nose jobs change female mice into sex machines !

When scientists performed “genetic nose jobs” on female mice, they were surprised to find that they’ve turned them critters into insatiable sex machines (i.e. behave like males)!

The new work of the Harvard University and Howard Hughes Medical Institute team, published in the journal Nature, indicates that defects in this organ, known as the vomeronasal organ, lead female mice to act like males, solicting them, mounting them and thrusting them while abandoning nesting and nursing.

"These results are flabbergasting," says Prof Catherine Dulac. "Nobody had imagined that a simple mutation like this could induce females to behave so thoroughly like males."
