POPSMajor biological discovery…inside the Chernobyl reactor "That is to say, the melanin molecule gets struck by a gamma ray and its chemistry is altered. This is an amazing discovery, no one had even suspected that something like this was possible. Aside from its novelty value, this discovery leads to some interesting speculation and potential research. Humans have melanin molecules in their skin cells, does this mean that humans are getting some of their energy from radiation? This also implies there could be organisms living in space where ionizing radiation is plentiful."

POPSRare Photos Of Isolated Korowai "Tree People" (thanks, openthink) The Korowai have been reported to practice cannibalism as recently as the early 1990s. Anthropologists suspect that cannibalism is no longer practiced by the Korowai. Recent reports suggest that the Korowai people have been coaxed into encouraging tourism by perpetuating the myth that it is still an active practice. A lot of new photos of the tribe: http://www.georgesteinmetz.com/index.php?section=11&page=view_photos

POPSCaral: The first city in the New World A brief article on a stunning archaeological discovery in South America. About six years ago, Peruvian/American archaeologist Ruth Shady , introduced the "oldest city in America" to the world. It was Caral; an ancient city on the Pacific coast of Peru, with trade centers, temples and a pyramid complex not less impressive than its counterparts in Mexico and Guatemala. The most exciting thing about Caral was its age: The city was carbon dated to ca. 3000 BCE, which strongly suggested a radical change in history textbooks. All evidence show Caral was not an exception in the region and there are many more ancient towns, waiting to be discovered. Another interesting thing about Caral is, its surprisingly peaceful social order. Archaeologists found no city walls, no forts, no signs of an army and even not a single weapon in Caral. Once again, thanks to Ruth Shady for this fantastic discovery.

POPSYour life is Perfect. We often don't know if we want something until we get it, and then find it wasn't what we wanted. Through that discovery, we can start to believe we really wanted something else, and the chase continues, turning goals into hurdles. Often confusing improvement with change. Perhaps another angle could be learning what we need to, but also trying to improve what we can already do well, without neglecting the opportunities to learn from what we can consider to be failures. We can change situations, but changing who we are may not be possible, and if it is we don't have the foresight to make it a likely improvement.
