Authorship of peer-reviewed journal articles and abstracts has become the primary currency and reward unit in academia. Such a reward is crucial for students and postdocs who are often under-compensated and thus highly value authorship as an incentive. While numerous scientific and publishing organizations have written guidelines for determining author qualifications and author order, there remains much ambiguity when it comes to how these criteria are weighed by research faculty. Here, we sought to provide some initial insight on how faculty view the relative importance of 11 criteria for scientific authorship. We distributed an online survey to 564 biomedical engineering, biology, and bioengineering faculty members at 10 research institutions across the United States. The response rate was approximately 18%, resulting in a final sample of 102 respondents. Results revealed an agreement on some criteria, such as time spent conducting experiments, but there was a lack of agreement regarding the role of funding procurement. This study provides quantitative assessments of how faculty members in the biosciences evaluate authorship criteria. We discuss the implications of these findings for researchers, especially new graduate students, to help navigate the discrepancy between official policies for authorship and the contributions that faculty truly value.

Background: ImageJ is an image analysis program extensively used in the biological sciences and beyond. Due to its ease of use, recordable macro language, and extensible plug-in architecture, ImageJ enjoys contributions from non-programmers, amateur programmers, and professional developers alike. Enabling such a diversity of contributors has resulted in a large community that spans the biological and physical sciences. However, a rapidly growing user base, diverging plugin suites, and technical limitations have revealed a clear need for a concerted software engineering effort to support emerging imaging paradigms, to ensure the software's ability to handle the requirements of modern science. Results: We rewrote the entire ImageJ codebase, engineering a redesigned plugin mechanism intended to facilitate extensibility at every level, with the goal of creating a more powerful tool that continues to serve the existing community while addressing a wider range of scientific requirements. This next-generation ImageJ, called "ImageJ2" in places where the distinction matters, provides a host of new functionality. It separates concerns, fully decoupling the data model from the user interface. It emphasizes integration with external applications to maximize interoperability. Its robust new plugin framework allows everything from image formats, to scripting languages, to visualization to be extended by the community. The redesigned data model supports arbitrarily large, N-dimensional datasets, which are increasingly common in modern image acquisition. Despite the scope of these changes, backwards compatibility is maintained such that this new functionality can be seamlessly integrated with the classic ImageJ interface, allowing users and developers to migrate to these new methods at their own pace. Conclusions: Scientific imaging benefits from open-source programs that advance new method development and deployment to a diverse audience. ImageJ has continuously evolved with this idea in mind; however, new and emerging scientific requirements have posed corresponding challenges for ImageJ's development. The described improvements provide a framework engineered for flexibility, intended to support these requirements as well as accommodate future needs. Future efforts will focus on implementing new algorithms in this framework and expanding collaborations with other popular scientific software suites. [ABSTRACT FROM AUTHOR]

The field of “child study” emerged at the end of the nineteenth century with the purpose of disclosing children's “nature” for the benefit of parents, educators, psychologists, and other interested groups. Borrowed from the biological sciences, narratives of biological recapitulation were common in the discourses about child development during this period. Such theories often measured children against “savages,” but they also suggested that the study of childhood offered clues into the evolutionary relationships between humans and animals. By emphasizing the relevance of children's “instincts,” observers of child development explained child behavior as the tissue that linked humans and animals. © 2005 Wiley Periodicals, Inc.

