DNA trying to tell us something

Synthetic double-helix faithfully stores Shakespeare's sonnets 

This was a surprising story:

A team of scientists has produced a truly concise anthology of verse by encoding all 154 of Shakespeare’s sonnets in DNA. The researchers say that their technique could easily be scaled up to store all of the data in the world.

Along with the sonnets, the team encoded a 26-second audio clip from Martin Luther King’s famous “I have a dream" speech, a copy of James Watson and Francis Crick’s classic paper on the structure of DNA, a photo of the researchers' institute and a file that describes how the data were converted. The researchers report their results today on Nature’s website¹.

The project, led by Nick Goldman of the European Bioinformatics Institute (EBI) at Hinxton, UK, marks another step towards using nucleic acids as a practical way of storing information — one that is more compact and durable than current media such as hard disks or magnetic tape.

Here's the  most amazing part:

DNA packs information into much less space than other media. For example, CERN, the European particle-physics lab near Geneva, currently stores around 90 petabytes of data on some 100 tape drives. Goldman’s method could fit all of those data into 41 grams of DNA.

 Lots more detail of how it is done is in the article.  As to its potential long term value:

Goldman adds that DNA storage should be apocalypse-proof. After a hypothetical global disaster, future generations might eventually find the stores and be able to read them. “They’d quickly notice that this isn’t DNA like anything they’ve seen,” says Goldman. “There are no repeats, and everything is the same length. It’s obviously not from a bacterium or a human. Maybe it’s worth investigating.”

I wonder if this means there might be a short to medium length message put there by my Creator for use at about this time in history.  "Don't buy Betamax" maybe*.
 
Has science fiction ever covered this?  The nearest I can think of is the ending of Carl Sagan's "Contact", where a message is found hidden inside of Pi.

Maybe built that way?

Chameleon pulsar baffles astronomers

An international team has made a tantalizing discovery about the way pulsars emit radiation. The emission of X-rays and radio waves by these pulsating neutron stars is able to change dramatically in seconds, simultaneously, in a way that cannot be explained with current theory. It suggests a quick change of the entire magnetosphere....

Pulsars are small spinning stars that are about the size of a city, around 20 km in diameter. They emit oppositely directed beams of radiation from their magnetic poles. Just like a lighthouse, as the star spins and the beam sweeps repeatedly past the Earth we see a brief flash.

Some pulsars produce radiation across the entire electromagnetic spectrum, including at X-ray and radio wavelengths. Despite being discovered more than 45 years ago the exact mechanism by which pulsars shine is still unknown.

It has been known for some time that some radio-emitting pulsars flip their behaviour between two (or even more) states, changing the pattern and intensity of their radio pulses. The moment of flip is both unpredictable and sudden. It is also known from satellite-borne telescopes that a handful of radio pulsars can also be detected at X-ray frequencies. However, the X-ray signal is so weak that nothing is known of its variability.

To find out if the X-rays could also flip the scientists studied a particular pulsar called PSR B0943+10, one of the first to be discovered. It has radio pulses which change in form and brightness every few hours with some of the changes happening within about a second.

Dr Ben Stappers from The University of Manchester's School of Physics and Astronomy said: "The behaviour of this pulsar is quite startling, it's as if it has two distinct personalities. As PSR B0943+10 is one of the few pulsars also known to emit X-rays, finding out how this higher energy radiation behaves as the radio changes could provide new insight into the nature of the emission process."...

Geoff Wright from the University of Sussex adds: "Our observations strongly suggest that a temporary "hotspot" appears close to the pulsar's magnetic pole which switches on and off with the change of state. But why a pulsar should undergo such dramatic and unpredictable changes is completely unknown."

Bat family life

Bats split on family living

An odd report here on how one species of bat has different family arrangements depending on where they live.  That seems unusual.

This part suggests that bat bachelors are unlike human ones:

"But it is also possible that the males choose not to roost with the females. When you look at the nursery colony in Ilkley, mothers and pups often have a lot of ectoparasites like ticks and mites. In a warm, crowded nursery, parasites can thrive, especially if there's less time for good personal hygiene. Parasites not only make life uncomfortable but can affect a bat's health. The males that live by themselves are usually very clean in their bachelor pads, so you can understand why they might not want to move in," he added.

I continue to be amazed at how black flying foxes in the colony I pass every day still hang around in the summer sun instead of going for shadier trees.

When the American Right used to be sensible

7 uncovered quotes that reveal just how crazy the NRA’s become - Salon.com

I like this one in particular:

“There’s no reason why on the street today a citizen should be carrying loaded weapons,” said California Gov. Ronald Reagan in May 1967, after two dozen Black Panther Party members walked into the California Statehouse carrying rifles to protest a gun-control bill. Reagan said guns were “a ridiculous way to solve problems that have to be solved among people of good will.”

 This article notes that Reagan then swung around to be very pro-gun rights in 1975 in "his column"  in Guns and Ammo magazine, but post presidency he swung again:

The Firearm Owners Protection Act of 1986 will be remembered as an important piece of legislation for gun rights. However, Reagan also cast his support behind the two most controversial pieces of gun control legislation of the past 30 years. His support of the Assault Weapons Ban in 1994 may have directly led to the ban winning the approval of Congress. Congress passed the ban by a vote of 216-214. In addition to Klug voting for the ban after Reagan’s last minute plea, Rep. Dick Swett, D-N.H., also credited Reagan’s support of the bill for helping him decide to cast a favorable vote.

Does the NRA blame Alzheimer's Disease for his later support of gun control, I wonder?  I see from this article that he was not formally diagnosed with it until 2004, even though many suspect he started to suffer from it during his second term.  (That linked article makes out a pretty convincing sounding case that he was, actually.) 

A spot of good news

With group effort, Japan suicides fall to 15-year low - CSMonitor.com

Of minor interest:

“As they keep blaming themselves for business failure, saying, ‘I’ve done wrong’ or ‘I’ve caused trouble to society,’ that totally impairs their judgment,” says Hisao Sato who started a suicide prevention program in 2002 in Akita city, some 720 miles north of Tokyo. The region is notorious for being home to the highest suicide rates.

I've been within 80 km or so of Akita quite a few times but never visited it.   I am told there is not much there, but it is such a lonely looking corner of the country I've always felt it would welcome my presence as an international tourist.  It is also close to a Marian apparition, complete with weeping statue.  (Mind you, we briefly had one of those in a Brisbane suburb a few years ago, and I went and had a look.  I think I have mentioned that before.)

A look at Hare Krishna

My years as a Hare Krishna

This is an interesting account of a woman who got into Hare Krishna but who has now moved away from it.  She's still sympathetic to the religion, though.

I note that she was obviously no stranger to recreational drug taking before she got into it.  I have a family member who is (last I heard) still in the religion, who came to it with some recreational drug experience (of a worrying degree, apparently.  I don't know the full details, though.)

I guess this is of no great surprise:  I tend to think anyone who tries anything more psychoactive than, say, marijuana, is showing signs of spiritual aimlessness which a strong communitarian religious practice like Hare Krishna is able to address.  (Gee, I still don't like using the word "spiritual".)  

Anyhow, one of the comments that follow the article is cruel, but funny:

I used to live over the back fence from a Hare Krisna house in Brisbane - 24 hour cycle chanting hare krisna, hare krisna, hare rama, rama rama etc. - so I got to know the words.

