Limited responsibility

Well that's good. Due to a change in my electorate's boundaries, I am now living in what appears to be one of the safest Labor seats in Brisbane. Previously, I was in a seat that swung from side to side, and my vote actually mattered. Given the appalling choices this election, I kind of like the sensation of irrelevancy, at least for the moment.

The Senate remains a problem. The Greens have exactly one policy I support, but it's an important one - a carbon tax.

Both Labor and Liberal say there will be no carbon tax. Brown thinks he can force one through, and he supports a mining tax, but wants to increase the amount that can be gained from it. I generally support the mining profits tax, but don't really trust Brown's fiddle with it.

The Coalition really can't be trusted on environmental issues while there are under the sway of Abbott and his supporters.

The likely line up of independents seems very up in the air, except I think everyone expects the slightly loopy Fielding to go. I don't know anything about independents running in Queensland.

I think it is looking like, in the mix, I would probably be best off supporting Labor in the Senate, while at the same time hoping Brown wins eventually on the carbon tax.

UPDATE: courtesy of Antony Green's election site, I now have a good idea of what's going on in the Senate at Queensland level. Hey, Barnaby Joyce is up for re-election. As well as George Brandis.

Joe Ludwig is also on the card for Labor.

The game of who to put last is always a challenge. This time, it looks like a contest between both of them in the Climate Sceptics Party and the perpetual protester Sam Watson of the Socialist Alliance.

What do you know: the Australian Democrats still exist! I expect they hold their conferences in one of the meeting rooms at the local Council library.

Well, this is going to take some studying.

Rat dad research

The Brains of Our Fathers: Does Parenting Rewire Dads?: Scientific American

Just in time for Father's Day, here's talk about some research into rat fathers which might indicate why human fathers are important too:

While it appears the seed of the father-child bond is planted by supplemental neurons in a new dad, it seems a child, on the other hand, may be born with a brain that expects this bond to form in the first place.

To prove this, a few recent studies turned to a rodent that employs a remarkably familiar nest structure. Degu rats are biparental animals, which means parenting duties are split between the mothers and father. Degu fathers behave just like human fathers. They spend the early days of their pups’ lives helping with basic care, like warming and grooming. And as the pups get older, the degu fathers begin actively playing with their toddler offspring.

Researchers reasoned that absent fathers in the degu nests would create a true social and emotional void for the offspring, just as a missing dad would impact the dynamic of a human family. They found that if a rodent father remained in the nest with his pups – presumably due to the newfound bond with his offspring – his babies’ brains developed normally. But if the father was removed from the nest shortly after the birth of his pups, his newborns’ brains started to break down at the level of synapses, which are short chemical junctions in the brain that allow brain cells to communicate with each other.

All quite interesting. And you can also expect people who don't give a toss about who gets to make babies via reproductive technology to have a problem with it.

How does it smell?

Garlic good for blood pressure

Research trials by Dr Karin Ried and her colleagues from the University of Adelaide's Discipline of General Practice show that garlic could be used as an adjunct to conventional drugs for hypertension.

However, raw or cooked garlic, and garlic powder are not as effective in treating high blood pressure as aged garlic extract.

In a 12-week trial involving 50 people, Dr Karin Ried's team found that those with systolic blood pressure above 140 who took aged garlic extract capsules experienced an average systolic blood pressure 10.2mmHg lower than the control group, who took a placebo.

Sounds like a pretty good result. But how does aged garlic extract make me smell?

Cheer up, doc

A study on mental health issues shows suicide and depression are more prevalent in the medical profession than in the general public.

Research commissioned by the national depression initiative Beyond Blue has found women in the profession are two-and-a-half times more likely to commit suicide.

The study - to be presented in Adelaide today - also suggests rates of suicide for men in the medical professional are 25 per cent higher than the general public.

Story here.

