The Gates of Immortality
Yves Barral | Oct 1, 2010 | 10+ min read
By Yves Barral The Gates of Immortality Did biology evolve a way to protect offspring from the ravages of aging by creating a physical barrier that separates the parent from its young? Dr. Stanley Flegler, Visuals Unlimited he idea that every organism must age was a concept that surprised many biologists. For a long time, aging was thought to be a process occurring only in multicellular organisms. The reason for this arguably odd presumption was that we knew so

Biotech's new invaluable tool
Jef Akst | Sep 15, 2010 | 4 min read
In just two decades, the protein equivalent of an intron has carved out a significant niche in biotechnology -- and captured the interest of evolutionary biologists, who suspect these potentially ancient elements could provide clues to early enzymes. Image: Wikimedia commonsWith the ability to splice themselves out of proteins and paste the two loose ends of the protein back together, inteins are proving to be an invaluable tool in biotechnology. Just 20 years since their discovery, inteins are
Mapping Subtelomeres
Ricki Lewis | Oct 14, 2001 | 4 min read
In genetics, certain terms sometimes mask what scientists do not yet understand, such as "junk DNA." Similarly, the chromosomal regions just proximal to the tips--the subtelomeres--have been dubbed "buffers," ill-defined DNA sequences that somehow support the telomeres, which control the cell cycle and cellular aging. A team of researchers from the Wistar Institute in Philadelphia, the University of California, Irvine, and John Radcliffe Hospital in Oxford, UK, has used single-copy sequences in
Surpassing the Law of Averages
Jeffrey M. Perkel | Sep 1, 2009 | 7 min read
By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo

First Person | David Botstein Courtesy of Frank Wojciechowski At the age of 60, David Botstein, microarray and genetics pioneer, is learning to play the cello. As a young man, Botstein seriously considered being a musician, but he knew the talent just wasn't there. "I did play the violin, badly," he admits. Yet his love of music is so ingrained--his brother, Leon, is music director for the American Symphony Orchestra--that even as an undergraduate at Harvard, he "ran with the musicians."
60 Members Elected to NAS
Barry Palevitz | Jun 25, 2000 | 6 min read
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
