Pigs in history

Good food: Nose-to-tail eating | The Economist

From this review of a book about pigs in history:
The curly-tailed animals have proven extraordinarily useful to human development and have been present from the earliest permanent dwellings to modern metropolises. The porcine ability to turn waste of almost any description into protein—thanks to “a simple gut and multipurpose
teeth”, which means it can eat almost anything—ensured that in the ancient Near East, Anglo-Saxon England and the Americas it was theperfect beast to sustain rapidly growing and colonising populations.

Yet the pig’s indiscriminate appetite has also been its worst enemy. Not for nothing is there a Chinese character, qing, that designates both “pigsty” and “outhouse”, and the idea of consuming a beast fed on communal waste has appalled societies from the ancient Egyptians to the Jews and 19th-century New Yorkers. Pigs have also been beset by snobbery, given that pork has regularly provided calories to the poorest members of society. After the Black Death carried off a third of Europe, demand for meat plummeted and so did prices. Peasants
started eating pork; uppity nobles chewed on birds and beef instead.

Mr Essig’s main point is that the better people treat pigs, the more they like them. Romans lavished love and attention on their pigs, allowing them to wander in the woods, eating nuts and grains. In return, they enjoyed delicious meat. Post-war America industrialised pig production, inventing indoor cages and “a litany of horrors” for their sows, and found the meat was mushy and tasteless. As a consequence, pork consumption has been static for 30 years.

Amateur philosophy and the superhuman

The moral imperative to research editing embryos: The need to modify Nature and Science | Practical Ethics

I see via Jason Soon that there is a bit of a push back against the backlash in Nature and Science about the Chinese who conducted gene editing experiments on (non viable) human embryos.  The article above is one of them.

Now I understand, to a degree, their complaint that the Chinese research was not on viable embryos, so there was no risk of harm in that particular experiment.  And if anything, its results serve as a warning that such editing is not reliable enough to try on viable human embyros, so in that sense it could be welcomed as showing that the dangers from trying to do such work are real.

However, it is pretty clear that the defenders go further - they actually want to see human genome edited for improvement, seeing it as our science fiction-y, transhumanist destiny.   The rest of us are sticks in the mud (probably Christians) standing in the way of progress.   All very Nietzschean. 

But you really have to wonder about the dubious way the guys who wrote the article linked above deal with the question of responsibility in this paragraph:
Imagine that I am a scientist. I have a promising candidate treatment
that could save the lives of 30 million people per year. I decide not to
continue the research. I am responsible for the deaths of those 30
million people if my research would have led to a cure.
This is just a silly attempted extension of the concept of  "responsibility" if you ask me, and reeks of amateur, late night bar room philosophy.   How could they have left that line in and not expect it to detract from their credibility?

The desire to improve humans developmentally is not per se wrong - ensuring adequate nutrition and vitamins for mothers to prevent avoidable problems is a good thing.  But the obvious solution to eliminating the worst genetic disorders is by either not having babies at all once it is discovered you are carrying a dangerous gene, or at least screening embryos for the defect.  Neither carries the risk of inadvertent harm caused by what is likely to be the inevitable imprecision of seeking to repair individual genes, and it's not as if humanity doesn't have enough healthy gene lines to keep the species going.

As for the desire to improve the germ line - you're a philosophical amateur if you can't acknowledge the ethical question it raises as to which human qualities deserve enhancement or removal.  

All was revealed

I woke up this morning from an odd but not unpleasant dream, which initially featured zombie like re-animated dead people (they could talk but not move much) who basically appeared puzzled as to why they were alive again.  To one of them talking about death, I made a comment along the lines that matter may eventually disappear, but information is never lost.  He scoffed at the suggestion, saying that he couldn't see how that made sense, as you needed matter to encode information.

Dream-me then had some exciting insight into information leaking into another universe, and the idea that other universe information watchers became the people who decided what was moral or not in this universe.  I ran off somewhere in a dream Brisbane to write it all down, but someone rudely suggested it might just be a good plot for Dr Who.

