Robots continue to advance and develop every year, and these consistent improvements continue to amaze us with how much they physically resemble humans. Even though these robots lack spiritual qualities and function way below the human brain, we still admire these developments, for they lead to even more discoveries and help us understand the miraculous human body even more.

Notwithstanding our medical knowledge that continues to build upon nearly 3,000 years of shared human experience and research, new discoveries about the human body, the magnificent work of God Almighty, continue to increase our admiration.

The discovery of the “Interstitium” and the “Subcapsular Proliferative Foci” in 2018 allow us to develop an even greater appreciation for the complexity of our bodies. They are called the “macro organ” and “micro organ” according to the amount of space that they occupy in our bodies, along with the nicknames “buffer organ” and “control center organ” according to their function. These newly discovered biological structures did not attract much attention earlier because, in accordance with our current understanding, organs are more easily visible structures such as the hands, arms, eyes, nose, kidneys, and lungs that have a certain shape and a set of clearly-defined functions. It is interesting that although these complex structures are so widespread in our bodies, they were not known until recently; they are now considered as organs [1].

The Macro Organ: Interstitium

According to an article published in Scientific Reports on March 27, 2018, the “interstitium” was discovered rather serendipitously by David Corr-Loce and Petros Benias of Mount Sinai Beth Medical Center along with Neil Theise, a pathologist from New York University. The discovery came when these physicians were analyzing a cancer patient’s bile duct. Although they had been conducting the same routine over the years, it was the first time they had the sight of slots between examined tissues. They realized that the interstitium was unnoticed earlier due to the disappearance of interstitial fluid after they had examined the tissue with their usual histological methods. Subsequently, the researchers found that this structure was found not only in the bile duct but also in many other organs.

Specifically located under our skin, these micro-compartments were also found in almost all organ membranes except the intestines, lungs, veins, and muscles in order to form a network around the organs with malleable but sturdy proteins. The interstitium, the entirety of the intercellular spaces filled with liquid, has been defined as the largest organ in the body. Actually, examining cells and tissues has been the subject of histology and cytology science for the last 150 years, and the fluid that fills the tissues and forms a basis for supporting these cells was not new to the medical world. However, its definition as a new organ was a first.

The researchers froze the biopsy tissues obtained from the bile ducts of 12 patients in order to preserve and examine the anatomy of the discovered structure. One of the reasons that this organ exists is because it protects the surrounding organs by acting as a shock-absorber and has an effect similar to that of a car’s bumper. Damage to tissues and internal organs remains minimal when one falls, hits something or is impacted Using a micro-endoscopic camera, the volume of this whole organ was revealed to be about ten liters in an adult human [2].

It was later discovered that the interstitium is also present in the structure of lymph nodes, the most important part of the body’s immune system, and that cancer cells enter the lymphatic system through the interstitium. In this case, the interstitium play a significant role as a passageway, or conduction interface, for spreading cancer cells across the body. In an analogy, this organ is akin to the water in which fish swim, the air that surrounds us, and the soil that borders the roots of trees. In this liquid that rotates the cells and spans on the base where they are positioned, any exchange of substances of body biochemistry is regulated within the required amount and size to provide a good setting to the cells, and the hard mechanical effects that may impact the cells are alleviated and absorbed by this liquid pad.

Each discovery of the interstitium’s features, including its significant contributions in the fight against cancer, reveals more and more about how this great organ aids in intercellular communication.

The Micro Organ: Subcapsular Proliferative Foci

One of the most important features of the immune system is that it has its own “memory.” The cells of the immune system can remember the infections a person has contracted before, and can fight infections before they spread. How quickly the immune system reacts based on memory may vary, for instance depending on the type of infection, but is usually quite rapid. Considering how many bacteria multiply in a matter of seconds, a quick response must be launched to prevent infections from spreading across the body.

Professor Tri Phan of the Garvan Medical Research Institute led the team of researchers that discovered the subcapsular proliferative foci (SPF), a “micro-organ” that appeared in the lymph nodes during an infection. Lymph nodes and lymphoid organs such as tonsils, thymus, and spleen are surrounded by a protective capsule made of connective tissue. This capsule was considered to serve the purpose of a mechanical support only to enclose and protect the lymph nodes. However, recent research has shown that in some areas under this capsule, cells that had been alerted to previous encounters with harmful invasive organisms are gathered. These main subcapsular cells are memory B cells that carry information on how to counter the invasive organisms. Memory B cells also proliferate into plasma cells, which are highly important for producing antibodies. Therefore, when an infection reoccurs in our body the subcapsular proliferative foci act quickly to form the first defensive front to prevent the possible spread of infection.

The purpose of vaccines is to activate the attenuated form of a harmful organism to be stored in the body’s memory as an immune response. If the body comes back into contact with similar bacteria in the future, the immune system will remember how to fight it. The discovery of the sub-capsule foci also revealed that these centers are the home for the memory B cells. If they can unveil the development and training processes of the memory B cells in these slots, scientists can produce vaccines that enhance the memory of the immune system even more quickly and efficiently.

The reason why these structures have not been noticed earlier is due to their emaciation, brief emergence, and disappearance. The sub-capsule proliferation centers presented in the article “Memory B Cells Are Reactivated in Subcapsular Proliferative Foci of Lymph Nodes” published in Nature Communications on August 22, 2018 are defined by some authoritative scientists as the “micro-organ.” According to the findings about this new organ, if our infection-fighting immune system would have activated longer than it currently does, we would easily die. Every minute is very crucial in this struggle. These excellent centers that produce memory cells under the lymph node [3] capsules fight bacteria which can replicate in multitudes every 20–30 minutes during an infection.

Although the world of science has been working with the microscope for about 400 years, these centers that have been embedded in our body since its creation could only be noticed today when the microscope design has reached its technological peak.

There are trillions of bacteria living in the intestinal cavity, skin, and orifices of our body. Some of these are already protective and beneficial, yet others are pathogenic. But they do not make us sick because of B cell production centers. When our immune system is weakened for any reason (such as stress, insomnia, or malnutrition) these bacteria can cause illnesses and meet little resistance. These sub-capsular micro-organisms surrounding the lymph nodes were placed in the most strategic places across the human body to fight infections in the fastest way, while the lymph nodes were placed at locations that are most vulnerable to microbial attack.

Consequently, these discoveries increase our admiration for the palace and magnificent realm called our body. It is likely in the light of this information that the anatomy and histology books may be rewritten and the definitions of organs and tissues may be redefined.

Fear of obesity may sometimes lead people to an extreme diet, and this may cause a deadly disease: anorexia nervosa. The sufferer initially tries to lose weight by going on a diet, but the illness soon reaches the point of no return as the result of extreme dieting. At this point, weight loss cannot be stopped; the person can no longer eat, even if he or she may want to. If they do manage to eat a little food, they throw it up. This disease and many other health conditions are connected with how our bodily functions like appetite are regulated with the secretions in our brain.

Discovered in 1998, orexin is a neuropeptide, or protein-like substance secreted by the brain. It is responsible for regulating states like wakefulness, appetite, and arousal. There are tens of thousands of neurons in the lateral hypothalamus of the human brain that secrete orexin. It was first discovered to increase appetite, but later other functions – especially in relation internal organs – were identified, including regulating the body’s energy use.

