...then went on to develop into little frogs," he told ABC radio's AM program. "And like any pregnant mum, when you have little babies rattling away in your stomach saying, 'let me out', she would then open her mouth and out would pop little frogs. "The first people that saw that were aghast. By the time anybody got excited about it, suddenly it was extinct. "So that's certainly one of the driving reasons why this would be a focal animal for seeing if we can de-extinct this amazing frog." That is exactly what a team of Australian scientists is doing. After locating a few carcases stored in a deep freezer, they have been able to recover tissue from the gastric brooding frog. Using a laboratory technique known as somatic cell nuclear transfer, they have implanted the dead cell nucleus from the extinct species into a fresh egg from another related frog. The reproductive process then took over, and the scientists have created an embryo. "There was one day in the laboratory that was so exciting when all of a sudden the egg from this living species that had had one of these extinct frogs nuclei inserted into it, started to divide,...

...Animal Rights Since the beginning of living, the interaction between man and animals have been something unavoidable. The encounter in the wild, the hunter and the hunted, and the survival of the strongest are the rules of the jungle an it is because of this relation that we have with the animals that people have been study them. The philosopher Pythagoras was one of the first person who talked about animal, describing their soul were in the same category as the humans begins. Also, in the Bible is told that the humans are in a superior level when they justified that a bled animal can be eaten. Rene Descartes wrote in his meditations that animals do not have soul; therefore, they are not able to feel and their treatment can not be consider as a moral issue. Knowing that there is a lot of controversy about the animal rights, is inevitable to ask what are the advantages and disadvantages about giving them rights? The first and maybe the most important factor that we need to discuss firstly is the ability that both, humans and animals, have to think and feel. On one hand, human beings are complex evolved creatures who are accorded rights on the basis that they are able to think and to feel pain; additionally, any other animals are also able to think (to some extent) and are certainly able to feel pain. Therefore non-human animals should also be accorded rights, like a free and healthy life. However, on the other hand, human beings are infinitely more complex than any other...

Lithium carbonate is used as a mood stabilizer in psychiatry to treat bipolar disorder (manic-depression) in daily doses of about 0.5 to 2 grams, although there are side-effects. Excessive ingestion of lithium causes drowsiness, slurred speech and vomiting, among other symptoms, and poisons the central nervous system, which is dangerous as the required dosage of lithium to treat bipolar disorder is only slightly lower than the toxic dosage. The metal lithium is not essential for any biological functions, but was found to exist in extremely tiny...

...focuses mainly on internet websites and articles posted on to the internet. The articles focus mainly on the history of cloning and the various ways that nature has used cloning and how mankind has extended natures approach and ultimately advanced cloning methods and the new technology that has been discovered because of these advances. The articles contain proof that further advancements in cloning can develop possibilities in preventing and curing diseases. There is discussion on how continued research into therapeutic cloning can expand the knowledge of how certain diseases and cancer attack the body, and how this knowledge can help fight and even eliminate both these issues. Another topic of discussion is how cloning could lead specific cell production of various organs and tissues through-out the body which can lead to curing failing organs and even the possibility of growing replacements organs thus doing away with then need for lengthy organ transplant lists and the needless suffering of thousands of patients a year. The paper contains the various ethical and controversial arguments that human cloning bring up.

...uses the water to break down the sugar molecules in to simpler and smaller compounds such as simple sugars. It acts on different substrates to break it down as it is a catabolic enzyme. The important substrates are lactose, lactoslyceramides, gangliosides and many other glycoproteins but lactose is an important substrate and sometimes this enzyme has been recognized by its sub class that is lactase. Beta galactosidase is actually a chemical name employed to a large group of the enzymes. Enzymes are the proteins that takes part in the catabolic activity within the cells and they act as a catalyst that is enhances and makes it faster the reaction of the hydrolysis of the molecules that would otherwise be slow and the normal physiological process can be slowed down and the life of the cells would not be possible anymore. The enzyme known as β - galactosidase is not only present in eukaryotic cells but also in prokaryotic cells. As the word indicates galatosidase, it means the breakdown of the large chain sugar lactose into smaller molecules such as glucose and galactose (Casadaban et al., 1983). Lactose is polysaccharide that is the large sugar which is formed by the combination of two smaller molecules such as glucose and galactose. In order to determine the quantity of the breakdown of lactose, one method can be adopted which is Bradford assay. In this method the Coosmassie Brilliant BlueG-250 makes bonding with a protein. This binding results in the shift in the absorption and maximum...

...TREE GOD MOTTO: My motto is to help people, plants, animals and birds to live a happy and healthy life without polluting the environment but save more for the future and make it brighter. NOTE: Without tree there is no life. A mother gives us life by giving us birth and a tree is even greater than a mother as it gives us birth every day, every second to numerous living beings in this earth. IDEA: The idea about my plan is regarding a social service that is helpful to the environment in reducing pollution in the atmosphere by planting saplings and making sure that they grow into big and health trees. It is important for me to mention that this is totally a non-profitable organization and the main motto is to give life to birds and animals as trees are considered to be a shelter to living beings. This organization is named as, ‘Tree God’. This name is inspired because a tree gives us life every second and everyday just as God does. Without trees, there is no life on Mother Earth. Plant trees to save the life of all living beings and mother earth. Save your lungs. Do not pollute the environment. If you do, this is what you will go through... Without a tree it is not possible for a human being to even survive for even a second as trees breathe in carbon dioxide that we release and breathe out oxygen that we inhale. This oxygen is very essential to human beings or any animal. The beauty about a tree is that, it absorbs poison that we release...