I have the feeling seafood somehow got involved too.

Anyway, I woke up to think for a while if there is any theory floating around that does involve information never being lost.  (I keep remembering a line from Spielberg's AI when I think about this.)

I then watched David Leyonhjelm (or his missus) brushing a cat.

More American right wing paranoia

Paranoia Strikes Derp - NYTimes.com

Paul Krugman brings to my attention some current Right wing nuttiness in America, that the dim Ted Cruz is prepared to entertain, at least to the extent of asking the Pentagon about it.  (I bet they're impressed with the idea of him as a possible boss.)

A good case

Coalition economic agenda is crony capitalism | Crikey

I don't always agree with BK, but I reckon he makes a reasonable case here.

Good TV

Two great shows on the ABC last night:

Foreign Correspondent visited King George Island, at the northern top of Antarctica, and which has several national research bases.  (I had posted a photo of its "what's that doing here?" Russian Orthodox church a few years ago.)   Eric Campbell spoke to scientists, all concerned about climate change and the clear melting it is causing in that part of Antarctica, and talked about the international co-operation in that part of the world.   A fascinating show all around.

*  Griff Rhys Jones is making his way through Africa - by train.  (! Didn't realise there were many trains to try there.)  Last night's show, up on iView for now at least, had him starting in Morroco and making his way to the east, while having to cross disputed borders by jumping back to Europe. (! again.)

Travel shows rarely visit Northern Africa, apart from Marrakesh perhaps, so it was a great surprise to learn that the French had built some pretty fancy train lines and stations, and much of the countryside of in that part of the world looked pretty attractive.

The city of Fez in Morocco looked fascinating, but the biggest surprise was the remarkable appearance of the city of Constantine (in Algeria), built around a huge gorge.  As this article says, it may be the most beautiful city you've never heard of.  Pity the show didn't spend more time there...

Avengers backlash stronger than I thought

Who is this Jason Wilson who writes at the Guardian, and why does he look sort of like an aging daggy hipster but without the beard?

Anyhow, he spends a lot of time complaining about the Marvel franchise in light of Age of Ultron, which saves me doing it.   (Well, not that I can do it well, seeing I am not going to see it.)

Elsewhere, I see that a conservative Catholic priest complains about the movie in a post with the title ''The Avengers'' and Friedrich Nietzsche".

That said, I'd still see a Guardians of the Galaxy sequel if it gets good reviews.

Update:  and still it comes!  I had missed the iO9 "Hater's Guide to Avengers: Age of Ultron".   The lameness of the (apparently) recurring glowy cubes is dealt with here:
Nearly every Marvel movie has had one of these f**king glowy cubes or gems or eggs or whatever, and they’ve all contained an Infinity Gem, which means quite a bit to longtime comic readers, but I have to guess next to nothing to anyone else beyond, “Jesus why are all these movies about cosmic jelly beans?” Anyway, lots of Infinity Gems, and we’re going to get a whole TWO PART space-Avengers movie, and it will probably be cool, but if you follow the logic of the after-credits scene with Thanos saying he’ll just go do it himself ... what the f**k has he been doing? This guy has just been sitting on a space rock for like four movies now sending other, clearly incompetent dipshits around to zero effect! The guy in Guardians of the Galaxy even told him to eat shit once he got an Infinity Gem, and Thanos didn’t do shit about it! Is Thanos even going to be that hard to fight? Like, how does he do cardio on that lil asteriod? Thor in 8.
The only surprise to me is that it has taken this long for people to realise that comic book superhero stories just aren't that good.

Not mentioned in polite company anymore

I guess the free travel and accommodation paid for by mining billionaires and mystery funded "think tanks" has dried up, so former climate change denier guest speaker Christopher Monckton may feel free to be more open about his conspiracy thoughts:

Slow science

Warm oceans caused hottest Dust Bowl years in 1934/36

This seems to makes sense, given that California has been hot lately with a large pool of warm water off its coast.

