The disinfectant powder is stirred in bacteria-contaminated water (upper left). The mixture is exposed to sunlight, which rapidly kills all the bacteria (upper right). A magnet collects the metallic powder after disinfection (lower right). The powder is then reloaded into another beaker of contaminated water, and the disinfection process is repeated (lower left).

Graphical abstract. Credit: Nanomaterials (2023). DOI: 10.3390/nano13081404 Topics: Biology, Environment, Nanomaterials, Nanotechnology Among the biggest environmental problems of our time, micro- and nanoplastic particles (MNPs) can enter the body in various ways, including through food. And now, for the first time, research conducted at MedUni Vienna has shown how these minute particles manage to breach the blood-brainContinue reading “Mice, Men, and Nanoparticles…”

Topics: Civilization, Climate Change, Environment, Existentialism, Global Warming Everything about Earth and the organization of human civilization is about the control of resources. We’ve come up with arbitrary “rules” about who is worthy of those resources, and how much they can horde, or obtain. Pharaohs, priests, secret societies, and guilds all have “knowledge” they jealouslyContinue reading “Himalayas…”