...paperEarly in 1997, Scottish scientist Dr. Ian Wilmot revealed to the world that he had successfully cloned an adult sheep, Dolly. With this invention, the world made a collective gasp at the realization that cloning was no longer a pipe dream or an element of a Science Fiction movie. Since then, human cloning has become one of the most debated topics in the world. From the schoolhouse to the White House, discussions began regarding the ethical implications of human cloning. In several recent polls by TIME magazine (The Ethics of Cloning, 1998 ), it was shown that 75 percent of the responding population thought that cloning wasn’t a good thing. Furthermore, 74 percent of the respondents believed that cloning was against God’s will, and when asked if they would clone themselves, if presented with the opportunity, 91 percent responded with a “no”. However, when asked to define human cloning, an estimated 95 percent of them couldn’t describe it correctly. As a matter of fact, in a personal interview with Miss. Weber, T.A. (personal interview, November 7,1998) when asked, “What do you think about human cloning?” responded, “I don’t know a lot about it, but I know it’s scary”. Opponents of human cloning argue that it is immoral and unethical to clone human beings for both religious and humanitarian reasons. Moreover, other opponents describe human cloning as a luxury for wealthy people or as a tool for organ market development. Conversely, I believe that human cloning can have many...

...Mario Gonzalez Professor Stamp English 1B 16 March 2014 Wall-e We as humans have the ability to live our own lives without the use of constant technology. Even so we have become dependent on it to live our daily lives. Less than a century ago we lived without being so dependent upon technology and we can again. Not to say that we should abandon technology completely but we have become entirely too dependent. In the Pixar movie “Wall-e”, humans have destroyed the planet due to their lack of care for the environment. They then are regrettably forced into living in space on a ship called the Axiom because the planet is inhabitable. Wall-e is just one of many robots who have been created to help clean up the planet. The people on this ship have everything given to them and have no intentions of returning to Earth anytime soon. Although the movie does take the extreme route, it is a good depiction of how we are becoming more and more reliant on technology which could prove to be detrimental . In Wall-e every aspect of humans lives on the Axiom are consumed by technology. It tells them what to do and when to do it. They are waited on by the robots so that they don’t even have to walk or get up from their chairs at all. Their screens block themselves from the outside world and what is going on around them. They are sucked into their technology so much so that they have almost lost any contact with other humans at all. Even the simplest of tasks are done for them such as brush...

...Biotechnology Biotechnology is the way in which man uses other organisms to make useful products. Yeast has been used for centuries to make beer, wine and bread. Moulds have been employed in cheese making, and bacteria in yogurt making. Single- Cell Protein (SCP) Microorganisms are single cell organisms which can be cultured to rapidly produce foodstuffs rich in protein, minerals and vitamins. Microorganisms are grown in large fermenters where nutrient, pH and temperature are constantly monitored and controlled. The products are: 1. Cells 2. Substances produced by cells. 3. Substances the cells make by fermenting the nutrient solution. Once these products have been ‘ harvested’ they are processed for marketing. Mycoprotein (SCP) Fusarium graminearum is a mould which is about 50% protein, high in fibre but low in fat and cholesterol-free, called mycoprotein (myco-:fungus), it is seen as a healthy substitute for meat. Fusarium is cultured in fermenters and marketed under t brand name ‘Quorn’. Enzymes Enzymes are highly important in industry and medicine. Microorganisms are cultured in fermenters, and they secrete enzymes which are separated from the culture medium and processed to be used in powdered or liquid form. Enzyme production is a rapidly growing industry. They are used in the following areas:- Food and agriculture Chemical industry Pharmaceutical industry Medicine Analytical Sciences Enzyme Production Microorganisms are used to produce enzymes...

...The Only Home We Have “Home is the place where they have to let you in.” From the beginning of the life on earth, every living creature has felt the sense of belonging. Belonging to some place that makes us safe, comfortable and peaceful. It’s called home, in today’s language. Home is the place where we all born, raised and come back again everytime when we leave. It’s what we need to be able to continue living. Since the life has begun on the earth, nature is the home for all living creatures. As Robert Frost said, nature lets every living creature in when they born, but unfortunately humankind is not able understand how precious the nature is and how should we treat the nature. Earth is our nature, the only nature we can live and survive as far as scientists discover another nature in the outer space. But the question is, are we showing the same respect nature shows us by letting us in without wanting anything in return? The answer is obvious and worrying. We, as humans, are disrespectful, self-centered and reckless towards the nature because of the materialistic perspective we have and the nature is keeping used and consumed by us as the ‘perfect tool’ to achieve our materialistic determinations, pleasures and comfort without realizing it’s the only home we have. Instead of showing gratitude to the nature, humans use the nature for materialistic determinations and benefits. Considering how was the nature when the life first started on earth and how it is now, a great influence...
