Catherine Thimmesh’s inspiring look at the role of women in American politics—past, present, and future—is now available with updated sections on Hillary Rodham Clinton, Condoleezza Rice, and Nancy Pelosi. From the time our government was being formed, women have fought their way from behind the scenes to the center of power and decision making. So, why not a woman in the White House? Two thousand eight may be the year!

They study the night sky, watch chimpanzees in the wild, search the beach for rare fossils, and wander into dark caves. And as they explore, they become discoverers. Young and old, they are women and girls who discover the origins of counting and writing, Stone Age cave art, mysterious matter in the universe, and how a puddle of water can be sanitized when heated by the sun.

Illustrated in full color throughout with stunning compuer-generated artwork and with rare paleo photography, this story of scientific sleuthing invites us to wonder what our ancestors were like. From the discovery of Lucy's bones in Hadar, Ethiopia, to the process of recovering and interpreting them (a multidisciplinary approach with contributions from paleontologists, paleoanthropologists, archeologists, geologists and geochronologists), this book shows how a pile of 47 bones led scientists to discover a new -- and, at 3.2 million years old, a very very old -- species of hominid, ancestral to humans.

Scientists involved include: James Aronson, geochronologist at Dartmouth, NH John Gurche, paleoartist at Cornell, NY Donald Johansen, scientist at Institue of Human Origins at Arizona State University Owen Lovejoy, biological anthropologist at Kent State, Ohio Dirk Van Tuerenhout at Houston's Museum of Natural Science, Texas.
