This book discusses biochemical adaptation to environments from freezing polar oceans to boiling hot springs, and under hydrostatic pressures up to 1,000 times that at sea level. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Life has evolved in an extraordinary way to deal with the most extreme physical and chemical conditions. Extremophilic (extreme-loving) organisms have been found in the superheated waters of deep ocean vents or the hypersaline and cold lakes of Antarctica and indeed often require the extreme conditions of their habitat to survive and thrive. The cellular machinery of extremophiles has developed unique adaptation strategies to effectively function in their given environment. Much scientific attention has focussed on the adaptation of proteins as they have both structural and catalytic functions and hence play key roles in all cellular processes. Moreover, their ability to perform in or withstand extreme physical and chemical conditions has made extremophilic proteins attractive bio-catalysts for a range of industrial and biotechnological applications. This novel and significant book comprehensively summarises our current understanding regarding the structure-function-stability relationship of extremophilic proteins. Leading experts in the field extensively review and comment on the adaptation of proteins to the whole spectrum of physical and chemical extremes. This book represents an important and indispensable reference for students, teachers and researchers with interest or activities in the fascinating area of extremophiles.

As digital technologies are expanding the power and reach of research, they are also raising complex issues. These include complications in ensuring the validity of research data; standards that do not keep pace with the high rate of innovation; restrictions on data sharing that reduce the ability of researchers to verify results and build on previous research; and huge increases in the amount of data being generated, creating severe challenges in preserving that data for long-term use. Ensuring the Integrity, Accessibility, and Stewardship of Research Data in the Digital Age examines the consequences of the changes affecting research data with respect to three issues - integrity, accessibility, and stewardship-and finds a need for a new approach to the design and the management of research projects. The report recommends that all researchers receive appropriate training in the management of research data, and calls on researchers to make all research data, methods, and other information underlying results publicly accessible in a timely manner. The book also sees the stewardship of research data as a critical long-term task for the research enterprise and its stakeholders. Individual researchers, research institutions, research sponsors, professional societies, and journals involved in scientific, engineering, and medical research will find this book an essential guide to the principles affecting research data in the digital age.

I am extremely honored and pleased to have the opportunity to write a few introductory words for this timely volume on Na + /It exchange. This is a field of investigation that I entered into by challenge and necessity, embraced with passion and fmally left in my quest for new discoveries in growth control. Ten years, one third of my scientific life, has been devoted to uncovering the mysteries of intracellular pH (PH;) regulation with respect to growth factor action. I got started on this new topic in 1980, when I heard a rather provocative hypothesis presented by Enrique Rozengurt at an ICN-UCLA Keystone meeting on "Cell Surface and Malignancy". He showed that all mitogens induced amiloride-sensitive Na + entry into resting cells and proposed that, if a compound stimulates Na + influx, it could be a mitogen. In support of his proposal Enrique reported that the amphipathic polypeptide, mellitin, which induced Na+ influx, was indeed mitogenic for 3T3 cells. This was only correlation at this stage. However, I was fascinated by this talk. I immediately approached Enrique to inform him of my skepticism about this beautiful story, and to indicate that I would only be convinced when I succeeded in isolating mutant fibroblasts lacking the amiloride-sensitive Na+ transporter. ''Good luck!" was his response.

This book constitutes the refereed proceedings of the 6th International Workshop on Internet Charging and QoS Technologies, ICQT 2009, held in Aachen, Germany, in May 2009 collocated with the IFIP Networking 2009 conference. The 9 revised full papers presented together with the extended abstract of a keynote paper were carefully reviewed and selected from a total of 26 submissions. The papers are organized in topical sections on competition models, pricing mechanisms, and economics of inter-domain traffic. Bringing together researchers from the area of technology and economy in both industry and academia to discuss key improvements and to support further progress in these fields, ICQT 2009 features combination of micro-economic models, auctions, game theoretic approaches, peer-to-peer, and IMS-based charging.

Physical Biology of the Cell is a textbook for a first course in physical biology or biophysics for undergraduate or graduate students. It maps the huge and complex landscape of cell and molecular biology from the distinct perspective of physical biology. As a key organizing principle, the proximity of topics is based on the physical concepts that

“An engaging, insightful, and challenging call to examine both the rhetoric and reality of innovation and inclusion in science and science policy.” —Daniel R. Morrison, American Journal of Sociology Stem cell research has sparked controversy and heated debate since the first human stem cell line was derived in 1998. Too frequently these debates devolve to simple judgments—good or bad, life-saving medicine or bioethical nightmare, symbol of human ingenuity or our fall from grace—ignoring the people affected. With this book, Ruha Benjamin moves the terms of debate to focus on the shifting relationship between science and society, on the people who benefit—or don’t—from regenerative medicine and what this says about our democratic commitments to an equitable society. People’s Science uncovers the tension between scientific innovation and social equality, taking the reader inside California’s 2004 stem cell initiative, the first of many state referenda on scientific research, to consider the lives it has affected. Benjamin reveals the promise and peril of public participation in science, illuminating issues of race, disability, gender, and socio-economic class that serve to define certain groups as more or less deserving in their political aims and biomedical hopes. Ultimately, Ruha Benjamin argues that without more deliberate consideration about how scientific initiatives can and should reflect a wider array of social concerns, stem cell research—from African Americans’ struggle with sickle cell treatment to the recruitment of women as tissue donors—still risks excluding many. Even as regenerative medicine is described as a participatory science for the people, Benjamin asks us to consider if “the people” ultimately reflects our democratic ideals.
