Ready4	<p class="ng-scope" zoompage-fontsize="14"> Finzer predicts that the possibilities for medical research could be expanded through a strategic deployment of the data-gathering and -analysis technologies now becoming available. Currently, huge amounts of data are already being generated for each patient—raising hopes for the possibility of highly personalized medicine—as well as by clinical studies and other methods that promise to allow comparison across populations. Although data storage and access present security and privacy concerns, Finzer points out that the benefits far outweigh the risks, which can be mitigated. Both local and internet-based storage solutions have been proposed for minimizing the possibility of patient data theft.p> <p class="ng-scope" zoompage-fontsize="14"> Finzer hopes not only that data will be gathered and stored but also that the medical community will recognize the need for more medically-trained data scientists to analyze the data. Often medical researchers simply employ a computer scientist with little medical knowledge to perform specific analysis-related tasks. Results produced using this method are likely to overlook important factors, correlations, or anomalies in the data. A closer collaboration between medical and data science, Finzer says, would allow researchers to fully exploit the possibilities the vast amounts of available data present by increasing understanding in the medical and data science fields of how data is organized and what it implies, respectively, allowing better collaboration on projects where the two are strongly intertwined. For example, computer modeling could speed or improve clinical trials of treatments in humans. The field of genetics also routinely employs computer models.p>

Ready4	<p class="ng-scope" zoompage-fontsize="14"> It is a counterintuitive but well-documented historical truth that the economies of the classical cultures typically seen as the progenitors of western liberalism and political freedom were all founded on the development and perpetuation of agrarian slavery. Because the cultures of antiquity are often associated with Periclean democracy and Roman republicanism—both oligarchical political systems at least nominally dedicated to principled and representative rule—students of history are often confused to learn that the populations of these societies contained large numbers of disenfranchised individuals who were often indentured to members of the middle and upper classes for a lifetime of brutal servitude.p> <p class="ng-scope" zoompage-fontsize="14"> Many historians attribute this confusion to the triumphalist mythmaking of previous generations of scholars of classical history; indeed, most interpretations of classical literature and history have been distorted, but one would nonetheless expect modern revisionism and understanding of the concept of presentism to provide balance.p> <p class="ng-scope" zoompage-fontsize="14"> Historians note that there is little discussion of slavery or its moral significance within classical sources, seemingly because individuals in the classical period saw it as both an economic necessity and inherent to the world's natural order. They cite the example of the writer Heraclitus (535 B.C.E.–475 B.C.E.), a pre-Socratic philosopher. Heraclitus is known as the “Weeping Philosopher,” and he was among the most incisive thinkers working in antiquity but, even so, the omnipresent institution of slavery struck him as an immutable element of human affairs; he wrote that “War is the father of all, the king of all … he turns some into slaves and sets others free,” implying that slavery is beyond the power of political determination—and beyond intellectual moralizing. Heraclitus is not alone in his failure to question the moral underpinnings of a slave society. Aristotle, too, suggested that the taking and keeping of slaves was a component of natural law, a fundamental consequence of military activity rather than a conscious policy that could be actively perpetuated or proscribed by the laws of man. In promoting this view, though, Aristotle demonstrates an unusual degree of circumspection, wondering whether the taking of slaves could be justified if the war in which they were acquired was itself “unjust.” The figures of early modernity saw themselves as heirs to the classical tradition and inherited the Greek and Roman attitudes toward slavery and citizenship as well as their commitments to democracy and rational inquiry, and modern historians have, in their studies of these times, endeavored to avoid the interpretive trap of imposing their modern ethics on the people of ancient times.p>

Ready4	<p class="ng-scope"> As understandings of the solar life cycle developed, scientists were confronted by a nagging question: If, early in the history of Earth's planetary formation, the sun was significantly dimmer than it is now, how do we explain evidence for the presence of liquid water on the planet's surface during this period? It is understood that during the early Earth period our sun would have shone at about 70 percent of its current luminosity, significantly below the level necessary to sustain the presence of liquid oceans on the planet's surface. But paleontological and geological records indicate with substantial certainty that liquid water was present on the Earth's surface during this time. If scientific models of solar development and the early geological history of Earth are to be reconciled, there must have been some other, intervening factor affecting surface temperatures during this early period of geologic history.p> <p class="ng-scope"> Our method of reconciling these two apparently contradictory bodies of evidence has been to analyze the characteristics and chemical composition of Earth's atmosphere during its various periods of geological development. We have known for decades that the presence of certain vapors in the air, commonly known as “greenhouse gases,” increases the amounts of heat retained by an atmosphere to a degree proportionate to the concentration of greenhouse gases within it. If the Earth was warmer in the past than solar luminosity would suggest—and we have strong evidence that it was—then we can expect that the distribution of greenhouse gases in its atmosphere would be of paramount value in explaining that discrepancy. Heightened greenhouse gas levels would trap and magnify the sun's heat as it struck the atmosphere, enabling liquid water to exist on the surface of Earth. However, we have discovered little evidence that greenhouse gases during the early Earth period were present in larger quantities than previously assumed. These surprising findings indicate that the discrepancy between solar-astronomical and geological evidence related to the development of Earth's oceans cannot be explained by the presence of carbon in the atmosphere.p> <p class="ng-scope"> One likely alternative is that another, non-solar source for atmospheric heat during the early Earth period. Earth and its moon were much closer together in the early geologic history of the planet, and tidal heating caused by the moon's rotation around Earth was likely much greater. While it is unclear how much influence this phenomenon might have exerted over atmospheric temperatures, scientists are increasingly convinced that it could play a part in explaining the unlikely presence of liquid water on our infant planet, perhaps in combination with indeterminate geological activity, solar flares, or irregularities in Earth's magnetic field.p>

Ready4	<p>The origin of life remains one of the world's greatest mysteries even to this day. Several theories have attempted to explain this phenomenon, but thus far, there has been no conclusive evidence to support one theory over another. One of the most popular theories is the primordial soup theory. This model purports that all life on the planet was created out of a “primordial soup." Oparin and Haldane, the scientists who developed this model, hypothesized that all life forms originated in a warm pond or ocean from a combination of chemicals that created amino acids. All the building blocks of life were already available in the atmosphere. These molecules were then “energized” by lightning, and combined to form amino acids which, in turn, folded into complex proteins. The first organisms to evolve were simple heterotrophs, which survived by consuming other organisms. Theoretically, this is plausible. Miller and Urey, in 1950, carried out a rather famous experiment to test this theory. They mixed gases believed to have been present in the primordial atmosphere and then energized the mixture with an electric spark. They discovered that all 20 amino acids could be produced in this manner. p><p>However, there are several major flaws in this theory. First, the formation of proteins from amino acids is an extremely complex process. There are over a trillion ways amino acids can combine to form proteins, and hitting upon the right protein by accident is extremely improbable. Moreover, the primordial soup would have been way too diluted to achieve anything. In short, there is just too much left to chance. As one critic put it, “What are the chances that a monkey playing with an old typewriter will accidentally type out a bestseller?” An alternative theory is that life originated deep underground, not in a water body. One could argue that “superbugs," which are present in deep soil even today, were the first life forms to evolve. They may have originated as microbes thriving on intense heat. However, there has been no satisfactory account of how these superbugs evolved from a mass of chemical compounds. p><p>Another hypothesis is that life did not originate on the earth at all. The Panspermia theory suggests that life seeds came from outer space. This theory has found considerable support, as it explains the sudden spurt in life forms after millions of years of nothingness. Also, statistics show that 7.5% of rocks from Mars reach earth. Such rocks, from Mars or elsewhere, could have transported bacteria, which can easily survive the harsh environs of space. After all, there is evidence that meteorites contain amino acids and bacteria. Panspermia states that these meteorites carried bacteria, amino acids, methane and carbon. These substances were then deposited on earth, either in warm oceans or underground, and eventually grew into simple life forms. This theory merits further research because it has potential to explain not only the origin of life on earth, but also prove the presence of life beyond the earth.p>
