Smells Like Mouse Spirit

Smellslikemice According to this study, male and female mouse brains are the same. The difference is that female mice can smell certain things that make them less aggressive and more inclined to stop and ask for directions.

"From a developmental standpoint, the finding is very satisfactory," said Catherine Dulac, an HHMI investigator and Harvard University professor of molecular and cellular biology who led the new study. "It means you only have to build one brain in a species and that the one brain is built, more or less, the same in the male and the female."

The Handsome Dr. Brenton Gravely, our staff geneticist, will explain this on the show today.

I like the idea of the Howard Hughes Medical Institute (HHMI). Where the mice don't cut their hair or fingernails.


Well, that explains some things we've been observing at my house. We've had this mouse in the house for months. Laid a( glue ) trap for it under the kitchen sink. One morning we checked the trap. It was gone. Gone! We figured this was one smart mouse. My wife said, " Gotta be a female. " I didn't argue. Just got back from vacation ( Not Disneyland ) and found pretzel debris and empty bottles of Corona on the couch. And lots of droppings. The TV was on. Tuned to the Spike Channel. And there were some videos strewn around the living room ( Mice Gone Wild, Minnie Does Dallas, etc. )

Also found that missing glue trap, under one of the cushions. It was stuck to an old copy of Playboy ( July, 1999 ) I have no idea how that ( The magazine ) got there. Minnie must have found in a neighbor's house and dragged it in. That's my theory. The wife's not buying it.

Terry, that is too funny!!

I have had a mousie for a few weeks now. I haven't seen it, but my husband did for a split second. Every night, Widget (my cat), opens the cabinet under my sink and waits for him to come out. It's not happening.

Clearly, a female mouse indeed.
