Recent discoveries about the role of stem cells in cancer have altered the landscape of cancer research, says Medical News Today. There is, however, a long-running philosophical rift over stem cell research at both the state and federal levels. Some groups would rather focus on adult stem cell research, avoiding the moral and ethical questions about research involving embryos. While ethical debate on human embryonic stem cells will continue, much more is occurring on the rings surrounding this bull’s-eye issue, including research in both drug development and adult stem cells.

Biologists’ understanding of new sources and uses of adult and nonembryonic stem cells is advancing rapidly. Called “niches” or “crypts,” it seems that almost anyplace one looks in the body (nose, eye, hair follicle, intestine, bone marrow, central nervous system), stem cells are being found. From such basic knowledge, it has been reported that successful animal and human therapy using patient stem cells is already occurring. As more stem cell crypts are discovered, the desire to understand how to manipulate them within the body only becomes more acute.

At the 2007 Annual Meeting of the American Association for Cancer Research, researchers presented new discoveries about stem cells in leukemia, breast and colon cancer that add to the growing evidence that perhaps cancer is, fundamentally, a stem cell problem.

Interviewed by Vision Magazine at the Stem Cells World Congress earlier this year in La Jolla, California, veterinarian and CEO of Vet-Stem, Robert Harmon, explained how his company is currently providing stem cell therapies for animals. Injected into an injury or degenerated tissue, the stem cell treatment evokes healing in unprecedented ways. As it has been since its discovery almost 400 years ago, the cell and the “vital force” that makes it the seat of biological life continues to hold attention. It is likely that there will be no end to the moral and ethical questions and investigations. Today’s new age of molecular understanding, genomics, proteomics, gene splicing and bioengineering is barely underway. It is not surprising, then, that the more we know, the more we recognize how little we understand.

The timeline of discovery has been exponential: from discovery of the DNA double helix in 1953, and the understanding of the genetic code, gene splicing and cell differentiation in the 60s, 70s and 80s, science rapidly jumped up the learning curve to the cloning of whole organisms and the discovery of embryonic stem cells less than a decade ago. The future possibilities for the application of this knowledge seem enormous.

Writing political science research papers is not childs play. In fact, political science research paper writing is one of the most formidable academic writing assignments of your entire educational career. This article provides simple research paper help for writing a political science research paper without much difficulty.

* First, choose a relevant and interesting topic for your political science research paper. It is known that a topic that interests the writer is easy to write about.

* Once the topic is chosen, conduct thorough research using all the possible sources of information. Make sure to only use relevant and most authentic sources for your research papers. After completing the research, arrange all the research material in a systematic order to be able to use it effectively in your political science research paper.

* After arranging the research material and making relevant notes, prepare an outline for your political science research paper. A standard outline for political science research papers is based on the following sections:

Parts of a research paper

A typical research paper includes a title page, introduction, main body or arguments section, counter argument (if required) and a conclusion. Some institutions may also require an abstract, appendix, acknowledgements and a references and bibliographies section to be included in the research paper.

* Adopt a careful approach while writing your political science research paper. This means that you should know which type of information, data and references to add in the research paper and which not to.

* Your research paper writing should be in a flowing manner with each sentence and section composed as a logical and natural sequence of the previous ones.

* Make sure that you do not use any kind of plagiarism while writing your political science research paper because if you do, you wont only lose marks but also your reputation as a decent student.

* Use least possible quotes from the research material and only if required. It is highly suggested to write in your own words as it shows your capabilities and knowledge of writing research papers.

* Cite all references properly and clearly in the references and bibliographies section.

The above would certainly help you write better research papers in the future. For further assistance, you can also get professional research paper help from www.academic-writing.net which is the leading provider of research paper writing services.

If you are interested in the spiritual world, and would like to study the sciences beyond physical laws of the universe, you might be interested in parapsychic science schools. The classes taught at schools for parapsychic science can include a wide variety of fascinating subjects, including clairvoyance, psychokinesis, hypnosis, extra sensory perception (ESP), telepathy, and many others.

Those who are involved with parapsychic science schools believe that there is a scientific domain that defies explanation by the known laws of physics or biology. Classes can cover a diverse range of topics, such as angels, astrology, spiritual development, ethical and legal issues in holistic care, regression therapy, sound therapy, chakra therapy, spiritual healing, divination, theology, near death experiences, astral projection, psychic healing, channeling, and vibrational healing, just to name a few. You may even be able to take a business management course in parapsychic schools to help you prepare for a career in parapsychology.

