What next? Tin foil hats work too?

The results are preliminary, but appear in the Journal of Neurology, Neurosurgery and Psychiatry (sounds legit):

Applying magnets to the brains of Alzheimer's disease sufferers helps them understand what is said to them. The finding by Italian scientsts, who conducted a randomised controlled trial of the treatment, suggests that magnets may alter "cortical activity" in the brain, readjusting unhealthy patterns caused by disease or damage. The study was small, involving just 10 patients, and the results are preliminary.

Surprising, but it's not as if it was just a matter of putting magnets in a headband:

For the latest study, Maria Costelli and colleagues applied repetitive TMS – a rapid succession of magnetic pulses – to the prefrontal lobes of the Alzheimer's patients for 25 minutes at a time. Half the patients received daily doses five days a week for four weeks and half received a dummy treatment for two weeks followed by two weeks of TMS. Tests showed that those who had the full course of TMS had significantly higher scores on comprehension of what was said to them – up from 66 per cent to 77 per cent. The improvement was still evident eight weeks after treatment. The authors say the technique did not affect other language abilities or other cognitive functions, including memory, which suggests that it is "specific to the language domain of the brain when applied to the prefrontal lobes".

Half my wish fulfilled

Recently, I indicated that my depression over what looked like the coming appalling electoral choice between Kevin Rudd and Tony Abbott would be resolved if Labor installed Gillard as Leader, and the Liberals went back toTurnbull.

Well, looks like half of my wish has come true.

Basically, Rudd suddenly imploded because he is a two-faced, control freak, vain, celebrity-seeking, boss-from-hell, media tart of a politician who was only installed as leader as a result of his smiley Sunrise appearances which gave Labor the feeling that he was just the right person to not scare the voters from blasting Howard out of the chair which he had unwisely decided to keep for one election too many. There always existed plenty of evidence for all of this; it is amazing that it took the public as long as it did to turn on him (and even now, that it has not turned as completely as it could,) but it is not really that surprising that Labor turned on him at the first possible opportunity.

Now, how am I to hope for Abbott to lose his position? The only way I see is for him to (literally) be caught with his pants down somewhere with someone other than his wife.* It's possible; I should never give up hope!

* Now that I think about it, I speculated once or twice on this blog during Rudd's puzzling rise to power that this was how he might come to grief too, but it was only with his ETS backflip that we all realised he had no testicles anyway. Maybe I'm just longing for another scandal as good as the Gareth Evans/ Cheryl Kernot one.

Odd headline of the day

How Time and Life magazines helped turn America on to LSD. - By Jack Shafer - Slate Magazine

Well, that's interesting! I didn't know that the Time and Life magazine co-founder and his wife (Henry and Clare Luce) were right into LSD, and this explains why those conservative magazines gave oddly sympathetic coverage of the drug in the late 50's and into the 1960's.

One pleasing strange aspect of this:

Clare's acid trips, which she recorded in her papers now at the Library of Congress, were of the garden variety. She sorts mosaic glass by her swimming pool. She entertains herself looking through a kaleidoscope. During a March 11, 1959, trip, Richard Nixon telephoned Clare at her Phoenix home. An active Republican who served in Congress and as an ambassador, Clare declined to speak to Nixon. How history might have changed if she had shared a little acid with him!

It could have been a stranger conversation than the one Nixon had with Elvis.

It’s ours, all ours

In what would probably be a rare bit of good news for Australian professional astronomers:

MORE than 35 years after Prince Charles opened Australia's biggest optical telescope - a joint venture between our two nations to explore the southern skies - we are bidding goodbye to the Brits.

From next month, the Anglo-Australian Observatory near the NSW town of Coonabarabran will become the Australian Astronomical Observatory.

Its director, Matthew Colless, said the decades of collaboration with Britain had led to many big discoveries about the universe, including a measurement of the matter it contains.

But 100 per cent ownership of the observatory's four-metre telescope, which is still ranked highly in the world, would open up new opportunities for research in the coming decade.

I’ve been there once in the late 1980’s, and I recall it as having a pretty good visitor centre. Somewhere in a drawer I probably have a photo, but here’s one from the web.

Cheap real estate in Japan

We all saw on TV last year how you could buy abandoned houses in many parts of the US for a song. Unfortunately, it looked like many had been thoroughly vandalised, and were in neighbourhoods which might take a decade or so to feel safe and inhabited again. A house for a couple of thousand dollars in such a situation is not such a bargain.