Orexins play very important roles in the development and maturation of the brown adipose tissue, which is especially important for infants. The fats in this tissue are directly converted into heat. It is the duty of the adipose tissue to protect the body from illnesses in cold weather. Experiments on lab rats have revealed that body temperature decreases in animals without orexin in their body, and they fail to consume fats. The conclusion is that orexins help boost energy consumption, protect the body from cold-related illnesses by raising the body temperature, and prevent obesity.

Orexins also help regulate metabolic activity and its speed. They are also responsible for regulating the circadian rhythm, or the daily sleep-wake cycle, especially by helping us stay awake. Orexins help increase the secretion of dopamine, norepinephrin, histamine, and acetylcholine hormones, which are in charge of the proper functioning of the daily sleep-wake cycle. All these hormones are substances that increase wakefulness.

The destruction of neurons responsible for producing orexin leads to a severe illness called narcolepsy, which is a serious sleep disorder. Patients suffer from sudden fits of involuntary and extreme sleepiness, irregular nighttime sleep, sleep apnea, various hallucinations, and muscular paralysis called cataplexy. They may suddenly fall into REM asleep while driving and watching television. The muscular paralysis accompanied by REM sleep makes sufferers collapse wherever they may be. They sometimes cannot move and remain motionless, even when they wake up. The fits of sleep strike with or without forewarning and make the need for sleep impossible to fight off. Since frequent uncontrollable collapses may cause injury, narcoleptics know they have to take precautions when they perform daily tasks. Generally appearing in a person’s twenties, the disorder may result from organic factors such as inflammation or a tumor in the brain or other underlying hostile causes.

Narcolepsy is untreatable. It can sever patients from real life and incapacitate them, leaving them unable to perform routine daily tasks. Treatments that are available can only make patients’ lives bearable.

Cataplexy is a condition in which muscles become dysfunctional, speech becomes incomprehensible, and the body collapses due to loss of strength in the neck or knees. Fits may also appear in the form of emotional responses such as excessive laughter, anger, or fear. The duration of cataplexy may last from a few seconds to a few minutes. Patients do not become unconscious during the attack; they just lose control of their physical functions. More often than not, people who have a cataplexy attack in public places seem to be under the influence of alcohol or drugs. They can see and hear others, but they cannot respond.

Sleep paralysis is a temporary state of inability to speak or move during sleep. Although it may look frightening, it is in fact not dangerous. Hypnotic hallucinations, on the other hand, are extremely vivid and frightening dream-like states experienced when falling asleep or waking. An extreme tendency for daytime sleep and hypnotic hallucinations are consequences suffered by people who have not had enough sleep, whereas cataplexy is unique to narcoleptic patients.

Orexins are also responsible for increasing the amount of nutrition a body consumes. This duty is not about meeting the body’s daily diet. Orexins tend to increase appetite, even when the body does not need feeding. They suppress the feeling of satiety, causing the person to continue eating. The willpower should kick in at this point, and the person should use it to stop eating.

The secretion of orexin is influenced by two opposite hormones. The first is leptin, secreted in obese people. Leptin’s duty is to prevent the person from overeating by reducing orexin secretion. The second is ghrelin, a digestive hormone secreted when the stomach is empty. Ghrelin increases orexin secretion, causing an increase in appetite.

It has also been discovered that orexins are connected with smoking and drug addiction. Medicines that reduce orexin secretion are used in addiction treatment. Orexins stimulate the neurons of pleasure in the brain, the reward centers, and impact a person’s happiness or sadness. A reduction in orexin secretion leads to unhappiness and sadness.

Despite that, there are more than 100 types of amino acids found in nature; only 20 of them are employed for protein synthesis. Among these 20 amino acids, excepting glycine, which does not display chirality, only the L-form of the 19 is used for protein synthesis. This is because ribosomes, where protein synthesis occurs, do not feature the utilization of D-form amino acids. As nothing in the universe exists in vain but with multiple tasks, D-amino acids have a job in the maintenance of life after protein synthesis in very different fashions. The way D-amino acids are employed in the execution and control of physiological preferences amazes scientists.

Up until recent times, D-amino acids were believed to be synthesized mostly by bacteria and plants, unlike mammals, and were considered dysfunctional as they passed, via consumption of nutrients, from bacteria and plants. However when D-amino acids were noticed for having roles as important as L-amino acids during the 1990s, the field gained significance. It was demonstrated that D-amino acids were found widely in invertebrates, vertebrates, and humans as free forms or inside proteins, undertaking critical functions in the nervous and endocrine systems. The most interesting point is the conversion of amino acids from the L-form into the D-form after the protein synthesis occurs in the peptides that are present in the venomous secretions of various animals. This conversion leads to the alteration of the peptide identity and function. Racemase and isomerase (epimerase) enzymes are utilized as they are created for this task. Usually, one or two amino acids of the D-form peptides are in D-form.

When chemist Gunther Kreil of the Austrian Academy of Sciences learned about the use of South American poisonous tree frogs (Phyllomedusa sauvagei ) during Shamanic hunting ceremonies by local Peruvian tribe (Matses), he studied this poison in detail. Participants of the ceremony first caused a burn on their chest region, then applied the poison they obtained from the frog skin over it. Diarrhea and tachycardia started within a minute, followed by a brief faintness. Once they recovered after a few minutes, they were to find themselves in a much more vigorous and exhilarated state of mind. The poison they were applying to their chest contained the dermorphin peptide, which has psychoactive, hallucinogenic effects and a D-amino acid. This peptide is a pain killer 30-40 times more effective than morphine. Among the 7 amino acids found in this peptide (heptapeptide), all are in L-form, except for one. Only the alanine, as the second in the peptide sequence, is in D-form and is produced via the isomerase enzyme from the L-alanine after the protein synthesis. G. Kreil discovered this D-form synthesizing enzyme in 2005. When this peptide was synthesized artificially in the laboratory, it did not display any biological activity or hallucinogenic effect. After a careful investigation of the case, it was found that frog skin based peptide had a D-form alanine second in its sequence; however, the one produced in laboratory had an L-form alanine. It was the presence of only one D-amino acid that made the difference in discovering the identity and function to the natural peptide in the poison.

In recent years dermorphin has started to be used as an illegal performance enhancer during horse races because of its pain killer feature. Horses on dermorphin can run longer and faster since they cannot feel the pain related to foot fatigue.

P. Kuchel of Sydney University also showed a D-amino acid presence in the peptide structured of the poison in the Platypus, a semiaquatic egg-laying mammal. Males use this poison as a weapon to fend off competitors. In 2009, Matthew Waldor and his friends at Harvard University discovered that the sugar-protein mix (matrix) called peptidoglycan found in the composition of bacterial cell walls is structured in a way to contain primarily D-alanine, D-methionine, and D-leucine. More interestingly, D-amino acids of the peptidoglycan structure were able to play a stimulatory role in coordinating the activities of other bacteria in the colony. For example, they acted as light houses in the use of florescence and helped in the formation of thin layers (bio-films) on various surfaces in bacteria. Once we understand the way D-amino acids help in communication between bacteria, it will be possible to use them as a drug. It’s possible they can be used to disintegrate bacteria that forms on teeth, in the lungs of cystic fibrosis patients, on clogs in fuel lines and water tanks, and in medical devices such as catheters.

