Science is a way of looking at the world, a system for increasing our knowledge of the world, a tool for making decisions about how to act in the world. Fundamentally, science provides a structure for exploration: the scientific method, a well-defined system that scientists worldwide recognize as the basis for scientific understanding.

The scientific method, a system of hypothesis generation and testing, is the same whether used by laboratory scientists, epidemiologists, wildlife biologists, or others. A scientist begins with a curiosity about some particular topic and a question. Based on the scientist's previous observations and experience, she develops a hypothesis about how, why, or whether a particular phenomenon occurs. Next, she develops a test, or an experiment, to see how her hypothesis holds ap in the face of the evidence. In fact she is testing two hypotheses: the second, called the null hypothesis, is essentially the negative of the hypothesis she has developed. If, for example, her hypothesis is that (1) treating rats with the solvent toluene will result in birth defects in their offspring, the null hypothesis will state that (2) treating rats with toluene will not result in birth defects. Although it may seem counterintuitive, the scientist proceeds from the assumption that the null hypothesis is true.

Health science is the applied science dealing with health, and it includes many sub disciplines.
There are two approaches to health science: the study and research of the human body and health-related issues to understand how humans (and animals) function, and the application of that knowledge to improve health and to prevent and cure diseases.
Health research builds upon the basic sciences of biology, chemistry, and physics as well as a variety of multidisciplinary fields (for example medical sociology). Some of the other primarily research-oriented fields that make exceptionally significant contributions to health science are alternative health, biochemistry, epidemiology, and genetics,natural health.
Applied health sciences also endeavor to better understand health, but in addition they try to directly improve the health of individuals and of people in general. Some of these are: alternative health, biomedical engineering, biotechnology, nursing, nutrition, pharmacology, pharmacy, public health, psychology, physical therapy, and medicine. The provision of services to improve people's health is referred to as health care.
The health sciences industry, a multi-billion dollar business sector, is a cross-section of the life sciences and the health care and medical diagnostics industries.

Well Rinku,

The scientific method, a system of hypothesis generation and testing, is the same whether used by laboratory scientists, epidemiologists, wildlife biologists, or others. A scientist begins with a curiosity about some particular topic and a question. Based on the scientist's previous observations and experience, she develops a hypothesis about how, why, or whether a particular phenomenon occurs. Next, she develops a test, or an experiment, to see how her hypothesis holds ap in the face of the evidence. In fact she is testing two hypotheses: the second, called the null hypothesis, is essentially the negative of the hypothesis she has developed. If, for example, her hypothesis is that (1) treating rats with the solvent toluene will result in birth defects in their offspring, the null hypothesis will state that (2) treating rats with toluene will not result in birth defects. Although it may seem counterintuitive, the scientist proceeds from the assumption that the null hypothesis is true.

Many nonscientists are not aware of the role of the null hypothesis in the scientific method which can lead to misunderstandings between scientists and nonscientists. In the logic of the scientific method, a scientist looking for evidence to support a hypothesis must do so by disproving the corresponding null hypothesis. In other words if she finds in her experiment that rats treated with toluene do in fact give birth to many more offspring with birth defects than do untreated rats, then she can no longer say that treating rats with toluene will not lead to birth defects. She then rejects the null hypothesis, and her experimental results support, but do not prove, the original hypothesis.

When deciding whether she can reject the null hypothesis, the scientist will use specific statistical techniques to assess the results of her experiment to determine whether the results are statistically significant. Statistical significance is a measure of the likelihood that a result did not occur due to chance alone. If the scientist decides that her result is not statistically significant, she fails to reject the null hypothesis. She states that nothing statistically significant happened in her experiment to support her original hypothesis, and she must go on to develop another hypothesis or refine the current one.

If, however, she decides that her result is statistically significant, she rejects the null hypothesis. Now she is in a curious position: she has shown that her on nag hypothesis has been supported, but she leas riot roved her hypothesis. She has simply shown that she has not found any result that disagrees with her original hypotheses. This is the scientists' dilemma: they can only support, but never prove a hypothesis. With more research and further experimentation the original hypothesis can be refined and further supported, elevated to the status of a theory, but in the end, the truth of a hypothesis is a matter of judgement rather than h proof.

Nonscientists can be frustrated when scientists are unwilling to give absolute answers. The inability to provide such answers is one of the limitations of the scientific method. The scientist, knowing that her method of analyzing cannot absolutely prove a hypothesis, will tend to be conservative in making a statement about the truth of a hypothesis. She knows that further research may reveal that the hypothesis is inadequate in some way, and so will state that the science is incomplete. The scientist may feel fairly confident that her hypothesis is valid if there is a good body of research supporting it and numerous other researchers have confirmed her results, but she still cannot say that she is absolutely sure. Many of the difficulties in using science in the decisionmaking process thus have their roots in the very nature of the scientific method.

