										<content:encoded><![CDATA[<h3>Earth&#8217;s most abundant mineral identified</h3>
<p><em>Tschauner O. et al. Discovery of bridgmanite, the most abundant mineral in Earth, in a shocked meteorite. Science, November 2014.</em></p>
<p>A team of scientists has identified and characterized the Earth&#8217;s most abundant mineral: &#8220;Bridgemanite&#8221; makes up about 70 percent of the Earth&#8217;s lower mantle and 38 percent of its total volume. It is made of a high-density form of magnesium iron silicate and named after 1964 Nobel laureate physicist Percy Bridgman. For decades, scientists knew of the existence of dense Bridgemanite layers in the Earth&#8217;s lower mantle (660 to 2890 km beneath the surface) through theoretical and some experimental studies. However, since the mysterious mineral never survived the trip to the surface, no one had been able to prove its existence. Conveniently, shock-compression that occurs in collisions of asteroids creates an identical hostile temperature (2100 C°) and high-pressure (240,000 times greater than sea-level) conditions to those found in deep layers of the Earth. As such, scientists decided to look at meteorites closely, particularly one that had fallen in Australia in 1879. By using a micro-focused X-ray beam in conjunction with electron microscopy, they were able to successfully detect the Bridgemanite grains for the first time. The discovery of the Bridgmanite&#8217;s crystal chemistry will have a significant impact on the future studies of chemistry and geology of the Earth&#8217;s deep mantle, and perhaps studies on the formation of the universe.</p>
<h3><b>Male smokers lose Y chromosomes</b></h3>
<p><em>Dumanski et al. Smoking is associated with mosaic loss of chromosome Y. Science, December 2014.</em></p>
<p>The Y chromosome is one of two sex-determining chromosomes in men, who have one X chromosome and one Y (women have no Y chromosomes, but two X chromosomes). During normal cell division, copies of all of the 23 chromosomes, including X and Y, are synthesized and sorted into the two new daughter cells. This complicated process sometimes goes wrong and chromosomes are lost. Cells with missing chromosomes usually die, but cells can still survive without a Y chromosome. Scientists initially thought that men lose Y chromosomes as they age and this is a part of the normal aging process. But later studies have shown that the age-dependent loss of Y chromosomes can have serious health implications, as it is linked to a shorter life span and an increased risk of dying from cancer. Even more troubling results came from a recent study that screened for associations between behavioral and lifestyle choices, and diseases. Comparison of the DNA in blood cells of over 6000 men suggested that blood cells from actively smoking men are 3-4 times more likely to be missing Y chromosomes than the nonsmokers in the control. These findings may explain why male smokers have a slightly increased risk of death from the majority of cancers than female smokers. The scientists hypothesized that the Y chromosome loss may create defective immune cells that cannot fight cancer and ultimately make the body susceptible to tumors. The study gives some good news to smokers though. Y chromosome damage by smoking is both reversible and dose-dependent, so you are always better off not smoking; it is never too late to quit.</p>
<h3><b>The world&#8217;s oldest case of cancer</b></h3>
<p><em>Lieverse AR et al. Paleopathological Description and Diagnosis of Metastatic Carcinoma in an Early Bronze Age (4588+34 Cal. BP) Forager from the Cis-Baikal Region of Eastern Siberia. PLOS ONE, December 2014.</em></p>
<p>Cancer is responsible for one in four deaths in the Western world. It is widely assumed that cancer is a disease of modern times. Since people in older eras were exposed to fewer toxins, ate only natural foods, and adapted physically active lifestyles, many people thought that no one in older civilizations would have had cancer. Yet an analysis of a 4500-year-old skeleton from a cemetery in the Cis-Baikal region of Siberia has seriously challenged this idea. Researchers estimated that the Siberian man was about 35 to 45 years old before he died from a severe lung or prostate cancer. The ancient man&#8217;s bones, from head to hip and including his upper arms and upper legs, were covered by lesions and big holes. It is almost certain that the deterioration of his bones left him immobile and eventually caused him a very agonizing death. It is also clear that those around him recognized his situation and placed him in a circular grave in the fetal position with some artifacts ,which is completely different from the rest of the burials in the cemetery. Although ancient skeletons with the scars of cancer are relatively rare, scientists suspect that cancer may have been considerably more common in ancient times than is generally predicted, especially when considering other variables such as naturally occurring carcinogens and longer life expectancies.</p>

										<content:encoded><![CDATA[<p>It was an interesting dream. In ancient times, creatures that were destined for destruction questioned why they were given this sentence. What was the wisdom behind such a decision? How could it be just?</p>
<p>The answer was interesting and had deep meanings, but still left questions in my mind. The creatures were told: a new species will be created and arrive soon, and each member of this species will be equivalent and worthy of a whole species.</p>
<p><span id="more-1665"></span></p>
<p>Those who asked the question were silent, suggesting they were satisfied with the answer. But I wondered how a single member of a species can be worth an entire species – and whether destroying a whole species for a new one can really be just.</p>
<p>Here, it was obvious to me that the new species that would be created is humans, and those condemned were the species who went extinct in ancient times, before humanity appeared on earth. This dream vaguely reminded me something that I read in the &#8220;Risale-i Nur Collection&#8221; by Bediuzzaman Said Nursi.</p>
<p>Bediuzzaman remarkably states that, &#8220;A human being is equivalent to a species of other creatures&#8221; (Zuhra &#8211; 4th point, Isharat al-I&#8217;jaz, and Mathnawi al-Nuriya). This line hadn&#8217;t really struck me until I had the dream about older creatures questioning this wisdom.</p>