But Japan is a different kettle of fish. (That’s a particularly apt expression for that country, come to think of it.)

Population decline has already set in, and about the only places growing are the big cities due to people leaving the rural areas. I had been wondering if bargains in housing were to be had, and this fascinating article claims that there are:

So just how many vacant properties are there in Japan? According to the Internal Affairs and Communications Ministry in 2008, there were an amazing 4.127 million unoccupied housing units, up 451,900 from 2003.

Some of these are old decaying abandoned homes which you wouldn’t want anyway, but it is still a big number, and it’s only likely to get bigger. The article goes on to provide a website which lists properties for sale as a result of tax foreclosures, but unfortunately it is in Japanese only, and is not exactly what you would call a glossy looking real estate site.

There is one major cultural difference about Japan which is odd to Westerners: except for apartments, modern Japanese do not expect houses to last long:

One reason why foreigners are a good fit to solve the vacant housing problem is that they are more willing to live in older properties and to perform their own maintenance. Japanese have been educated over the last 50 years that housing older than 25 years old should be demolished and rebuilt, leading people to really only want to buy new places. I know this firsthand, after a relative bought a countryside property, built a substantial Japanese-style post-and-beam house on the land (and which will last another 50 to 100 years), but being told by the bank several years ago that the house itself is now considered to already have zero value!

Some suggest that the Japanese expectation for the life of a house is affected by the number of earthquakes it might be expected to endure. But I am sure it is more than that. I was recently speaking to a Japanese couple, now Australian residents, who explained how surprised they were to find that renovated older homes (particularly in the Queenslander style) in Brisbane were expensive and highly valued. I think there is an idea that houses carry any bad luck that happened in them into the future.

Lots of websites say that there is no equivalent to our Foreign Investment Review Board restrictions on foreign purchase of real estate in Japan. (They also say that dealing with real estate agents may not be easy, but the article I linked to says there is a move afoot to encourage real estate agents to be helpful to foreign investors.)

All of this certainly suggests that you don’t buy a house in Japan with an expectation of making capital gain. But the idea of having a holiday home in the very pretty countryside of Japan might be a quite viable option for foreigners in the future.

Cheap books, electronic and otherwise

E-reader prices have taken a tumble in America due to the success of the iPad.

Recently I saw at Dymocks the Kobo e-reader for $199, but they have sold out and you have to place them on order.   I thought the screen was a bit small though, but then I thought the same when I saw a Kindle.

Anyhow, I’ll still wait for the next generation of them before buying.  I’m currently getting plenty of cheap reading by going to the Lifeline Bookfest held every 6 months in Brisbane’s convention centre. 

In January, as I have reported here before, I got Clive James’ first volume of autobiography which I had been wanting to read for years.   This time (on the Queens Birthday weekend) I got the second volume.  I am also getting more Graham Greene, including his autobiography, and he is difficult to find anywhere other than second hand book stores.

One thing you do learn from going to the Lifeline book sale is this:  there are a hell of a lot of Bryce Courtney novels sold in Australia.  Unfortunately, he has no appeal to me at all.

For readers outside of Brisbane who may not understand the size of this Lifeline second hand book sale, here’s a photo from the Brisbane Times which gives a good indication:

We like out second hand books in Brisbane.

Lucky planet

Summer solstice: Did a rampaging planet create Earth's seasons? - CSMonitor.com

Of course I knew of the idea that it was a collision that formed the Moon, but I either didn't know (or had forgotten) that it may also have given us the Earth's very convenient axis tilt that gives us the seasons:

Without that tilt, we might've ended up with more seasons than we could deal with over the course of Earth's history, suggests Neil Comins, an astronomer at the University of Maine. He's written substantially on what alternate Earths might be like and how hospitable they would be for the emergence of life.

The collision thought to have generated the tilt also created the moon, which is responsible for stabilizing Earth's spin axis. Without a moon, "the Earth spinning on its axis is an unstable system in which the tilt goes from straight up and down to far closer to the plain of it orbit than the axis is today," he says.

At its most extreme, this could leave Earth orbiting the sun and spinning on its axis like a chicken roasting on a spit with head and tail alternately aimed at the fire, rather than cooking the bird broadside. Earthlings from one pole to the equator would be in darkness during the solstice, while the other half would be in toasty sunlight. The poles would swap lighting conditions at the next solstice.

