The Discovery of Dinosaur Fossils in Antarctica
While working in Antarctica, two separate research teams with hundreds of miles between them each made astounding discoveries. They discovered dinosaur fossils. Antarctica has been home to many other dinosaur fossil finds but what was so special about these fossils is that they were from an unknown species of dinosaurs. Really what the discovery compliments is that the discovery of these fossils encourages the theory of plate tectonics and continental drift. Antarctica now is a baron frozen continent with little life. 170 million years ago it was a more habitable environment because was oriented at a different location on earth. The two new species of dinosaurs were that of a meat-eater and a plant-eater. The meat-eater was found on an ancient island the used to be covered by sea and the plant-eater was discovered on the slopes of a mountain that is 13,000 feet high but probably a riverbed at the time when this dinosaur roamed the earth. This discovery not only shows how continental drift and plate tectonics helped the dinosaurs move but also the discovery of two new species of dinosaur. These discoveries will help us further our knowledge of what happened to the dinosaurs.
What the article seems to find most striking is the locale of where the dinosaur’s fossils was found. The fossils of the plant-eater date back to 170 million years ago. The scientists think that the mountain was probably a riverbed or a soft mound. It was not even close to the 13,000 feet that shoots up from the surface of earth almost touching the sky today. On the other hand the meat-eater who was found a rocky island was thought to be killed by rising seas. This dinosaur’s bones date back to about 70 million years ago. This discovery is so important to the scientific community because the plant-eating dinosaur dates back to 170 million years ago. This is when the dinosaurs first started to rule that animal kingdom. These fossils might prove to be useful in learning more about where and what the dinosaurs came from. They could figure out who they evolved from. The other dinosaur comes from around a mass extinction caused by an unknown object form space. By researching these fossils it might help us to see what happened and how the environment changed to completely wipe out the entire race of dinosaurs.
“Sex, Drugs, Disasters, and the Extinction of Dinosaurs” is written by Stephen Jay Gould, professor of geology and zoology at Harvard. This essay is one of more than a hundred articles on evolution, zoology, and paleontology published by Gould in national magazines and journals. It tells about scientific proposals for the extinction of dinosaurs – a confusing but an exciting problem that humanity tries to solve. By analyzing and describing each of the claims for the reptiles’ demise – sex, drugs, and disasters – Gould differentiates bad science from good science and explains what makes some theories silly speculations, while the other, a testable hypothesis.
There is a lot that has been said about the missionary trips of this distinguished servant of Christ which started about fourteen years after his transformation. His travels have left many Bible scholars confused about his powerful impact and how he founded of the Western Christian Church.
The question of what caused the extinction of megafauna during the Late Pleistocene period is one that archaeologists have struggled to answer for decades, but why should it matter? Discovering with certainty the cause of megafaunal extinction would simultaneously prove or disprove any of the proposed implications of each existing theory regarding this massive extinction.
...ories of why dinosaurs went extinct abound, and as there is no theory yet to be truly confirmed as the “right one”, my theory of dinosaur cannibalism is also purely anecdotal. The discovery of the cannibalistic Majungatholus atopus in Madagascar is an important scientific find because it confirms a long-standing theory of cannibalism among certain carnivorous dinosaurs. Behavioral patterns of extinct animals are difficult to establish; however, these bones give authentication to previous unfounded beliefs about the ancient feeding practices of some dinosaurs.
Of course it was the movie Jurassic Park who seemed to coin the phrase “Dino DNA.” This movie gave the public the thought that, a) it is possible to find dinosaur DNA and b) we can clone dinosaurs from this DNA. This essay is not going to pick apart Jurassic Park’s scientific value, however it will share the current knowledge and information on dinosaur DNA. The discovery of DNA is important because it may uncover different bits of information. The idea of cloning dinosaurs, especially at this point is out of the question. It is really hard to clone living animals today, with full DNA and genome strands, we can’t even think about recreating animals millions of years ago.