<p>In this dream, those creatures were dinosaurs. I was not scared; they weren&#8217;t threatening with their question. They were fighting for their rights and trying to understand the glorious plan, and beyond.</p>
<p>It seemed to me a lovely coincidence that I had a visit to Washington coming up soon and had a chance to visit the National Museum of Natural History, where you can see well preserved remnants of various dinosaurs.</p>
<p>All of the dinosaurs went extinct long before the first human showed up. Dinos first walked on earth over 200 million years ago and dominated the earth until 66 million years ago. Their dominion on earth ended with the Cretaceous–Paleogene extinction. According to fossil records, there were more than 1000 dinosaur species. Dinosaurs had different habits of eating, as some were herbivorous (plant-eating) and others were carnivorous (meat-eating), including fish-eaters and insectivores, and omnivores (including both animals and plants in their diets). We should be thankful that we never knew many of the carnivores like T-Rex, which measured up to 12m (40ft)! It&#8217;s obvious that we could not live on earth if T-Rex were still running around. For our arrival, their departure was necessary.</p>
<p>There is no doubt that the human species is very valuable from various aspects, but what puts each person on the same level with another species?</p>
<p>One of humanity&#8217;s great merits is our collective understanding. This collective consciousness can be more fully realized through the glasses of faith in God. With the window of faith, humans not only comprehend His speech, but are better attuned to their fellow living beings – and maybe even non-living creatures. Humans are like one who is that all-inclusive and hears all other things. Hence, we can grasp proofs of the most beautiful names of the Creator from the speeches of all creatures.</p>
<p>The light of such understanding in humans leads to an expansion and improvement in our soul. This makes our value high, our sight universal, and our ability to achieve to perfection limitless. On the other hand, many other species are limited in many aspects by their nature, sights, and capacity of perfection. According to religious texts, though humans and other species are valued differently on earth, the divide grows larger in the hereafter. While every human being is re-created with their names, features, matter, and manner, other species return back to the soil.</p>
<p>When you visit nature museum next time, try to listen what the fossils of extinct species tell you about their complaint. They were created for a purpose; they have finished their job and gone. They have done a fantastic job and flourished, while leaving us many petrol reservoirs. Though countless species have gone extinct, more than 1.6 million other species are still living on earth. Death is not an end; nowadays, they are trying to reach out to us and tell us their secrets. We&#8217;re expected to become the best fruit of this universe.</p>
<p>This dream made me think about how the ways that Allah could teach us is not limited to what we do when we are awake. Would you ever think that ancient extinct species would also need the lights of the everlasting speech of the All-Wise and All-Powerful, as explained by why a man could be equivalent and worthy of a species of another creature by Bediuzzaman?</p>
<p>Another lesson is that as we live in an oil dependent-century, we are counting on reservoirs that formed millions years ago by the remnants of ancient living beings; but just as we depend on them, ancient extinct species are also counting on us and expecting us to contemplate our purpose for being here, and to show that we&#8217;re worthy of being the most glorious fruit in the universe. As the All-wise make things with infinite wisdom, he sends oil to people of this century to help in technology and he also sends further mercy in the form of knowledgeable scholars to answer our questions.</p>

										<content:encoded><![CDATA[<blockquote>
<p><em>Though we cannot see humor, like faith, we perceive it all around us. </em></p>
</blockquote>
<p>Once upon a time there was a planet in an unknown corner of the vast universe. For a long time, this planet was distinguished by having inhabitants with no sense of humor at all! This sounds like a joke, doesn&#8217;t it? But I am here to tell history, not jokes. This planet&#8217;s history was studied in three eras, each having a different state of humor: the Ancient Period, the Middle Period, and the Modern Period.</p>
<p><span id="more-1571"></span></p>
<h3><b>I. Modern period </b></h3>
<p>The inhabitants of this planet were extremely serious, conscientious, sincere, hard-working, and moral. Besides all these good qualities, they considered humor as a pathological phenomenon. They never laughed or jested, kidded or joked. There was no room for any kind of humor.</p>
<p>A small minority, who had some feeling for humor, occasionally laughed and joked. However, their behavior was extremely alarming to everyone else. These few people were called &#8220;laughers,&#8221; and they were promptly hospitalized. What was so obnoxious about their behavior, aside from the strange noises they made and the peculiar facial expressions they bore while &#8220;laughing,&#8221; were the utterly pathological things they said! They seemed to lose all sense of reality. They said things which were totally irrational, indeed sometimes logically self-contradictory. In short, they behaved exactly like anyone else who was deluded or hallucinating, hence why they were put into hospitals.</p>
<p>More importantly, it was definitely verified that this &#8220;laughter&#8221; was somewhat contagious and that certain individuals became laughers for the first time in their life only after repeated contact with other laughers. Indeed, this was another thing which made the laughers so dangerous. They were not only hallucinating themselves, but tended to pass these hallucinations to others! Hence they had to be hospitalized, not only for their own sakes, but also for the sake of the society.</p>