D-amino acid containing peptides found in lobsters help maintain salinity levels and facilitate courtship in mating seasons. In recent years, D-amino acid containing antimicrobial peptides were discovered (bombinines) in the secretion glands of fire-bellied toad skins (Bombina sp). In this peptide, the second amino acid was in the D-form (D-allo-isoleucine). Two different peptides were found containing D-amino acids in the second position of the amino acid sequence of the poison secreted by Platypus males.

One of the reasons for D-amino acids to exist in animal poisons is that peptides containing D-Amino acids can not be easily degraded by the proteases (peptide bond breaking enzyme) of the host or opponents. Even though proteases can quickly and easily digest proteins composed of L-form amino acids, they struggle to do so with peptide bonds between D and L form amino acids. Pharmaceutical companies are trying to add D-amino acids to the peptide-structured drugs to prevent the quick degradation of peptides and proteins used for treatments when ingested. However, the addition of a D-form amino acid brings the high possibility of a situation that changes the function of a peptide or protein, or causes the loss of a protein. Nonetheless, specialists in this field point out that at least some amount of the D-amino acids that are produced by trillions of bacteria found on the skin, in the digestive track, and among other parts of the body can still be utilized for human health and convenience.

The D-serine of the mammalian nerve systems (glial cells and neurons), the D-aspartate of the neuro-endcorine, endocrine tissues, and testicles, and the D-alanine and D-aspartate amino acids of aquatic animals are abundant. D-Serine in the brain is synthesized by the conversion of L-serine into D-serine by the serine racemase enzyme. D-aspartate is in charge of hormone synthesis and secretion, and the regulation of spermatogenesis, and is produced by aspartate racemase and degraded by D-aspartate oxidase. It is also predicted to play role in the synthesis of hormones such as melatonin and testosterone.

As of now, four enzymes have been detected to be in charge of D-amino acid metabolism in mammals. How these are controlled is still unknown.

Publications pertaining to the association of epilepsy, schizophrenia, and bipolar disorders with enzymes in charge of D-amino acid synthesis and break down have increased in recent years. From this point of view, serine racemase and D-amino oxidase can be used to develop new potential drugs regarding the treatment of similar NMDA receptor associated diseases.

The first data demonstrating the use of D-amino acids in saliva in organs outside of the human brain was obtained by Y. Nagata and his team at the University of Nihon, Tokyo. A team led by Kenji Hamase of the Kyushu University discovered high levels of D-alanine storage in the beta cells of the rat pancreas. Kuchel, who discovered the enzymes converting the L-amino acids in to D forms in duck-billed Platypus poison, also found similar enzymes in the hearts of mice and humans. According to Kuchel, the physiological roles of those in humans remain to be unknown.

As a result, the common feature of toxins and antimicrobial peptides that are produced and secreted by animals is to contain D-amino acid. These peptides can be the source of a potential drug in the treatment of diseases such as cystic fibrosis, schizophrenia, and macular degeneration of the eye.

These prove that, especially in biology, exceptions are common; life is enriched via examples of extraordinary lives, processes, and mechanisms in unexpected places by unpredictable molecules or interesting reactions that can’t be predicted. Such discoveries help deepen our wonder at the intricacy and wisdom of creation.

Astronomers have discovered a planet with the longest known orbital period. Exoplanet Kepler-421b has been identified through the Kepler observatory, a space-based telescope. It circles its star once every 704 days. More than 1800 exoplanets have been discovered so far, but compared to Kepler-421b, those had much shorter orbital periods, like a few weeks or even a few days. The host star for Kepler-421b is much like the sun, but it is little bit smaller and relatively cooler. With an orbital distance of 177 million kilometers, Kepler-421b gets about one-fourth the light from the host star as the Earth receives from the sun, which makes the exoplanet as cold as -100 °C. The unusual orbit places Kepler-421b beyond the “snow line,” which is accepted as the dividing line between rocky and gaseous planets. Outside of the snow line, water condenses into ice grains that stick together to build planets known as “gas giants.” Since gas giant planets are very close to their stars, theorists believe that many exoplanets migrate inward early in their history. However, Kepler-421b is the first example of why such migration may not be necessary.

Sunflowers’ internal clock

Plants are known to grow toward the sun to maximize the amount of energy they absorb. Sunflowers (Helianthus annuus) show the most fascinating behavior during summer, when they follow the sun as it rises in the east every morning and sets in the west every evening. In a recent study, scientists challenged the obvious explanation for this plant’s behavior: are flowers solely responding to sunlight or are there other unknown mechanisms at work? They designed a clever yet simple experiment where they grew sunflowers in chambers with a fixed overhead light that was continuously on. Surprisingly, for several days, the sunflowers under constant light kept moving as if the sun were rising in the east and setting in the west. This unexpected result suggests that sunflowers were not responding only to the direction of the light but also to an internal biological clock. Furthermore, they discovered that sunflowers bend when one side of the stem grows faster than the other. For example, the west side of the stem seems to grow faster to bend the plant towards the east in the morning. Scientists now hope to understand how an internal biological clock in sunflowers has the opposite effects on opposite sides of the stem. Sunflowers are not the only plants performing this diurnal dance; other agriculturally important crops such as soybeans and cotton exhibit the very same behavior. Solar tracking is known to boost plant yield and discovering the mechanisms of how plants track the sunlight might have important implications for improving global agricultural yields.

Friends linked by genes

It is a common observation that close friends look alike. Even centuries ago, Plato noted the tendency that good friends usually have similar appearances. Recently, a group of geneticists took this idea even further and suggest that people on average tend to choose friends who are genetically similar. The study provided convincing evidence that we have more DNA sequences in common with the people we pick as friends than we do with strangers in the same population. Researchers performed a genome-wide analysis of approximately 1.5 million markers of gene variations from 1,932 subjects of the Framingham Heart Study, which is one of the most comprehensive genetic databases. They identified 1300 pairs of non-relative friends and compared their genetic information to each other. The analyses showed that friends share similar genetic variations (around 1% genomewide), to the degree that it is as if they have the same great-great-great-grandparent – in other words, as if they were fourth cousins. Notably, friend pairs seem to have the greatest similarity in the genes that are responsible for a sense of smell and they show the most difference in immunity-related genes. Friendship entails spending a lot of time together and looking out for each other. Odors are strong behavioral cues in human psychology and people with similar olfactory preferences might like to prefer living or hanging out in similar environments. Likewise, it is potentially a big advantage that friends don’t get infected from the same microbes at the same times, so that one of them can take care of the other. As much as these anthropological implications are merely speculations with many caveats – and despite there being many obvious social, ethnical, and cultural factors that help determine friendships – the genetic basis of friendship and other social interactions may hold answers to at least some of the mysteries of human behavior.

