Science breakthrough ii
- 1. Science and Technology Science Breakthrough II
- 2. INTRODUCTION A scientific breakthrough is an euphoric moment that reveals an idea or even an accidental answer to a need or problem. Many scientific breakthroughs were developed into technologies that helped improve the quality of life by giving us cures for diseases, increasing food production, improving procedure for solving crimes, and developing machines that do work more efficiently. Some scientific breakthroughs were discovered accidentally and led to other breakthroughs, while others were made through the perseverance of the scientists. Gadgets are examples of these breakthroughs.

- Early Hunting and Gathering Tools An assortment of prehistoric tools provides evidence of the hunting and gathering methods of early peoples.

- Early Agricultural Tools Humans began farming about 12,000 years ago. The ability to control their food supply freed people from a nomadic lifestyle, which allowed for the beginning of cities and towns. These early farming tools date from about 6,000 bc. The picture portrays an axe (bottom) used for clearing; flint sickles (left), used for harvesting cereal crops; a flat rock and rounded stone (center), used for grinding flour; and perforated clay slabs (upper right), probably used to ventilate bread ovens.

- Wheel, circular frame or disk, constructed to revolve on a central axis, and constituting an integral feature of most ground conveyances. The earliest known wheels, constructed in ancient Mesopotamia, date from about 3500 to 3000 bc (see Technology). Wheeled vehicles are believed to have appeared after the invention of the potter's wheel, and the wheeled cart soon replaced the sledge as a means of transportation. In its simplest form, the wheel was a solid wooden disk mounted on a round axle, to which it was secured by wooden pins. Eventually sections were carved out of the disk to reduce the weight, and radial spokes were devised about 2000 bc. The invention of the wheel was a major turning point in the advance of human civilization. The wheel led to more efficient use of animal power for agriculture and other work; it became an invaluable mechanical means for controlling the flow and direction of power or force. The applications of the wheel in modern life and technology are virtually infinite.Microsoft ® Encarta ® 2009. © 1993-2008 Microsoft Corporation. All rights reserved.
- In 1928, Alexander Fleming left petri dishes containing cultured staphylococci bacteria before going on a week-long vacation. Upon returning to his laboratory, he sorted through the stack of discarded petri dished and was surprised to observe that a mold had entered and contaminated his culture. However, this mold, was inhibiting the growth of harmful Staphylococcus aureus bacteria. Something produced by the mold was dissolving the bacteria, practically wiping off the dish clean even without the aid of a disinfectant. That something was actually a powerful antibiotic, which he named penicillin. Best of all penicillin was not poisonous to humans. The medical community did not did not accept Fleming’s new discovery. Scientist during that time believed that once a bacterium entered the body, there was nothing that could be done. Penicillin was seen insignificant and of no science interest. Fleming was seen insignificant and of no scientific interest. Fleming was not a chemist and so he could not isolate the active ingredient; neither could he keep the penicillin long enough for human use.
- During the World War II, two medical researchers Howard Florey and Ernst Chain, provided medical assistance in the battlefield with the development of a powdered form of penicillin. In 1941, the first human was successfully treated. Before long penicillin was in full production. Fleming, Florey, and Chain were awarded the Noble Prize for medicine in 1895, 17 years after penicillin was discovered. This breakthrough helped cure diseases such as gonorrhea, meningitis, diphtheria, and pneumonia.

- Fertilizing the ovum outside the mother’s womb gave new hope to many couples who could not have a child under natural means. In vitro fertilization (IVF) is one of the breakthroughs that have become part of what is throughs that have become a part of what is known as assisted reproductive therapy (ART), which treats barrenness or the inability of a woman to become pregnant. The first test tube baby was born to Lesley Brown, who was told by her doctor s that she would never be able to give birth. However, other doctors obtain her egg and fertilized it outside her womb, and give the world its first test-tube baby: LOUISE JOY BROWN, born July 25, 1978. The successful birth was carried out by the gynecologist Patrick Steptoe and two other doctors Robert Edwards and Barry Bavister. In vitro fertilization involves taking an ovum (egg) from the mother’s ovary, fertilizing it in a test tube with the father’s sperm, and returning the fertilized ovum into another woman’s womb for the egg to developed. Many ethical and moral issues have cropped up regarding test-tube babies, especially when the egg is made to grow in another woman’s womb, who is not the biological mother of the baby. Another and even more serious issue is the fate of other embryos that produced but not implanted into the womb. What happen to this human embryos? On the other had, whatall such embyos are implanted and all grow into full-term babies?
