In praise of Sheldon
Despite the frequent sexual elements and jokes, I would say that the two funniest episodes I have seen concentrated on Sheldon and hence were pretty asexual. The first one was the story of how Leonard first came to move in with Sheldon, (The Staircase Implementation).
The second was on TV last night, featuring Sheldon deciding to stay safe in his bedroom until the singularity arrives and he can upload himself into a robot. In the meantime, he creates a tele-presence robot version of himself, which he get Leonard to drive to work. This sequence is currently on Youtube, and brought tears to my eyes.
Live long and prosper, Sheldon.
UPDATE: I am happy to see, from this recent LA Times episode review of the current season, that Sheldon's "girlfriend" Amy is still around. She has also been amusing me greatly in the couple of episodes I have seen in which she makes an appearance.

Slum life this is
The first of Kevin McCloud's 2 part doco "Slumming It," in which he spends a fortnight living with families in the middle of Mumbai's biggest slum, was great TV on the ABC last night. One minute appalled by the open sewer drains (full of mystery chemical sludge as well as excrement,) the visiting rats in the bedroom at night and the terrible working conditions in the mini industries in the slum, the next minute McCloud is marvelling at the apparent general happiness of the community and the high degree of social interaction of all age groups in such a place. (Well, the latter is kind of hard to avoid with things like 21 people sharing a tiny house. He also notes often that it is a million people living in about one square mile.)
As an architect, McCloud is interested in how the built environment works in a place like this. (He notes that many planners, and Prince Charles, have taken to saying that it has lessons to teach the West.) Yet the one factor he hasn't mentioned is the obvious high degree of religiosity of the people there, and the role that the degree of fatalism in the Hindu religion almost certainly has on the perception of the residents.
I also thought the show should be watched by the libertarian inclined as an object lesson in the limitations of self regulation of society. The industries there are completely unregulated and untaxed; a perfect little Randian experiment, I would have thought. And yes, the slum does show the inherent innovation and capitalist tendencies in self organised human societies. But it also shows that capitalism, at least in a culture such as India's, can be very slow to self correct for the abuses and poor treatment of its workers.
You can catch the show on the ABC’s iView still.
Salmon mystery
The BBC has a detailed story about the surprising strong return of sockeye salmon to their spawning rivers in Canada this year. Last year only a million came back; this year, 34 million!
The problem is no one understands what is going on.

Islamic news
* There’s always someone in the family who has an unusual conversion. Tony Blair’s sister in law has had a conversion experience in Iran:
She decided to become a Muslim six weeks ago after visiting the shrine of Fatima al-Masumeh in the city of Qom.
"It was a Tuesday evening and I sat down and felt this shot of spiritual morphine, just absolute bliss and joy," she said in an interview today.
When she returned to Britain, she decided to convert immediately.
I could be wrong, but sudden conversions to this religion seem pretty rare, unless you’re in an Indonesian prison. Seeing she’s a TV journalist, I would have been more amused if she had started to insist on an on screen burqa instead of just a hijab.
* There are two stories about men in legal trouble in the Middle East for using the internet for sexual purposes. An Egyptian Imam in Dubai is alleged to have sent rude pictures of himself to women via Blackberry (and was the victim of a “sting” by a male policeman posing as a woman). In Saudi Arabia a man who was making money by “renting” on line rooms in which women would strip is facing arrest.
I am curious: just how large are the cyberpolice departments in these middle east countries? If there are going to try to stop every man who sends a rude pic of himself from his mobile phone, they will be the biggest employment field in the region. And if these countries don’t block overseas sites, when will they realise there is no holding back the tide?
Suffer, snow bunnies
Look, if people grow up in a snowy country, skiing is an unobjectionable past time. But in Australia, where (if you live outside of Sydney or Melbourne at least) you can just about have 7 days in London (or, at the very least, a week in Tokyo) for the same price as a long weekend on the skifields, it’s always struck me as an elitist hobby. And besides, the couple of times I did try to stand up and move on skis, I fell over a lot.
So, being the jealous, nasty person that I am, if the Grammar school kids all end up with osteoarthritis, I’ll just snigger in the background.
Not your average Parisian evening…
There was a story in the SMH yesterday which is notable for the fine sense of understatement in the final line. First, I’ll edit the events (tragic as they are):
And the final line:A baby was killed and several more people seriously injured when a family of 11 threw themselves from a third-floor flat to flee a man they mistook for the devil, French investigators said….
Among the injured they found an entirely naked man of African origin with a knife wound in his hand and two children, a baby and a two-year-old girl. The baby died later after receiving hospital treatment in Paris.
The assistant prosecutor from Versailles, Odile Faivre, told reporters the incident began in the early hours when a group of 13 people were watching television in an apartment and the naked man heard the baby cry.
"The man got up to prepare a bottle for the baby when his wife, seeing him, screamed 'It's the devil, it's the devil'," Faivre explained.
In the confusion following this apparent case of mistaken identity, the naked man's sister-in-law stabbed him in the hand and he was ejected through the front door of the flat. When he attempted to get back in, panic erupted.
"The other occupants of the flat fled by jumping out of the window," Faivre said. According to police, one man jumped with the two-year-old in his arms and crawled two blocks away to hide in bushes, screaming: "I had to defend myself."
"A number of points remain to be cleared up," Faivre said.

