Ebola Virus

... was really Ebola.
The first recorded outbreak of the Zaire string of the Ebola virus was in Zaire, in 1976. The doctors didn't know how to treat it and that meant that
they didn't know how to contain it either. As infected people met in public places the virus spread. In Western Sudan, the same year, the Sudan string
of the Ebola virus emerged with similar results. Both casts together had about a total of 550 infections and around 340 deaths (about 60% death rate).
The virus' then lay dormant till 1979, when Sudan was again hit with 34 infections and 22 deaths. In the outbreak, as before, t ...

Cloning

... and standard genetic testing would be used to detect whether or not that
embryo contained the genetic disease. If this cloned embryo containd a disease
then one of the other embryos could be used for implantation in a parent, this
guarantees that the child would be free of genetic disease (Marshall 1025). For
those who disagree with cloning I am sure if there child could be saved from a
genetic disease they would reconsider cloning.
Imagine if one of your friends or family members was in need of a liver
or kidney. Most likely you would donate your own liver or kidney to save there
life. But then ...

Origin Of The Solar System

... or monistic. A common feature of dualistic theories is that
another star once passed close to the Sun, and tidal perturbations between
the two stars drew out filaments of gas from which the planets condensed.
Theories of this type encounter enormous difficulties in trying to account
for modern information about the solar system, and they have generally been
discarded. By contrast, monistic theories envisage a disk of gas and dust,
called the primitive solar nebula, that formed around the Sun. Many of
these theories speculate that the Sun and the planets formed together from
the primeval ...

... Deaths and injuries to livestock and other animals, thousands of forest and brush fires, as well as millions of dollars in damage to buildings, communications systems, power lines, and electrical systems are also the result of lightning. Finally, the threat of lightning causes many work stoppages and lost production increasing the time and cost required to
prepare NASA spacecraft for flight.
Benjamin Franklin performed the first systematic, scientific study of lightning during the second half of the 18th century. Prior to that time, electrical science had developed to the point where positive a ...

... audience, authors substitute in less complex vocabulary words, summarize difficult concepts, and often utilize attractive visual aids. Authors strive to communicate issues to audiences of varying levels of education. In order to accomplish this effectively, authors adapt their work in a format that expresses their concepts to audiences in pragmatic fashion. However, a disadvantage is that these adaptations can lead to misinterpretations of information.
Attached is a newspaper article I obtained through the web but was printed in the "Discoveries" section of The Dallas Morning News on September 14, ...

... it
protects vital organs like the brain], serves as a complex lever system,
acts as a storage area for calcium which is vital for human metabolism,
houses the bone marrow within its mid cavity and to top it all it is
capable of changing its architecture and mass in response to outside and
inner stress. It is this dynamic remodeling of bone which is of primary
interest in microgravity. To feel the impact of this dynamicity it should
be noted that a bone remodeling unit [a coupled phenomena of bone
reabsorption and bone formation]is initiated and another finished about
every ten seconds in ...

Galileo And Newton

... shapes,
numbers, and motion which are all properties that lend themselves to support
through "reasoning back and forth between theory and experiment." I feel that
Galileo's argument is a valid one because it explains relations in nature and
the physical world through mathematical analysis. This allows him to define a
world outside of human existence that can be logically calculated and explained.
His view describes the world in which living creatures live and not contrasts it
to the world within living creatures. The problem with Galileo's view is that
it pioneers a scientific outlook but never ac ...

The Destruction Of The Ozone Layer
Number of Words: 765 / Number of Pages: 3
... monoxide is an ozone destroyer. There is always a certain
amount of chlorine monoxide in the atmosphere.
It is important to remember that ozone is constantly being created and
destroyed in the atmosphere. The amount of ozone in the atmosphere is based
on these reactions. There are many factors that influence the amount of
reactions like season, latitude, and solar cycle. Because of these factors
ozone can vary wildly each day. In the northern latitudes there can be up
to 40% difference than the day before. And in the equator regions, there
might be no variance at all.
Unfortunately, the Congr ...
