It’s Tuesday, the 22nd of January, and this is the first day of classes at UMM. I’m teaching the introductory biology course again (Fundamentals of Genetics, Evolution, and Development), my big core lab course in genetics, and an upper level class in science writing, and that’s enough.
As is usual for me, I tremble in a state of dread at the start of the long season of lectures and labs, but once I charge in and get started I’ll probably be surprised when I look up and notice it’s May already.
This is the time — you can give feedback on the Minnesota science standards, and you can also apply to be on the standards writing committee. Here’s where you have a chance to make a difference.
The Minnesota Department of Education is now soliciting feedback from the public on the current Science Standards via an online survey. The survey will be open until February 21, 2008.
First, review the current Science Standards on the Science Standards Web page.
Then take the Science Standards online survey.
Applications are also being accepted for individuals interested in serving on the Science Standards Revision Committee. Before applying to the committee, please read the Assumptions and the Timeline documents posted on the MDE Science Standards Web page. Serving on the committee means a commitment of at least one meeting a month, from March 2008 through February 2009. The initial 2-day meeting is scheduled for March 4-5, 2008, and is required of all committee members. Applicants who are selected for the committee will be notified on or before February 21, 2008. (Applications accepted January 8-21, 2008.)
First, read the Assumptions and the Timeline documents posted on the Science Standards Web page.
Then, apply for the Science Standards Committee.
If you have questions about the Science Standards or the revision process, please contact Clark Erickson, State Science Education Specialist, at 651-582-8753.
Please share this information with your district and school staff, particularly teachers or administrators involved in science education.
If you understand the science and want to contribute to the next set of standards for the state of Minnesota, get to work. Remember, the current standards were written under the malignant influence of Cheri Yecke, and they’re good given the difficulty of the conditions, thanks to the hard work of the previous committee. We can make these standards a shining example for the rest of the country this time.
I’m not too impressed with the curriculum, but heck, they’ve got a great mascot, so I’m sure students will apply.
The Fall semester is winding down — this is the last week of classes — so it’s time to start thinking about the Spring term.
Ugh. I don’t want to. This term has been driving me sufficiently insane as it is.
But anyway, if you’re a student thinking about all the money you’ll have to be spending on textbooks, here’s a list of what you’ll need to get if you’re taking my courses. Feel free to order them from some other source than the university bookstore. I don’t get a penny from the U bookstore, but I have to confess, the links below do tie into affiliate programs that give me a few pennies in gift certificates to the various online sources.
Freshman biology majors will be taking Biology 1111, Fundamentals of Genetics, Evolution, and Development (FunGenEvoDevo, for short), either in the fall or the spring term. This course is primarily a qualitative introduction to the basic concepts of the scientific method which will also give you an overview of the fields described in the title. It has three textbooks, but two of them are optional.
Science as a Way of Knowing: The Foundations of Modern Biology(amzn/b&n/abe/pwll), by John A. Moore. This is the primary required text for the course; you may be surprised when you read it, since it doesn’t fit the usual expectations of an introductory biology textbook. We did tell you this was a liberal arts university when you enrolled, though, didn’t we?
Life: The Science of Biology(amzn/b&n/abe/pwll), by David Sadava, H. Craig Heller , Gordon H. Orians, William K. Purves, David M. Hillis. This book is optional, but highly recommended, and will be used as a reference text throughout the course. You can get by using the copies in the reference section of the library, but since this book will also be used in our required biodiversity and cell biology courses, you might as well bite the expensive bullet and get a copy now. The links above are to the 8th and latest edition; it’s fine to use the 7th edition.
The Counter-Creationism Handbook(amzn/b&n/abe/pwll), by Mark Isaak. This book is an entirely optional resource; if you’re going to be a biologist, though, you’re going to have to argue with creationists sometime, and this text is invaluable. We will, however, only be using it for about a week, so if it breaks your budget, feel free to share another student’s copy.
