How to Stop the Aging Process

Stop the Aging Process
It’s scientifically impossible to stop the aging process. That is the conclusion of a new study reported in the Proceedings of the National Academy of Sciences on October 25, 2017. You can read the full report here.

The problem is defined mathematically in that report. It involves two forces that take place in multicellular organisms, such as humans. As cells reproduce, mutations accumulate causing the cell functions to become sluggish and lose function. The result is wrinkled skin, gray hair, weakened bones, and many other things. When the body’s cells are young, they cooperate to weed out imperfect cells. With age, there are more cells with imperfections, and the body can’t keep up with removing the bad ones. At the same time, some cells start to reproduce uncontrollably. We call it cancer. Either we have sluggish cells or out of control cell reproduction.

Removing the sluggish cells leaves more room for the out of control cancer cells. Removing the cancer cells leaves the sluggish cells. A balance between the two is not mathematically possible to sustain. Eventually, the math catches up with us and death results. According to the report, scientists who are looking for the cure for aging are not going to succeed. Of course, we all know that lotions, creams, vitamins, and health foods have limited success in keeping us looking and feeling young. According to the research, either your cells will become more sluggish, or they will become cancerous. There is no other option. There is no fountain of youth. You can’t stop the aging process.

But wait! Genesis 2:9 tells us about the trees in the Garden of Eden, and mentions two of them by name. God commanded the first couple not to eat from only one of those two. The other one that they could eat from was called the Tree of Life. When Adam and Eve were banished from the garden that God had prepared for them, they were cut off from the Tree of Life. God said that if they ate from it, they would live forever (Genesis 3:22). For them to live forever in their fallen state, separated from God, would be worse than death. On that fateful day, Adam and Eve died spiritually, and their bodies began to die physically. Ever since then, humans have tried to cheat death and live forever. The result has been a long history of failure.

But God had a better plan. He prepared a way to restore the descendants of the human race to Himself. He hinted at it in Genesis 3:15. The plan was revealed and completed by Jesus Christ. He set out to finish the task of restoration (John 4:34 and 5:36), and He did (John 19:30). We read in Revelation 22:1-2 about the River of Life flowing from the throne of God. Growing along the sides of that river we find the Tree of Life. No longer will it be out of reach. Until then–according to this scientific report–scientists are searching in vain to find a way to stop the aging process and death.

Different Shades of Brown

Different Shades of Brown
Racial prejudice based on skin color is a function of ignorance. I am amazed that promoters of violence against black-skinned people have daughters who are using tanning booths to get darker. There is no inferior race, and there are no different species of humans. Acts 17:26 tells us that God “has made of one blood all nations of men for to dwell on all the face of the earth…” We are all just different shades of brown.

Many years ago the preacher of the Central Church of Christ in Birmingham, Alabama, invited me to participate in a television panel discussion. The format was a call-in where callers could ask questions for the panel to answer. On the panel with me was the black president of a small African-American college in East Texas.

The discussion took place during the time of racial strife in Birmingham. A caller asked if black people were evolved apes and white people were created by God in His image. I responded by pointing out that apes and white people have more features in common than apes and black people. This includes hair texture, jaw shape, skull shape, and even skin color when you look under the hair. This produced some antagonism from our host but was followed by the question of why black people are black and white people are white.

I took my hand and laid it on a white sheet of paper and asked if I was really white? The answer, of course, was that I wasn’t white like the paper. I was light brown. Then I asked my black friend to lay his hand on the same sheet of paper, and I asked if he was really black? The answer was obvious. He was just a darker shade of brown. I then made the point that we are all just different shades of brown, and we are all equally created in God’s image.

My black friend leaned over and whispered in my ear as we looked into some rather hostile people at the TV station. He said, “Ain’t neither one of us getting out of here alive.” I am glad to say that we did.

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.

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.

Overwork Death

Overwork Death
Time magazine (October 23, 2017, page 14) had an interesting article about a Japanese problem called “karoshi” meaning overwork death. The term was coined in 1978 and became widely acknowledged in the 1980s.