My take was it suited wimpy directionless people attracted to traditional conservative roles with an appearance of something special and different

Just when you thought nuclear holocaust had gone away...

Nuclear war accidents: Minutemen missiles in silos should be abolished. - Slate Magazine

Ros Rosenbaum argues that the risk of an accidental nuclear exchange is still high, particularly from the land based Minuteman missiles.   Computers are now a large part of the problem:

The silo-based missiles have been "detargeted," we've been told, but can easily be retargeted in seconds with a burst of code containing—say, Moscow's GPS coordinates. They've been detargeted but not de-alerted (something I called for back 2008 in Slate). They're still ready to go, at a moment's notice, vulnerable to hackers despite the claims by some security experts they're "air gapped from the internet"—but think USB sticks.

Nobody has yet explained the incident in late 2010 when 50 nuclear missiles in Wyoming stopped responding to the C3I system for a frightening period of time. The Pentagon hastened to say, hey, no problem, don’t worry that our computer system isn't capable of error-proof command and control of 50 nuclear missiles for just a little while. The episode was not confidence-inducing, and it reminded us how much world-destroying power is entrusted to glitch-prone computer architecture. The fact that this sensational story was virtually ignored is further evidence of head-in-the sand consciousness we have about nuclear power. 

When I discussed the matter of our "launch posture" with a Pentagon general who specialized in nuclear affairs, he refused to say whether these missiles could still be launched on the basis of "dual phenomenology." This obfuscatory euphemism means that once we receive signals from two electronic tracking systems—radar and satellite—that something on the screens looks like an attack, we'd face the "use it or lose it" choice. We'd have to "launch on warning" before we knew that the warnings were not "false positives" like the flock of geese. Fortunately, it's unlikely there could be two simultaneous false positives in our dual phenomenology, but a statistician's analysis has argued that eventually it would happen. One prominent statistics expert, Martin Hellman, one of the inventors of the "trap door" and "public key" methods of encryption for the Internet, calculated a 1-in-10 chance of a nuclear exchange in the next decade, and Scientific American put it at a not-so-reassuring 1-in-30 for the same period.

Bad news from the Andes

Unprecedented glacier melting in the Andes blamed on climate change

While judging what's going on with glaciers in the Himalayas seems to be quite tricky, it has always seemed that the fate of South American glaciers has been clearer.  And it does have serious implications for water supply:

The Santa River valley in Peru will be most affected, as its hundreds of thousands of inhabitants heavily rely on glacier water for agriculture, domestic consumption, and hydropower. Large cities, such as La Paz in Bolivia, could also face shortages. "Glaciers provide about 15% of the La Paz water supply throughout the year, increasing to about 27% during the dry season," says Alvaro Soruco, a Bolivian researcher who took part in the study.

I should also mention that this is one reason I liked Quantum of Solace:  the writers seemed to be well aware of climate change causing problems in that part of the world, and hence the evil scheme to store desperately needed water underground kinda made sense.

King George Square designer wouldn't change a thing despite calls to bring back the grass  | The Courier-Mail

Obviously, it's not just me then.

I reckon the redesigned King George Square in the heart of Brisbane is a horrendous hot, glare-y and unwelcoming space which people scuttle across as soon as possible to avoid heat stroke, with lines that make it look like there's a bomb shelter beneath it.

Many people seem to agree.

In fact, I have long thought that Brisbane's general appearance took a turn for the worse under Campbell Newman as Lord Mayor.   I never liked his predecessor Jim Soorley at a personal level, but at least he seemed to have a team of urban designers who had decent ideas for the look of the city.  I think Newman  is a typical engineer;  all interested in efficiency and machines, but wouldn't recognize pleasing aesthetic design if it bit him.

More details needed

Spacecraft caused car crash, say pair

Here's a peculiar story from just outside of Brisbane that happened last weekend.  Surely if they were genuine, one of the guys involved is going to turn up on TV to explain more?:

TWO men who walked away from a car crash near Brisbane's Wivenhoe Dam claimed to be chasing an alien spacecraft when found by police.

Police and the driver's insurance company received several sketchy phone calls from the men, who appeared to be convinced paranormal activity caused the crash.

Police received the first call from the men at 2.25am on Friday, saying they had been in an accident at Split Yard Creek and asked for the RAAF to attend...

Police said the conversations with the men were vague and at times barely understandable.

The men began to ''freak out'', telling the insurance company they were about to disappear and referred to the area as the Bermuda Triangle, police said.

Police called the men back, with the second male answering the phone, telling police there were ''some really weird things going on'' and they had abandoned the car.

Police received another call from the men at 4am, claiming that ''something paranormal'' had occurred and ''big bright lights'' caused the car accident.

Police found the men at 4.10am at the intersection of Wivenhoe-Somerset and Hyne roads. They were armed with knives and appeared to be protecting themselves.

The men became aggressive, claiming ''there were more of them around''.
The car's driver was breathalysed. He was over the limit and given a notice to appear in court.

The drink driving offence doesn't necessarily mean much with our .05 limit.  Drunks rarely freak out that way anyway, I reckon.   I have a hunch there might have been more in their system than alcohol, but I would like to be wrong.

Sauerkraut, scurvy and Australia Day

Why sauerkraut is good for you | Life and style | The Guardian

...as long as you choose the unpasteurised sort, sauerkraut is teeming with beneficial lactobacillus bacteria – more than is in live yoghurt – which increase the healthy flora in the intestinal tract.

But where does one get unpasteurised sauerkraut?  Surely the stuff in tins or jars doesn't count?

In fact, the article does point out:

Do not confuse sauerkraut with vinegary, pickled cabbage.

I am not sure now whether I have had proper sauerkraut or not.  The real stuff sounds as if it is easy to make at home:

Sauerkraut is made by lactic fermentation, an age-old technique now in vogue for its health benefits. The necessary bacteria and yeasts are naturally present on cabbage leaves. Apart from salt, which starts the process, no other ingredients are required. So avoid buying brands with added chemical preservatives.

This all reminds me;  I didn't know until the visit to the replica Endeavour in Sydney a couple of years ago that Captain Cook had sauerkraut on board to help ward off scurvy.  According to this detailed BBC history article, it's not clear how successful it was.

Scurvy sure doesn't sound pleasant to see:

Their symptoms were vividly described by Richard Walter, the chaplain who wrote up the official account of the voyage. Here were descriptions of its ghastly traces: skin black as ink, ulcers, difficult respiration, rictus of the limbs, teeth falling out and, perhaps most revolting of all, a strange plethora of gum tissue sprouting out of the mouth, which immediately rotted and lent the victim's breath an abominable odour.

 But there's more:

There were strange sensory and psychological effects too. Scurvy seems to have disarmed the sensory inhibitors that keep taste, smell and hearing under control and stop us from feeling too much. When sufferers got hold of the fruit they had been craving they swallowed it (said Walter) 'with emotions of the most voluptuous luxury'. The sound of a gunshot was enough to kill a man in the last stages of scurvy, while the smell of blossoms from the shore could cause him to cry out in agony. This susceptibility of the senses was accompanied by a disposition to cry at the slightest disappointment, and to yearn hopelessly and passionately for home.