<p>In the hospitals, doctors tried quite a number of different treatment regimens to cure their pathologic behavior. Besides many unsuccessful treatment attempts, one drug, called &#8220;laughazone,&#8221; was finally found to kill the symptoms of humor. Almost immediately upon administration, the patient would stop laughing as well as quit the verbal activity called &#8220;joking,&#8221; and would instead start screaming. The patient would just lie there screaming, hour after hour, day after day, week after week, and month after month. And the most amazing thing of all is that not once during this screaming period did the patient ever laugh or make a joke or even smile. They thought this drug was really phenomenal!</p>
<p>The problem with &#8220;laughazone,&#8221; though, was that its effects were temporary. After the months long treatment, the patient would, for some unknown reason, fall into a deep state of depression for several weeks, and sometimes longer. After this, he would gradually convalesce, and his original symptoms of laughing and joking would return. So, the doctors had to put the patient through the treatment again and again.</p>
<h3><b>II. Ancient and middle period </b></h3>
<p>The Modern Period contained no literature at all on laughter, except in textbooks and periodicals on abnormal psychology. The Middle Period, on the contrary, was chock-full of laugh-literature. This literature contained absolutely no material which contemporary laughers called &#8220;funny.&#8221; Indeed the writings were written in a wholly sane, serious, scholarly, and philosophic mood. The writings consisted mainly of analysis and commentary on the ancient texts. The ancient writings, unlike those of the middle period, were totally non-philosophical. They never spoke about laughter or anything like that. They were simply what the Middle Period called &#8220;funny.&#8221; These archaic manuscripts contained all sorts of incomprehensible and contradictory material called &#8220;jokes&#8221; or &#8220;funny stories.&#8221; Therefore, philosophers of the Middle Period extolled the Ancient Period, and referred to it as &#8220;the golden age of humor, when men could freely laugh and joke and really enjoy life.&#8221; Appreciating the ancient writings required a certain, almost mystical, faculty called &#8220;humor.&#8221; What was so puzzling was that humor could not flourish in the wholly serious and rational atmosphere of the Middle Period.</p>
<p>So, the Middle period witnessed many discussions on humor. One such discussion which had taken place between the mystic-humorists and the skeptical anti-humorists went as follows:</p>
<p>The Mystic-Humorists claimed that the only reliable way humor could be known was by direct perception: &#8220;We can see humor in many situations. Life is permeated with humor, if you can only see it.&#8221;</p>
<p>The skeptical Anti-Humorists said, &#8220;So, you claim you can see humor! Tell me, what color is it?&#8221;</p>
<p>The Mystic-Humorists laughed and said, &#8220;Humor doesn&#8217;t have any color!&#8221;</p>
<p>The skeptics continued: &#8220;Oh, so you can see it only in black and white! Well, then, what shape is it?&#8221;</p>
<p>&#8220;It doesn&#8217;t have any form or shape.&#8221;</p>
<p>&#8220;Then I am confused! Is humor visible or invisible?&#8221;</p>
<p>&#8220;Of course it is invisible!&#8221;</p>
<p>&#8220;But I thought you just said that you can see it. Didn&#8217;t you say that you could see the humor of certain situations?&#8221;</p>
<p>&#8220;Well, yes, I said that, but I didn&#8217;t mean &#8216;see&#8217; in the literal sense of &#8216;see with your eyes.&#8217; Ocular vision really has nothing to do with it. I used &#8216;see&#8217; in the sense of directly perceive, not see with the eyes. Perception, although as direct as vision, is really through a different sense altogether.&#8221;</p>
<p>&#8220;A different sense? Which sense is it &#8211; hearing? If so, what does humor sound like? Or is it smell or taste or touch or what? With which of the five senses do you perceive humor, or is it a combination of more than one of them?&#8221;</p>
<p>&#8220;No, it is not any one of these five senses, nor is it a combination of them. It is a totally different sense. In a way, it is a nonphysical sense. We call this sense the &#8216;sense of humor.'&#8221;</p>
<p>&#8220;Good God, you literally mean a nonphysical sense? In other words, you mean it is something occult, like telepathy or clairvoyance? But scientific integrity requires us not to believe in anything occult; hence we cannot but believe that this humor is something totally unreal, a mere figment of the imagination.&#8221;</p>
<p>In vain the Humor-Mystics protested that there was nothing the least bit occult about humor and said: &#8220;If only once you could see what humor was, you would realize that it is the most natural thing in the world, and also that it is delightfully pleasant.&#8221;</p>
<p>Another thing, the &#8220;Mystic-Humorists&#8221; claimed was that the label &#8220;Mystic-Humorist&#8221; was most misleading. They claimed that there was nothing at all mystical about humor, even though it might seem mystical to those who lacked the immediate sense of humor. They said, &#8220;Why not rather call us laughers, which is, in fact, what we are.&#8221; And so, the term &#8220;Mystic-Humorist&#8221; was gradually replaced by &#8220;laugher.&#8221; Later, this term would be used in the Modern Period as explained above.</p>
<p>Another discussion during the Middle Period was between the &#8220;laughers&#8221; and the Faith-Humorists, who believed that reason could be somewhat helpful in understanding humor but that an act of faith was crucial. Essentially, Faith-Humorists did not take a hostile, skeptical attitude toward the laughers, but instead believed in them wholeheartedly. They knew that the laughers were in direct contact with that which the Faith-Humorists could only reason about and accept on faith. However, they were heavily criticized by the &#8220;laughers&#8221; because of their approach to the issue:</p>
<p>You seem to think that knowledge about laughter is somehow more important than the ability to laugh.</p>
