The Coalition Against Biopiracy has announced their winners for the 2006 Captain Hook Awards for Biopiracy, and they're a hoot. We already knew that Darwin was a pirate, but now we learn that so are Craig Venter and Google. What are their crimes? Venter is accused of being the "Greediest Biopirate", and Google is accused of being the "Biggest Threat to Genetic Privacy". I have some more details on these charges below the fold, in addition to showing why the Coalition Against Biopiracy needs to walk the plank.
Venter is accused of:
"undertaking, with flagrant disregard for national…
pharyngula | March 30, 2006Our speaker at Tuesday's Café Scientifique, Nic McPhee, has a blog, and gives the speaker's side of the event. He's exactly right that our big problem out here is improving community involvement, and getting some interaction with the townie side is going to be one of my goals in setting up next year's series.

The New England Journal of Medicine sometimes provides great stuff to read over breakfast, like this story of a man who returned from a trip to Hungary with his guts infested with worms, Enterobius vermicularis. OK, so it's not much of a story…but the cool thing is that they provide a movie clip of his colonoscopy, and you can watch the worms writhe.

drorzel | March 29, 2006Sean Carroll offers another installment of unsolicited advice about graduate school, this time on the topic of choosing what school to attend once you're accepted (the previous installment was on how to get into grad school). His advice is mostly very good, and I only want to amplify a few points here.
Below the fold, I will list the three most important decisions you will make in choosing a graduate school:
Choosing a research advisor.
Choosing a research advisor.
Choosing a research advisor.
It might be a slight overstatement to say that the choice of advisor is the single most important…
pharyngula | March 29, 2006You all may recall the memorable, late Tito the wonder dog. Hank Fox has done something thought-provoking: he has frozen away some of Tito's cells, on the chance of cloning him.
At 325 degrees below zero, the essence of Tito sleeps.
I got a call today from Genetic Savings & Clone, the company that stores tissue samples of pets, and they told me the culturing of the samples I'd sent them was successful. I now have about 10 million cells waiting for the future moment — if ever — when the technology and the money coincide to allow me to clone him.
This is a personal decision, and I wouldn't…
drorzel | March 29, 2006If you've ever read and been confused by computing theory books, you might appreciate the discussion of Turing machines at Good Math, Bad Math. Or, if you're already happy with the whole Turing machine thing, you might just like that post for the link to a Turing machine simulator applet. Either way, it's all good.
pharyngula | March 28, 2006We're having another Café Scientifique here in Morris this evening—come on down! Nic McPhee of the Computer Science discipline (who also has a weblog, Unhindered by Talent) will be discussing "Privacy, security, and cryptography: What happens to your credit card number on-line, and is that e-mail really from your boss?". It is open to everyone, of course, and is being held at the local coffeeshop, the Common Cup, from 6:00 to 8:00 this evening.
pharyngula | March 27, 2006There is a most excellent online seminar on Mooney's Republican War on Science going on over at Crooked Timber. The usual gang is reviewing it, with the addition of the inestimable Tim Lambert and Steve Fuller. Wait a minute…Steve Fuller? That Steve Fuller? Steve Fuller. Steve Fuller!
Jebus.
I saw some glimmers of some interesting ideas at the start of Fuller's ultimately long-winded essay, but they expired even before he started defending the "positive programme behind intelligent design theory" and collapsed into tired pro-creationism mode. When he called George Gilder and Bruce Chapman "…
pharyngula | March 27, 2006Here's an excellent case: applying evolutionary principles to cancer improves diagnosis. You are a collection of (mostly) dividing cells, a population moving forward in time, and understanding that explains a great deal about how changes, like cancer, can occur.
oracknows | March 26, 2006How depressing.
Right there on the front page of the New York Times this morning:
SACRAMENTO -- Thousands of schools across the nation are responding to the reading and math testing requirements laid out in No Child Left Behind, President Bush's signature education law, by reducing class time spent on other subjects and, for some low-proficiency students, eliminating it.
Schools from Vermont to California are increasing -- in some cases tripling -- the class time that low-proficiency students spend on reading and math, mainly because the federal law, signed in 2002, requires annual exams…
drorzel | March 24, 2006Reading Dylan Stiles's blog yesterday reminded me of a post I wrote last summer about how to approach student talks about synthetic chemistry. Since evil spammers have forced us to turn off comments to the old site, I'll reproduce the original below the fold:
Summer days are here again, which means the return of the
annual summer student research seminar. There's a local tradition
of having all the students doing on-campus research give 15-minute
talks to all the other summer students. In principle, I think this
is a very good idea, as it gives the students some practice at
public speaking,…
drorzel | March 24, 2006A reader emails to ask if I can make sense of this announcement from the European Space Agency:
Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity and could help physicists to make a significant step towards the long-sought-after quantum theory of gravity.
Just as a moving electrical charge creates a magnetic field, so a moving mass generates a gravitomagnetic field. According to Einstein's Theory of…

