Fish oil, part 2

Fish oil 'reduces youth psychosis'

After recently posting about the benefits of fish oil for adults who want to slow aging, this news of another (somewhat unexpected) apparent benefit of it for the young is worth noting:

In the study, published in the Archives of General Psychiatry journal, 41 high-risk patients were given four fish oil capsules a day for three months. Only two of them developed a psychotic disorder, compared with 11 of another 40 who took a placebo...

High-powered anti-psychotic drugs can come with metabolic changes, sexual dysfunction and weight gain which are often not acceptable for young people, leading to high drop-out rates.

Very few people dropped out of the fish oil treatment regime, and a 12-month follow up showed the effect seemed to protect the brain even after the patient stopped taking the pills.

What isn't it good for?

Clarification on that water vapor story

The role of stratospheric water vapor in global warming

Yet again, John Cook does a clear and enlightening post on that "less water vapour in the stratosphere" story I posted about below. Bottom line:

There seem to be two major misconceptions arising from this paper. The first is that this paper demonstrates that water vapor is the major driver of global temperatures. In fact, what this paper shows is the effect from stratospheric water vapor contributes a fraction of the temperature change imposed from man-made greenhouse gases. While the stratospheric water vapor is not insignificant, it's hardly the dominant driver of climate being portrayed by some blogs.

The other misinterpretation is that this paper proves negative feedback that cancels out global warming. As we've just seen, the magnitude of the effect is small compared to the overall global warming trend.

iWant - I don't

Charlie Brooker | iPad therefore iWant? Probably. Why? iDunno

Charlie Brooker has some good cynical lines about the iPad. This is probably the best bit:

Apple excels at taking existing concepts – computers, MP3 players, conceit – and carefully streamlining them into glistening ergonomic chunks of concentrated aspiration. It took the laptop and the coffee table book and created the MacBook. Now it's taken the MacBook and the iPhone and distilled them into a single device that answers a rhetorical question you weren't really asking.

On a more serious note, it seems to me that Apple's failure to get on with Adobe (so that Flash content will not show on the iPad) is a very big reason not to buy an iPad:

In a blog post last week, Adobe group manager Adrian Ludwig railed against iPad and restrictions on Apple devices "that limit both content publishers and consumers".

"Without Flash support, iPad users will not be able to access the full range of web content, including over 70% of games and 75% of video on the web," Ludwig wrote.

This limitation does not apply to the games and other content available through Apple's App Store, as these apps are coded specifically to suit Apple's devices.

On the unofficial TheFlashBlog.com, Adobe platform evangelist Lee Brimelow provided several screen shots showing examples of web content that would be unavailable on the iPad, such as parts of CNN.com, Farmville.com, video streaming websites such as Hulu.com, porn sites, graphics on Google Finance, web games and much of Disney.com.

Here's a pretty compelling extract from a book looking at Europe's dwindling birth-rate and aging population. (The situation with emptying towns is already very dire in East Germany, apparently.)

Red faces

Did rice wine lead to flushed faces in Asia? - New Scientist

As it happens, today I witnessed this first hand. I convinced an Asian friend, who assured me he did not often drink alcohol because of the severe face flushing it causes him, to at least try a Cascade Premium Lite. (Alcohol content: 2.6%.)

It was still enough to cause a very noticeable flush. It did seem to fade by the end of the schooner, though, but he wouldn't take up my suggestion that he now try a full strength beer to see if he had broken some sort of barrier.

The science behind it is explained in the New Scientist article as follows:

A mutation that causes some Asians to flush red when they down a beer may have evolved to help their ancestors cope with rice wine. A genetic study suggests that the mutation evolved around 10,000 years ago, about the same time as Asians were starting to farm rice and figuring out how to ferment it into boozy drinks....

The mutation causes alcohol to be metabolised at 100 times the speed that it otherwise would be. As the enzyme removes alcohol so quickly from the blood stream, it protects people from the harmful effects of alcohol, and Su believes it confers an evolutionary advantage: a study in the Han Chinese suggests that those carrying the mutation have the lowest risk of alcoholism (American Journal of Human Genetics, vol 65 p 795).

