White Shark: Summary
.... attention. One guy
was killed. The other guy managed to get away and swim for about 200 yards
and then he was down. The men's bodies washed up on shored weeks later.
That's when Chase and Tall Man knew there was something in the water and it
was up to them to figure out what it was. More strange things were
happening. The ocean life began to act strange and Chase couldn't figure
out what that had anything to do with the killings.
Tall Man was a rather large Indian man that had many reasons to be
fearless. The reason I'm drawing attention to this man is because he is
the hero. After all the hard work and long hours o .....

Genetic Engineering: Correcting The Code
.... “Flavr Savr”. Many people cringe at
the thought of eating them. These tomatoes, though, are proven better and
healthier even though they are slow ripening. The idea of altering a
plant's traits seems radical and new, but scientists have been doing it for
years by breeding desired qualities into crops (Henkel 10). “Subsequently,
seven vegetables were brought to market under the Pre-Market Notification,
PostMarket Authority approach that will govern the introduction of the new
food type” (Henkel 9).
Some exceptions are made when a gene from a potentially allergenic
food , like peanuts, is transferred into another food, or if .....

Our Solar System At A Glance
.... have orbited and
landed on Venus and Mars; explored the Sun's environment; observed comets,
and made close-range surveys while flying past Mercury, Jupiter, Saturn,
Uranus and Neptune.
These travelers brought a quantum leap in our knowledge and
understanding of the solar system. Through the electronic sight and other
"senses" of our automated spacecraft, color and complexion have been given
to worlds that for centuries appeared to Earth-bound eyes as fuzzy disks
or indistinct points of light. And dozens of previously unknown objects
have been discovered.
Future historians will likely view these pioneering flights th .....

Rubidium
.... of
tobacco, tea, and coffee, as well as some other plants. Rubidium is
similar to lithium and cesium, which are found in combined forms as complex
minerals. It is not found in a pure elemental (metallic) state in nature,
but only as compounds in mineral deposits such as pollucite, carnallite,
lepidolite, leucite, and zinnwaldite, in addition to mineral springs. These
various minerals are found in the United States in California, South Dakota,
New Mexico, and Maine. There are 17 known Isotopes of Rubidium. The only 2
naturally-occurring isotopes are Rb85 and Rb87. Rubidium-87 is present to
the extent of 27.85% in natural ru .....

Solving The Mystery Of The Romanovs
.... on from the mother. This information becomes useful when using them
for identification purposes.
In any given cell, there are thousands of copies of mitochondrial
DNA. This relative abundance of mitochondrial DNA can be used by
scientists to obtain DNA from samples where genomic DNA analysis is
difficult of impossible. The first question was which, if any, of the
bones found belonged to the Czar. To answer this, mitochondrial DNA was
obtained eight adult male femur bones found in the grave. Then using a
program called ClustalW, the mitochondrial DNA from many of the Czar's
maternal relatives were compared to the bones. It wa .....

The Beginning Of The Universe
.... 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 are observational evidences found that can prove the Big Bang
model is more reasonable than the Steady State model. First, the redshifts
of distant galaxies. Redshift is a Doppler effect which states that if a
galaxy is moving away, the spectral line of that galaxy observed will have
a shift to the red end. The faster the galaxy moves, the more shift it has.
If the galaxy is moving closer, the spectral line will show a blue shift.

The Dangers Of Nuclear "Progress"
.... However, the Soviet
Union feared that the United States would always have a military advantage
if they gave up their plans for building a nuclear device and, therefore,
rejected the proposal.
I think that the refusal of the Soviet Union was a big mistake on
their part. Not only did they put the safety of the U.S.S.R on the line,
but of the whole world, as well. By rejecting that proposal, other
countries would soon follow America's example, producing nuclear weapons of
their own. By 1952, the Soviet Union and Great Britain had produced and
exploded their first nuclear weapons, and nuclear technology was spreading
across .....

An Experiment In Edge Damage
.... medium pressure was used on the flake and it was moved
in bi-directional strokes across the stick. After about thirty strokes,
the use edge angle prohibited the flake from cutting further in to the
stick. The cut was roughly three millimeters deep and three quarters
millimeters wide. It could be determined that a tool, in this particular
shape, could not be used as an effective saw. However, use-wear patterns
could still be inferred. The flake was moved to another portion of the
stick and the same process was repeated. This time the cut was only about
two millimeters deep, before termination. Also, small pieces of obsidian

Radon
.... radioisotope is a naturally or
artificially created isotope having an unstable nucleus that decays,
letting off alpha, beta, gamma rays until stability is reached (The America
Heritage Dictionary of the English Language, Third Edition, 1992). Radon's
melting point is -71°C. The boiling point is -61.8°C. Radon is the densest
gas known (Concise Columbia Encyclopedia, 1995).
Radon is a heavy, colorless, odorless, tasteless, non-flammable gas
(therefore it cannot be detected with the human senses) produced by the
radioactive decay of radium, which is itself a product of uranium.
Radioactive means the emission or transmission of ener .....

The Science Of Cloning
.... will be too, so they can gain support from voters.
Even with all these setbacks, there are still major uses for cloning
research. Uses that will never present themselves unless people put down
their moral, ethical, and religious shields and allow the research to take
its course. Regardless of the majority opinion, cloning is just another
science. It deserves the time and mind straining efforts given by today's
scientists. It doesn't deserve to be shut out or pushed aside because
people are too paranoid to let the future take its course.
Cloning has been around for several years. It has just recently
hit the spotli .....

The Sun

Composition of the Sun
The radiation that Earth receives from the sun is quite remarkable.
The radiation that we receive varies less than 1% over a period of twenty
four hours. However this less than one billionth of the radiation given
off by the sun. This energy comes from deep with in the sun. The
composition of the sun consists of 71percent hydrogen, 27 percent helium,
and 2 percent of other heavier elements. This makes the sun, like others,
very volatile
At the center of the sun we find the density of the sun to be more

Uranium: Nuclear Friend Or Nuclear Foe
.... scientific knowledge the doctors could only
assume that the deaths were caused by the inhalation of arsenic. Later
studies between 1900 and 1940 found that the deaths were caused by
radiation in the mines.
The radiation the miners were exposed to would later be identified
as uranium. Uranium is a natural occurring element, it has a atomic count
of 92. Uranium is easily identified by its properties. Uranium melts at
about 1132°C, boils at about 3818°C, and has a specific gravity of 19.05 at
25°C. Uranium has three crystalline forms, of which the one that forms at
about 770°C is malleable and ductile. Uranium is soluble in hydroc .....
