Medical Teachings of Moses

Medical Teachings of Moses
Roy Nance of Murphreesboro, Tennessee, has spent a lifetime investigating the scientific credibility of the Torah. One of the areas he has specialized in is the medical teachings of Moses in the context of the time and culture in which he lived.

In his lectures, Nance discusses the Egyptian medical journals discovered by archaeologists over the centuries. Lee Strobel has discussed many of these in his books, and also Dr. S.I. McMillan discussed some of them in a book he wrote over 50 years ago titled None of These Diseases.

The Egyptian list of medicinal materials includes lizard blood, the blood of worms, swine teeth, putrid meat, pig ear moisture, goose grease, and the excrement of various animals. Moses grew up in the Egyptian culture that used these materials in medical treatment. In spite of his Egyptian education and the culture in which he was raised, Moses gave hygienic laws and practices that not only contradicted the teachings of his day but are correct by today’s standards.

The results of treating infections and cuts of all kinds with animal products had to be catastrophic, and the writings of Moses contain none of that. We understand the list of “unclean” animals in Leviticus 11. We see the importance of burying waste instead of throwing it into the street. Other hygiene standards presented by Moses are correct.

One of the most interesting of the teachings of Moses is the instruction for the timing of circumcision. Infants have two chemicals that develop in their bodies to allow clotting. Vitamin K is one, which at birth is at only about 20% of the adult level. The other is prothrombin which is at about 30% of the adult level by the fourth day of life. It isn’t until the eighth day that these two chemicals reach the adult level. Leviticus 12:3 says to circumcise boys on the eighth day. The timing couldn’t be better.

Skeptics have tried to minimize the credibility of the hygienic and medical teachings of Moses. In our day of epidemics of STDs and a variety of cancers endemic to certain lifestyles, the wisdom of Moses continues to shine. We would suggest that is because his instructions came from God–not by trial and error.

Neanderthal Genes

Neanderthal Genes
There has been a lot of confusion about the Neanderthals in both religious publications and scientific writings. Scientists have reported that there are Neanderthal genes in modern humans.
Many have treated the Neanderthals as ape-men, and there have been multiple theories about how they originated.

Religious publications have speculated about Neanderthal influence on biblical characters. Those who wish to find “giants” in biblical accounts have claimed that the Neanderthals were giants, and at least one set of fake pictures of huge skulls has circulated on the internet attempting to back that up.

Researchers in Germany have just reported on DNA studies of the Neanderthal genes in modern humans. They found 15 Neanderthal DNA traits in modern humans. What is interesting is that these 15 traits show up in people of British ancestry, but people of pure African descent have no Neanderthal DNA. This will certainly complicate some of the “out of Africa” theories about the origin of humans.

We suggest that most of the claims of prehistoric humans involve racial variations. No claim of different species of humans is supported by the evidence. The biblical claim that Eve is the mother of all humans (Genesis 3:20) continues to be strongly supported as we study our past.

Incredible Color

Incredible Color
Our ability to see the incredible color in the world around us is amazingly complex. We don’t actually see color with our eyes. We see color with our brains.

Most humans have trichromatic vision. Our eyes only detect red, green and blue. If our eyes detect a lot of red and green but not much blue, our brains decide that we are seeing yellow. When our eyes register equal amounts of red, green, and blue, our brain decides that we are seeing gray. If red and blue are present, but not much green, our brain decides we are seeing purple.

Some of us do not have red or green receptors in our eyes, especially people with XY chromosomes (males). We call it color blindness, but in reality, our eyes just don’t see one particular set of wavelengths. Some of us with XX chromosomes (females) may have tetrachromacy which means we see more than the three primary colors.

In the animal world, color is produced by many different techniques. The wings of the Morpho butterfly appear to be blue or violet depending on how the light strikes them. This is due to light-scattering scales that cover the insect’s wings. Dragonfly wings look similar to the Morpho wings, but the dragonfly’s color comes from waxy crystals that cover layers of the pigment melanin. We call the method of color production in these insects “structural color” because it is produced by the structure of the material rather than by pigments. Cameleons also use structural color using nanocrystals in their skin. They can tune the nanocrystals to reflect different colors. In this way, they can match the color of their environment or their mood.

We use color in many different ways such as camouflage, disguising foods to avoid their natural look, and to identify things. Much of the color that we see in the world has no practical value. For the most part, beauty is not a survival attribute. Evolutionary models attempt to explain some of the coloration we see around us, but in many cases, color is not a survival factor. Incredible color may be simply an expression of God’s desire for us to see the beauty and the majesty of His creation.

NASA’s Creation Account

NASAs Creation Account
Each day NASA posts an interesting astronomy picture of the day at www.apod.nasa.gov. The picture for October 24, 2017, shows the periodic table of the elements. NASA captioned the picture with a summary of the current scientific theories about the formation of the elements of the periodic chart were formed. We call it NASA’s creation account.