Now we know that scurvy was a cocktail of vitamin deficiencies, mainly of C and B, sometimes compounded by an overdose of A from eating seals' livers. Altogether these produced a breakdown in the cellular structure of the body, evident in the putrescence of the flesh and bones of sufferers, together with night blindness and personality disorders associated with pellagra. In the 18th century no one knew what caused scurvy, whose symptoms were so various it was sometimes mistaken for asthma, leprosy, syphilis, dysentery and madness.

The article points out that, although it had been worked out that citrus juice prevented it, Cook believed it was malt that was keeping his men (relatively) healthy.   In fact, it doesn't mention Cook having citrus on board at all.   I thought he did?

Ah, here we go.  Another article about Cook and scurvy, pointing out that he took "rob":

 
But, the author tells us, there probably was enough useful vitamin C in the Sour Krout (amusingly, that's apparently the spelling at the time) to be an "anti-scorbutic."  Cook used psychology to get the crew to eat it:

It goes on to note that Cook knew that fresh vegetables of most kinds would cure it:

Despite this, some on the voyage did have trouble with the scurvy, including Banks himself:

Well, I think we've all learnt something tonight....

Update:  It's occurred to me that Australians underappreciate the importance of sauerkraut in the maritime exploration of Australia, so I have changed the title.   I suggest making sure some sauerkraut is available at the Australia day bar-b-q this weekend, and if anyone asks why, feel free to quote from this post in your best Robert Hughes imitation voice.

About comedians

Alan Davies interview: 'I'm like a fine wine. I'm maturing' | Media | The Guardian

Alan Davies makes an interesting comment in this interview:

During his career he has seen plenty of clowns who could also benefit from time on an analyst's couch: "There are two types of comedians, self-harmers and golfers. The second lot are out on the golf course, they love being famous, playing golf, having their Rolls-Royce and house in Barbados, with no guilt. For others there is a sense that you had to pay your dues – 'my life is shit'. Why not just play golf and enjoy it?"

I see he is aged 46.  I'm not sure if he seems that age or not.

The Right in the US has gone nuts - Part Whatever

Noonan: His Terms Are Always Hostile Ones - WSJ.com

Peggy Noonan, who I don't read all that often, but who has seemed at times to represent moderate Republicanism reasonably well,  has well and truly decided she's on side with the nutty Tea Party wing of the Republicans after all:

President Obama has been using the days and weeks leading up to his inauguration to show the depth of his disdain for the leaders of the other major party and, by inference, that party's voters, which is to say more or less half the country. He has been spending his time alienating instead of summoning. It has left the political air more sour and estranged. 

As a presidential style this is something strange and new. That has to be said again: It is new, and does not augur well. 

 What was remarkable about the president's news conference Monday is that he didn't seem to think he had to mask his partisan rancor or be large-spirited. He bristled with unashamed hostility for Republicans on the Hill.  They are holding the economy "ransom," they are using the threat of "crashing the American economy" as "leverage," some are "absolutist" while others are "consumed with partisan brinkmanship." They are holding "a gun at the head of the American people." And what is "motivating and propelling" them is not a desire for debt reduction, as they claim. They are "suspicious about government's commitment . . . to make sure that seniors have decent health care as they get older. They have suspicions about Social Security. They have suspicions about whether government should make sure that kids in poverty are getting enough to eat, or whether we should be spending money on medical research." 

And yet, "when I'm over here at the congressional picnic and folks are coming up and taking pictures with their family, I promise you, Michelle and I are very nice to them."

You're nice to them? To people who'd take food from the mouths of babes? 

Then, grimly: "But it doesn't prevent them from going onto the floor of the House and blasting me for being a big-spending socialist." Conservative media outlets "demonize" the president, he complained, and so Republican legislators fear standing near him.

If Richard Nixon talked like that, they'd have called him paranoid and self-pitying. Oh wait . . .

 I'm happy to allow that Obama is not, and never was, the Messiah.  He may have a big streak of vanity for all I know.

But  Noonan's shock and outrage that Obama is telling Republicans that he doesn't think they are acting in good faith and criticising their 4 years of over-the-topic hyperbole and crank theories - that is ridiculous in the extreme.   Republicans have been absurd in the way they have argued under Obama - everything is "socialism", "death panels" (you don't need links for those, surely), "treason", deserving impeachment; even when the ideas under discussion are ones that Republicans at the State level have implemented and only now being expanded to the Federal level (Romney and health care; the contraceptive mandate in many States, Republicans in the New York Senate on gun control.)  The hypocrisy and hyperbole of the Republicans over the last 4 years has been breathtaking.

And as for the President's recommendations on gun control - Noonan thinks they are OK, but still has to struggle to find a way to criticise him:

His gun-control recommendations themselves seemed, on balance, reasonable and moderate. I don't remember that the Second Amendment died when Bill Clinton banned assault rifles; it seemed to thrive, and good, too. That ban shouldn't have been allowed to expire in 2004.

What was offensive about the president's recommendations is what they excluded. He had nothing to say about America's culture of violence—its movies, TV shows and videogames. Excuse me, there will be a study of videogames; they are going to do "research" on whether seeing 10,000 heads explode on video screens every day might lead unstable young men to think about making heads explode. You'll need a real genius to figure that out.

The president at one point asked congressmen in traditionally gun-supporting districts to take a chance, do the right thing and support some limits. But when it comes to challenging Hollywood—where he traditionally gets support, and from which he has taken great amounts of money for past campaigns and no doubt will for future libraries—he doesn't seem to think he has to do the right thing. He doesn't even have to talk about it. It wouldn't be good to have Steven Spielberg or Quentin Tarantino running around shouting "First Amendment, slippery slope!" or have various powerful and admired actors worrying their brows, to the extent their brows can be worried.

What, pray tell, does Noonan think a President can do, exactly, about cinema violence?  (And putting Steven Spielberg in there as if his movies have been groundbreaking in the gratuitous gun violence stakes is ridiculous.   The trend was really started by Right wing Hollywood figures, if you ask me.)

Noonan's commentary has therefore officially become nuts.  The list of moderate Right wing commentary worth reading has become vanishingly small.

A mild dose

I mentioned a couple of posts back that I was having an interesting viral infection.   It's shingles - the illness you can get years after you've had chickenpox, when the varicella-zoster virus comes out of its hiding place on your nerves and gives you a skin rash with possible complications.

I don't like the way certain viruses do that "never leave your system" trick.  Like most in my family, I'm unlucky enough to get cold sores too, so now I've got two herpes related viruses always hanging around waiting to re-emerge if feeling run down.  (In fact, now that I think of it, how come people like me don't always get a break out of cold sores at the same time that they get shingles - both are thought to be related to the immune system dipping a bit.)

My chickenpox experience was as an adult and was of average unpleasantness, I guess.  My Mum had an attack of shingles in her 50's and it bothered her quite a bit for a couple of months; I remember David Letterman had one a decade or more ago which kept him off TV for a while.  So I was generally aware of the illness.  (One website says about 1 in 5 adults in Australia will have an attack.)

On Monday last week I noticed an itch on my back.  It felt a bit unusual, and looking in the mirror it seemed to be in a smallish oval red patch just off the spine, but I thought the redness may have just have been from scratching.  It was still looking like a rash on Tuesday evening though, and after checking some photos on the internet of what a shingles rash could look like, I headed off the GP.

He seemed to very much doubt it was shingles, as it was only moderately itchy, and didn't have any pain or much in the way of "pins and needles" feeling.   Anyway, he took a swab and gave me a week long course of anti-viral tablets just to be safe.

