pharyngula | September 23, 2012I can take it no more. I wanted to dig deeper into the good stuff done by the ENCODE consortium, and have been working my way through some of the papers (not an easy thing, either: I have a very high workload this term), but then I saw this declaration from the Electronic Frontier Foundation.
On September 19, the Ninth Circuit is set to hear new arguments in Haskell v. Harris, a case challenging California’s warrantless DNA collection program. Today EFF asked the court to consider ground-breaking new research that confirms for the first time that over 80% of our DNA that was once thought to…

I've always been a big fan of personal freedom, which includes the freedom to speak your mind, say what you think, ask questions, be wrong, and learn. This is, after all, how we've all improved ourselves over our lives, as none of us were born knowing all that we've managed to acquire over our lifetimes.
And I've never had to have an official comment policy for all the years I've been blogging; the most I've ever…
jrosenhouse | September 20, 2012I had originally intended to devote this post to discussing some of the minutiae in Massimo Pigliucci's essay. In light of some of the comments on the previous post, however, I've decided it would be more useful to speak generally about why I get so annoyed when charges of scientism are casually thrown around.
I actually agree with some of Pigliucci's specific criticism's of Krauss. For example, in his exchange with Julian Baggini, Krauss said this:
Ultimately, I think our understanding of neurobiology and evolutionary biology and psychology will reduce our understanding of morality to…
pharyngula | September 19, 2012Our rebuttal to claims about the adaptive significance of the female orgasm has been published, as Zietsch & Santtila's study is not evidence against the by-product theory of female orgasm. I blogged about this a while back, and also dealt with some counter-arguments, and Elisabeth Lloyd thought my arguments were strong enough to be incorporated into a letter, so there you go…now I just need a badge or a t-shirt with a proclamation about my expertise on it.
Wallen K, Myers PZ, Lloyd EA (2012) Zietsch & Santtila’s study is not evidence against the by-product theory of female orgasm.…
drorzel | September 18, 2012There are a bunch of physics stories that I'd sort of like to write about, but don't have time for, and politics is oscillating between "darkly hilarious" and "indescribably depressing," so that's best left alone. So, here's some cute kid pictures instead.
SteelyKid has lately taken to telling all and sundry "This is my daddy. He's a scientist." She also sometimes adds "I'm a scientist, too!" so it seemed appropriate to go out with her and Do A Science.
As previously mentioned, she got a bunch of Backyard Safari gear from my aunt and uncle, which included a safari vest and a collapsible mesh…
pharyngula | September 17, 2012I know it's early, but I expect it to be the best thing for a few days yet. David Byrne writes about his love affair with sound, and I came away from it feeling like I'd both learned something new and that it fit well with other ideas I already had — it was a revelation to see how well music and evolution fit together.
Because music evolves. Byrne's thesis is that it evolves to fit its environment (sound familiar?), and that you can see the history of a genre of a music in its sound. It's all about the spaces it was played in, which shapes the kind of sound can be used effectively…and he…
oracknows | September 16, 2012As part of my ongoing effort to make sure that I never run out of blogging material, I subscribe to a number of quack e-mail newsletters. In fact, sometimes I think I've probably overdone it. Every day, I get several notices and pleas from various wretched hives of scum and quackery, such as NaturalNews.com, Mercola.com, and various antivaccine websites. I think of it as my way of keeping my finger on the pulse of the antiscience and pseudoscience wing of medicine, but I must admit that I don't really read them all, but they do allow me to know what the quacks are selling and what new…
catdynamics | September 14, 2012The OMB has reported on the effects of sequestration that will be triggered Jan 2013 unless Congress proactively changes the law before then.
Some time ago, Congress set itself a trap: in an attempt to look like they were dealing with government spending and the deficit, they passed a law that triggers automatic cuts to spending, unless Congress agrees and passes laws that make concomitant targeted cuts or revenue increases to decrease the deficit.
The nominal cuts are about $1.2 trillion, over a decade, cut from the projected budget in the out years, and are, by design flat across-the-board…
esiegel | September 14, 2012"I am always ready to learn, although I do not always like to be taught." -Winston Churchill
My very first time leading a classroom -- on my own -- was back in June of 2000. I was 21 years old, fresh out of college, and was teaching science in a middle school classroom. And I asked what I thought was an innocuous question, designed to pique their curiosity. I asked the class, "What are we -- you, me, and all human beings -- made of?"
I was expecting many possible answers common to all living things, ranging from "blood and guts" to cells, molecules, or atoms. From a scientific standpoint,…
oracknows | September 14, 2012The Human Genome Project (HGP) was one of the most massive scientific undertakings in recent years and, from a basic science and technology development standpoint, one of the most productive. The data gained formed the basis of the genomic revolution. And "revolution" is the right word. A mere 12 years after the human genome sequence was first published in papers in Nature and Science, we now have petabytes of sequence data pouring out of universities, research institutes, and genomics institutes. Sequencing a genome, which took several years to do for the HGP and cost billions of dollars,…
drorzel | September 13, 2012For her birthday, SteelyKid got a "Butterfly Keeper" set, which is basically a big mesh cylinder maybe two feet high and a foot in diameter. It came with a coupon for free live caterpillars for "Painted Lady" butterflies, which we duly sent away for. These came in a plastic cup full of caterpillar food, with paper across the top, and after eating most of the food, they climbed up and hung from the paper to form their chrysalises.
The instructions said to transfer the pupae to the mesh thing by pinning the paper to the top or side, which I did, with much delicate effort. Then, while moving…

