Dr Skippy

Scientist to treat lung cancer with bacteria from roos ABC Queensland

From the report:

A Queensland scientist has won a $750,000 fellowship to develop a lung cancer treatment from a bacterium found in eastern grey kangaroos...

Dr Wei says his research involves spores of bacteria that target cancer cells.

"By injecting the spores into the blood, the spores can get into the centre of the tumour and that would work as a live active and tumour seeking agent that destroys tumours from the inside," he said.

Let's hope the side effects don't include sleeping most of the day and then a strong urge to jump in front of cars in the evening.

Janet and Michael

Jihadists owe Kirby a thank you | The Australian

Janet Albrechtsen swings out a Justice Michael Kirby in a very satisfying way in her column today.

Kirby seems to have become the new Lionel Murphy, in that he seems continually to be in the minority in High Court, at least in cases that attract a high profile. The difference is that (from memory) Murphy's judgements used to be pretty short and along the lines of "This is unjust and its about time the Court recognised the injustice in these cases, and so I find for the [insert appropriate party]."

Kirby spends a lot of time on how he explains his decisions, but they still seem to come down to exercises in justifying a gut reaction.

(Of course, some people would argue that is how all judges really work, but I am not so sure.)

His need to see everything through the prism of a gay perspective is getting very tiring with Kirby, though. His comments in court about HIV killing more people than terrorism were justly criticised by Gerard Henderson in the articles I posted about yesterday. (Oh, and I know it's not a "gay disease" for most of the world.)

Back to whales

A few posts back I referred readers to a very interesting New Yorker article about the history of American whaling.

Reading about sperm whales made me realise I had a knowledge gap: why are they called that? The New Yorker review also mentioned spermaceti as being a whaling product, and I didn't know what that was. (Ambergris I knew about: it was featured in an Uncle Scrooge comic I read as a child.)

So Wikipedia to the rescue. Spermaceti is:

... a wax present in the head cavities of the Sperm Whale (Physeter macrocephalus) and in the blubber of all whales. Spermaceti is extracted from whale oil by crystallisation at 6 °C, when treated by pressure and a chemical solution of caustic alkali. Spermaceti forms brilliant white crystals that are hard but oily to the touch, and are devoid of taste or smell, making it very useful as an ingredient in cosmetics, leatherworking and lubricants.

As for why sperm whales have it in their head, this is rather interesting:

One function of the spermaceti organs is a buoyancy or diving organ. Before diving, cold water is brought through the organ and the wax is solidified . The increase in specific density generates a down force (approx 40 kg equiv) and allows the whale effortless sinking. During the chase in deep levels (max 3km!) the stored oxygen is consumed and excess heat melts the spermaceti. Now only hydrodynamic forces (by swimming) keep the whale down before effortlessly surfacing.

Knowledge gap filled.

A good idea

Remedy for mistrust | The Australian

This article makes a case for having a national system of assessment for foreign doctors. Sounds sensible, doesn't it?

My polling commentary

Newspoll shows the coalition still stuck in the polls, but at least I take some consolation from the fact that a significant majority agree with the Haneef visa revocation, despite all the heat generated by left-y bloggers and the odd editorial campaign of The Australian against Andrews personally. Howard still leads in the "who would handle security better" question too.

As for the 10 point TPP lead to Labor at this stage: well it will just make the ultimate Coalition election victory all that more lauded!

Some reasons why I am not giving up on the Coalition yet:

* You would need to see polling on a State by State basis to see how many seats are in danger. Western Australian is still mentioned as not good for Labor, and there is fierce opposition to Beattie's out-of-the-blue council amalgamation plan in Queensland. It seems that the actual amalgamation process will be still underway during the Federal election, and it is bound to cause some vote changing in some rural seats at least. Maybe not much, but some. Meanwhile, the hospital decision in Tasmania might have worked for Howard in that one seat. (It's going to take a lot to win the election one seat at a time, though!)

* Is it possible for Rudd to be a smaller target than he has been in the last few weeks? If people like him for being "Howard lite," is there a chance they will actually switch allegiance back to Howard when it comes to a crunch? And I don't expect that people currently siding with Rudd in polls are thinking of Labor as a team at the moment. Wayne Swan does not seem to me to be performing well in interviews this year; I reckon there is danger that Peter Garrett is going to self-implode due to some guilt over having to sell his idealism to be part of the party; and I still think that Julia Gillard is not entirely loveable despite the various make overs and appearances on women's magazines indicate.

* There was some mention somewhere in the last couple of weeks that Tony Abbot's comment that the "darker aspects" of Rudd's political career may come to light was a reference to some journalistic digging that he knows about. It would have to be very dirty indeed, though, not to backfire. Still, if Rudd displays a glass jaw again, it may have an effect.

