Book Description
The organic chemist is rarely satisfied by a simple "explanation" of the reactivity of organic molecules. Rather, the chemist wants to go one step further, to "control" the behavior of molecules by altering their structure in a controlled way. This is, in fact, a rather stringent definition of "understanding," as it requires the "prediction" of behavior from structure (or structure from behavior). But it also places technical demands on the chemist. He must be able to synthesize the molecules he studies, characterize them at the atomic level of structural resolution, and then measure their behaviors to the precision that his explanation demands. Biological chemistry presents special problems in this regard. Although the tools for synthesis, purification, and structural characterization are now available for manipulating rather large biological macromolecules (proteins and nucleic acids in particular), the theory supporting these manipulations is inadequate. We certainly do not know enough to control generally the behavior of biological macromolecules; still worse, it is not clear that we know enough to design synthetic molecules to expand our understanding about how reactivity in such biological macromolecules might be controlled. Starting from scratch, there are simply too many oligopeptides to make; starting from native proteins, there are simply too many structural mutations that might be introduced.

Book Description
"Through tales of scientific discovery, personal case studies, engaging histories, and careful scrutiny of both the facts and misconceptions behind the headlines, the authors explore the ethical and political challenges presented by the power of this new science. A companion to the acclaimed 8-part PBS television series, their book expands on the issues presented in the series while retaining its accessible style. In an age when science informs the most personal choices in our lives, The Secret of Life prepares readers to act as knowledgeable citizens in debates that demand the widest possible participation."--Jacket.

Book Description
A Harvard biologist and master inventor explores how new biotechnologies will enable us to bring species back from the dead, unlock vast supplies of renewable energy, and extend human life. In Regenesis, George Church and science writer Ed Regis explore the possibilities of the emerging field of synthetic biology. Synthetic biology, in which living organisms are selectively altered by modifying substantial portions of their genomes, allows for the creation of entirely new species of organisms. These technologies-far from the out-of-control nightmare depicted in science fiction-have the power to improve human and animal health, increase our intelligence, enhance our memory, and even extend our life span. A breathtaking look at the potential of this world-changing technology, Regenesis is nothing less than a guide to the future of life.

Book Description
How small can a free-living organism be? On the surface, this question is straightforward-in principle, the smallest cells can be identified and measured. But understanding what factors determine this lower limit, and addressing the host of other questions that follow on from this knowledge, require a fundamental understanding of the chemistry and ecology of cellular life. The recent report of evidence for life in a martian meteorite and the prospect of searching for biological signatures in intelligently chosen samples from Mars and elsewhere bring a new immediacy to such questions. How do we recognize the morphological or chemical remnants of life in rocks deposited 4 billion years ago on another planet? Are the empirical limits on cell size identified by observation on Earth applicable to life wherever it may occur, or is minimum size a function of the particular chemistry of an individual planetary surface? These questions formed the focus of a workshop on the size limits of very small organisms, organized by the Steering .Group for the Workshop on Size Limits of Very Small Microorganisms and held on October 22 and 23, 1998. Eighteen invited panelists, representing fields ranging from cell biology and molecular genetics to paleontology and mineralogy, joined with an almost equal number of other participants in a wide-ranging exploration of minimum cell size and the challenge of interpreting micro- and nano-scale features of sedimentary rocks found on Earth or elsewhere in the solar system. This document contains the proceedings of that workshop. It includes position papers presented by the individual panelists, arranged by panel, along with a summary, for each of the four sessions, of extensive roundtable discussions that involved the panelists as well as other workshop participants.

Book Description
In The Aptamer Handbook, leading scientists from academia as well as biotech and pharma companies introduce the revolutionary concept of designing RNA and DNA oligonucleotides with novel functions by in vitro selection. These functions comprise high affinity binding (aptamers), catalytic activity (ribozymes and deoxyribozymes) or combinations of binding and catalytic properties (aptazymes). Basic concepts and technologies describing in detail how these functional oligonucleotides can be identified are presented. Numerous examples demonstrate the versatility of in vitro selected oligonucleotides. Special emphasis has been put on a section that shows the broad applicability of aptamers, e. g. in target validation, for analytics, or as new therapeutics. This first overview in the field is of prime interest for a broad audience of scientists both in academia and in industry who wish to expand their knowledge on the potential of new oligonucleotide functions and their applications.
