Chris is clearly trying to drum up support among My People*.
*My People. You know, godless nature lovers who like turtle sex. We’re a h u g e demographic.
OK, that settles it. I’m in the wrong research field.
They found breasts moved in a 3D figure of eight and that uncontrolled movement strained fragile tissues and ligaments.
The study suggested as a woman runs a mile, her breasts bounced 135 meters.
The report found each breast moved independently of the body by an average of 9cm for every step taken on the treadmill.
With the average breast weighing between 200 and 300 grams, this movement puts great stress on the breast’s fragile support structure—the outer skin and connective tissues known as Cooper’s ligaments.
I suspect the analysis was…mesmerizing.
The wording was a little unfortunate—I pictured the subject dribbling a pair like basketballs as she runs.

Ohio State Board of Education has an ID lesson plan on the books. Ohio Citizens for Science has been fighting it, but at a recent meeting, the Board voted to maintain it’s anti-science position.
A friend sent this scan from the Columbus Dispatch. It does show the ignorance, the contempt, and the arrogance of the creationists.
“Richard Baker, an avowed creationist and vice president of the OBE,
disagrees. ….Baker accused the scientific community of wasting time
debating the plan. “We spend all this malarkey and baloney when 99 percent
of all the people who are taught this have nothing to do with the rest of
their lives. These scientists, they don’t care about wasting their own time
or anybody else’s time. In business we don’t waste time. To me, [the lesson]
is not a big deal.” According to Baker, the real reason scientists want to
do away with the lesson plan is, as he said to a group of scientists at a
board meeting concerning the lesson plan, “[They] think [they] know
everything. [They’re] just a bunch of paranoid, egotistical scientists
afraid of people finding out [they] don’t know anything.””
That’s a man who does not belong on the Board of Education.
Honesty is very seldom heard nowadays, especially from a politician. So, I am not going to break from political tradition. My name is Jonathon “The Impaler” Sharkey, Ph.D., L.D.D.D. I am a Satanic Dark Priest, Sanguinarian Vampyre and a Hecate Witch. My Magikal Path name is: Lord Ares.
The first two sentences taken together are a little amusing, but I’m sill not planning to vote for the guy. He’s a former Republican (surprise!), but has now founded his own party, VWP. The Vampires, Witches, and Pagans Party.
Are you wondering how he got his nickname?
As previously stated by me, any Terrorist who commits
an act of Terrorism in Minnesota while I am governor,
will be Impaled by me in front of the State Capital.
He’s also planning to run for president in 2008. I could see him stepping into GW Bush’s shoes easily. The Religious Right might not care much for him, but otherwise, he’s the perfect representative of Republican sentiments.
Every biology student gets introduced to the chordates with a list of their distinctive characteristics: they have a notochord, a dorsal hollow nerve cord, gill slits, and a post-anal tail. The embryonic stage in which we express all of these features is called the pharyngula stage—it’s often also the only stage at which we have them. We terrestrial vertebrates seal off those pharyngeal openings as we develop, while sea squirts throw away their brains as an adult.
The chordate phylum has all four of those traits, but there is another extremely interesting phylum that has some of them, the hemichordates. The hemichordates are marine worms that have gill slits and a stub of a tail. They also have a bundle of nerves in the right place to be a dorsal nerve cord, but the latest analyses suggest that it’s not discrete enough to count—they have more of a diffuse nerve net than an actual central nervous system. They don’t really have a notochord, but they do have a stiff array of cells in their proboscis that vaguely resembles one. They really are “half a chordate” in that they only partially express characters that are defining elements of the chordate body plan. Of course, they also have a unique body plan of their own, and are quite lovely animals in their own right. They are a sister phylum to the chordates, and the similarities and differences between us tell us something about our last common ancestor, the ur-deuterostome.
Analyzing morphology is one approach, but this is the age of molecular biology, so digging deeper and comparing genes gives us a sharper picture of relationships. This is also the early days of evo-devo, and an even more revealing way to examine related phyla is to look at patterns of gene regulation—how those genes are turned on and off in space and time during the development of the organism—and see how those relate. Gerhart, Lowe, and Kirschner have done just that in hemichordates, and have results that strengthen the affinities between chordates and hemichordates. (By the way, Gerhart and Kirschner also have a new book out, The Plausibility of Life (amzn/b&n/abe/pwll), which I’ll review as soon as I get the time to finish it.)
Well. If I were a “single-celled, parasitic protozoan known for infections that sometimes last for years, which may be accompanied by vague gastrointestinal distress or dysentery—complete with blood and mucus in the stool”, I’d feel grossly insulted by this comparison.
(I’m one to talk…”pmyers” turns up in a trypanosome.)
