Searching all the porn on the Internet might not seem like the most scientifically productive activity, but computational neuroscientists Ogi Ogas and Sai Gaddam did it anyway.  
 
For their new book, A Billion Wicked Thoughts: What the World's Largest Experiment Reveals about Human Desire, Ogas and Gaddam analyzed the results of 400 million online searches for porn and uncovered some startling insights into what men and women may really want from each other — at least sexually. I spoke recently with Ogas.
