouldn't eat them, how come the dolphins, whales and fish don't get sick themselves?