Finkelstein S.L et al., Nature, October 2013

Astronomers have recently spotted a faint ray of light using the Hubble Space Telescope, a ten-meter telescope at Keck Observatory, located at the summit of Mauna Kea, a dormant volcano in Hawaii. Analysis of light showed that it was a galaxy formed 13.1 billion years ago, which is only 700 million years after the Big Bang, when our universe came into existence. This is so far back in time, it would be about 8 billion years before our sun was born. The new galaxy is called z8_GND_5296, and it is the oldest and most distant galaxy ever discovered. Because the universe is expanding, the lights coming from distant objects would be stretched, and their wavelengths changed, as they travel through the expanding universe. This phenomenon is called Redshift. It makes visible light look redder, and redshift increases proportionally with the distance to an object. Lights coming from z8_GND_5296 looked more redshifted than anyone had seen before. More detailed analyses showed that the mass of gz8_GND_5296’s stars was equivalent to 1 billion suns, which is approximately 50 times less than the Milky Way’s stellar mass. Even more surprisingly, the new galaxy is found to have an unusually high star-formation rate. This rate is typically calculated by how much raw hydrogen the galaxy yearly converts into new stars. gz8_GND_5296 converts hydrogen 300 times the mass of our sun, while the Milky Way produces 1 or 2 solar masses per year. One of the explanations for this extraordinary star-formation rate is that the early galaxies contained or drew in much more gas than scientists expected. The search for distant galaxies aims to find the very first galaxies formed after the Big Bang, perhaps the ones that produced the first natural elements. To this end, NASA plans to launch the James Webb Space Telescope (JWST) in 2018. JWST will reside in an orbit 1.5 million km from the earth and hopefully it will help astronomers to look further and further back into the origins of the Milky Way, and ultimately, the history of our universe.

Vast Freshwater Reserves Found Under Ocean

Offshore fresh groundwater reserves as a global phenomenon.
Post V.E.A et al., Nature, December 2013

As earth’s population rises, we face a serious problem of fresh water supplies. The United Nations predicts that half of the world will be struggling to find clean, fresh sources of water by 2030. Luckily, Australian scientists discovered huge freshwater reserves, and in the most unexpected place: under the ocean floor. Newly discovered reserves are estimated to contain 500,000 cubic kilometers of low-salinity water, located off the coast of South Africa, North America, Australia, and China. This vast reserve is approximately 100 times greater than the volume of the fresh water used since the beginning of the 1900s. This water reserve is thought to develop earlier in Earth’s history, perhaps over thousands of years, when oceans were not that deep and when the coastline was further out. Scientists hypothesize that rainwater leaked through the ground and had created these fresh water aquifers beneath layers of porous rock and/or soil. Around 20,000 years ago, the polar ice caps began to melt and these regions were covered by ocean. Fortunately, layers of either clay or sediment seemed to protect the reservoirs from salty contamination: the salinity of this water is low enough to be readily transformed into drinkable water. These water reserves can be extracted by constructing drilling platforms, either at sea or from the mainland, close to aquifers. However, drilling projects are usually very controversial due to environmental and economic costs. Scientists are currently seeking alternative, more environment-friendly ways to use these reserves. Nonetheless, mankind may have found a new vital water resource for the future.

Crows Don’t Forget a Face; Crow Intelligence Decoded

Abstract rule neurons in the endbrain support intelligent behavior in corvid songbirds.
Veit L. and Nieder A., Nature Communications November 2013

Scientists have long suspected that members of the corvids – a family of birds that includes ravens, crows and magpies – are extraordinarily intelligent. They make and use tools, remember multiple feeding locations, and exhibit highly social behaviors. Last year, scientists even demonstrated that crows captured in Seattle would never forget the face of their abductor and they would still taunt and dive-bomb the threatening face several years after the incident. To understand the mechanism of crows’ amazing face recognition process, neurobiologists designed an experiment, in which they trained the crows to perform memory tests on a computer. The crows were first shown an image and shortly afterwards, they had to select one of two test images on a touchscreen, using their beaks, based on switching behavioral rules. One of the test images was identical to the first image; the other one was a different image. Sometimes, the rule of the game was to select the very same image, and sometimes it was to select a different one. Remarkably, the crows were able to carry out both tasks and to switch between them almost perfectly. These tasks require a high level of concentration and mental flexibility that few animal species can manage – they even require a great effort for humans. By recording single-unit neuronal activity from an association area of the crow’s brain, known as the nidopallium caudolaterale (NCL), the researchers were often able to guess which rule the crow was following, even before the crow made its choice. The cerebral cortex in human brain is very large and it is thought to be home to complex cognitive functions including face recognition. However, since a bird’s cerebral cortex is much smaller than humans, people long thought that birds could not perform intelligent tasks. This study shows that birds use a unique non-cortical brain region, nidopallium caudolaterale (NCL), to sort sensory information and decide how to react.

A planet that revolves around another star outside our solar system is called an Exoplanet or Extra solar planet. Ongoing studies involving this field are carried out via simultaneous ground and space based missions and observations. Scientists are searching a small portion of the Milky Way galaxy, approximately 3000 light years away, by using ground and space telescopes, along with various other astronomic methods (1). Despite all this technology, the observation area is too big when compared to the size of the object of interest.

It has been calculated that the Milky Way, a disc shaped galaxy, consists of 200 billion stars spread over a diameter of nearly 100,000 light years and a thickness of 1000 light years. When we consider the amount of stars in a single galaxy, and the fact that there are between a hundred billion and one trillion galaxies in the universe, the number of possible exoplanets is likely much larger than those we currently know of.

Classification of exoplanets

Exoplanets are classified according to their physical, chemical, and other characteristics, along with their diameter and mass: Jupiter like; greater than Jupiter; Earth like; greater than Earth

Classifications according to surface and atmospheric temperatures are as follows: Hotter than Jupiter; colder than Neptune; colder than Jupiter; small blue dots or twin Earths.

The presences of free-floating planets which have lost their parent stars because of different formation processes or other factors have also been discovered.

One of the common features of the exoplanets currently discovered is their short distance to the star they revolve around, which is usually less than half the distance between the Earth and the Sun. The known exoplanets are also defined by their faster revolutions in much shorter periods. Therefore, larger planets that are closer to their stars can be observed easily. When these planets are passing in front of their stars, a decrease in the brightness of the star is detected via spectrometers (Figure 1).

Figure 1. Passing of a planet in front of a star and a spectrum of this event.

Radial velocity, one of the methods used to discover exoplanets, relies on the observations of a star’s kinetic fluctuations. The proximity and size of a revolving planet leads to slight changes in location and velocity of a host star. As a result of this, the star gets closer to earth and then becomes more distant, which is observed as the Doppler shift of spectral line color waves. 75 % of all known planets have been discovered using this method (Figure 2).

Figure 2. Doppler shift – radial velocity

Earth-like planets or habitable places

In an official NASA report in December 2011, the discovery of an Earth-like planet was announced for the first time. This planet, named Kepler 22b, is 600 light years away and remains the most similar one to Earth among the known heavenly bodies. The distance of Kepler 22b to its star shows a high possibility for the presence of a habitable zone.

So what does this mean?