Over the next day or two, I asked everyone at work about whether they had shingles, and whether they had much pain with it.  As with the doctor, everyone I spoke to had the attitude "I think you'd really know about it if it was shingles - it's pretty painful."  Yet I was continuing with just mild itchiness.

The GP rang a couple of nights later and said the test was positive for the virus - it was shingles; just a very mild case apparently.  So I'll continue my anti-virals for a couple more days and just hope that is as bad as it gets.   (The rash is now less distinct and less itchy, but still there.)

I've had a look around at stuff on the internet about shingles.  I see that there is a vaccine they can give now for those aged over 60, when the complications can be worse.   But the most interesting thing I read was this - about how it is not clear whether widespread childhood immunisation against chickenpox may actually lead to more cases of adult shingles.  (I'll add a couple of the earlier paragraphs which set the scene before the most interesting bit):

 The varicella-zoster virus (VZV) is so named because it causes two distinct illnesses: varicella (chickenpox), following primary infection, and herpes zoster (shingles), following reactivation of latent virus....

  Herpes zoster or shingles is a sporadic disease, caused by reactivation of latent VZV in sensory nerve ganglia. It is usually self-limiting and is characterised by severe pain with dermatomal distribution, sometimes followed by post-herpetic neuralgia which can be chronic and debilitating in the elderly.^10,11 Although herpes zoster can occur at any age, most cases occur after the age of 50 with the incidence of complications also increasing with age.¹² However, children infected in utero or those who acquire varicella before the age of 1 year, and patients on immunosuppressive drugs or infected with human immunodeficiency virus, are also at increased risk of herpes zoster.^13–15 A new herpes zoster vaccine which is over 60% effective in reducing the burden of herpes zoster and post-herpetic neuralgia¹⁶ has been available on the private market in Australia since 2008. The zoster vaccine is formulated from the same VZV strain (Oka-derived) as the licensed varicella (chickenpox) vaccines but is of higher potency (at least 14 times greater).

  In 1952, Hope-Simpson proposed the hypothesis that exposure to varicella may boost immunity against herpes zoster.²⁰ There is increasing evidence to support that hypothesis, with two observational studies showing lower rates of herpes zoster in groups who have been exposed to varicella.^21,22 If exposure to wild varicella provides boosting and protection against activation of herpes zoster, universal infant varicella vaccination and the subsequent decline in wild varicella may result in an increase in herpes zoster incidence among those previously infected.²³ Mathematical modelling has also suggested that widespread infant varicella vaccination might result in a significant increase in the incidence of herpes zoster, possibly over a 40-year period.²³ An Australian study, performed to assess the potential impact of universal varicella vaccination based on this hypothesis, suggested that total morbidity due to varicella and herpes zoster in Australia would decrease for the first 7 years of a population program, but, for 8–51 years after vaccination commenced, total morbidity was predicted to be higher than pre-vaccination levels.²⁴ However, this model assumed 90% vaccination coverage and 93% vaccine effectiveness. These predictions might not be correct, particularly given that overall vaccine coverage and effectiveness are now estimated to be less than that originally used in the model. Currently, surveillance data from the USA, where varicella immunisation has been recommended for over a decade, indicates a large reduction in varicella morbidity with no increase in zoster disease yet demonstrated.²⁵

Chickenpox and shingles are therefore a little complicated.  If they go the way of smallpox, good for us.

Deep under [the] cover[s]

A load of Thunderballs: James Bond is fiction, not a police instruction manual | Jonathan Freedland | Comment is free | The Guardian

Well, I haven't paid much attention to this before:  there's a case running in the UK in which a group of women (and one man) are suing the police service for allowing undercover operatives to engage in sexual relationships with them.   As the opinion piece above notes, a judge has referred to what James Bond would be allowed to get up, much to the annoyance of some observers.

This line of work is (or should be, if you were raised right) an ethical minefield for those engaging in it.  At least, you might think, the relationships are over and done with in a relatively short time.

But that is what's really surprising:  some of these relationships gone on for a very long time -

Some may question how much the women involved really suffered: they were with a man long ago who was not what he claimed to be – OK, not nice, but move on. Such an attitude was hinted at in the remarks by a male activist who slept with an undercover policewoman in a tent at a "climate camp" and who told the Guardian he did not want to sue the police because the one-night stand was "nothing meaningful".

But for the others these were not one-night stands, they were relationships of long standing – six years in one case, five in another – that were enormously meaningful. Those involved tell of deep and genuine attachments, the men integrated into their lives as partners, living together, travelling together, attending family gatherings, sitting at a parent's bedside, even attending a funeral.

There are at least four children from these relationships, some of whom have only now, decades later, discovered who their father really was – and that they were born of a great act of deception.

The greatest pain seems to have come afterwards. Uncannily, most of the relationships all seem to have ended the same way: a sudden departure, a postcard from abroad, and then silence. Some women spent months or even years trying to work out what had gone wrong, travelling far in search of answers. Others found that their ability to trust had been shattered. If the man they had loved turned out to be an agent of the state, what else should they be suspicious of? Could they trust their colleagues, their friends? And the question that nags above all others: was it all a fake, did he not love me at all? One woman tells friends simply: "Five years of my life was built on a lie."

There was rightly an outcry about the News of the World's hacking of people's voicemail messages. But this was the hacking of people's lives, burrowing into the most intimate spaces of the heart in order to do a job, all authorised by the police. It is state-sanctioned emotional abuse.

Remarkable.

In defence of thimerosal

Mercury treaty debate: Should thimerosal be banned as a vaccine preservative? - Slate Magazine

A detailed and interesting explanation here as to why the mercury compound thimersol should be allowed to remain in vaccines.

Other forms of problematic mercury are not so harmless, however:

Estimating its global impact is difficult, but in some populations almost 2 percent of children are born with mental retardation caused by mercury poisoning.

This all reminds me:  the 1980 science fiction novel Timescape by Gregory Benford, which I only partially read since I don't care for Benford's inability to write likeable characters, starts with a near future "mercury hunt" in the sewers under some university town.  If I recall correctly, it was an extrapolation that mercury for scientific use was becoming in shorter supply and much more expensive, and hence these scavenging trips through drains and sewers would be viable in the future.  If I am remembering it right, that was one (amongst many) predictions in the book that failed to pass.   [If you want to guarantee a science fiction book with a short shelf life, set it about the near future and make lots of detailed predictions about what will go wrong.]

As it happens, I was thinking about the silliness of the midichlorians while in the shower last night:  turning an appealing mystical/spiritual force in the first films into something sounding like a virus infection.

And speaking of virus infections - I'm having an interesting one at the moment.  Worth a separate post...

 

Australia heat wave in detail

What's causing Australia's heat wave?

I haven't commented on all the publicity about the nation wide heatwave of a couple of weeks ago, as I was waiting on a bit more explanation of how they work it out from the Bureau of Meteorology.

Well, the article above does give more detail, and is well worth reading.

No matter how much the reality disconnected Right wing of politics complains, it looks clear that it was a very unusual event.  

Update:  how appropriate that I posted this on the morning that Sydney has (unexpectedly)  had its hottest day on record by .5 degree.  (45.8 - which is by any standard remarkably hot.)

Hobart broke its record by a full 1 degree on 4 January.

A normally temperate place like that breaking its record by a full degree is very remarkable, I reckon.

