The Fertilization Process and Implications of Test Tube Babies
Through the wonders of science, infertile couples who were previously unable to bear children, due to reasons such as blocked fallopian tubes, low sperm count, low egg quantities or advanced age of the mother, are now able to conceive through in-vitro fertilization. The results are babies known as test-tube babies which are technically conceived outside the womb.
In a natural scenario, the conception of a baby occurs when the ovum, travels from the ovaries, through the fallopian tube to be fertilized by the sperm of the father during sexual intercourse. From this point on, the fertilized egg will travel down towards the uterus and during the process division of cells will occur until it reaches its final destination at the wall of the uterus. However, in the cases of block fallopian tubes, the eggs are unable to travel from the ovaries to the uterus and conception cannot happen.
Developed in the United Kingdom by Dr. Patrick Steptoe and Dr. Robert Edwards, the process of in-vitro fertilization involves removing eggs from the ovaries of the mother and combining them with the sperm of the father in a lab environment. The fertilized egg is then placed back into the uterus of the mother after 3 to 5 days and will remain there to grow till birth. Because of the low success pregnancy rate of this procedure, a few eggs are placed in the uterus to increase the odds of success. With this process, statistics have shown that the rates of multiple births have increased where 24 percent of the in-vitro fertilization births have produced twins.
The first test-tube baby, Louise Brown, who was born on the 25th July 1978, marked hope for other infertile couples to have a baby through this procedure. However, many others were concerned about the ethical issues surround this. One major area of concern was the fact that as the egg is located outside the womb for a few days while the cells multiplied before being put back inside the uterus, the health issues affecting this baby is unknown. Indeed, research has been shown that test-tube babies have a higher chance of birth defects and low birth weight, and researchers still have not been able to determine the reason for this.
Other issue of concern is that through this procedure, some of the eggs fertilized in the lab are later discarded. Does this procedure mean that the researchers are actually killing potential people? How is the line drawn in this case?
Then there is also the issue of commercial opportunities for eggs and sperms to be bought and surrogate wombs to be rented with the purpose of creating babies. This process of embryo transfer to another mother, not necessarily the same woman who had provided the eggs, is known as placing the embryo in a gestational carrier. This procedure has been becoming increasingly common through technological advancement, which has made couples including women with uterus problems, have a chance in having their baby.
Test-tube babies have really brought changes to the way in which babies are conceived and have given much hope to many who have had problems having babies through the process of . However, the downside of this are the ethical issues behind the procedure, with which still poses a big question mark and with which is still opposed by many factions.

Dr. Richard Waller has been helping thousands of infetile couples and gave hope to childless women since 1999 through the process of in-vitro fertilization. He is based in England.

How I Became Interested In Looking At The Moon
Like a lot of kids, my folks gave me a 60mm telescope for Christmas one year. The scope was a typical department-store brand - not very good - but to a 12-year old kid it opened up the universe.
There is a Core at the Center of the Earth; Right?
There are some who would like to discuss why they believe the Earth is hollow and shaped like the inside of two symbols when put together.Most scientists are quick to discount such a notion and call it complete and utter BS.
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.
The Future Enhancements of Tele-Robotics
Today we have already available UAVs, which will soon have the capacity of operating together in swarms, controlled from another nearby aircraft. We have UAVs, which can be flown by a pilot sitting at a desk more than 1000 miles away.

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.
Chimpanzees and Humans a lot in common
Those who study chimpanzees are often amazed completely with the abilities of that species. They tend to be able to raise their level of awareness and concentration to a completely higher level than we ever believed.

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.
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.
The Best and Worst of April's Weather
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 art or science of metallurgy is vital to the social structures surrounding all esoteric beliefs. They are the most tangible items of the cosmic soup that are possibly drawn to certain Earth Energy Grid locations as we shall see.
MAV Propulsion and Testing
Perhaps we should be looking into advancing the propulsion systems of MAVs, small UAVs by using magnetic propulsion to spin the propellers. When testing a UAV by trying to fly it under the canopy of trees or around sparsely populated tree areas or in cities with streets and housing we may find we have difficult issues.
Theoretically is it Possible to Defy Gravity?
Many believe it is possible to build an anti-gravity machines and there are many small version which can do this by interfering with the gravity waves. Other say why build an anti-gravity wave machine when you can use the gravity to pull you the other way.