There are two approaches of science; to study and research human body and high related issues to understand the human functioning and application of that knowledge to improve health and cure diseases. The increase longevity of human over the past few years is due to large part to medical research. Major advancement in medicine has been vaccines for measles, polio; insulin treatment for diabetes, medication for high blood pressure, new surgical techniques such as microsurgery and successful treatments for cancer. Health science field is as old as human race, with modern technology and backing of pure sciences has greatly improved.

To assess the contributions of science to health improvements, the goal of care must be addressed. A much effort of science is devoted to preventive measures and large measurable effect on the life expectancy of the population as a whole. A most important role of science is devoted to improve the quality of life and to minimizing the poor quality of life associated with chronic disease like to the relief of pain and disability. Science and technology are now seen not only have a strong connection to our health and daily life but also to the society's economic growth and its capability to generate societal well being.

well, From specific incidences of emerging infectious diseases to the broad concerns about global industrial competitiveness, we know that science, technology, and health considerations permeate a vast array of issues that the Department of State grapples with every day," said Robert Frosch, chair of the Research Council committee that prepared the report, and senior research fellow at John F. Kennedy School of Government, Harvard University, Cambridge, Mass. "Yet ironically, as the world becomes more technologically interdependent, the trend at the State Department has been to downplay science and technical expertise. It's time to reverse that trend."

At a minimum, the committee said, all foreign service officers and other diplomatic officials should achieve basic competence in scientific, technological, and health matters. Recruitment, training, and promotion should recognize the importance of these skills. In addition, assignments in science, technology, and health should be considered an important asset for all officials on career tracks to ambassadorships.

The report also urges the secretary of state to appoint a highly qualified senior adviser on science, technology, and health. And it calls on the department to assign at least 25 technically trained science counselors with foreign policy expertise to serve at a comparable number of embassies in countries where issues of science, technology, and health are most critical to the United States. The department also should establish promotion and career incentives for service in positions related to these areas. At present, with occasional exceptions, the report says, the most highly talented foreign service officers are ill-equipped for and have little incentive to seek those jobs. In fact, science, technology, and health-related assignments may be a career handicap, rather than an asset, for foreign service officers who are encouraged to develop other essential skills, and serve in political and economic positions. The committee urged the department to reward - not penalize - foreign service officers for their technical experience and competence.

The report builds on interim recommendations the committee made to the department in the fall of 1998. In this final report, the committee notes that as yet there has been relatively little action on its earlier set of recommendations.

well,Science provides the foundation for credible decision making, adequate knowledge about risk to human health and innovative solutions to prevent diseases and offer high quality of life. Many chronic and infectious diseases are related to environment factors. High concentration of ozone, particulate matter can worsen respiratory diseases like asthma or emphysema. NASA's goal is to help to determine how weather, climate and environmental conditions correlate with the occurrence of infectious diseases. Public healths problems are caused by the environmental contamination are a growing concern worldwide. Public health threats are affected by the relationship between people and physical, chemical and biological nature of our environment. Science play a significant role in providing scientific knowledge and information that will improve our understanding of the environment conditions to diseases.

Science is a powerful means of understanding the world in which we live and it is also capable of yielding socio-economic development and enhance the quality of our lives. Science over the last fifty years have led to revolutionary changes in health and nutrition. National institute of health is the primary federal agency for conducting and supporting medical research. Scientists investigate ways to prevent disease, cause, and treatments of the common and rare diseases. National medical research agency provides leadership and financial support to researchers and scientists in every state through out the world. Science has played a significant role in improving health of the whole nation.

Medical science supports and conducts medical research how the human body works and to gain insight into diseases and disorders from rare to most familiar diseases. Science supports a wide spectrum of research from learning how brain becomes addicted to additives to combating heart disease. Science plays an important role for developing new ways of diagnosis and treat disease like cancer or other serious diseases. Science technology has improved new and imaging techniques that let scientists painlessly look inside body to detect diseases in its earliest stages.

Academically and technically considered, diagnostic, surgical and other skills of science is today far advanced. The knowledge of human body and its reactions to both external and internal stimuli is outstanding. All efforts of science are today concentrated on longevity of life. Man attitude will undergo a radical change when it is recognized that physical body is merely a channel of soul or its instrument of expression in the world of matter.
