BSC 1005 Notes
II. Busting Biology Myths Dr. Marie Charrel Dennis Chapter 1 What is Science?  - Scientific ResearchScientific Discoveries
- The term science applies to a remarkably broad set of human 
endeavors - The Scientific Branches  o 1. Natural Science Life Sciences: study the organization and life processes of 
living organisms
Examples: Ecology, Zoology, Taxonomy, Cell Biology, 
Immunology
Physical Sciences: study nature and the properties of 
energy and non-living matter.
Examples: Earth physical science (Geology, 
Paleontology, Meteorology, Physical science 
(Mechanics, Thermodynamics, Atomic, and Nuclear 
Physics or Chemistry
o 2. Formal Science disciplines develop formal systems to generate knowledge 
and are the foundation of many other scientific disciplines. 
Three main disciplines belong in the formal science
Examples: Mathematics, Logics, and Computer Science o 3. Social Science studies human groups and the relationships and individuals
within society
the study of social life of human groups o 4. Applied Science  concerned with using existing knowledge to develop 
practical applications
Example: Medicine, Agronomy/Horticulture, or Engineering - Safeguards & Cornerstones of Natural Sciences o Involve the scientific community
o Must be reproducible by others
o No way to secure complete & absolute truth 
- Scientists sometimes use various instruments to extend their senses  but overall use their intellect as their primary tool to design 
experiments, evaluate their results, and develop theories
- The scientific method is often depicted as a linear research model,  initiated by an observation, leading to the formulation of a hypothesis, 
background image followed by acquisition of data and terminated by a definite conclusion 
regarding the initial hypothesis.
- Errors:  o Potential misinterpretation of the data may represent type I or  type II errors. Type I: mistake of thinking something is true when it is not  “False positive” Type II: thinking something is not true when in fact it is “False negative” o LOOK at chart on page 2 - Epidemiology (EPI- upon, DEMI- people, OLOGY- study) o The basic science of public health
o This scientific discipline focuses on the study of how often 
diseases occur in different groups of people and why. o Studying a very specific/defined population
o To identify determinants associated with the development of 
diseases, epidemiologists first select a defined population to 
survey leading to the identification of parameters. Then they 
analyze how these parameters vary in time or as a function of 
the environment or within a subpopulation, for example. 
Prevalence: proportion of the population that has a disease at a  specific time point (new and old case) Incidence: new cases of disease during specified period of an  initially disease-free population that develop disease (risk, 
probability)
Descriptive study: is important to highlight a potential health  problem Case report Survey Analytic study: main goal is to identify a casual relationship  between a risk factor and an outcome Randomly selected individuals will receive a medical 
intervention or a placebo
Experimental: randomized controlled trial Observation: cross-sectional, case control, cohort study o Limits of epidemiology Biological variability among people  Control group Multifactorial causation  o Cross-sectional study 
o Cohort study 
o Case-control study
- Factors Affecting Science o Internal Factors:
