Careful with the crayfish

Another story about (possible) dangerous food in China:

....dozens of people in Nanjing were hospitalized with strange symptoms of unbearable muscle pains after eating crayfish since July. The doctor’s diagnosis was rhabdomyolysis (the destruction or degeneration of muscle tissue) serious cases even cause kidney damage. The speculation was that the “shrimp washing powder” (洗虾粉) which was popularly used by the sellers to make the crayfish look spanky fresh and clean could be the root cause.

Inconstant universe

It seems that there is new evidence that the fundamental constants of the universe are not so constant:

Today, John Webb at the University of South Wales, one of the leading proponents of the varying constant idea, and a few cobbers say they have new evidence from the Very Large Telescope in Chile that the fine structure constant was different when the universe was younger.

But get this. While data from the Keck telescope indicate the fine structure constant was once smaller, the data from the Very Large Telescope indicates the opposite, that the fine structure constant was once larger. That's significant because Keck looks out into the northern hemsiphere, while the VLT looks south

This means that in one direction, the fine structure constant was once smaller and in exactly the opposite direction, it was once bigger. And here we are in the middle, where the constant as it is (about 1/137.03599...)...

The implication from Webb and co's data is that the fine structure constant is continuously varying throughout space and is merely fine-tuned for life in this corner of the cosmos: the universe's habitable zone. Elsewhere, presumably well beyond the universe we can see, this constant is entirely different.

That's likely to put the cat among the pigeons.

If the work holds up, this is big news.

Heightened reality

The 100 year old colour photos of pre-revolution Russia which Tim Blair linked to yesterday really are worth looking at. It's amazing how seeing history in crisp colour makes the past feel not such a distant country after all.

Unusual help

Slate has an article about a book written by a guy who grew up with parents who were both Jungian psychotherapists. Apparently, most people who hear this assume he will have been driven mad by his parents psychoanalyzing everything, and when you read this bit of parental help the author received, I don't really wonder why:

Toub's parents .... actively brought their Jungian practice into their parenting technique. There was a lot of dream analysis in the Toub household, of course, and also exercises in the Jungian technique of "active imagination," which Toub explains is "deliberately exploring one's imagination and fantasies by … acting them out verbally or physically to read the message that one's unconscious is trying to communicate." In one memorable scene, Toub's mother encouraged him to "be" an erection in order to help him get over a bout of teenage impotence. To accomplish this, she took young Micah to a local park and had him pretend to be his own boner. "Your name is not Micah, you are not a human being," she told him. "You are an erection. What words come into your head?" He visualized himself as a "victorious penis," running around the park triumphantly.[*] Laugh away, but the treatment worked: Micah is no longer plagued by an uncooperative member.

Apart from the therapy, I am surprised by two things: a. a teenager can suffer impotence? and b. a teenager would tell his parents he is suffering impotence.

Update: * I also get the feeling the exact same visualization was being used by Tony Abbott to try and win the election.

Meaning unclear

For no reason I can think of, this morning, while walking to the car, the theme music for Gigantor came to mind. I am hoping that this later proves to be a meaningful co-incidence; but preferably not by a giant Japanese remote controlled robot appearing in my city.

Pebble Bed returns?

Pebble Bed Advanced High Temperature Reactor at UC Berkeley – low cost nuclear?

Well, I haven't heard anything about the South African pebble bed reactor development lately. (Probably, I learn right now, because it has definitely gone belly up.)

Yet a new type of pebble bed reactor is discussed at Brave New Climate: one that uses molten salts as a coolant. Reporting on a visit to UC Berkeley:

So, back to Per’s lab. He has various engineering models set up to test movement of TRISO pebble fuel through a fluoride salt coolant, whereby the pebbles are inserted in the inlet pipes and rise up through the reactor module over time, and then are put back through 5 or 6 times. This allows for very high burnup — exceeding 50 %, high power density due to the heat capacity of the liquid salt, and high temperatures thanks to the durability of the pebbles. This is a big (potential) advantage over the current Pebble Bed Modular Reactor technology (PBMR), because in that design, the gas coolant has a very low power density. He’s flipped the problem on its head. The reactor also has various inherent safety design features, such as control rods that sink naturally in response to elevated coolant temperature, thereby passively regulating reactivity. Very safe!

Of course, this does not sound as modular as the South African design was intended to be, but it is still being explored as means of making cheaper nuclear designs than the current designs. (The article explains that the cost of new nuclear is still providing prohibitive for its expansion in the US.)

So it's a case of the pebble bed is dead...long live the pebble bed!