Earth is such a special home for us humans that everything here has been assigned to serve us with delicate calculations. Factors such as the Earth’s mass, gravity, distance to the Sun, rotational and revolution velocity, chemistry, thickness of the atmosphere, magnetic shield, hydrosphere/land ratio, ecological balances, and average temperature are all perfect for biological life.

Earth revolves in such a region and position that a majority of the planetary water is in a liquid state and is not ice or vapor.Thedistance of the habitable zone to our Sun is between 135,000,000 – 225,000,000 km. Earth revolves at a 150,000,000 km distance to the Sun. The value of a habitable zone for each planet depends on the diameter, mass, heat and radiation strength of the host star. In other words, aside from the similarity of an exoplanet to Earth, a classification of its host star with in terms of size and age is also important.

Kepler 22b owns the title as the first planet to match the criteria above with its following features:

• Has a radius 2.4 times bigger than Earth
• Revolution time is 290 days (365 for Earth)
• 15% closer to its star compared to the Earth-Sun distance
• The size and surface temperature of Kepler 22b’s host star is very similar to that of the Sun’s
• The surface temperature of the planet is 22 C
• The size of the habitable zone for Kepler 22bis 133,500,000 – 240,000,000 km (Figure 3).

Figure 3. Comparison of the solar systems of Kepler 22b and Earth.

Aside from these similarities, it is noteworthy to report the problems that scientists encountered regarding Kepler 22b:

• The unknown presence of water on the surface
• No information on the gaseous contents of the atmosphere.
• The gravitational force is 2.5 times greater than on Earth.
• Rocks constitute the surface instead of soil.

The hardest part is that Kepler 22bremains 600 light years away from us. This means it would take us 11 billions years to get there with today’s fastest spacecrafts. Who knows when we will be able to decrease this time with the advent of superior technology.

What do religious scholar say about life in outer space?

Among His manifest signs is the creation of the heavens and the earth, and that He has dispersed in both of them living creatures. And He has full power to gather them together when He wills. (Ash-Shura 42:29)

While interpreting the Qur’anic verse above, Fethullah Gülen notes the following:

“Since the earliest times, this verse has been taken as a proof for the view that there are living creatures, whether resembling human beings or not, in the places other than the earth. This view may be true. The second part of the verse, ‘He has full power to gather them together when He wills,’ has been understood that these creatures and human beings will possibly come together either in this world or in that of the other creatures. … there may be earth-like globes in the heaven where creatures resembling earthly ones live.” (Gülen 2012, 272-273)

“Perhaps people will not be able to reach those places individually or as a whole generation, but this can be achieved by mankind as a species. In other words, when the Divine Will manifests itself in that direction, humans here can encounter those other life forms.” (Gülen 2007, 232)

This commentary reflects what Bediuzzaman Said Nursi had said decades ago:

“The earth, although much smaller than other heavenly bodies, is so densely inhabited by living creatures that even its grossest and most rotten parts are full of living things, such as micro-organisms. This shows that those infinite firmaments, with their numerous stars and constellations, are inhabited by conscious, living beings …” (Nursi 2010, 530-531) 29th Word, First Aim, First Fundamental)

Will there be wars over elements like there have been over petroleum and water? What element have we been using in color televisions? What substance is used to make energy saving, environmental light bulbs?

Each of the elements found in the periodic table have their own characteristics. After they have been cooked in the pot of the universe, these substances that are offered to our service can be radioactive (like uranium), metallic (like magnesium) and even gaseous (like helium). Seventeen of the elements not easily found among the layers underground have unique properties. These elements are called rare-earth elements, because it is hard to discover and mine them.

Rare-earth elements are in many of our everyday devices. The data projected on a computer screen is transmitted via optic cables containing erbium. The light of a tablet device is generated by the phosphorescent element europium. We actually touch indium covered surfaces when we scroll our fingers on touch screen monitors. When listening through headphones, we are using neodymium magnets that are ten times stronger than iron magnets.

From space technologies to defense industries, from cell phones to LED lighting, many such rare-earth elements are used in every stage of our lives. These elements – many of which we cannot live without, even though we’ve never heard of them – were recorded into the Critical Materials Strategy Document published by the U.S. Department of Energy in 2010. In a public announcement, the department declared fourteen of the elements as specially significant regarding clean energy, listed six of them as critical, and the other four as near critical. Fifteen elements, beginning with lanthanum and ending with lutetium, numbered between 57 and 71, comprise lanthanides. Combined with scandium and yttrium, these make up the seventeen rare-earth elements.

The elements that we touch on screens

Indium (atomic number 49) gains the properties of electrical conductivity and optic transparency when combined with tin, which, at number 50, is indiums’s neighbor on the periodic table. Optical transparency is a desired property for plasma screen and television technologies. Indium is also an important material for mobile phone touchscreens. Interestingly, when indium combines with cadmium, also as a neighbor at number 48, it loses the optical transparency. Instead, it is able to absorb light. Light harvesting is a very critical feature in the production of solar cells.

The relationship of indium with its two neighbors opens new horizons for scientists. In the near future, it is hoped that many unknown and interesting features will be unearthed by investigating the known elements of the periodic table. It is amazing that these elements have been around for thousands of years in the universe only to be discovered by technological advancements.

The need for rare-elements in the world is around fifty thousand tons. The current recorded reserve for rare-earth elements is 110 Million tons. Currently, 95% of the demand for rare-earth elements is supplied by China, yet the country only has 35% of the world’s reserves. Therefore scientists are constantly searching for rare-earth element mines to eliminate the Chinese monopoly and to boost the production of these rare materials. In recent years, China has gotten into political debates with Japan and the United States by curbing rare-earth element exports. Economic journals covering these debates wondered if “element wars” were near. In 2010, a massive reserve of elements, enough to sustain worldwide demand, was discovered in the Pacific Ocean. Developed countries are now planning to recycle rare-earth elements from used devices due to low reserves.

Yttrium, europium, and terbium (atomic numbers 39, 63 and 65) have been known for a long time. Terbium and yttrium are named after the Swedish town of Ytterby. Yttrium is the first rare-earth element discovered, at the end of 18th century. Plastics containing europium are used to make laser products; it’s also used as an element to provide the red color on television screens. Yttrium has a supplementary role that enhances europium’s red color production. And terbium oxide activates the green phosphorescence of television tubes with its yellow-green phosphorescent property.

Terbium also enables an 80% reduction of energy consumption in light bulbs. This makes it one of the most wanted elements in the $2 billion rare-earth element market. Today, when we purchase class A type light bulbs, we are actually buying rare elements like terbium.

Neodymium (number 60), which emits a green light via laser pointers, is also used in the magnets of electric motors. When neodymium combines with boron and iron, it makes a magnet twelve times stronger than simple iron magnets. Because it is significantly less dense than iron, it makes electric motors and laptop computers much lighter. Another interesting feature of neodymium is that it enhances the data storage capacity of hard drives. Furthermore, neodymium is wanted for electrical devices and wind turbines.

The union of elements

Dysprosium was discovered in 1886 and can never be found in a free form in nature. This is because it exists in a compound form with other minerals, like gadolinite. Dysprosium is also known for its magnetic property, and when mixed with terbium and iron, it forms a substance called Terfenol-D. In a magnetic field, Terfenol-D has unique transformational abilities. Dysprosium is utilized in laser production together with vanadium, and it emits infrared radiation when used with cadmium.