But why has it taken so long to look at this with respect to the unusually warm years in the 1930's.  (Or has it already been done in other studies, and this is just inadequate science reporting?)

Pot windfall skepticism

Interesting article in The Atlantic expressing skepticism that one of the key selling points for legalising marijuana in Colorado (raising money needed for schools) is likely to work as advertised.

Amusingly, part of the problem is something that sounds like one of those Tea Party/libertarian inspired "let's stop the government getting a cent more than they should" ideas:
What's more, in an awkward (and perhaps embarrassing) twist, all that money could be lost. That’s because, under Colorado’s “Taxpayer Bill of Rights,” if in any given year the state reaps more tax money than revenue forecasters had projected, the state must return that extra revenue to taxpayers. This year, the provision will be triggered because—even though the pot money came in lower than expected—the state collected more tax revenue overall thanks to other industries such as energy and oil. Lawmakers are now crafting a bill that would ask voters this fall to approve an exemption to that provision for the pot tax.
Down in comments, someone makes what I think might be a pretty good point:
A legal market in pot never mattered that much to me. It's absurdly overpriced, considering that it can be easily grown in personal-use quantities. The important thing is to allow legal possession of reasonable quantities (a few plants, a few ounces), legal non-profit transfer and gifting between adults, legal seed sales, and home cultivation. Like household brewing of beer and wine.
Two things I don't want: legal pot as a commercially advertised product on broadcast media, and government dependent on pot as a revenue source. Marijuana is better off as something that's low-key, discreet, and no big deal. It's also better off as a negligible expense, which puts more disposable income into the hands of people who can spend it on something other than a non-poisonous, non-invasive annual weed that's easily cultivated in a few square feet of space, either indoors or outdoors.
 Yes.   It seems to me that a major part of the legalisation problem will be from allowing capitalists to actively promote the market for a substance which the government really has an interest in limiting.

Battery power revolution?

John Quiggin thinks the Tesla domestic battery story is very big indeed.

Nature has a much more conservative take on it.

The truth perhaps lies somewhere between.

China and drug use

'Breaking Bad' in China: how meth is spreading across rural heartland - CSMonitor.com

This is a good report about illicit drug use in China.

I didn't realise that even in that country, a substantial change towards harm minimisation has been underway for nearly a decade:

Since 2006, the Chinese authorities have tackled heroin abuse by decriminalizing the drug’s use and opening nearly 900 methadone clinics to wean addicts off it. But no drug like methadone that would help methamphetamine users break their habit has been found, so no such medical approach has been possible.

Some caught using meth are encouraged to attend voluntary detoxification centers; most – especially if they are caught a second time – are sent to compulsory detox facilities in former prisons and held for as long as two years with no judicial or medical intervention.
Methadone programs have been available across the West for decades; clearly, it is even pretty widely used in the US too.

Libertarians, who like slogans and fantasy more than working out the detailed solutions to real, complicated issues, continually use the "war on drugs - oh my God it's a complete failure!" line while ignoring the fact that it seems nearly all nations incorporate a harm minimisation approach to at least this major illicit drug.  (Well, I guess, if they can afford it.   I don't imagine much is available in somewhere like Afghanistan.)

Legalising highly addictive drugs is always going to be problematic, because the costs of addiction at individual, social and economic levels are always likely to be high.

But let's just chant "we have to end this War on Drugs" and leave it there, shall we?

US 'will not fund research for modifying embryo DNA' - BBC News

As it says at the end:

Dr Collins, who was also a key player in the Human Genome Project, released a statement saying: "The concept of altering the human germline in embryos for clinical purposes has been debated over many years from many different perspectives, and has been viewed almost universally as a line that should not be crossed.

"Advances in technology have given us an elegant new way of carrying out genome editing, but the strong arguments against engaging in this activity remain.