The mutation also causes a by-product of the alcohol's metabolisation to accumulate in the body, which makes those who have the mutation flush red when they drink.

So, this mutation has the embarrassing effect of making you look like a quick drunk, which (like my lunch mate) causes some sufferers enough embarrassment to not want to drink at all, but actually it sounds like they should be capable of drinking with relative impunity. How ironic.

School tables

ABC The Drum Unleashed - Julia Gillard: a political dill

So, it turns out that Bob Ellis can't stand Julia Gillard and criticises everything she has ever done. I'd guess that there is some personal history there that Ellis is not revealing.

But on the point of ranking schools, which Ellis disagrees with, someone in comments makes the point that a friend (a former teacher in fact) made to me on the weekend. That is, it's the private schools that might have a lot to lose in this. The Myschools site makes it easy to check how much value you might be getting for sending your kid to an expensive school, and it may not be as good a deal as expected.

Typical Democrats

Apart from the original race to the Moon being a Democrat initiative, it seems that since the 1970's, Democrat Presidents have only ever been about cut backs and bad news for the American space program. This tradition is, as I pretty much expected, continuing under Obama with this annoucement that the manned space program is going to yet again be stuck in low earth orbit indefinitely.

They (Democrats) seemingly have no vision about the future at all. I mean, does anyone feel that Obama actually has any daring in his approach to the energy future of the US or the world?

Bah.

The silence of the planets

I didn't realise Frank Drake, who kicked off the idea of SETI, was still alive.

But he recently spoke at the Royal Society and explained that changes to broadcast technology is making the earth harder to hear from afar:

"The trouble is that we are making ourselves more and more difficult to be heard," said Dr Drake. "We are broadcasting in much more efficient ways today and are making our signals fainter and fainter."

In the past, TV and radio programmes were broadcast from huge ground stations that transmitted signals at thousands of watts. These could be picked up relatively easily across the depths of space, astronomers calculated.

Now, most TV and radio programmes are transmitted from satellites that typically use only 75 watts and have aerials pointing toward Earth, rather than into space.

"For good measure, in America we have switched from analogue to digital broadcasting and you are going to do the same in Britain very soon," Drake added. "When you do that, your transmissions will become four times fainter because digital uses less power."

"Very soon we will become undetectable," he said. In short, in space no one will hear us at all.

What is true for humans would probably also be true for aliens...

I have a vague recollection of Arthur C Clarke also saying that this would happen. Mind you, I am not entirely sure it is a good idea to make your presence known in the universe, so a bit of quiet from planet Earth might be a good thing.

It is complicated

Water vapour could be behind warming slowdown : Nature News

This article talks about a new suggestion that a drop in stratospheric water vapour might account for a (relative) levelling out of global temperatures in the last decade:

...a team led by researchers at the National Oceanic and Atmospheric Administration (NOAA) in Boulder, Colorado, report that a mysterious 10% drop in water vapour in the stratosphere — the atmospheric layer that sits 10–50 kilometres above Earth's surface — since 2000 could have offset the expected warming due to greenhouse gases by roughly 25%. Just as intriguingly, their model suggests that an increase in stratospheric water vapour might have boosted earlier warming by about 30% in the 1980s and 1990s. The team's work is published online by Science today¹.

The effect on temperature is dominated by water vapour in the lower part of the stratosphere, which absorbs and radiates heat in much the same way as water molecules and other greenhouse gases do in the lower atmosphere. The drop in water vapour doesn't explain the entire decrease in the rate of warming, but it could contribute to it, says Susan Solomon, first author of the study

It all seems a very tentative idea though:

Other researchers see different factors at play in the recent temperature trends. A study published last year³ hones in on the solar cycle and the El Niño Southern Oscillation, an upwelling of warm surface waters in the tropical Pacific. Both have been in their negative phases for most of the decade so temperatures may rise as they move into their positive phases.

"I think it's exciting that this [transition] is happening, because we are going to learn a lot," says Judith Lean, a solar physicist at the Naval Research Laboratory in Washington DC, who co-authored last year's study³ with David Rind, a climate modeller at NASA's Goddard Institute for Space Studies in New York.

The article seems to indicate that no one knows what water vapour in the stratosphere will do in the future.

