late 1940s‚ began with the discovery of the isotopic carbon-14 atom. Following this discovery‚ scientists began to ponder ways to utilize carbon-14 to date previously living organisms. Since scientists knew that living organisms absorb carbon-14 at a constant rate while alive‚ they started to formulate a process to measure C-14 to C-12 ratios in dead organisms. This procedure made it possible for scientists to age an organism using this carbon ratio. To ensure the formula was correct‚ they began to

took over 1000 years to build (Scientists). I think the reason that Stonehenge was built was for religious burial reasons. During the Stone Age‚ Stonehenge appeared to become a fashionable place to be buried (Scientists). Burial mounds were found central to the landscape. The area may have been split into a Land of the Living‚ where ceremonial parties were held by relatives‚ and the Domain of the Dead‚ with Stonehenge at its Centre‚ where people were buried (Scientists).

Almost every medical advancement has involved using of animals including discovery of penicillin‚ organ transplantation‚ vaccines etc. Scientists should use animals in disease research because nowadays it is the only right way to develop drugs‚ treatments and cures for diseases and to be sure that new products are safe to use. The first reason why animals should be used in lab testing

refuses to believe any part of the global warming theory. Behind both opinions‚ there is often confusion‚ misunderstanding‚ and a general lack of knowledge. The theory that global warming has anthropogenic causes has existed for over a century‚ and scientists have collected evidence on global warming for over fifty years. In spite of the evidence‚ the public generally lives in the dark‚ constantly wondering if global warming is fact or fiction. Global warming is the increase in the Earth’s temperature

Laboratory Research Paper I. The Scientific Method Scientists see the world from a different perspective. Scientists observe the environment and the surroundings and ask questions. Once questions are formulated the next step for a scientist is to try and come up with answers. This method of inquiry and analysis is called the scientific method. As previously mentioned the scientific method starts by asking questions and then trying to find answers. "Scientists use the scientific method to construct an accurate

Research Technology has advanced a great deal within the past few years. We have learned so much information about animal’s genes and what can be done with them. However‚ with this new information brings new questions and arguments. So far‚ scientists have successfully cloned a sheep‚ a monkey‚ a bull‚ and are working on an endangered breed of ox‚ of course cloning animals and conducting research on those animals does not concern many people. When people begin discussing cloning and stem cell

His formation then started when he read the scientific works of Aristotle. Thereafter he shifted from being a natural scientist to a "historian" of science. Kuhn always referred to Aristotle in explaining his approach to the history and philosophy of science. He asks the simple question‚ "How could Aristotle‚ one of the world ’s greatest philosophers‚ be so wrong about so

that a genome contains the building blocks of life and without it‚ life would not exist as it is at this very moment? These are the types of questions that spark the interest in the human genome and genetic research. From the beginning of time‚ scientists have always shown great interest in the whereabouts of the human species‚ being that the human species are the most complex organisms living to this present day. Who wouldn’t want to know more about oneself‚ especially if it could be beneficial

case of Jesse Gelsinger. However‚ researchers have begun to use vectors that don’t cause an immune response; such as adeno associated viruses‚ virosomes and liposomes. Scientists have also harvested cells and performed gene therapy outside the body (ex vivo). This method of gene therapy does not cause an immune response and scientists can check whether or not the functional gene has been implanted into the genome. In future‚ it is likely that ex vivo gene therapy will become more common‚ as it is safer

Cory Cress Scientist of a Lifetime Werner Heisenberg was the scientist of a lifetime for many different reasons. Werner contributed to the theory of quantum physics‚ while also discovering allotropic forms of hydrogen and receiving the Nobel Prize for physics in 1932. Werner Heisenberg was a scientist of a lifetime because he thrived to learn as much about quantum physics‚ and other types of physics as possible he attended and worked at five different colleges‚ he also educated other people by
