UFO Sightings
.... to carefully evaluate UFO reports to extract
information about unusual phenomena currently unknown to science," the
report stated, adding that such research could also improve understanding
of, and in some cases debunk, supposed UFO events.
For example, Earth science researchers have eventually accepted several
phenomena "originally dismissed as folk tales," including meteorites and
certain types of lightning, the panel noted.
The findings are from a four-day workshop held in Tarrytown, N.Y., followed

The Element Carbon And Its Importance
.... and
ivory black, made by heating ivory, is used as a pigment in paint.
Most carbon occurs in combination with other elements. For example,
the carbon dioxide in the air is a compound of carbon and oxygen. Other
compounds containing carbon include minerals such as limestone, and fuels
such as coal and petroleum. Carbon compounds make up the living tissues of
all animals and plants. There are over one million known carbon compounds
(still growing rapidly every year), which is over the sum total .....

Aluminum: The Element
.... It is never found
as a non-metal. It occurs most commonly as aluminum silicate or as a
silicate of aluminum mixed with other metals such as sodium, potassium,
iron, calcium, and magnesium. Charles M. Hall and Paul L. T. Heroult,
independently and almost simultaneously found out that alumna, or aluminum
oxide, would dissolve in fused cryolite (Na3AlF6) and then could be
decomposed electronically into a crude molten metal.
Uses-
The given volume of aluminum weighs less than one-third than steel. Its

Deforestation In The Brazilian Amazon
.... the
country is still losing more rain forest each year than any other on the
planet. Brazilian forests are burned or felled at the rate of 1800
hectares (about 4500 acres) every hour! (Dwyer 39) Deforestation started
hundreds of years ago, but only became a major problem in the second half
of this century, when it increased dramatically. It was enhanced by the
Brazilian government which started cutting down the forest to construct a
vast network of highways in an effort to establish a good transporta .....

Forests Cannot Absorb CO2 Emissions
.... stored in vegetation and forest soils. This will add further to
the climate change problem. Experts hope that this new way to cut back on
these CO2 emissions will not be costly and time consuming.
Dry air is made up of about 78 percent nitrogen and 21 percent
oxygen. For living things, the two most important gases are oxygen and
carbon dioxide. All plants and animals in respiration use oxygen.
Respiration is the process by which food is changed to energy.
Photosynthesis is the process by wh .....

Crystals: Does Surface Tension Affect The Process Of Crystallization?
.... or are not perfect, then the formation of the crystal will be
disturbed. One may ask him/herself, how is the formation disturbed if only
one of the condition would happen to be modified? Most crystals are formed
under water or under liquids with similar characters to water; and tend to
form under liquids or solutions containing a maximum amount of solute. If
the liquid absorbs additional solute, then the solution is supersaturated.
If a tiny crystal, called a seed crystal, is added to the substance, a .....

Experiment To See If Soaking A Golf Ball Affects Its Distance
.... until it got wet. Then it would split open. The
Gutta percha was introduced in 1850 and was made of a rubberlike sap from
the Malaysian sapdilla tree. The material was heated to soften it and then
hand-formed into a solid, one piece ball.Gutta percha was black, so the
early balls were painted white. Easier to make, less expensive, and more
durable, the gutta revolutionized golf. When golfers discovered that balls
and nicks flew longer and straighter then new ones, manufactures began to
give them a tex .....

Victor Frankenstein And His Use Of Science
.... of life is the
existence of God and that God created the earth and all of the life on
earth.
Victor Frankenstein is exactly like the scientists of today.
Victor Frankenstein is trying to make a human being from other, deceased
human beings, this could be compared to cloning today, making one creature
from another. The possibility, or theory of genetic engineering can
guarantee that humans would be without deformity, affliction or frailty.
Victor Frankenstein may not have chosen parts for his mon .....

White Shark: Summary
.... They
ended up diving right down to the steel boxes that contained the "White
Sharks". The men were curious and so they opened the box. Nothing
happened at first and then glowing eyes caught their 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 we .....

Genetic Engineering: Correcting The Code

way to create good quality foods, create new lives, and cure diseases.
In May of 1994, the Food and Drug Administration approved a
genetically engineered tomato called “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 (H .....

Our Solar System At A Glance

and to other planets.
The United States has sent automated spacecraft, then human-crewed
expeditions, to explore the Moon. Our automated machines 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 electroni .....

Lithium found in the oceans. Traces are found in seawater plants and
animal organisms. Very small traces of Rubidium are found in the leaves 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, .....

Solving The Mystery Of The Romanovs

polymorphisms in the cells cytoplasm, during fertilization, mitochondria
are only passed on from the egg. This means that the mitochondria DNA is
passed 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 .....

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 are observational evidences found that can prove the Big Bang
model is more reasonable than the Steady State .....

The Dangers Of Nuclear "Progress"

proposing the Baruch Plan in the United Nations. This proposal stated that
all nuclear technology and materials be placed under international
ownership and that all nuclear weapons be destroyed. 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 safet .....
