Life’s most important rendezvous occurs between a sperm and an egg, and scientists have long debated precisely how this get-together occurs.

Now, researchers based in England, China, Taiwan, and the U.S. have identified a sugar, located on a human ovum, that is recognized by human sperm (Science, DOI: 10.1126/science.1207438). The identity of the sugar, called sialyl Lewisx, is an essential piece of information required to unscramble the biochemical steps taken during fertilization and may . . .
