I just read this great science-fiction story. It's about how machines take control of humans and turn them into zombie slaves.
So instead of us controlling machines, they control us? Pretty scary idea.
I''ll say…HEY What time is it? My TV show is on.

Horrifyingly delusional anti-vaxxers in Australia

Category: Bad scienceStupidity

Take a look at the ad copy for this evil book by a friend of Meryl Dorey, the anti-vaccination kook.

"Marvellous measles"? "Embrace childhood disease"? This is rank madness. Here is what WHO says about measles:

  • Measles is one of the leading causes of death among young children even though a safe and cost-effective vaccine is available.
  • In 2008, there were 164 000 measles deaths globally - nearly 450 deaths every day or 18 deaths every hour.
  • More than 95% of measles deaths occur in low-income countries with weak health infrastructures.
  • Measles vaccination resulted in a 78% drop in measles deaths between 2000 and 2008 worldwide.
  • In 2010, about 85% of the world's children received one dose of measles vaccine by their first birthday through routine health services - up from 72% in 2000.

Measles kills children. The reason these loons can babble about measles as if it were a harmless game that strengthens your immune system is that world-wide vaccination campaigns have been so effective in reducing the incidence of the disease, and because children who are healthy and have good nutrition are very likely to survive it. So what Stephanie Messenger and Meryl Dorey propose to do is to put sick, immuno-compromised, and hungry children at far greater risk of death, and make their own spoiled children miserable and contagious for a few days to a week, and also put them at a lesser risk of death, all so they can smugly promote their hare-brained cause.

Something else that irritates me about these people is that often they align themselves with the left — it's gormless liberals who readily buy into this nonsense. Another scandal developing in Australia is that the Woodford Folk Festival has invited Meryl Dorey to speak. It looks like a big event, and there among the environmentalists and local foods proponents and polynesian and aboriginal singers, is this great stinking turd of a woman advocating infecting small children with awful diseases. This Meryl Dorey:

She has described measles (the disease which has killed more children than any other in the history of the world) as "benign;" she suggested the slogan "Shaken Maybe Syndrome" as a way of implying that Shaken Baby Syndrome does not exist but is always damage caused by vaccines; she provided strong support to a man imprisoned in the US for the murder of a ten-week-old boy, her support being based on the idea that the dreadful injuries to the child had to be the effects of a vaccine, not the actions of a violent man; she is on record as an AIDS denier; she said on television that "whooping cough didn't kill us thirty years ago and it's not kill anybody today". If she isn't implacably opposed to vaccinations then she hides any other position well.

The festival sounds like fun, but if I were in the region, nothing could persuade me to attend — it's poisoned through and through by its endorsement of a child-killing monster who will be given a stage to lie from.

The Pluto objection

Category: Creationism

I'm so sorry, Kentucky. How do you end up with such ignorant school superintendents?

Ricky Line is concerned because his school district is teaching the facts of evolution.

"I have a very difficult time believing that we have come to a point ... that we are teaching evolution ... as a factual occurrence, while totally omitting the creation story by a God who is bigger than all of us," he wrote. "My feeling is if the Commonwealth's site-based councils, school board members, superintendents and parents were questioned ... one would find this teaching contradictory to the majority's belief systems."

"My argument is, do we want our children to be taught these things as facts? Personally, I don't," Line said. "I don't think life on earth began as a one-celled organism. I don't think that all of us came from a common ancestor ... I don't think the Big Bang theory describes the explanation of the origin of the universe."

So a school superintendent rejects all of modern science. The only novel thing here is his excuse:

The vast majority of scientists contend that evolution is an accepted cornerstone of modern science, and that there is no real scientific debate over the concept.

Line counters that "it's interesting that the great majority of scientists felt Pluto was a planet until a short time ago, and now they have totally changed that. There are scientists who don't believe that evolution happened."

That argument might work a little better if Pluto had winked out of existence when it was retitled…but it still whirls about the sun. Just as life on earth keeps bubbling up, and descent with modification keeps on happening.

And just like bible-thumping American yokels keep meddling in our children's educations.

Once again, I am embarrassed to be an American

Category: Communicating scienceEnvironmentMediaPoliticsStupidity

I have really been looking forward to seeing David Attenborough's latest, Frozen Planet, here in the US. I've seen brief snippets of the show on youtube, and like all of these big BBC nature productions, I'm sure it's stunning. And then I hear that the Discovery Channel has bought the rights! Hooray!

But wait, experience cautions us. Remember when American television replaced Attenborough's narration with Sigourney Weaver? And <shudder> Oprah Winfrey? ANd when the Oprah version dropped the references to evolution? What kind of insane butchery would they perpetrate this time around?

Well, the word is out. The Discovery Channel only bought 6 of the 7 episodes. They dropped the seventh because…it talks about global climate change.

Goddamnit.

It's not just our dimbulbs in government, it's active collusion by the media to suppress scientific evidence because it might be unpopular with our undereducated booberati. Jerry Coyne suggests that you contact the Discovery Channel's viewer relations page and express your displeasure. I will not be watching a neutered version of the program on Discovery; instead, I'll wait until I can pick up the BBC DVDs.

You know what else is annoying about this? My wife and I are having a pleasantly quiet evening at home, and what she's been doing is watching youtube videos…of David Attenborough. She's been gushing over these spectacular videos all night long, and I swear, I'm beginning to feel pangs of manly jealousy. At least I get to tell her that the American media has decided that he's seditious and dangerous.

