New challenges for Life Sciences flight project management.

Scientists have conducted studies involving human spaceflight crews for over three decades. These studies have progressed from simple observations before and after each flight to sophisticated experiments during flights of several weeks up to several months. The findings from these experiments are available in the scientific literature. Management of these flight experiments has grown into a system fashioned from the Apollo Program style, focusing on budgeting, scheduling and allocation of human and material resources. While these areas remain important to the future, the International Space Station (ISS) requires that the Life Sciences spaceflight experiments expand the existing project management methodology. The use of telescience with state-the-art information technology and the multi-national crews and investigators challenges the former management processes. Actually conducting experiments on board the ISS will be an enormous undertaking and International Agreements and Working Groups will be essential in giving guidance to the flight project management Teams forged in this matrix environment must be competent to make decisions and qualified to work with the array of engineers, scientists, and the spaceflight crews. In order to undertake this complex task, data systems not previously used for these purposes must be adapted so that the investigators and the project management personnel can all share in important information as soon as it is available. The utilization of telescience and distributed experiment operations will allow the investigator to remain involved in their experiment as well as to understand the numerous issues faced by other elements of the program The complexity in formation and management of project teams will be a new kind of challenge for international science programs. Meeting that challenge is essential to assure success of the International Space Station as a laboratory in space.

Marcello Malpighi and the difficult birth of modern life sciences.

All his life, Marcello Malpighi (1628-1694), the founder of modern microscopic anatomy, was unwillingly involved in difficult debates within a reactionary medical milieu that questioned the significance of modern science and its utility to medicine. Malpighi's responses to his detractors, included in posthumous works first published in 1697 by the Royal Society, offer an important insight into a critical phase of scientific progress in the 17th century and help to reveal the prevailing conception of science. In some ways, Malpighi's views predate important ideas in modern biology.

Molecular profiling of single cells and tissue specimens with quantum dots.

Quantum dots are tiny light-emitting particles on the nanometer scale. They are emerging as a new class of biological label with properties and applications that are not available with traditional organic dyes and fluorescent proteins. Recent advances, as reported in Science and Nature Biotechnology, have led to quantum dot bioconjugates that are highly luminescent and stable. These bioconjugates raise new possibilities for studying genes, proteins and drug targets in single cells, tissue specimens and even in living animals.

Chromatography and electrophoresis on chips: critical elements of future integrated, microfluidic analytical systems for life science.

Liquid chromatography and electrophoresis played a major role in the life-science revolution, most strikingly in protein purification, peptide fractionation and sequencing, amino acid analysis, and DNA sequencing. The objective of this article is to examine the potential role of separation systems in the continuing evolution of biochemistry, biotechnology and molecular biology. Very small chip-based systems may change how chemical analyses in biology, medical research and health care evolve over the next decade.

Evaluating the use of streaming video to support student learning in a first-year life sciences course for student nurses.

Streaming video was used to support the learning of first year student nurses on a Life Sciences module, as one of many innovations designed to increase the range of resources and support available to students. This paper describes the background to this innovation, the procedures adopted and the results of extensive evaluation. The use of streaming video was evaluated in three applications in the module. A total of 656 students used online directed-learning sessions that incorporated streamed video. Just over half of these students actually viewed the video streams. Their feedback showed that 32% found access easy, 59% enjoyed using the resources, and 25% were very confident that they learned from them. Different types of video were used, and embedded in diverse ways, but the results were consistent across the three applications. They suggest that streamed video can contribute to useful resources to support learning by student nurses but, for a variety of reasons, it may not appeal or be adequately accessible to all students at present.

From classroom theory to clinical practice: evaluating the impact of a post-registration course.

This paper is concerned with the translation of bioscience theory into clinical practice. The empirical data form part of an action research study undertaken to investigate the clinical outcomes of the bioscience component of a post-registration, day release diploma in nursing taught in a higher education institution. Evidence for the impact of the course on patient care was collected by academic diary, questionnaire and interview. The triangulated data indicated that by adapting the pedagogic interpretation of the biosciences, it is possible to bridge the theory-practice gap. As a result, some nurses related the substance of the lessons to their patients, in order to bring about improvements in care. This paper examines the reasons behind the successes and failures of this continuing professional education initiative.

Life sciences flight hardware development for the International Space Station.

