Dolly How Dolly Was Made In February of 1997, Dolly, was the first mammal to be cloned from an adult sheep. The world was astonished by this feat, because he drew attention to the theoretical possibility of cloning humans. The clones were made from "cultured cells derived from easily obtained tissue should bring numerous practical benefits in animal husbandry and medical science." "

Xenotransplantation I would like to state the facts and corolations upon the subject of Xenotransplantation - the transplant of animal organs into human beings - is a multi-billion-dollar business venture built on the anticipated sale of patented techniques and organs, as well as drugs to overcome organ rejection (1). It has received strong criticism and opposition from scientists warnin

The Perfect Wave The Perfect Wave The sky was crystal blue. There was a slight breeze blowing off of the shore tickling the treetops causing the birds to chirp quietly. The palms were rustling gently almost in unison with the crashing of the waves, like a natural symphony. Each wave crumbled slowly up the beach in foaming broken lines, only to peel back down the beach, slowly and ca

Science As Supreme Science comes from the Latin verb scire, which means “to know”. Taking into account this definition, it suggests that for some people science is the ultimate form of knowledge and certainty. Therefore, knowing one thing can lead to many more different aspects of life and knowledge as a whole with the use of inductive scientific experiments. I think this is a very reaso

Bio-ethics Role Bio-ethics Role Bio-ethics is the study of ethical implications of medical practice, considering the preservation of human life. With recent science developments, scientists have the ability to control the future of humanity. Human cloning is a controversial issue that has a neither right nor wrong answer.

Hirschsprung’s Disease Hirschsprung’s Disease is a condition caused by non development of ganglion cells in the wall of the large intestine. This occurs in a fetus before birth, this causes a lack of peristalsis in the large intestine. Consequently, fecal matter backs up causing either partial or complete intestinal obstruction. Eventually a bacteria infection can develop in the intesti

Telescopes Reflecting Telescopes use a mirror to gather light and bring the image to the eyepiece. These telescopes are often referred to as "Newtonians" because they were first conceived of by Isaac Newton. Reflectors utilize a parabolic mirror that reflects the image to a focal point. Since the mirror reflects the image back towards the source, a small secondary mirror set at an angle

Each system has its pros and cons and its unique features making it invaluable. Operational overview: X-ray machines have several components including the source, an intensifying grid and a film.

Science Laws Scaling laws are extremely simple observations about how physics works at different sizes. A well-known example is that a flea can jump dozens of times its height, while an elephant can't jump at all. Scaling laws tell us that this is a general rule: smaller things are less affected by gravity. This essay explains how scaling laws work, shows how to use them, and discusses t

Color Research Paper Color is sensed when white light bounces off an object and is reflected into the eye. Objects appear different colors depending on what colors were absorbed and which were reflected. Color is \"seen\" by the rods and cones in the eye. Cones detect color and rods detect black, white, and shades of gray. People who cannot see colors properly are colorblind. There a

Sexual Dimorphism Sexual dimorphism is secondary sexual characteristics, marked differences, which are not directly associated with reproduction. It is a distinction in appearance. The distinction in appearance can range from size or in features that show more colorful feathers, larger manes, or bigger antlers. Males tend to be the ones to attract females with these distinctions, at l
