Don’t mess with a rat’s testes

Until last Monday, my grade 12 biology class was incomplete. Like lemon meringue pie without the fluffy cream layer. Or a Star Wars movie without a cool, undeveloped and quickly killed-off bad guy. After a rat dissection, my biology class is now finally complete. Cutting up a once-living animal in the name of scalpels and [...]

Until last Monday, my grade 12 biology class was incomplete. Like lemon meringue pie without the fluffy cream layer. Or a Star Wars movie without a cool, undeveloped and quickly killed-off bad guy. After a rat dissection, my biology class is now finally complete.

Cutting up a once-living animal in the name of scalpels and microscopes is kinda like eating a kiwi. As in, you have to forget what that furry outer layer looks like in order to enjoy it. I expected the rat to be a stiff, chemically-preserved board. Instead, it was damp and mooshy. I’m not sure which would be worse.

I assumed the ickiest part of a dissection would be the dissection. I couldn’t have been more wrong. Step one of official dissection procedure is- get this- tying the rat up. Maybe this helps prevent escape attempts and violent zombie-rat uprisings, but either way, once my rat was stretched across the board, each paw tied down to a post, he looked kinda like an Aztec sacrifice.

Or a tiny, furry Christ.

Maybe it was the chemical used to preserve the rat. Maybe it was the fact that dead things tend to stink. Either way, the smell of exposed rat organs is right at the top of the hierarchy of repulsive smells.

After five minutes of poking around, I got used to doing what felt like an invasion of the rat’s body space. It took another 30 seconds to realize that the dry lumpy thingy poking out of its mouth wasn’t a crispy rat tumor: it was it’s tongue.

By the time I reached the rat’s circulatory system, I finally stopped feeling like I was being disrespectful by removing a dead organism’s body parts. Which was right about when I noticed that the group beside me had decapitated their rat.

Beheading an animal that has the potential to be vaguely cute (once it’s been Disney-fied and is sitting in a dimly-lit room) already earned the group some serious psychopath points. But apparently they felt as if the rat hadn’t been mutilated enough. I watched and cringed in horror as they chopped off their rat’s testes.

I had just witnessed the launch of three potential serial killer careers in the making.

When I looked away, refusing to add to the rat’s indignity, I suddenly noticed that I had inadvertently smooshed a pin through one of my own rat’s ears. Had I been alone, I might have wept, then whispered, “I’m so sorry…”

And then maybe found out what a cross section of his tail would look like.

National Biology Competition by U of T: Catnip for Nerds

Not being able to guess at multiple choice is like a Diehard movie without Bruce Willis

After 18 hours, I still haven’t completely recovered.

I never want to see the word, “phenotype,” again. And I still don’t know what the hell Hardy-Weinberg Equilibrium is.

I’m totally shell shocked.

I wrote the University of Toronto National Biology Competition yesterday.

I’m still not actually considering Toronto as a possible university to attend this September. My alter-ego didn’t knock me out, sign up for the test, and then, in the ultimate act of copyright violation, cross the multiverse and destroy all parallel-Scotts, absorbing our collective energy and becoming The One.

I actually signed up for the annual competition because A) I’m a nerd. It’s what we do. And B) All 50 questions were multiple choice. How hard could it be, right?

My ignorance was my downfall.

Multiple choice is easy. Unless A, B, C, D, and E all seem like plausible answers. Take this question, for instance:

Which of the following signal transduction molecules is not bound to the plasma membrane?
A) Cyclic AMP
B) Peptide hormone receptors
C) Adenylyl cyclase
D) Phospholipase C
E) Endo-cyclic Scott-is-screwed triphosphate

Why I’m getting a nose ring

High school dispatch: Survival of the least nerdiest

When my Family Studies class recently had the chance to spend an entire period in the library, I naturally spent the entire hour-and-a-half researching my thesis topic, finding references and working on my position response.

That, and training to become a master at Asteroids.

