It would seem to be something you'd see only in a cartoon or at a Phish concert, but according to park rangers in New South Wales, Australia, dozens of giant, fluorescent pink slugs have been popping up on a mountaintop there. The eight-inch creatures have been spotted only on Mount Kaputar, a 5,000-foot peak in the Nandewar Range in northern New South Wales. Scientists believe the eye-catching organisms are survivors from an era when Australia was home to rainforests. A series of volcanoes, millions of years of erosion and other geological changes “have carved a dramatic landscape at Mount Kaputar”, the park service wrote on its Facebook page, and unique arid conditions spared the slugs from extinction.

The book “Elektroschutz in 132 Bildern” (Electrical Protection in 132 Pictures) was published in Vienna in the early 1900s by a Viennese physician named Stefan Jellinek (1878-1968, a founder of the Electro-Pathological Museum). The pictures are nice and direct and unambiguous; they teach, graphically, that the surest way to kill yourself with electricity is to form a complete path from source (usually the bright red arrow) to ground (the screened back, pink arrow). Arrowheads provide the path for current flow. (Photo by The Vienna Technical Museum)