The magnetic alloys of iron, boron, and neodymium lose their magnetic features beyond 300 degrees Celsius. However when this alloy is combined with dysprosium at a 5% ratio, that problem disappears. Therefore, these magnets are used for electric turbines and hard disc motors. Dysprosium also makes magnets in electric motors 95% lighter. And dysprosium and nickel mixed fillings are used as cooling rods in nuclear reactors.

The human mind becomes fascinated after seeing all the wisdom and properties involved in these lifeless elements. Either we conclude that these elements have doctorate degrees in physics and chemistry from Harvard University, or we may express our weakness and fascination in front of The Grand Creator who created and presented these elements for our benefit.

Is the yellow color in glasses from the planet Ceres?

Since Dell recalled four million laptop computers in 2006, because of a possible explosion caused by overheating battery, scientists’ eyes have been focused on lanthanum and cerium. These two elements are considered to be safer than other alternatives. Lanthanum and cerium are used in electrical equipment and energy saving light bulbs, and are classified as critical elements in these processes, along with tellurium. Cerium, named after the planet Ceres, is responsible for the yellow coloration in glasses. Cerium is also used in polishes, ceramics, and petrol refineries. Tellurium is produced indirectly, unlike most other elements. The production of cadmium takes place during zinc production, and tellurium during copper refining. Tellurium is a cheaper element that has been used in combination with cadmium on solar cells since 2009; before then, most solar cells used expensive silicon panels.

Elements in our lives, from space rockets to ultrasound imaging

Hafnium, tantalum, erbium, and technetium are important elements, even though they are not listed critical. Even though hafnium and technetium are not rare-earth elements, they were still added to the critical material strategy document produced by the US Department of Energy. Hafnium is employed in space rockets for its resistance against extreme temperatures and wearing. Hafnium oxide is a valuable material for electronic transistors since it is a very effective electric insulator. It is 20% faster than the silicon oxide that is commonly used in transistors. A transistors length is around 65 nanometers when silicon oxide is used, but it is only 32 nanometers with transistors made of hafnium oxide. This 50% decrease enables smaller devices.

Touchscreens containing indium, laptop computers powered by lithium ion batteries, and cell phones with hafnium transistors are some of today’s technological wonders. Would these inventions still be possible without these elements? Could we reach the high capacities in hard discs without the tantalum? Would we be able to protect ourselves from electric leakage in computers without high quality electric insulators such as tantalum oxide?

Radioactive technetium, which was discovered in 1937, is the first artificially produced element. The technetium 99 isotope is used in nuclear medicine. Technetium produced from uranium has a half life of 211,000 years, as opposed to the 6 hour half life of the technetium 99 isotope. The number of technetium based nuclear medicinal tests, like ultrasounds and x-ray imaging, is estimated to be above thirty million annually.

We take advantage of these elements in every stage of our lives, from medicine to technology. Could we become dependent upon elements the way we are upon petroleum? Only time will tell. Either these elements will be replaced by other materials, or other technologies will outdate the current technologies. It is also possible new elements will be discovered.

A majority of our modern technologies would not exist without these elements that were dispersed among the earth billions of years ago. These elements were placed here for our benefit, and so we could utilize them, and produce institutes of scientific research and education to study them.

Jacobs J. et al. Direct recordings of grid-like neuronal activity in human spatial navigation. Nature Neuroscience, 2013

Do you happen to have a poor sense of direction? Do you often find yourself holding a map upside-down? Well, now you can blame your grid cells. Using direct human brain recordings, researchers have identified a novel type of cell in the brain that helps people keep track of their relative location while navigating through an unfamiliar environment. Scientists got this rare opportunity to identify these unique cells while they studied brain recordings of epilepsy patients via electrodes implanted deep inside their brains. These cells have been called “grid cells” because they are activated in a triangular grid pattern. The “grid cell” is distinct among brain cells because its activation represents multiple spatial locations, which allows the brain to keep track of navigational cues, such as how far you are from a starting point or your last turn. This type of navigation is called path integration. During brain recordings, 14 study participants were asked to play a video game where they ride a virtual bicycle to navigate from one point to another to retrieve objects and then recall how to get back to the places where they found the objects. While participants were playing the game, researchers examined the relation between navigation and the corresponding activity of individual neurons. Results were striking: each grid cell responded at multiple spatial locations that were arranged in the shape of a grid suggesting that the navigation information is principally encoded in our brains through this triangular grid pattern. Without grid cells, humans would frequently get lost or have to navigate based solely on landmarks. Differences in how well the grid cells work could potentially explain why some people have a better sense of direction than others. In addition, grid cells are located in the entorhinal cortex which is a critical component of human memory. The entorhinal cortex is also the first brain region affected in Alzheimer’s disease. Thus, understanding how grid cells work could potentially help us to understand why people with Alzheimer’s frequently become disoriented as well as to develop new strategies to improve brain function in the affected individuals.

Giant viruses open Pandora’s box

Philippe N. et al. Pandoraviruses: amoeba viruses with genomes up to 2.5 Mb reaching that of parasitic eukaryotes. Science, 2013 Jul 19

On a fairly ordinary day, two French biologists were analyzing water samples collected off the coast of Chile. What they saw under the microscope was quite amazing: a previously unidentified organism, about the size of a bacterial cell, appeared as a large dark spot. Astonishingly, these new organisms seemed to be infecting and killing the amoeba in the water. Later, another group of researchers found a similar organism in a pond in Australia. Both groups soon realized that they discovered a type of “giant” virus which is at least twice as big as the largest known viruses. The biggest virus discovered so far was called Mimiviruses, with a size of 700 nanometers and carrying more than 1000 genes. The newly discovered viruses are called Pandoraviruses, which are 1 micrometer long and 0.5 micrometers across. Pandoraviruses are visible under a light microscope and contain more than 2500 genes. A viral genome consisting of 2500 genes is extremely large compared to known viruses, such as the Influenza or HIV, which only contain 10 genes or less. More importantly, 93% of the genes did not resemble any known lineage in the natural world, suggesting Pandoraviruses are not related to any known virus family and may represent a new life form. These findings generated new perspectives about how scientists see viruses. It raised the possibility that there might be many different kinds of giant viruses out there to be discovered. Some biological features in these giant viruses could easily blur the line between life forms and viruses, which are considered to be non-living. Although Pandoraviruses do not infect human cells, there might be other giant viruses out there that could infect human cells. There are still a lot of human diseases known to have an infectious component but for which no infectious agent has been identified yet. This study will definitely encourage people to actively look for the role of giant viruses in some diseases.