It may be that some will want to simply say God did it by “speaking it into existence.” Of course, NASA does not mention God, but their summary does not in any way denigrate God or the way He works. This brief summary demonstrates the majesty and power required to form the creation. The fact that the process has no scientific explanation of an ultimate cause lends support to the statement, “The heavens declare the glory of God and the cosmos declares the work of His hands. Day after day they pour forth speech: night after night they display knowledge” (Psalms 19:1-2).

Here is the summary which you can read on NASA’s website:

“The hydrogen in your body, present in every molecule of water, came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in your body was made during supernovas of stars that occurred long ago and far away. The gold in your jewelry was likely made from neutron stars during collisions that may have been visible as short-duration gamma-ray bursts or gravitational wave events. Elements like phosphorus and copper are present in our bodies in only small amounts but are essential to the functioning of all known life. The sites of nuclear creation of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.”

We don’t see a conflict between NASA’s creation account and the one found in Genesis 1. The more we learn about the creation, the more we can say, “So that’s how God did it.”

Most Sophisticated Visual System

Most Sophisticated Visual System
You might be surprised to know what animal has the most sophisticated visual system. Its eyes have at least twice as many types of color receptors compared to human eyes. They have three focal points while human eyes have only one. This animal can see both ultraviolet and infrared light, which our eyes cannot do. It has six polarization channels in each eye with high polarization sensitivity and hyperspectral imaging. What is the animal with this incredible visual system? It’s the mantis shrimp–a marine crustacean of the order Stomatopoda.

Researchers studying this animal’s eye say that it not only surpasses the sensitivity of our own visual system, but also captures more visual information, uses less power, and takes up less space than the most sophisticated state-of-the-art cameras. Scientists at the University of Illinois have developed a color-polarization camera based on the mantis shrimp’s visual system. The camera can aid in the early detection of cancer.

Mantis shrimps communicate using polarized light which cannot be detected by predators. They polarize the light by sending it across a reflector rather than the conventional method of sending the light through a lens. Researchers are copying this method of the mantis shrimp to develop a single chip, low-power, high-resolution color-polarization camera. The National Science Foundation and the Air Force Office of Scientific Research are sponsoring the project. The mantis-copied camera concept has great potential for a variety of applications.

Romans 1:19-20 tells us we can know there is a God through the things He has made. Again and again, scientists discover design’s like the most sophisticated visual system of the mantis shrimp. These amazing discoveries happen in every discipline of science. It is an exciting time to be alive, as we see more and more examples of God’s creative wisdom and design.

Orionid Meteor Shower

Orionid Meteor Shower
The Orionid meteor shower has just passed its peak for 2017. The “shooting stars” that are visible in this annual event are not stars, but they are comet debris.

Halley’s comet (1P/Halley) passes within sight of Earth about every 75 to 76 years. Like all comets, it leaves behind a trail of small rocks that have fallen away. Every year at this time Earth’s rotation around the Sun causes us to pass through that trail of debris. Comet pieces are pulled in by Earth’s gravity, and they burn up because of friction with our atmosphere. We see the streaks across the sky, and since they seem to come from the direction of the Orion constellation, we call it the Orionid meteor shower.

Two years ago I was able to “catch a falling star” on camera. You can see the one I caught streaking downward from Orion’s left foot. In case you have trouble seeing Orion, the hunter, I have added labels to the second picture.

I think Orion is interesting because God talks about it in Job 38:31. God finally speaks in answer to Job and his friends, and God asks Job a bunch of questions that Job can’t answer. Among those questions, “Can you loose the cords of Orion? Can you bring forth the constellations in their season?” In other words, “Can you untie the belt of Orion?” Of course, Job could not. Nor could he do any of the other things in the questions God asked of him in chapters 38 and 39. Only God can.

The point God was trying to get across to Job is that God is in control and we need to trust Him, even when we can’t understand why things don’t go the way we think they should. Job finally understood that and said, “Surely I spoke of things I did not understand, things too wonderful for me to know” (Job 42:3).

There are events in the world and in my life that make me wonder why God allows those things to happen. Orion reminds me that I am not in control, but God is. Like Job, I have to realize that there are things I just don’t understand. The Orionid meteor shower is a yearly reminder of that.

Origin of Life Complexity

Origin of Life Complexity
The origin of life complexity continues to baffle science. There are two competing scientific theories on the origin of life. One is called the “Darwin school of thought” which posits that meteorites brought elements to Earth that led to the formation of compounds which led to RNA and then to DNA. The second theory says that life originated in mineral-rich hydrothermal vents on the ocean floor.

The problem with both of these theories is that they are not explaining the origin of life complexity. They are only explaining some of the compounds that would be necessary to form life. Many scientists question the possibility of either of these theories and whether organic compounds could survive in the conditions of the early Earth. The bigger issue is how you could move from those compounds–no matter how they were formed–to a living cell.

You not only must have the ingredients to make life, but you also need a protected environment in which those compounds can be combined. Life could not begin in a toxic atmosphere or if there were agents on Earth’s surface that would destroy the ingredients. RNA and DNA involve long strands of nucleotides. Scientists in the laboratory can only produce such chains in a carefully controlled environment. The time element involved in producing increasingly complex molecules is also an issue.

