Bacteria that live in the digestive tracts of animals may influence the adaptive trajectories of their hosts.

NEXT STEP: The virtual center "is the natural evolution of our shared research interests," says Ashley T. Haase, chair of the microbiology department at the University of Minnesota. When AIDS researchers physically located in four different states hold a meeting, it almost feels like they're sitting at a table across from each other--but they're really just facing their individual computer screens. They view slides of the human immunodeficiency virus in lymphoid tissue in real time and discuss

Wishing you a sciency season’s greetings!

Researchers develop a CRISPR-based, two-phage system that sensitizes resistant bacteria to antibiotics and selectively kills any remaining drug-resistant bugs.

Editor's Note: This is the first of two articles on questions raised by recent stem cell discoveries. The second article, focusing on various organs and the nervous system, will appear in the Nov. 27 issue of The Scientist. Researchers first isolated embryonic stem cells (ESCs) from mouse blastocysts almost 20 years ago, and a paper announcing the discovery of human ESCs emerged in 1998. Adult-derived stem cells (ASCs) have since become the rage in certain quarters of biology, with unexpected--

Editor's Note: On May 2, the National Academy of Sciences announced the election of 60 new members and 15 foreign associates from nine countries in recognition of their distinguished and continuing achievements in original research. Nearly half of the new members are life scientists. In this article, The Scientist presents photographs of some of the new members and comments from a few of them on their careers and on past and current research. A full directory of NAS members can be found online a