And that will probably make him even more attractive. I can't win.

Just to end on a more pleasant note, Mary almost orgasmed over this one. You'll like it too. Too bad the Discovery Channel thinks you hate reality.

Bad science in the British Journal of Psychiatry

Category: Bad science

Would you believe that ""the largest, most definitive analysis of the mental health risks associated with abortion, synthesizing the results of 22 studies published between 1995 and 2009 involving 877,181 women, of whom 163,831 had abortions" has determined that "abortion harms women's mental health"? It concludes that "10% of all mental health problems and 34.9% of all suicides in women of reproductive age" are caused by abortion. Here's the author's own summary of the results.

Women who had undergone an abortion experienced an 81% increased risk of mental health problems, and nearly 10% of the incidence of mental health problems was shown to be attributable to abortion. The strongest subgroup estimates of increased risk occurred when abortion was compared with term pregnancy and when the outcomes pertained to substance use and suicidal behaviour.

Those numbers are so extravagantly extreme that there ought to be alarm bells going off in your head right now, and the research had better be darned thorough and unimpeachably clean.

As it turns out, it isn't. The author of the paper, Priscilla Coleman, is an anti-abortion advocate, and 11 of the 22 studies sampled for the meta-analysis are by…Priscilla Coleman. Methinks there might be a hint of publication bias there, something that has been confirmed statistically by Ben Goldacre.

Jim Coyne has carried out a thorough dissection of the paper, exposing the statistical games she played with the data.

If you examine Figures 1 and 2 in Coleman's review, you can see that she counts each of her own studies multiple times in her calculation of the effects attributable to abortion. This practice was also roundly criticized in the E-letter responses to her article because each study should only be entered once, if the conditions are met for integrating results of studies in a meta-analysis and providing a test of the statistical significance of the resulting effect size. This may sound like a technical point, but it is something quite basic and taught in any Meta-Analysis 101.

Coleman's calculation of overall effect sizes for the negative mental health effects of abortion involve integrating multiple effects obtained from the same flawed studies into a single effect size that cannot accurately characterize any of the individual effects - anxiety, depression, substance abuse, and suicide - that went into it. Again we are encountering a nonsensical statistic.

And just how good were the papers that Coleman chose to include in her meta-analysis? She claims they were the best, and that others were excluded because of their poor quality, but it seems other investigators hold her work in low esteeem.

…an APA task force report did find that Coleman studies--the ones she included in her meta analysis--had inadequate or inappropriate controls and did not adequately control for women's mental health prior to the pregnancy and abortion. A similar verdict about Coleman's work was contained in the draft Royal College of Psychiatrists report that also considered the bulk of her work too weak and biased to be entered into an evaluation of the effects of abortion on mental health.

I did find this comment by Jim Coyne bitterly amusing.

Readers should be to assume that the conclusions of a meta-analysis published in a prestigious journal are valid. After all, the article survived rigorous peer review and probably was strengthened by revisions made in the authors' response to a likely "revise and resubmit" decision.

Obviously, you can't assume that. This is a case where the editors and reviewers failed to do their jobs, and that happens way too often…and now this study has been thoroughly politicized and is being touted by the anti-abortion wackaloons to argue that abortion must be banned…for the good of the women. Which is probably one of the few times they've given a damn about the women involved.

But if you want a good, straightforward summary of why Coleman's paper should have been rejected, that last link is it.

Game over, man. No cat video can ever be as awesome as this: two mimic octopuses mating.

It's like watching a nest of snakes break out into a barroom brawl. It's also the most erotic thing I've ever seen on the internet.

I'm done, almost!

Category: AcademicsPersonal

Oh, man. I just finished my last lecture for this semester — this was a rough term, and I feel like I just barely dragged myself over the finish line. The big strain came from the fact that I revamped everything: I completely changed the content of my neurobiology course, with a new textbook, a new emphasis, and a different direction for the labs, and some stuff worked and some stuff failed catastrophically (the last few weeks of the lab in particular were a disaster). I offer this course again in two years, and I think I can fix the bad parts by then. I also patched up a lot of material in my Fundamentals of Genetics, Evolution, and Development course; not so much changes in lecture content, but stretching to reach out and get the students interacting more. That worked entirely — I got some significant improvements in average exam scores which I will take complete credit for, although it could just be that our incoming freshman class was full of geniuses this year. I also got much more disciplined in the writing course, and imposed a whole series of step-by-step deadlines on the big term paper. It required a bit more effort during the term, but the payoff is now — I'm not getting any papers dumped cold on my desk for grading, they've all been fussed over already.

It's tiring, though. Show business is hard work; getting up and doing 4 or 5 lectures a week (and about half of them new) is exhausting. It would be much easier to just write this stuff. Why didn't anyone tell me that a career in science involved so much singing and dancing?

My neuro students are all done with their bloggery now, and here's the final list of neurobiology weblogs I forced them to start. Some might fade away after this, others may move on to new sites, some might keep going. However it works out, this can be my little public monument to Fall 2011. Stop by and congratulate them on surviving a whole semester with Old Man Myers.

Next: I've got final exams to give, a nice break to catch up on deadlines, and lots of preparation for next term to do. Spring will be worse, with an all-new, starting from scratch course in cancer biology to teach.

For now, I'm going into seclusion for a bit to wrap up some extracurricular writing that must get done right now. It's not much of a celebration yet.