At least it's amusing

I've said this on another blog, but repeat it here.

Regardless of who ultimately forms government, I'm finding it very amusing to watch Tony Abbott, whose promoters loved him for his aggressive approach to Opposition (he brought down Kevin Rudd! He united his party! He didn't bite a Labor opponent during the election campaign, like everyone thought he might!) having to present a new face - conciliatory Tony - due to having to deal with independents to gain government.

So in recent days it's all "yes, Parliament is unnecessarily confrontational, isn't it" and "sorry Andrew for the way the last government I was in said you were nuts". Looks distinctly unlike the "real Tony" to me, but we haven't heard any of that from the "how many Julia's are there" crowd yet.

Some time ago I jokingly noted that Tony might do better as a eunuch, as some academic had suggested they had historically (in many societies) been able to play an important role in government by not being so distracted by testosterone. Seems the joke had more truth in it than I realised at the time.

Attack of the flash drive

This is pretty interesting. An enemy attack could be bound up in something as simple as a USB flash drive inserted in a laptop on the other side of the world:

The most serious cyber attack on the US military's networks came from a tainted flash drive in 2008, forcing the Pentagon to review its digital security, a top US defense official said Wednesday.

The thumb drive, which was inserted in a military laptop in the Mideast, contained malicious code that "spread undetected on both classified and unclassified systems, establishing what amounted to a digital beachhead, from which data could be transferred to servers under foreign control," Deputy Defense Secretary William Lynn wrote in the journal Foreign Affairs.

The code was placed on the drive by "a foreign intelligence agency," Lynn wrote.

"It was a network administrator's worst fear: a rogue program operating silently, poised to deliver operational plans into the hands of an unknown adversary."

Previous media reports speculated that the attack may have originated from Russia.

Mouse guard needed

Saudi Arabia is seeking to stop just any old mufti from issuing "absurd fatwas" by decreeing that they can only be issued by the Council of Senior Religious Scholars.

An example of an absurd fatwa:

Shaikh Mohammad Al Munjed, a Syrian scholar living in Saudi Arabia, said that Mickey Mouse should be killed because he is a mouse and mice are considered unclean in Islam.

I take it that Disney Riyadh won't be opening any time soon.

Wartime disaster noted

World War II was so chock full of dramatic death and disaster, there are still examples of it which I haven't heard of before. From The Independent, noting in a obituary the death of one of the survivors:

Wednesday 23 August 1944 began like any other day in the sleepy Lancashire village of Freckleton. Situated on the banks of the River Ribble, once the traditional haunt of smugglers, during the Second World War it played host to a large contingent of American airmen, based mostly at the neighbouring Warton aerodrome.

At its heart lay Holy Trinity primary school where 176 children, many of them evacuees, were in their second day of a new term....

At 10.30am, an American Liberator Bomber 42-50291 took off from Warton on a routine test flight. Eleven minutes in, a huge explosion, thought to have been sparked by a bolt of lightning, tore the huge plane apart. Large parts of the fuselage rained down on the village, hitting the school and a neighbouring snack bar. In the ensuing inferno, 61 people were killed, including 38 members of that infant class; it was the greatest loss of civilian life outside London during the Second World War.

Science additions

I've added two science blogs to the roll: Erin, who is doing science communication but has much better hair than Bernie Hobbs, has started "Buzzing Universe", at which she hopes to concentrate on controversy in cosmology. What a good person to know.

I've also added Backreaction, the long running blog of physicist Sabine Hossenfelder. She's always been good to read, and seems a lot less of a culture warrior than many physicist bloggers (like those at Cosmic Varience, who just love getting upset with religion all the time.)

Rent a poor womb

A disturbing article is here at Slate about how popular the use of surrogacy in India has become as a way for poor, often illiterate, women to make a large amount of money:

It is not uncommon for surrogates to authorize contracts with a thumbprint as opposed to a signature because they are illiterate. Even those who are literate often aren't able to read the contracts, which tend to be written in English. Lack of technological understanding among rural Indians also breeds misconceptions about surrogacy. Many, for example, thought that it would be necessary to sleep with another man in order to conceive. Even the pricing structure of surrogacy perpetuates social inequality: Many religious Indian surrogacy clients would prefer for their child to be birthed by an upper-caste brahmin, so high-born surrogates can get paid up to double.