Inflatable space homes on the way

Space station to get $18 million balloon-like room (Update)

NASA is partnering with a commercial space company in a bid to replace the cumbersome "metal cans" that now serve as astronauts' homes in space with inflatable bounce-house-like habitats that can be deployed on the cheap.

A $17.8 million test project will send to the International Space Station an inflatable room that can be compressed into a 7-foot (2.1-meter) tube for delivery, officials said Wednesday in a news conference at North Las Vegas-based Bigelow Aerospace.

 If the module proves durable during two years at the space station, it could open the door to habitats on the moon and missions to Mars, NASA engineer Glen Miller said.

These will be rather useless as shelters from space radiation, though.

The odourless underarm gene

Deodorants: Do we really need them?

Well, I had always wondered why some people (like my father, actually) do not produce body odour no matter how sweaty a day they may have had.  I always assumed it was a quirk of the bacterial flora on the skin, but it appears that for some it is in the genes:

New research shows that more than 75 per cent of people with a particular version of a gene don't produce under-arm odour but use deodorant anyway. The study was based on a sample of 6,495 women who are part of the wider Children of the 90s study at the University of Bristol. The researchers found that about two per cent (117 out of 6,495) of mothers carry a rare version of a particular gene (ABCC11), which means they don't produce any under-arm odour....

Speaking about the novel finding, published today in the Journal of Investigative Dermatology, the lead author Professor Ian Day said: 'An important finding of this study relates to those individuals who, according to their genotype, do not produce under-arm odour. One quarter of these individuals must consciously or subconsciously recognise that they do not produce odour and do not use deodorant, whereas most odour producers do use deodorant. However, three quarters of those who do not produce an odour regularly use deodorants; we believe that these people simply follow socio-cultural norms.  This contrasts with the situation in North East Asia, where most people do not need to use deodorant and they don't.' ...

The authors highlight that people who carry this rare genetic variant are also more likely to have dry (rather than sticky) ear wax and that checking ear wax is a good indicator of whether or not a person produces under-arm odour.

Previous studies have shown that there is a link between a genetic variant located in the ABCC11 gene and under-arm odour. Sweat glands produce sweat which, combined with bacteria, result in under-arm odour. The production of odour depends on the existence of an active ABCC11 gene. However, the ABCC11 gene is known to be inactive in some people.

Miller talks, a lot

Bryan Appleyard :  Jonathan Miller: Talking About Termites

Here's a cheery article by Bryan Appleyard about a recent interview with Jonathan Miller.   

Paranoia and the Republicans

From a column in the LA Times, a very accurate take on the nuttiness infecting large slabs of the Right in the US at the moment:

Although assault weapons have been banned in the past without a loss of liberty, and no regulation Obama is considering comes close to negating the right to keep and bear arms, one congressman from Texas said he would push impeachment of the president for trying to nullify the 2nd Amendment.

Tea party hero Sen. Rand Paul of Kentucky equated Obama’s proposed administrative actions with the monarchy of King George III and pledged to fight the president “tooth and nail” as if 2013 were 1776.

Clearly, the debate about guns is not going to be a reasoned discussion about how to better regulate the hundreds of millions of guns in America and keep them out of the hands of criminals and crazy people. At least on the right, it will be an exercise in paranoia and fear-mongering.

Meanwhile, in the sane state of New York, Republican and Democratic legislators have joined together to pass new gun restrictions that will ban high-capacity magazines, strictly limit ownership of assault weapons and ban their sale online. They did it quickly in a bipartisan fashion and Gov. Andrew Cuomo signed the measure into law on Tuesday. So far, the Empire State shows no sign of turning into a Stalinist nightmare. Other than the significant exceptions of Illinois and Michigan, gun deaths are generally lower in states, such as California, that have strict guns laws. New York was on that list even before this newest law was passed.

Of the annual 30,000 gun deaths in the U.S., only 200 are homicides resulting from acts of self-defense, according to the FBI. Still, no one is talking about stripping away the right of anyone to own a gun to scare off a prowler or hold off a rapist (even though most people shot by guns in homes are relatives and friends). The only types of gun anyone is talking about restricting are the assault rifles that former Gens. Colin Powell and Stanley McChrystal say should only be in the hands of soldiers -- the kind of weapon used by a mentally unstable young man to murder first-graders in Newtown.

 But folks on the right disagree with the generals. Apparently, that is the kind of weapon they think they may desperately need in the event of civil war against the would-be monarch in the White House.

Legal issues

Virgin threatens to pull out of projected spaceport | Science | guardian.co.uk

I've said before that this complicated and expensive form of short joyride may well have a very short life if there is any accident.  It's not like air travel, where people are always going to need and want the product.

This article talks about some of the liability limitation that is involved in the project.  I guess that, given it is only rich people with plenty of money to sue who can afford it,  such limits are absolutely essential.

I still think that high altitude balloon rides into space, (perhaps using cheaper hydrogen?), may well be a better product.

Yet another exotic disease I barely knew

Step closer to parasite vaccine (Science Alert)

 Scientists - including a geneticist at The University of Western Australia - are a step closer to developing a vaccine against a fatally infectious parasite carried in the bite of sandflies.

Visceral leishmaniasis, also known as black fever, is the second-largest parasitic killer in the world after malaria.  The parasite migrates to organs such as liver, spleen and bone marrow and if left untreated will almost always be fatal. Symptoms include fever, weight loss, mucosal ulcers, fatigue, anemia and substantial swelling of the liver and spleen.

Leishmaniasis affects 12 million people and there are an estimated 1.5 million new cases annually mainly in India, Bangladesh, Nepal, Sudan, South Sudan, Ethiopia and Brazil.

I'll add it to the list of "exotic diseases I feel I should have known about, but didn't."

Stem cell competition

Court lifts cloud over embryonic stem cells : Nature News

Here's an interesting report noting that stem cells sourced by reprogramming adult cells are well on their way to replacing embyronic stem cells in terms of total research volume.

This is a good thing.

To test or not to test

Change in PSA levels over time can help predict aggressive prostate cancer

I think I read years ago that earlier testing - in the mid 40's - was perhaps more useful than a first test in one's 50's, perhaps for the same reason.

I never got around to it then, though, but last night I got the form for some blood tests and PSA is included.  The doctor basically said "well, it's the only way we've got of detecting anything", which is true, I guess.   He agreed though that it may well result in unnecessary further investigation or treatment.
 My impression is Australian doctors are more reluctant to give up testing PSA routinely than are some American doctors.  But I could be wrong.

Bond noted

So, I finally saw Skyfall yesterday.

My impressions:    It is, without doubt, the best directed and most visually impressive Bond film ever made.   In particular, I thought it remarkable how seamlessly visual effects are incorporated into the film.   Unlike the Bonds of old, there is really no point (which I can recall) at which you can think "oh, now its cut to the actor  in front of a blue screen," yet there are incredible scenes of destruction and mayhem which just must be visual effects.   (That's the upmarket term now for "special effects" isn't it?)  It just all looks real and terrific.  There is also a well acted loony villain for a change, and in fact the whole Daniel Craig era of "actors who take it seriously" continues.

