TERRESTRIAL CHICKEN POX





 Many mysteries abound in Africa; many of them are unexplainable even with science advancement and technological greatness.
Mysteries like ghost attack, reincarnation, witchcraft, nightmares, e.t.c. have been explained in many ways but the truth is that not one of the explanations is right.

One of the amazing mystery is an unbelievable landscape in Namib Desert, what made it more amazing is the fact that is it physical that is you can see it, touch it, and feel it.

  In an area of about 2,000-kilometer swath along the western edge of the Namib Desert in southwestern Africa, patches of barren, sandy soil three meters in diameter dot the landscape.

 Each patch is girded with a ring of tall grass. To some visitors the rings look like terrestrial chicken pox or splash marks made by giant raindrops.

Local tradition has it that these circles possess magical powers. Some tribes believe that each circle surrounds the grave of a bushman who died in one of the many conflicts between Bushmen and colonialists over the centuries.
                                                                        
The local assertion is more generally accepted within the local areas and not accepted in science circle.

Scientists too have long sought to explain the rings. In 1978, assuming that over time the circles would shift position; researchers marked the centers of some with metal stakes. Twenty-two years later, the circles had not moved.

There have been abundant theories on the origin of the circles, including termite activity, poisoning from toxic indigenous plants, contamination from radioactive minerals and even ostrich dust baths. These theories were tested one after the other and they were all disproved one after the other in an overwhelming way.

    Perhaps significantly, the researchers did find that grass withered when planted in soil taken from the grassy rings, confirming that there is a difference between the soils in the two areas.

 Although initial soil testing failed to provide any explanation, Van Rooyen hopes that analysis using a mass spectrometer will turn up further information.

She wonders if there are toxic elements in the soil of the circles. But even if we find them, how they came to be there is the next problem. For now, then, the circles remain one of the earth’s many fascinating mysteries.

 Science and technology have limits and constrains especially on spiritual or mystical issues and events. It is wise to combine science and religion in every issue to get the best out of the situation

THYROID DISEASE



                               

         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’s engine, thyroid hormone regulates the rate of the body’s metabolism- chemical activity in cells that produces energy and new tissue. Thus, thyroid hormones promote normal tissue growth and repair, effect cardiac rate, and maintain the production of energy for muscles and body heat. Usually, ailing thyroids produce either too much or too little hormone. Overproduction is called hyperthyroidism; underproduction, hypothyroidism. Thyroid disease can develop gradually and imperceptibly, so one may have it for years and not know it. As with most illnesses, the outcome may be better if the diagnosis is made early.
   The more common thyroid ailments are Hashimoto’s thyroiditis and Graves’ disease. Both are autoimmune disorders- so named because the immune system attacks normal body cells, viewing them as foreign tissue. Hashimoto’s thyroiditis is six times more common in women than in men and it usually result in hypothyroidism. Grave’ disease is eight times more common in women and generally causes hyperthyroidism. If a medical examination suggests an underactive thyroid, tests for antibodies that attack the gland are usually ordered. On the other hand, if the test indicates an overactive thyroid, a thyroid scan is usually obtained, provided that the patient is not pregnant or breast-feeding.
  Hyperthyroidism usually cause excessive agitation, unexpected weight loss, rapid heartbeat, increase in bowel movements, irregular menstrual periods, irritability, anxiety, mood swings, protruding eye-balls, muscular weakness, insomnia, and thin, brittle hair.
  Hypothyroidism can lead to physical and mental sluggishness, unexpected weight gain, hair loss, and constipation, exaggerated sensitivity to cold, irregular menstrual periods, depression, voice change [hoarseness or low voice], memory loss, and tiredness.
   Proper nutrition can help to prevent thyroid problems. For example, does your food include sufficient iodine, which is essential for the production of thyroid hormone. Saltwater fish and other seafood are excellent sources of this vital element. The amount of iodine in vegetables and meats varies according to the chemical composition of the local soil. To compensate for a lack of the element in the food, some governments require that iodine be added to table salt.
  Also important to the thyroid is selenium. This trace element is part of the enzyme that transforms the hormone T4 intoT3. Again, the concentration of selenium in vegetables, meats, and milk depends on the soil. Seafood and Brazil nuts are rich sources of selenium. Of course, if you suspect that you have a thyroid problem, consult your doctor; do not try to treat it yourself.

WHAT YOU NEED TO KNOW ABOUT CHILDBIRTH



                          


     The nine-month wait is finally over, and the baby so longed for is about to be born. The expectant mother’s cervix has remained firmly shut, keeping the fetus safely in the womb. But now her cervix thins, softens, and relaxes. The miracle of birth begins.