I’ll also be teaching Genetics, Biology 4312.
It all sounds so fun, doesn’t it?
I’m giving my students a take-home exam tomorrow, and one of the questions references this paper:
Stoleru D, Peng Y, Agosta J, Rosbash M (2004) Coupled oscillators control morning and evening locomotor behaviour of Drosophila. Nature 431:862-868.
I’m just providing the link here to simplify finding the paper — if you aren’t in my neuro class, you can ignore this.
American River College has, as most colleges do, a student body organization that is elected by the students. They recently had their elections, and got a bit of a surprise: the right-wing Christian group had organized, appealed to the student on the basis of their shared religious beliefs, and swept the election. It also helped that they could call on ethnic identities — Sacramento apparently has had an influx of Slavic immigrants with an odd(er) and often rather nasty form of the Christian cult. These are the Slavic Christian groups that are hysterically homophobic—it’s evident on their club forum, too.
EVERYWHERE I LOOK, ON TV IN SCHOOL EVERYWHERE BUT IN CHURCH ALL I SEE IS GAY THIS, GAY RIGHTS THAT OPEN DISPLAYS OF THIER LIFESTYLE BEING PUSHED DOWN OUR THROATS, I KNOW THAT JESUS LOVES THE SINNER BUT HATES THE SIN, IT JUST APEARS THAT, THAT SIN IS BEING THRUST UPON US IS THERE NOTHING THAT CAN BE DONE, IS THIS WHAT WE HAVE TO LOOK FORWARD TO, SODOMITES RUNNING AROUND, OPENLY PROMOTING THIER LIFESTYLE, GAY MARRIAGE, GAY PASTORS, GAY CHURCHES, ITS LIKE GETTING OUT OF CONTROL, AND ITS VERY SAD TO SEE THIS DAY COME TO LIGHT, AND THERE IS NOTHING WE CAN DO ABOUT IT.
THATS THE SADDEST THING EVER
They also seem to have a deep-rooted aversion to the period. And isn’t that just the cutest little example of suppressed homosexuality ever? All the pushing down throats and thrusting, and the poor little ranter is just so helpless.
Anyway, they organized and they got elected, which is fair enough. It’s still worrisome that people can be so easily manipulated by a candidate who is clearly batshit insane, but just the religious testimonial is enough to sway them. It’s what I dread about American elections in general: they are dominated by looney appeals to religious nonsense, and rational choice does not seem to come into it.
Of course, the fortunate thing about this petty coup is that, well, student organizations have some power to manage internal affairs, but don’t really have much say in the larger picture of running the college. This sentiment is absurdly impractical:
The other former member club member elected to the Student Association, Dennis Choban, listed his goals on his Student Association application form. They included “removing humanistic bias from certain courses (such as evolution science), and encouraging live discussion of nontraditional views in all classes.”
Student group leaders know that what is involved is largely sitting in meetings and managing paperwork that gets financial support from the administration flowing to campus organizations. If they go into this expecting to be able to purge gays, liberals, and evilutionists from the faculty, boy, are they ever going to be disappointed. And then there’ll be the laughing in their faces and the wasted effort and the growing sense of futility. But who knows, they seem to be repressed bottoms, they might like it.
Dear students of Biol 4003: Neurobiology—
EXTRA CREDIT? You haven’t even turned in your final lab reports, and you’re already asking for extra credit? This speaks of a serious lack of confidence, and I don’t know that I should pander to your low self-esteem. Tell me instead that your work on the final exam and the last lab report will dazzle me so much that giving you a mere “A” will be insufficient, and I’ll have to come to your homes and clean your house to make up the difference.
Besides, didn’t anyone ever tell you that a cluttered lab is an active, happy lab?
And that tank with the yellowish water in it is actually a dilute bleach solution that I use for sterilizing. It is true that I should flush that and replace it with a fresh solution, though.
