The so-called "biometric-Mendelian controversy" has received much attention from science studies scholars. This paper focuses on one scientist involved in this debate, Arthur Dukinfield Darbishire, who performed a series of hybridization experiments with mice beginning in 1901. Previous historical work on Darbishire's experiments and his later attempt to reconcile Mendelian and biometric views describe Darbishire as eventually being "converted" to Mendelism. I provide a new analysis of this episode in the context of Darbishire's experimental results, his underlying epistemology, and his influence on the broader debate surrounding the rediscovery and acceptance of Mendelism. I investigate various historiographical issues raised by this episode in order to reflect on the idea of "conversion" to a scientific theory. Darbishire was an influential figure who resisted strong forces compelling him to convert prematurely due to his requirements that the new theory account for particularly important anomalous facts and answer the most pressing questions in the field.

This article unpacks a particular use of ‘cases’ within developmental biology, namely as a means of describing the typical or canonical patterns of phenomena. The article explores how certain cases have come to be established within the field and argues that although they were initially selected for reasons of convenience or ease of experimental manipulation, these cases come to serve as key reference points within the field because of the epistemological structures imposed on them by the scientists using them and, hence, become usable in a wider variety of circumstances including future theory development.

Debates continue to surround the system in the United States for allocating transplantable cadaveric organs, due in large part to the scarcity of such organs in relation to the number of individuals waiting to undergo transplantation. Candidates awaiting transplantation gain access to cadaveric organs by being placed by individual transplant programs on the national list of the Organ Procurement and Transplantation Network, overseen by the United Network for Organ Sharing. In recent years, the UNOS board has visited the issue of multiple listing, that is, allowing one candidate to be registered on the waiting lists of two or more transplant programs, and has continued to permit multiple listing

In an article somewhat ironically entitled “Disambiguating Clinical Intentions,” Lynn Jansen promotes an idea that should be bewildering to anyone familiar with the literature on the intention/foresight distinction. According to Jansen, “intention” has two commonsense meanings, one of which is equivalent to “foresight.” Consequently, questions about intention are “infected” with ambiguity—people cannot tell what they mean and do not know how to answer them. This hypothesis is unsupported by evidence, but Jansen states it as if it were accepted fact. In this reply, we make explicit the multiple misrepresentations she has employed to make her hypothesis seem plausible. We also point out the ways in which it defies common sense. In particular, Jansen applies her thesis only to recent empirical research on the intentions of doctors, totally ignoring the widespread confusion that her assertion would imply in everyday life, in law, and indeed in religious and philosophical writings concerning the intention/foresight distinction and the Principle of Double Effect

Calls for the “translation” of research from bench to bedside are increasingly demanding. What is translation, and why does it matter? We sketch the recent history of outcome-oriented translational research in the United States, with a particular focus on the Roadmap Initiative of the National Institutes of Health (Bethesda, MD). Our main example of contemporary translational research is stem cell research, which has superseded genomics as the translational object of choice. We explore the nature of and obstacles to translational research and assess the ethical and biomedical challenges of embracing a translational ethos.

This study focuses on the concept of a 'model organism' in the biomedical sciences through an historical and philosophical examination of research with the nematode Caenorhabditis elegans. I explore the choice of C. elegans in the mid-1960s, showing a rich context existed within which the organism was selected as the focus for a molecular biological research program, including an experimental life prior to Sydney Brenner's work. I argue that this choice can be seen as an obvious outcome of what was a complex search procedure, and that the success of the 'worm project' depended not only on organismal choice but also on the conceptual and institutional framework at the Laboratory of Molecular Biology in Cambridge within which it was pursued. Examination of C. elegans work in the late 1960s through the early 1980s illuminates several additional theses. Although development and behavior were the general areas of interest for the project, the original goals and proposed methodology were extremely vague. As the project evolved, which investigations proved to be tractable using the worm depended not only on which methodologies were fruitful but also on the interests and skills of early workers. Much of the power of C. elegans as a model organism can be traced historically to the investment of resources which resulted in an unprecedented, complete description of the organism, and represented a return to a more naturalistic biological tradition. In light of the historical study, I develop a philosophical analysis of C. elegans as a model organism through exploration of the three kinds of modeling with the worm: modeling of structures, processes, and information. I expand the notion of a descriptive model, arguing that C. elegans is best understood as a prototype of the metazoa, and that C. elegans as a model organism has been not only heuristically valuable, but also essential to this research project particularly in its pre-explanatory stages. I conclude by suggesting that more investigation of descriptive prototypes such as those in the worm project must be done to capture important aspects of the biomedical sciences that will be neglected if explanatory models are the sole focus in the philosophy of science
