Weird study I just saw today on SALON, basically showing that shrimp exposed to the main chemical in Prozac are more vulnerable to dying, for whatever reason. Several things about this -- I've been wondering for years about the role antidepressants play in suicides and murder-suicides, but the prospect of the chemical poisoning the environment by the way of urban runoff is creepy as well. The tip of the hat to brain parasites manipulating serotonin levels in shrimp is, of course, intriguing, too, given my lingering fascination with parasites. Parasites are tricky mofos. I'm forever amazed that dinosaurs had tapeworms, and those frickin' tapeworms survived the extinction of dinosaurs and migrated to mammalian species (no doubt because early mammals scavenged dinosaur remains and picked up the tapeworms, which then adapted themselves to mammalian bodies). That's an impressive (and horrifying) evolutionary feat. Don't underestimate parasites! Seriously. They. Will. Fuck. You. Up.
I've also long followed endocrine disruptors in the environment, too, which seem to come from plastics, creating false estrogens which may increase risks of cancer (and may be responsible for declining fertility in populations). Creepy shit.
