Speaking of Mother's Day, I couldn't start the weekend without referencing A Biologist's Mother's Day Song. My colleague wrote about the sweet video, made by a Stanford biology student, last year - but it's worth another look. Others seem to agree: The video has been viewed more than 135,000 times and "liked" by more than 1,200 viewers on YouTube. Enjoy!
