THYROID; REASON FOR MISCARRIAGE IN WOMEN

                                        A few drops of blood taken from a newborn can show whether the baby has a thyroid abnormality. If blood tests reveal a problem, physicians can take corrective measures. Lacking sufficient thyroid hormones, a child may become physically and mentally retarded, a condition called cretinism. Hence, babies are usually tested just days after birth.                                                     Thyroid impairment may be the result of a diet poor in iodine, physical or mental stress, genetic defects, infections, disease [usually autoimmune disease], or side effects of medications prescribed for various        illnesses. An enlarged thyroid, or goiter, may be an indication of disease. The enlargement may be diffuse or in the form of nodules. Although genetically benign goiters should always receive medical attention, for they might indicate a more serious condition, such as cancer.     Just as the accelerator controls the speed of a car

BONE; A MARVEL OF STRENGTH

                                                  Bone has been described as an engineering masterpiece of tensile, compressive and elastic strength.           The human skeleton consists of approximately 206 bones and 68 joints. The largest bone is the femur, or thighbone; the smallest is the stapes, a bone inside your ear. As skilled gymnasts clearly demonstrate, bones, muscles, cartilage, and joints can give a healthy body an astonishing degree of flexibility and range of movement. The thumb alone would convince anyone that the architect of our body [whoever that may be to each one of us].         Bones can also take an incredible pounding. They are constructed in exactly the same way that reinforced concrete is constructed. The steel of reinforced concrete provides the tensile strength, while the cement, sand, and rock provide the compressional strength. However, the compressional strength of bone is greater than that of even the best reinforced concrete. We only wish we

HOW TO MEASURING THE EARTH WITH A STICK

                                      Have you ever heard of the Greek mathematician and astronomer Eratosthenes? His name is probably best known among astronomers. Why do they think so highly of him?           Eratosthenes was born about 276 B.C.E. and received some of his education in Athens, Greece. He spent a good part of his life, however, in Alexandria, Egypt, which at that time was under Greek rule. In about 200 B.C.E., Eratosthenes set out to determine the dimensions of the earth by using a simple stick. ‘Impossible!’ you may say. How did he do it?         In the city of Syene [now called Aswan], Eratosthenes observed that at noon on the first day of summer, the sun was directly overhead. He knew this because there was no shadow cast when the sunlight reached the bottom of deep wells. However, at noon on the same day in the city of Alexandria, which was located 5,000 stadia to the north of Syene, a shadow could be observed. That gave Eratosthenes an idea.       Era

YOUR MARVELOUS RED BLOOD CELLS

                                          THE most common cell in your bloodstream gives blood its red color and is thus called a red blood cell. Just one drop of your blood contains hundreds of millions of such cells. When viewed through a microscope, they look like doughnuts with a depressed center instead of a hole. Each cell is packed with hundreds of millions of hemoglobin molecules is, in turn, a beautiful spherical structure made of about 10,000 hydrogen, carbon, nitrogen, oxygen, and sulfur iron, which give the blood its oxygen-carrying ability. Hemoglobin facilitates the transport of carbon dioxide from the tissues to the lungs, where it is exhaled.     Another vital part of your red blood cells is their skin, called a membrane. This marvelous covering enables the cell to stretch into thin shapes so as to pass through your tiniest blood vessels and thus sustain every part of your body.     Your red blood cells are manufactured in your bone marrow. Once a new cell en

THE INVERTED RETINA

      The human eye contains a RETINA –a membrane with approximately 120 million cells called PHOTORECEPTORS, which absorb light rays and convert them into electric signals. Your brain interprets these signals as visual images. Evolutionists have contended that where the retina is placed in the eyes of vertebrates, creatures with a backbone, proves that the eye had no designer.       The retina of VERTEBRATES is inverted, placing the photoreceptors at the back of the retina. To reach them, light must pass through several layers of cells. According to evolutionary biologist Kenneth Miller, this arrangement SCATTERS the light, making our vision less detailed than it might be.        Evolutionists thus claim that the inverted retina is evidence of poor design –really, no design. One scientist even described it as a functionally stupid upside-down orientation. However, further research reveals that the photoreceptors of the inverted retina are ideally placed next to the pigment