When we enter probabilities into this process, the odds of each step happening by chance are very unlikely. Then to put all the steps together in the right order makes the probability of it happening by chance outside the scientific limits of what is possible.

Research into the origin of life complexity strongly points to an intelligent Creator. The more we learn, the more complexity we see. The famous atheist Antony Flew saw the complexity of a living cell, and that was a major factor in his coming to believe in God. His statement of faith was, “You have to go where the evidence leads.” Certainly, this area of study gives evidence of God’s wisdom and creative design.

Evidence for God’s Existence

Evidence for God's Existence
Something that amazes me as I answer the questions and hate mail from our website is the incredible ignorance of not only the Bible but of the evidence for God’s existence.

Atheists are fond of saying “there is no scientific evidence for God’s existence.” Then they attempt to vilify Christianity by pointing to things done by people who claim to be Christians. With the growing number of atheist websites and the increasing participation of the media in these claims, people have embraced the idea that these notions are true.

You can find evidence for God’s existence in virtually every discipline of science. Genesis 1:1 gives us a series of choices that we must focus on to support faith in God. The account tells us that the universe had a beginning, that the beginning was caused, and that God caused it. The first two statements are scientifically addressable. Science has shown that there was a beginning. The evidence that time, space, and energy are not eternal is overwhelming. In our printed magazine, on our websites, and in our courses, we offer evidence for these statements. These choices do not require the Bible or any assumptions about God, so the assertion that we are just “spouting scripture” is not true.

Whether the cause of the beginning was God is a more complex issue because it is rooted in understanding God’s nature. Quantum mechanics, the work of Einstein, and modern work in physics have given us wonderful tools to understand the cosmos. The Bible becomes a necessary tool as we consider whether the biblical description of God fits the evidence that we see in the science disciplines. Most people have not fully grasped the concept of a being outside of time and space with the capacity to design intelligently all that we see around us. Their concept of God is simply too small, and that is true of atheists and believers alike.

Our primary goal is to encourage people to examine the evidence for God’s existence with an open mind. If people realize that materialism and naturalism may not hold all of the answers to the mysteries of creation, they may gain a mustard seed of faith that can move the mountain of disbelief.

Dangers of Long-term Marijuana Use

Dangers of Long-term Marijuana Use
A newly released study indicates the dangers of long-term marijuana use. The bottom line is that it alters brain cells.

The study was published in Jneurosci (The Journal of Neuroscience) on October 16. The researchers focused on the ventral tegmental area (VTA) of the brain. Dopamine and serotonin receptors are concentrated there. Those receptors give a person the sensation of pleasure.

The scientists conducted the study on mice in their “teen” and “adolescent” stages of life. The mice received injections of THC (Tetrahydrocannabinol) every day for a week. THC is the principal psychoactive ingredient in marijuana. Marijuana (as well as opioids and alcohol) stimulates the VTA to release dopamine resulting in an experience of pleasure and the desire for more. There is a GABA (gamma-aminobutyric acid) cell in the VTA which acts as an inhibitor. When the brain releases GABA, it serves to restrain the desire for pleasure and keep it under control.

In the week of receiving THC, the GABA neurons lost their ability to control the desire for pleasure. They were in a state of “long-term depression” (LTD). This caused the dopamine to remain longer in the VTA giving a sense of being “spaced out,” and leading to addiction.

The researchers stated that the long-term effect of the THC was to remodel the brain’s synapses resulting in reduced “synaptic plasticity.” The synapses carry electrical or chemical signals from one nerve cell (neuron) to another. This “synaptic modification” is changing the brain at the cellular level.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) is published by the American Psychiatric Association, and it is the standard reference used by mental health professionals at all levels. The current edition is DSM-5. It defines cannabis (marijuana) use disorder as a “problematic pattern of cannabis use leading to clinically significant impairment or distress.”

In other words, marijuana impairs the ability of people to do things they need to do or even want to do. We have cautioned before about the dangers of long-term marijuana use and the consequences of legalization and wide-spread availability. This study confirms that danger.

Martian Global Aurora

Martian Global Aurora
On October 6 NASA’s daily space news website apod.nasa.gov contained pictures of a Martian global aurora. Because Mars has virtually no magnetic field, the radiation level goes sky high during solar storms. In the latest storm, radiation levels doubled–which would have been dangerous to life on Mars.

Earth’s magnetic field is very strong, and deflects radiation coming from the Sun. The radiation is deflected toward the poles, which is why we see the auroras near the poles. By deflecting the radiation, the magnetic field protects life on the Earth from dangerous levels. The more we learn about the cosmos, the more we see factors that make life possible on Earth. Our magnetic field is one more example of the design of our planet.

Looking for life in space is not just about whether there is water on a planet. There are a huge number of other factors that must be present. A strong magnetic field to shield from radiation is just one of those factors. Of course, an atmosphere suitable for life is also a requirement. NASA has a space probe called MAVEN (Mars Atmosphere and Volatile EvolutioN) orbiting Mars. The purpose is to find out if Mars lost its atmosphere due to not having a strong magnetic field.

The Martian global aurora is just one more reminder of the blessing of life on planet Earth. It also indicates that life on this planet is no accident.