So maybe there is a place for having a lab clean-up day. I could make meticulousness part of the lab grade, and dock you all 10% of your score if the lab is in a less than sparkling state at the end of the term. Yeah, that’s what an evil professor should do … I’ll have to think about it.
What is wrong with the teachers in New Hampshire? They just endorsed Clinton for the Democratic candidate, and Huckabee for the Republicans. Huckabee is a deranged young earth creationist! Did the NEA just spit in the face of its science teachers? How could they possibly support a creationist?
Huckabee, a former Arkansas governor, was the only Republican candidate to speak at the national NEA meeting in Philadelphia in July. His campaign also courted the New Hampshire chapter, and he was the only GOP candidate to meet with chapter officials, a source with the New Hampshire union said.
Oh. The NH NEA can be bought for cheap: just show up.
Well… it’s about that time. You know, the end of the semester where you start every project you’ve had the semester to complete. At least that’s what I’m doing. I finally made some headway on my Neuro project during the past few weeks. I’m sleep depriving zebrafish; I had planned to devise a scheme using streams of bubbles that work on some obnoxious structure to generate a regular disturbance (alright it was PZ’s idea). However I finally admitted defeat about the same time I shattered a water heater and realized I had gotten nowhere.
Desperately I went to a local farm supply store to look for what I could only articulate as “a really really slow motor.” (I don’t want to hear any comments about torque or gears… A: I probably won’t understand you and B: at this point in the semester, it might make me weep.) I tottered over to what looked like the motor isle… although they could have been bombs or anchors because I wouldn’t have known the difference. I waited until my confused expression attracted an employee and asked if they had any of those “really really slow motors… to… um… turn a rod in my fish aquarium.” The guy actually looked offended like I asked for adult entertainment products. “We wouldn’t sell any of that here.” He replied stiffly. Fortunately his buddy overheard and offered, “You mean like a rotisserie?”
Brilliant! They tried to sell me a one hundred dollar rotisserie which I declined, but the idea was invaluable. Why didn’t I think of that? I was imagining a Rube Goldberg machine with a lot of hot glue. Anyway I found an old rotisserie motor for $5 and am quite pleased. Also, PZ put together a big black box in which I’ll hang a light on a timer. Not only will these fish be gently stirred but they’ll have the lights going on and off all night.
I would feel bad except I’m not sleeping either.
Today in class we learned about the functioning of olfactory nerves. It was really quite interesting, especially to find out how the olfactory system is organized. Let’s begin in the nasal cavity. Here, present in the mucus layer, are projections of the olfactory receptor cells. Each receptor cell is only capable of binding to one specific type of odorant molecule. These receptor cells travel through the porous bone separating the skull from the nasal cavity, and feed into a specific glomerulus. Glomeruli are located in the olfactory bulb, and have multiple receptors feeding into them. However, each glomerulus receives input from only one receptor type. In the glomerulus, the receptor neurons make excitatory connections with other cells, whose own axons project into the olfactory cortex in the brain. What is cool here is that there are about 1000 different types of olfactory receptor neurons, which each have their own proteins. This means that there are most likely 1000-2000 genes encoding for olfaction. It has been shown that this is not a combinatorial system like that developed for immunity.
Another cool thing I learned was that every time someone blows their nose, they are losing part of their brain. Seriously though, it’s not quite as bad as it sounds. What is really happening is that you are losing the olfactory receptor cells that protrude out into the mucus layer inside the nasal cavity. The neat thing is that these cells are able to regenerate, which is unusual for other human neural cells. I was wondering, if perhaps, due to the organization of the olfactory nerves, regeneration is able to happen because of the interaction between the olfactory receptor neurons and the glomeruli. Perhaps the protruding parts of the cells are able to be regenerated because they are actually only part of the cell, not the entire cell. If this is true, then if the glomerulus were destroyed, would that permanently destroy the sense of smell? Or would the glomerulus be capable of regeneration, like the olfactory receptor cells that feed into it?