Other researchers think current models account for the occasional decade long stall in increasing temperatures and it's not a good idea to worry too much about the issue anyway.

You can bet, however, that skeptics will seize on this paper, with their attitude that if something is not completely understood, you don't do anything about it. Which is, by most scientists reckoning, a good way to gamble on potential long term disaster.

Australian bees visit

It's been a while since a photo appeared here, so let's put one up.

The kids noticed these bees in the garden in December. They have unusual behaviour, clinging to a particular stick on a bush overnight, and disappearing again during the day:



It appears that they are Australian blue banded bees. They are solitary (in that they don't build hives), but like to sleep together in small groups. Apparently they are common around Brisbane, but I've not noticed them before. Nice.

All that took 60 seconds?

Well that was sort of humiliating.

I've been blogging for nearly 5 years now, but never got around to downloading a back up copy of it, just in case Google somehow forget who I was or lost all of this valuable(?) work.  (I'm not read enough to be hacked, I figure.)

Anyhow, doing an export of the blog to a hard drive from Blogger is now very easy, but it saves it in a .xml format which doesn't (I think) save photos and just leaves the bones of the blog to be recreated later if necessary.  (I think.)

So I decided I would also download a mirror copy of the site onto my hard drive, using the very handy WinHTTrack Website Copier.  (I haven't used it before, but it worked fine.)  That way it looks exactly the same on my hard drive as it does on the web.

I assumed that this program going back through Blogger and downloading every post and photo would take, I dunno, at least 10 minutes.   Five years of writing and effort should not be able to be downloaded too quickly.

Well, I swear it took less than 60 seconds to finish.  I'm feeling slightly depressed now.

A novel suggestion

The Moon may have formed in a nuclear explosion:

The hypothesis (credited to Charles Darwin’s son George in 1879) is that the Earth and Moon began as a mass of molten rock spinning rapidly enough that gravity was just barely greater than the centrifugal forces. Even a slight kick could dislodge part of the mass into orbit, where it would become the Moon. The hypothesis has been around for 130 years, but was rejected because no one could explain a source of the energy required to kick a moon-sized blob of molten rock into orbit.

Dutch scientists Rob de Meijer (University of the Western Cape) and Wim van Westrenen (Amsterdam’s VU University) think they know the answer. Their hypothesis is that the centrifugal forces would have concentrated heavy elements like thorium and uranium on the equatorial plane and at the Earth core-mantle boundary. If the concentrations of these radioactive elements were high enough, this could have led to a nuclear chain reaction that became supercritical, causing a nuclear explosion.

Would have been good to watch.

A reasonable fear of lightning

People who know me well know that I am, to say the least, a touch on the sensitive side when it comes to storms and the danger of lightning. A brother says I am completely unreasonable about this; I argue that it is completely justified, and based on my broader than average reading of the strange ways lightning has killed or injured people.

For example, I know that is not a good idea to be near open windows during lightning storms. Yet people complain when I immediately start shutting windows as soon as I judge the storm is close enough. (Sometimes I can justify it because of the rain, but often I am shutting them before it starts.) The fact is that lightning has been known to come inside houses via open windows. For example, in New South Wales today, lightning through open windows struck not once but twice:

The Ambulance Service of NSW said a 37-year-old man was hit by lightning while doing the washing up near a window at a YMCA camp in Yarramundi at about 7.30pm (AEDT) on Thursday.

Paramedics were treating the man, who was suffering neck and shoulder pain, and planned to take him to hospital.

Emergency services were also called to a house on Macquarie Road, in Springwood, in the NSW Blue Mountains, after it was struck by lightning at about 5pm.

"It's come through the window, it hit the curtains and ignited them," a firefighter at the scene told media at the scene.

Two people, including a man suffering smoke inhalation, were taken to Blue Mountains Hospital.

Basically, I know from first hand experience, (there are two separate stories I can tell) that otherwise intelligent people are, as a rule, still pretty much completely ignorant of, or too silly to take reasonable precautions against, the danger of lightning, even when they are in situations where the danger is absolutely as high as it could possibly be. (Well, short of doing a Benjamin Franklin and flying a kite up into it.)