* John Howard seems certainly to have been right in his prediction earlier this year that he did not expect the polling to change significantly until the election is called. Still, that's little comfort to his supporters when even the betting is starting to go strongly against you.

The body electric

ScienceDaily: Electric Fields Have Potential As A Cancer Treatment

An interesting report on hopeful indications of low level electric fields to the head helping treat some forms of brain cancer.

The idea that electric fields could be helpful therapy has been around a long time (ever since electricity was understood, I guess.) It also gets a mention in science fiction every now and then, if I recall correctly. So its good to see there may be something in it after all.

Improbable research

Speaking out | eG weekly | EducationGuardian.co.uk

From the article:

In the 1990s, daring researchers finally tackled a question that was discussed everywhere except in formal academic settings. When someone's speech "sounds gay", what makes it sound that way?

Not exactly crucial to the advancement of the human condition, but it's good to see that I am not the only person to have wondered why (some) gay men sound so gay.

Sex and children

I’m single, I’m sexy, and I’m only 13 - Times Online

This article from The Times is a week old, but worth reading.

It's all about the ridiculously early sexualisation of young girls, especially young teenage girls.

It does cite some odd research, though, such as this:

The APA report also featured a 1998 study, in which the same researchers asked college-aged girls to try on either a swimsuit or a sweater, assess their appearance, then perform mathematical tests. The girls asked to wear swimsuits performed significantly worse.

“This is how sexualisation fragments consciousness,” says Dr Lamb. “These girls were so hung up on their appearance they literally didn’t have room in their heads to do maths. They learn that preoccupation from the women they look up to in the media.”

One psychologist explains the problem this way:

Though Dr Wilson believes flirtation and exhibitionism are natural for young girls, he says that clear lines must be drawn. “Children want to be looked at, but wearing items like thongs and revealing clothes sends the message that they are sexually available. It also implies knowledge of sexuality that just isn’t there,” he says.

As to the group think of girls, it also points out this:

But while criticism of the media is the answer Dr Lamb hopes for, it is girls criticising each other that is beginning to change attitudes among some groups. “There is a backlash beginning,” she says. “Girls quickly go from being popular to being derided for their slutty behaviour. It’s sad because they do all these things to fit in, but go too far and they are soon turned against.”

I wonder if anyone has looked at the comparative "early sexualisation" behaviour of girls from mixed gender schools and girls only ones.

Drive more and save the planet

Walking to the shops ‘damages planet more than going by car’ - Times Online

This is possibly the funniest thing Tim Blair would ever have read about greenhouse gases (with considerable justification , I might add), and he's missing out on blogging about it 'cos he's off on holiday somewhere.

Short version: raising cows makes so many greenhouse gases, you are better off driving the car to the supermarket than walking and having to replace those calories with extra intake of beef or milk.

But there's more:

Mr Goodall, Green Party parliamentary candidate for Oxford West & Abingdon, is the latest serious thinker to turn popular myths about the environment on their head.

Catching a diesel train is now twice as polluting as travelling by car for an average family, the Rail Safety and Standards Board admitted recently. Paper bags are worse for the environment than plastic because of the extra energy needed to manufacture and transport them, the Government says.

Makes me feel so much better.

As for flying, there seems to have been a bit of a backlash against the "the world must fly less" views of George Monbiot and others, and a good article in The Observer a couple of weeks ago talked about the difficulties of comparisons between different modes of transport.

And now for something completely different

Found by accident, here's some very innovative looking stage magic with (what looks like) laser light.



Very, very cool!

Things you never knew about whaling

This is one of those New Yorker book reviews of very pleasing length, where you end up up feeling that you have learnt a lot of things you didn't know before, with the added benefit that it seems hardly necessary to buy the book now.

The book in question "Leviathan", is a history of American whaling.

One thing it has taught me is that there was a fair bit left out of the movie version of Moby Dick:

Nor is there anything like skinning the whale’s penis, “longer than a Kentuckian is tall,” and wearing it as a tunic while you slice up the fat harvested from the rest of its body. Melville’s narrator, Ishmael, claims that the mincer of blubber usually wore such a tunic, in a clerical cut that made him look like “a candidate for an archbishoprick.” For “Moby-Dick,” Melville drew on scientific, historical, and journalistic accounts of whales, but he had a reputation for blurring the line between fact and fiction, and scholars have noted that for this chapter “none of Melville’s fish documents was particularly helpful.” In other words, he may have made the tunic up, for the sake of the archiepiscopal pun and perhaps, too, as a symbol.

It's a really interesting read. Go to it.

