Not your average summer camp

Gaza campers stage 'Schalit abduction' at ceremony | Jerusalem Post

According to Israeli defense officials, more than 120,000 Palestinian children are spending the summer in Hamas-run camps. In addition to religious studies, the children undergo semi-military training with toy guns.

At a recent summer camp graduation ceremony, the children put on a show reenacting the June 2006 abduction of Schalit. Present was Osama Mazini, a senior Hamas political leader, who is in charge of the Schalit negotiations with Israel on behalf of the terrorist group.

The article has a photo of the cute little guys re-enacting the kidnapping of Schalit. (By the way, I assume Schalit has not undergone Stockholm syndrome, otherwise he would have been on display.)

Microbes ‘R’ Us - Olivia Judson Blog - NYTimes.com

I'm not feeling very topical today, so just some more unusual facts from the New York Times:

The typical human is home to a vast array of microbes. If you were to count them, you’d find that microbial cells outnumber your own by a factor of 10. On a cell-by-cell basis, then, you are only 10 percent human. For the rest, you are microbial. (Why don’t you see this when you look in the mirror? Because most of the microbes are bacteria, and bacterial cells are generally much smaller than animal cells. They may make up 90 percent of the cells, but they’re not 90 percent of your bulk.)

A bit of mutilation for a Monday

Sexual mutilation, madness and the media

This appeared a couple of weeks ago in Peter Stothard's blog in The Times: a fairly lengthy account of controversy in the 1860's in England about a London surgeon who did clitoridectomy as a "cure" for mental illness.

His practice was written up in The Times, which brought the issue into the open, and led to an investigation. The anti-clitoridectomy faction of medical opinion won the day.

A remarkable story.

A useful post

Andrew Bolt does one of those useful "remember what they used to say" posts about Labor and "jobs snobs".

He also points us to an article in The Australian about how bad the figures are for the world being able to achieve the goal of 450ppm CO2. It would seem, essentially, that everyone may as well stop pretending it can be achieved.

When your co-worker strips...

...it's probably because he is Japanese, and having to put up with a fairly remarkable government idea:

Takashi Kadokura used to strip down to his underwear when working late because of the heat.

"We couldn't concentrate on our work," said Kadokura, 37, then an economist for Dai-ichi Life Research Institute in Tokyo. "The air conditioning was set at 28 degrees and we weren't allowed to change it."

The experience led Kadokura to question the government's Cool Biz policy, which recommends companies set air conditioners at 28 degrees to reduce carbon dioxide emissions. Kadokura says sweaty offices lead to lower productivity, and estimates the policy reduced economic growth in 2008 by ¥653 billion, or 0.13 percent of the gross domestic product of ¥497.4 trillion

More details in the Japan Times: Cool Biz said to undermine productivity

Changes in Christianity

There are two posts of interest at the First Things blog about the changing demographics of Christianity:

* first, Episcopalians, despite (or, more accurately in my view, because of) their progressive reputation are dwindling. First Things quotes from another blog these figures:

In a historic shift, more people are now attending Assemblies of God churches on weekday nights than worship in Episcopal Churches on Sunday mornings.

Average mid-week evening attendance at Assemblies of God churches is now 756,263, according to the denomination’s official statistics.

Average Sunday attendance, among Episcopalians, is 727,822.

In the past 45 years, Episcopal Church membership has dropped from 3.4 million in 1964 to 2.1 million in 2007. At the same time, the inclusive membership in the Assemblies of God has skyrocketed, from 572,123 in 1964 to 2.9 million in 2008.

* Secondly, this post, looking at world-wide changes in Christianity, contains lots of surprising figures, such as this:

This past Sunday it is possible that more Christian believers attended church in China than in all of so-called “Christian Europe.”...

This past Sunday more Anglicans attended church in each of Kenya, South Africa, Tanzania and Uganda than did Anglicans in Britain and Canada and Episcopalians in the United States combined...

For several years the world’s largest chapter of the Jesuit order has been found in India, not in the United States, as it had been for much of the late twentieth century.

On the same issue, John Micklethwait, editor of The Economist, had been doing the media rounds in the last month or two promoting his recently co-authored book "God Is Back", which argues that religion is indeed catching on in lots of new countries. (I think he views the house church movement in China as particularly big.) There's an interesting, even if not sympathetic, review of the book in the New Statesman.

The toughest job

Readers will recall that I am making my way through the surprisingly enjoyable book "Life and Leisure in Ancient Rome". This weekend, it was the chapter about slavery, and I have to say that I did not realise that things could be as tough as this:

"They were bound to promote their master's welfare at every turn, because there was no limit to the punishment which he could inflict on them if he was dissatisfied; and they were encouraged to preserve his life by the strongest of all imaginable deterrents; if he was murdered, the whole of his slave-household were put to death without even the formality of a trial, on the grounds that, since they had not prevented the murder as they should have done, they were all accessories after the crime. ...