See through the Ears

Haigh A. et al. How well do you see what you hear? The acuity of visual-to-auditory sensory substitution. Frontiers in Psychology, 2013 Jun 18

Scientists have created a revolutionary device for the blind that allows them see the world through their ears. The device “vOICe” trains the brain to invoke mental images of what they are hearing around them. The first test trial of vOICe has been performed on blindfolded sighted people. The participants took a standard eye test where they were asked to view the letter E turned in four directions and in various sizes. The best visual acuity is considered 20/20 (distance in feet/size of the E) and the majority of participants were able to achieve the best performance possible, nearly 20/400 sight. This is an impressive result when compared to an alternative stem-cell based sight restoration technique, which only yielded 20/800 visual acuity. In addition, the affordable and non-invasive nature of vOICe would offer a unique option. But, how might this work in practice? One can imagine that visually-impaired people would wear a discreet head-mounted camera such as Google Glass and receive wireless audio information through mini earbuds. As the person turns to look in various directions, the device scans images and correlates those with soundscapes, then the person’s brain would momentarily translate those into mental images of the objects — like braille for the ears. These sensory substitution devices could potentially be employed in combination with other alternative invasive techniques to train the brain to see again, or even to see for the first time.

Once the heart has found You,

Would it ever remember another?

Once it has burned in Your fire,

Would it ever burn in another?

Only those who have found You

Are purified in an incessant flow;

Satisfied with Your love,

Would they ever be content with another?

You gave being to the universe,

All life emanates from You.

Having found Your ocean,

Would they ever dive into another?

Your Name is recited everywhere;

It is the cure for the ailments of the soul.

Once having truly believed in You,

Would they ever assume their Lord to be another?

Absorbed in awe at Your beauty,

On the path of love,

Once having tasted the honey from Your comb,

Would they ever taste another?

Once having discovered You,

Hastening towards and meeting You,

Having entered Your sanctuary,

Would they ever seek another?

Did the Companions of the Prophet go to America?

Research conducted in the West during the twentieth century has proven the existence of Muslims on the American mainland approximately seven centuries before Christopher Columbus. Similarly, archeological excavations, linguistic, and philological analyses of languages and settlement names in the region, the fact that coins, household tools and other utensils were discovered there that were similar to those of the Abbasids in the eighth and ninth centuries are all justifications of the theory that Muslims, beginning from 650 CE, made their way to the continent for settlement, during which time they erected mosques and schools, leaving a prolonged impact on the natives, i.e. American Indians.

The Islamic sources carry no information as regards Muslim settlement in America, although research undertaken by Professor Barry Fell of Harvard University confirms that Muslims reached the continent at the time of Uthman, the third Caliph, concomitantly indicating the significant possibility that some of the Companions could have arrived there as well.

Many Western researchers acknowledge the famous map of Piri Reis as proof of Muslim presence in America long before the endeavors of Columbus, as it minutely comprises the map of America, as well as extremely accurate measurements of the distance between America and Africa.

According to Salvatore Michael Trento, former director of the Center for Archeological Research in Middletown, New York, before embarking on his first voyage to America, Columbus had read the book of Roger Bacon of Oxford University, which comprised information, compiled from a variety of Arabic resources, about geographical regions on the other side of the Atlantic; hence Columbus’ previous knowledge of the islands in the Atlantic Ocean and other places.1

Proofs in Western sources

1. Professor Barry Fell, retired lecturer from Harvard University and also a member of the American Academy of Science and Arts, the Royal Society, the Epigraphy Society and the Society of Scientific and Archeological Discoveries, is adamant about the arrival of Islam in America in the 650s,2 predicating this argument upon the Cufic calligraphy belonging to that era found in various diggings across America. If the words of Professor Fell have truth-value, then the Muslims had arrived in America during the era of Uthman, or at least that of Ali, the fourth caliph. Such information, however, is not found in Muslim sources.

Professor Fell again uses the results of various archeological diggings undertaken across many regions in the states of Colorado, New Mexico, and Indiana to assert the construction of Muslim schools during 700-800 CE. Writings, drawings, and charts inscribed on rocks discovered in the most remote and untainted terrains of Western America are relics bestowed by the elementary and intermediate systems of Muslim education at the time. These documents were written in the old Cufic letters of North African Arabic, covering subjects such as reading, writing, arithmetic, religion, history, geography, mathematics, astronomy, and navigation. The descendants of these settlers are thought to be the current native tribes of Iroquois, Algonquin, Anasazi, Hohokam, and Olmec.

2. The second evidence offered by Professor Fell is that the inscription of “In the Name of God” (picture 1), found on a rock during archeological work in Nevada, belongs to the seventh century, when the haraka sign system had not yet been developed. Likewise, the stone bearing the inscription “Muhammad is the Prophet of God” (picture 2) is pertinent to the same era. As seen by comparison of the two pictures, the inscriptions are not in the style of Modern Arabic; conversely they are in a Cufic style relevant to the seventh century.3

The Arabs, according to the findings of Professor Fell, settled in Nevada during the seventh and eighth centuries. The earlier existence of a school, which taught Islam and science, particularly navigation, has come to light following the archeological investigation undertaken by Professors Heizer and Baumhoff of California University around site WA 25 in Nevada. The excavations in Nevada have uncovered writings in Naskhi Arabic and Cufic style that are inscribed on rocks which carry information about this school (picture 3). The application of the mathematical formula “five diamonds equal an alif” (alif is the first letter of Arabic alphabet) may be seen in this picture (pictures 3b and 3c). The Arabic letters in pictures 3b and 3c, found amid excavations in Nevada, are in exactly the same style as North African Arabic. Again similarly, another rock was found in Nevada bearing the name “God”, the style of which is yet again reminiscent of the prevalent technique of seventh and eighth-century North Africa. The calligraphical similarities between various writing styles of the Prophet’s name over diverse periods, particularly those relating to Africa and America, found during archeological investigations are striking indeed. Figure A of picture 4 was found in al-Ain Lahag, Morocco and figure B in East Walker River; both are currently at the University of California. Figure C was discovered in Nevada and figures C and D were located in Churchill County and are also currently preserved at the University of California; likewise figure F was discovered in al-Haji Minoun, Morocco, while figure G, inscribed on ceramic, was revealed in al-Suk, Tripoli, Libya and figure H, at the University of California, was discovered at Cottonwood Canyon, while finally figure I was located on the border of Morocco and Libya. All these inscriptions belong to the eighth and ninth centuries, clearly illustrating the resemblance in style between North America and North Africa, as well as overtly suggesting a migration that occurred from Africa to America.

3. In the twelfth century the Athapcan Tribe, comprised of native Apaches and Navajos, raided the area inhabited by the Arabs, who either ended up fleeing or were exiled toward the South. These illiterate natives were spellbound by the schools founded by the Arabs, and, perhaps with the assistance of captives, attempted to imitate the same subjects, transforming the geometrical shapes into mythical beasts, which carried on for centuries.

4. Picture 5 is the Cufic writing found in 1951 in the White Mountains, close to the town of Benton on the border of Nevada. The words Shaytan maha mayan, i.e. the Devil is the source of all lies, have been written in a Cufic style peculiar to the seventh century.

5. Once more, a rock inscription belonging to post-650 CE, bearing the Cufic letters H-M-I-D of the word Hamid (picture 6), is another Arabic script discovered on the Atlata rocks in the Valley of Fire in Nevada.

