Laser Light in Biomaterials?

Rachel Berkowitz. “Peacock feathers can be lasers,” Science, July 2025.

With their impressive long tail feathers and eye-like markings, peacocks have a unique place in the animal kingdom. A recent study has revealed that these amazing birds have a secret: they can emit beams of laser light. According to this study published in Scientific Reports in July 2025, there are tiny reflective structures in these feathers which can amplify light into a laser beam.

Lasers form when the medium’s electrons emit photons and the light is further amplified into a coherent beam in a reflective cavity. Researchers say what they have found in peacock feathers is the “first example of a laser cavity” in the animal kingdom. Physicist Nathan Dawson from Florida Polytechnic University and his colleagues conducted their study on the ordered microstructures within the feathers which produce vivid colors as they reflect light at specific frequencies. Their goal was to see if these microstructures could also function as a laser cavity. To do that, they dyed and then energized the feathers with soft pulses of light.

What they found was not visible to the naked eye, but with lab instruments they detected beams of yellow-green laser light originating from the eye-like markings on the feathers at two distinct wavelengths. Surprisingly, the laser light emitted from differently colored parts of these markings appeared at the same wavelength. According to Dawson, the probability of this is “like rolling two 100-sided dice and always getting 74 from one die and 83 from the other.”

Further research that looks for laser light in biomaterials, according to Dawson, can have ramifications, for instance in medicine, and if put safely into the human body help us with biosensing, medical imaging, and therapeutics.

Reading Each Other’s Minds?

Daryl Austin. “Is ‘twin telepathy’ real? Here’s what scientists say.” National Geographic, August 2025

Twins, a 1988 comedy film, features Arnold Schwarzenegger (6’ 2”) and Danny DeVito (4’ 10”) as two unlikely fraternal twin brothers who were born as a result of a secret genetic experiment. Given their height and other apparent physical – and behavioral – differences, the unlikeliness is impossible to miss.

Many twins, however, especially monozygotic ones, are almost identical in physical appearance. These similarities have fueled myths suggesting a connection between twins that goes beyond shared DNA, physical traits, and mirrored behaviors. One such myth is whether twins can communicate through telepathy. Daryl Austin defines in National Geographic (August 2025) twin telepathy as “the belief that twins – especially identical (monozygotic) ones – can sense each other’s feelings, thoughts, or physical sensations across distance without using the five senses.”

Despite the murkiness in this matter among the scientific community, Austin notes that some recent studies have produced intriguing results. In one of four pairs in a 2013 study published in the Journal of Scientific Exploration, “the non-stimulated twin showed a response that was considered above chance.” In another research in 2024 which involved 91 stimulus trials, 18 stimulation epochs were identified – this is “nearly double the 11 hits expected by chance.” Still, none of these findings qualify as “credible scientific evidence that twin telepathy exists.” The real focus, then, should be on what twins genuinely share: growing up in the same environment, experiences, routines, cultural influences, and genetic traits. According to Joanne Broder, twins are “more likely just demonstrating a communication bond, not reading each other’s minds.”

Password-Protected Brain Implant Decodes Internal Speech

Gemma Conroy. “A mind-reading brain implant that comes with password protection.” Nature, August 2025.

A new study on a brain-computer interface (BCI), or mind-reading device, shows meaningful improvements in accurately decoding internal speech, while safeguarding privacy through a novel password mechanism. The device was tested on four individuals with speech impairments caused by stroke or motor neuron disease. Electrodes placed on the motor cortex recorded neural activity as participants either attempted to speak or silently imagined words and sentences.

The study revealed that both types of speech arise from the same brain region, though signals linked to internal speech are weaker. AI models were then trained to recognize phonemes—the smallest units of speech—from these signals and construct words and sentences from a vocabulary of 125,000 words. The system decoded up to 74% of silently imagined sentences with accuracy comparable to existing BCIs that rely on attempted speech. It also detected spontaneous self-talk, such as silent counting, suggesting the system can capture more natural forms of inner dialogue.

