ScienceDaily: Iron Critical To Ocean Productivity, Carbon Uptake
The story above notes:
A new study has found that large segments of the Pacific Ocean lack sufficient iron to trigger healthy phytoplankton growth and the absence of the mineral stresses these microscopic ocean plants, triggering them to produce additional pigments that make ocean productivity appear more robust than it really is.
As a result, past interpretations of satellite chlorophyll data may be inaccurate, the researchers say, and the tropical Pacific Ocean may photosynthesize 1-2 billion tons less atmospheric carbon dioxide than was previously thought. Global ocean carbon uptake is estimated at 50 billion tons, so the reduction in the estimate of the uptake is significant -- about 2 to 4 percent.
It doesn't talk directly about the idea of fertilizing the ocean with iron as a way of decreasing CO2 in the atmosphere, but surely this possible anti global warming method should start attracting more serious attention again soon.
I thought I mentioned this idea before here, but can't find the post now. Anyway, I have found a detailed Wikipedia entry about it which (while apparently written from the "pro" side) does explain some of the possible "cons" too.
Certainly sounds worth serious consideration (more so than shooting sulfur into the high atmosphere.)
UPDATE: Blogger search is obviously not working well at the moment, for some reason. Here's my earlier post where iron fertilization got a mention.

Conservatism and Islam, again
It's a culture guaranteed to cause a clash - Opinion - smh.com.au
Miranda Devine makes pretty much the same point as someone in The Guardian recently. (I posted about it here.)
That is, Muslim reluctance to "blend in" to Australian society may be partly put down to Australian values (in terms of sexual behaviour, especially amongst the young) taking somewhat of a dive in recent years.
Given my revulsion of all things "Big Brother" (and the puzzling idea of "raunch culture" as being some semi-legitimate form of feminism,) I have some sympathy to the argument.
As I said in the previous post, one would think that the political consequence could be that conservative parties get the Muslim vote. But the conservatives don't seem to play the politics of it the right way. (Or they simply figure the Muslim vote is not worth worrying about given the population size here.)
All very interesting.

The Empire staggers on
The Japan Times Online - Princess Kiko gives birth to a boy
So, finally there is a male grandchild for the Emperor in the Japanese royal family, so the pressure is off Crown Princess Masako to have to have another child. (Her story of stress caused by marrying into a suffocating royal lifestyle is a bit like that of Princess Diana; apart from Masako being academically very smart, successful at a challenging career before marriage, and having a husband who supports her still. OK, almost no resemblance at all really.)
A brief history of the problems caused by having only male heirs to the emperor is set out in this article. Some extracts:
Emperor Meiji (1852-1912) had no male heir with his wife but had 15 children, including five males, with five concubines. Of the five, four died before reaching adulthood, and the one who survived became emperor.
Here's a photo of Meiji. Doesn't look too happy; maybe choosing which concubine to sleep over with gets you down. (Or maybe it's just that it wasn't fashionable in that century to smile for photos.)
Back to the article:
But Emperor Hirohito (1901-1989), known posthumously as Emperor Showa, refused to have a concubine, which led to the postwar abolition of the system. According to Otabe, Emperor Showa wanted to have a close family atmosphere such as might be found in a Western royal family.
And how's this for a let down in your status:
Soon after Japan's 1945 defeat in World War II, 11 families on the collateral line, which served as a safety net to produce male heirs for the Imperial family, lost their Imperial status and became ordinary citizens.
I wonder what happened to those families. Down to the unemployment office?

Australian academics need not apply
BBC NEWS | Middle East | Iran's liberal lecturers targeted
From the above:
Iranian President Mahmoud Ahmadinejad has called for liberal and secular university lecturers to be removed.
He told a group of students that they should organise campaigns to demand that the liberal teachers be sacked.
Mr Ahmadinejad said it was difficult to alter secular influences that had been in place in Iran for 150 years, but added that such a change had begun.
The move echoes campaigns of the 1980s, when hundreds of liberal university teachers and students were sacked....
Last year, an ayatollah was appointed to run Tehran University, sparking protests by students.

