Scared snails opt for single parenthood rather than wait for a mate. National Evolutionary Synthesis Center, August 16, 2010. Solitary snails in search of a mate put off parenthood as long as possible in the hopes that a partner will appear. But scared snails settle for single parenthood much sooner than their calm counterparts, says a new study. Picked up by USA Today, the Dallas Morning News, and LiveScience.

Scientists flag possible risks from soy formula. Charlotte Observer, April 26, 2010. Soy formula has been used for decades as an alternative to milk formula for children who are lactose intolerant or whose families wish to maintain a vegan diet. In recent years, however, studies in laboratory animals have raised concerns about the safety of soy.
