Blood Groups and Transfusions Why Blood Types Matter When Europeans first experimented with blood transfusions in the 17th century, so many patients died that the procedure was outlawed in England, France and Italy. It is said that the Incas in South America began transfusing blood much earlier, and that fewer deaths resulted. If so, the reason, not understood at the time, may have b

History Of Cell Membrane In the early stages of the twentieth century, little was known about cell membranes. Until the early 1950s, the biological cell membrane was rarely mentioned in scientific literature. It was recognised that something was probably there, but hardly anything about it was known. Considering the lack of technical equipment available a century ago, scientists such as

History Of Computers In The United States Only once in a lifetime will a new invention come about to touch every aspect of our lives. Such a device that changes the way we work, live, and play is a special one. A machine that has done all this and more now exists in nearly every business in the U.S. and one out of every two households (Hall, 156). This incredible invention is the compute

How A Basketball Player Vertical Jump Hang Time A basketball player starts in a bending position, The reason for this is that since he is starting at 0 velocity he needs all the momentum he can get to jump at least a foot higher than he can touch. Bending his knees between a sitting and standing position allows him to accelerate and explode up as high as possible, which fight gravitatio

Hot Zone The Hot Zone Just like a Hollywood movie, Richard Preston’s book The Hot Zone tells a story of an almost viral outbreak in suburban Washington, D.C.. Unfortunately, unlike a movie made for entertainment, The Hot Zone recalls the events that led to Americas encounter with the Ebola virus. Richard Preston takes you back to the origins of the virus to give you some history, a

Hubble Telescope Introduction Since ages Space have been a mysterious and interesting subject that we human beings only could stare at, until the development of the telescope all astronomical observations were made with the eye. By using measuring instruments, astronomers documented the positions of the planets against the background of stars. In 1609 Galileo Galilei turned his telescop

Bipolar Disorder Bipolar affective disorder has been a mystery since the 16th century. History has shown that this disorder can appear in almost anyone. Even the great painter Vincent Van Gogh is believed to have had bipolar disorder. It is clear that in our society many people live with bipolar disorder; however, despite the amount of people suffering from it, we are still waiting for e

DNA Mysteries And Miracles DNA: Mysteries and Miracles In the year of 2000, President Bill Clinton stood before the nation and made an announcement that was 47 years in the making; the preliminary draft of the Human Genome Project was complete.

Geology Essay Exam Of the many ideas of how the Solar System was created, the most commonly accepted is the Nebular premise. This hypothesis states that the Solar System was at one point a gaseous cloud that would develop solid particles over time. These particles would eventually progress into planets (with the exception of Pluto) and more related to our discussion, form what is now

How To Grow Marijuana MARIJUANA Marijuana is a deciduous plant which grows from seeds. The fibrous section of the plant was (has been replaced by synthetics) used to make rope.

Human Reproduction Reproduction is the only way nature has of preventing human life from becoming extinct. The male reproductive system includes the testes, the vas deferens, certain glands (prostate, seminal vesicles and Cowper's glands), and the penis. The testes are two oval shaped bodies included in a sac, the scrotum, outside the body. Inside each of the testes are many tightly

Human System Many of the earth’s systems are similar to human systems they have similar functions. I picked the two that I knew really could be seen by anyone that they are similar in the earth and in the human body. The two pairs I am going to compare are the water cycle to the circulatory system and skin to the layers of the earth. The water cycle is made up of Hydrogen, Oxygen,
