Science Videos Search Engine
Rami writes "ScienceHack is a search engine for science videos. What makes ScienceHack unique is that every video is screened by a scientist or an engineer to verify the video's accuracy and quality. ScienceHack focuses on many topics including physics, chemistry and biology. If you go to YouTube to search for videos, you will get spam videos and comments and many conspiracy and low quality videos. ScienceHack has none of that. ScienceHack currently supports videos from YouTube, Google videos and Metacafe."

I suggest videos from Professor Julius Sumner Miller.
Given that Sciencehack is only really aiming to be a Youtube for science, maybe this doesn't really mean very much. Still, a little more openness about the process would have been encouraging.