Dangerous days

While in Sydney last week, we visited the Maritime Museum for the first time, and paid the extra to go on board the replica Endeavour. The photo a few posts back was of one of the windows into the (relatively large and well appointed) "Great cabin".

This proved to very interesting, and what I found most remarkable about it was the lack of headroom in the rear midshipmen mess/officers cabins. This leaflet from the museum doesn't make it clear how low it is, although it does mention that one area the marines slept in was 1.2 m high. I think the area I am talking about is a little higher, but believe me it's cramped, especially given my aversion to spending time in areas where I can't stand up straight. It was due to the ship having an extra deck built into it to accommodate the large crew to be taken on his expedition.

I was also surprised to be reminded of the large body count that Cook's most famous voyage racked up. Looking over the Wikipedia entry, we find:

* a sailor dragged overboard when he got entangled in the anchor chain

* two of Bank's servants freeze to death while trying to return to the ship in a snowstorm after rounding Cape Horn

* after stopping in Batavia, 30 (in a crew of 94) died from dysentery or malaria (including the ship's surgeon, and his brother)

* the museum leaflet linked above also mentions a marine who committed suicide by jumping overboard

Life was quite different in the 18 th century, hey? A wife saying goodbye to her husband at the dock when he set off on a long expedition seemingly had a pretty good chance of never seeing him again.

Torture not required

Reading terrorists minds about imminent attack: Brain waves correlate to guilty knowledge in mock terrorism scenarios

Yeah, the story's been out for a couple of weeks and maybe you've already read it, but I want to note it here for my own records.

It was pretty fascinating, if you missed it.

Both sides of the fence

I didn't get to see Four Corners last night, but I see from this report that Abbott is still trying to walk both sides of the fence, by making statements that will appeal to climate skeptics, but still making out that he is satisfied enough to spend money on reducing carbon.

If you ask me, as with his "I'm not a tech head" attitude to selling his broadband policy, Abbott comes across as lazy on detail. He'll grab a "big idea" of his own, such as his parental leave plan, and run with that as far as he can, but when it comes to anything with science content, it's all a shrug of the shoulders and admissions that he hasn't read much about it. (He said he started Plimer's disreputable book but didn't finish it. That in fact might be a good thing, but there is no indication that he has read material on the other side of the fence.)

Out there physics

Here's a paper on arXiv that I haven't had time to try and read yet, but I like the title:

Born in an Infinite Universe: a Cosmological Interpretation of Quantum Mechanics

Max Tegmark is one of the authors, and I certainly recognize his name.

Why I like the Tiger

Last week's trip to Sydney was taken on Tiger Airways again. This is at least the third time I've flown them: once to Adelaide, Melbourne and now Sydney.

The reason I fly them is, of course, the incredibly cheap fares you can find by subscribing to their email sale notifications. Apart from that, their generally bad reputation for reliability and service gives me a perverse thrill every time I take a successful trip on them.

I don't think any other airline in Australia is as ruthless with weight limits for both check-in baggage and carry on. What's more, the explanation of their rules in this regard on the internet is incredibly complicated. In some respects it seems to me that their website is positively misleading (referring to having to check baggage in 2 hours before the flight. In fact, no one will be at the counter in many of their terminals until 2 hours before the flight.) Telephoning them seems to end up putting you in contact with an overseas call centre, and the "telephone tree" didn't seem to recognize my number selections. Checking my reservation on line to make sure that I had paid for 15 kg of luggage when I booked the trip 9 months ago did not make it clear whether I had or not. (Hence the need for the lengthy call to the call centre.)

When you check in, there is normally some passengers at the desk having to do a rushed re-arrangement of the contents of their check in luggage to keep within the weight limits, or arguing over the fees they have paid.

Yet, all this means that when one successfully manages to book, pay for, and get on board a flight without drama (well, my wife had to give me some books from her carry on luggage to keep hers under 7 kg) there is the pleasant sensation of triumph over adversity, having dodged a bullet yet again, and flown this bus in the sky for a ridiculously cheap price.

