Give cosmic sense to next generations through cosmic/space biology]

Life sciences are currently most important fields for every person. Each subject of life sciences is deeply correlated to cosmic events, and young generations can be more interested in life sciences if they know this correlation. In this respect, cosmic/space biology can play essential roles in fostering the science-oriented generations. Some approaches to realize the above concepts are presented.     

Aerodynamically assisted jetting and threading for processing concentrated suspensions containing advanced structural,functional and biological materials

In recent years material sciences have been interpreted right across the physical and the life sciences. Essentially this discipline broadly addresses the materials, processing, and/or fabrication right up to the structure. The materials and structures areas can range from the micro- to the nanometre scale and, in a materials sense, span from the structural, functional to the most complex, namely biological (living cells). It is generally recognised that the processing or fabrication is fundamental in bridging the materials with their structures. In a global perspective, processing has not only contributed to the materials sciences but its very nature has bridged the physical with the life sciences. In this review we discuss one such swiftly emerging fabrication approach having a plethora of applications spanning the physical and life sciences.

Competencies in premedical and medical education: the AAMC-HHMI report

One hundred years ago, Flexner emphasized the importance of science in medicine and medical education. Over the subsequent years, science education in the premedical and medical curricula has changed little, in spite of the vast changes in the biomedical sciences. The National Research Council, in their report Bio 2010, noted that the premedical curriculum caused many students to lose interest in medicine and in the biological sciences in general. Many medical students and physicians have come to view the premedical curriculum as of limited relevance to medicine and designed more as a screening mechanism for medical school admission. To address this, the Association of American Medical Colleges and the Howard Hughes Medical Institute formed a committee to evaluate the premedical and medical school science curricula. The committee made a number of recommendations that are summarized in this essay. Most important were that competencies replace course requirements and that the physical sciences and mathematics be better integrated with the biological sciences and medicine. The goal is that all physicians possess a strong scientific knowledge base and come to appreciate the importance of this to the practice of medicine. While science education needs to evolve, Flexner's vision is as relevant today as it was 100 years ago.     

Bio-electrosprays: the development of a promising tool for regenerative and therapeutic medicine

Regenerative and therapeutic medicine are two fields of research to which engineering sciences are increasingly contributing. One such case in which physical sciences have been greatly involved is in the generation of tissues by directly processing living cells. In this article we focus on the current status of cell or tissue engineering approaches by way of jets, particularly focusing on bio-electrosprays.     

Data clustering in life sciences

Clustering has a wide range of applications in life sciences and over the years has been used in many areas ranging from the analysis of clinical information, phylogeny, genomics, and proteomics. The primary goal of this article is to provide an overview of the various issues involved in clustering large biological datasets, describe the merits and underlying assumptions of some of the commonly used clustering approaches, and provide insights on how to cluster datasets arising in various areas within life sciences. We also provide a brief introduction to Cluto, a general purpose toolkit for clustering various datasets, with an emphasis on its applications to problems and analysis requirements within life sciences.     

From crop domestication to super-domestication

Research related to crop domestication has been transformed by technologies and discoveries in the genome sciences as well as information-related sciences that are providing new tools for bioinformatics and systems' biology. Rapid progress in archaeobotany and ethnobotany are also contributing new knowledge to understanding crop domestication. This sense of rapid progress is encapsulated in this Special Issue, which contains 18 papers by scientists in botanical, crop sciences and related disciplines on the topic of crop domestication. One paper focuses on current themes in the genetics of crop domestication across crops, whereas other papers have a crop or geographic focus. One feature of progress in the sciences related to crop domestication is the availability of well-characterized germplasm resources in the global network of genetic resources centres (genebanks). Germplasm in genebanks is providing research materials for understanding domestication as well as for plant breeding. In this review, we highlight current genetic themes related to crop domestication. Impressive progress in this field in recent years is transforming plant breeding into crop engineering to meet the human need for increased crop yield with the minimum environmental impact - we consider this to be 'super-domestication'. While the time scale of domestication of 10 000 years or less is a very short evolutionary time span, the details emerging of what has happened and what is happening provide a window to see where domestication might - and can - advance in the future.     