Genioglossus is the largest upper airway dilator and its dilatory movement can be measured non-invasively with magnetic resonance imaging and ultrasound. The present study used a novel ultrasound method to assess genioglossus movement in conditions in which ventilatory drive or respiratory mechanics were changed. Methods: Twenty healthy subjects (10 males, age 28±5 years [mean ± SD]) lay supine, awake, with the head in a neutral position. Ventilation was monitored with inductance bands. Real-time B-mode ultrasound movies were analysed. We measured genioglossus motion (i) during spontaneous breathing, voluntary targeted breathing (normal tidal volume Vt), and voluntary hyperpnoea (at 1.5Vt and 2 Vt); (ii) during inspiratory flow resistive loading; (iii) with changes in end-expiratory lung volume (EELV). Results: Average peak inspiratory displacement of the infero-posterior region of genioglossus was 0.89±0.56 mm; 1.02±0.88 mm; 1.27±0.70 mm respectively for voluntary Vt, and during voluntary hyperpnoea at 1.5Vt and 2Vt. A change in genioglossus motion was observed with increased Vt. During increasing inspiratory resistive loading, the genioglossus displaced less anteriorly (p = 0.005) but more inferiorly (p = 0.027). When lung volume was altered, no significant changes in genioglossus movement were observed (p = 0.115). Conclusion: In healthy subjects, we observed non-uniform heterogeneous inspiratory motion within the inferoposterior part of genioglossus during spontaneous breathing with mean peak displacement between 0.5–2 mm, with more displacement in the posterior region than the anterior. This regional heterogeneity disappeared during voluntary targeted breathing. This may be due to different neural drive to genioglossus during voluntary breathing. During inspiratory resistive loading, the observed genioglossus motion may serve to maintain upper airway patency by balancing intraluminal negative pressure with positive pressure generated by upper airway dilatory muscles. In contrast, changes in EELV were not accompanied by major changes in genioglossus motion. [ABSTRACT FROM AUTHOR]

The search for once-habitable locations on Mars is increasingly focused on environments dominated by fluvial and lacustrine processes, such as those investigated by the Mars Science Laboratory Curiosity rover. The availability of liquid water coupled with the potential longevity of such systems renders these localities prime targets for the future exploration of Martian biosignatures. Fluvial-lacustrine environments associated with basaltic volcanism are highly relevant to Mars, but their terrestrial counterparts have been largely overlooked as a field analogue. Such environments are common in Iceland, where basaltic volcanism interacts with glacial ice and surface snow to produce large volumes of meltwater within an otherwise cold and dry environment. This meltwater can be stored to create subglacial, englacial, and proglacial lakes, or be released as catastrophic floods and proglacial fluvial systems. Sedimentary deposits produced by the resulting fluvial-lacustrine activity are extensive, with lithologies dominated by basaltic minerals, low-temperature alteration assemblages (e.g., smectite clays, calcite), and amorphous, poorly crystalline phases (basaltic glass, palagonite, nanophase iron oxides). This paper reviews examples of these environments, including their sedimentary deposits and microbiology, within the context of utilising these localities for future Mars analogue studies and instrument testing.

Life science research and life sciences' industries are facing an overwhelming complexity of biology. Today's scientific methods and technologies allow for a very detailed look at biology. What is left to do, is understanding and interpretation. Quantitative biology, the close coupling of life sciences, mathematics, and statistics is likely to provide the methodologies to turn collected data into dedicated information and knowledge. The most promising approach is the formulation of mathematical models on the basis of machine learning. The predictive power of such an approach is a promising option for basic biological research, medicine, pharmacology, agricultural science, and ecology. Furthermore, also R&D of related life sciences industries can take advantage of this digital approach to meet future challenges and market requirements. Quantitative biology plays the role of an enabling technology. [ABSTRACT FROM AUTHOR]

This article provides information on two examples of some early progress in the field of synthetic biology, as of June 2004. During the 1940s, John von Neumann, popular in the development of modern computers, investigated the theoretical possibilities of self-reproduction. Von Neumann essentially asserted that a self-reproducible machine would require a tape or other description of itself. During reproduction, this tape would serve as the set of instructions for building a copy of the machine and would itself be copied to create the seed necessary for the next generation. Apparently, DNA turned out to have precisely such properties. One of the very first computer scientists, a mathematician and engineer, made a prediction of the fundamental mechanism of life that biologists subsequently discovered. Allegedly, in a forthcoming denouement, engineering is poised for a triumphant comeback in molecular biology. The last fifty years of molecular biology have largely been devoted to understanding the incredibly complex mechanisms that govern life. Scientists have developed wonderful analytic tools to study what goes on in cells. Presently, experts are on the brink of an engineering revolution that will allegedly transform the ability to manipulate the biological world.

