An anonymous reader writes: Scientists sometimes cry foul when they can't reproduce an experiment that was performed in someone else's lab. Moshe Pritsker and Nikita Bernstein have created JoVE, the Journal of Visualized Experiments to solve that problem. Their website is a lot like YouTube. It allows biologists to share how to videos of their research procedures. This is meant to increase the transparency and reproducability of complicated experiments. Perhaps the best example of this is a video that shows a Harvard Student explaining how to culture stem cells. The Wired Science blog points out that it is very hard to follow written instructions for experiments as complicated as cloning or harvesting stem cells. With a video to guide them, researchers will find it much easier to perform these difficult procedures for the first time.