    What is behind the marvelous process of childbirth? Of the several factors involved, two are especially amazing. First, OXYTOCIN, a hormone produced in the brain, is released. Both men and women produce this substance, but a great quantity of it is released in the pregnant mother when labor begins, causing the cervix to dilate and the uterus to contract.

     Just how the pituitary gland of the expectant mother knows when to begin releasing this hormones is a mystery. The book incredible Voyage- Exploring the Human Body states: somehow her brain senses that gestation is complete and that it is time for the powerful uterine muscles … to take on their brief but heroic job.

     A second factor involved in this process is the role of the placenta, which stops producing progesterone. During pregnancy, progesterone has prevented strong contractions. But now, without the restriction of progesterone, the uterus begins to contract. Generally after between 8 and 13 hours of labor, the baby is pushed out through the relaxed, dilated cervix. Afterward, the placenta is also expelled.

    Now the newborn must quickly adapt to new conditions of life, very different from those of its maternal environment. For example, while in the uterus, the lungs of the fetus were full of amniotic fluid, which was squeezed out when the infant passed through the birth canal. Now the lungs must be filled with air to initiate breathing, the onset of which is usually indicated by the first cry. Drastic changes also occur in the heart and the rest of the circulatory system. A hole connecting the two atria of the heart and a blood vessel bypassing the pulmonary circulation close, in order to reroute the blood through the lungs, thus enabling the blood to absorb oxygen. It is astonishing that this adaptation to the outside world happens so rapidly.

UNDERSTANDING SLEEP





   Most of the progress in understanding sleep mechanics has been made in the last 50 years. What has been learned explodes some long-standing misconceptions. One is the assumption that since many bodily functions slows down during rest; sleep is little more than a state of inactivity.

       By studying brain-wave patterns, medical researchers have learned that there are repeated cycles and stages of sleep. Far from being inactive, the human brain runs at high speed during certain periods of sleep. Healthful sleep involves going through these cycles four or more times every night and spending a sufficient amount of time in each cycle.

         A normal night’s sleep is most easily divided into 2 types: what is commonly called REM [rapid eye movement, or dream] sleep and non-REM [nondream] sleep. You can tell a person is in REM sleep when the bulge of his eyeballs can be seen rapidly moving under his eyelids.

        Non-REM sleep can be further divided into 4 stages. After lying down, you gently enter stage one –drowsiness or shallow sleep. During this stage your muscles relax and your brain waves are irregular and rapid. Its first occurrence each night typically lasts between 30 minutes and 7 minutes. When you move into stage 2 –true sleep –where you will spend 20 percent of the night, but you are unaware of your surroundings and cannot see even if your eyes are open.

         Next come stages three and four –deeper to deepest sleep. Here, in what is also called delta sleep, your brain produces large, slow waves. It is now that your body is most difficult to rouse, as most of your blood is directed to the muscles. During this time [usually about 50 percent of the night], body recovery and repair take place, and it is during delta sleep that young bodies grow. It is important to note that anyone, young or adult, who does not experience the deeper delta stages will likely feel fatigued, apathetic, or even depressed the next day.

        Finally, each cycle is completed by the radically different REM stage. During this dreaming stage [typically occurring about every 90 minutes], more blood is directed to the brain and your brain waves are almost the same as if you were awake. However, you cannot move your muscles. This immobility apparently keeps you from acting out dreams and hurting yourself or others.
        These REM, or dream, cycles get longer each time they occur during the night and appear to be crucial to mental health. In computerlike fashion, the brain sorts through short-term memory storage, deleting unimportant data and retaining what is desired for long-term memory. Abnormally infrequent dream cycles are known to result in emotional difficulties. Insomniacs, for example, spend less time than average in REM sleep, contributing to a vicious downward spiral of increasing anxiety.

       So, what happens when we are regularly deprived [voluntarily or involuntarily] of these repeated cycles, thus creating a sleep debt? If we get fewer consecutive hours of sleep than we need, we won’t get as much of the last and longest REM sleep period, which is vital to mental health. If our sleep patterns become irregular, consisting of a series of naps, we often don’t get to the deep delta sleep that is necessary to mend our bodies. Those in serious debt suffer from shortened attention spans, memory and vocabulary loss, a lessened ability to think analytically, and diminished creativity.

