    Found in Siberia a multi-functional tool, which can cut whatever you like, (butcher) and process skin, or make other tools: a "Palaeolithic Swiss Army knife" done by 60.000 years ago: . Image: Institute of Archaeology and Ethnography of SBRAS

    This is one of the nearest planetary nebulas: the Helix, 700 lightyears distant. It’s an old loosing its external layers creating a nebula. It is expected our will create a planetary in 5000 million years aprox. Image

    African population have 0.5% of their genome from Neanderthals. The genes have been carried to Africa by a human population that left Africa 100-150000 years ago, interbred with Neanderthals outside of Africa and then returned: . Image: M.Luk Princeton Univ
