Skin cancer risk

Look beyond the sun for skin cancer culprits, doctors warn

I was a bit surprised at the size of the risk increase:

Even things that seem unrelated to UV light—such as getting an organ transplant or a tattoo, or having an autoimmune disease—have been linked to skin cancer diagnoses.

People who've had an organ transplant have an extremely elevated risk for skin cancer—up to 200 times higher than others, according to Ibrahim. 

This stems from the medications that must be taken after a transplant to suppress the immune system. As a result, the immune system, which normally fights off growing cancer cells, may not be strong enough to do its job.

Organ transplant recipients should talk to a dermatologist to get an idea of their baseline risk for skin cancer and find out how often they need to be screened. Ibrahim said that some high-risk people who've had organ transplants need screening every three to four weeks.

Very witty, Bernard

I wish Crikey didn't have so much locked behind its paywall, but in any event, Bernard Keane's latest column is free to view, and has many witty lines.  First, talking about Labor:

...a party one step short of seriously considering consulting John Curtin via Ouija Board about how to resolve the Rudd-Gillard tension. It’s a party frozen in fear, terrified that any move it makes will be a mistake but painfully aware that doing nothing means a wipeout. The Liberals went through it in 2007, but Labor, as if to demonstrate that anything Tories can do, they can do better, are taking it to new levels.

Still, at least the Prime Minister has the the crucial Russell Crowe endorsement to add to Hugh Jackman’s support; with a visiting Arnie, the PMO could boast she had Gladiator, Wolverine and the Terminator. Then again, Tony Abbott doubtless has Dad and Dave and the cast of Division 4.

The next part, summarising the Coalition's policies, is pretty much spot on:

So far, there are two kinds of Abbott policies: those that mimic Labor, and those that look terrible. His Direct Action climate change policy is an open, albeit expensive, joke; his paid parental leave scheme is loathed by many within his own party and in the Nationals. His industrial relations policy is essentially a commitment to keep Labor’s Fair Work Act until the Productivity Commission gives him political permissions to go to voters with reforms; his broadband policy is, courtesy of Malcolm Turnbull, NBN lite, although at least 30% and probably more of Australian households will get the full-cream version.

And then the summary of the Coalition's "let's keep Gina happy and her cheques flowing in" Northern Australia project is really terrific:

 The Abbott vision is that northern Australia becomes a cornucopia of tourism, agriculture and mining, apparently unaware it’s tricky to have even two of those together let alone all three, and climate change is hardly conducive to any. Just ask tourism operators on the Great Barrier Reef.

In fact, this deep north stuff is downright weird. It’s not just Tony Abbott’s own big government DLP mindset emerging — it’s shared by Coalition MPs with functioning brains like Andrew Robb, the small government types at the IPA and far-Right miners like Gina Rinehart. It’s straightforward, Whitlamesque regional development, complete with Whitlam government policies like moving public servants around. It’s social and economic engineering on a huge scale; there’s not a market mechanism in sight. Indeed, there’s a utopian tone to the whole thing, not dissimilar to the early, funny socialist visions that were untainted by the nasty experience of the real world. It’s as if the Right wants to create a new Australia, one free of all the bad things about the current one like pesky unions, well-paid workers and restrictive environmental regulation, a place where entrepreneurs, with just a little help from taxpayer handouts, some government spending on infrastructure where no one currently lives and a few indentured public servants, can breathe the (admittedly, rather humid) air of freedom and create a more efficient economy.

Funny how Sinclair Davidson (and everyone else who blogs at Catallaxy) simply refuses to talk about the IPA's broad endorsement of this policy.

Embarrassing

I've just discovered, while googling my name for a work related purpose, that a young man from England has a twitter account in my name.  His tweets indicate he may well run the most boring twitter account in the universe, as it comprises mainly of short complaints:  "it's so cold today, hate this weather"  "when's my next pay rise?"  "I wish I was on holiday again".  To break up the monotony, there is the occasional "great time last night".  But it's nearly completely devoid of information. 

Come on, lad:   a namesake of me has to be more interesting.  And stop smoking.  (He thanked his Mum for a gift of fags.  D'oh.)

Local science makes me proud

Catalyst: Dengue Fever - ABC TV Science

I was very impressed with the state of science in Queensland as shown on Catalyst last night.  

The first story was about the promising looking plan to replace dangerous mosquitoes in Cairns with bred ones that will not carry the dangerous Dengue Fever.  