Scaring the scientists
Scientists angered by telephone telepathy study - Britain - Times Online
A fascinating story from the Times about scientists being upset that pro telepathy research was presented at a science forum without adequate scepticism tagging along.
I like this bit in particular:
Sir Walter, a geneticist and cancer researcher, said: "I’m amazed that the BA has allowed it to happen in this way. You have got to be careful not to suppress ideas, even if they are beyond the pale, but it’s quite inappropriate to have a session like that without putting forward a more convincing view."
The "more convincing view" is presumably that telepathy is obviously impossible.
Read the article for details of the research. It's interesting.

More scepticism on emissions trading
Emissions trading is not the answer - Opinion - theage.com.au
Four Corners last week was all about this too, and there are many small "eco" companies in Australia making money out of trading schemes that critics say are of dubious efficiency.
As with wind power, I suspect that the true effect of such schemes is to give false confidence that something effective is being done.

One question
BBC NEWS | Health | Autism risk linked to older dads
This article indicates that the rate of autism in children rises quite sharply when the father is over 40.
This seems an easily identified trend. Why is it only coming to attention now?

On conservation and conservatism
Niall Ferguson: Conservative Doesn't Mean Anti-Conservationist - Los Angeles Times
This column makes some valid points:
The idea that there is something fundamentally unconservative about protecting the environment is, of course, a canard. At the very core of British conservatism since the time of Benjamin Disraeli has been a romantic reverence for the land and a desire to mitigate the damage done by industrialization. It was Marx and Engels who sneered at "the idiocy of rural life." It was Lenin and Stalin whose mania for smoke-belching steelworks turned huge tracts of Russia into toxic wastelands.
It's worth reading it all.

More Adams rubbish
Hero to pols who were left right out | Phillip Adams | The Australian
Phillip Adams has yet another reality challenged column in the Australian today.
He has repeated the theme many times recently: that John Howard's Liberal Party has become solidly right wing, not the "broad church" of old. He also claims that, unlike in the 1960's, there is no cross party co-operation or friendships any more.
Nice theory, but only if you ignore the following examples:
* Howard withdrew his recent migration law changes to avoid the defeat they obviously faced because of the number of Libs (and probably National Barnaby Joyce) would made it clear they would not vote for it.
* Liberal women are not shy of supporting their own legislation for particular "womens' issues" such as the availability of the "abortion drug" and on stem cell research.
* Warren Entsch, of all people, speaks out on gay law reform all the time. (Although it is clear that there is no strong move to support gay marriage type laws in the Liberals.)
* It is clear that there still are cross party friendships, if you watch Sunrise and see the amiable exchanges every week between Kevin Rudd and Joe Hockey. (They also did the Kokoda track together recently.) I get the feeling that Lindsay Tanner might have the respect and (possibly) friendship of a few on the other side as well. It was pretty clear that Christopher Pyne and Mark Latham were friendly enough at a personal level when they used to do their Lateline stuff. I recall Jacki Kelly talking recently of inviting Labor women to some private party of hers.
Actually, I have found it encouraging that polite and friendly personal contact across the parties appears to have been a feature of the current government.
Adams seems not only wrong about this, but quite hypocritical, in that his great political hero Paul Keating gave every appearance of a politician who could in no way tolerate having a personal friendship with someone from the other side. (And who from the Liberals would want to be be close to him, given the highly personal and nasty character of his parliamentary attacks.)
Give it up Phil, this is a stupid argument.

Steve Irwin and the speed of Wiki
Steve Irwin - Wikipedia, the free encyclopedia
Steve Irwin's unusual death was reported here (Brisbane) at around 2.30pm. It looks like Reuters and AP reported it after 4 pm. It is now 4.35 pm and his Wikipedia entry is up to date, referring to him in the past tense, and giving some detail about his death.
Looking at the history of his entry, there have been many people checking and posting today following news of his death.
History gets written very quickly these days.
As for his death, everyone's reaction on talkback radio here goes like this: "a stingray can kill you? I mean, I knew they could sting and hurt, but kill you?"