A few quibbles though - I thought Quantum of Solace was going to be the end of Bond having mid life "do I really want to be doing this job" style crises, but the first third of this film is back to that thematically.  The competitive drinking scene was too much like the one in Raiders of the Lost Ark, although the addition of the scorpion was a nice touch.  (If Spielberg were directing, one would say it was definitely self referential.)   And really, as for the readiness to leap into bed with the most available woman: it is, I think, pretty much recognised now as being dated sexual politics, but the producers still presumably consider it an essential element.  It seems that the way they deal with it in this film is to make these scenes as short as possible - so much so that one of them happens so quickly it makes him look (at first) more like a break in rapist than a welcome lover.  Would they really lose anything by not showing him bed a woman in the next film?  I doubt it.

But, overall, I would have to say the film remains quite satisfying.   I particularly like Ralph taking over a key role:  I have long admired him as an actor in virtually whatever he does.

Update:  the biggest quibble perhaps should be - where is the extra bullet hole from the opening scene?    That's never explained.  I see that the issue has been given some detailed internet analysis. 

Galaxy mystery

I should have noted this story from last week:

"When we looked at the dwarf galaxies surrounding Andromeda, we expected to find them buzzing around randomly, like angry bees around a hive. "Instead, we've found that half of Andromeda's satellites are orbiting together in an immense plane, which is more than a million light years in diameter but only 30 000 light years thick. These dwarf galaxies have formed a ring around Andromeda."

 "This was completely unexpected – the chance of this happening randomly is next to nothing. It really is just weird," said Professor Lewis.

 Large galaxies, like Andromeda and our own Milky Way, have long been known to be orbited by an entourage of smaller galaxies. These small galaxies, which are individually anywhere from ten to at least hundreds of thousands of times fainter than their bright hosts, were thought to trace a path around the big galaxy that was independent of every other dwarf galaxy.

 For several decades, astronomers have used computer models to predict how dwarf galaxies should orbit large galaxies, and every time they found that dwarfs should be scattered randomly over the sky. Never, in these synthetic universes, did they see dwarfs arranged in a plane like that observed around Andromeda.

It's odd how much mystery is still involved in understanding the motion of galaxies, both individually and collectively.

Hitting the wall

How do you know if you ran through a wall? Testing the nature of dark energy and dark matter

Researchers from Canada, California, and Poland have devised a straightforward way to test an intriguing idea about the nature of dark energy and dark matter. A global array of atomic magnetometers – small laboratory devices that can sense minute changes in magnetic fields – could signal when Earth passes through fractures in space known as domain walls. These structures could be the answer to the universe's darkest mysteries.

Can't say I've ever heard of "domain walls" before.  Interesting.

Three below the belt

A few articles all with a "below the belt" theme - sort of:

*  the first is a bit of a cheat:  Mary Beard has an interesting review of a new book about shopping in ancient Rome, but because part of the material relates to a poet who was making a bit of a joke, she gives it the title "Banter About Dildoes".   It's a very interesting read anyway.

*  Slate had an article a week ago about the history of condoms in the US.  Again all very interesting.  [As an aside, the availability of condoms in Australia is significant for family reasons.  My maternal grandparents were divorced - or maybe permanently separated, I forget which - by the time I was born.  My mother told me that the relationship had gone bad when, on one of his return visits to their country  home  after working down in Brisbane in World War 2, my grandmother was furious to find he had a condom in his pocket.  She took as a sure sign he was up to no good while away.  I wonder if it was a US condom?]

*  Slate also has a fascinating article about the importance to reproductive health of the microbacterial mix in a vagina:

A healthy vaginal microbiome produces lactic acid and hydrogen peroxide, which maintain a level of acidity that keeps troublemaking microbes at bay. When the vaginal community becomes unbalanced, on the other hand, acidity decreases. The wrong microbes may then invade or, if they’re already present, bloom.

This disturbance can cause bacterial vaginosis—not really an infection, but an out-of-whack ecosystem. It sounds like a trifling problem, and half of women with vaginosis may display no obvious symptoms. But this minor-seeming imbalance can have major consequences.

Vaginosis increases the risk of contracting secondary infections, from herpes to HIV. But even on its own, the microbial shift may prompt low-grade inflammation that can derail reproduction. It can prevent fertilization in would-be mothers, prompt spontaneous abortion in pregnant women, and increase the risk of preterm birth later in pregnancy.

If the vaginal microbiome were suddenly to shift across the entire human population, it's not unreasonable to predict that humanity would go extinct.

 Amongst other fascinating details, there is also the question of how far bacteria get into the female reproductive system:

In 2011, a group at Harvard found that 40 percent of placentas from more than 500 preterm children born by C-section contained culturable microbes. In this case, those placentas colonized by vaginosis-associated species were slightly inflamed. But the placentas coated with lactobacilli were not.

Australian fertility specialists have observed that fluid extracted from ovaries wasn’t sterile, either; it also contained bacteria. The study group consisted of women seeking help with conception. Women who harbored lactobacilli, the researchers found, more often had successful outcomes than those who carried other species.  

The microbes may have been introduced during the egg retrieval process, the scientists acknowledged. But they also asked, “Do we really believe that the female upper genital tract is sterile?”

“I think that there's organisms up there all the time, in healthy people,” Reid says. Some of these microbes likely ascend from the vagina.

And, in the last section, the peculiar American obsession with douching comes in for criticism:

When I asked Cottrell about douching, she told me a story. About a decade ago, flummoxed by the high infant mortality rates in some African-American communities in the Florida panhandle—which were more than twice the rate for Caucasian infants—she began looking for explanations.

“I kept seeing bacterial vaginosis present in mothers whose babies died,” she recalls. “That’s when I started reading about vaginosis.”

She happened on statistics suggesting that one in three American women douche and that some African-American cohorts douched nearly twice as often. Showing that douching directly causes infant mortality remains difficult, yet her resulting paper, published in 2010, reads like an anti-douching manifesto.

Douching has been linked to preterm birth, an elevated risk of acquiring HIV, ectopic pregnancies, cervical cancer, and endometriosis, she points out. It may perpetuate the very condition it’s often intended to address: vaginosis. Scientists at Johns Hopkins have found that, after stopping the practice, bacterial imbalances resolved on their own.

“We recommend not doing it, that's the bottom line,” says Cottrell.

 *   is there any other country that has these products advertised on TV?  Do they still advertise them - I haven't been there for some years - but look at this creepy 1980's ad .  I see that they are certainly still used:

An estimated 20% to 40% of American women between ages 15 and 44 say they use a vaginal douche. Higher rates are seen in teens and African-American and Hispanic women. Besides making themselves feel fresher, women say they douche to get rid of unpleasant odors, wash away menstrual blood after their period, avoid getting sexually transmitted diseases, and prevent a pregnancyafter intercourse. 

 I find this very odd.

Let India do your head in

Last week, SBS showed the first episode of a 3 part documentary "Welcome to India" and it made for fascinating, if rather disturbing viewing.

I've heard people who have been there say that the country is confronting and confounding to Western eyes; the mix of beauty, poverty, striving, and resignation to fate is apparently very hard to process, and I think this documentary illustrates this extremely well.

(These themes were also evident in last years' 2 part doco by Kevin McCloud "Slumming It", which I think I recommended at the time.)