Moreover, the moon's presence and its effect on the oceans act as a brake on Earth's rotation rate. By some estimates one turn of the Earth on its axis some 4.5 billion years ago would have taken 6.5 hours, versus 24 today. No moon means a far more speedy cosmic rotisserie.

I don't think the importance of the moon in keeping the axis tilt stable was something that I realised before. Very neat.

Impressive

BBC News - Tornado rips roof off sports arena in Montana

Some pretty impressive video here of tornado damage. Two things of note: the amount of rubbish a tornado can keep suspended in the air for a long time, and the cars and trucks that seem to be passing by quite close to it. (I would be speeding away as fast as possible, but these vehicles don't seem to be in that much of a hurry.)

Expensive brides

I commented a while ago that a documentary about a large restaurant in China seemed to show many Chinese women as being intensely materialistic, and a story about real estate in China seems to back this up:

Unlike in the United States, where home buying traditionally takes place after marriage, owning a place in China has recently become a prerequisite for tying the knot. Experts said securing an apartment in this market signals that a man is successful, family-oriented and able to weather challenging financial circumstances. Put succinctly, homeownership has become the ultimate symbol of virility in today's China.

"A man is not a man if he doesn't own a house," said Chen Xiaomin, director of the Women's Studies Center at the Shanghai University of Political Science and Law. "Marriage is becoming more and more materialistic. This is a huge change in Chinese society. No matter how confident a woman is, she will lose face if her boyfriend or husband doesn't have a house."

Dating websites are now awash with women stipulating that hopefuls must come with a residence (and often a set of wheels) in tow.

Medical technology's downside

A Pacemaker Wrecks a Family's Life - NYTimes.com

This is a long but quite interesting story about how the use of pacemakers in the elderly in the US appears to be prolonging lives that do not want to be prolonged. It has apparently proved difficult to get permission to turn the things off.

It appears that only very recently has the American Heart Association issued guidelines that patients or their "legal surrogates" (people with Enduring Power of Attorney in Australia's case) could request the withdrawal of medical treatment, including implanted pacemakers, and that this would not be euthanasia or assisted suicide.

I wonder if there has been any similar uncertainty in Australia, or if this was largely a product of American concern over litigation. Tell us, Geoff.

That's hot

AFP: Kuwaiti MPs call for shorter work hours to save power

From the report:

Last week, the oil-rich OPEC member almost resorted to power cuts after a sharp rise in demand in response to record temperatures that soared to 52 degrees Celsius (125.6 Fahrenheit), the highest in more than 30 years.

Surely a dry heat of 52 degrees is not exactly healthy without airconditioning, so I am curious as to what happens to death rates when the power is cut off during a day like that. (Then again, I suppose people have been living in the desert for a long time. Why on earth did they stay there?)

Interesting terms found on the Web today

1. Cat therapist. (From New York; not California as you might have expected.)

2. Sexually Satisfying Events. It's a medical term used in trials of libido enhancing drugs, apparently. I wonder if there’s a requirement that two people be involved?

Once a certain age is reached, perhaps a more relevant term is needed, such as "Sexually Satisfying Event Equivalent." (I expect most of mine to involve cheese.)

3. The Theory of Exclusively Local Beables. This is from arXiv, which is a bit of an obvious source for novel phrases: every second paper has a title with a term I haven’t heard of before. Anyhow, “beables” is a charming sounding word, and is described as follows:

J.S. Bell introduced the term “beables” (a deliberate contrast to the vaguely-defined “observables” which, he thought, played too prominent a role in orthodox, Copenhagen quantum theory) to name whatever is posited, by a candidate theory, as corresponding directly to something that is physically real (independent of any “observation”).

The paper talks of “pilot wave” theories to explain the quantum world, and is of some interest, especially in its introductory explanation of how such theories to explain the dual particle/wave characteristics of light were considered from the beginning by Einstein, but they lost out to the “tranquilizing philosophy” of Bohr’s Copenhagen interpretation. (The paper goes on to suggest that there is merit still in the pilot wave idea.)

4. Everyone has two puberties. Recently I link to a list of very dubious ideas Kant had about life, yet today while reading a bit of a rambling article in The Guardian about marriage, I found this:

I think Elizabeth Gilbert gets somewhere close to it when she quotes Kant in his assertion that we humans are so emotionally complex that we go through two puberties in life: the first when our bodies are mature enough for sex, and the second when our minds are.

