The article "The Ethics of Egg Manipulation" published in Nature investigates the research challenges in reducing diseases that can be identified prior to egg fertilization. Scientists have questioned if it is necessary for humans to give birth to offspring that are at high risk for genetic diseases. Their hypothesis is: If we remove the bad parts of the DNA from one egg and replace it with good DNA from another egg and use the new egg for in vitro fertilization, can we reduce the number of babies born with disease (Anonymous, 2009)?
Current experiments have been performed on monkeys. The experiments have been successful and scientists believe the research is ready to move to humans, but many laws are in place to deter this type of experimentation. Two main issues prevent further experiments: (a) the destruction of eggs with bad DNA is against the moral values of many groups and (b) financially supporting embryonic experiments with federal funds is illegal (Anonymous, 2009).
Eventually the eggs will be fertilized in order to see if the transfer of DNA can successfully create a new human embryo after fertilization. The fertilized egg will need to be implanted in a woman who is willing to participate in the research. Currently, federal funding for projects that use human embryos is banned. Making things even more difficult is the fact that with the exception of New York State, women cannot be paid to donate their eggs to research. Without human eggs to experiment on, without the ability to bring the eggs to term and see a child born and watch the child grow up, followed by the monitoring of his or her health over many years, the experimentation cannot be completed (Anonymous, 2009).

Students in the 21st century have the opportunity to learn at a rapid pace, through the use of new media and new pedagogical methods. New media shifts the pedagogical focus away from fragmented knowledge towards a more integrative and multidisciplinary understanding of the natural world. 21st century learning engages students with material, encouraging them to think creatively and critically rather than simply learning by rote memorization. Science curricula in public
Life After Death Is there such a thing as life after death? This is a question which has attracted the attention of philosophers, scientists, and religions for centuries. The difficulty with the question of life after death is that there exists no genuine persuasive proof on the question one way or another: attempts to prove the phenomenon are seldom universally persuasive. In examining some realms in which the question of life
The entire look and feel of Kunming was different because of the way factories were developed and houses were built. People had fewer options and opportunities. In spite of the hardships that communism posed for Chan and her family, she remained strong. She never lost hope that one day she would start a new business. It was years before her dream came true, and it was not easy. The move
SCIENCE FICTION & FEMINISM Sci-Fi & Feminism Origins & Evolution of Science Fiction As with most things including literature, science fiction has progressed and changed a lot over the years. Many works of science fiction were simply rough copies and following the altready-established patterns of prior authors. However, there has always been authors and creators that push the envelope and forge new questions and storylines that have not been realized or conceptualized before.
76). As automation increasingly assumes the more mundane and routine aspects of work of all types, Drucker was visionary in his assessment of how decisions would be made in the years to come. "In the future," said Drucker, "it was possible that all employment would be managerial in nature, and we would then have progressed from a society of labor to a society of management" (Witzel, p. 76). The
Essentially, it is a systems theory that sees systems that are apparently disorganized (that is unpredictable because of the large amount of variables) as systems that do have order, it is just complex and we need to find it. Some call it the butterfly effect due to that the flapping of a butterfly's wings in China might have an effect on Peru's weather. Even the most sophisticated computers cannot