Fusion Wallpaper
There comes a time in each person’s life when it is time to change the wallpaper. And the drapes, but we’ll focus on wallpaper here. And by wallpaper I mean the picture on your computer screen that is normally covered by icons and open windows. I came across a few neat individual wallpapers, as well as some good sources, and thought you’d like to see them. Since these wallpapers are from sites run by the artists who designed the wallpapers, it is appropriate that you go to those sites to get them, so here I’ll just show a few thumbnails but mainly talk about topics and…
drorzel | September 13, 2012Last week, in the post about fermion conduction, I left a reference hanging:
There’s nothing physically blocking the atoms from flying right through the channel– in fact, an atom that enters the channel will always exit the other side without slowing down along the way. This is termed “ballistic,” a term that will always have a special place in my heart thanks to an incident at my Ph.D. defense.
Which was what? Let’s just leave that hanging to see if anybody actually reads this far. I can explain it in a comment if people want to know.
A couple of people asked for the explanation in comments…
pharyngula | September 12, 2012I am getting quite impressed with the progress being made in organ reconstruction. New techniques have allowed amazing improvements in bioengineering that allow whole complex organs to be grown in a dish and then surgically reimplanted — and much of this research is being driven by our military ventures, which provide a steady supply of scarred, damaged, and mutilated veterans who need new body parts. There I read that scientists are developing procedures to regrow penises…how could I not look up that paper? So I did, and now I have the current recipe for building new penises — or at least,…

That was a scene from Monty Python's Holy Grail, demonstrating the lighter side of the plague. Who knew there was a lighter side of plague? Of course the darker side is easier to envision. This is a graph showing estimated human population over the last millenium. That enormous dip during around 1350 is not a result of people having less babies - as much as 10-20% of the entire human…
oracknows | September 6, 2012I must admit, there are times when I see something that someone else has written and, in a fit of intense envy, wish very much that I had written it. This is just such a time, and Tony Ballantyne has written just such a piece. Even better, his piece, entitled If only..., was published in Nature! That's right, the editors of Nature itself agree (or at least thought it interesting enough to publish): No science for you! What are you waiting for? Read it!
Of course, it's all a fantasy. In particular, I like the part asking why so many people are proud to be "bad at math" who would be utterly…
drorzel | September 6, 2012So, it's been a while, but let's see if we can't hit the ground running with a good physics post. There have been a few notable physics events since I went on hiatus, but for a return to physics ResearchBlogging, we'll go with something near and dear to my heart, ultracold atoms. Specifically, this Science paper (free arxiv version) about passing atoms through a narrow channel. This is a cool bit of subfield-crossing physics, so let's dust off the Q&A format, and go through it.
Hey, dude, long time no see. So, what's the deal with this paper? Well, the title pretty much tells you what's…
catdynamics | September 1, 2012Ah, semester has started, and with it comes the grind of studying for the big test, where callow highschoolers finally get to see if they can make it in the big leagues.
Here we see them in lecture:
One of the 30 or so in class lectures before the test
Yes, football players go to lectures.
About football, as well as whatever other subjects they are taking.
The coach gets up there, talks about football and shit, and they all listen, and nod, and maybe take some notes, and check their cool pics on facebook, and text their friends, and nap... afterwards they go their separate ways back to their…

pharyngula | August 30, 2012In my post bashing that silly article claiming to have figured out how endoskeletons evolved from exoskeletons, there was a good question buried in the comments, and I thought I'd answer it.
Are there any models pulled out of arses which explain the turtle's unique skeleton?
Yes! I mean, no, not pulled out of arses, but there is a lot of really good and persuasive research that uses evidence to show how the turtle skeleton evolved.
First, I can see how this question popped up in a discussion of the evolution of endo/exoskeletons: the turtle shell is an excellent example of an exoskeleton…
