Your DNA Code

It’s a program code written in four biological compounds that we identify with the initials A, G, T, and C. It’s three billion letters long. If you printed it on standard sheets of paper in 12-point font size and stacked those sheets, the stack would be as high as the Washington Monument (555 feet or 169 meters). What is the program? It’s your DNA code that gives the blueprint for your body.

If you spent ten hours per day seven days a week reading one letter per second, it would take you just under 75 years to read the entire program. In other words, it would require your lifetime to read the code that describes your physical blueprint. However, instead of being printed on paper, those four letters are paired in two-letter sets like the rungs of a 3-D spiral ladder. Then they are folded neatly into the nucleus of every cell of your body. Small changes in the coding of those letters could change the color of your hair or your eyes. It could change your body shape or size. It could determine if you have a physical or mental illness.

Your DNA code is comparable to that of every other person on Earth, but it is unique to you alone in many details. That’s why detectives use DNA forensic tests to determine the identity of a person who has committed a crime. Similarities in DNA can indicate who we are related to or where our ancestors originated.

Since the Human Genome Project completed the sequencing of human DNA in 2003, we have learned that our DNA is in many ways similar to that of other animals and insects, and even plants. Despite the similarities, there are significant differences that are not physical. Only humans have creativity, an appreciation for beauty, and a desire to worship. We believe that’s because God gave humans a special gift when He created us in His spiritual image, with a soul, not just a body.

We also believe that the enormous complexity of your DNA code could not have happened by chance. We suggest that the code that lays out the design of all living things was written by the same God who created humans in His image.

Six Elements and Three Interactions

You can find six elements in the cells of all living things: carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. Without all of those elements, life, as we know it, could not exist. Living things require many other elements to perform various functions to survive, but those six elements are the building blocks of living cells. Life depends on those six elements and three interactions.

What do those elements have in common? For one thing, they are all non-metals. More important is that those six elements have stable atoms that are not radioactive. Radioactive decay of the atoms of some elements releases alpha or beta particles, which are destructive to living tissue. When those particles enter living tissue, they cause the release of high-energy particles in the cells. That destroys DNA, causing disease and mutations.

We are exposed to some radiation every day, but the amount is usually small, and our cells have a remarkable ability to repair themselves. If any of the six elements released radiation particles, life could not exist. Why are these six elements so stable? We have to consider the six elements and three interactions.

Three carefully balanced forces or interactions work within every atom to give stability. They are the strong force, the weak force, and the electromagnetic force. The strong force binds protons together in the atomic nucleus. The weak force is responsible for radioactive decay. Electromagnetic interaction between the protons in the nucleus and the electrons holds those electrons in the atomic shell while allowing chemical interactions between elements.

The key to stability is the precise balance between the three forces. A change in the value of any of the three would upset the balance, making our atoms unstable and life impossible. Was it mere luck that caused the delicate balance of those forces? Is it possible that the balance and our existence are just chance accidents? We think a better explanation is that the Creator of the universe carefully designed the six elements and three interactions.

Other Galaxies Beyond the Milky Way

In the early 1920s, Edwin Hubble (in whose honor the Hubble Space Telescope was named) was peering through his telescope. As he examined many of the points of light that astronomers had thought were stars or “spiral nebulae” in our galaxy, he realized that they are much more than that. He discovered that they are other galaxies!

By the mid-1920s, everyone knew that our Milky Way is only one of a myriad of other galaxies. Since then, we have learned many things about our galaxy, but we still have much to learn. The Milky Way is a spiral galaxy in the shape of a large saucer. Other types of galaxies–which are the majority–cannot support planets and therefore are not suitable for life.

We are spinning around our spiral galaxy at about 120 miles (200 kilometers) per second. At that rate, it will take us 250,000,000 years to make one complete orbit of the galaxy. We can’t take a picture of the entire Milky Way because to travel outside of our galaxy would take many thousands of years–even at the speed of light. We can take pictures of other galaxies, and this one is another spiral galaxy named M74.

The Milky Way’s disk is about 100,000 light-years across, and we are about 27,200 light-years from the center. It’s good that we are not near the center because that is the location of a giant black hole. It is also fortunate that we live in an area of the galaxy that is not crowded with quasars, black holes, and other major hazards. The galaxy area with the most gas and dust is less than 500 light-years from the central plane–far away from us. That means we are in an area relatively free of debris, so this is an excellent spot to get a good view of our galaxy as well as other galaxies and stars.

Is it just a coincidence that we are in the right kind of galaxy and in the best position in that galaxy to be safe and to be able to study and observe the universe? We think God wanted us to be in a hospitable place where we could see the majesty of His creation.

Vanilla Mystery Solved by a Bee

The vanilla flavor used in many foods comes from an orchid (Vanilla planifolia) that originally grew in Mexico. Herman Cortes, a Spanish conquistador, discovered the pleasant-tasting substance used by the Aztecs, and he introduced it to Europe in the 1520s. But it took 300 years to solve the vanilla mystery.