While some parapsychic science training concentrates strictly on metaphysical, paranormal and parapsychic studies, there are also traditional colleges and universities offering degrees in subjects such as psychology or anthropology with a concentration in parapsychology. You will find various certificates, diplomas and degrees offered by parapsychic science schools, such as the Parapsychology Certificate, Diploma of Parapsychology, Bachelor degree in Holistic Studies, Bachelor of Science in Parapsychological Studies, and others.

Schools for parapsychic science are in the business of preparing graduates to enter one or more of the various parapsychic occupations, such as spiritual counselor, astrologer, or holistic healer.

If you are interested in the parapsychic sciences and looking for instruction in the various fields of the paranormal, you may decide that parapsychic studies should be in your future. Submit a request for information to Parapsychic Science Schools found on our website, and you could soon be entering a new and exciting profession!

Earth Science Fair Projects

Governments around the world along with private organization and companies are converging and discussing the environmental issues that are facing our planet. These international meetings are attended and lead by some of the greatest minds in the area of ecological sustainability. These leaders have spent their professional careers researching and implementing programs and policies to protect and repair the environment. They did not, however, wake up one day with all these qualifications in their heads. They have spent years and decades studying and researching their chosen field of specialty. Like other professionals, they began their careers as students. Many of these professionals are the very students who began their studies with earth science fair projects demonstrations. This was likely the first demonstration of their ability and desire to understand the systems and life forms with which we share the planet.

Earth science fair projects are the perfect venue for students who want to pursue a career in any number of environmental fields. The earth science fair projects of students often become the focus of their career goals. For those students interested in plant life, an earth science fair project on the growth of food crops might be in order. Students who are interested in the cycles of weather, and earth science fair project would be appropriate. Others who are interested in the history and origins of the very planet upon which we live could develop an earth science fair project around this huge topic. Regardless of the specific topic, earth science fair projects offer all students the opportunity to demonstrate their beginning knowledge of these important topics.

Many of the students who present earth science fair projects have plans on continuing their education at the college and postgraduate levels. These students often take the seed of interest that is planted with their first earth science fair projects and continue the studies at these higher educational levels. There are even professional who started at the high school science fair and were offered tuition and scholarships to continue their research. All the international professionals began as students, so the possibilities exist for all students interested in these fields of study. With these opportunities, students can transform their careers while transforming our stewardship of the Earth.

Unique science project ideas you can experiment on include: making your own fossil; how fogs form; gravity and the plant growth; processed food and the amount of gas; and level of pollution by day.

It’s science fair time again in Middle School. You don’t want to show the same project as you did last year like the very common mechanical volcano or the solar system models. This year, plan on something new and fascinating, check on the following ideas.

Make your own fossil

Demonstrate how fossils form. You can make use of cardboard, plaster of paris, leaver, water, and petroleum jelly. This method is to demonstrate how fossils form in mud. Mix the water and plaster of paris, spread the mixture on a cardboard. Cover the leaf with petroleum jelly and place it on the plaster. Allow it to dry then remove the leaf when the plaster dries, you now have a model for a fossil.

Describe how fog forms

Explain the 2 kinds of fogs, the advection and radiation. Advection fog forms from warm moist air blown inward. The radiation fog is the warm, moist air that forms too close to the ground. Create your own fog using two bottles with narrow necks. Fill 1 bottle with hot water and the other one with cold water then place an after several minutes place an ice cube on the mouth of each bottles. See what happens after.

Gravity and growth of plants

This experiment tackles on how plants know which direction grow. For the experimentation, observe the position of the stems and leaves of a house plant over a period of a week while laying it on it’s side and leaning on a book. Plants contain a chemical called auxin causing it to elongate. Gravity pulls it downward, the cells elongate where there is auxin accumulated, therefore causes the stem to grow upward.

Processed food and the amount of gas

The purpose is to determine whether processed food tend to produce more gas. Obtain small pieces of different kinds of processed food and place each in a test tube. A a small amount of distilled white vinegar in each tube then shake for 30 seconds. Fit a balloon on the opening of the test tube. Leave it for eight hours then measure the width of the balloons after.

Level of pollution by day

This project aims to answer if there is a relationship of the time of day or week and the amount of air pollution. Use different microscope slides and coat it with petroleum jelly. Select different places where you can place your slides and label it. Expose all slides at the same time frame daily. Collect the slides after then view it under the microscope. Observe which slides accumulate most particles.

Be creative and enthusiastic in your approach. With the right science project and confidence, that science fair ribbon would be yours.