"These include the serious and unquantifiable safety issues, ethical issues presented by altering the germline in a way that affects the next generation without their consent, and a current lack of compelling medical applications."

Dr Marcy Darnovsky, from the Center for Genetics and Society in the US, argued: "There is no persuasive medical reason to manipulate the human germline because inherited genetic diseases can be prevented using embryo screening techniques, among other means.

"Is the only justification for trying to refine germline gene editing the prospect of so-called enhancement?"

Music video time

So, it seems to have been around for 6 months, but I only recently saw this simple but amusing video clip from George Ezra (and friend):


South East Queensland and rainfall intensity: so this is what global warming looks like?

Rainfall statistics can be analysed any number of ways, and it seems to me that intensity of rainfall is one of the things that has become very important but is being investigated a bit too slowly. 

My strong, strong hunch is, however, that at least South East Queensland (if not other parts of the country) is now clearly undergoing the type of intensification of rainfall that was always expected under global warming and is suffering badly for it.  

Last Friday's rainfall was deadly, remarkable, and unseasonal across most of the South East, but particularly just to the north of Brisbane.   It reminded me of the intensity of rainfall that led to the Lockyer Valley disasters in the 2011 floods - where all forms of normal drainage (and Brisbane's drainage is built to sub-tropical standards) is so overwhelmed  that the flood is disastrously out of the norm in terms of suddenness of onset.    

But I'm not sure whether we are getting a good analysis of this in a timely fashion.

See, while it's interesting that a daily rainfall total might be a record for the time of year, I don't know that this captures the importance of the hourly intensity of rainfall adequately.

There may well be some academic papers on this around the place, but if so, it seems to me it is not attracting adequate publicity via the Bureau of Meteorology.  (Although I think the public knows something is going on.)

Alternatively, I could be wrong and the intensity is not out of the norm in historic terms.   I very much doubt that is the case, however. 

Update:  my point was alluded to in this article in The Conversation (my bold):
The problem is: “How can we estimate the frequency of rare extreme events from observations, or events that we are yet to witness, such as a 1-in-500-year event?” To solve this problem we need to model the data and use it to extrapolate outside our observations.
When we’re talking about flash floods and extreme rainfall, we want to know the highest rainfall in a single day or in a few hours, rather than total rainfall over longer periods such as a month or year. The best long-term rainfall observations are for daily rainfall.

1930's naughtiness update

Last week, on a whim, I was using Trove to find early Australian newspaper references to nudism, and turned up a series of stories from 1929 and into the 30's indicating the interest the topic attracted in Australia and the US.  

Today I Googled to see if a Pope had ever weighed in on the matter, and indeed, a 1930's Pope (Pius XI) did*:


That lecture seems a little late - the newspaper clippings I had in my previous post show that in 1932 and 1933 (the latter after Hitler had taken power) Germany was already banning the "cult of nudity".

But more interesting was an extract I found from an article about the future Pius XII, the wartime Pope, before he took on the top job:
In 1926, Pacelli was Vatican ambassador, or nuncio, to Germany, and he alerted Rome to the “moral perils” confronting Catholics in the freedoms of Weimar democracy. “Perhaps the thorniest problem for religious life and pastoral care,” he wrote, was Germans’ propensity to use contraceptives and have abortions. He railed against the “perverse propaganda of nudism,” and against the Tango, which was “of very evil origin.” “Any gymnastics wear for girls,” he continued, “that proactively accentuates their shapes or that is inappropriate for the female character must be avoided.”
Germany had just experienced the greatest cataclysm since the seventeenth century, and Berlin was a place where impoverished shopkeepers queued at soup kitchens while disfigured veterans asked for handouts on street corners. Working class families lived six to a room. But what bothered Pacelli were girls’ gym clothes. Pleasure and license posed a danger to eternal salvation, but poverty did not.
I didn't realise the concern with which the Tango was held in the early 20th century.  

