Access Denied! 18 Places Google Maps Won’t Let You See [Google Maps]

Google has always tried to keep a very open policy with the general public, but it can't always be entirely forthcoming, as is the case with Google Maps. Google has very little say in what gets censored and what doesn't, be it for personal privacy or national security. Finding censored objects on Google Maps isn't the easiest task, as most look like imaging anomalies, rather than some big black bar with "CENSORED" written in large text. More »


Zweite Fragebogenaktion zu Taetigkeiten mit Nanomaterialien in Deutschland

Die Bundesanstalt fuer Arbeitsschutz und Arbeitsmedizin (BAuA) unter Mitwirkung des Verbandes der chemischen Industrie (VCI), des Bundesverbandes der Deutschen Industrie e. V. (BDI) und des Bundesministeriums fuer Bildung und Forschung (BMBF) startet eine zweite Fragebogenaktion zu Taetigkeiten mit Nanomaterialien in Deutschland. Ein pragmatischer Ansatz fuer eine offene Risikokommunikation steht dabei im Mittelpunkt.

What’s the environmental footprint of your nanosilver T-shirt?

Several manufacturers are incorporating nano-sized particles of silver into, among other things, garments like socks and shirts to kill bacteria that cause odor. But does the silver stay in the socks or T-shirts? And what happens to it if it washes out? Also, what is the climate footprint of producing the required nanosilver? To answer these questions, a group of researchers have performed a cradle-to-grave life cycle assessment to compare nanosilver T-shirts with conventional T-shirts with and without biocidal treatment. For their assessment, the team used conventional T-shirts treated with triclosan, a commonly applied biocide to prevent textiles from emitting undesirable odors. The results show significant differences in environmental burdens between nanoparticle production technologies.
