The Basic Steps in Creating a Genetically Modified Organism (GMO)
A genetically modified organism (GMO) is a plant, animal, or microorganism whose DNA has been modified or altered through genetic engineering (Lallanilla, 2016). GMOs and modification to an organism's genetic material is not natural is any way and does not occur from mating or natural recombination (World Health Organization, 2016). Genetically modified organisms are created by means known as "modern biotechnology" or "recombinant DNA technology" which allows selected individual genes to be transferred from one organism to another even between…...

The Safety and Impact of the Use of Genetically Modified Organisms (GMOs)
The use of genetically modified organisms (GMOs) has been on the rise since its invention in 1996. It is estimated that upwards of 75% of foods in the United States' food supply contain genetically modified ingredients (Gruere and Rao 3). Although many studies have been done, there has been no consensus from the scientific community on the long term impact of GMOs. This has been a cause for concern for many Americans due to possible impacts on human health. However,…...

An Examination of the Health Risks of Genetically Modified Organisms (GMOs)
Genetically modified organisms (GMO's), are ‘organisms whose genetic structure has been altered by incorporating a gene that will express a desirable trait, often termed gene splicing. Most often, the transferred gene allows the organism to express a trait that would add to its desirability to both producers and consumers of the end product'. The genetic engineering of foods, which is 'the science that involves the deliberate modification of the genetic material of plants and animals' (Uzogara, 2000), has adverse on…...

The Symbolism of a House in There Will Come Soft Rains by Ray Bradburry
In Ray Bradbury’s “There Will Come Soft Rains," the personification of the house, the uses of medical and psychoanalytic discourses, and ritualistic constructions in the text, revolving around religious discourse frame the house and nature as opposing forces. Through the language of the text, the house is diagnosed as a machine with two sides: the caring, domestic, automated home and the whirring, incinerating, cold-eyed machine. Nature spites the house for continuing its empty and pointless rituals without humans inhabiting the…...

Neanderthal Beliefs: Evolution vs Creationism
Homo neanderthalensis is known as the closest extinct relative to modern humans. Their physical appearance was very similar to Homo sapiens except they had larger sculls and flatter faces. They engaged in many human behaviors such as using tools, living in shelters, wearing clothes, and burying their dead. There are two varying viewpoints about how Homo neanderthalensis fossils fit into the fossil record in relation to modern humans. The evolutionist view holds that modern humans may have evolved out of…...

Tech and Human Evolution Meet with Computers?
The human kind is known as the most intelligent form of life on the Earth. What makes us so superior over the rest of the species? Some may argue, but I think that it is our ability to think in abstract. Abstract thought couples with our drive to evolve, and create better and more sophisticated things, which in terms explain humans progress throughout their existence. Our progress, however, is based on a few fundamental discoveries and innovations, which were subsequently…...

The Role of Emotions, Cooperation, and Social Relationships in Human Evolution
Emotions are complex psycho-physiological experiences of an individual's state of mind while interacting with internal and environmental influences. Simply put, emotions are a reaction to internal and external stimuli. While humans express emotions with words most often, non human primates don't have that luxury. Primates express emotion with facial expressions, postures, grunts, and other physical means. And of course, humans do these things also. The most obvious displays of emotion are caused by another individual's behavior, like when someone irritates…...

A Study on Human Evolution and How Humans are Able to Detect Animals
It is widely theorized that, throughout the longitudinal evolutionary history as hunter-gatherers, the human species developed sophisticated mechanisms of animal detection. One of these mechanisms geared towards animal detection is so called "kin recognition," by which various species of animals, including the human species, respond more quickly and adroitly to the traces of other animals that are phylogenetically closer to themselves. It is also dealt with, in this study, how the human species developed a way to respond differently to…...

The Many Ecosystem Services
The diversity of soil bacterial communities is immense and provides a variety of ecosystem services. Functions constituting the vast biodiversity of soil bacteria include bioremediation, nitrogen fixation, and the production of antibiotic metabolites. Serving as an approach to remove soil contaminants, bioremediation is an important function of soil bacteria. The contamination of pollutants, such as oil spills, creates toxicity on soil ecosystems. Albeit pollutants produce a destructive impact, bioremediation transforms perilous materials into benign compounds utilizing microorganisms. Although toxins can…...

Combining Genetically Modified Crops with Existing Agricultural Technologies
The world's population, growing now to a predicted number of nine billion by 2050, must have sufficient nutrition to avoid disastrous social consequences. Mass starvation is the first of these possibilities as currently. "Ten children die of starvation per minute” (Jacobsen. et al., 2013). Another easily foreseeable issue is large scale anarchy and social chaos resulting from millions of people desperate for food. These dire predictions will be exacerbated if the more disastrous effects, including more frequent heat waves, floods,…...

Mammary Glands and Their Role in Feeding
Mammary glands are glands located in the breasts of females that are responsible for lactating, or milk production. Both males and females have glandular tissue within the breasts. However, after puberty, the glandular tissue begins to develop in response to estrogen release in females. Mammary glands only produce milk after childbirth. Various hormones, such as oxytocin and prolactin, have a role in the production of milk. Oxytocin is produced in the hypothalamus and is secreted into the bloodstream by the…...

Yes, if we did not have it or if it is broken, fractured, sprained, etc, life can be a little difficult. The ankle is a very important tool in the art of walking, running, even standing. The average ankle consists of bones such as the Talus and Calcaneus. The thickened portion of the fibula called the medial malleolus forms the ankle joint or talocrural joint sometimes- called ankle mortise. The ankle joint allows two motions: plantarflexion and dorsiflexion. Stretching, strengthening…...

The Contrasting Ideas of Paracelsus and Vesalius on the Concepts of Anatomy
In the early to late 16th century, the writings of Paracelsus and the Galenists, namely Andreas Vesalius, gave the impression that they inhabited very different intellectual worlds with very different, and sometimes opposing, ideas about how the human body works, how one goes about studying it, and how one goes about healing it. One concept on which Paracelsus and Vesalius had almost completely contrasting ideas on was "anatomy". The intellectual rift separating the medicine of Paracelsus from that of Vesalius…...
