Eugenics and CRISPR

Eugenics Logo 1921
In 1927 Supreme Court Justice Oliver Wendell Holmes stated: “Three generations of imbeciles is enough.” He was explaining the court’s support of a Virginia program of involuntary sterilization in a case identified as Buck vs. Bell. The Virginia law and others like it in other states compelled the involuntary sterilization of those people deemed genetically inferior. More than 60,000 people in the United States were sterilized in compliance with the laws the Supreme Court upheld. It was connected to the eugenics movement.

The concept of eugenics goes back at least to the ancient Greeks, but it became a popular movement in Europe and North America in the early twentieth century. In 1931, advocates of eugenics, the movement to improve the genetic quality of the human population, held a “Better Babies” contest in Washington D.C. to popularize the movement. Adolf Hitler used the concept of eugenics to justify his promotion of one superior racial group and to eliminate the inferior groups.

Now in 2018, the concept of using science to produce superior human beings is even more realistic. That is because of a gene-editing tool called CRISPR which geneticists can use to manipulate DNA to control the traits of animals, plants, and people. Dr. Henry Greely of Stanford University says that CRISPR “might one day be used to engineer humans who are more intelligent, beautiful, or athletic.”

It is essential to understand that the potential for good with CRISPR is enormous. It may be possible to cure genetic diseases by using gene editing techniques. It may also be possible to produce useful new food sources. The problem is that gene editing can also be used for evil purposes. Dr. Greely’s statement brings to mind Adolph Hitler’s justification of the extermination of what Hitler considered to be inferior humans.

So what will CRISPR be used for – enormous good, or enormous evil? The answer to that cannot come from science. The religious convictions of those doing the research and those who use the research will decide whether CRISPR does good, or whether it will become a tool of war and ethnic persecution.

Virtually every significant discovery of science can be used for good or evil. Nuclear energy has the potential for enormous good by providing unlimited energy to everyone on the planet. It also has the potential for immense destruction. Dr. Jennifer Doudna at the University of California, Berkeley, is one of the inventors of CRISPR. She has written that she has nightmares “of all the ways in which our hard work might be perverted.”

It is essential that brilliant young Christians become involved in science. They must be involved not only in the research but also in how to use the products of the research.

Troposphere and Breathing Comfort

Troposphere and Breathing Comfort
Earth’s atmosphere is incredible! There are three primary layers of the atmosphere, and we live in the bottom layer called the troposphere. It extends as high as about 33,000-43,000 feet (10-13 kilometers). This layer is where we have breathable air. Above the troposphere is the stratosphere and above that is the mesosphere.

The troposphere is not only where we have air we can breathe, but it is also where we have weather and clouds. In the stratosphere, the air is not dense enough to supply us with sufficient oxygen, but it is relatively peaceful with little turbulence. In the early days of commercial airplane flight, because of turbulence in the troposphere, many people became airsick. However, planes could not fly above the troposphere because, among other problems, the low air pressure in the stratosphere would create a lack of oxygen for breathing.

That changed in the 1930’s when the Boeing company designed the first successful airplane with a pressurized cabin. They called it the “Stratoliner.” It could fly above the turbulence and still provide breathing comfort. Today commercial passenger planes fly in the lower stratosphere for cruising comfort, with pressurized cabins for breathing comfort.

When the weather on Earth becomes turbulent, we sometimes complain, but we can be thankful that the Designer of the Earth gave us a pressurized zone. With each breath we take, we should be thankful.

Circadian Rhythm of the Biological Clock

Biological Clock and Circadian Rhythm
Living things, both plants and animals, have a biological clock that is extremely important for survival. The human master clock is located in the hypothalamus of the brain in a tiny region called the suprachiasmatic nucleus (SCN). The SCN controls what is known as the circadian rhythm, a 24-hour rhythm of the body.

The SCN interacts with many regions of the brain to control sleep, hormone levels, alertness, body temperature, digestive activity, immune functions, and other systems. It coordinates the various rhythms of the body to keep us going through the day. This biological clock works in many ways that we don’t even realize.

Specialized cells in the retina of the eye connect directly to the SCN. When the eye senses light, the SCN receives the message and starts body process going by telling the various systems what to do and when. When you wake up in the morning, the clock signals enzymes to start flowing for your first meal. Hormones raise body temperature and blood pressure so that you can face the day.

