    Changing one's diet to lose weight is often difficult. There may be physical and psychological effects that reduce the chances for success. With nearly 65 percent of the adult population currently classified as overweight or obese investigating factors that contribute to dieting failures is an important effort.

  3. Gene in male fish lures females into sex
    11-14-2007 · EurekAlert!
    A gene has been found in male cichlid fish that evolved to lure female fish so that male cichlids can deposit sperm in the females mouths. A study in the online open-access journal BMC Biology reveals that the gene is associated with egg-like markings on the fins of cichlid fishes and uncovers the evolutionary history of these markings, which are central to the success of the fishes' exotic oral mating behavior.

    The success of the “reign” of a honey bee queen appears to be determined to a large degree by the number of times she mates with drone bees. That is what research by scientists in the Department of Entomology and W.M. Keck Center for Behavioral Biology at North Carolina State University suggests. Their research was published Oct. 3 in the online scientific journal PLoS ONE