We use dinosaurs to represent the changes in nature that have occurred throughout time. Studies found that although the “oldest rock did not show evidence of life, the progression of plant and animal life that changed in recognizable intervals, from ancient life, age of reptiles to the age of mammals” (Dino Nature Metaphor, slide 6), measured the age of the earth. When we think of dinosaurs in relation to nature, we think of that very powerful force that controls the cycle of life. Nature was able to yield such magnificent ferocious creatures that walked the earth and then take them back when they served nature’s purpose. Dinosaurs fit perfectly in nature’s constant
This recent discovery has left scientists with many questions to be answered. The discovery is quite important because any research up until now has failed to uncover any evidence that would reveal that dinosaurs fed among their own kind. Ray Rogers whom has been leading the ten-year excavation states in the article that there are at least 14 current day animals that still practice cannibalism such as lions, komodo dragons, crocodiles, hyenas, black bears and grasshopper mice, but in contrast, any evidence of cannibalism among dinosaurs is sparse.
These penguins lived after the Castastrophic event “Cretaceuous” that demolished the dinosaurs and many other species. Based on the DNA analyses and avaiable evidence of modern birds, we think the modern bird- lineages, including penguins, some how managed to survive through the Cretaceuous. Also it’s not shocking these fossils were found in New Zeland. The South Pacific and Southern oceans were free of predatory mammals, had abundant food, and had space for Penguins to breed. But the Southern Pacific is not the only area where Penguins inhabit. Many of modern penguins “Aptrenodytes” are located in the Antarctic. Recenelty it was discovered that there was a over looked feature on the surface of the fossil penguins flipper bone. These grooves were easily missed because the look was similar to tendons and muscles in the same area. It was discovered that these grooves were blood vessels that make up a counter current heat exchanger called “humeral arterial plexus” which allows penguins to limit the heat loss through the flippers. Also it helped Penguins maintain their core body temperature in cold water allowing them to survive long journeys in the cold waters. Although Penguins have luckily been able develop these traits to survive the dramatic shifts in climate, the world population can not mistake their success as resilience towards global warming.
Many breast cancers are sensitive to the hormone estrogen. Thus estrogen leads to development of breast cancer tumor formation. Such cancers have cell surface receptors for estrogen. They are called ER-positive cancer or estrogen receptor-positive cancer.

Breast Cancer is defined as “a group of solid tumor malignancies arising in the tissues of the breast” (Sarah Crawford, Richard Alder, 2013) in human and other mammals. It can happen to both men and women. For women, breast cancer is one of the leading causes of cancer death. According to National Cancer Institute, in the United States, the 2014 estimated new cases and deaths of female from breast cancer are 232,670 and 40,000, respectively. For male, it’s 430 deaths out of 2,360 new cases. From these numbers, we can see that women in the U.S. are greatly affected by breast cancer, thus, it’s not difficult to imagine the impact on a worldwide level. Although these numbers look frightening, people can actually survive from breast cancer if it is detected early and treated properly, so it is extremely important for all of us, especially women, to have a better understanding of breast cancer.
In today’s society, one of the main diseases affecting women is breast cancer. Cancer is defined as disease in which abnormal cells divide without control and are able to invade other tissues (“What is Cancer?”). Breast cancer is most often caused by either a woman’s genetics or through the influence of lifestyle choices. Breast cancer remains one of the major concerns in the medical field, mainly because it has many forms and happens to strike a large number of women. However, over the last few decades, diagnosing and treating breast cancer has rapidly evolved and improved. As of 2013, there are more than 2.8 million breast cancer survivors in the United States (“What Are the Key…”).
Paul the Apostle, formerly known as Saul, lived much of his life preaching the Good News that Jesus brought and spreading it to the nations. Paul is a particularly notable follower of Jesus because he contributed several books to the Bible, and he reached a large number of people groups during his travels abroad. However, Paul was not always a such a saint. It is important to note that Paul was a human and had real struggles, just like us. Although he accomplished many things for the Kingdom of God, he wouldn’t have been able to do so without trusting God to work through him. In this paper I will demonstrate how God can turn a life around and what the life of a servant of the Lord looks like, with its successes and failures, through a chronology of Paul’s life.

Upon reading his letters on the accounts of Jesus, I am deeply disturbed by Paul’s numerous contradictions, jarring hypocrisies, blatant anti-Semitism, and demeaning antifeminism. Even more troubling is Paul’s consistent failure to not ever quote Jesus, but to make the recipients of his letters rely solely on the fact that God and Jesus consecrated him, Paul—according to Paul, himself (of course). Paul believes that he has been chosen, much like Abraham, Noah, Moses and the Prophets to carry out Jesus’ demands of how people should live until Jesus returns. However, unlike Abraham, Noah, Moses, and the Prophets, Paul does not dictate t...