<p>You take an approach which is far too objective and scientific. You read all the literature you can find on the philosophy of humor. You perform elaborate linguistic analyses of what the word &#8220;humor&#8221; could possibly mean. The only way you will ever find out what it really means is by acquiring a sense of humor.</p>
<p>The most insidious error of all is to try to learn humor by merely imitating the outward forms of the laughers. You must remember that the activity of laughter is only a manifestation of humor. Humor itself is something entirely within the spirit.</p>
<p>Another thing that you do out of mere imitation is this ridiculous practice of memorizing jokes. You commit thousands upon thousands of jokes to memory and you think you are thereby acquiring a sense of humor! But memorizing these jokes is absolutely pointless for you until, and unless, you have acquired a sense of humor.</p>
<p>You combine the two techniques of joke memorization and forced laughter, and then you are sure you have matured. But God Almighty, how wrong you are! You go forth into the world claiming yourselves to be authentic laughers. Nothing sabotages our cause more than this! The skeptics who meet you are almost rightfully reinforced in their belief that humor is something which is a mere sham and delusion. Yes, the pseudo-laughers like you are the major cause of the disappearance of humor from this planet.</p>
<p>As laughter disappeared more and more from this planet, the people of the Middle Period realized that this was a tragic loss rather than a gain, and they did everything possible to stem the tide. Only at the very end of the Middle Period did it first occur to mankind that laughter, far from being something good, could actually be something totally undesirable. People started saying: &#8220;Maybe we should stop trying to stem the tide. Maybe the tide is our greatest blessing, although we don&#8217;t know it. Maybe it is high time that this silly archaic thing called &#8216;humor&#8217; should disappear. Maybe laughter was all right for savages, and we are now becoming civilized!&#8221; Then the idea fully occurred to mankind that humor was but another form of psychosis; laughter was a type of psychopathology. Thus was ushered the Modern Period.</p>
<h3><b>III. Back to the modern period </b></h3>
<p>As we discussed earlier, people of the Modern Period had to accept the painful fact that the laughers were not permanently curable, at least for the foreseeable future. This fact split the medical opinion into two divergent camps; hospitals, similarly, split into two widely divergent types. Hospitals of Type I were called &#8220;laugh-scream hospitals&#8221;; those of Type II were &#8220;pure-laugh hospitals.&#8221; In the laugh-scream hospitals, the doctors realized that no patient was permanently curable. Hence, once a patient was admitted, they were admitted for life. All that could be done was to administer the laughazone treatment over and over for the rest of the patient&#8217;s life. The discipline at these hospitals was ironclad: no patient was ever released, and there was to be no letup in treatment. It was better for the patient to face reality and scream than to withdraw into his fantasy world of humor and laugh.</p>
<p>The philosophy of the pure-laugh hospitals was, however, entirely different. They agreed with the laugh-scream hospitals that no laugher was permanently curable. But they thought: so why not let the patient enjoy his life? Was it really all that bad that he had these fantasies? Similar to the laugh-scream hospitals, patients were incarcerated for life. But they were given no treatments whatsoever! The patients in the pure-laugh hospitals were very happy. Everything possible was done for them to ensure their happiness. The pure-laugh hospitals, in the true sense of the word, were merely isolation centers. Their only function was to prevent the inmates from infecting the outside world with their laughter-psychosis.</p>
<p>Thus the conditions inside the pure-laugh hospitals were close to idyllic, except for one thing! Good God, the patients cried &#8220;How unfair that our brothers are screaming themselves to death in the laugh-scream hospitals while we are free to enjoy our laughter. Those doctors at the laugh-scream hospitals! They believe that they are helping their patients! They are the maddest of all! We must find a way to free our brothers so that they can enjoy laughter as we do.&#8221;</p>
<p>Occasionally, patients would escape from the laugh-scream hospitals, and they would immediately rush to the pure-laugh hospitals, where they were cheerfully admitted. As the patients in the pure-laugh hospitals increased in number day by day, at last, they managed to find the loopholes in the system. It didn&#8217;t take them long to organize raids on the laugh-scream hospitals, through which they freed all the laugh-wards, and brought all the patients back to the pure-laugh hospitals. The laugh-scream hospitals eventually went out of existence.</p>
<p>However, laughers were not satisfied with this success. They were bothered by the thought of those outside the laugh-communities who never knew the joy of laughter. What could be done for them? Just about nothing, they decided, since the old loopholes they had used to escape were taken care of. But here, providence intervened in a very remarkable way. What happened was this:</p>
<p>The standard of living inside the laugh-hospital communities was far higher than outside. One by one the outsiders pretended to be laughers in order that they might be incarcerated in the laugh-communities. The pretended-laughers knew perfectly that they had no sense of humor, and they couldn&#8217;t have cared less; they deliberately lied just for the purpose of joining the laugh-communities with their high standards of living. What happened was that the lying-laughers, being surrounded by an enormous majority of genuine laughers, very soon caught the laughing sickness themselves, and in but a few weeks turned completely into genuine laughers. And so one non-laugher after another lied his way into the laugh-communities, and shortly, became a genuine laugher. Then finally, even the psychiatrists succumbed, and no non-laughers were left behind. The entire planet was now one huge laugh-hospital, and the Modern Period that was devoid of humor became the funniest era ever.</p>

										<content:encoded><![CDATA[<p>Throughout history, humanity has been in search of eternal life; explorations into the deep galaxy and bio-medical projects in modern science are in one way dedicated to finding a new direction for this perpetual search. Doctor Luqman, the legendary figure of Eastern literature, was gifted with unique wisdom, which led him on a search for immortality. It is not certain whether this legendary Luqman is the same as the Luqman found in the Qur’an, but what they both share is the exceptional wisdom they were given “to be grateful to God” (31:12). One thing certain is that search for immortality and the idea of an afterlife has existed through the history of humanity. Belief in the Hereafter is the only reality that satisfies this inherent feeling. Bediuzzaman explains the benefits of believing in the Hereafter as follows:</p>
<p><em>It is only with the thought of Paradise that children, who form a great deal of humanity, can endure all the deaths around them, which appear to them to be grievous and frightening, and strengthen the morale of their weak and delicate beings. . . . It is only through the life of the hereafter that the elderly, who form another considerable part of humanity, can endure the proximity of the grave, and be consoled at the thought that their lives, to which they are firmly attached, will soon be extinguished and their fine world will come to an end. . . . It is only the thought of Hell-fire that checks the turbulent emotions of youths, the most vigorous element in the life of society, and their violent excesses, restraining them from aggression, oppression, and destruction, and ensuring that the life of society continues tranquilly. (The Ninth Ray, First Point) </em></p>
<p>If a society is deprived from the above benefits of belief in the Hereafter, people will try to find other ways to satisfy this search for immortality, as in the example of ancient Egypt. The fear of death and the desire for immortality are symbolized by the ancient Egyptian practice of mummification. The word “mummification” is derived from the Latin word mumia, meaning black bitumen. Bituminous materials were used extensively in the preservation of the body from the twenty-sixth dynasty of the Pharaohs onwards.</p>
<p>The ancient Egyptians believed that the body of a person was to live in the afterlife, therefore, mummification was developed; the total process took seventy days. Due to the expense of the materials involved in mummification, the pharaohs of Egypt, members of the nobility, and officials were the only people to be mummified, and they were usually buried in elaborate tombs. For religious reasons, some animals, such as baboons, cats, birds, and crocodiles were also mummified.</p>
<p>Mummies were placed in tombs that were designed to help the deceased live in the afterworld. The tombs were filled with all the necessities of life, such as food, tools, and treasures to ensure that the soul would return to the body, enabling the mummy to live happily.</p>
<p>The mummification process was used by many societies in an effort to cheat death and to achieve immortality. Modern society is no different from these ancient societies with respect to the desire to reach immortality. The only difference is the modern technology that is used to achieve immortality. Cryonics, a modern mummification technique, is a term that stems from cryogenic, the more general term given to the branch of physics that deals with extremely low temperatures. Cryonics is the practice of freezing the body of a recently deceased person to preserve it for possible resuscitation in the future. The body, which is in a state of “cryonic suspension,” is cooled to the point where molecular physical decay completely ceases. When a cure for the disease that caused the death has been found, the person may be revived and restored to good health later on.</p>
<p>This is not a new idea. In early 1967, a California psychology professor named James H. Bedford decided to try it. When he died of cancer, he was frozen in liquid nitrogen at 321 degrees below zero Fahrenheit. After Bedford, over a period of a few years, several dozen people were frozen in liquid nitrogen. After a while, the relatives stopped the flow of money to the cemetery crypt in Chatsworth, California. By 1987, the frozen bodies, one of those being the body of Bedford, kept in liquid nitrogen had dropped to only three in the United States, due to financial reasons. By 1994, the number of frozen bodies once again had risen, climbing to about a dozen. Another two dozen had chosen the cheaper alternative of having only their heads frozen after death. They believed that future technology would be able to provide a new body by using their DNA. Cryonics organizations have been growing rapidly, with several hundred people now being legally signed up to be frozen after death.</p>
<p>The type of death is very important for cryonics. Real death and legal death are not the same things. When it is no longer feasible to restore the blood circulation (i.e. restart the heart), legal death occurs. Real death occurs after the cells have irreversibly deteriorated in the minutes and hours that follow. Due to the fact that so much cellular information is lost after real death, cryonics begins after legal death has been declared.</p>
<p>After legal death, the body is hooked to a heart-lung machine to supply oxygen to the still living tissues. At the same time the blood is drained and some chemicals are circulated to minimize the damage caused by freezing. To protect the body, all chemical reactions are stopped by hindering translational molecular motion. This motion is stopped at 130 degrees below zero Celsius, that is “glass transition” temperature. The human body is cooled to the temperature of liquid nitrogen, -196 degrees Celsius (-320 degree Fahrenheit). The bodies are then placed in a vacuum-insulated flask, head down, so that in the event of a problem it would be the feet that would thaw first. While to date no human being in cryonic suspension has been revived, it has been proven that the bones, the skin, some tissues, the red and white blood cells, the bone marrow, human embryos, and sperm survive under deep freezing and thawing.</p>
