Broadening Applicability Fosters Growth In Microbiology's Current Job Market
Marcia Clemmitt | May 16, 1993 | 8 min read
Life scientists are increasingly adopting the belief that microorganisms are virtually everywhere and are responsible for just about everything. This, plus the maturation of molecular- level methods of working with these tiny creatures, is a source of considerable optimism for microbiologists as the 93rd general meeting of the American Society for Microbiology (ASM) convenes in Atlanta this week. What they see, in career terms, is that progress in their field is bound to yield an ever-widening

Stem Cell Discoveries Stir Debate
Douglas Steinberg | Nov 12, 2000 | 9 min read
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--
