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.

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).