This article describes the development of the fundamental principles of the science of life, which are equivalent to those of the natural (hard) sciences, such as physics and chemistry. The natural sciences are typified by identification of universal phenomena, relations among these phenomena and fundamental measures and units of measure for these phenomena. It is shown that matter, energy, knowledge, information and behaviour are universal phenomena of life and that there are relations among these phenomena. Units of measure for these phenomena were previously developed, except for knowledge. The principles of life sciences are developed using the natural sciences (Newton) development model. Names are also suggested for new dimensions of quantitative measures of biochemical, genetic and neural knowledge. Copyright © 2012 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

The sustainability of radiation biology (radiobiology) is under threat in South Africa because of underdevelopment in the discipline, despite the fact that South Africa has been a user of radiation since radioactivity and X-rays were discovered. The widespread use of radiation in medicine, nuclear reactors, particle accelerators and other sophisticated nuclear facilities in South Africa makes it imperative that the interaction of radiation with biological systems is understood. For example, radiobiology is critical in radiation oncology and cancer treatment. Radiobiology is a distinctly biological science and its uniqueness and value should be highlighted to provide insight for authorities and other relevant parties. Regrettably, radiobiology has been largely neglected despite the importance of maintaining expertise and competence in this discipline. Many radiation-associated disciplines require radiobiology for their training and practice yet few radiobiologists are available nationally. The scientific community needs to be informed of the predicament of radiobiology in South Africa so that the situation can be addressed. Radiobiology is a scarce skill that needs to be developed to support South Africa's mature radiation infrastructure. The country has too few radiobiologist training programmes and there is a lack of succession planning. Radiobiology is required for training and practice in a number of disciplines that use radiation, but, as a result of a shortage of qualified personnel, teaching of radiobiology has frequently been conducted by non-experts. To reinvigorate radiobiology in South Africa, a collective effort by government, academia, industry and allied professionals is required. [ABSTRACT FROM AUTHOR]

Allometric equations are widely used in many branches of biological science. The potential information content of the normalization constant b in allometric equations of the form Y=bXa has, however, remained largely neglected. To demonstrate the potential for utilizing this information, I generated a large number of artificial datasets that resembled those that are frequently encountered in biological studies, i.e., relatively small samples including measurement error or uncontrolled variation. The value of X was allowed to vary randomly within the limits describing different data ranges, and a was set to a fixed theoretical value. The constant b was set to a range of values describing the effect of a continuous environmental variable. In addition, a normally distributed random error was added to the values of both X and Y. Two different approaches were then used to model the data. The traditional approach estimated both a and b using a regression model, whereas an alternative approach set the exponent a at its theoretical value and only estimated the value of b. Both approaches produced virtually the same model fit with less than 0.3% difference in the coefficient of determination. Only the alternative approach was able to precisely reproduce the effect of the environmental variable, which was largely lost among noise variation when using the traditional approach. The results show how the value of b can be used as a source of valuable biological information if an appropriate regression model is selected. [ABSTRACT FROM AUTHOR]

Data management and integration are complicated and ongoing problems that will require commitment of resources and expertise from the various biological science communities. Primary components of successful cross-scale integration are smooth information management and migration from one context to another. We call for a broadening of the definition of bioinformatics and bioinformatics training to span biological disciplines and biological scales. Training programs are needed that educate a new kind of informatics professional, Biological Information Specialists, to work in collaboration with various discipline-specific research personnel. Biological Information Specialists are an extension of the informationist movement that began within library and information science (LIS) over 30 years ago as a professional position to fill a gap in clinical medicine. These professionals will help advance science by improving access to scientific information and by freeing scientists who are not interested in data management to concentrate on their science.