Japan has a working culture in which many employees put in as much as 80 hours of overtime in a month. Japanese researchers claim that the annual fatalities from overworking are at 10,000 deaths a year. South Korea and China are also facing the same problem, and Turkey reports similar data. I suspect that the same problem is occurring in the United States.

Why is this happening? Is it perhaps the emphasis on things and materialism that has fueled a willingness to work more hours than our bodies can physically tolerate? Overworking contributes to heart attack and stroke. It also leads to stress and poor nutrition which cause even more physical problems. The Time article concludes that “a lifestyle is taking its toll.”

Christ taught us not to worry about the things of this world. Spending time in prayer, meditation, study, and service to others not only has spiritual value, but it has physical value as well. Maintaining a survival-of-the-fittest belief system can lead to overwork death, and it is destructive in more ways than we thought.

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.

Biological Clock Circadian Rhythm

Biological Clock Circadian Rhythm
Three scientists have just received Nobel Prize in medicine for proving scientifically something we knew all along. The scientists share the 1.1 million dollar prize for proving that we really do have a biological clock. The fact that you are alert at certain times and sleepy at others is not just in your head.

In 1984 they sequenced the “period gene” which others had discovered in fruit flies in 1971. The gene controls the circadian rhythm which regulates the daily sleep and wake patterns of all creatures, including humans. Following up on that work, in 1998 they found that the gene encodes a protein called PER. The PER levels build up at night and drop during the day. This discovery enables scientists to understand the molecular makeup of the biological clock.

Learning more about our biological clock leads to some useful understandings, including when is the best time to take certain medications. It also relates to shift work, jet-lag, and school classroom times. The understanding of circadian rhythms can be incorporated into practical medicine and the body’s production of melatonin, a hormone that prepares us for sleep.

A group of sleep researchers a few years ago did some research on biological clocks. They sent a group of volunteers on a tent-camping trip to the Colorado Rockies. They found that people who work indoors where they are not exposed to outdoor light may need to have their biological clocks reset. When people are indoors during the day and exposed to electric lights at night, their clock can become out of sync. Exposure to strong artificial light at night can delay our master clock. That delays the production of melatonin at night, and then the melatonin level is still high in the morning when it’s time to get up.

The campers were only allowed to use campfires for light and no cellphones or flashlights. After spending a week away from artificial light and exposed to more daylight, the volunteers fell asleep earlier and woke up earlier. Their melatonin levels rose earlier in the evening and dropped earlier in the morning.

The recommendation of the researchers was to start your day with a morning walk and when you have to be inside open the shades to get exposure to some sunlight. You may find that you will sleep better and wake up more refreshed.

“And God said, ‘Let there be lights in the expanse of the sky to separate the day from the night’…God set them in the expanse of the sky to give light on the earth, to govern the day and the night, and to separate light from darkness. And God saw that it was good” (Genesis 1:14, 17).

Cormorants Find Fish in Muddy Waters

Cormorants Find Fish in Muddy Waters
Several years ago a flock of cormorants arrived on the St. Joseph River near our home. The river was close to flood stage. The water was so muddy that you couldn’t see the bottom even if the water had been only an inch deep. Those birds demonstrated that cormorants find fish in muddy waters.

The birds landed in a large tree on an island in the middle of the river. Very soon after they landed, one took off and dove into the river. A minute or so later it came to the surface with a fish in its beak. For the rest of the day, we saw these fishing birds dive and catch fish, sometimes staying under water for a very long time. I wondered how they could do that because sight in the water was non-existent.

In the October/November 2017, issue of National Wildlife (page 8), there is an article explaining how cormorants and other fish-eating birds manage when the water is so loaded with mud that they can’t see. Scientists at the University of Southern Denmark have studied the hearing of the great cormorant. They discovered that this seabird has a specialized sense of hearing tuned to a very narrow frequency range. The frequency is the same as the sound produced by herring and sculpin fish as they swim in the water. Those fish are the primary prey of the cormorant and sculpin live on the bottom of water bodies where it is dark, and the water is often dirty.

There are over 800 species of birds that find their food underwater. Since these cormorants find fish in muddy waters, the scientists on this project predict that other aquatic birds also use specialized hearing to catch fish. We see this as another design that God gave these creatures for survival.
