Life sciences writer Susan Milius has been writing about botany, zoology and ecology for Science News since the last millennium. She worked at diverse publications before breaking into science writing and editing. After stints on the staffs of The Scientist, Science, International Wildlife and United Press International, she joined Science News. Three of Susan's articles have been selected to appear in editions of The Best American Science Writing.
