Hey! Hello! - How I Survived The Punk Wars (Official Video)
The first video from Ginger Wildheart's new Hey! Hello! "pop" music project. Very sweary and quite hilarious:


You can tell it's a Ginger song because I was singing along to the chorus halfway through the first listen :) And it amuses me greatly since the chorus could, very easily, be adopted by campaigners for Real Science against Psuedoscientific Bollocks.

Too tired for personal update. It's Techniques Week, which means several days of sitting through lectures, and two early morning starts. (10 am at College means leaving the house before 9, which means getting up at *mumble*...)

Instead, have some pictures which will make geeks laugh, weep, or both: Signs on chemistry labs at Georgia Tech in Atlanta.

What IS wrong with the picture? )

Do any of my friends want to go to the massive nerd tour featuring Robin Ince, Dr Ben Goldacre of Bad Science, the very pretty Prof Brian Cox, and ex-Imperialite Simon Singh? I'd want to go to the London date.

And yes, I know this clashes rather with my last post where I'm complaining about a total lack of spare energy to do anything social, but I'm rather hoping my chronic fatigue will have f'ed off again by May.

Everyone should read this:
This is an extract from BAD SCIENCE by Ben Goldacre. Published by Harper Perennial 2009. You are free to copy it, paste it, bake it, reprint it, read it aloud, as long as you don’t change it – including this bit – so that people know that they can find more ideas for free at www.badscience.net

The Doctor Will Sue You Now
Introduction )

Matthias Rath takes us rudely outside the contained, almost academic distance of this book. For the most part we’ve been interested in the intellectual and cultural consequences of bad science, the made-up facts in national newspapers, dubious academic practices in universities, some foolish pill-peddling, and so on. But what happens if we take these sleights of hand, these pill-marketing techniques, and transplant them out of our decadent Western context into a situation where things really matter?

In an ideal world this would be only a thought experiment. AIDS is the opposite of anecdote. Twenty-five million people have died from it already, three million in the last year alone, and 500,000 of those deaths were children. In South Africa it kills 300,000 people every year: that’s eight hundred people every day, or one every two minutes. This one country has 6.3 million people who are HIV positive, including 30 per cent of all pregnant women. There are 1.2 million AIDS orphans under the age of seventeen. Most chillingly of all, this disaster has appeared suddenly, and while we were watching: in 1990, just 1 per cent of adults in South Africa were HIV positive. Ten years later, the figure had risen to 25 per cent.

It’s hard to mount an emotional response to raw numbers, but on one thing I think we would agree. If you were to walk into a situation with that much death, misery and disease, you would be very careful to make sure that you knew what you were talking about. For the reasons you are about to read, I suspect that Matthias Rath missed the mark. Read more... )

PDF, Word document. Although they lack the links that are present in the online version.

I've copied & pasted the document into my livejournal not only because it says "Please distribute", but because I haven't seen anyone linking to it. Admittedly, I haven't been around much the past few weeks, but I've been skimming my list when I can. And I know lots of you care about the work of Medicins Sans Frontieres, prevention of HIV and treatment of AIDS. Clearly it's important and should be read. I originally said "everyone who cares about science, knowledge, ideas and humanity should read this", but I don't think it needs qualifiers. Just read it, ok?

Finding absolute RUBBISH on Wikipedia. The article on Cooperativity claims that cooperativity in oxygen binding to haemoglobin is caused "mainly" by the entropy difference. "the first oxygen has four different places where it can bind. This represents a state of relatively higher entropy compared with binding the last oxygen which has only one place where it can bind. Thus, in going from the unbound to the bound state, the first oxygen must overcome a larger entropy change than the last oxygen."

Well, that might be true (and I'm not altogether convinced that it is) - but it's certainly not the main reason for it. The lecture notes and textbook I have in front of me both describe cooperativity of oxygen binding in terms of conformational changes as deoxyhaemoglobin changes to haemoglobin. Deoxyhaemoglobin is square pyramidal around the Fe(II) ion, whereas oxyhaemoglobin is octahedral around Fe(III). The change in oxidation state of the iron ion reduces its ionic radius and allows it to move upwards into the porphyrin ring. That then pulls the rest of the protein into a different conformation, which affects the remaining haemoglobin monomers.

But I can't do a damned thing about the article right now. Firstly, I don't want to be accused of plagiarism when I hand in coursework that's identical to the Wikipedia article! Secondly, I don't want to provide a perfect model answer for the rest of the lazy-ass students to copy & switch a few words around in. (I can talk about it here because no one from college reads my livejournal. Anyway, I haven't given the full answer.)

So, the short story, Slow Life by Michael Swanwick - as found in The Mammoth Book of Best New SF 16 - has some egregious scientific mistakes. I don't know whether it's the author, or the editor, or the typesetter to blame - but one of these people has a fecking awful understanding of some basic concepts, to the extent the story made me angry. Get this: (by the way, I don't know how to do superscripts in livejournal, so superscripted stuff is typed as ^)
Still tugging at the ropes in the sequence uploaded by the engineers in Toronto, she scrolled up the chart of hydrocarbons dissolved in the lake.
Solute Solute mole fraction
Ethyne 4.0 x 10^-4
Propyne 4.4 x 10^-5
1,3-Butadiyne 7.7 x 10^-7
Carbon Dioxide 0.1 x 10^-5
Methanenitrile 5.7 x 10^-6

There are two things definitely wrong with that section of book, and a third possibly wrong.Read more... )

The BMI is a crock of shit at the best of times (how can you trust any measure that rolls fat, muscle and bone together as if it's the same thing?), and in children...? And as for the "fat police" monitoring who can eat what... words fail me.

ARGH!