Sounds about right; good on you Immanuel. (But having reputedly died a virgin, I wonder how he assessed his own preparedness for it.) *

* At another blog earlier this year, I imagined a movie involving Kant (who, apart from alleged sexual inexperience, also never travelled more than 100 miles from his home town of Konigsberg) as actually being a secret prototype James Bond character, involved in political intrigue and bedding femme fatales all over Europe and the Americas in the 1770's. (Wikipedia says he had a "silent decade" in his 40's.) I await the grant for the script from the Australian Film Commission: God knows they haven't funded enough films involving improbable historical fantasies based in Prussia.

Big brother death throes

Charlie Brooker writes pretty amusingly on the final series of the British version of Big Brother. (Yes, it is a sure sign of the cultural sickness at the heart of that country that its BB outlived, and seemed to attract more attention, than its Australian counterpart.)

It’s small, but my favourite line in the article is towards the end:

Throughout the first series, broadcast in 1912, the contestants occasionally sang "it's only a game show!" to keep their spirits up.

The Japanese way

This was reported last weekend, apparently, but I missed it:

Britain’s Sunday Times reported in its online edition that Japan had bribed small nations with cash and prostitutes to gain their support for the mass slaughter of whales.

The International Whaling Commission (IWC) commissioner for Tanzania said “call girls” were made available at the hotels for ministers and senior fisheries civil servants during all-expenses paid trips to Japan, the paper reported.

The Sunday Times’ investigation revealed that officials from six countries were willing to consider selling their votes on the IWC. According to the report, the governments of St Kitts and Nevis, the Marshall Islands, Kiribati, Grenada, Republic of Guinea and Ivory Coast negotiated selling their votes in return for aid. One official said that call girls were offered when fisheries ministers and civil servants visited Japan for meetings.

A top fisheries official for Guinea said Japan usually gave his minister a “minimum” of $1,000 a day spending money in cash during IWC and other fisheries meetings, the paper reported.

More floods = climate change?

String of floods raise climate change questions - Capital Weather Gang

I think this is a pretty balanced article about what the media can appropriately say about recent floods in the States and climate change.

Meanwhile, the UK Met Office says that even if CO2 dropped after its rise, rainfall changes caused by AGW would hang around for decades. Seems pretty academic to me: why bother looking at unrealistic theoretical drops in CO2? Anyway, their modelling for what rainfall changes AGW will cause indicates:

High latitude countries such as Canada and Russia would receive more rain and snow, whereas other regions such as the Amazon basin, Australia and parts of sub-Saharan Africa would receive substantially less.

As the oceans have huge capacity to store heat, releasing the heat relating to a temporary quadrupling of the man-made greenhouse effect would take many decades.

The Met Office computer model is known to project more drying of the Amazon than most others.

Last night's Catalyst had an interesting story on Western Australia being unusually dry for the last 30 years. They don't say it's all CO2's fault; changes to the ozone layer get much blame too.

All a bit of a worry.

I can't resist a Bigfoot story, but there's nothing much to this one. Still, it's an excuse to refer people to the Messin' with Sasquatch beef jerky ads from America, which have been around for some years, but I only found them recently. Here's the first, which sets the tone for the rest:



I suppose it's not dissimilar to the Betty White ad I featured recently: I find unexpected violence pretty funny. Sorry.

Making babies: highly questionable research

Is there any greater sign of the modern over-enlarged sense of entitlement than the ART ("assisted reproduction technology") business? [Yes, I know, I was lucky enough not to have go looking into that to have kids of my own, but high abortion rates means that it's not for a lack of embryos in the West that there is a shortage of babies born. Indeed, despite the problems inherent in international adoption, I would still prefer to see more of that than kids left in the pathetic orphanages that exist in some countries.]

There have been quite a few stories of interest about ART this lately, and some really bad reporting. This will be a long post.

First: Let's oversell "Two Mums is good". It was widely reported, as in this example from the Sydney Morning Herald short report, with the jolly title "Two Mums Better than Dad":

"..researchers found children born to and raised by lesbian couples were better off socially, academically and more competent than their peers."

All complete with happy photo of (impliedly) happy lesbian family, although as they are not identified, for all I know they could be a couple of Fairfax reporters who posed with the bosses' toddler.

