The "fuel cell cars" currently being advertised are being touted as "having no emissions except water." In a limited sense that is‚ in fact‚ true. However‚ if the entire fuel cycle for the car is considered it most certainly is not. The fuel used by the fuel cell is hydrogen‚ very pure hydrogen. Combined with oxygen from the ambient air‚ the fuel cell produces electricity that powers an electric motor and other devices in the vehicle--just like the battery-driven electric vehicles already on the

The use of cell phones in drivers have been linked too frequently in accidents. There are too many distractions in life as it is‚ are we so arrogant to think that we are such amazing drivers that we can do several things at once? Most accidents involving cell phones wouldn ’t have happened if the driver wasn ’t distracted. When we drive that should be the only activity we are doing.

distasteful blessing to most‚ stem cells taken from aborted fetuses in order to conduct forward-moving health research‚ causes ethical chaos between those of 21st century science and those of impenetrable morality. The pros of this research factually out-weigh the cons created by humanity’s biased principals‚ but these ethical principals endowed to society upon generations will always argue what is “truly right.” What research has been done in the use of stem cells has shown to be very successful

Introduction Leukemia has led to a significant change in the world of Science and Technology. It became the basis of research for discovering several possible cures to counter this killer disease. This is the beginning of a new medicinal era. Leukemia is a kind of cancer of the blood or bone marrow which is caused by an immature increase of white blood cells. These are called blasts. For several years‚ there are approximately 256‚ 000 children and adults around the world who have developed

Embryo research is coming up in headlines more and more every day. It’s a common controversial subject. Embryo research is the proposal to use human embryos to grow stem cells or master cells that form immediately after a human egg is fertilized. The master cells or stem cells develop into all parts of the body‚ brain‚ blood‚ skin‚ and muscle. Many people argue if the embryo research is right or wrong and if it’s beneficial or just a waste of time. There are some good things about embryo research‚ but

between embryonic stem cells and adult stem cells is that the embryonic stem cells are pluripotent stem cells that are from the inner cell mass of the blastocyst. Adult stem cells are undifferentiated cells and are found throughout the body. The adult stem cells are multiplied by cell division to replenish dying cells and revitalize damaged tissues. Totipotent cells are stem cells that are capable of giving rise to any type of cell or a full embryo. A pluripotent cell is a stem cell that can give rise

However there are moral‚ ethical and religious matters which lead to people being against the use of ES cells. The state of “homeostasis” is