During the day, the biological clock starts various chemicals and hormones so they will be available and functioning when they’re needed. Therapeutic medicines work best when taken at certain optimum times according to the biological clock. At night the circadian rhythm in the SCN sends a message to the pineal gland to produce the hormone melatonin making us sleepy.

This is a highly-simplified summary of an amazingly complicated system. Complex systems like this don’t happen by chance indicating that this is another evidence of design. Day and night, months and seasons regulate the systems of humans and all other creatures. Genesis 1:11 tells us that God made the Sun and Moon to “mark seasons and days and years.” Those simple words contain profound truths that we have only begun to understand.

STD Rates Increasing

STD Rates Increasing

In August 2018, the Center for Disease Control released 2017 data showing STD rates increasing. The report showed a radical increase in the sexually transmitted diseases chlamydia, gonorrhea, and syphilis. The CDC says that 2.29 million new cases of these three common sexually transmitted diseases were diagnosed in 2017. Gonorrhea led the way with a 19% increase in cases in that year.

The CDC suggests that the reason for the STD rates increasing is a lack of government funding on sex education. There has been no increase in federal spending in that area since 2013. We would suggest that education about the mechanics of how to avoid STDs won’t change the trend. People won’t change their behavior until they truly understand the purpose of sex and how sexual behavior functions in committed relationships.

We have pointed out before that more and more Americans say “none” when asked about their religious affiliation. That is especially true for the younger generation. Without a religious basis, how can young people understand that sex is a creation of God that binds parents together in a loving, healthy home? The answer to STD rates increasing is not more funding, but more faith.

Psychic Tears – The Third Type

Psychic Tears – The Third Type
Yesterday we mentioned that we have three types of tears. The first type is basal tears which lubricate the eye. The second is reflex tears which help to flush irritants from the eye. Each of those types has a different chemical composition. There is also a third unique type of tears. We call them PSYCHIC TEARS.

These tears are produced by intense emotional stress which can be pleasure, anger, suffering, mourning, or pain. Again, they have a different chemical composition from basal or reflex tears. These tears contain large amounts of protein-based hormones – prolactin, adrenocorticotropic hormone, and leu-enkephalin which is a natural painkiller.

The hypothalamus in the brain has a degree of control over the autonomic nervous system. In a complex process involving neurotransmitters and receptors, the lacrimal gland is stimulated to produce tears. Studies have shown that the shedding of psychic tears is a significant part of the emotional adjustment to stress. Ongoing studies are examining whether mental illness can be affected by the shedding of psychic tears.

We would never have thought that tears could be so complicated. We also find it interesting that tears have different connotations in the Bible. In Luke 7:38 a woman washes the feet of Jesus with her tears. Mark 9:24 tells of a father crying out with tears. Acts 20:19 and 31 show tears used in a different context. Revelation 7:17 and 21:4 speak of God wiping away ALL tears indicating a realization of all the services that tears provide.

A study of tears is a beautiful reminder of David’s statement of Psalms 139:14: “I will praise you, God, for I am fearfully and wonderfully made: marvelous are your works.” Tears show us just one more example of God’s design of our bodies to cope with life on Earth.

Types of Tears – There are Three

Types of Tears – There are Three
In April of 2016, I received a note from Charles and Brenda Beard who asked if I had ever studied the subject of tears? I put that in my list of topics to investigate thinking that types of tears could not be very complicated. There should be only one type of tears that came with different kinds of situations. Upon researching tears, I have learned that there are three types of tears, and they are different in function and different in composition.

BASAL TEARS keep the cornea of the eye continually wet and nourished. They also lubricate the eye and keep it free of dust. Tears of this type contain water, mucin, lipids, lysozyme, lactoferrin, lipocalin, lacritin. immunoglobulins, glucose, urea, sodium, and potassium. The substances such as lysozyme fight against bacterial infection by dissolving a layer in the outer coating of certain types of bacteria. This action is part of the body’s complex immune system.

Basal tears also contain antioxidants including ascorbate, urate, cysteine, glutathione, and tyrosine. For those of us that aren’t biochemists, this simply means there is a complex, designed system in the tear production of our eyes. This system keeps this vulnerable, exposed surface from being destroyed by agents in the world around us that would attack such a sensitive area.

Typically a person will secrete .03-.04 ounces (.75-1.1 grams) of this body fluid per day. If you have had a family member or even a pet that could not produce tears, you know that very quickly the eye becomes unusable. Basal tears are a carefully compounded chemical substance essential to our vision.