To prevent unintentional decoding of private thoughts, researchers introduced a password trigger to control when decoding begins. When participants imagined the phrase “Chitty-Chitty-Bang-Bang,” the system recognized it with over 98% accuracy, preventing the unintended translation of private thoughts. This is an important step toward helping people with paralysis or speech loss communicate naturally through thought. The password mechanism helps with privacy protection for real-world use. Researchers aim to explore other brain regions beyond the motor cortex and hopefully improve speed and accuracy to broaden the system’s usefulness for different types of speech impairments.

In this issue the article on “The Adaptation in the Senses” points to the fact that the human body is blessed with an ability to adapt to the surrounding conditions by way of which our senses get used to changing climate, light, and even pain. This feature of our body is a mercy, considering that if we could not adapt to circumstances, life would be torture. Could this be the reason bombings and civilian sufferings in Iraq do not irritate me-because I have been watching or reading about it for more than five years now and my senses are adapted to being exposed to the same play on the Iraqi stage?

While voicing a strong longing for the lofty and colorful life of centuries ago, the lead article is a consolation for the victims of all times as it reminds the reader of how joyous enthusiasm was once achieved: “We believed as long as we could employ our willpower up to its potential all problems could be overcome as a result of divine help. We always managed to discover contentment in our soul and proceeded on our course.” In such a state of psychology no misfortune can shake any individual or community.

In this issue you will meet Ottoman Women: Myth and Reality, a book which won the Benjamin Franklin best book in history award in May 2008. Its description of the legal rights and social status of Muslim women in the nineteenth century will shatter life-long prejudices about harem life. Another writer, Dr Salik, takes us on a space journey to discover planets orbiting other stars where scientists hope to test theories developed on planet creation. Thomas C. Smedley offers an interesting pattern of engaging with foreign cultures as a result of his personal experiences with the Turkish community in the USA. Smedley says that by practicing role reversal, a person of good will can overcome the barriers of language, religion, and nationality.

Ramadan mubarak! We wish this holy month of Islam may be a means of peace and joy for all peoples of the world.

Based on a sensible interpretation of the cosmos and events, we considered the arrival and departure of each existence in this world very normal, a process taking place in a gentle manner; this mysterious journey instilled in us profound spiritual expansion, for it was a means of reunion, each action and replacement was like being discharged of duty and freedom from the burdens of service at the end of which await the realms of divine favors hat is constantly heard, touched and smelt; we, as humans, don’t hear or feel certain things after a certain period of time. In medical terms, this process is called “adaptation to the senses.” If we have to go into a very stinky place, we intensely feel the smell at first, but after a while, we begin to feel it less. Another example can be given about those who wear glasses. They sometimes search for their glasses in different places thinking that they have lost them, even though they still wear them.

Our friend’s adaptation levelwas a little higher than the normal, but considering the disturbance of those who wear glasses would feel on their noses, it is better understood that this adaptation is a great favor of All-Powerful and All-Knowing God.

In the absence of adaptation

If we weren’t endowed with the capacity of adaptation, our brain would be busy with unnecessary information and we would be disturbed by the constant touching in our body. The cells that feel the senses are called “receptors.” There is an amazing adaptation in most parts of the cells that sense the touching in the skin. For instance, when we wear something, we feel the first touch of the garment to our body, but this feeling caused by the garment disappears afterwards. If we were to feel everything touching our skin, life would be very difficult for us. Likewise, in some patients, the adaptation to senses disappears and this makes the things harder for them. Some patients, on the other hand, develops hypersensitivity. They feel pain and suffering even by the slight touching of their garments. It is very hard to cure this illness which is called “neuropathic pain” in medicine. They feel cancer-like severe pain. Scientists are still working on the studies to stop this kind of pain.

How does adaptation occur?