But as I say, those stories are for another day.

Money and influence

How Davos makes incredibly rich people seem smarter than they actually are. - Slate Magazine

Daniel Gross notes:

It struck me that the difference between banality and profundity is generally a few billion dollars: The real alchemy of finance is to endow those skilled at finance to wield authority in adjacent or even unrelated areas. That's the general theory of Davos, bankers sharing their theories about nonbanking subjects. Stick around and you'll hear a lot of conventional wisdom on globalization, climate change, poverty reduction, financial crisis, but it somehow sounds deeper and more weighty because it's delivered by an extraordinarily wealthy CEO, a private equity executive, or hedge fund manager rather than by a journalist.

Some observations about Monckton down under

I have seen bits of Monckton on Sunrise, heard him on Alan Jones, read about his having lunch with Miranda Devine, and heard a bit of him on Radio National breakfast this morning. There are several points I want to make:

1. He is being given far too easy a ride even by those journalists who do not trust him. On Sunrise, where there was a young scientist in opposition, he was allowed to get away with the broad statement that there are many (hundreds?) of peer reviewed papers showing that climate sensitivity is low. (That is, increasing CO2 will not lead to much of an increase in temperatures.) He has continually repeated his discredited maths in his letter to Kevin Rudd. There was no real response to this alone the simple lines "the climate scientists who hold this view are in a very, very minority. There is no doubt at all that the overwhelming majority of climate scientists believe in levels of climate sensitivity which are of great concern to them and which should be acted upon now." How hard is it to say that?

People like John Quiggin argue that engaging with skeptics on science in a debate forum is often counterproductive, and I understand the point. But what is happening now is just as bad.

Sure, people who read widely on the topic know the answers to Monckton's claims already; but the average audience member who is neutral or disinterested in the topic are being done a disservice by what seems to be a non-response to Monckton's direct claims.

If scientists want the science out there, they have to get more aggressive in answering the likes of Monckton.

I haven't had time yet to watch the embedded video interview by Ben Cubby that heads the Miranda Devine article: I hope it's better, but we need more than journalists challenging him.

2. As for those who do already sympathise with him; well what do you expect. I would be interested to know, however, on what basis (according to Devine) Monckton is said to be a mathematician.

Yes I know, he came up with a puzzle that presumably shows he has an interest in mathematics. But why doesn't anyone point out that the last time he took this gamble on his expertise, he lost. (His puzzle was solved within a year, not his estimate of three.)

3. Why does anyone keep calling him "Lord", or even "Viscount" Monckton?. As David Koch noted, Monckton had invited him to call him Christopher, yet people keep insisting on referring to his completely irrelevant title. Did Jeffrey Archer keep getting this from Australian and American interviewers? Not to the same degree, as far as I can recall. I can understand why grovellers to his views like Alan Jones will use the title over and over, but those who don't believe his message, just drop it.


In short, this is no time to be taking a back step in the PR wars over AGW. Scientists need to step up to the plate in defending their work, clearly point out the errors in Monckton's claims, and the reasons he should not be believed.

UPDATE: I've now watched the Ben Cubby interview of Monckton, and it wasn't too bad. Cubby manages to get Monckton annoyed by pressing him on the meaning of "peer reviewed", and Monckton waffles on and on in his pathetically self serving way. It's like that old Keating crack about Bronwyn Bishop: he's a mile wide but an inch deep.

Something new for the home based mad scientist

The Radiation Boom - As Technology Surges, Radiation Safeguards Lag - Series - NYTimes.com

A somewhat worrying report about cases of mistakes when hospitals use new cancer treating radiation machines in the States.

According to the article, they are sold with little in the way of regulation:

In this largely unregulated marketplace, manufacturers compete by offering the latest in technology, with only a cursory review by the government, and hospitals buy the equipment to lure patients and treat them more quickly. Radiation-generating machines are so ubiquitous that used ones are even sold on eBay.

“Vendors are selling to anyone,” said Eric E. Klein, a medical physicist and professor of radiation oncology at Washington University in St. Louis. “New technologies were coming into the clinics without people thinking through from Step 1 to Step 112 to make sure everything is going to be done right.”

Surprising.
