    Gene Silencing by MicroRNAs – Katharina Petsche (2015)

    Welcome to another post of Molecular Nature series highlighting a gene silencing mechanism known as RNA interference. The animation was produced by Katharina Petsche. The discovery was made by Craig Mello and Andrew Fire who shared 2006 Nobel Prize in Physiology and Medicine. Please keep in mind that this video is quite advanced in content and assumes the viewers know about basic molecular biological concepts such as the Central Dogma of Biology. RNA interference (RNAi) is a process used by […]

    48 Cantones: The Mayan Forest – Thomas & Julian Moll-Rocek (2014)

    In their documentary, Thomas & Julian Moll-Rocek explore the Mayan Cosmovision. For Meso-Americans this is a worldview that integrates the structure of space and rhythms of time into a unified whole. In Guatemala’s western mountains, in the state of Totonicapán, a large community forest has prospered for centuries adjacent to densely populated valleys. The Mayan forest cover the hills and the mountain ridge. The management of local resources by the Mayan community provides a counter-argument for the ‘tragedy of the […]

    Development of a Salamander Embryo – Yale University Department of Anatomy (1920s)

    Everyone of us started life from one single cell formed by the fusion of an egg and a sperm. That single cell gave rise to every structure in our bodies. How did that happen? Salamanders are known to be able to regenerate limbs while frogs and lizards cannot. How and why? The time lapsed footage of salamander embryos developing from single fertilized eggs forms the basis of our morphological understanding of animal development. The footage recorded by Yale University researchers […]
