Another example of web-based educational site: iBioSeminars was launched by The American Society for Cell Biology and contains seminars on medicine, cell biology and biological mechanisms. All available for download in QuickTime, mp4, iPodVideo or Powerpoint formats. Via ScienceRoll.
iBioSeminars is a freely available library of seminars from outstanding scientists. Our mission is to host lectures that describe on-going research in leading laboratories (they are not basic, survey-style lectures as might be found in undergraduate or graduate student biology courses). However, iBioSeminars features a more extensive introduction into the subject matter than a typical 50 min university seminar. Thus, these lectures are intended to be more accessible than many typical department seminars to advanced undergraduates/beginning graduate students and researchers outside of the specific field.
