A peer-reviewed scientific journal is using a different sort of medium to present research — video. The Journal of Visualized Experiments — or JoVE — is an online journal where researchers present their studies as videos, says Technology Review's Conor Myhrvold. Each article consists of a short video that shows all the steps the authors took to complete an experiment, supplemented by text that has been peer reviewed. "JoVE has developed a following in the life sciences," Myhrvold says. "The written supplements to the videos still pass through conventional peer and editorial review. Then an in-house JoVE video production team collaborates with the scientists to create a script that details the necessary steps to re-create the researchers' laboratory techniques." The end result is a 10-minute video with animation and graphics. Some videos are free, but for the most part, JoVE relies on the traditional journal subscription model, Myhrvold adds.
