Although there have been many possible contributors to establishment of what is often called "advanced science," the ideas of the philosopher Rene Descartes are vital to science but especially to psychology. Descartes lived from 1596 to 1650, and usually wanted to find answers to the questions like Are the mind and body the same, or different?" His answers were started to be called as Cartesian Dualism, this concept say that mind and body are two different entities, but that the mind can influence the body and the body can influence the mind. So to research on this idea the church and the scientist divided the work among them. The church could still work to influence the mind of individuals, and the scientists of the day could study the body, each group having its own domain to some
To conclude hybridisation played a role in shaping the evolutionary history of modern humans but only to an extent. The modern humans gained many beneficial traits to help them as they explored into new environments - and may not have survived without the help of the hybridisation. On the other hand, there is not enough fossil evidence of the interbreeding between species, which could suggest that the two species did not interbreed often or when they did interbreed they did not produce
Through studying MS, researchers are finding ways to better protect our Myelin against attacks such as through a process called remyelination. Recent studies have led many scientists to believe that CD8+ T cells, whose job is to protect good cells and kill dangerous ones, play a role in the myelin damage. However, more research is needed to learn more about MS and what causes it. Not all studies agree that DD8+ cells cause the attacks, but instead some think that they tone down the attacks. Overall, there is many answers for scientists to find.
To further his work he himself, with the help of graduates and a couple of undergraduates, work extensively researching different parts of the nervous system. So, even though he has taught several different classes such as gender studies, genetics, introduction to molecular biology and neuroscience his research has always remained his passion. He even wanted to be a doctor at one point, but decided against it as he did not enjoy it; however, he did enjoy being a part of a lab environment researching about the
It was the recent documentary Blackfish that helped spark my interest in neuroscience. A neuroscientist (Dr. Lori Marino) and her team had, upon taking an MRI scan of an orca's brain, discovered an unusual extra lobe sat adjacent to the Limbic system. They were uncertain as to the function of the lobe but it was thought that it could have been used to process emotion or even aid the process of thought. It was then revealed that other mammals (even humans) had failed to develop this part of the brain. I was intrigued by the parallels that could be drawn between us as a species and our fellow mammals (neurologically speaking) and so began to dig deeper into the area of study.
Throughout this lab many things were concluded about cells, organelles and biology all together. A biologist needs to be patient, careful and accurate. In addition when looking at cells, to see all the organelles, being careful will help significantly and being patient will make it easier to see the cells on a high power lens. One thing that was concluded in both experiments is that in each different organism and cell there was a different quantity of organelle unlike the diagrams in the textbook. The last thing that was concluded is that no two organisms are the same.
According to The Gospel Coalition the “intermixing of genetic material becomes more morally problematic” because few believe that it “violates the species barrier instituted by our Creator”. While others consider the uses of chimeras “morally legitimate” (Carter). However, chimeras are being created so that they “can be used to transplant organs into people who are in need of them.” Chimeras are also used as a model to study how human diseases happen and how they progress. Chimeras are being used to create “life saving organs and potential treatments for debilitating disease” (Imam). Furthermore, the creation of chimeras also connects to the ethical controversy in Mary Shelley’s Frankenstein.
These cells are known as HeLa. HeLa cells contributed lots of scientific knowledge, but were also a curse to the Lacks family. Key Idea 1: The Anatomy of Cells Today, science textbooks everywhere are filled with the anatomy and structure of cells. We can credit much of this knowledge to HeLa. HeLa cells have allowed scientists to study cells in a more detailed way and gather information about cells impossible before HeLa.
How should the term "aging" be defined? Biological sciences and social sciences have different views on this, and form a variety of different definitions. Edmund cowdry (1942), one of the founders of senile biology, argues that aging can be seen both as an endogenous process and as an exogenous process . In the biological endogenous view, the aging is not a personal will for the transfer, but because of the passage of time led to changes in the direction of the cells to the adverse changes, this adverse changes continue to accumulate the final performance of aging; Aging is due to infection, accidents or damage to toxic substances in the external environment. Biological science in the interpretation of the biological basis of aging, some
Living in the twenty-first century, conducting a multitude of experiments without using animals to derive better results more quickly and at less cost is more probable to occur than it would have decades ago. New, cutting-edge technology such as the use of lasers, fiber optics, microchips, genomics, computer-based drug design, and digital imaging have created new opportunities for research. These new methods have contributed to a technological revolution in product testing and research. The new technological strategies have made the reliance on animals to be outdated; however, scientists have only just begun to use these new technologies. The new and updated modifications to animal testing may never reach its full potential if the dependence on animal models continues.