Welcome to India basically tries to spin an optimistic take on how people in India seek to improve their lot by hard, but often disgusting and dangerous, work.   On the one hand, you can admire this, as well as the mutual support that some families, even work families, display.  On the other, the show seems to acknowledge but never wants to dwell on the exploitation that is clear in much of what goes on in the country.  Yeah, the guy who supervises the workers who sluice mud from the jewellery district's drains for the tiny amount of gold dust they may recover pays them every week (after, it seems, spending much of his day by napping in the middle of the workplace,) but he's ruthless in what he'll pay the guy who gets into the rat infested drains to dig out the mud overnight, and he just shrugs his shoulders about how dangerous it is for the other workers who smelt down a mercury mixture to get out the gold.  But "everyone loves gold" he beams at one point.   (Well, that makes it all worthwhile, then.)  And those people who live on a beach growing fenugreek have made themselves a nice enough business, and live in a beach slum which is better than many in India, but they resent the late comers to the beach and don't care if the government moves those ones on.

Anyway, I see that the first episode can still be viewed on SBS on Demand, but is also up on Youtube permanently.   Part 2 is on tonight at 9.30 as well.   Well worth your time.

Fickle fate

A lot of people are worried about bushfire danger in New South Wales today, with Sydney expecting 43 degrees and high winds. 

Of the recent bushfire experience in Tasmania, I thought the following photo of Dunalley was remarkable:

I mean, this just doesn't match my mental image of a town likely to burn down due to bushfire:  it looks just like a bit of seaside suburbia with an unremarkable number of trees in backyards or nearby.  And, of course, there is plenty of water nearby.   (Fighting large scale fires with sea water probably doesn't do a lot for any surviving garden, I guess.)

Anyway, good luck New South Wales.

An early opinion for 2013

"Gangster Squad" is an amazingly bland and boring name for a movie, isn't it?  (I've seen billboards around town for it, and have this thought every time I see them.)

Holidays past and past

Happy New Year, Readers.

Christmas was pretty pleasant at the Opinion Dominion household, seeing relatives and friends that we haven't for some time; and on Boxing Day, heading up for a too short stay at Noosaville - that beautiful "just around the corner from Noosa" part of the world that we used to holiday in, but had given a miss for a number of years, especially the last two summers that had the horrendous weather.

It's easier from where we live to visit the Gold Coast, but (apart from that coast's rainforest hinterland areas, which are beautiful but not part of a normal beach holiday) I still say that the Sunshine Coast (the Noosa end of it in particular) runs rings around the area from Southport to the border for physical beauty. Of course, the fact that as a kid my family used to take summer holidays on the beach at Maroochydore, where camping seemed to stretch for miles on either side of the lifesaver clubhouse may influence my feelings as well.  Here's how happy being at the beach used to make me:

(I feel pretty much the same about a good beach holiday 50 years later.)

But seriously, have a look at how nice the water is in these couple of photos, the first of the river at Noosaville just 30 m or so from where we stayed.   (If you don't care for my efforts at producing a moving panorama effect, just click on it and see the whole stitched thing*):

(I'll slip back into nostalgia for a moment and share a photo of me at - I think - Cotton Tree near the mouth of the Maroochy River some years ago:

and as an aside,  note how annoying it is that, even without eating more than before, my almost-post-middle-age torso is wanting to revert to that shape.)

Back to Noosa Heads 2012, where we still managed to find a car park in the bushy part at the end of Hastings Street provided we got there by about 8 am or after about 3.30pm:

Yes sure, driving into Noosa's Hastings Street is a nightmare in the middle of the day at peak holiday season, but you normally want to avoid the sun at that time of day anyway.  

I was extremely happy that the weather was good for the whole week this year:  just one threatened afternoon storm that curtailed things a bit but that was it.   South Easterly winds picked up on the last couple of days, but Noosa Heads is well sheltered from them and the surf was always gentle but intermittently large enough to be fun for people on body boards.  The water seemed particularly glassy and clear and warm this year.  (I have long maintained that you only have to go 20 km south of the Queensland border to find that the ocean water feels noticeably colder, even at the height of summer.  On the other hand, even if you brave the potential killer jelly fish of tropical north Queensland waters in summer, they are like having a tepid bath and not very refreshing at all.  Water at the Sunshine Coast is just right.)

Noosaville still has a great bunch of cafes and bars on the riverfront, although (sad to say) I don't recommend having a meal in the "French bistro" there.  The owners do seem French and bake a nice croissant and assorted pastries for breakfast, but their evening meals are distinctly ordinary.  [On the other hand, if you are visiting Southbank in Brisbane, I do strongly recommend French Martini on Grey Street, which we ate at before Christmas.  Servings sizes are not huge, but the food was very pleasing.]   Back at Noosaville, for simple takeaway, the Red Emperor fish and chip shop opposite Pelican Beach on the river continues to do excellent work feeding hundreds of people a night; Elvis's takeaway next door does decent standard burgers; many of the local pizzas are good and most of the more upmarket places also do takeaway if you don't care to eat in.  It is a good place to eat.

We also hired a boat for a morning of fishing, and my son was happy to catch his first edible sized fish, a whiting.   I didn't realise before that there is a stretch of the river behind a canal developed part which has a a large stretch of foreshore left bushy:  if you nose your boat towards that side and don't look behind you, you can imagine for a minute that you are in a very undeveloped river:

As for the whiting itself, it was kept in a large bucket of water while we tried to see if we could catch another fish to make a shareable meal; we didn't and it was decided that I would take a photo of son holding it before releasing it into the water.  While holding it, it make a clear squeak sort of sound - perhaps regular anglers know that whiting can squeak, but it surprised us and confirmed that it should be released, in case it had just promised us 3 wishes, or something.

I must have forgotten to ask for a million dollars in the end of year Gold Lotto, or maybe it was released under false pretenses.

Anyway, all in all, a very good time was had, both in 1962/3 and 2012.

*  Readers who are interested in stitching photos together for a panorama, and who (like me) have misplaced software for that which came with an older camera, might be interested to note that I found Microsoft's free ICE program did the job very well.   I also actually have deleted my kids from 2 of these photos using the clone tool in PhotoImpact, which has always seemed to me to be a good cheap alternative to Photoshop.

Christmas elsewhere

NRA Fail

NRA press conference: The lesson of Newtown—when gun nuts write gun laws, nuts have guns. - Slate Magazine
This is just one of the many savage media attacks on the NRA approach that "more guns, more guns" is the only response it will consider to mass shootings. 

Funny how it won't acknowledge that it was legally acquired guns that caused the latest horror.   Or that it is not even clear that any increased regime of reportable mental illnesses would have helped.  (For an organisation so keen on civil liberties, I would like to see how many mental or personality issues it thinks should be notifiable to a government register, and how close to access to guns such a person has to be to be included.)

The fact that the Columbine shooting happened in a school that regularly had an armed, uniformed deputy from the local sherriff's office eating lunch in the caferteria was probably something they weren't keen to take questions on either.

It may be early days yet, but there seems to be a sense that the latest killing has turned the tide of opinion against the likes of the NRA.  I  have to say, though, that I agree that the issue of violent games (and movies) is not getting enough attention.  It's just that the NRA is the last organisation that can credibly bring that up...

Abbott considered

What does it profit a man? Between Tony's faith and Abbott's ambition – Opinion – ABC Religion & Ethics (Australian Broadcasting Corporation)

This essay by fellow Catholic Chris Uhlmann about Tony Abbott is very good, I think.

It certainly raises the question of how much conflict Abbott may privately feel about what he does in his current role in politics.

