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.

Will Clones Run the World?
In the US it appears that we have decided that "life is not for sale" and that the cloning debate is over and our scientists are forbidden by law from attempting to clone humans. In other countries they are currently trying and will most likely continue to try until they get it right.
Hydro-Mini Tsunami-Perpetual Wave Making Machine
Let's describe this idea as a Self Generating a Tsunami-Perpetual Wave Pattern Making Machine to Derive Mini-Hydro Power Systems in Rivers.Hydro-Mini Tsunami-Perpetual Wave Making Machine.
Secrets of The Mathematical Symmetry of Nature and Patterns of Erosion
As scientists and theorists study patterns, design, chaos, complexity they often turn to nature for examples and there is plenty of examples in nature too. The stripes on a zebra, patterns on a butterfly, spider webs, leafs on a tree, scales on a fish, seashells, brain waves, muscle structure, texture of granite, spider webs, Earth cycles, waves on the ocean, wind flow, clouds in the sky, Rainbows, Solar System, structure of a meteorite and even DNA itself.
If we are having difficulty getting recruits into the army; lets hire some robots? General Patton's famous quote goes "?an army moves on it's stomach" and if you look at the needs of humans to complete a mission they require much in the way of logistical support, where as robots do not, sure some, but much less and we are not just talking about chaplains, psyche councilors, medics, recruiters, human resource personnel and cooks. Any component under the Joint Chiefs is full of a complexity of needs.
Army Mobile Command Center for UAV Launch
After visiting the Denver RC Modeler Club one day as they practiced for the national finals in PHX that year, we attempted a touch and go landing on our Blitz Mobile, which is a 74 foot long NASCAR type truck and trailer. Probably nothing more than a Fighter Pilots son from the cold war wanting to re-invent the aircraft carrier concept on a almost nano scale? We were successful on doing a touch and bounce on the top of the trailer without too much difficulty.
Static Charge Pulse on Wind Generator Material Memory Blades
Wind Power is considered a clean industry and is amongst the favorites of environmentalists and clean energy supporters. Unfortunately the wind generators rely on the wind and the wind is somewhat inconsistent in that sometimes it blows and some times it does not.
Fire Escape System Concept
What if in the event of a fire the building system started putting out instructions using sound waves of the best possible escape route? Using the pictures on the wall and windows to guide trapped occupants and guide them to the safest exit? It is all possible now due to an old technology which is now being used thru a transfer into the public domain. Smoke inhalation is the number one cause of death in fires.
Science Fiction by Arthur C Clarke
It is difficult to have a discussion with someone about science fiction if they are not familiar with the works of Arthur C Clarke. The concepts are not too awfully difficult to understand and not nearly as complex as reading Issac Asimov for the science fiction novice and anyone can enjoy Mr.
Droughts and Salt Water Canals Random Thoughts
We need solutions to our drought crisis in this country. There are simple but expensive solutions; for instance; Desalination, salt water rivers and conservation strategies.
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.
UAV Air-Breathing SAM Upgrade Recommendations
Can a hybrid Surface to Air Missile, UAV loiter for hours and then become a missile to down an enemy aircraft?Small UAV surface to air missile (SAM), which is air-breathing is a good idea and yields many possibilities to the future of air combat.http://www.
Aerodynamics and Hydrodynamics of the Human Body, Birds, and Boeing
The aerodynamics of the human body are very interesting indeed. This may sound somewhat funny, because human beings can't fly, however our desire to fly has enabled us to adapt and innovate to achieve the same purpose.
Veterinary Hematology 101; 2005 Abstract
Veterinary Hematology is more than just blood cells. Blood, highly functional and truly definitive, does much more than provide for the transport of cellular metabolites and waste products.
MP Apprehension of High Strung or Drunken Soldiers
Recently scientists have discovered the hydrogen sulfide gas caused mice to go into spontaneous hibernation. The genetic similarities to the mammalian class humans belong to includes these rodents as well.
Stem Cells (The Truth)
The much publicized stem cell research debate focusing on moral arguments is off target with the goal of real progress in the direction of human physiological benefits potential. No matter what side of this issue you come down on, practical considerations ultimately trump this emotionally clouded subject.
Submarine Propulsion and Internet web sources
Let us discuss the patent for the Submarine, which is now in the public domain, not that any foreign governments ever cared since they have been building them for years. Since my Grandfather built the first Ring Gyro at Stanford Research years back, I think it wise to discuss these things in a modern context.
Lets Get Dirty
There is no right way of saying this, so I'll say it the wrong way: in order to stay healthy we must stay dirty. Now, that didn't sound right, did it? Put it this way: if we all lived in sealed apartments where only the purest air was pumped in and every trace of bacteria were eliminated from our food we probably wouldn't last long when we stepped outside.
June 2005: Weather Forecasts for Vacationers
If Johannes Kepler, the renowned 17th century astronomer and discoverer of the planetary laws of motion, could speak from the heavenlies, he might have a few words of wisdom to share with the National Weather Service. Although Kepler's name is not normally associated with meteorology, he was quite the weather forecaster in his day.
The Bill Clinton Neuron And The Sweat Neuron
In the world of science, there is excited speculation about recent discoveries of individual neurons in the brain, with striking capabilities. They had discovered a neuron, which fired on recognition of just one special face.
Megaliths and Pole Flips
The changes in the earth magnetic field away from the 7.8 cycle rhythm that it has been for a long time is something that may be a result of the things man has done to the Earth.
