Latest buzz in research: Intoxicated honey bees may clue scientists into drunken human behavior
... We may be able to examine how ethanol affects the neural
basis of aggression in this insect, and in turn learn how it affects humans." Mustard and Wright conducted this research with Ohio State colleagues Brian Smith, a professor of entomology, and Ian Maze, an undergraduate student studying microbiology....
