We describe an interdisciplinary research project for undergraduate students involving microbiology and public health. Students designed and carried out two research studies on hand hygiene and the use of gloves by mobile food vendors in New York City and in a New Jersey mall. Students received training in aseptic techniques and survey methodology to carry out the multifaceted study. We discuss the importance of interdisciplinary collaboration and research in the context of its value in preparing professionals in the fields of biology and public health.

ABSTRACT: Academic literature has paid scant attention to the biological sciences at Stanford University, an omission all the more conspicuous considering their productivity since World War II. This article draws on previously unused archival material to establish a starting point for further study of the biological sciences at Stanford. It traces the evolution of Stanford's biological sciences through three experimental fields: self-directed developmental and evolutionary studies; fundamental research at the molecular level; and biomedical applications of fundamental knowledge.

Intellectual Property is a powerful legal and economic instrument. In our “knowledge economy”, patents are the preferred IP tool with special emphasis in the pharma – agro biotech industry. However, the growth of patents in the bio sector such as the pharma and agro fields, encounters many challenges. Life itself has not been defined yet. So, how can it be determined exactly when a living being, or a biological entity has been modified by itself or by human intervention, and thus address issues of patentability? Therefore, a researcher in the bio field cannot be alien to Intellectual Property,

Unmanned Aerial Vehicles (UAV) have technical capabilities to extended usage in various fields ofscience. The existing UAVs are to be relatively easily accessible in the near future. It is possible to equip them with different sensors but there are still some usage limitations. This paper focuses ondemonstrating UAVs usage for research in polar regions. The research in polar regions is very specific and, due to harsh climate, limits the field work with UAVs. The options and limitations are presented in a case study performed in the Nordenskiöldbreen area, Svalbard Archipelago. In the end some

AbstractMany farmers and consumers are reevaluating chemical weed control because of the environmental risks of herbicides and their influence on farm size and diversity. This paper reviews research of the last 35 years on mechanical and cultural weed control in corn(Zea maysL.)and soybeans(Glycine maxL.).Soybeans can better use the weed control advantages of late planting and narrow row spacing and are less affected by early stand losses from mechanical weed control. In Minnesota, delaying planting to early June allows early germinating weeds to be controlled by preplant tillage but reduces t

Combining law and the brain as a matter for study requires the integration not just of two apparently remote fields of study but also of two profoundly different orientations towards research and study. We believe that, in spite of the difficulties, such a combination, perhaps even emerging in a new specialized discipline in the future, will not only enrich both fields but is the ineluctable consequence of the current assault on the secrets of the brain. The effort to bring the fields together is therefore a worthy task, and this issue is the first systematic effort to test this expectation.

SUMMARY Currently, genetic typing of microorganisms is widely used in several major fields of microbiological research. Taxonomy, research aimed at elucidation of evolutionary dynamics or phylogenetic relationships, population genetics of microorganisms, and microbial epidemiology all rely on genetic typing data for discrimination between genotypes. Apart from being an essential component of these fundamental sciences, microbial typing clearly affects several areas of applied microbiogical research.

The tropical dry forest is a typical lowland ecosystem that is threatened by a strong seasonality and anthropogenic pressures, which can affect the forest composition and structure. The objective of this study was to estimate the impact of two agricultural matrices on the floristic composition and carbon storage in riparian forests. For this, five permanent plots (10 x 10 m each) were established and sampled in the forest interior and at the edge of two agricultural matrices (rice fields and pasture lands), in July 2013.

Abstract Discussions of reproducibility are casting doubts on the credibility of experimental outcomes in the life sciences. Although experimental evolution is not typically included in these discussions, this field is also subject to low reproducibility, partly because of the inherent contingencies affecting the evolutionary process. A received view in experimental studies more generally is that standardization (i.e., rigorous homogenization of experimental conditions) is a solution to some issues of significance and internal validity. However, this solution hides several difficulties, includ

Recent developments in our understanding of memory processes and mechanisms, and their digital implementation, have placed the encoding, storage, management and retrieval of information at the forefront of several fields of research. At the same time, the divisions between the biological, physical and the digital worlds seem to be dissolving. Hence, opportunities for interdisciplinary research into memory are being created, between the life sciences, social sciences and physical sciences. Such research may benefit fro

AbstractTo promote agricultural sustainability, there is a growing interest in developing soil quality indicators that can be used as early indicators of changes in management practices by growers, agricultural professionals, and researchers. A study was conducted on four commercial growers' fields and two research stations in western Oregon with treatments that had been started from 1 to 7 years prior to initiating the investigation. The primary comparison at each site was a winter cover crop and winter fallow in rotation with summer vegetable crops. The effects of these treatments on microbi

The premise of this two-part theme issue is simple: the cognitive sciences should join the rest of the life sciences in how they approach the quarry within their research domain. Specifically, understanding how organisms on the lower branches of the phylogenetic tree become familiar with, value and exploit elements of an ecological niche while avoiding harm can be expected to aid understanding of how organisms that evolved later (including Homo sapiens ) do the same or similar things. We call this approach basal cognition. In this introductory essay, we explain what the approach involves. Beca

In this article, technical and socio-economic aspects of small ruminant production systems on the Adja Plateau are described. Monitoring of small ruminant flocks showed that about 25% of the small ruminants were sold annually. Export of nutrients as a result of the sale of animals (85 g N. 23 g P. 12 g K and 46 g Ca per hectare) was low compared with export through crop production.

Agricultural land set up systems comprise those agronomic structures able to preserve the soil fertility from water erosion, such as: ditching, contouring, earth-riser and stonewall terracing, draining, and channelization, etc.. However, in the past 60 years, agricultural mechanization has led to an expansion of the field size and reduction in land set up system intensity to make machine operation more feasible and cheaper. As a consequence, these transformations have made sloping fields less resilient to the storms and accelerated the soil erosion processes. Based on an 8- year field study in