REFLEX TEARS attempt to wash away anything that irritates the eyes. When foreign particles or irritants contact the eye or nasal area, TRP (amino acid) channels in the ophthalmic nerve act to produce these tears. Most of us have produced tears when working with certain substances such as when cutting onions. Tear gas, pepper spray, or some fragrances cause this same reaction. Yawning, coughing, or vomiting can trigger these tears. Bright lights shining in your eyes or hot, peppery substances in your mouth also trigger reflex tears. The fluid, which is water laced with amino acids, help to wash away the irritant.

Those are two types of tears that are very important. There is also a third type which we will talk about tomorrow.

Alcohol and Health Exhaustive Study

Alcohol and Health
The most exhaustive study of the long-term effects of alcohol has been released by King’s College, London, and the Chief Medical Officer of the United Kingdom. The study included 28 million people in 195 countries and included 694 separate studies. The research shows a strong connection between alcohol and health.

The report stated that “no amount of alcohol is safe to consume.” It went on to say: “The conclusions of the study are clear and unambiguous – alcohol is a colossal global health issue and small reductions in health-related harms at low levels of alcohol intake are outweighed by the increased risk of other health-related harms, including cancer. There is no safe level of alcohol consumption.”

The study shows that alcohol is the seventh leading risk factor for premature death and disease. Overall 2.2% of deaths in women and 6.8% of deaths in men come from alcohol-related cancers. The study also gives data for drinkers in different countries. Denmark had the highest usage with 95.3% of the women in Denmark and 97.1% of the men regularly using alcohol. Pakistan had the lowest with 0.8% of the men and 0.3%of the women in Bangladesh being regular drinkers. A standard drink was 10 grams of alcohol. Ukraine had the highest amount of alcohol consumed–8.2 drinks a day being consumed by the men in Ukraine and 4.2 drinks a day by the women. The report dealt with alcohol and health. Data on traffic accidents and alcohol is in addition to these health problems.

Like many other issues, Christians have to look at their responsibility to take care of their bodies. First Corinthians 3:16 tells us that our bodies are the temple of the Holy Spirit and that God condemns those things that destroy the temple. The cost of alcohol goes far beyond the purchase price. Medical expense, psychological damage, treatment expense, and accident expense make alcohol the most destructive drug in our world today.

The study shows that 32.5% of the world’s population drink alcohol which adds up to 2.4 billion people. What does it take for our world to realize the cost and speak against the use of alcohol? How can Christians take an ambiguous position on this issue? The wisest man who ever lived said it well, “Wine is a mocker, strong drink is raging: and whosoever is deceived by it is not wise” (Proverbs 20:1).

Digital to Biological Converter

Digital to Biological Converter
The speed of scientific advancement in genetics and the use of computers in biochemistry is astounding. Scientists mapped the human genome in 2001. In May of 2018, Synthetic Genomics announced that they had created a working Digital to Biological Converter (DBC). The DBC turns digitized DNA code into synthetic biological material such as proteins. The process is called “Gibson Assembly” and can produce small pieces of DNA code called oligonucleotides and stitch the pieces together into DNA strands.

The exciting part of this new technology is that it could allow doctors to personalize medications to the individual needs of patients. Oncologists could create a medicine specifically targeted to the patient’s tumor. It has the potential to create vaccines to fight an epidemic quickly. The prototype machine is too large and too inefficient to be practical, but Synthetic Genomics hopes to have it available to medical researchers in three to five years.

Many of the health problems we have today whether genetic or otherwise have been caused by what we have done to ourselves and our environment with various chemicals and carcinogens. Some might say that we are “playing God” by creating synthetic genetic material. But if we have a way to correct the damage that our ancestors and we have done and relieve pain and suffering, we should certainly do it. The complexity of the Digital to Biological Converter and the material that it produces tells us more of God’s wisdom in the original construction of life.

American Marijuana Attitude

American Marijuana Attitude
A recent study showed that most Americans view marijuana favorably thinking that it has significant benefits and few risks. Science does not support the new American marijuana attitude.

The journal Annals of Internal Medicine published the new study on July 23. The researchers conducted an online survey of more than 9,000 people from all over the United States. They found that 81 percent of U.S. adults believe that marijuana has at least one benefit. The most common benefit mentioned was pain management. Other supposed benefits in people’s minds were the treatment of diseases and relief from anxiety, stress, and depression. At the same time, 91 percent of the respondents believe that marijuana has at least one risk. The most common risk mentioned was not medical problems, but legal. They also mentioned addiction and impaired memory. The bottom line is that the American public sees marijuana as having few health risks and significant health benefits.

The prevailing favorable American marijuana attitude is most likely due to the influence of the media. Some individuals and businesses stand to make a massive amount of money on marijuana, and governments see it as a source of tax revenue. In the meantime, the public is ignoring costs in healthcare, addiction treatment, traffic enforcement, and traffic deaths. In a previous post, we reported on a study of the effects of marijuana on the brain. The American Medical Association published information in the JAMA Internal Medicine on the increase in fatal car accidents in the United States on April 20 each year. That’s the cannabis celebration day on which thousands of marijuana enthusiasts light up at 4:20 PM in celebration of pot. The 4/20 celebration has grown as marijuana has become more widely available and legal. According to the JAMA Internal Medicine journal, there was a 12 percent increase in fatal crashes on April 20 and a 38 percent increase among drivers younger than 21.

Since Washington state legalized recreational marijuana in 2012, the percentage of drivers involved in fatal crashes who had traces of marijuana in their blood has doubled. One of the problems involves trying to set a legal limit for marijuana because its effect on the body is very different from alcohol. Blood alcohol level reliably predicts impairment. The level of THC (the chemical in pot) in the blood is not the critical factor until it enters the tissue of the brain where it has its effect. The THC blood level may be lower when the brain is most affected.

Getting high on marijuana makes changes in the human brain and smoking the weed has many of the same health dangers as smoking tobacco. It seems clear that the American marijuana attitude is changing, but it is also clear that we need to step back and think more clearly before our thinking becomes blurred by pot.

Should Christians Care About Global Warming?

Should Christians Care About Global Warming?
Global warming has been an issue from a scientific perspective for at least 60 years. I remember discussions about it in my college classes at Indiana University many decades ago. In the last decade it has become a political issue and in the last few years a religious issue. There is so much bad information in the media that it is no wonder many people are confused about what is true and what is not true. Should Christians care about global warming?

Let us first point out that global warming and local heat are two different things. The heat wave that you may have experienced in the summer of 2018 in the United States is NOT what global warming is about. It may be hot where you are and very cold somewhere else. Global warming is just that–global. Data shows that the average temperature of the entire planet is rising. This is not the first time it has happened. The history of the planet shows periods of global cold and global heat. The causes of these changes are many and complex. Earth is a large planet with multiple factors involved in how its climatic systems work. Variations in the sun, volcanic eruptions, asteroid and comet collisions, and human activity all can affect climate.

Does climate affect human life? Of course it does. It always has, and with our increased population the effect will be greater. Jesus told his disciples, “You will hear of wars and rumors of wars: see and do not be alarmed for all these things will come to pass but the end is still to come. For nation will rise against nation, and kingdom against kingdom and there shall be famines and earthquakes in different parts of the world” (Matthew 24:6-7).

Is human life affecting climate and should Christians care about global warming? Genesis 2:15 tells us that God put humans in the garden of Eden “to dress it and keep it.” God expects us to take care of what He created, and we have not done a good job of it. When we mismanage God’s gift to us, there are always consequences. Man-made synthetics cause a large percentage of cancer. We are in an opioid crisis because of materials we take into our bodies that affect us in a variety of ways. Those of us who live in industrialized areas have seen the ecological disasters caused by human greed and selfishness. Several years ago, the Cuyahoga River in Ohio actually caught on fire. I have seen areas like Ducktown, Tennessee, and Sudbury, Ontario, decimated by pollution. Fortunately, people worked to clean up those places. Right now we have a crisis in our oceans because of the foolish disposal of plastics.

The global warming issue involves many factors, and human actions are certainly some of them. To what extent humans are responsible can be debated, but the question of rising temperatures globally cannot be debated. Christians can lead the world in helping relieve the consequences of “famines and earthquakes in different parts of the world.” If your belief system is “survival of the fittest,” you will not get involved, but that is not the worldview of Christians.

Jesus said, “Then shall the King say … Come you blessed of my Father, inherit the kingdom prepared for you from the foundation of the world: For I was hungered and you gave me food to eat: I was thirsty and you gave me something to drink: I was a stranger and you took me in: naked and you clothed me: I was sick and you visited me…” (Matthew 25:34-38). Global warming may cause much suffering on our planet, whatever its cause. Should Christians care about global warming? Yes, and the followers of Jesus Christ will be there to relieve the pain.