I just still think he is a man who has been appointed above his level of competency and comfort, and I do not imagine him being a good PM.

PS:  Uhlmann does made a crack about Greens being modern pantheists - which has an element of truth to it, I suppose - but it also indicates to me that he can't get over his previously stated belief that climate change is not really science but a religious belief.   He may be OK on the humanities and religion; I don't think he's smart when it comes to science.

Gun control discussed

Well, I certainly hope it is annoying gun lovers of Australia that Slate is running an article noting how John Howard's gun buyback actually did put a sudden end to mass shootings of the kind all so frequent in the US.

While no one realistically suggests such a buy back is politically possible in the US, and the general tone is of pessimism as to what can really be achieved in a country already brimming with private weaponry, Slate does have an interesting article arguing that history tells us the certain forms of violence have been successfully tackled in the US.  I wasn't aware of the incidents mentioned in this aspect of US history:

 One example is class violence, once seen a shameful but ineradicable feature of American life. Beginning in the 1870s, the United States became infamous around the world for the brutality of its labor clashes, in which gun battles, dynamitings, and hand-to-hand combat produced what seemed to be an unending stream of senseless death. Sometimes the violence came at the hands of police: 100 strikers killed during the rail uprising of 1877, 11 children burned to death in the 1914 Ludlow Massacre. On other occasions, it came as retaliation from below. In 1910, men employed by the Bridge and Structural Iron Workers blew up the headquarters of the anti-union Los Angeles Times, killing 21 printers and laborers working inside.

Elsewhere in Slate, a comment in National Review Online that the Bushmaster semi-automatic is not worth worrying about banning because it is (apparently) not powerful enough to reliably kill a deer is given a thorough ridiculing, including showing this ad that illustrates the mentality behind some gun ownership in the States:

 

If I had enough time, I'd adjust the slogan to "Consider your penis inadequate".

But one thing about Slate bothers me:  amongst all this talk of gun control and violence, they are still running prominently an episode by episode commentary on the series Dexter - a show about a psychopath made for entertainment value that has nonetheless (as I detailed a couple of months back) been clearly implicated as having inspired several murders by nutters internationally.

I haven't noticed anyone in the comments section following the Dexter article comment on this weird juxtaposition, where the same liberal leaning publication is both deeply concerned about violence in culture, and celebrating it as entertainment on the same page.

Meanwhile, over in the Atlantic, James Fallows puts succinctly the case against the "more guns is the answer" argument:

To spell it out:

• Being in a shopping mall, on a train, in a theater, or at a school where someone starts shooting is statistically more frequent in America than anywhere else, but is vanishingly unlikely for any individual. Yet if we were to rely on the "more guns make us safer" principle, logically we'd have to carry guns all the time, everywhere, because ... you never know. Jeff Goldberg and I have both railed against TSA policies based on the premise that every single passenger is a potential terrorist. A more-guns policy would involve a similar distortion in everyone's behavior based on outlier threats.
• There is very little real-world evidence of "good guys," or ordinary citizens who happen to be armed, taking out shooters in the way the more-guns hypothesis suggests. After all, and gruesomely, the mother of the murderer in Newtown was heavily armed and well experienced with weapons, and that did not help her or anyone else.
• It is all too easy to imagine the real-world mistakes, chaos, fog-of-war, prejudices, panic, and confusion that would lead a more widely armed citizenry to compound rather than the limit the damage of a shooting episode.

It is, to Australian ears, extremely odd that such an argument even has to be explained.  But we're not talking a normal country here. From another Salon article (worth reading in full):

Although the NRA has temporarily gone to ground, it’s no secret that its solution to this sort of gun violence is more guns. Indeed, chief spokesman LaPierre has made clear that he believes every American should be armed with a concealed weapon.  “Every American wife and mother and daughter, every law-abiding adult woman should be trained, armed and encouraged to carry a firearm for personal protection,” LaPierre told the NRA’s national convention, and he wasn’t trying to establish his feminist credentials.  LaPierre thinks every man in America should be packing heat as well.  The NRA believes that armed citizens in places like Newtown, Aurora, Tucson, Virginia Tech and Columbine can stop determined killers.  ”The presence of a firearm makes us all safer,” LaPierre said.  ”It’s just that simple.”

Whether or not a “responsible,” law-abiding adult trained in the use of firearms could make a difference in any particular situation is worthy of discussion.  Likewise the question of how to ensure that adult gun owners are responsible.  The problem is that the NRA and its congressional allies don’t want a rational debate about guns.  Two months after the 2011 Tucson rampage, which left six dead and 14 wounded, including Rep. Gabrielle Giffords, LaPierre rejected an invitation from President Obama to discuss ways of keeping guns out of the hands of criminals and the mentally unstable.  LaPierre said there was no point talking to “people that have spent a lifetime trying to destroy the Second Amendment.”  Following the Columbine High School massacre in 1999, which left 13 dead, the NRA urged a similar boycott of a meeting called by President Clinton to discuss ways of addressing teen violence.

The challenge today is not coming up with “the answer” to the nation’s gun violence; rather it is to move beyond the absurd but prevailing myth perpetrated by the extremists who currently run the NRA that nothing should be done because any effort to limit access to guns will lead to gun confiscation and tyranny.

When it comes to random mass shootings, Americans don't need protection from crims:  they need protection from the insane paranoia of the NRA and its supporters.

Update:  a good article here in Salon, citing lots of academics and their studies, on why more guns is not the answer.

The violent Hobbit

Peter Jackson's Violent Betrayal of Tolkien - Noah Berlatsky - The Atlantic

I don't intend seeing The Hobbit, but I am happy to note criticism of it.  

Given that my impression was that even Lord of the Rings movies graphically hyped  up the battle and slashing quite a bit compared to the books (which I haven't read fully - yes please just ignore me it attacking things I haven't seen really gets up your nose), this commentary in The Atlantic on The Hobbit sounds convincing:

Bilbo then (in both film and book) leaps over Gollum's head, leaving the creature despairing but unharmed. Later, in The Lord of the Rings, Gandalf suggests that Bilbo's pity for Gollum "may rule the fate of many." At the end of Rings, it is ultimately Gollum who, inadvertently, destroys the ring and saves Middle Earth. Mercy is ultimately salvation, and Bilbo's decision not to use violence is at the heart of the quasi-Christian moral order of Tolkien's world. 

If Jackson meant for Gandalf's comment to highlight Tolkien's nonviolent ethic, though, the rest of his film undercuts it—and, indeed, almost parodies it. The scene where Bilbo spares Gollum in the movie comes immediately after an extended, jovially bloody battle between dwarves and goblins, larded with visual jokes involving decapitation, disembowelment, and baddies crushed by rolling rocks. The sequence is more like a body-count video game than like anything in the sedate novel, where battles are confused and brief and frightening, rather than exuberant eye-candy ballet.

The goblin battle is hardly an aberration in the film. I had wondered how Peter Jackson was going to spread the book over three movies. Now I know: He's simply added extra bonus carnage at every opportunity. The dwarves, who in the novel are mostly hapless, are in the film transformed into super-warriors, battling thousands of goblins or orcs and fearlessly slaughtering giant wolves three-times their size.

Extraordinary Christmas house

On the weekend I took the family on the annual run around suburbs not too far from us to view Christmas lights.

But here is a little bit to illustrate, when the lights are co-ordinated with that classic Christmas song(?), the Chicken Dance:
