Two recent blog posts discuss science onscreen. If you didn't read Nature's cover article last week about the forces generated by barefoot runners, you can catch the latest film at Nature Video on the Great Beyond, a clip by the Barefoot Professor (http://go.nature.com/tPTQlH).

In it, Daniel Lieberman of Harvard University in Cambridge, Massachusetts, explains why humans probably evolved to run in a style whereby they land first on the front of their foot — a style favoured by the shoeless. He also demonstrates the method, running cheerily through the snowy streets of Cambridge without his trainers.

Meanwhile, on the Spoonful of Medicine blog, Nature Medicine editorial intern Christian Torres reviews the Hollywood movie Extraordinary Measures (http://go.nature.com/oDUEpM). The film depicts the true story of a father's quest to save his children from Pompe disease — a fatal muscle disorder.

But, as Torres notes, “the film oversimplifies the story by making industry the villain. [It] also glosses over the intricacies of ... conflicts of interest and the clinical trials process, in favor of an emotional response”.
