1.  In a new study, adult rats exposed to 65 dB sound — roughly the upper level of normal human speech volume — for 10 hours daily, after 2 months did not perform as well on listening tests and had fewer nerve cells that are involved in detecting sound. It suggests that the brain was altered by the sound conditioning. [Remember those Maaban tribes with their perfect hearing in old age...] Science News 16Jn12

2.  French Researchers have developed "midprice" wallpaper that would block cellular and WiFi signals while letting through AM/FM waves and emergency transmissions. Developed by engineers at the Grenoble Institute of Technology and the Centre Technique du Papier--and making use of a conductive ink containing silver particles (a passive block, not a jamming system)--the wallpaper will be marketed to people concerned about outsiders' snooping on their private networks as well as those who, for perceived health reasons, simply want to shield themselves from as many electromagnetic waves as possible.
