Natural gelatin, extracted from the shiny skin of a seagoing fish called Alaskan pollock, may someday be put to intriguing new biomedical uses, according to an ARS chemist who's developing strong yet pliable sheets, known as films or membranes, that might be made from a blend of gelatin from the fish skins and a bioplastic called polylactic acid that's produced from fermented corn sugar.

ARS researchers have developed more than 100 hemlock hybrids suitable for testing for their tolerance to attacks by the invasive insect known as hemlock woolly adelgid that's devastated native hemlocks in 17 eastern states, killing trees and disrupting natural ecosystems. (11/10)
