The shrimp that went into the light
I was listening to one of my podcasts today. A fresh episode of The Naked Scientists. I don't know whether or not they're actually naked, but most scientists probably wouldn't look all that good naked, so that might be just as well. Anyway, I learned something new. It would seem that when we (and when I say we, I don't mean me) gobble down a prozac or something like that, it’s not all absorbed into the body. Rather, it comes out with the nr1's and the nr2's and makes it's cheerful way down the sewage system and out to sea.
Where it's eaten by crustaceans which then decide to swim out of their murky ocean depths, towards the sunlight. These are undoubtedly more interesting surroundings to an upbeat, high-on-life shrimp, but it also makes the poor bastard more likely to end it's days in the belly of a hungry fish or seabird. Scientists now fear that this sort of thing can have a profound effect on aquatic ecosystems.
I guess the upside to the story is that the crustaceans die happy.