In AD 61, stung by a personal grievance, a slave of the City Prefect Pedanius Secundus killed his master; the whole vast slave household of four hundred slaves was executed..."

The book points out that this prompted a riot in Rome (people were by this time starting to think the law was - literally, I suppose - a bit of an overkill), and that:

"...despite C. Cassius' eloquent protest that society would collapse if the slaves were not killed, a number of senators had doubts and troops had to be fetched in before the executions could take place."

Talk about your hard nosed conservatives!

Things did improve later for slaves, with Hadrian restricting those who could be killed to those slaves near their murdered master at the time of his death.

But the book also makes the point that well treated slaves were often very loyal to their master.

By the time of Christianity, despite the church institutionally accepting slavery, individual Christians often, at the moment of their conversion, freed their slaves. A good way to mark a conversion, I think.

Look to the skies

Consulting with clouds: A clear role in climate change

Interesting story on new research on clouds and their likely future role in global warming. The news doesn't sound great:

Using observational data collected over the last 50 years and complex climate models, the team has established that low-level stratiform clouds appear to dissipate as the ocean warms, indicating that changes in these clouds may enhance the warming of the planet.

Furthermore, this is something that a lot of current models don't show this, apparently:

...most of the state-of-the-art climate models from modeling centers around the world do not reproduce this cloud behavior. Only one, the Hadley Centre model from the U.K. Met Office, was able to reproduce the observations. "We have a long way to go in getting the models right, but the Hadley Centre model results can help point us in the right direction," said co-author Burgman, a research scientist at the University of Miami.

Together, the observations and the Hadley Centre model results provide evidence that low-level stratiform clouds, which currently shield the earth from the sun's radiation, may dissipate in warming climates, allowing the oceans to further heat up, which would then cause more cloud dissipation.

Presumably, poor modelling of cloud behaviour could have something to do with the recently reported study that CO2 alone did not account for anywhere near enough warming at PETM, 55 million years ago. Skeptics took the uncertainty from that study as encouragement. People like me took as more of a sign that we should be uneasy that warming from CO2 could be at the high end of the current estimates due to poorly unstood feedbacks.

Really necessary?

BBC NEWS | Technology | Wireless power system shown off

This wireless electricity technology that's been talked about from time to time looks ready to actually take off.

I don't quite understand why it has appeal: sure, you can do with a few less electricity cables around the house, but get to have many more magnetic fields too.

They are saying magnetic fields are not dangerous to humans. I don't know enough about biology to know, but I would have thought most people would take a cautious attitude towards it.

Besides, I thought magnetised iron had been found not only in bird brains, but human too? (Yep, my memory is correct.) Maybe people who use this system will become completely hopeless at sensing direction (since magnetite in birds was believed to be related to their navigation skills.)

Wasn't there was a Heinlein short story (or novella?) in which the health of the human species was being weakened gradually by wireless power system?

You heard this caution here first, or last, or somewhere in between.

Research for the future

Experiments Show 'Artificial Gravity' Can Prevent Muscle Loss In Space

....researchers at the University of Texas Medical Branch at Galveston have conducted the first human experiments using a device intended to counteract this effect — a NASA centrifuge that spins a test subject with his or her feet outward 30 times a minute, creating an effect similar to standing against a force two and half times that of gravity. Working with volunteers kept in bed for three weeks to simulate zero-gravity conditions, they found that just one hour a day on the centrifuge was sufficient to restore muscle synthesis.

One of the interesting things about long term colonies on the Moon or Mars would be whether the people (or especially, a baby conceived in low gravity) would weaken sufficiently so as to find it impossible to return to Earth.

Maybe just low gravity is enough to provide sufficient muscle tone, but no one will know until we can go there. I imagine mouse or rat breeding on the Moon would be a very interesting experiment.

There was a made-for-TV movie I half watched a few years ago about a Helium 3 mining colony on the moon. In it, a woman fell pregnant, but was spending some time each day in a centrifuge type device to make sure the foetus was used to higher gravity. (I think she was returning to earth to actually give birth.)

It may turn out to have been quite accurate.

Reality fat, and comedy woes

Next on TV: A family of 300-plus folks, heavy girlfriends and, yes, Ruby

Disturbing news of new American reality TV concept:

TLC has ordered six episodes of a show titled, "One Big Happy Family," chronicling the life of an obese North Carolina family: dad, 340 pounds; mom, nearly 400 pounds; and two teenagers, 330 and 340 pounds each.

There's also a overweight dating show on Fox.

Will this trend soon be on Australian TV? Was "The Biggest Loser" an imported concept?

It's all academic to me, I guess, since I don't think there has ever been a reality TV show that I have been able to watch for more than 10 minutes.