You can watch the video at the link (or see a transcript.)

The second story was about scramjet research based a the University of Queensland.  They've been plugging away at this for a long time, but still seem to be making advances.  

The story is not yet up on the Catalyst website, but I'll link to it when it is.

Quick and early success with vaccination

Sexually transmitted HPV declines in US teens

Since a vaccine against HPV was introduced in 2006, 56 percent fewer girls age 14-19 have become infected, said the research announced by the US Centers for Disease Control and published in The Journal of Infectious Diseases.

CDC Director Tom Frieden described the findings as a "wake-up call" that the vaccine works and should be more widely used. Currently, about one-third of girls age 13-17 are fully vaccinated.

 I wonder what percentage of 14 to 19 year old girls were formerly infected, though.  Certainly, go a bit older and the figures are big:

The CDC says about 79 million Americans, most in their late teens and early 20s, are infected with HPV, and every year some 14 million people become newly infected.

Hot where it counts

All-Time Heat Records Broken in . . . Alaska?! | Climate Central

It hasn't had attention in the Australian media, as far as I know, but recently Alaska has been having all time record heat, even while England continues with another wet and cool summer (and possibly may have more in the coming years.)

Someone in a comment somewhere on the net said it reminded them of chaos theory, which suggested some systems go through swings from one extreme to another until they settle into a new state.   That did ring a bell with me too.

The criteria as defined by Catallaxy

As far as I can tell, the main criteria by which Sinclair Davidson, Judith Sloan and others who post at Catallaxy for an economist to run Treasury (or the Productivity Commission) is that they have never been identified as expressing belief in, or have worked on, matters relating to environmental causes, and climate change in particular. 

Hence, Davidson says Treasury all started to go wrong when Ken Henry came in back in 2007.  

Of course, one would think that an economist who went out hard on a stagflation warning two years ago might be more circumspect in criticising Treasury for getting their recent years forecasts wrong, but no...

Awesome

More data storage? Here's how to fit 1,000 terabytes on a DVD

In The Conversation today:

 In Nature Communications today, we, along with Richard Evans from CSIRO, show how we developed a new technique to enable the data capacity of a single DVD to increase from 4.7 gigabytes up to one petabyte (1,000 terabytes). This is equivalent of 10.6 years of compressed high-definition video or 50,000 full high-definition movies.

They also point out:

 Some 90% of the world’s data was generated in the past two years.

Their two light beam technique, which reduces the "dot" size when burning a DVD, is said to be:

...cost-effective and portable, as only conventional optical and laser elements are use, and allows for the development of optical data storage with long life and low energy consumption, which could be an ideal platform for a Big Data centre.

I'm not sure if that means it won't be turning up on a home PC, but still, it sounds a remarkable advance.

Uri Geller psychic spy? The spoon-bender's secret life as a Mossad and CIA agent revealed - Features - Films - The Independent

This sounds very improbable, but interesting:

We may know him for spoon bending antics and for his lengthy friendship with pop star Michael Jackson but showbiz psychic Uri Geller has seemingly had a lengthy second career as a secret agent for Mossad and the CIA, albeit one that was more Austin Powers than James Bond.

Geller was at the Sheffield Doc Fest this week for the premiere of Vikram Jayanti’s The Secret Life Of Uri Geller – Psychic Spy?, a new film that offers compelling evidence of his involvement in the shadowy world of espionage.

“Uri has a controversial reputation. A lot of people think he is a fraud, a lot of people think he is a trickster and makes things up but at the same time he has a huge following and a history of doing things that nobody can explain,” Jayanti says of his Zelig-like subject....

 The doc leaves a question mark in its title but provides so much background evidence that we are left in little doubt that even its most outlandish assertions are rooted in truth. Whether or not Geller had psychic powers, US security forces were certainly prepared to take a very hefty wager on him.

The documentary doesn't just rely on Geller's claims (in fact it says he is guarded in what he says):

Jayanti didn’t rely on Geller’s own cryptic testimony. Instead, he spoke to the high-level officials involved in recruiting and using him. These include scientists from The Stanford Research Institute as well as senior CIA operatives. Among the interviewees with first hand knowledge of Geller’s psychic spying activities are former CIA officer Kit Green, Apollo 14 astronaut Edgar Mitchell (the sixth man to walk on the moon), physicists Russell Targ and Hal Puthoff, and retired US army colonel John Alexander (of The Men Who Stared At Goats fame). A Brit, Nick Pope, once the British Government’s UFO boffin, also puts in an appearance. 