     What triggers the body to demand sleep? A number of factors evidently combine to create a circadian [daily] rhythm, or wake-sleep pattern. Brain chemistry appears to play a role. Also, there is a nucleus of nerve cells located in the brain that evidently helps control the sleep cycle. This “clock” is situated close to where the optic nerves come together. Light thus influences how sleepy we feel. Bright light wakes you up, while darkness induces sleep.

      Your body temperature is also involved. When your temperature is highest –typically midmorning and midevening –you are the most alert. As your body temperature drops, you become increasingly drowsy. Researchers agree that the pattern of wakefulness versus sleepiness varies with individuals

UNDERSTANDING OUT-OF-BODY EXPERIENCES



                                

 

               DÉJÀ VU gives us the feeling we have experienced an event before, even though this may seem to be an impossibility. Thus, the feeling of familiarity accompanying déjà vu is often unexpected and inexplicable, leading many people to wonder if their déjà vu experiences are psychic, physiological, or both.

         A number of mechanisms have been advanced to account for the déjà vu experience. Because psychic experiences of many kinds have been associated with déjà vu, it has often been suggested that déjà vu itself is a psychic experience. In this regard, déjà vu has been reported to be the result of reincarnation memories, subconscious memories of dream projections or out-of-body –experiences, subconscious memories of precognitive dreams, and clairvoyance. A higher frequency of déjà vu experiences have been reported for those who meditate frequently.

       Another proposed mechanism for déjà vu is that of biochemically encoded ancestral memories. This concept states that memories build up over generations into instincts, race memories, the collective unconscious, and all the materials that make up the totality of mind. Such a theory of memory, both personal and inherited, was advanced by C.G. Jung as a explanation for déjà vu. According to Jung, whenever an external event touches upon some subconscious knowledge, this knowledge can reach our objective consciousness. “The event is realized as déjà vu, and one remembers a pre-existent knowledge about it.”

                                                 BRAIN STIMULATION


       While the puzzling phenomenon of déjà vu has been reported in nearly all categories of altered states of consciousness, brain stimulation also achieves similar effects. Only a half-second’s stimulation in the hippocampal and amygdala portions of the limbic system. Lying deep within the brain’s temporal lobe, promotes déjà vu or familiarity as it is called by some researchers. Dr. Jose Delgado of Yale University noticed that patients stimulated in certain regions of the limbic system would listen to subsequent exchanges between themselves and the doctor with an air of amusement and bewilderment. “But this has all happened before. I knew what you were going to say before you said it.”
     Patients with temporal lobe epilepsy who frequently experience déjà vu are more likely to have lesions in the right temporal lobe. Coincidentally perhaps, the right hemisphere is non-verbal, and more intuitive and artistic than the left hemisphere.

        J.E. Orme of Middlewood Hospital in Sheffield, England, discussed the relationship of déjà vu to time theory in his scholarly work, Time, Experience and Behavior. He cited the work of R. Elfron, who found that the brain hemispheres do not necessarily process a message simultaneously. In a right-handed subject, a stimulus delivered to the left hand of the body is not available to the left hemisphere for two to six milliseconds after the right hemisphere receives the signal from the left side of the body. During the delay, the left hemisphere is unable to verbalize the sensation. The delay is the time it takes for the information to be passed to the talkative left hemisphere. If a lesion were to further delay the transfer, Elfron felt that maybe everything would appear to be happening twice, like instant replay.

                                                FEELING OF WONDER


           This speculation falls short of accounting for the subjective feeling that one is recalling the distant past. Also, the déjà phenomenon is sometimes accompanied by a wave of ineffable poignancy; the memory seems to be set in an emotional context. The psychic nature of déjà vu often leaves one feeling of wonder. This unique sense of wonder accompanied by familiarity is a hallmark of the mystical experience, and thus, the increased incidence of déjà vu frequently reported for meditators is not unexpected. During such mystical experiences déjà vu may also be accompanied by specific memories of precognitive dreams and visions. In these instances the specific dream memory may be of a metaphoric or symbolic character. For instance, one subject in our laboratory reported dreaming of a recently deceased pet who transformed into another personality that was not recognized by the dreamer at that moment. But soon afterwards, when a close friend with identical features to those of the dream personality unexpectedly died, the laboratory subject experienced déjà vu. He came to realize that the dream was helpful to others as well as himself, for the dream served to prepare them comfort during subsequent events.

          The brain mechanisms, while essential for the realization of such experiences as déjà vu, reflect a psychic process that lies deeper than the brain itself. The value of brain mechanisms, however, is that they allow us the opportunity to reflect more deeply upon the true nature of self