Adaptation happens as a result of a different mechanism for each sense. Touching causes a liquid movement in the cytoplasm of the receptor cells. This movement is sensed by the cell and conveyed to the brain in the form of electric signals. Despite the continuation of touching, the cytoplasm movement in receptor cells is stopped after a while and no signal is sent to the brain. So, no touching is felt. But when touching stops, as a result of a liquid movement in the cytoplasm of the receptor cells, a new signal prompts the brain that “touching is over.” In short, only the beginning and the end of touching is communicated to the brain. Despite the continuation of touching between the beginning and the end, the brain (rather the “soul”) is not bothered by this redundant information. Even though, many types of receptors serve in the process of adaptation to touching, only six of them have been thoroughly studied and named. The adaptation is not the same in all receptors; fast and advanced in some of them, while in some of them it is slow and weak. For example in touching receptors of the skin (Merkel disks), the adaptation is relatively little and there is no adaptation at all in some senses such as feeling the pain. In some receptors (such as Ruffini’s corpuscles) located in dermis (bottom layer of the skin), deep organs and joint capsules, the adaptation is very little. These receptors send the weight and pressure signals required for the absence of adaptation. Weight and pressure receptors located in the joint capsule are responsible for sensing the angle degree of the joint. The brain receives information from them about the angle degree of the joints and it constantly uses it while sending orders of movement to the muscles of the skeleton. We can walk and do the other movements that require balance thanks to these perfect processes happening beyond our consciousness. If the brain didn’t know the information regarding the angle degree of the joints, some jobs that require delicate balance such as the job of construction workers wouldn’t be properly done.

Adaptation in various senses

Adaptation in seeing (accommodation): Adaptation in seeing is different from the one for touching. If we keep looking at an object, we keep seeing it. In this sense, there is no interruption in adaptation and seeing. This is another favor of God among many of His favors. If the adaptation in seeing were to be similar to the one in touching, we wouldn’t be able to do many activities that require walking, reading, sitting, standing and being in balance. All-Merciful God placed different adaptations in our eyes appropriate for the jobs that they do.

Adaptation in seeing near and far: We keep seeing an object no matter how nearer or farther we move it. Despite the change in the distance of the object, our vision doesn’t change. These processes are automatically carried out depending on the distance we look and they are operated under the framework of optical principles such as changing the shape of the eye lens and approaching of the lens to the retina or moving away from it.

Adaptation in seeing in the light and dark: Our eyes detect and adapt to the new surroundings, be it light or dark. During this adaptation process, seeing in the dark and light is made possible by adjusting the degree of vision and increasing and decreasing it one million times. The activities of the photoreceptors (in the shape of rod and cone) are carried out by an amazing knowledge and power.

Adaptation in smelling (olfaction): The smelling receptors of the nose adapt to the bad smell at a rate of 50 % in its first encounter. So, the dense bad smell felt in the first encounter disappears immediately. A minute after this encounter, the sensing of the bad smell is eliminated upon the orders coming from the brain to the nerves of smell. Garbage men or cleaners or the people working in slaughterhouse or sewerage do not get disturbed, as a favor of God, by the bad smell as much as other people do.

Adaptation in tasting: the adaptation happens one minute (at most) after the “tasting.” Yet All-Powerful and All-Knowing God created the adaptation capacity for the bitter materials very low, because most of these materials are a kind of poison for our body. Therefore when the babies unconsciously want to eat something poisonous, they take them out at once and are avoid of being poisoned.

Adaptation in temperature: The temperature receptors are intensely stimulated in sudden temperature changes. The adaptation occurs in 30 seconds or one minute as the intense of stimulation decrease. However there is no 100% adaptation, because the receptors sense both the sudden changes and constant situations. Remember, both extreme hot and cold are harmful for the body. The fact that the adaptation in this sense is limited is another favor of God.

Adaptation in hearing: When we enter a noisy environment, we are disturbed by the extreme noise. But two tiny muscles located in the middle ear contract as a manifestation of His mercy and prevent the sounds from being conveyed to the middle ear by masking all the sounds except for the ones of normal conversation. Workers in a noisy environment keep working as though they do not hear the noise at all.

Adaptation in feeling the pain: There is no adaptation in feeling the pain which is an indication of God’s mercy. If there were any adaptation to the pain, we would lose the patients before diagnosing and curing the illnesses. If a patient bothered by the gastrointestinal bleeding or appendicitis were to have an adaptation to the pain, after a few minutes he would not feel any pain before taken to the hospital and think that his illness is over and does not feel any need for a treatment. But possible inflammation of the appendix might result in the risk of death after a while.