Mao's reputation continues its dive
China | Big bad wolf | Economist.com
This is a short review of a new book that continues the revisionism of Mao's reputation (in a downwards direction.) This latest book sounds more scholarly and less obviously partisan than the recent one co-authored by Jung Chang. (Not that I have read it either.)
From the article:
The heart of the book is a detailed chronicle of how Mao cynically twisted ideology and manipulated those around him, setting off hysterical and murderous attacks on everything from Confucian morals and bourgeois culture to intellectuals, “capitalist roaders” and “class enemies”.
Using sources that range from official party and government documents to letters, diaries and interviews with surviving participants and victims, the authors document the orders that went out, the mayhem that resulted and the fear it all struck in the hearts of people across the country. And it is chilling stuff. In August and September of 1966, for example, as thousands were being murdered in Beijing, Shanghai and elsewhere, Mao put out the word that the police were not to interfere. Faithfully relaying Mao's instructions to the Beijing police force, the public security minister assured them that, “After all, bad persons are bad, so if they're beaten to death it is no big deal.”

Medical marijuana wars

Also from TCS, an article about the "medical marijuana" wars in the USA.
This tactic (of encouraging a limited legalisation of the drug for medicinal purposes) has not been promoted strongly in any jurisdiction in Australia, as far as I can recall. This article confirms, from a medical point of view, why it is a dubious thing to do.

An odd comparison
Martyrs' widows wait outside doors to paradise - World - theage.com.au
This short story about how Hezbollah looks after the widows of "martyrs" in Lebanon contains this:
The community believes martyrs go directly to heaven and their wives are venerated because of their sacrifice. "The wife of a martyr is like Jennifer Lopez to us," said Mohammed Husseini, spokesman for Hezbollah's Martyrs' Association illustrating how widows are admired.
Well, perhaps "Paris Hilton" would have been a less apt comparison, but only just.

About Iran and Iraq
Crime boss brokered nuclear-delivery missile sale to Iran - Sunday Times - Times Online
Further to the concerns about Iran:
THE British government was warned more than two years ago that Iran had illegally acquired a missile system capable of carrying nuclear warheads.
It has emerged that a foreign government delivered the warning to Britain in early 2004.
Separately, it has been disclosed that the system was sold to Iran by a former senior member of the Ukrainian security service. The deal was brokered by an organised crime boss and, it is feared, contributed to the Iranian nuclear programme that is now the subject of an international confrontation.
The Times report also notes this:
It has also emerged that in 2004 the Ukrainian government was investigating the transport of weapons from Iraq to Syria and Iran before the war to topple Saddam Hussein.
I still suspect that the complete story of WMD in Iraq is not yet known.

Modern annoyances
Here's a few things I have been saving up to complain about:
* It seems impossible to buy a simple set of plain Lego blocks anymore. (Duplo, yes, but not older kids' basic Lego.) As anyone with children is probably aware, Lego seemingly went totally "themed" many years ago, as if a corporate decision was made that all kids' imaginations must come prepackaged. I'm sure I read somewhere in the last year or two how the Lego company was not doing well. Here's a tip: stop paying for movie tie-in's and overly specialised fiddly pieces and start selling basic sets again. I could live with the little figures (although they do sully the "purity" of the Lego of my childhood,) if basic kits could be found again.
* A pharmacy I was in recently was selling "Hopi ear candles". If I ruled the world, there would be some minimum standard of vague utility for what a pharmacy could sell, and Hopi ear candles would never reach that threshold.
* The twee obsession that ABC Radio National listeners have with fonts irritates me. The Saturday morning show recently did a segment on Microsoft changing the font for (I think) Outlook, and sure enough the following week the host noted how much response that segment received. Oh for God's sake. If you are 95 and live alone on a mountain, maybe an undue interest in default fonts is half justifiable. If you are under 50 and you are worrying about default fonts, you really, really need another interest in life.
* Talking about fonts reminds me: I still occasionally find people who still think Wordperfect stopped at DOS version 5.1. In fact, the Windows based versions are up to X3, which is what they named version 13 in order to avoid the unlucky number. Ironically (if that is the correct use of the word for this example), this latest version lets you run it in DOS 5.1 emulation.
It drives me crazy when I have to sometimes use Word instead of WP. My long held belief that formatting anything in WP is always easier than in Word (which continually tries to guess my intention and 9 times out of 10 gets it wrong) seemed to have been confirmed this week when I showed a Word only user how to do indents and edit codes in WP. He seemed genuinely surprised, and I am sure this could be true of many Word users if only they had exposure to WP.
By the way, I do not own shares in Corel.