The only problem is that surely "reality TV" draws resources away from worthwhile drama, comedy, and other creativity in TV. I mean, with the demise of Scrubs, there is not a sitcom worth watching. (Maybe 30 Rock, which I have never seen due to its odd scheduling here.)

As for the current alleged successes in TV comedy:

Two and a Half Men: a half-clever concept (playing on Charlie Sheen's real life playboy image,) but humour based on wildly promiscuous lifestyles wear thin after a very short time if that is the only joke that exists about a major character. (Having it as a raison d'etre of a more minor character is fine - the whole show doesn't revolve around them.) So I can't warm to this show, and always feel a little queasy when young actors are partaking in double entendre and other low brow humour.

How I Met your Mother: can't get into it. Seems weak and convoluted.

State of the Union: not a sitcom, but Tracey Ullman's latest sketch show. I've always thought she is very talented, with shows that feature a pretty appealing eccentricity. But - she's got too much control now, it seems, and the language and some of the skits are in very poor taste. (We don't really need jokes about ejaculate in a woman passenger's hair, do we?)

The Chaser's War on Everything: haven't cared much for it for a long time, due to its inability to know where to draw the lines between clever, stupid and tasteless. Should have ended about midway last season.

Wind problem for Great Britain

Wind power plan blown off course

The Government was facing a growing credibility gap over green jobs last night as environmental campaigners and trade unionists united to fight the closure of Britain's sole major wind turbine plant.

Only last week, ministers proclaimed a green employment future for the UK involving 400,000 jobs in environmental industries such as renewable energy – yet this week they are declining to intervene over the forthcoming closure of the Vestas Wind Systems plant on the Isle of Wight, with nearly 600 redundancies.

Mars within reach (eventually)

Ion engine could one day power 39-day trips to Mars - New Scientist

Ahem. If people want an idea of what it's like to have been a space enthusiast for the last 43 years, I can tell you that I remember in primary school I once gave a short "topic talk" on the promise of ion engines. This was based on a very detailed book at the local library (in the kid's section, mind you) about the future of space technology. I can still kind of remember the look of the book.

I also remember coming up with a detail about ion rockets which was a bit of a guess, but years later I read something that indicated it was correct.

Mind you, I don't remember anyone in the class room being particularly impressed. I think the teacher's reaction was one of half interested approval, but for all I know she may have thought it was all science fiction.

So, 40 years later the idea is still being talked about as a possibility, and work on them continues at a very slow pace.

Maybe my grandchildren will take a cruise to Mars on a ion rocket, and on the way read this digital evidence of my foresight (and high self regard.)

Travel warning for all male Goth readers

Gulfnews: Sharjah police enforce old law against men wearing accessories

Thirteen-year-old Mohammad was with a group of friends in Al Qasba area when he was reportedly approached by a police officer and taken to the police headquarters. His silver necklace had to go.

Another resident, Jeril Jaison Varghese, says he was in front of the Multiplex in Mega Mall to watch a movie when a CID officer asked him for his identification.

"I was taken to the Sharjah Police office inside the mall by a security guy from the mall. My silver bracelet was confiscated by the CID," he said.

When Varghese asked why his bracelet was being taken away, he says, police said men are not allowed to wear bracelets or any fashion accessories in Sharjah malls even if it is silver and not gold.

Mohammad from Sudan said his 18-year old nephew who came from Abu Dhabi to visit his grandmother in Sharjah was taken last week to the headquarters for wearing a silver necklace.

"The boy was afraid. He was standing in front of his grandmother's house when police took him to the CID. After three hours he contacted us," said Mohammad. Residents said Sharjah authorities should inform people who wish to come here that men must not wear fashion accessories.

Diamond earrings, silver bracelets and necklaces are all verboten for men by law in this corner of the Middle East. Pity that most teenagers don't read the newspaper and don't know about an 8 year old law that they have suddenly decided to enforce. (Pity about tourists too.)

How nice can you make a box?

House in Nagoya by Suppose Design Office

This small house in Nagoya looks almost like an oversized shipping container on the outside, but inside it's really very nice.

One obvious issue though: as many people in comments observe, is it really a good idea to have the toilet separated from the dining room only by glass? Talk about your shy bladders. Maybe when that internal plant grows bigger, you can literally go "behind the bushes" without ever leaving the house.

Someone in comments thinks they can see a curtain rail in the bathroom ceiling, so maybe there is a chance of privacy.

The other practical issues I can see with this design are:

* in summer, so many skylights present a real heat problem, surely.

* with so much internal glass, the owner's had better like having to wiping huge areas with Windex every week.

* it has a fairly typical designer's (and Japanese) disdain for safety about heights. No rails on the stairs, open windows on the upper level overlooking the internal garden. It's like a death trap for small children and drunks. (A very elegant one, but a death trap all the same.)

