A possible treatment for autism, tail-chasing dogs as a model of human obsessive-compulsive disorder, and what researchers could do with an extra-stretchy version of a material known as a hydrogel are a few of the topics explored in Scientific American's November Advances. Research papers and links to online materials are listed below.

A Shot in the Arm
The U.S. Centers for Disease Control and Prevention has an online guide to vaccines and recommended immunizations.
From Tail Chasing to Hand Washing
Researchers published their findings on canine compulsions in PLoS ONE here.
When not observing sexually promiscuous birds, Mike Webster oversees the largest animal-sound library in the world. To learn more, watch this Scientific American audio-visual slide show.
Break More to Break Less
Zhigang Suo and colleagues describe their new material in Nature. To see the hydrogel stretch to accommodate a falling metal ball (and wobble with the aftershock) watch a video posted by Nature News.
Helpless by Design
Scientific American discussed helpless human babies in the staff's Observations blog. Holly Dunsworth and her colleagues published their findings in Proceedings of the National Academy of Sciences USA (behind a paywall).
