Do Human Tears Send a Signal?

Caption

A. To obtain tears, donor women watched sad films in isolation, using a mirror to capture tears into a vial. A typical donation contained ~1 ml. B. For continuous exposure, tears deposited onto a pad allowed ongoing nasal airflow exposure, but not transdermal diffusion. Panels A and B are illustrations. This image relates to an article that appeared in the Jan. 6, 2011, issue of Science Express, published by AAAS. The study, by Dr. Shani Gelstein at the Weizmann Institute of Science Rehovot, Israel, and colleagues was titled, "Human Tears Contain a Chemosignal."