6. While traveling from Malden to Cambridge in the state of Massachusetts in 1787 (on what is now RT. 16), the Reverend Thaddeus Mason Harris noticed some coins discovered by workers during road construction. The workers, not putting much value on these coins, presented him with a handful. Consequently, Harris decided to send these coins to the library of Harvard College for examination (picture 7). The study yielded that these were in fact Samarqand dirhams from the eighth and ninth centuries. As can be seen in the picture, the coins manifestly display the inscriptions La ilaha ill-Allah Muhammadun Rasulullah (There is no deity but God, and Muhammad is His Messenger) and Bismillah (in the name of God).

7. Picture 8 shows a piece of rock discovered in a cave in the region of Corinto in El Salvador, bearing the inscription Malaka Haji mi Malaya; this has been identified as belonging to the thirteenth century, suggesting a possible arrival of Muslims in South America, perhaps coming from somewhere near Indonesia.

7. During his second voyage, Columbus was told by the natives of Espanola (Haiti) of black men who had appeared on the island before him and they showed him the lances that had been left there by these Africans to support their assertions. The tips of the lances were of a metal, an alloy of gold, which they called guanin, a word which is semantically remarkably similar to the Arabic word ghina, meaning richness. Columbus had in fact brought some of this guanin back to Spain, recording that it was composed of 56.25% gold, 18.75% silver and 25% copper, ratios that were prevalent in African Guinea as standards for the processing of metals.

8. On his third voyage to the New World, Columbus visited Trinidad, where the sailors noticed the symmetrically patterned cotton and colorful handkerchiefs of the natives. Afterward, Columbus realized that the handkerchiefs, which the natives called almayzar, were all much the same in color, style, and use as the headscarves and waist bands used in Guinea. The word almayzar is Arabic, and denotes a cover, tie, apron, or skirt, and is a component of the regional costumes of the Moors, Arabs and, Berbers of North Africa, who had conquered Spain in the eighth century. Columbus observed that the local women wore cotton garments and wrote in astonishment that they had learned of the concept namus, i.e. chastity. In much the same vein, Hernan Cortes, another Spanish explorer, later recorded that the clothing of local women consisted of long veils and skirts decorated with ornaments that were similar to those of the Moors. Ferdinand, Columbus’ son, was also quick to notice the resemblance between the cotton dresses of the natives and the ornamented shawls fashioned by Moorish women in Granada. The cradles used by the natives, furthermore, very closely resembled those of North Africa.

9. Columbus recorded on 21 October 1492 that he had noticed a mosque on top of a mountain while sailing around Cibara on the northeast coast of Cuba. Relics of mosques carrying Qur’anic inscriptions on their minarets have been found in Cuba, Mexico, Texas, and Nevada since these times.

10. Leo Weiner, a well-known Harvard historian and linguist, stated in his book The Discovery of Africa and America, written in 1920, that Columbus was aware of the existence of Mandinka, an ethnic group of West Africa, in the New World. The same book also affirms that Columbus was aware that West African Muslims were living across North America, including the south, middle regions and Canada, as well as in the Caribbean, and that they had marital and commercial ties with the native tribes of Iroque and Algonquin.

11. A preponderance of the voyages embarked upon by Columbus and other Spanish and Portuguese explorers toward the other side of the Atlantic were undertaken only in the light of the geographical and navigational knowledge prepared by Muslims. Al-Masudi’s (871-957 CE) work Muruj’uz-Zahab, for instance, was written with this sort of data compiled by Muslim traders from across Africa and Asia. Two of Columbus’ captains on the first voyage, in actual fact, were Muslims: Martin Alonso Pinzon was in charge of the Pinta, while his brother Vicente Yanez Pinzon was the designated captain of Nina; both were from the Moroccan Marinid dynasty, descendants of Sultan Abu Zayan Muhammad III (r. 1362-1366). Formerly well-to-do ship riggers, they assisted Columbus in organizing his voyage of exploration, preparing the Santa Maria, the flagship, and covering all its expenses.

12. Christopher Columbus has recorded the custom of nose piercing, which used to be and still popular in the Middle Eastern and Arab countries, as being prevalent in some islands across the Atlantic also mentions the writing of letters in Arabic.

13. In the account of sixteenth century missionaries in America, the local copper mines, found particularly in Virginia, Tennessee, and Wisconsin were not operated by the natives, but instead by people from the Middle East, towards whom the natives nurtured a profound sympathy.

14. A sum of 565 names, 484 in America and 81 in Canada, of villages, towns, cities, mountains, lakes, rivers and etcetera, are etymologically Arabic, designated by locals long before the arrival of Columbus. Many of these names are in fact the same as names of Islamic places; Mecca in Indiana, Medina in Idaho, Medina in New York, Medina and Hazen in North Dakota, Medina in Ohio, Medina in Tennessee, Medina in Texas, Medina and Arva in Ontario, Mahomet in Illinois and Mona in Utah, are just a few noticeable names at the outset. A closer analysis of the names of native tribes will immediately reveal their Arabic etymological ancestry; Anasazi, Apache, Arawak, Arikana, Chavin, Cherokee, Cree, Hohokam, Hupa, Hopi, Makkah, Mohician, Mohawk, Nazca, Zulu, and Zuni are only a few.

House and building Structures

Archeological excavations conducted throughout North America and North Africa reveal a corresponding architectural resemblance between ninth century buildings. The structure of a Berber house of the Atlas Mountains, Morocco (picture 9), for instance, is exactly the same as that of a house in New Mexico (picture 10). The same similarity can be traced between the Castle of Montezuma discovered in Arizona and the remnants found in Mesa Verde in Colorado and the general structure of Berber buildings (picture 11-12).

The research undertaken by Professor Cyrus Thomas of the Smithsonian Institute shows that a small cabin built from piles of rock found in Ellenville, New York is virtually the same as the cabin, again of rock, found around Aqabah, Southern Arabia, both of which are thought to have been built around the start of the eighth century (picture 13).

Arabic words prevalent among natives prior to the arrival of Europeans

The pervasiveness of many Islamic words across the continent prior to European influx is verified by the following terms discovered in the regions currently known as New England and Nova Scotia, in America and Canada respectively. Fell pointed to some words as example of Arabic influence on Native Americans. All of the words listed below are derived from the Arabic language. However, time had eroded their original meanings and most are not used in Arabic today.

The last Muslim stronghold in Spain, Granada, fell just before the Spanish Inquisition was established in 1492. Non-Christians were forced to either convert to Catholicism to save themselves from the tyranny of the Inquisition or were exiled from the country. Documents exist which prove the existence of immigrant Muslims in Spanish America before 1550. In 1539 an edict from Spanish King Charles V was put into practice which forbade the immigration of Muslims to settlements in the West. This edict was later expanded to expel all Muslims from overseas Spanish colonies in 1543. The existence of Muslims in overseas islands and regions was known along with the fact that the Spanish king issued such an edict. Again, in many Islamic sources, it is noted that Muslims living in Spain and North Africa made overseas voyages during the Andalusia period. Scientific research on this subject will bring out many documents into the daylight, documents which have escaped the notice of both Muslims in America and those throughout the world, which will perhaps serve, in the future if not immediately, as a starting point for a re-evaluation of the history of America.
