Chris Hedges is a Pulitzer Prize-winning journalist who has worked for many years at the New York Times, NPR, and several other publications. In his sermon he expounds on the long-standing problem of speaking truth to power.

A new genomic study has now found that he didn't look the way previous studies had imagined him - instead he was bald, his skin was darker, and he had an ancestry that was far more exotic and isolated than previously thought.In September 1991, two hikers discovered a human body in the Alps near the Austria and Italy border. At first they assumed they'd stumbled on an unlucky modern mountaineer, but on closer, scientific investigation, it was determined that the chap had died about 5,300 years ago. In the three decades since his discovery, Otzi has been studied extensively, with scientists able to figure out what he ate, how he dressed, how he lived and how he died.His full genome was published in 2012, allowing scientists to reconstruct an image of what he might have looked like. From that data, Otzi was imagined as a fairly light-skinned man with a bushy beard, a thick head of unkempt hair, deep-set eyes and wrinkled skin beyond his 45 years of life. But a new study, using more comprehensive genomic analysis techniques, upends much of that picture.Previously:

The work is published in the journal EcoMat.

Researchers have now developed a new way of removing the hormone from water, however, using what's known as "smart rust."Developed by scientists at Germany's University of Erlangen-Nuremberg, smart rust takes the form of spherical iron oxide (aka rust) nanoparticles that are covered in phosphonic acid molecules. The molecules protrude from the surface of the spheres like hairs. By binding different compounds to the ends of those hairs, it's possible to make them adsorb different types of waterborne pollutants.The iron oxide particles themselves are superparamagnetic, meaning they're attracted to magnets but not to one another. This quality keeps them from clumping together - so they can be thoroughly mixed into tainted water - while also making it possible to subsequently remove them from that water simply by swirling a magnet through the liquid.[...] Due to the fact that estrogen molecules consist of a large steroid body with a slight negative charge, he coated smart rust particles with two types of molecules. One of these has particularly long "hairs," while the other is positively charged. When combined on the surface of the iron oxide spheres, these molecules form multitudes of estrogen-trapping pockets.When tested on water spiked with estradiol, which is the most potent type of estrogen, the new form of smart rust successfully removed the hormone from that water. Further research will now explore how well the technology works in real-world conditions, and how many times the particles can be reused.Original SubmissionRead more of this story at SoylentNews.