Anyhow, the study was based on following 154 pregnant (from artificial insemination) lesbian women from the 1980's and comparing them to heterosexual families. Beginning to suspect this study might have some flaws? Your suspicions would be right. As economist blogger David Friedman notes, one obvious way it might be unreliable would be if the two groups of parents were not closely matched for other factors that may very well be relevant to having a "better off" child:

The two groups might differ in important ways other than their sexual preferences. Most obviously, since the lesbian parents had conceived via artificial insemination, their pregnancies were all planned and all desired. If the comparison group contained a significant number of children from unplanned and unwanted pregnancies, that might explain why more of them had behavioral problems. One could imagine a variety of other possible explanations as well—and the news stories did not provide enough information to confirm or reject them.

He then reads the paper and reports:

The two groups were not closely matched, due to data limitations, a problem that the authors noted. They differed strikingly in geographic location, since the lesbian couples were all recruited in the Boston, D.C., and San Francisco meteropolitan areas, while the data on children of heterosexual couples, coming from another researcher's work, was based on a wider distribution of locations. They were not matched racially—14% of the heterosexual couples were black, 3% of the lesbian couples were. They were not matched socio-economically—on average, the heterosexual couples were of higher SES than the lesbian couples.

As someone commented in the Sydney Morning Herald guessed:

This study may be more about the socio-economic than about gender! In that regard it simply confirms what we already know: advantaged parents are able to raise advantaged children. It is not that "2 mums better than dad". Rather, it is that "2 advantaged parents are better than 2 less advantaged ones".

David Friedman then finds another startling problem with the research:

Questionaires went, at various points in the study, to both mothers and children. But the conclusion about how well adjusted the children were was based entirely on the reports of ther mothers. A more accurate, if less punchy, headline would have read: "Lesbian Mothers Think Better of Their Kids than Heterosexual Mothers Do."

Friedman is not out to criticise the authors, as the inadequacies are there to see in the paper. It certainly seems to me, though, that the authors are not above overselling their report to the media, such as when they are quoted as follows:

"Our findings show that adolescents who have been raised since birth in planned lesbian families demonstrate healthy psychological adjustment and thus provide no justification for restricting access to reproductive technologies or child custody on the basis of the sexual orientation of the parents."

Hmm. Does that sound just a tad like they have the view that they have a message to sell? Their funding did come from lesbian friendly foundations. What a surprise.

I don't think many people expect lesbian couples to be atrocious at parenting; at the same time, this is a bit of peer reviewed research that proves nothing and is being oversold by its authors.

Second: Let's not report a survey that indicates some kids are not so happy about not knowing their Dad:

OK, OK, this is not a peer reviewed bit of research and it comes out of a conservative foundation and was partly conducted by a person with a personal interest in the issue. But it got a run in Slate, which was kind of brave of them, as it would clearly upset many liberals because, you know, everyone is entitled to get knocked up via an anonymous sperm donor and who are we to question whether that's a wise thing to do?

The report is a survey which compared attitudes between 3 groups: "18- to 45-year-olds includes 485 who were conceived via sperm donation, 562 adopted as infants, and 563 raised by their biological parents." Some of the findings:

Regardless of socioeconomic status, donor offspring are twice as likely as those raised by biological parents to report problems with the law before age 25. They are more than twice as likely to report having struggled with substance abuse. And they are about 1.5 times as likely to report depression or other mental health problems.

As a group, the donor offspring in our study are suffering more than those who were adopted: hurting more, feeling more confused, and feeling more isolated from their families. (And our study found that the adoptees on average are struggling more than those raised by their biological parents.) The donor offspring are more likely than the adopted to have struggled with addiction and delinquency and, similar to the adopted, a significant number have confronted depression or other mental illness. Nearly half of donor offspring, and more than half of adoptees, agree, "It is better to adopt than to use donated sperm or eggs to have a child."

Of course, there may well be biases in the selection of the subjects here (although I haven't read anyone pointing out precisely how yet), and it's not "peer reviewed", but is it all that surprising that some adults from anonymous sperm donation would worry about things like whether someone they meet might actually be their half sibling? This is particularly so in America, which for some reason is still allowing anonymous donors to remain anonymous all their life. (This has been changed in Australia and much of Europe, with the result that very few men are now willing to be sperm donors. In Australia, the donor can't even be paid!)

