Toxic Shock Syndrome Low Blood Pressure
1,590 wordsTOXIC SHOCK SYNDROME (TSS) was discovered almost 20 years ago. At first no one knew what was causing it, although it was quickly linked with "superabsorbent" tampons (which are no longer on the market). Eventually researchers discovered that a poison produced by a type of bacteria known as Staphylococcus aureus is responsible for TSS. Some theorized that tampons may produce small ulcerations, which allow bacteria to enter the body. Another theory is that stagnating blood within or behind the tam...

1,071 wordsAlmost 60 years ago the first antibiotics were developed, and they were created at a time when previously untreatable infections such as tuberculosis, gonorrhea, and syphilis could be almost miraculously cured. Infections like these could be a death sentence, and until recently they many be just that again. Microbes are learning the ability to fight of these antibiotics and become resistant to them. They are gaining resistance through a number of different ways, and science is in a race to keep ...

Benefits Of Genetic Genetic Engineering
1,109 wordsThe engineering of deoxyribonucleic acid (DNA) is entirely new, yet genetics, as a field of science, has fascinated mankind for over 2, 000 years. Man has always tried to bend nature around his will through selective breeding and other forms of practical genetics. Today, scientists have a greater understanding of genetics and its role in living organisms. Unfortunately, some people are trying to stop further studies in genetics, but the research being conducted today will serve to better mankind...

Somatic Cell Therapy Germ Line Therapy
1,485 wordsScience is a creature that continues to evolve at a much higher rate than the beings that gave it birth. The transformation time from tree-shrew, to ape, to human far exceeds the time from analytical engine, to calculator, to computer. But science, in the past, has always remained distant. It has allowed for advances in production, transportation, and even entertainment, but never in history will science be able to so deeply affect our lives as genetic engineering will undoubtedly do. With the b...

Dengue Fever Sore Throat Viruses
593 wordsViruses are infectious agents found in almost all life forms. The viruses are made up either of DNA or RNA, surrounded by a capsid, a protein coat. Viruses are between 20 and 100 times smaller than bacteria, or about 450 nanometers (. 000014), being the largest, to 30 nanometers (0. 000001 in. ) being the smallest which make them virtually impossible to be seen by light microscopes. Viruses often damage or even kill the cells they infect. They reproduce by releasing their nucleocapsid, or a copy...

Hydrothermal Vents Hydrogen Sulfide
580 wordsHydrothermal Vents are considered by scientists to be very unique and complex communities of organisms. The reason for this is due to the fact that unlike most other organisms, Hydrothermal Vents are not powered by the sun s energy. Most organisms on the Earth+s surface depend on plants to produce nutrients from sunlight. This process is called photosynthesis. These communities are unique in that they depend on a different food-making process other than photosynthesis. Bacteria at the vents make...
