Cover: Polished slice through a rock showing layers of a fossilized stromatolite. Each layer began as a covering of bluegreen algae (cyanobacteria), which captured grains of sediment and became mineralized. Over time layers accumulate to form a stromatolite, or rocky mound. Fossilized stromatolites as old as 3.5 billion years have been found, making them the oldest fossilized remains of life on Earth (see p. 75). (Image © Dirk Wiersma/Photo Researchers, Inc.)

Imaging—and Imagining—Immune Responses to Infections
After Antonie van Leeuwenhoek viewed “animalcules” from the human oral mucosa during the 17th century, microscopy became an increasingly important tool for diagnosing infectious diseases and following host responses. Microscopy continues to advance technically, even during the past few years. For...

Adaptive Laboratory Evolution
We now can observe evolution in laboratory experiments, define its dynamics, and determine the genetic changes underlying new phenotypes. What happens in such experiments may not be directly applicable to evolution in natural habitats, however, unless particular habitats can be accurately reprodu...

The Deep History of Life
The view down Lake Louise is easily one of North America's finest, with towering peaks framing crystalline blue waters. Standing along the lakeshore, I sense the same majesty as other hikers, but I also see something else—something equally grand, but in a different way. Our planet records it...