<p>Some special techniques are used to reduce the damage caused by freezing. Using a procedure called vitrification, a mixture of cryoprotectant (antifreeze) compounds replaces more than 60% of the water inside the cells to prevent the tissue from freezing during cooling; the tissue becomes rigid like glass, with no ice crystal damage. On the other hand, high concentrations of cryoprotectant are toxic to cell metabolism. It is hoped that this problem will be solved and reversed in the future by nanotechnology. Nanotechnology is the technology that has been developed in order to work with atoms and molecules in the future. By using this technology, the damage in the cells caused by freezing will be able to be repaired. In addition to nanotechnology, therapeutic cloning developments and stem cell research discoveries will be important in making cryonics successful. Taking into account the speed of the development of these technologies, some experts have estimated that it will take 20-100 years before humans can be successfully thawed out.</p>
<p>Such a process requires a great deal of money; it is not cheap to freeze oneself for future life. Prices range between a fee of $28,000 to $120,000 annually. By freezing merely the head, this price can be reduced by half.</p>
<p>Be it the ancient mummification methods, be it the latest expensive techniques, all these point to the unchanging human nature. Cryonics try to reach immortality in “this life”; however, this is an impossibility with today’s technology and is merely speculative with future technology. But there is a way that is possible now, and does not require great expenditure or mind-boggling technology. Bediuzzaman, in his book, The Rays, explains how we can achieve such immortality:</p>
<p><em>For example, human beings have an intense desire for immortality. Only One Who has disposal over the whole universe as though it was a palace can answer this wish; only One Who can close the door of this world and open that of the hereafter, like closing the door of one room and opening that of another can do so. Humans have thousands of desires, both negative and positive, which like the desire for immortality spread throughout the world and stretch to eternity. It is only the Single One, Who through the mystery of unity holds the whole universe in His grasp, Who, by answering these desires of human beings, can cure the two gaping wounds of impotence and want. </em></p>
<p>In other words, the ability to find immortality is something that has always been with us; it resides within us. The ancient Egyptians and modern science both spent large sums of money and much time trying to attain immortality; if only they were aware that every human has the same chance. All we need to do is to just look within ourselves</p>

										<content:encoded><![CDATA[<p>God created thousands of flowers, and yet roses have remained a favorite throughout human history and have assumed very colorful meanings among different cultures. Why does the rose find an enduring place in our hearts? Maybe we retain the memory of a rose found in the garden of our soul. Perhaps unforgettable poems, as well of stories of love and virtue, are attached to the rose. Perhaps the quality of one perfect bloom fills and uplifts our spirit with the soft light of morning. Or, maybe its scent has so much strength that it just cannot be denied.</p>
<p>Even though garden cultivation of roses began some 5,000 years ago, possibly in China, the fossil record indicates that roses have existed for millions of years. Wherever roses are found, they become a symbol of something: love, beauty, royalty, death, war, and politics. Sometimes, they even represent famous names in history.</p>
<p>During the Roman Empire, roses were grown extensively in the Middle East. Those roses, the most fragrant in the world, were used to make perfume. Their strong scent also caused people to regard them as having a deep mystical significance. However, roses grown in China do not have such a scent. Perhaps this is one reason why roses are not nearly so beloved in China.</p>
<p>Roses seem to make their first literary appearance in the eighth century bce. In The Iliad, an epic poem of ancient Greece, Hectares body was anointed with rose oil. Roses are often mentioned in ancient Greek myths in a wide variety of different forms. For example, a white raised symbolized Aphrodites purity and innocence. Furthermore, her desire and passion for Adonis, her wounded love, was represented by a few drops of her blood changing a white rose into a red rose. In another myth, Zeus scattered roses across the land as a wedding gift to Eros and Psyche.</p>
<p>The Romans also embellished their myths with roses. They used roses at funerals as a sign of resurrection, for example, and Flora was the goddess of spring and flowers. Despite being credited with creating the rose, other Greek deities helped Flora give it its life, sweet scent, and beautiful shape.</p>
<p>Presumably, a correlation exists between ancient Greek and Roman mythology and Christianity with respect to roses. Harpcrates, who was bribed into secrecy with a white rose by Eros, became the god of silence. This was carried over into Christianity, for a rose was often carved onto a meeting rooms plastered ceilings to warn that the discussions were sub rosa (under the rose, or secret).</p>
<h3><b>The rose and religion</b></h3>
<p>Christians used the red rose as a symbol of Jesus passion, martyrdom, and resurrection, as well as for Marys motherhood and purity. Mary is mostly linked with the white rose. The roses design also implies the liturgy. For instance, Mary is surrounded with brilliant roses in this beautiful poem by Wordsworth (1807):</p>
<blockquote>
<p>In trellised shed with clustering roses gay,<br />And, Mary! Oft beside our blazing fire,<br />When yeas of wedded life were as a day<br />Whose current answers to the hearts desire.(1)</p>
</blockquote>
<p>Also, Mary is often reported as being accompanied by showers of fragrant rose petals. Many stained-glass window scenes of the Blessed Mother and other saints show them holding roses. Underlying all of this is the idea that fragrance is good.</p>
<p>In the seventh century, Prophet Muhammad is symbolized with a rose. It seems that every opening bloom points to another wonderful person in the garden of humanity. The roses reputation increased a thousandfold with the coming of the Prophet. His great personality illuminated the roses color, and his perfect morality is the source of its fragrant sense.</p>
<p>Farid ad-Din Attar (d. 1230), one of the greatest Sufi mystic poets of all time, wrote in his The Rose Garden:</p>
<blockquote>
<p>In the rose bed, mystery glows.<br />The secret is hidden in the rose.(2)</p>
</blockquote>
<p>Another Sufi mystic, Hazrat Inayat Khan (1882-1927), notes that just as the rose consists of many petals held together, so a Sufis soul shows many different qualities. These qualities emit fragrance in the form of a spiritual personality. As the rose has a beautiful structure, the Sufi has a fine structure, manner, dealing with others, speech, action, and so on. Just as the roses beautiful perfume penetrates the entire room, the Sufi penetrates society and helps to heal its problems.</p>
<p>Furthermore, the Quran honors the red rose by mentioning only it out of all flowers: When the sky is torn apart, so it was (like) a red rose like ointment. Then which of your Lords favors will you deny? (55:37-38). The beauty of a single rose is just one small creation among all of Gods bestowed bounties. The rose has a distinct shape, and whoever created it and tore the sky apart, just like we might tear apart a red rose, created it so that we could understand that the rose was created for significant reasons.</p>
<p>In the Islamic tradition, wearing perfume is a food for the soul and the spirit. One hadith relates that one of the Prophets favorite things was good fragrance. That is why Muslims often wear pure essence of rosewater, especially before prayers. Rosewater is also the preferred soak for the miswak (a traditional toothbrush taken from the branches of a fibrous tree).</p>
<p>Possessing one of the most heavenly scents, a roses essence has several aromatherapeutic benefits as well. Valerie Worwood, in her The Complete Book of Aromatherapy, writes that a roses essence is a powerful and uplifting anti-depressant, aids in digestion, and soothes frayed nerves. These benefits can be enjoyed just by sprinkling some rose water or essence on your body, adding a few drops to your bathwater, or burning the scent in an incense burner in your home.</p>
<p>Associating roses with religion is as old as religion itself. How nice it would be if the veneration that all Jews, Christians, and Muslims have for the rose could make all of us understand that we are bound together with each other and many others in this very way! Moreover, these three monotheistic religions trace their origins to the Middle East, the ancestral home of modern roses.</p>
<h3><b>The rose in other cultures</b></h3>
<p>Many other cultures feature things related to the rose. For example, different sects within Hinduism worship deities through such household and temple offerings as rose attar (perfume). Ancient Persian legends speak of a nightingale that so dearly loved the white rose that it grasped it tightly. The thorns, which pierced its breast and caused its blood to fall on the rose, turned it red. Hence, one type of rose is known as the red damask. Interestingly, Rose is one of the most popular names for girls in many languages. The Turkish word gul, for instance, means rose and smile and has many popular derivations in Turkey.</p>
<p>Around the twelfth or thirteenth century, knights returning from the Crusades brought the rose home to Europe. By the middle of the fifteenth century, the rose was used as a symbol for the factions fighting to control England. The white rose symbolized York, and the red rose symbolized Lancaster. As a result, the conflict became known by historians as the War of the Roses. The red rose is still the emblem of England, since Lancaster won the war. Roses were in such high demand during the seventeenth century that royalty considered roses or rose water as legal tender. Both were often used as barter and for payment. Napoleons wife Josephine established an extensive collection of roses in western Paris during the 1800s.</p>
<h3><b>A new interpretation</b></h3>
<p>In the twentieth century, a splendid new interpretation of the rose and nightingale story was presented by Bediuzzaman Said Nursi. His famous The Words contains an addendum to the discussion on the nightingale. The nightingales small wage is the delight it experiences from gazing on smiling, beautiful roses, and the pleasure it receives from conversing with them and pouring out its woes. In other words, its sorrowful song is not a complaint arising from animal grief; rather, it is the birds thanks for the gifts of the Most Merciful.</p>
<p>Moreover, according to Said Nursi, every sort of being&#8211;even stars&#8211;has a nightingale. But the most excellent and noble nightingale, whose voice was the most ringing, whose recitation was the most complete, whose thanks were the most universal, who brought all beings of the heavens and Earth in the universes garden to rapture through his poetry was Prophet Muhammad, the nightingale of the luminous Quran. Here, the rose is associated with divine knowledge and wisdom.</p>
<h3><b>Conclusion</b></h3>
<p>Today, people prefer to buy roses for special occasions as precious gifts. As Shakespeare said, there is a meaning kept in the rose that we have to understand, just as the rose keeps its scent within itself. On Valentines Day roses express our love, on Mothers Day they tell our mothers that we remember their mercy toward us, and on Teachers Day they show a students respect for his or her teachers.</p>
<p>Most modern-day roses can be traced back to this symbolic ancestry. The popularity of roses seems to rise and fall according to gardening trends of the time. Gardeners realize that roses fit the lifestyle of every century. With the rise of emphasis on spirituality in the twenty-first century, roses are once again enjoying a resurgence in popularity.</p>
<p>Roses have a special hold upon us and, even though it is hard to capture in words, there is something about roses that evokes a response beyond the virtue of great beauty. This article has presented some historical traces of roses in several civilizations. Perhaps you will associate them with a favorite meaning or figure. So, would you like to finish the following sonnet of Shakespeare in your own way?</p>