New tools and new biology: Recent miniaturized systems for molecular and cellular biology

Recent advances in applied physics and chemistry have led to the development of novel microfluidic systems. Microfluidic systems allow minute amounts of reagents to be processed using μm-scale channels and offer several advantages over conventional analytical devices for use in biological sciences: faster, more accurate and more reproducible analytical performance, reduced cell and reagent consumption, portability, and integration of functional components in a single chip. In this review, we introduce how microfluidics has been applied to biological sciences. We first present an overview of the fabrication of microfluidic systems and describe the distinct technologies available for biological research. We then present examples of microsystems used in biological sciences, focusing on applications in molecular and cellular biology.     

From theory to data: Representing neurons in the 1940s

Recent literature on the role of pictorial representation in the life sciences has focused on the relationship between detailed representations of empirical data and more abstract, formal representations of theory. The standard argument is that in both a historical and epistemic sense, this relationship is a directional one: beginning with raw, unmediated images and moving towards diagrams that are more interpreted and more theoretically rich. Using the neural network diagrams of Warren McCulloch and Walter Pitts as a case study, I argue that while in the empirical sciences, pictorial representation tends to move from data to theory, in areas of the life sciences that are predominantly theoretical, when abstraction occurs at the outset, the relationship between detail and abstraction in pictorial representations can be of a different character.     

The limits of reductionism in the life sciences

In the contemporary life sciences more and more researchers emphasize the "limits of reductionism" (e.g. Ahn et al. 2006a, 709; Mazzocchi 2008, 10) or they call for a move "beyond reductionism" (Gallagher/Appenzeller 1999, 79). However, it is far from clear what exactly they argue for and what the envisioned limits of reductionism are. In this paper I claim that the current discussions about reductionism in the life sciences, which focus on methodological and explanatory issues, leave the concepts of a reductive method and a reductive explanation too unspecified. In order to fill this gap and to clarify what the limits of reductionism are I identify three reductive methods that are crucial in the current practice of the life sciences: decomposition, focusing on internal factors, and studying parts in isolation. Furthermore, I argue that reductive explanations in the life sciences exhibit three characteristics: first, they refer only to factors at a lower level than the phenomenon at issue, second, they focus on internal factors and thus ignore or simplify the environment of a system, and, third, they cite only the parts of a system in isolation.     

Protecting the human subjects of social science research--the role of institutional review boards

Current and proposed reforms of the regulatory schema for protecting human subjects of research have focused attention on Institutional Review Board (IRB) responsibilities. Consensus on the need for strengthening the oversight of these boards is all but certain--with the exception of research in the social and behavioral sciences, where an argument for less oversight is being made. The thesis in this article is that respecting the salient features of research in the social and behavioral sciences will ameliorate the tensions leading to this demand and offer better protection to the subjects of social and behavior studies.     

Biology in the secondary science curriculum

The search for a model of balanced science has not so far been based on a detailed analysis of the nature and effects of the science curriculum. The present paper attempts to begin to fill the gap, from the perspective of biology, using data from the Assessment of Perform-ance Unit (APU). It is shown that, in England, the uptake of the subject as an option outstrips that of the other sciences, with pupils quoting its intrinsic interest as their motivation. Biology serves to attract to science pupils of all abilities and girls in particular. The other sciences are not so successful in this sphere. However, performance data show that the study of biology is not as effective in enhancing science performance as are the physical sciences.     

Past, present and future of atomic force microscopy in life sciences and medicine

Revolutions in the earth sciences

The 20th century has been a century of scientific revolutions for many disciplines: quantum mechanics in physics, the atomic approach in chemistry, the nonlinear revolution in mathematics, the introduction of statistical physics. The major breakthroughs in these disciplines had all occurred by about 1930. In contrast, the revolutions in the so-called natural sciences, that is in the earth sciences and in biology, waited until the last half of the century. These revolutions were indeed late, but they were no less deep and drastic, and they occurred quite suddenly. Actually, one can say that not one but three revolutions occurred in the earth sciences: in plate tectonics, planetology and the environment. They occurred essentially independently from each other, but as time passed, their effects developed, amplified and started interacting. These effects continue strongly to this day.