When the Europeans tried to produce vanilla in their own countries, they could grow the vines, which produced flowers that bloomed one morning each year. However, within 12 hours, the flowers withered and produced no fruit. For three centuries, the vanilla mystery remained unsolved, and the Europeans depended on Mexico for vanilla flavor.

Then in 1836, a French botanist named Charles Francois Morren traveled to Mexico to study vanilla production. He noticed bees landing on the vanilla flower, working their way under a flap in the flower, and becoming dusted with pollen. Then they transferred the pollen to other flowers. Within hours of pollination, the flowers closed, and soon seed pods began to form.

The vanilla mystery solution was known only to those stingless bees of the genus Melipona which lived only in Mexico. They knew how to pollinate the flowers so that they could produce seed pods. The people who attempted to grow vanilla elsewhere tried without success to bring the bees into their areas. Then in 1841, a twelve-year-old slave boy discovered a way to hand pollinate the flowers using a sliver of bamboo. The vanilla mystery was solved!

Because of hand pollination, Indonesia and Madagascar now exceed Mexico in vanilla production. However, hand pollination is labor-intensive and requires constant monitoring of the plants since the flowers stay open for only a few hours. It took humans 300 years to discover how to pollinate the vanilla flower. Before that, only the Melipona bees knew the secret. No other insects knew how to enter those flowers and pollinate them.

Without the bees, there would have been no vanilla plant for humans to discover and use. More important, without the bees, the vanilla vines could not reproduce. Since the orchid could not survive without the bee, the question is, “Who put that bee there and told it how to pollinate that flower?” The vine and the bee could not have evolved separately. That leaves us with another vanilla mystery. Perhaps the bee and the vanilla vine were created to work together. We see this as another evidence of God’s creative work. Think about that the next time you enjoy some vanilla ice cream.

Solar Wind and Earth’s Magnetic Shield

For a hundred years, scientists looked for the answer to a perplexing question. In 1859 British astronomers observed what we now call a solar flare. The next day there was a disturbance of Earth’s magnetic field called a geomagnetic storm. Scientists were puzzled over what was happening. After a century of study, the answer came down to solar wind and Earth’s magnetic shield.

In 1958, American astrophysicist Eugene Parker described the phenomenon and named it “solar wind.” The solar wind consists of charged particles ejected from the corona (extended outer layer) of the Sun and traveling at high speed into space. This material is plasma, a mixture of negative electrons and positive ions. Since electric charges and magnetic fields interact, the planet’s magnetic field steers the solar wind away from the planet’s surface when it reaches Earth. Because Earth’s magnetic field originates from the North and South poles, we see the interaction in those regions as beautiful auroras, the Northern and Southern lights.

What if Earth did not have a magnetic field? The solar wind would reach Earth’s surface and significantly damage living cells, bringing an end to life. Our neighboring planets Venus, Mars, and Mercury have little or no magnetic field and therefore are bombarded by the solar wind.

Why is our planet different? Why do we have the protection of a magnetic field? The motion of the molten iron in Earth’s core produces the magnetic field. Why does Earth have a molten iron core? Heat generated by the decay of the radioactive elements uranium and thorium keeps the iron core from becoming solid.

The bottom line is this: Hidden inside our planet is a magnetic-field generator powered by unseen radioactivity that gives us an invisible magnetic shield protecting us from invisible destructive particles coming from the Sun. This same process also gives us beautiful auroras we enjoy watching. The solar wind and Earth’s magnetic shield give us one more example of the beautiful design of the planet we call home. Did this all happen by accident? We don’t think so.

Invasion of Amoral Intelligence!

Recently there have been many articles and news stories about Artificial Intelligence (AI). Some leading scientists are worried about what may happen in the future as machines or robots become available with higher levels of AI. Already we have “Weak AI” with computers and phones speaking in human-sounding voices and answering our questions. The next step is “Artificial General Intelligence.” That would be a general-purpose speaking machine that can think and perform specific tasks better and faster than humans. The main concern here is the loss of jobs that humans now perform. Perhaps we need to be concerned about an invasion of amoral intelligence.

What worries or even frightens some experts in the field is “Artificial Superintelligence.” We are talking about an artificial intellect that could outperform the most brilliant human minds, achieve new levels of creativity on its own, and display social skills that could not you could not distinguish from humans. It would be able to continue learning at a fantastic speed, shape its own future, and act in its own interest. Its desires and motivations could be very different from the interests of its creators or humanity as a whole. It could develop its own agenda even to the destruction of humans. This is the stuff of science fiction movies, and the current prediction is that somewhere between 2040 and 2050, science could achieve this level of AI.

Human life is guided by a conscience that our Creator put into us. Every human being recognizes that there are moral values and that some things are right and good and other things are wrong and evil. No matter if this moral sense becomes distorted by teaching, experiences, or even mental illness, it is still there. Even an atheist such as Princeton bioethicist Peter Singer has some limits, even though he argues that humans are just animals not deserving status above any other species and that parents should have a month to decide whether to keep or euthanize their newborn children. That seems like a shocking moral code, but an Artificial Superintelligence would not necessarily have even those moral limitations.

