Essays on Experimental Evidence

In spite of the significant advancement in science and technology, the science behind lifespan is still a mystery. The theories that explain the process of aging and life span, are broadly divided into programmed and error theories (Jin, 2010). Though none of these theories are completely satisfactory, they do help to enhance one’s understanding in the area. According to the programmed longevity theory, aging follows a biological timetable, which is innate and heritable. The theory was first suggested by August Weismann. He theorized that; there is an actual limit to the extent of somatic cell division in a species, and this is ...

- Abstract Cardiovascular diseases such as heart failure are some of the leading causes of mortality and morbidity with Australia being one of the country’s most greatly affected (McLean, Esclick & Coats, 2006). An area of interest in the pathology of heart failure is the significance that polymorphisms of adrenergic receptor genes have on the outcomes of patients with heart failure. Single-nucleotide polymorphisms or SNPs that occur in the genes that encode for adrenergic receptors are known to have various physiological and functional consequences. Specifically, the β1-adrenergic receptors have a crucial role in the regulation of heart rate and ...

The article entitled “The Difference Between Men and Women, Revisited: It’s About Competition” is a discussion written by Prof. Hal Varian on his views about the difference between men and women with reference to the paper written by two economists, namely Muriel Nierderle (of Stanford University) and Lise Vesterlund (of University of Pittsburgh) entitled “Do Women Shy Away From Competition? Do Men Compete Too Much?.” Prof. Varian recognized the attempt of the two economists to explore, through an experiment, the gender differences of which the findings, according to him, “have certainly raised a host of interesting and important questions.” In ...
