Flooding
Words: 3318 / Pages: 13 .... and many local planners see coastal erosion and as a serious issue but previously viewed the concept of sea level rise as a codeword for “retreat,” giving up protective measures for the barrier island communities.There has been polarization in the past between some mayors and public officials who favor public expenditures to hold back the sea and other public officials and some scientists who are skeptical about erosion-fighting programs. There were those who believed people should not be allowed to rebuild in hazardous areas and those who would not forbid them to build as long as they did not ask for recompense when they got int .....

B E C: The New Phase Of Matter
Words: 383 / Pages: 2 .... on the cover shows the Bose-Einstien
condensation, where the atom's velocities peak at close to zero velocity, and
the atoms slowly emerge from the condensate. The atoms were slowed to the low
velocity by using laser beams. The hardware needed to create the BEC is a
bargain at $50,000 to $1000,000 which makes it accessible to physics labs around
the world.
The next step is to test the new phase of matter. We do not know yet if
it absorbs, reflects,or refracts light. BEC is related to superconductivity and
may unlock some mysteries of why some minerals are able to conduct electricity
without resistance. The asymmetrical pattern of BEC is is thoug .....

Lichens
Words: 571 / Pages: 3 .... grow farther north and south than most plants, as well as higher on mountains. One unusual type grows completely submerged in the cold coastal waters of Antarctica. Some inhabit the Earth's driest deserts, where they grow almost entirely underground and obtain light and moisture through small openings in the ground. Few grow near cities because most cannot survive in industrial air pollution. There are notable exceptions, however: in England, for example, Lecanora conizaeoides is actually confined to areas of high pollution.
The body of the lichen, the thallus, has three basic growth forms. These forms are crustose, foliose, and fruticose. Each f .....

Man-of-War
Words: 550 / Pages: 2 .... wind, and move the man-of-war along. Below the bladder, hang long
stringy tentacles, that can reach a length of up to fifty meters. The tentacles
are made-up of three different types of polyps. The names of these three polyps
are: dactylozooid, gonozooid, and gastrozooid. The polyps are the parts that:
capture prey, digest prey, and reproduce. The dactylozooids have cells called
nematocysts(3). The nematocysts release a toxin(4) into anything that they come
into contact with. The gastrozooids then attach to the dead/stunned victim, and
spread over it. They digest it, and transfer food to the rest of the man-of-war.
Last, the gonozooids create other .....

Mass And Science
Words: 690 / Pages: 3 .... Matter is anything that has mass and takes up space. Most matter on earth exists in three states: liquids, solids, and gas. All matter is made up of tiny particles called atoms. An atom is the smallest unit of matter that can exist and still be recognized. You and all the things around you are made of matter.
Since we all live at the surface of the earth where the acceleration of gravity is relatively constant, it has been natural for us to confuse the concepts of mass and weight. To study the difference, we need to separate these two "parameters." We could either leave the earth's gravitational field so that we would have no weight, or create an expe .....

A Massive Project For The Benefit Of Mankind: A Look At The Human Genome Project
Words: 1421 / Pages: 6 .... cost $3 billion
in U.S. money for the entire project coming to roughly $200 million per year.
Federal funding for the project is nearly 60% of the annual need. This has
created some funding problems for the project. There also have been
technological advances and discoveries that have helped to speed up the project.
This automation may help to reduce the cost and help the project to meet its
objectives ahead of schedule. The project was estimated to have detailed maps
of all of the chromosomes and know the location of most of the human Genes by
1996. Researchers have successfully located the gene and DNA sequence for
Huntington’s Disease on Chr .....

Technology And Education
Words: 1308 / Pages: 5 .... the development of productivity, increased student involvement and enabled students to complete joint projects with students in other cities, states and even countries (Carey 26). Studies on students who have twenty four hour access to laptops have shown that students shown an increase in problem-solving and critical thing sills, enhanced learning in core academic subjects, produce higher quality work and have even provided more one-on one time between teachers and students (THE Journal 16).
Technology is an integral component of learning. Being that students learn at different rates, technology can individualize instruction. They can mo .....

Genetic Engineering: Correcting The Code
Words: 1116 / Pages: 5 .... genetic
engineering. They could end up with a cure a lot faster and find easier
ways of getting treatment to healthier foods. From this kind of example,
genetic engineering should be a known and accepted practice. It is a safe
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 .....

Clinical Depression 2
Words: 599 / Pages: 3 .... made up of a complex network of nerve cells, called neurons and of brain chemicals, called neurotransmitters. Neurotransmitters transmit messages from one neuron to another. Two of these neurotransmitters are not produced in sufficient quantities in a depressed person’s brain. Because of this lack, too few messages get transmitted between neurons and the symptoms of depression occur. In Clinical depression the chemicals in the brain are out-of-balance. New technology allows researchers to take pictures of the brain that show activity levels in the brain. These imaging techniques such as f-MRI and PET scan actually create images of how active diff .....

The Race To The Moon
Words: 3490 / Pages: 13 .... and only the military space programs were secret. Civilian space activities, especially , were openly publicized for the world to see. On the other hand, in the Soviet Union all space programs blended into a secretive military-industrial bureaucracy. Launches were not announced in advance, and only the successes were publicized. (Baker 158-161).
During the early years of the Space Race, success was marked by headline-making, historical "firsts." Some of these firsts included the first satellite, the first robotic spacecraft to the Moon, the first man in space, the first woman in space, and the first spacewalk. To the chagrin of the United Sta .....