Fish up, red meat down

Large Study Points to the Brain Benefits of Eating Fish

The study, which included 15,000 people ages 65 and older in China, India, Cuba, Venezuela, Mexico, Peru and the Dominican Republic, found that those who ate fish nearly every day were almost 20 percent less likely to develop dementia than those who ate fish just a few days a week. Adults who ate fish a few days a week were almost 20 percent less likely to develop dementia than those who ate no fish at all.

“There is a gradient effect, so the more fish you eat, the less likely you are to get dementia,” said Dr. Emiliano Albanese, a clinical epidemiologist at King’s College London and the senior author of the study. “Exactly the opposite is true for meat,” he added. “The more meat you eat, the more likely you are to have dementia.” Other studies have shown that red meat in particular may be bad for the brain.

The story, however, notes that this was an observational study, not a randomized clinical trial, so maybe the figures are not as reliable as they could be.

If they believe it is the Omega 3 that is the protective element, is it so hard to do the proper randomized trial on that as a supplement? Or has it already been done?

Well, that just took a quick Google to find that some studies have been done with Omega 3 as a supplement, and the results are very mixed. (Although it looks to me like the studies were done on people who already have a problem. I guess it is very hard to randomly pick a bunch of 60 year olds, get them to take a supplement for years, and see what protective effect it has.)

Back to the drawing board

Death knell for NASA's Ares rockets? - New Scientist

Quite a detailed explanation here of a major safety issue for the planned Ares rocket. (It's very hard to work out how to get the crew safely away from an exploding first stage.)

Update: I see Zoe Brain had a good post about this before me, which included a very spectacular video of a solid rocket explosion that is well worth watching.

Good sense

PM Kevin Rudd told nuclear is best hope by Rio Tinto | The Australian

MINING giant Rio Tinto has urged Kevin Rudd to immediately begin work on a regulatory regime allowing use of nuclear energy in Australia, arguing the viability of energy alternatives has been dramatically overstated.

The company has advised the government to consider "every option" for power generation because its pledges on reducing carbon emissions and using renewable energy will expose industry and consumers to huge increases in their power bills.

And it says that overly optimistic assumptions on the viability of alternatives such as wind and geothermal power, as well as so-called clean coal technologies, have created a "false optimism" which the government must challenge by commissioning new research.

Of course, the first challenge is to get the Labor Party to change its anti nuclear policy:

....Resources Minister Martin Ferguson emphatically rejected the need for nuclear power generation in Australia, insisting that the nation had ample resources of cheap coal and gas to meet its energy needs.

Mr Ferguson told The Australian he saw no reason for next week's federal Labor Party conference to review the party's prohibition on nuclear energy.

I can't imagine Labor changing its policy any time soon, and even if it did, election predictions on Insiders last week were that the Greens will hold the balance of power in the Senate next time, whether or not there is a double dissolution.

The Greens will doom us if the Senate's co-operation is needed to ensure nuclear power. (I presume it is for the new "regulatory regime".)

Vote Coalition for sensible long term nuclear policy!

Liddle on Dubai

Sordid reality behind Dubai's gilded facade - Times Online

First it was The Independent, now the Times has run a lengthy, detailed article absolutely ripping into Dubai.

It's by Ron Liddle, so there is humour in there too, but he is clearly genuinely appalled at every aspect of the place.

Liddle makes it clear that the most offensive thing is that it is built by appalling treated immigrant labour, about which he writes:

The Indians rioted too last year, but were forced back to work by water cannon. In the year 2005 alone, the Indian consulate estimated that 971 of its nationals died in Dubai, from construction site accidents, heat exhaustion and — increasingly — suicide. The figure for suicides the next year alone was more than 100. The Emiratis were, to give them credit, appalled by this figure, so they asked the consulate to stop collating the statistics.

The whole article is worth reading.

Convenient memory lapse

Neighbour watches woman prepare syringes in front of children: inquest

The neighbour of a Sydney woman whose child died of a methadone overdose told police he watched her prepare syringes full of amphetamines in front of her children on several occasions, an inquest has heard....

In the statement, taken in May 2006, the man - who cannot be named for legal reasons - described being at the woman's home on five occasions sharing $100 worth of amphetamines with her partner and his own partner.

"I have seen [the woman] divide the powdered drugs up and melt her half in a spoon and then put it into two separate syringes. This all occurred in [her] home," the man said in his statement.

"I remember seeing both the two girls running around the house when we used to divide the drugs up."

The man said he often saw "lots" of syringes around the family's home.

But before the coroner today:

...the man could not recall much of what he said in his statement and said he did not know why he had said it.

"Compared to other kids, they were excellent ... always well dressed," he said.

"[The boy] was always smiling.

Drug users are such a likeable bunch.
