  • A newly discovered behavior, revealed by covert filming, suggests that humans use bodily smells to send signals, much as other mammals do. There is evidence that the scent of women's tears lowers testosterone levels and dampens arousal in men, and that human sweat can transmit fear. Noam Sobel and his colleagues at the Weizmann Institute of Science in Rehovot, Israel, turned to one of the most common ways people touch each other: shaking hands. To find out if people really do smell their hands, his team surreptiously filmed 153 volunteers.
