Data!

I hate killing sea monkies.

I know it's for a good cause (research and all) but I hate killing them anyway. I drown them in ethanol and the wriggle and writhe like they're in pain (they probably are, after all). Somehow working as hard as I have just to kill them in the end seems contradictory.

I am so never doing research on living things again. I'm anthropomorphosizing crustaceans, for heaven's sake! It's a good think algae don't have eyes or I'd probably feel sad for killing them, too.

On the plus side, I have data! We're still working on standards for oxygen and hydrogen, so I decided to measure my natural samples for CN. For the amount of work I put into my stable isotopes class I figured I should get at least one potentially useful data set. So, here it is:



Cool, huh?

Apparently, there's a shift in the Nitrogen isotopes of my little brine shrimp somewhere between September and October. Not sure why yet--my current theories are this could be an input of light nitrogen from someplace else making its way into the brine shrimp biomass, or it could be the physiology of the little beasties getting ready for massive cyst production (maybe?).

Death to Sea Monkeys

They've died again. And again... And again.

I think they're telling me something: I shouldn't have a project that involves living things. Ever.

I know this is just a part of grad school--failures make the successes that much sweeter and all, and it's all a part of the learning process. That said, I don't understand why it is I can grow sea monkeys just fine last summer when I wasn't trying to experiment on them and this summer they're dying on me like flies. Little aquatic flies.

This is so irritating.

Maybe they know when I'm going to experiment on them and they all get together after seeing a few of their comrades in arms sacrificed in a shower of ethanol, and decide to commit hari-kiri to avoid the death I plan for them.

I've asked at the pet store how to keep them alive, but most people just hatch the little beasts and then dump them into a fish tank with some veracious, crustacean-eating fish. Argh.

So, it's on to the next set of sea monkeys, with the hope these ones will prove hardier, or the test I set up (this time I'm varying the quantity of food I'm giving them) will turn out to be the last step between me and a successful equilibration experiment.

Here's to hoping.
