Silicon Second Nature takes us on an expedition into an extraordinary world where nature is made of bits and bytes and life is born from sequences of zeroes and ones. Artificial Life is the brainchild of scientists who view self-replicating computer programssuch as computer virusesas new forms of life. Anthropologist Stefan Helmreich's look at the social and simulated worlds of Artificial Lifeprimarily at the Santa Fe Institute, a well-known center for studies in the sciences of complexityintroduces readers to the people and programs connected with this unusual hybrid of computer...

Alien Ocean immerses readers in worlds being newly explored by marine biologists, worlds usually out of sight and reach: the deep sea, the microscopic realm, and oceans beyond national boundaries. Working alongside scientists at sea and in labs in Monterey Bay, Hawai'i, the Woods Hole Oceanographic Institution, and the Sargasso Sea and at undersea volcanoes in the eastern Pacific, Stefan Helmreich charts how revolutions in genomics, bioinformatics, and remote sensing have pressed marine biologists to see the sea as animated by its smallest inhabitants: marine microbes. Thriving in...