Humans have a built-in moral quality because God created us in His image. The result of humans making a machine with superhuman thinking abilities and no moral conscience should cause us to step back and carefully consider the possible invasion of amoral intelligence.

Bloodletting – Life Is In the Blood

For almost 2000 years, from ancient Greece to the nineteenth-century, the most common procedure performed by surgeons was bloodletting. The doctors would cut the patient to allow blood to drain because they thought this would drain disease from the body. In truth, if it didn’t kill the patients, bloodletting at least left them weaker. The medical establishment didn’t realize that life is in the blood.

Even though William Harvey disproved the effectiveness of bloodletting in 1628, doctors (and barbers) still practiced it for another 200 years. It can take a long time for false ideas to be abandoned, even by doctors and scientists. In some areas such as China and the Middle East, people still practice a form of bloodletting today known as hijama or cupping.

While they were still practicing bloodletting, doctors began to experiment with blood transfusions. Early experiments in the seventeenth-century involved transfusions of animal blood into humans, usually with disastrous results. Doctors didn’t realize that there are different blood types among humans and even among animals. Different blood types have a different molecular structure in the red blood cells. If a patient is given blood of the wrong type, it can cause a reaction that can be fatal, because the patient’s immune system attacks the foreign blood cells as invaders.

In 1901 Karl Landsteiner found that mixing blood from different patients sometimes caused clotting. This led him to classify blood into three types—A, B, and O. Scientists have discovered more blood groups since then, making transfusions much safer today.

If those who practiced bloodletting had paid more attention to the Bible, they might have realized much sooner that it was a bad idea. “The life of every creature is in the blood” is stated twice in Leviticus 17 verses 11 and 14. With that admonition, God commanded the ancient Israelites to refrain from eating blood and to sacrifice the blood of animals to cover their sins. But the final redemption for sins came when “God presented Christ as a sacrifice of atonement, through the shedding of his blood” (Romans 3:25). Life is in the blood, and eternal life is in the blood of Christ.

Quasar Brighter Than 100 Billion Stars

It’s 2.5 billion light-years away, and brighter than the over 100 billion stars in our Milky Way Galaxy combined. If it were even as close as 30 light-years from us, it would appear as bright as the Sun, which is only eight light minutes away. Before anyone ever saw it, scientists detected it by the radio waves that it sends out.

In 1963, astronomer Allan Sandage was the first to observe quasar 3C 273 with a telescope. Quasars are the brightest objects in the known universe. They’re massive discs of particles that surround a supermassive black hole at the center of a galaxy. They emit intensely powerful energy as the black hole sucks the life out of matter and pulls it into its abyss. The energy is brighter than 100 billion stars.

The cloudy streak in the picture from NASA’s Hubble Wide Field and Planetary Camera 2 is a jet of energy that was fired off by the quasar at some time in the past. That streak is 200,000 light-years long! It would be impossible to survive in a galaxy with a quasar in its center. The intense energy from the quasar would destroy life while the black hole devoured the matter. We can be thankful that this quasar is so far away, even though it is one of the nearest.

Life on Earth is possible because we have no black holes or quasars near us. We think the universe reveals the work of an amazing Master Designer. We agree with Dr. Allan Sandage, the first person to observe a quasar, when he said, “Science makes explicit the quite incredible natural order, the interconnections at many levels between the laws of physics…Why is the design that we see everywhere so truly miraculous?… As I said before, the world is too complicated in all its parts and interconnections to be due to chance alone.”

Christmas Holly Is a Reminder

It’s an evergreen tree that can live for 500 years and grow up to 33 feet (10 meters) tall. However, it usually doesn’t live for more than 100 years or grow taller than 10 feet (3 meters). It is often associated with Christmas because people use it in wreaths and garlands, and you see it pictured on many Christmas cards. What does European (or English) holly (Ilex aquifolium), also known as Christmas holly, have to do with Christmas?

The connection to Christmas goes back to medieval times in Europe. People said that the sharp-pointed evergreen leaves reminded them of the crown of thorns Christ was forced to wear at His crucifixion. The berries, which are red during the Christmas season, reminded them of the blood Christ shed, and the white flowers stand for purity.

European holly grows as a tree or a bush. The berries are mildly toxic to people and harmful to dogs or cats. However, they provide winter food for birds, rodents, and other animals. The flowers are sources of nectar for bees and butterflies. European holly grows in shady areas in forests, and it can form a dense thicket along forest borders. Because it is a dense evergreen with sharp points, people often use it for privacy hedges.

In its native areas of Europe and other regions, holly is an ornamental plant admired for its beauty. However, since people brought it to North America’s west coast, it has become an invasive species. It thrives in the shade of forests and crowds out species native to that area. Washington state has called it a weed.

Like other plant species, European holly has an ecological niche to fill. Problems often arise when people do something to upset the balanced relationship that God has designed into nature. From the beginning, humans have done things to upset our relationship with God. That brings us back to Christmas and the reason God came to Earth in the form of a human who lived a pure life and shed His blood on the cross to redeem us. Christmas holly reminds us of that.