In an interview published three years ago, the then Cardinal Bergoglio said of the tango, ‘I like it a lot. It’s something that comes from within me.’ He showed great knowledge of the tango’s history and of its most famous performers, especially mentioning Ada Falcón, an Argentine tango singer and actress of great wealth and celebrity who, 60 years before her death in 2002, suddenly gave up a life of luxury and romantic turbulence to live in seclusion in Buenos Aires.
Times change...

What is it about the eyes?

Through This Chemical Loop, Dogs Win Our Hearts – Phenomena: Not Exactly Rocket Science

Well, given our dog's death last weekend, it seems apt to post about this recent story, which reported both humans and dogs getting an oxytocin boost from even just looking at each other.

This puts me in mind of the "how to fall in love" story from earlier this year - which ends with silent staring into each other's eyes.

I'm finding it rather odd that it is eye gazing in particular which seems to have powerful binding effects.  

Peak superhero?

Hmmm.   Of course, I've been hoping for this for years, and with the amount of money they make, there is really no reason for optimism.   But - with Avengers: Age of Ultron getting a relatively modest 73% on Rottentomatoes, I at least get the feeling that critically, we may have reached, and passed Peak Superhero.

The common theme amongst those critics who are underwhelmed is that the climatic, city wide destruction fights are all looking very same-y these days.   How true. (Well, I think, since I only get to view them in bits in pieces when they show up on free to air TV a few years later.)

Anthony Lane writes one of the wittiest reviews of the movie, with sections like this:
The story begins with a fight in a forest and ends with a fight in a city that floats in midair. In between, there is a fight in a castle, a fight on a freeway, and a fight in the wake of a cocktail party. The loudest fight is a tussle between Iron Man and the Hulk, which is part of a cunning scheme to rip the Avengers apart. Bring it on, I say. It has something to do with dreams, which are triggered by a blast of hypno-magic from the Scarlet Witch (Elizabeth Olsen), a new player in the game; each hero is disabled by harsh visions, tailored to touch upon his or her worst fears. I vaguely hoped that Thor would find himself holding hands with Hello Kitty, but no joy.

The experience of watching “Avengers: Age of Ultron”—which is not just long but, in Iron Man’s words, “Eugene O’Neill long”—runs as follows. First, you try to understand what the hell is going on. Then you slowly realize that you will never understand what is going on. And, last, you wind up with the distinct impression that, if there was anything to understand, it wasn’t worth the sweat.
By the way, showing that he's not just a humourist, Anthony Lane writes well about Gallipoli in another piece inspired by ANZAC Day (and the movie "The Water Diviner".) 

Gerard backed a loser

Dissembling with graphs: Murry Salby edition | Musings on Quantitative Palaeoecology

Further to my suggestion that Gerard Henderson retire, remember that it was his Sydney Institute which first gave a public airing of Murry Salby's late life crisis in which he had decided that CO2 had virtually nothing to do with increasing global warming in the 20th century.

Of course, most in Gerard's audience couldn't really follow what Salby was arguing; those who read climate blogs saw that all other scientists immediately recognised that his argument made no sense at all. He lost his Australian job before it had really started, over some dispute or other about its terms. I see that Salby didn't even make into the IPA's latest bit of effort to promote crap about climate change. 

Anyhow, just in case anyone thought he was a misunderstood genius, have a look at the post above for some stunning examples of deceptive material he now presents at talks that he is apparently still giving. Amazing.

A fast food and diet observation

It seems years since I've eaten chicken pieces from KFC.  The occasional burger, yes.  But pieces of chicken, no.

But two nights this week, I've eaten cold KFC chicken.  (I got home late, that's all.)

I found it nicer than I remembered.  Much nicer.   Not very greasy, really.  Especially as it was cold.  I sometimes think I prefer cold chicken to hot.

It might also be partly because of being on a 5-2 diet.  It seems to heighten appreciation for the taste of food, even on a non fasting day.