During the construction phase of the International Space Station (ISS), early flight opportunities have been identified (including designated Utilization Flights, UF) on which early science experiments may be performed. The focus of NASA's and other agencies' biological studies on the early flight opportunities is cell and molecular biology; with UF-1 scheduled to fly in fall 2001, followed by flights 8A and UF-3. Specific hardware is being developed to verify design concepts, e.g., the Avian Development Facility for incubation of small eggs and the Biomass Production System for plant cultivation. Other hardware concepts will utilize those early research opportunities onboard the ISS, e.g., an Incubator for sample cultivation, the European Modular Cultivation System for research with small plant systems, an Insect Habitat for support of insect species. Following the first Utilization Flights, additional equipment will be transported to the ISS to expand research opportunities and capabilities, e.g., a Cell Culture Unit, the Advanced Animal Habitat for rodents, an Aquatic Facility to support small fish and aquatic specimens, a Plant Research Unit for plant cultivation, and a specialized Egg Incubator for developmental biology studies. Host systems (Figure 1A, B: see text), e.g., a 2.5 m Centrifuge Rotor (g-levels from 0.01-g to 2-g) for direct comparisons between g and selectable g levels, the Life Sciences Glovebox for contained manipulations, and Habitat Holding Racks (Figure 1B: see text) will provide electrical power, communication links, and cooling to the habitats. Habitats will provide food, water, light, air and waste management as well as humidity and temperature control for a variety of research organisms. Operators on Earth and the crew on the ISS will be able to send commands to the laboratory equipment to monitor and control the environmental and experimental parameters inside specific habitats. Common laboratory equipment such as microscopes, cryo freezers, radiation dosimeters, and mass measurement devices are also currently in design stages by NASA and the ISS international partners.

The ambivalence of error: "scientific ideology" in the history of the life sciences and psychosomatic medicine.

This paper discusses the concept of "scientific ideology" as it appears in the work of the historian and philosopher of medicine Georges Canguilhem, whose work is becoming increasingly well known and used amongst anglophone social scientists. Whilst addressing the problematic of legitimacy and illegitimacy in the history of science, the concept of "scientific ideology" does something different and more complex than either the opposition between science and false science, or the one between orthodoxy and heresy, allow for. On the one hand, it enables us to preserve a crucial acknowledgment of the specificity of science in general, and of medical science in particular. On the other hand, it also allows us to challenge the sharp contrast between science and non-science by setting that contrast in a diachronic perspective. Drawing also on the work of Isabelle Stengers, the last part of the paper discusses an application of the concept of scientific ideology in relation to the field of psychosomatic medicine and psychoneuroimmunology.

Addendum to a note regarding the success of biological and medical science.

Much like mathematics, the biological and medical sciences seem unreasonably successful, considering many potential obstacles to this outcome. A recent suggestion that data should be viewed as 'quantized', that each 'elementary system' contains a single 'bit' of information (A. Zeilinger, A foundational principle for quantum mechanics, Foundations of Physics 29 (1999) 631), would seem ultimately to underlie the coherent relationships between the perceived physical universe and mental constructs within and among mathematics, logic, the 'hard' sciences and those 'softer' sciences directly based on biochemical and physiologic mechanisms (A. Zeilinger, A foundational principle for quantum mechanics, Foundations of Physics 29 (1999) 631; H. C. Von Baeyer, In the beginning was the bit, New Scientist, 17 (2000) 26-30).

Ethical issues for bioscientists in the new millennium.

The scientific understanding of biological processes is developing extremely fast, providing opportunities for changing people's lives in many ways-through health care, food and the environment. The speed with which these changes are occurring means that even bioscientists can only keep up with their own narrow field of science. It is not surprising that members of the public are frightened about the rapidity and impact of the changes arising from the biological revolution. These concerns are often expressed in ethical terms. Decision making about the direction of research and its application is becoming more transparent. This means that bioscientists will have to engage in the debate about their work with members of the public, including those who are opposed to it, in order to create acceptance of their work and its products. At the moment, bioscientists are often ill equipped to enter this debate because of their lack of training in ethics and lack of understanding of the impact of ethics on their work. A better understanding of bioethics will be necessary for entering this debate with vigour. A comprehensive ethical analysis is outside the scope of this text. Some of the principal arguments about the ethics of two aspects of bioscience research-genetically modified crops and the use of experimental animals-will be discussed to illustrate a few of the issues that derive from ethical analyses. I hope that this will encourage toxicologists to take a greater interest in bioethics.
