Researchers from Ohio State University have found a way to recycle food waste, specifically eggshells and tomato skin, into car tires, replacing carbon black, a petroleum-based filler used in creating tires.
Burn patterns evident on eggshells belonging to ancient, 500-pound flightless Australian birds were recently found by researchers from the University of Colorado Boulder. This suggests early humans hunted the bird and collected its eggs to cook.
An innovative use of tool-making was recently observed in a captive population of greater vasa parrots. It turns out these resourceful birds make tools to grind seashells into nutritious calcium powder.