Yes, I quite like Tiger Airways.

More details to come.

Home

I've been away again, and now have to work to pay for it. Trip report to come.

One thing I always notice when I get back from a holiday is that going through one's regular internet haunts to catch up over a week or so only takes up a small fraction of the time that one can waste on checking the same sites every day. Perhaps if the World Wide Web was open only on Sundays, work efficiency globally would increase sufficiently that a double dip recession could be avoided.

As for politics:

* Tony Abbott gave a very crook interview on Radio National this morning, sounding particularly evasive and devious about the company levy to pay for his Swedish parental leave plan. Labor should use parts of it for last minute advertising.

* I had been contemplating making an informal vote this election*, but now that Mark Latham has endorsed that idea, even that has become unappealing. Now I need to arrange to be bedridden with some 24 hour illness so that I can not vote without appearing to be taking a lead from a walking spleen vent. (By the way, I reckon Latham looks meaner and scarier now that he doesn't wear glasses. Must be the Superman effect that previously softened his appearance somewhat.)

* at least for the House of Representatives. For the Senate, the temptation to vote all over the enormous paper just to make life difficult for the vote counter may be too much.

Things to do

I'm going to be pretty busy this week.

Here are some things to do while I'm busy and (probably) not posting:

* watch a chemo affected Christopher Hitchens talk about his illness and God stuff here. (He doesn't get upset with people praying for his recovery, by the way.)

* read about Astana, the brand spanking new capital city of Kazakhstan. As the article says "it is the world's latest example of a rare but persistent type, the capital from zero. It is in a line that includes St Petersburg, Washington DC, Canberra, Ankara and Brasilia. " As it happens, I really like planned-from-scratch cities. I just wish some country would let Disney do their capital. Then again, when you look at this photo gallery of Astana, it does look quite a lot like that already. Cool.

* Contemplate my mistake in thinking that competitive eating was as silly as competitions get. Little did I know that Finland was out-stupiding America by hosting the Sauna World Championships, which has just killed one "competitor" and sent another to hospital. Funny what can happen when the test is to see who can last longest in a 110 degree C heat:

Ladyzhenskiy and Kaukonen had made it through to the final ahead of more than 130 other participants, but six minutes into the contest, judges noticed something was wrong with the Russian, and dragged both competitors from the sauna.

Both middle-aged men were seen to have severe burns on their bodies and were given first aid after they collapsed.

* watch some video of the aftermath of a huge mudslip/flood in a part of China.

* put in an offer for a Frank Lloyd Wright house in Pasadena. The price has already been reduced 35%; you might just get a bargain.

* be charmed by the twitching nose and rapid pace of the Rufous elephant shrew in this excerpt from the great documentary series Life currently showing on ABC on Sunday nights:

Concern from the other side of the world

The Independent runs a story about some evidence given to a Northern Territory inquiry about the pretty hopeless state of child welfare in aboriginal communities there.

It certainly does seem that resources are remarkably smaller than what I would have expected:

Claims that children are starving, or "failing to thrive", were contained in a submission to the inquiry in Darwin by child protection staff from the Northern Territory. They said resources allocated to indigenous communities were "grossly inadequate" and the spectacle of children who were failing to thrive was, to them, familiar.

The Darwin-based team covers a vast area and looks after 14,000 people, but has to make do with four welfare workers and four Aboriginal community workers. That level of staffing, combined with a "fly-in, fly-out approach", allows for "little more than superficial child protection responses", the inquiry submission said.

Staff also complained about the "incredible" volume of paperwork they had to plough through, saying: "We spend more time sitting at a computer than we do with our clients and their families."...

Meanwhile, Alice Springs Hospital has told the inquiry it is used by child protection workers as a "storehouse" for children awaiting foster placement. "[We are] an acute care facility, we are not able to provide appropriate supervision of children and their families," the hospital's submission said.