Everyone knows that adopted kids, as adults, often feel that the fact of their adoption is an important issue about their life, hence all the shows and stories about the desire to re-unite with their biological parents. It makes many of them feel more complete.

So it should be no surprise at all that many sperm donor kids should feel the same way.

I reckon there is likely to be more truth and accuracy in this study than the lesbian parent one.

Of course, if you are going to allow companies to provide this service, the anonymity should be illegal. It is cruel to deliberately create a kid with this uncertainty in its future.

Yet, of course, it wasn't mentioned in the media much at all.

Third: just how many defects does ART create in babies?

There was some reporting of a new study that at first sounds like it should be a big worry for those considering IVF:

Slightly more than 4% of babies born via assisted reproductive technology such as in vitro fertilization (IVF) may have major birth defects, such as heart and urogenital tract malformations, according to a new study...

The major birth defects seen in babies born via IVF and/or ICSI included heart defects and malformations of the urogenital tract, such as hypospadias (an abnormality in the position of the opening of the urethra in boys). In the study, 110 children had genetic disorders, including six children with Beckwith-Weidemann syndrome, which is marked by body overgrowth, and may increase risk of certain cancers. Five children also had bilateral retinoblastoma (cancer of the eye's retina).

Children born via assisted reproductive technology had a five times higher rate for minor birth defects such as angiomas (a benign tumor of small blood vessels causing a red growth on the skin). Angiomas were twice as common in girls as in boys, the study found.

But:

U.S. experts are quick to point out that these risks are not much different from what would be expected in the general population. And the risks are much lower than what has been found in some other studies of babies born as a result of fertility treatments.

This research came from surveys in France, and the lead authors Geralidine Viot (see above link) is quoted as saying:

"our results are not so different from the general population and I consider them rather reassuring as some previously reported studies showed increased risk of major malformations around 9% to 11%," she says.

Wait a minute: why is so much discrepancy between the rate of defects in these studies? Just how hard is it to record defects from babies from IVF?

And what's going on here: in the report of this study from The Independent, we read:

The study, the largest of its kind, found evidence of a higher-than-expected rate of serious congenital abnormalities.

Research leader Geraldine Viot said: "We found a major congenital malformation in 4.24pc of the children, compared with the 2-3pc that we had expected from previous published studies.

"This higher rate was due in part to an excess of heart diseases and malformations of the uro-genital system. This was much more common in boys.

Those comments regarding what they expected from previous studies doesn't seem to match the earlier quote, where she was relieved that their rate was half that of previous studies.

There's some explaining that needs to be done about all this. There are studies from Australia indicating defect rates "twice" that of naturally conceived children, and an American report from 2 years ago that found:

The CDC reports that certain birth defects -- including heart wall problems and cleft lip/palate -- may be two to four times more common among babies conceived with assisted reproductive technology (ART) than babies conceived naturally.

They are also keen to note:

The study doesn't prove that ART was to blame for the birth defects.

"Subfertile women might have a higher risk of having a child with a birth defect regardless of whether infertility treatments are used," write Reefhuis and colleagues.

So it may not be the ART process itself that "causes" it, instead it may be the decision to use ART to get a baby with a higher risk of a major defect when your natural infertility would have prevented it. Well, I hope that IVF clinics make this subtle "it's not us, it's you" distinction known to their clients.

In fact, it seems to me ART doctors are dead keen to downplay the significance of increased rates of defects. For example, this is from the Melbourne Herald Sun report on the recent French study:

Dr John McBain, Melbourne IVF director and head of reproductive services at the Royal Women's Hospital, said the definition of "major" congenital abnormalities was contentious, and included conditions such as clicky hips and club feet.

He said it was difficult to compare the health of children conceived naturally and through ART.

"The children born from assisted conception have more rigorous physical examinations," he said.

This is self interested excuse making, if you ask me.

And funnily enough, when you go to the glossy IVF Australia website and search it for terms such as "birth defects", "congenital defects" or "birth abnormalities", you score nothing that talks about increased rates of these for IVF babies. (That's not to say that they don't give appropriate information to those who contact them, but I would be curious as to how they explain the risks, given the apparent conflict between results of studies over the last decade.)

I remain very cynical about virtually all aspects of "Assisted Reproductive Technologies", but it's a good little earner I'm sure.