<blockquote>
<p>I have seen roses damasked, red and white,<br />But no such roses see I &#8230;?(3)<br />(the original says in her cheeks)</p>
</blockquote>

										<content:encoded><![CDATA[<p>Media interest in cloning dinosaurs lasted a couple of months following the adaptation of Michael Crichton&#8217;s best-selling novel Jurassic Park as a Steven Spielberg film. The spring of the plot of Jurassic Park is the preservation of DNA in ancient amber. DNA is neither the only, nor the most widely preserved, molecule in fossils. Other organic molecules such as proteins, carbohydrates, lipids and more complex biopolymers, have a higher potential for preservation than nucleic acids.</p>
<p>Because of their biochemical importance, the nucleic acids receive much more attention than the others. DNA was first isolated in 1869 by F. Miescher from cell nuclei. Nearly 80 years of research have been carried out to identify the major building block units and the basic structure of nucleic acids. DNA molecules from different cells and viruses vary in ratio of the four major types of nucleotide monomers, in their nucleotide sequence, and in their molecular weight. Four major bases (adenine, guanine, thiamine, and cytosine) are found in all DNA. The DNA isolated from different organisms and viruses normally has two strands in complementary double-helical arrangement, and it is the basic compound of genetic material (chromosomes). In its double-helical structure it has a 20 A (1 A=10-8 cm) diameter width and the nucleotides are repeated in every 3.4 A.</p>
<p>This polymeric molecule, DNA, is the chemical basis of heredity and is organized into genes, the fundamental units of genetic information. It was first demonstrated in 1944 in a series of experiments that genetic determination of the character (type) of the capsule of a specific pneumococcus could be transmitted to another of a distinctly different capsular type by introducing purified DNA from the former coccus into the latter. This agent (later shown to be DNA) was called &#8216;transforming factor&#8217;. Subsequently ,this type of genetic manipulation has become commonplace. Similar experiments have recently been performed utilizing yeast, cultured mammalian cells, and insects and rodents as recipients, and cloned DNA as the donor of genetic information.</p>
<p>DNA has the ability to replicate itself. It is this property that holds the genetic material in the same type and number sequence during the cell divisions. In prokaryotic cells, which contain only a single chromosome, essentially all the DNA is present as a single double-helical, two-stranded macromolecule exceeding 2 x 10- 9 in molecular weight. In eukaryotic cells, which contain either several or many chromosomes, there ate either several or many DNA molecules. </p>
<p>The double-stranded structure of DNA can he melted in solution by increasing the temperature or decreasing the salt concentration. The denaturation of DNA is used to analyze its structure. Not only do the two stacks of bases pull apart but the bases themselves unstack while still connected in the polymer by phosphodiester backbone.</p>
<p>Careful examination of the model reveals a major groove and a minor groove winding along the molecule parallel to the phosphodiester backbone. In these grooves,proteins can interact specifically with exposed atoms of the nucleotides (usually H bonds) and thereby recognize and hind to specific nucleotide sequences without disrupting the base pairing of the double-helical DNA molecule. As easily seen, regulatory proteins can control the expression of specific genes via such interactions.</p>
<p>The genetic information stored in the nucleotide sequences of DNA serves two purposes. It is the source of information for the synthesis of all proteins of the cell and organism, and it provides the information inherited. Both these functions require that the DNA molecule serve as template &#8211; in the first case for the transcription of the information into RNA and in the second ease for the replication of the information into daughter DNA molecules.</p>
<p>DNA is likely to survive for millions of years in some conditions. Amber can provide some of the right conditions to preserve DNA. The most reliable report of DNA to date from amber is that of termite-like sequences from around 30 million year-old Dominican amber. The earlier recovery of DNA from a 20 million year-old magnolia leaf, near Moscow, was more remarkable because the leaf was preserved in a sequence of easily split soft clays and silts, interbedded with layers of volcanic ash.</p>
<p>Recent developments in genetics are providing very powerful new techniques for the analysis of DNA from remains of ancient organisms. The young field of ancient DNA research is less than a decade old but is growing exponentially. In spite of some serious technical difficulties, the study of ancient DNA promises to become a revolutionary research tool in archaeology; anthropology and molecular biology.The earliest report of retrieval of informative DNA sequences from extinct animals &#8211; in this case from the desiccated skin of a quagga, a member of the horse family which became extinct more than one hundred years ago &#8211; was that by A. Wilson and his colleagues in 1984. Shortly after this, DNA was isolated by S. Pbo from the skin of a pre-dynastic Egyptian mummy; it was shown by DNA hybridization that a small amount of recognizable human DNA was left in the ancient tissue. In 1988, the first report of an amplified ancient DNA sequence was made by S. Pbo and colleagues who retrieved it from a 7,000 year-old skull found in a peat bog.</p>
<p>It seems likely that studies of this kind will become even more popular in the near future. With the ancient DNA sequence studies, one of the most controversial problems in biology &#8211; evolution &#8211; will possibly be enlightened. No there is a drive to gather genetic information from indigenous groups to increase our understanding of human origins, history and migrations. Ancient DNA studies will play a very important role by providing a direct source of objective evidence on past populations, and perhaps the only reliable insight into the genetic characteristics of vanished peoples.</p>
