Embryonic Stem Cell
Stem cells are primitive undifferentiated cells that have the capability to form any of the 220 different types of cells in the human body. The embryonic stem cell is found in the embryo and develops into various cells that make a baby. This single cell is capable of forming or specializing to form any kind of cell. During embryonic development the first cell quickly divides to form three embryonic layers namely, the ectoderm, the mesoderm, and the endoderm. Embryonic stem cell research and the method of cloning led to the development of the famous cloned sheep, Dolly. Cloning essentially involves the duplication of biological material. This is done through a technique called somatic cell nuclear transfer. This method can create a clone as well as be used for producing an embryo from which cells called embryonic stem (ES) cells could be extracted. The advantage of embryonic stem cells is that they can be used to cure several fatal genetic diseases. Embryonic stem cells possess two major characteristics that make them especially suited for cell therapy. Firstly, being extracted from a very new organism, these cells are at an early stage of development and can be more flexibly used to culture several different kinds of cells. Stem cells that have such a flexibility of development are referred to as pluripotent cells. Also, embryonic stem cells have the ability to remain undifferentiated for long and can divide indefinitely. This makes them self-renewable and they can be used for longer. If transplanted into a patient's body, embryonic stem cells are capable of replenishing cells that have been destroyed by ailments like sickle cell anemia, thalesemia, and some forms of cancer.

The Wages of Science In the United States, Congress approved, last month, increases in the 2003 budgets of both the National Institutes of Health and National Science Foundation. America is not alone in - vainly - trying to compensate for imploding capital markets and risk-averse financiers. What is Science? Students often ask; "What exactly is science?" Professors explain by discussing theories, proofs, laws of physics, observations, duplication of results, etc.. 747 Onboard Laser Might Cause Mistake and Identity Remember when the Russians shot down a Korean Airlines 747 accidentally, which was 4 degrees off it's course and flew over Russian Airspace. Migs shot it down with two missiles, one hitting the tail and one hitting the left wing, everyone on board died. DNA Testing Breaks Down Barriers in the Court Room DNA testing has three major applications for forensic studies: identification of missing persons; identification of victims of wars, accidents, and natural disasters; and crime investigation. Annually, more than 20,000 forensic DNA tests are performed in the UK. Preventing Flooding on Individual Farmers Fields to Save Crops I propose permits be given to farmers to they can set up along the edge of their fields a microwave array to burn a hole in the clouds when severe weather threatens their crops. I would propose that this concept be completely privately funded and be done in conjunction with the FAA. Conspiring to Create Our Weather Some say the weather is totally random and does not exist in any pattern. Even some academia wonder kids show us kaleidoscope pictures of randomness and say see; this is why we cannot predict the weather. Cord Blood and Its Uses Cord blood is the blood left in the umbilical cord and placenta after the birth of the child and is collected after the cord has been cut off. The umbilical cord is routinely discarded with the placenta after a child is born. Building a Single Unit CO2 Laser Grid When using a CO2 Laser to shoot down an incoming projectile, which enters a safety zone, it will be necessary to hold the laser on the target for about 5 seconds or more. To do this we must be able to shoot the laser in a grid, therefore if the projectile or aircraft or guided missile or even a UAV takes evasive action such as a high- speed high "G" 90 degree turn you can still register a kill on the target. Trojan World War TROJAN WORLD WAR: - Homer said there were nineteen battles and we know there was a 400 year dark age that followed this enigmatic period which has almost been immortalized in fairy tales about wooden horses and fair maidens. We have given evidences of white men in the Americas at places like Poverty Point and the mouth of the Amazon (there is much more in the 'mysteries' section) as well as allover the world. Medical Miracle or Mistake? Fundamental elements of life and the aspects of cloning bring dramatic advancement to the scientific and medical community; however, is this fast-paced artificial reproduction an intrusion of Nature or a doorway to infinite, medical cures?In lieu of scientific developments in the biological mainstream, the human intervention of life and it's natural state are of utmost concern. Questions are being raised as to what constitutes life produced naturally into this world as opposed to man-made biocreationism. Remote Control Bacteria; We Can Not Allow That. Remote Control Bacteria. Why not, we have remote control everything. Composite Materials in Ships, Pipelines, Liners and Aircraft One future problem, which has not sufficiently been addressed, is that of the fumes and smoke created when composite material burns. Composite material is a truly great human achievement in material science, however as we use this material in more and more places we need to be acutely aware of the risks and potential consequences of their use. UAV Defense, UAV Recovery, Material Research, Infected Birds with Virus Plastic Net When Manufacturing nets of any type: Going for strength and light weight is a challenge and it has been the compromise of many for so long in the battle to find the strongest net, sheet of plastic to mimic that of a Spider's web we have endured to no end. It is always and shall be for some time one of man's most important conquests in many of his fields of endeavors such as fishing. Drought Worsened in Some States in 2004; 2005 will be very telling The drought of the West appears to be the worst in over 500 years. This is what the scientists at the U. Tunneling Concepts for Advanced Warfare I propose research be done to make unmanned tunneling machines to help in warfare. Today more than ever we see the problems with urban warfare. Aluminum Oxide to Disrupt Laser Weapons In a defensive move to eliminate communication of an enemy, an offensive system using a chemical laser would be a good idea. In manufacturing we have lasers, which coat materials so they can be combined or heat-treated in the application process. Earthquake and Disaster Delays in Scientific Innovation In our present period we are continually reminded that we live on the surface of the planet and with that great honor comes issues of Mother Nature we must deal with. It is a fair trade off, as you get sunshine, warmth and heat from the sun; water, fish and surfing opportunities from the ocean and the stars, moon and cosmos to propel thought, enlightenment and understanding of who we are and perhaps some insight into why we are here. Surgical Biomaterials and Tissue Regeneration Technologies Plants, invertebrate animals, amphibians and even reptiles have the ability to regenerate lost or damaged body parts. In the case of lizards, for example, this is a defensive mechanism. Using Mosquito MEMS to Collect DNA Samples Soon scientists will have scaled down robotic insects. This is a good thing and most of this technology is being funded for Department of Defense uses as they will have a killer application there indeed. Hurricane and Typhoons Show Drop in Ozone Levels A recent study, which was conducted by the Florida State University, showed that ozone levels drop as the Hurricanes get bigger. The NASA funded study looked at readings in the upper atmosphere of 12 storms.
