Born Too Early
739 Words - 3 Pages.... and the bad that come with having a premature infant.
When a baby is born prematurely there are a number of tests that the baby has to go through. First the doctors and nurses have to assess the baby’s heart, lungs, color and temperature. If the baby is having trouble with any of these things then it is taken into what is called the neonatal intensive care unit. In some of the smaller hospitals they aren’t equipped with the technology that is needed to keep the baby alive and the baby has to be transported to a bigger hospital, usually to a hospital in a metropolitan city in order to get the proper care. After the baby has been assessed for problems then it is watched cl ....

Cloning And Its Impact
1028 Words - 4 Pages.... agricultural industry as the technique of nuclear transfer improves (Hawley, 1998). Nuclear transfer takes the nucleus of a cell from one individual and places it in the egg or another individual, from which the nucleus has been removed (Wertz, 1998b). The change in phenotype, the observable physical and biochemical characteristics of an organism, of livestock is accomplished by bombarding embryos of livestock with genes that produce “super” livestock traits; however, this technique is not efficient because only five percent of the offspring express these “super” traits that would guarntee a more productive industry. Scientists can easily genetically alter adult ....

Prions
1715 Words - 7 Pages.... tribesmen that when they died, as a
sign of respect their brains where eaten and the chain went on and on.
The thing that makes prions so special is the fact that they lack the
basic elements for reproduction, deoxyribonucleic acid and ribonucleic acid DNA
and RNA respectively. This is what has given science a great deal of doubt as
this would give the dogma of the beginning of live a radical turn.
Prions have been in research for many years with experiments like the
one done by Stanley B. Pruiser and his team of scientists at the School of
Medicine of the University of California at San Francisco in which a study was
carried out on mice to see if he was able to purify ....

Between The Forest And Greed
916 Words - 4 Pages.... of course neglects the
fact that the reason logging generates capital is because the world needs wood.
There are several economic and environmental issues that are considered when
loggers enter and area. Haphazard clear cutting of forests, while it maybe what
Meadows would like us to think, does not happen. With every industry, every
aspect is carefully debated and analyzed for the short and long term outcomes.
Any industry that capitalizes on earth's resources figuratively signs a
pact with the earth. This pact bonds this industry to the earth and requires
that any harvesting of resources is not done so with haste and waste. There is
a symbiotic relationship betwee ....

Alzheimer’s Disease
739 Words - 3 Pages.... was a loss of nerve cells from the Cerebral Cortex in the Alzheimer's victim. Approximately ten percent of the neurons in this region were lost. But a ten percent loss is relatively minor, and cannot account for the severe impairment suffered by Alzheimer's victims. Neurofibrillary Tangles are also found in the brains of Alzheimer's victims. They are found within the cell bodies of nerve cells in the cerebral cortex, and take on the structure of a paired helix. Other diseases that have "paired helixes" include Parkinson's disease, Down's syndrome, and Dementia Pugilistica. Scientists are not sure how the paired helixes are related in these very different diseases. Neuritic Pl ....

Continental Drift
726 Words - 3 Pages.... The frictional drag along the leading edges of the drifting continents created mountains. Wegener's theory met controversy until 1954, when British geophysicists seeking to explain the phenomenon of polar wandering revived it. Since then, the modern theory of Plate Tectonics has evolved from and replaced Wegener's original thesis.
Plate Tectonics is the theory that deals with the structure, history, and dynamics of the earth's crust. The earth's crust is formed of 13 continental plates. The boundaries of the zones are where tectonic activities occur, and where earthquakes and volcanic eruptions tend to happen. The plate tectonics theory was thought up in the 1960s an ....

Stephen J. Hawking By Rachel Finck
1564 Words - 6 Pages.... reading, writing, or calculating in a
direct and simple way. The bulk of his work, involving studying, publishing,
lecturing, and worldwide travel, is carried on with the help of colleagues,
friends, and his wife. Of his illness, Hawking has said that it has enhanced
his career by giving him the freedom to think about physics and the Universe.
Stephen Hawking has written many essays involving the unified theory,
which is a theory summarizing the entire of the physical world; a theory that
would stand as a complete, consistent theory of the physical interactions that
would describe all possible observations. Our attempts at modeling physical
reality normally consists of ....

The Big Bang
1283 Words - 5 Pages.... of that early stage rapidly expanded and cooled.
Several million years later, it condensed into galaxies. The universe has
continued to expand, and the galaxies have continued moving away from each other
ever since. Today the universe is still expanding, as astronomers have observed.
The Steady State model says that the universe does not evolve or change in
time. There was no beginning in the past, nor will there be change in the
future. This model assumes the perfect cosmological principle. This principle
says that the universe is the same everywhere on the large scale, at all times.2
It maintains the same average density of matter forever.
There ar ....