Hmmm.  Given that most of those named are prominent as believers in the paranormal, I wonder how reliable some their testimony might be.

Anyway, sounds well worth watching.

A comment made in absentia

I have a comment awaiting moderation for Catallaxy, where Julie Novak has attempted to answer the question "why are there no libertarian countries":

* Julie may well have read of this article elsewhere (it was getting a lot of publicity in the US), but I was the first to raise it at Catallaxy in an open thread some days ago. It attracted little comment, apart from the “just piss off” variety, and daddy dave accused it of being deliberately provocative to dare raise it at a libertarian themed site (even though, as many others now point out, the threads are dominated by conservatives.) This is an example of the completely out of whack treatment yours truly receives at the blog – it was an interesting argument well deserving of comment, but because I am the one to raise it, I am the one who deserves punishment.

* Isn’t it gob smackingly ironic for the complaints at this blog regarding the alleged crushing nanny statism which Australians are suffering under that Julie is citing recent research ranking the country high in the matters of economic and personal freedoms? I haven’t been able to download the paper at the link, but people who can should perhaps explain why it doesn’t support my contention that the blog is full of exaggerating panic merchants?

Oh, boo hoo

Of course, confirming that the Labor politicians who are still fighting the war for a Rudd return are not quite right in the head, Doug Cameron and Kim Carr have lined up to pretty directly condemn Gillard for seeing that Crossin loses her job.

But quite frankly, that's politics, isn't it?   People sometimes lose pre-selection for someone they think less deserving.

And after all - it's not as if Crossin hasn't had a good run.  In the Senate since 1998, and what sort of pension will she retire on?:

TERRITORIANS shouldn't feel too sorry for Trish Crossin following her dumping from the Senate.
She will get an annual tax-free pension of more than $100,000 a year and five free business class flights a year.

Oh, it's a right tragedy for her, that is.

Lift cables, skyscrapers, and space

Lifts and skyscrapers: The other mile-high club | The Economist

Here's another interesting piece up at The Economist website:

This week Kone, a Finnish liftmaker, announced that after a decade of development at its laboratory in Lohja, which sits above a 333-metre-deep mineshaft which the firm uses as a test bed, it has devised a system that should be able to raise an elevator a kilometre (3,300 feet) or more. This is twice as far as the things can go at present. Since the effectiveness of lifts is one of the main constraints on the height of buildings, Kone’s technology—which replaces the steel cables from which lift cars are currently suspended with ones made of carbon fibres—could result in buildings truly worthy of the name “skyscraper”.

The problem with steel cables (or “ropes” as they are known in the trade) is that they are heavy. Any given bit of rope has to pull up not only the car and the flexible travelling cables that take electricity and communications to it, but also all the rope beneath it. The job is made easier by counterweights. But even so in a lift 500 metres tall (the maximum effective height at the moment) steel ropes account for up to three-quarters of the moving mass of the machine. Shifting this mass takes energy, so taller lifts are more expensive to run. And adding to the mass, by making the ropes longer, would soon come uncomfortably close to the point where the steel would snap under the load. Kone says it is able to reduce the weight of lift ropes by around 90% with its carbon-fibre replacement, dubbed UltraRope.

The article does note at the end that the development suggests that space elevators may be do-able:

Nor need carbon-fibre lift-cables be confined to buildings. They could eventually make an idea from science fiction a reality too. Space lifts, dreamed up in the late 1950s, are a way of getting into orbit without using a rocket. Building one would mean lowering a cable from a satellite in a geosynchronous orbit above the Earth’s equator while deploying a counterbalancing cable out into space. The cable from Earth to the satellite would not be a classic lift rope because it would not, itself, move. But it would perform a similar function of support as robotic cars crawled up and down it, ferrying people and equipment to and from the satellite—whence they could depart into the cosmos.

I'm guessing that the strength of this new cable has some way to go yet.

But as it happens, I was idly wondering recently about whatever happened to the idea of a "skyhook" system for helping get things into low earth orbit.  

I always thought the idea of space plane catching a ride up at the end of skyhook sounded like a good idea, and I wonder whether the strength of the Kone cable is enough for the job.   (Although a skyhook presumably needs to be rigid, not flexible like a lift cable.  I wonder if that is a problem?)