Many of us are not aware of this perfect mechanism of adaptation. All these examples put forward the fact that the mechanisms bestowed upon our senses are very harmonious and adaptive to the working principles of our intellectual and spiritual faculties in the evaluation of various situations that we encounter in our life and they also show that humans were created as a whole. If we were deprived of such a blessing, we wouldn’t be aware of many changes that threaten our life and be bothered by the disturbing environmental conditions.

Omer Arifagaoglu is a professor of medicine. He lives in Turkey.

By answering this argument we shall show that we do indeed accept the same biological facts, but do not agree about the ‘laws’ which try to explain them, nor about the limits and qualifications for the operation of those ‘laws’.

Unlike other Scriptures which claim Divine authority, there is no proposition in the Qur’an which can be contradicted by established scientific knowledge as untrue. The Qur’an does not underestimate the importance of reflection and argument, but it does indicate that our suppositions about the origin of creation cannot explain the reality of it: we simply were not present there.

I called them not to witness the creation of the heavens and the earth, nor their own creation: Nor is it for Me to take as helpers such as lead (men) astray (al-Kahf 18.51).

This verse should not be interpreted to mean ‘Do not ask questions or do not research’, for the Qur’an encourages scientific research explicitly. It is, rather, a warning about those who vainly claim to explain the phenomena which happen outside the normal course of events and cannot be described in terms of material causes and effects. Since the creation is the great, inclusive miracle, human beings can neither imitate it (that is, they cannot create out of nothing) nor explain it. To attribute the creation to God makes everything plausible and saves scientific inquiry from fruitless uncertainties and insecure speculations. To understand the basic principles of the reality of creation is most important. If they are properly understood, useful and worthwhile aspects of the theory of evolution can be sifted out from pretentious and false interpretations of it. For, in every idea, even if it is against common sense in general, there are some elements of truth. The biological facts, rightly so called, such as variation, adaptation, natural selection and mutation, in evolution theory, should be differentiated from the ideological and metaphysical baggage they have accumulated.

In our approach, evolution may be described as the changes and variations in the form of creatures, especially in living beings, and the genetic and environmental factors associated with those changes. We do not assert that living beings are fixed and unchangeable in their forms. To claim that would imply a limitation upon the knowledge and power of God which is contradictory to His Names, the All-Knowing and the All-Powerful. The creation reflects His Names through its novelty within renewal, its prolific variety amid abundance. Individual diversity is programmed into the genetic mechanisms which, as they unfold and evolve under the prompting of environmental factors, display (for our admiration and understanding) the action in the world of Divine grace and power. The many hundreds of apples on a single tree are not identical, nor are they identical over different seasons-they are only similar. Thus, the first emphasis in our definition of the concept of evolution is change which is vital for the maintenance of ecological diversity and balance.

To paraphrase the Qur’an: God imposes the law of change and evolution as a basic principle in the universe. In the enforcement of this law, He creates pairs and opposites which, interacting according to subtle purposes, are placed in the core of every being. Thus, the change-dependent evolution and the dynamic balance in the universe, have been realized through the intersection of the opposites continually since the outset of creation. There are many verses in the Qur’an (for example in Chapter 55, al-Rahman) which indicate change and balance.

The ideologues of evolution theory, however, ignore the Divine wisdom, measure and purpose in the universe, claiming that the change they observe is an effect of coincidences-random variations, aimless mutations.

In the light of recent findings, we know the apparent causes of change to be mutations, which are the hereditary alternations in the genetic information; the differentiation of an isolated population from its ancestor through multiplying inside the population; adaptation and so-called ‘natural selection’, that is the decrease or extinction of generations which are weak and unable to reproduce in their immediate environment.

Believers in the One God affirm that everything, from subatomic particles to galaxies, is created by Him, that He is Omniscient and Omnipotent, and everything acts under His will and command. Causes are created by God in the appropriate time and space and the appropriate order and combination as a sort of veil for His dignity and might. He only says ‘Be!’, and all the material causes, such as heat, moisture, air, chemical elements, radiation, etc., are. If such causes are seen in this way, if their being brought together into an order is understood to be a response to their need (their prayer) to participate in a collaborative universe-and if their being causes is confirmed by observations and experiments-then, we may regard causes as a useful way to explain biological phenomena.