Revenge of the dolphins

Taiji officials: Dolphin meat 'toxic waste' | The Japan Times Online

Letting nothing get between them and a school of fish, the Japanese residents of Taiji kill hundreds of dolphins each year in a particularly gruesome fashion. Foreign Correspondent had a story about it in 2005. It was noted there that some of the dolphin meat is eaten locally.

The Japan Times story at the top says that this is a bad idea, because testing indicates it contains a very high level of mercury. All very unfortunate for the local school kids too, who have had dolphin meat put in the school supplied lunches.

The Japanese Fisheries bureaucracy remains hard to convince. God forbid that anything, even human health, should stop them killing and munching on whatever sea creature they like:

Tetsuya Endo, a professor and researcher at Hokkaido Health Science University's faculty of pharmaceutical sciences, affirmed the other doctors' condemnation of small-cetacean food products.

In a terse e-mail sent to this correspondent, Endo said, in reference to dolphin meat, "It's not food!"

In 2005, Endo published the results of a three-year study on random samples of cetacean food products sold throughout Japan, and concluded all of it was unhealthy because of high levels of mercury and methylmercury.

However, Hideki Moronuki, deputy director of the government's Far Seas Fisheries Division of the Resources Management Department, in an interview with The Japan Times, maligned Endo's study, calling it "misleading information." When pressed, though, he failed to substantiate his accusation.

The Japanese obsession with fish is a problem. As another Foreign Correspondent report (this one on massive Japanese overfishing of tuna off Australia and elsewhere) noted:

Japan has only two per cent of the world’s population yet Japanese eat a chunky ten per cent of the global fish catch. The national appetite seems almost insatiable.

Looking at Iran

Is Iran paranoid or does it really have something to hide? | Guardian Unlimited

This is a fascinating report on a recent attempt at PR by the Iranians for its nuclear industry.

It really sounds like a crazy government:

Petrol costs about 10p a litre, so Tehran is usually one continuous traffic jam. On Friday there is gridlock at midnight. And electricity is 70% subsidised. Seen from the air at nights, the capital burns as bright as any American metropolis. Because petrol is sold so cheaply, it makes no economic sense to build refineries in Iran, but because of the absence of refineries there is actually a petrol shortage. Rather than raise prices, the government has introduced rationing, handing out smart cards that limit most users to 100 litres a month. There was an initial wave of protests a month ago when the scheme was first introduced but those have since faded. The lull may be an illusion though. Many people have burned through much of the four-month ration on their initial smart card in just over 30 days. When the cards run out and people can no longer get to work, there is likely to be another bout of anger and frustration.

Geo engineering risks

'Sunshade' for global warming could cause drought

Read the linked story for some scepticism of one of the more plausible geo-engineering ideas against global warming (using sulphur particles high in the atmosphere).

Necks and blood pressure

How a pain in the neck could be bad for your blood pressure

This is an interesting little story about the possible connections (at least for some people) between the neck and high blood pressure.

I recall reading years ago in a Discover magazine (perhaps as far back as the 1980's) about some cases where experimental surgery on (I think) a nerve on the neck seemed to cure some cases of high blood pressure. I thought it interesting at the time, because of a relative of mine who has had high blood pressure from a relatively young age, yet has always led a healthy, active life style.

After that, I don't recall seeing anything about necks and blood pressure anywhere. Of course, it is not something I go out of my way to look for.

Homer's brain on display

Doh!

Very amusing to see that Homer Simpson's brain somehow made it onto a serious Chinese media report.

No one believes the Courier Mail?

Haneef caught in Groundhog Day, says lawyer | The Courier-Mail

Yesterday, the Courier Mail reported on what may have been in the undisclosed evidence that Minister Andrews has referred to in his Dr Haneef visa revocation decision.

It's pretty major stuff: that Haneef had come to the attention of MI5 because he was in contact with radicals they were monitoring. The Courier Mail repeats it briefly today (see link above).

I heard this mentioned on Radio National Breakfast yesterday, not in the "news" but in the "what's in the papers today" section.

Yet, that is absolutely the only reference to the story I have heard anywhere else. Instead, the dodgy , just created Indian "dossier" got all the attention, and even Keelty seems to dismiss that as not very important.

Why would this story be being ignored? Does no other journalist in Australia trust the Courier Mail? Why has no one mentioned it to Keelty?

I find this very puzzling....

UPDATE: a Google news search confirms that this story is getting virtually zero attention. It seems to me that there has to be a reason for this.

More questionable than I expected

Angry Toxicologist : Fluoride - it's not just for teeth anymore!

The anti-fluoridation crowd usually sound a little too much like cranks to me to pay them too much attention. Surely I can trust all those dentists who want the water fluoridated, can't I?

Brisbane's water supply is still not fluoridated, (I think), and the post above at a Seed science blog makes me think those against it may have more going for them than I expected.
