Since the 9/11 attacks, no book has provided a satisfactory answer as to WHY the attacks occurred and who was ultimately responsible for carrying them out - until now.
"We took a molecular approach and asked whether any aspects of a pheromonal system are preserved in the human genome," says Peter Mombaerts, of The Rockefeller University in New York. Two years ago, his laboratory identified eight human DNA sequences that share distinct structural elements with mouse pheromone receptors. Seven of the sequences proved not to be functional genes. One sequence, however, encodes a receptor protein found in epithelial tissue in the nasal cavity. The findings appear in the September issue of Nature Genetics.For decades, studies have found physiological evidence of pheromonal effects in humans, most notably the synchronization of menstrual cycles of some women who live together.