Dan Baschiera, a veteran social worker, told the inquiry he had seen child protection staff fresh from years of study and training "burn up" after a few months working in Aboriginal welfare. He accused the Northern Territory government of starving the child protection system of funds.

So, what's going on?

I didn't stay at the office yesterday, fearing the local clouds of wattle pollen. But then, the day before I felt generally ill, perhaps with a chill in the evening and feeling particularly tired. Is it in fact a virus, or was the tiredness from the (according to the woman in the pharmacy and the outside of the box) a non-drowsy antihistamine tablet that I took in the morning? (Strangely, the leaflet inside the box warned that for some people, it might make them sleepy anyway.)

Anyway, the nose didn't run much at home yesterday, and I generally felt not so bad while doing some work on my laptop on the dining room table. From that position, I got to watch the birds that come to the seed we leave outside (and to use the birdbath.) We now seem to have three regular types - a couple of bossy lorikeets, a pair of spotted doves, and now some top notch pigeons too. The lorikeets can't stand sharing the seed with the doves, and spend a lot of time trying to chase them away by hopping aggressively towards them. We've tried putting two plates of seeds out, then watched the lorikeets chasing pigeons away from both of them. [And now, as I type this, a spotted dove and top notch pigeon are having it out over a plate as well.] It's hard to make different species realise there's enough for everyone.

I've also noticed that spotted doves seem a particularly amorous breed. Doesn't matter what time of year it is, they seem up for it. But as far as nest building goes, they have extremely rudimentary ideas of what might be adequate. Lorikeets seem to be very private about their love life; we've never seen them do anything in or near the backyard. Maybe it's the mile high club only for them. Pigeons will try it anywhere.

I know getting wild birds too used to feeding is not supposed to be that good an idea, but we're only talking 6 regulars here, so I can't see we are going to cause any crisis to the local ecology.

So that's yesterday went; watching the local bird wars and amorous activities. Oh yeah, and peering into the computer as well. There are worse ways to pass the day.

The dreaded yellow flower

Near my office there are a few wattle trees. Every year, around this time, I either get sinus pain, or (as in this year) a full blown case of hayfever. It's then that I notice the wattles are in flower. They are evil.

Silly Brits

"Wild swimming" is apparently becoming popular in cold, polluted British waterways.  I did notice that Griff Rhys Jones seemed unusually keen on swimming in any murky brown stuff in his recent TV series about British rivers.  Odd people.

Short answer: no

The Christian Science Monitor asks the question "is the moon really a 'been there done that' world?"

The answer, of course, is "no". There was a forum at NASA last month which went into the details of why, and you can read about it at the link.

A solar salamander : Nature News

It turns out that a particular salamander incorporates photosynthetic algae in its cells:

Kerney reported that these algae are, in fact, commonly located inside cells all over the spotted salamander's body. Moreover, there are signs that intracellular algae may be directly providing the products of photosynthesis — oxygen and carbohydrate — to the salamander cells that encapsulate them.

This reminds me of the greenish, genetically engineered super bodies that were given to the aging soldiers in John Scalzi's "Old Man's War". If you're going to get into transhumanism, then incorporating chlorophyll would seem to be a good idea.

Babies at risk

Killing babies

Mary Beard discusses here on the practice in the Greco-Roman world of exposing unwanted babies. It's an unpleasant topic, but interesting.

Space airconditioning issue

I know very little about how the International Space Station works, despite my interest in all things spacey, but they have a cooling system that has gone on the blink:

The crew of the International Space Station have been forced to reduce power after half the cooling system suddenly shut down over the weekend.

Nasa officials insisted the three Americans and three Russians aboard were not in danger.

Urgent spacewalk repairs are being discussed for this week…

Flight controllers tried to restart the disabled ammonia pump early on Sunday but the circuit breaker tripped again.

Any repairs later this week almost certainly will involve replacing the faulty ammonia pump, a difficult job that would require two spacewalks, AP adds.

Two spare pumps are stored on the outside of the station.
