Philip Skell's opinion highlights the proximate vs. ultimate causation dichotomy that's so familiar to biology students.

In your August 1, 2005 issue, Herbert Sauro writes: "Given the statistics on modern chip design, one wonders if, in fact, cellular complexity has been surpassed [by computer technology]. For example, with the recent move to 90-nm fabrication technology, the average transistor is now less than 50 nm in diameter – only 5 times bigger than the average intracellular protein."1 However, proteins are not just static structures of atoms; they also contain dynamic circuits that convey nuclear forc

On the morning of September 7, Brian Cass, chief executive of contract research firm Huntingdon Life Sciences, was standing in an anteroom of the New York Stock Exchange (NYSE) chatting to officials, waiting to go onto the floor of the exchange where Huntingdon's US parent company, Life Sciences Research (LSR) was due to be listed.

Human embryonic stem cells appear to accrue genomic changes that could make them unusable therapeutically when cultured at length.

The discovery of even a single case of mad cow disease can be economically devastating.

Researcher Willy Walter of the University of Wisconsin, Madison, has fairly typical gel-documentation needs: "We take pictures of ethidium bromide-stained agarose gels using a UV transilluminator and of yeast colonies under white light."

Last summer got off to a hot start at the June 2005 American Society for Mass Spectrometry meeting in San Antonio, Texas.

A new, single-cell computational model developed by scientists at the University of Chicago and Argonne National Laboratory borrows a technique used in the social sciences to digitally study how random molecular events within a cell influence its behavior.