Things of note
I’m going to be pretty busy this week, and really should try to impose a ban on myself using the internet. But such attempts usually fail, so you may as well keep checking in and seeing what turns up here.
This morning, I recommend the following:
* quite a good, long article in The Guardian on daily life in the nearly completed International Space Station. (They don’t dwell on the toilet, but you already know all about that from my earlier posts.)
* yet another tragic case of erotic autoasphyxiation actually ends up teaching medical science something new.
* GQ, of all magazines, has a long article on suicide chat rooms, and the coming trial of a guy charged with encouraging suicides. All very chilling, although the article also claims that some suicide chat rooms have positive effects and can help talk people out of it. But surely you would have to look at the net effect. Actually, I see Mind Hacks links to another story (this one from the BBC) about suicide chat rooms, but I haven’t listened to it yet.

Lunar greenhouse to nowhere
What a pity there's no way of actually getting them there for the foreseeable future. Maybe they should sell them to the Chinese.
More on Morals
I happen to think that the scientific study of morality is the lever that, if pulled hard enough, will completely dislodge religion from the firmament of our concerns.Why, yes, Sam, the first round of science's attempt to inform ideas of morality went just swimmingly well in the 20th century, didn't it?
Suicidal thoughts
* For once, he is not talking about sex and its variations, and I wish he would avoid the topic more often.

You knew you were going to read this
For example, we all know that rehearsing a set of words makes them easier to recall in the future, but what if the rehearsal occurs after the recall? In one of the studies, college students were given a list of words and after reading the list, were given a surprise recall test to see how many words they remembered. Next, a computer randomly selected some of the words on the list as practice words and the participants were asked to retype them several times. The results of the study showed that the students were better at recalling the words on the surprise recall test that they were later given, at random, to practice. According to Bem, practicing the words after the test somehow allowed the participants to "reach back in time to facilitate recall."There are other types of experiments as well. I see now that the actual paper is available, but at the moment I don't have time to read it.In another study, Bem examined whether the well-known priming effect could also be reversed. In a typical priming study, people are shown a photo and they have to quickly indicate if the photo represents a negative or positive image. If the photo is of a cuddly kitten, you press the "positive" button and if the photo is of maggots on rotting meat, you press the "negative" button. A wealth of research has examined how subliminal priming can speed up your ability to categorize these photos. Subliminal priming occurs when a word is flashed on the computer screen so quickly that your conscious brain doesn't recognize what you saw, but your nonconscious brain does. So you just see a flash, and if I asked you to tell me what you saw, you wouldn't be able to. But deep down, your nonconscious brain saw the word and processed it. In priming studies, we consistently find that people who are primed with a word consistent with the valence of the photo will categorize it quicker. So if I quickly flash the word "happy" before the kitten picture, you will click the "positive" button even quicker, but if I instead flash the word "ugly" before it, you will take longer to respond. This is because priming you with the word "happy" gets your mind ready to see happy things.
In Bem's retroactive priming study, he simply reversed the time sequence on this effect by flashing the primed word after the person categorized the photo. So I show you the kitten picture, you pick whether it is positive or negative, and then I randomly choose to prime you with a good or bad word. The results showed that people were quicker at categorizing photos when it was followed by a consistent prime. So not only will you categorize the kitten quicker when it is preceded by a good word, you will also categorize it quicker when it is followed by a good word. It was as if, while participants were categorizing the photo, their brain knew what word was coming next and this facilitated their decision.
The effect was apparently small but statistically significant and consistent, and also showed that some people showed stronger future influence than others.
Well, this is all pretty fascinating, isn't it? It would be great if this type of experiment can be repeated and holds up over time in different labs. Until now, I think it's fair to say that Ganzfeld experiments have been held up as the most convincing proof of a psi effect, as they have been repeated in many different labs and generally been considered to show small but positive results. (A good detailed history of this type of experiment, and the controversy over whether they really are showing a psi effect or not, is given in this Wikipedia article.)
However, as the examples that Dean Radin has been providing at his website lately show, there is always an element of interpretation involved in scoring the "hits". (In fact, in this example Radin gives of someone trying to guess the correct photo, what I find surprising is that all 4 photos seem to have elements the woman is "receiving", even though the "sender" only sees the target.) But clearly, it would be great to get away from experiments that involve interpretation of what constitutes a "hit" in proving a psi effect.
Of course, we are yet to hear the skeptic take on the new Bem studies, and I guess we do have to wait to see if other psychologist can replicate them, but they sound rather promising.