And how about this as an example of the appalling excuse making that some in the reproductive technology business undertake:

The country is romanced by the idea of selling human capital as its next great commodity. So surrogacy resonates not as an old problem of exploiting the poor but as an inevitable part of the "new India," where the locals provide much needed services for the new global economy. This kind of forward-thinking economic liberation dovetails with an ideology of personal freedom. "I think women should be free to choose what they do with their bodies," says Dr. Aniruddha Malpani, a fertility specialist in Mumbai. "We shouldn't treat them as stupid just because they are poor."

Going back a few months, I never got around to posting about the Melbourne woman who was off to Thailand to have sex selecting IVF to get a girl. I doubt she had much public sympathy: oh, except probably from some in the IVF industry. As was noted in Eureka Street in April, before that Melbourne mother's case was publicized:

In recent weeks, several reports have appeared in the media that Australia's ban on couples using IVF to choose the sex of their children for social reasons or to balance their families might soon be lifted.

Most stories quoted 'IVF pioneer' Professor Gab Kovacs, who is said to be 'leading the charge' or 'leading the lobby'. A number of other fertility doctors are also involved.

This seems to be a pre-emptive attempt to sway public opinion. The inquiry has not yet commenced. And supporters of this view know that many of us are not comfortable about parents choosing the sex of their children. So ahead of time, they're trying to change our minds.

Your urine powered future

Lots of jokes to be made at the expense of this article about research into using urine to generate useful amounts of electricity.

The problem with helium

The Independent explains how the world's helium is running out:

Scientists have warned that the world's most commonly used inert gas is being depleted at an astonishing rate because of a law passed in the United States in 1996 which has effectively made helium too cheap to recycle.

The law stipulates that the US National Helium Reserve, which is kept in a disused underground gas field near Amarillo, Texas – by far the biggest store of helium in the world – must all be sold off by 2015, irrespective of the market price.

The experts warn that the world could run out of helium within 25 to 30 years, potentially spelling disaster for hospitals, whose MRI scanners are cooled by the gas in liquid form, and anti-terrorist authorities who rely on helium for their radiation monitors, as well as the millions of children who love to watch their helium-filled balloons float into the sky.

Further down, though, the article says all the helium may be gone within 100 years.

So how much should a helium balloon cost?:

Professor Richardson believes the price for helium should rise by between 20- and 50-fold to make recycling more worthwhile. Nasa, for instance, makes no attempt to recycle the helium used to clean is rocket fuel tanks, one of the single biggest uses of the gas.

Professor Richardson also believes that party balloons filled with helium are too cheap, and they should really cost about $100 (£75) to reflect the precious nature of the gas they contain.

Soon it'll be hydrogen balloons for the kiddies, but only if their parents don't smoke.

Back to science

Here’s a good article on the very surprising (apparent) finding that solar neutrinos – or another mystery particle from the sun - affect radioactive decay on Earth.  (I’m sure I mentioned this here before a long time ago.)  Much work remains to be done, though.

Contrainception

I went and saw Inception yesterday, partly for the rare treat of seeing a well reviewed adult movie, and partly to see whether my hunch was right that the weekend election was a dream within a dream. I'm leaning to the theory that soon Malcolm Turnbull will wake up and resume his rightful place as Prime Minister.

Anyhow, I have to say I was pretty disappointed.

Christopher Nolan's career has coincided with my young child raising years, so I still haven't seen his well regarded Momento or even The Dark Knight. But if Inception is any guide, it certainly appears he doesn't do ordinary human emotion very well. It's flashy film making with money and CGI effects galore, but its over-riding fault is how very cold [update: probably more accurate to say "unengaging", as did the WSJ review] it feels at an emotional level. In that respect, it seemed rather like a Kubrick effort, but lacking that director's more careful pacing and powerful set piece imagery which usually more than compensated for the artificial quality of much of the acting.

There was one element that came close to feeling emotionally real and being an interesting plot point - the DiCaprio character's unresolved guilt over the fate of his wife - but the details of it were revealed far too late in the film, and not resolved in any especially memorable way.

Here's a list of other problems I had with it:

* no wonder it's said to have taken 10 years to write. It's supposed to be an adage of good filming making that it is better to show character and story rather than have protagonists explaining it, yet this would have to be the most "explained" cinema event since An Inconvenient Truth.

* talk about your cursory attempts to portray a new technology. Group dreaming involved a briefcase sized device with what seemed to be intravenous lines into the wrist, although even that was not so clear. The drugs involved seemed to come from a backyard operation. Come on, if the participants had a least a electronic mind wave reading skull cap on, it would have had some vague plausibility, but just linking up via the wrist?