We know that diversity in a species is realized through mutations in the genetic program, arranged by Divine wisdom, not by coincidence. The evolutionist idea that the mutations are arbitrary, that useful changes can occur by sheer chance and lead to the development of a living being, or that a lot of random mutations can accumulate to enable a sudden leap from one species to another, has not been confirmed by experiments and observations. To accept that the mutations are arbitrary interferences in the genetic order is like accepting that a rocket can be generated out of a sound aircraft by raking it randomly with machine-gun fire. Certainly, computer-aided probability calculations show that it is impossible for thousands of random mutations to accumulate on a living being and change it into another species. Any such change is manifestly against that organism’s survival and would have to overwhelm it suddenly, not gradually.

Some bacteria can be given the ability to synthesize insulin by means of genetic engineering. This is a kind of planned mutation. Such a transfer of ability is, though remarkable, a relatively small change: it is, in any case, only possible because of the relevant ability being present in the genetic material being transferred. It is sheer arrogance to claim that living beings having millions of such able genes have evolved from each other by arbitrary, random mutations.

Adaptation is a biological manifestation of the flexibility coded into the genetic programs of living organisms; it carries the potential, within the limits of the species, for the organism to survive in changing conditions and to sustain that survival through reproduction.

When environmental conditions change, responsive adaptations occur- e.g. change of colour or density of hair, size of ears-in proportion to the flexibility of the organism’s genetic potential. If the organism cannot adapt adequately, the species does not mutate into some new species, it goes extinct. That is what happened, we presume, to dinosaurs and dodos.

The diversity of various human races can also be explained by the flexibility of their genetic potentials in response to different geographical, climatic and environmental conditions, provided, as before, that the changes are contained within species boundaries. Intermarriages between the various races add to the diversity within the species boundaries, they do not yield another species. The working of genetic potential can also be seen in the way that insects adapt to pesticides, and certain bacteria acquire a nearly invincible resistance to particular antibiotics. Insects or bacteria become more resistant, but they do not become different species. Their potential for adaptation is understood, by believers, as a power to survive given to them by Divine Wisdom.

We do not wholly reject the concept of natural selection. However, it is necessary to criticize the extreme interpretation evolutionists make of it. First of all, there is not an absolute ‘cruel competition’ in nature which the strong dominate absolutely, nor a pitiless ‘selection’ process of exterminating rivals in the struggle for food (survival). Rather, there is a dynamic balance among the great variety of creatures which is characterized, overall, by mutual collaboration and solidarity. The killing of weak creatures by the stronger ones is not random, nor characterized by a drive to exterminate and monopolize resources for survival. On the contrary, it is, overall, purposive and beneficial. Predators prey, generally, on weak and sick animals, and this ‘selects’ the fit and healthy for survival and, quite probably, prevents epidemics within and between species. Also, it is manifestly obvious that the apparent ‘competition’ in nature is the outward face of a subtle and complex feeding chain which is vital for the overall balance of the ecosystem, providing niches for great numbers of species, not least those which feed on the left-overs of others thus cleansing and purifying the food-chain.

Another factor affecting natural selection is the difference in rates of breeding. One bacterium multiplies by millions in one day, a fly by thousands in two days. Vertebrates, except fish and amphibians on the other hand, breed far more slowly. From the base of the food pyramid to the top, the production of food increases in quality but decreases in mass, and consequently a lot of tiny living organisms are the food of larger ones. The difference in breeding rates among members of the same species causes rapid multiplying of a certain group, but not the change of its species. An organism with many young has more opportunity to survive in changing environmental conditions, because when the number of its young increases, so too do the combinations of genetic characters. Even after drastic environmental changes, a few may survive.

The concepts used by evolutionists used to explain biological realities have a merely nominal reality, they are far from being ultimate causes. Attributing reality or, worse, Divine power to concepts which can be useful only for building mental models, and ignoring the knowledge, might and eternal wisdom of the Creator, means binding our hearts and minds to nature, like nature-worshippers and polytheists generally.