The origins of morality considered
There are many things that could be said about this topic, but I don't have the time right now.
It did come to mind when I was watching the second episode of Last Chance to See on Sunday night, when they were showing two orphan chimps being introduced to a new chimp group. You can watch the clip here. The evolutionary aspect of human bonding and how touching we find it is illustrated well.
Can the sensible one come back now, please?
Has anyone else noticed how, while Tony Abbott has been doing things like travelling the world, shooting off guns and his mouth, and changing his opinions more often than a Japanese astronaut changes his underwear, Malcolm Turnbull has been doing things like, well, making sense.
Yesterday it was his proposal to force the government into the proper investigation into the financial viability of the National Broadband Network. Today, it’s an article emphasising the importance of spending money to get irrigation in the Murray – Darling system water efficient.
On the latter, I’ll admit it’s an issue I have not followed in detail, and it does appear to be both a scientifically and politically complicated one. As far as I can tell, the Coalition is saying that Labor pulled back spending on water efficiency and is now wanting to concentrate purely on water buy back, but I could have that wrong.
During the angry scenes of rural meetings last week where the idea of 30% water allocations was going over like a lead balloon, the thought did occur to me that if we are talking of inefficient irrigation still existing on many of those farms, is it possible to still get the same yields with the lower allocation being compensated with increased efficiency in delivery? Has the relevant body had Israel involved in how to grow stuff with minimal water?
Probably all this has been taken into account, but there’s no harm in asking.

Local hero
Maybe he’s had some media attention here before – but if so I’ve missed it.
In any event, here’s the great story (in the Christian Science Monitor) of an old guy who has almost certainly saved a great many people from committing suicide at The Gap in Sydney.
Even when he has failed, it hasn’t deterred him from continuing to approach people he fears are about to jump and invite them in for a cup of tea. He’s a real hero for many, many families, I am sure.
Give up, climate change skeptics! Kirk is against you.
Important news from Climate Progress. (Even more important than 2010 being the hottest year on record so far, and the long list of countries that last link provides which have broken high temperature records this year.)
William Shatner is an environmentalist! And he does ads for Sierra Club which sound rational and credible.
You know your on the losing side when Cap’n Kirk is against you.

Stellar mysteries
Two unusual stories of stars were in the news last week:
1. a pulsar discovered that doesn’t seem to have the right type of surface magnetic field for the way pulsars are normally meant to work. This means there is a bit of work to be done to see how this type of pulsar gets its power. (My comment: first alien artefact found?)
2. the Milky Way seems to have kinks in its arms, making it a bit more like a pinwheel than your usual Andromeda galaxy, curvy armed, classic shape. Other galaxies that look like this have been seen before, so this is not considered completely weird, apparently.
But – how does any galaxy get angles in arms like that? I would have thought that nature (and gravity in particular) loves circles and curves. Odd.

New nuclear designs considered
There’s a really good article in Physics World from 1 October that discusses the “next generation”designs for nuclear reactors in a pretty straight forward fashion.
There are several paragraphs devoted to the pebble bed, noting this in relation to the recently ended South African program:
Opinion is divided on the significance of the South African project's termination. Stephen Thomas, an energy-industry expert at the University of Greenwich in London, calls it a "major setback" for the development of very-high-temperature reactors, since, he says, South Africa's efforts appeared to be more advanced than research being carried out elsewhere. However, Bill Stacey, a nuclear engineer at the Georgia Institute of Technology in the US, disagrees with this assessment, adding that South Africa was "just one of many players and not one of the major ones". China, Japan, France and South Korea are also developing technology for high-temperature reactors, some of which is also designed to use pebbles.
For its part, the US is pursuing a variant of the pebble-bed design known as the Next Generation Nuclear Plant (NGNP). Intended to reach temperatures of 750–800 °C, the NGNP will allow for different fuel configurations, with the coated fuel kernels held either in pebbles or hexagonal graphite blocks. According to Harold McFarlane, technical director of GIF and a researcher at the Idaho National Laboratory, the US Congress approved the construction of a prototype NGNP in 2005 but has so far awarded funding only for preliminary research and development.
Spring sprung
It’s traditional at this blog at this time of year for some photos to appear from the garden. This has taken longer than usual to happen in 2010, due to the very unseasonably wet and grey weather Brisbane has had for the last 6 weeks or so.
But, today is sunny and nice, the grass has already been mowed, and here are some photos from this morning:

Open access to climate change material!
I see from the Nature website that Martin Weitzman has a review of Lomborg's latest book. Yet it is behind a paywall and would cost $32 (!) to get the article. There are also a couple of studies reported about the role of CO2 as the key greenhouse gas. One is in Science, behind a paywall (but available here via a skeptic site!), the other "companion" study one will be coming out in a different journal, and will almost certainly also be paywalled.
Routinely, important new papers on climate change (and ocean acidification) are behind paywalls. If you're lucky, sometimes bloggers or others made a .pdf of the article available.
Look, if those who edit and own the major scientific journals feel that climate change is a serious forthcoming threat for the whole of humanity which is capable of a political response now to modify the threat, why don't they adopt a policy of making such material in their journals available for free? It would be a modest but important attempt to make important material available to the public, who are, after all, pretty damn important in the political process.
If they say they can't do it financially, ask governments, or Bill Gates, or Google, to cover the (surely modest in the big scheme of things) cost of doing this.
I'm sick of this current system on the biggest scientific/political issue that we've ever seen.