* the action scenes were, by and large, just poorly directed, with editing that was too choppy to tell what was really going on, and who was in danger. And because a lot of the figures being shot or crushed were merely dream characters, there was not the same sense of danger that you get from "real life" action.

* the near climatic action around a snow bound fortress looked extremely similar to the snow chases and gunfights we've seen many times in James Bond films. Why did Nolan think this would look particularly interesting? It was actually hard to tell who was who during parts of this segment.

I would guess that Nolan was heavily influenced by Jungian ideas on the subconscious and dreaming, which makes his lack of emotional involvement all the more puzzling, given my impression that Jung was a "warmer" character with less of the cool intellectual approach of Freud.

This is a film that would have been better served by a lighter touch, a shorter length, and director better with emotion. People like to complain about Spielberg's sentimentality, but the way he dealt with adult emotional material in the very serious science fiction of AI and Minority Report left you feeling something at least, unlike this effort.

It also reminded me of another film dealing with fights inside dreams - Dreamscape from the 1980s. I remember very little of its plot now, but do recall enjoying it as a bit of a romp, and that's about as much as you should expect from this implausible type of science fiction. (Amusingly, on the question of originality of Inception, I have just read the Wikipedia entry I linked to above, which notes that the central idea is very similar to the plot of an Uncle Scrooge comic! I see the Kubrick similarity has been noted by others too.)

Gee, now that I have put down my issues with it, it sounds like I really hated it. That's not quite true either, but as you can see I spent a fair bit of time thinking about why it wasn't working for me. I also tend to react more strongly against a very big budget film that I consider a failure than a more modestly scaled one, for the obvious reason that it feels more of a waste when it has sucked money away from (say) 3 smaller scale examples of science fiction which could well have been more enjoyable.

So maybe that's it for my adult movie viewing for another year. I'm half tempted by "Salt," but it's hard to believe I could really like an Angelina Jolie film.

Update:   It's me, from the future, finding that I enjoyed it more on the second viewing.  Huh.

Election comment

Sad accident

As far as horrible hospital accidents go, this one is spectacularly bad:

Grace Wang's spinal canal was injected with powerful antiseptic instead of anaesthetic, in what should have been a routine epidural to ease the pain of her first child's birth.

The Herald understand the two substances had been transferred to separate metal dishes on the sterile table, contravening the standard practice of drawing them directly from their packaging into a syringe to avoid confusion.

The devastating medical mistake - inconceivable in its magnitude - has poisoned her nervous system, leaving the 32-year-old distressed, confused, in shocking pain and unable to walk or even sit.

How inconvenient

Nature reports:

The capacity of plants to act as a carbon sink could be on the decline.

As global temperatures have risen in recent decades, the amount of atmospheric carbon being converted into plant biomass has increased in step. However, in a paper published today in Science, ecologists Maosheng Zhao and Steve Running at the University of Montana in Missoula report a surprising reversal of this trend over the last decade, despite its having been the warmest on record.

The reason appears to be drier conditions in the Southern Hemisphere.

Limited responsibility

Well that's good. Due to a change in my electorate's boundaries, I am now living in what appears to be one of the safest Labor seats in Brisbane. Previously, I was in a seat that swung from side to side, and my vote actually mattered. Given the appalling choices this election, I kind of like the sensation of irrelevancy, at least for the moment.

The Senate remains a problem. The Greens have exactly one policy I support, but it's an important one - a carbon tax.

Both Labor and Liberal say there will be no carbon tax. Brown thinks he can force one through, and he supports a mining tax, but wants to increase the amount that can be gained from it. I generally support the mining profits tax, but don't really trust Brown's fiddle with it.

The Coalition really can't be trusted on environmental issues while there are under the sway of Abbott and his supporters.

The likely line up of independents seems very up in the air, except I think everyone expects the slightly loopy Fielding to go. I don't know anything about independents running in Queensland.

I think it is looking like, in the mix, I would probably be best off supporting Labor in the Senate, while at the same time hoping Brown wins eventually on the carbon tax.

UPDATE: courtesy of Antony Green's election site, I now have a good idea of what's going on in the Senate at Queensland level. Hey, Barnaby Joyce is up for re-election. As well as George Brandis.

Joe Ludwig is also on the card for Labor.

The game of who to put last is always a challenge. This time, it looks like a contest between both of them in the Climate Sceptics Party and the perpetual protester Sam Watson of the Socialist Alliance.

What do you know: the Australian Democrats still exist! I expect they hold their conferences in one of the meeting rooms at the local Council library.

Well, this is going to take some studying.
