About

The internet is wide and chock full of video content. Scattered throughout this landscape are programs, shows, movies, documentaries and more that are of interest to, about, or otherwise for skeptics, rationalists, freethinkers and other science minded people. The goal of the project is to collect as much of that content into one place as possible. Hoping to make it easier to find programs which might appeal but were otherwise unknown or hard to find.

If there are any freely available programs or shows which you know of that I missed, please let me know about them.

Stomach Bacteria Show Early Human Travels

Evolutionary scientists are increasingly turning to an unusual tool to explore ancient human history: bacteria. Some microorganisms, like Helicobacter pylori, take up residence in our stomachs. Since they go where humans go—and undergo genetic changes along the way—they provide a way to track ancient human migration patterns. A study by a team of international researchers, recently published in the journal Science, shows how genetic investigation of H. pylori in modern-day East Asian and Pacific people has cleared up questions about how that region of the world was first settled.