drorzel | March 21, 2006Alex Palazzo offers a taxonomy of biologists, and takes some heat in the comments for leaving people out or mischaracterizing subdisciplines. This reminded me that I did a similar post about physics quite some time ago-- almost four years! That's, like, a century in blog-time...
I'll reproduce the geek taxonomy after the cut, and clean up a few rotted links.
Geek Taxonomy
So, what, exactly, is it that I do for a living? (Other than come in to work every morning and respond to disgruntled emails about the grades I hand out, that is...). Depending on the context, I have a bunch of different…
pharyngula | March 21, 2006As an exercise in futility, The Daily Transcript tries to categorize disciplines of the life sciences. Although there is a general air of truth to what he's saying, the problem is that, unlike the members of the Tree of Life, academic disciplines are free to hybridize and accumulate and change, so instead of blurry but recognizable terminal branches, you end up with an anastomosing rete, and no one can sort out precisely who is what.
For instance, I've got training as a neurophysiologist (electrodes everywhere!), a cell biologist (painting organelles different colors and watching the glowing…
drorzel | March 21, 2006Janet Stemwedel over at Adventures in Science and Ethics has a new post on experiment vs. theory:
Someone makes a comment about hot water making ice cubes faster than cold water. Someone else, familiar with thermodynamics, explains in detail why this cannot be the case. No actual ice cube trays risk harm, since none are ever deployed in resolving the dispute.
I loves me some thermodynamics. But, why not clear some space in the freezer to do a side-by-side comparison of the ice cube tray filled with hot water and that filled with cold water? Doing an experiment certainly doesn't preclude…
pharyngula | March 20, 2006
Not all the email I get is from cranks and creationist loons. Sometimes I get sincere questions. In today's edition of "Ask Mr Science Guy!", Hank Fox asks,
I was thinking recently about the fact that wax collects in one's ears, and suddenly thought to be amazed that some part of the HUMAN body produces actual WAX. Weird. Like having something like honeybee cells in your ear.
And then I started to think about what sorts of other ... exudates the human exterior produces. Mucus, possibly several different types (does the nose itself produce more than one type?). Oils, possibly several…
pharyngula | March 20, 2006
What has always attracted me to developmental biology is the ability to see the unfolding of pattern—simplicity becomes complexity in a process made up of small steps, comprehensible physical and chemical interactions that build a series of states leading to a mostly robust conclusion. It's a bit like Conway's Game of Life in reverse, where we see the patterns and can manipulate them to some degree, but we don't know the underlying rules, and that's our job—to puzzle out how it all works.
Another fascinating aspect of development is that all the intricate, precise steps are carried out…
pharyngula | March 16, 2006Both Twisty and Amanda seem a bit weirded out by this news that the fetus can be viewed as a kind of parasite. This story has been around long enough that a lot of us just take it for granted—I wrote about the example of preeclampsia a while back.
There are worse feminist-troubling theories out there, though. In particular, there is the idea of intersexual evolutionary conflict and male-induced harm. In species where there is some level of promiscuity, it can be to the male's evolutionary advantage to compel his mate to a) invest more effort in his immediate progeny, b) increase her short-…
drorzel | March 16, 2006I've seen the idea of an "Opposite Day" popping up lots of places in the political blogosphere (most recently from Big Media Matt and Will Wilkinson), and it sounds sort of cool. The idea is that you commit to writing blog posts on topics chosen by readers, taking the opposite position from what you would normally argue.
The problem is, this really only works for people blogging about the humanities and social sciences, where you can sensibly argue both sides of any position, or invent entirely new sides at a whim. Us science types are a little more constrained by reality. We've got all these…
