Exploring the Intricacies of Life Science: An Essay on the Wonders of the Natural World
What is most important about this definition is the emphasis on the application part of life science as a way to solve the problems and challenges that face human beings. It is reflected in a philosophy of education that has human beings, including pre-service and in-service K-12 teachers, being active in the types of practices that the enterprise of science has its practitioners involved with, instead of being passive isolated onlookers.
Life science is the useful practical application of the body of knowledge and information known as biology to serve human beings. In Holly Knapp’s “Life Science,” the actual application part includes “life science process skills, vocabulary and concepts, laboratory investigations, math connections, physical education connections, writing connections, citizenship connections, history and culture connections, art connections, homework activities, Spanish activities, the world of Life Science, and assessment.” These themes promote authentic learning around a wide range of subjects.
The biological sciences have always had as their main focus the concepts of the unity and diversity of life. Throughout the ages, anyone interested in life science and looking at the natural world saw many common features. All living organisms looked, behaved, and developed in similar ways, and there was not then, nor is there today, any really sharp dividing line separating the members of the living from the nonliving world. There are no very distinctive characteristics such as physical size, chemical composition, or energy changes by which the entire group of living organisms can be defined and separated from the entire group of nonliving materials.
Life science, also known as the biological sciences, is the study of the many different varieties of living organisms, including animals, plants, fungi, and microorganisms such as bacteria and protozoans. Included in the life sciences are biological fields such as botany, zoology, ecology, and microbiology, each of which deals with a particular category of living organisms and related problems. In recent years, the rapid strides made in biochemistry, cell biology, and genetics have resulted in enormous advances in the overall life sciences and have further broadened their scope of inquiry.
Bringing together our strengths in the life sciences could lead to the development of an impressive range of biotechnology applications with medical, agronomic, environmental, and societal significance. However, before further strengthening the industrial position of the life sciences, it is worth remembering that advances in biotechnology pose fundamental questions about the relationships between biotechnology, health, the environment, and the definition of a ‘World Society’. These are not only scientific questions, but are also ethical, economic, social, and political ones. Fostering discussions on biotechnology is vital, so too is providing the public with information about science, its methods, and its societal implications. Clearly, a ‘World Society’ needs to have the ability, the desire, and the freedom to choose how to benefit from fundamental advances in the life sciences, particularly in areas such as human health, the environment, and food.
One reason why the life sciences enjoy such strong support is because they are so deeply integrated into modern society – albeit often in ways that are not visible. From the use of synthetic sequences for vaccines, drugs, and other chemicals, to the development of bioinformatics software and the growth of the biotechnology and pharmaceutical industries, the life sciences have spawned a vast range of applications that are vital for the future; they are also responsible for substantial financial returns. Trade and investment are major stimulus activities in research, discoveries, applications, and employment. Furthermore, the biological and medical needs of developing countries, and of society as a whole, can only be addressed through innovation and the provision of effective, economical, medically affordable solutions. Ensuring that biological research serves society as effectively as possible requires the close participation of stakeholders than has been the case in the past.
The transformation of life sciences computing is driven in part by the requirements of critical biological and biomedical issues and scientific problems. Notable trends include the broader interface and interdisciplinary transformation between information and life sciences, in-depth remote sensing, analysis, and modeling for observation of biological processes, emergence of new techniques for generating and working with data, and modifications and re-engineering of methods and algorithms for interpretational and knowledge delivery information from existing and exploratory data. Despite the challenges and barriers still facing life science, the potential rewards are striking. They include the reinvention of disease, considering it in the context of biology with the promise of identification of biomedically useful targets; the ability to sequence, identify, and ultimately annotate the complete genomes of many microbial and other organisms; the understanding of simple genetic diseases; the analysis of the development, evolution, and enumeration of biological processes; and revolutionizing strategies for understanding and discovering compounds.
At the heart of life sciences are advances in molecular genetics and cellular biology that have resulted in extraordinary technical innovation. Some of the recent advances have led to exciting new developments in the alignment of these innovations with biological problems. The future is expected to bring further advances, and it is increasingly likely that solutions to fundamental questions in brain science, aging, and disease will emerge from a new perspective. Over the past decade or so, life science has evolved into bio-analytical technologies, high-performance computational methods for modeling existing data and discovering useful patterns, and new applications of the concepts of genomics, proteomics, and bioinformatics to those problems that ultimately contribute to our understanding of how the results of these analyses reach the patient.