By grade 12 most students, myself included, gain the ability to not only control a tiny ship as it blows space rocks and aliens to bits, but simultaneously keep track of the librarian’s exact coordinates. Which isn’t so easy, considering a requirement of all school librarians is to be trained in the Ninja arts. You know, so they can sneak up on a student doing anything but schoolwork. Unbeknownst to me, it was already too late.

The librarian had locked on to the weak thermal signal emitted by any student within a 100km radius that’s playing a video game. Before I could switch task bars to the decoy homework website (and regain a carefully-posed bored stupor), the librarian lunged for the kill.

The thing is, I wasn’t even playing Asteroids at that specific moment. I was e-mailing myself all the work I had done. Sure, personal e-mail is a violation of the Library Code of Conduct, but it somehow felt wrong to be caught sending an e-mail when I had been playing a video game 30 seconds before. Sorta like if someone, after robbing a bank and hijacking a car, was caught double parking. I felt like saying, “You think THIS is bad? You should have seen what I was doing 30 seconds ago.”

I had innocently assumed that, since I was surrounded by half a dozen kids talking loudly AND obviously playing video games, I was low on the librarian’s hierarchy of harassment.

I made a grievous error: forgetting to factor in that I am a Nerd.

The basic rule is that the least intimidating-looking student is usually the one that somehow becomes the ‘example.’

Out of a group of students that’s talking loudly, making a mess or playing video games, guess which one becomes the scapegoat:

A) The one that has a biology textbook with them, has glasses, and is fugitively glancing over their shoulder because they’re violating a school library rule,

OR

B) The one that’s slumped low in their chair, has their hair jelled into spikes, is wearing (used-looking) brass knuckles, and is shouting across the aisle, “Hey Bobby, I beat your high score. BOBBY! HEY BOBBY! I SAID I BEAT YOUR HIGH SCORE! WHAT? AN ENTIRE SENTENCE IN CAPITAL LETTERS IS ANNOYING TO READ?”

It didn’t matter that I was working between alien invasions and had the volume at zero. It wouldn’t have mattered if the other kids had decided the time was right to set some books on fire and rip the cover off the biggest most expensive book they could find. I had a biology textbook AND a calculus textbook on the desk beside me. I was doomed. Survival of the least-nerdiest.

By the time I heard the low-frequency “pop” of the librarian phasing directly behind me, I knew it was too late. I only had enough time to formulate a lame excuse. Like, “My thesis evaluates the traditional four-directional steering versus the eight-directional steering found in Asteroids.” Or, “I heard that you could detect a video game, evaluate the relative intimidation-factor of the perpetrator, and recon directly behind them within 0.5 seconds. I just had to see for myself.”

That, or I could shave a large S on the back of my head and get a nose ring.

Extra year of high school? Where’s the victory in that ‘Victory Lap’?

When my biology teacher started talking about a victory lap during class last week, I figured she must be talking about race cars. Or maybe the sound her cat makes when it drinks. But apparently ‘victory lap’ can also be directly translated to, “A grade 12 student that stays behind for an extra year because, [...]

When my biology teacher started talking about a victory lap during class last week, I figured she must be talking about race cars. Or maybe the sound her cat makes when it drinks. But apparently ‘victory lap’ can also be directly translated to, “A grade 12 student that stays behind for an extra year because, well, they can.”

I’m staying open-minded though. I’m sure there are some valid and compelling reasons for staying behind in the public school system for an extra year. I just haven’t figured them out yet. And until then, I admit, I’ll continue to think that willingly staying behind for an extra 200 days of high school is (nearly) the dumbest idea on the planet. Of course, nothing is more dumb than Toby Maguire having been cast as an action hero.

I mean, it’s not like my school offers “Basket Weaving 101” or “Why Star Wars is way Better than Star Trek” courses. You know, to artificially inflate my grade point average to look better on my university applications.

So isn’t calling it a ‘victory lap’ sort of like calling a house with a roof that’s been peeled back by a tornado “open concept” ?
