An Octopus Garden

One of the more interesting creatures in the ocean is a small octopus called the pearl octopus (Muusoctopus robustus). They get their name because they look like pearls on the dark ocean floor. Because of their small size, they are easy victims of predation. They have no defense mechanisms and are an easy meal for various predatory ocean creatures. How do they continue to thrive in their Pacific Ocean habitat? The answer lies in an octopus garden.

Researchers discovered the octopus garden 80 miles from the central California coast at a place called the Davidson Seamount. A seamount is an ancient volcano that has either sunk into the ocean floor or has been covered by rising ocean water. The Monterey National Marine Sanctuary and Monterey Bay Aquarium Research Institute have studied deep-sea corals on this seamount for 20 years. They recently discovered an octopus garden – home to at least 6,000 nesting pearl octopuses and perhaps as many as 20,000.

The design of this “garden” offers successful reproduction of this vulnerable species. By being 10,500 feet down, they avoid many octopus predators simply because they don’t feed that deep. Like many other forms of life, synchronized birthing floods the area with offspring so a predator can’t wipe out a whole population. Hydrothermal springs at the base of Davidson Seamount warm the water, allowing the pearl octopus eggs to hatch much faster.

We see many remarkable designs in the biological world, allowing animals to survive. Every nook and cranny of the planet is home to some form of life, and this is just one more example. As Romans 1:20 says, “We can know there is a God through the things He has made.”

Siphonophores – A Colony of Animals Living as One

The more science learns about the biological world, the more unique things we see. Most of us know about jellyfish, corals, and anemones. These ocean animals are members of the phylum Cnidaria. In that phylum, a strange order named Siphonophorae has 175 species. The Portuguese man o’ war is a member of the order of siphonophores.

Siphonophores may look like one organism, but they are actually colonies consisting of thousands of clones that function in different ways. Siphonophores start with a single “bud” called a zooid. The zooid replicates itself asexually, producing thousands of clones. Each clone has a specific job, such as eating, moving, or reproducing.

The colony of clones functions together as if they were one animal. For example, the Portuguese man o’ war has gas-filled zooids, allowing it to float on the ocean’s surface. Other zooids capture prey, while others digest the food. The individual zooids rely on each other for survival as one large functioning colony we call the Portuguese man o’ war.

In 2020, scientists found a siphonophore that was 150 feet long, probably the world’s longest animal. Most siphonophores live in the darkness of the deep oceans and are bioluminescent, using chemicals to produce light that attracts prey. The Portuguese man o’ war is an exception as a siphonophore that lives on the ocean’s surface.

The deep sea diving expeditions of the Schmidt Ocean Institute and the EV Nautilus have taught us much about the designs built into living things that allow life to exist in places totally alien to humans. Siphonophores make us realize that planet Earth is a wonderfully designed and unique place in the universe, full of amazing living creatures. We must treasure God’s gift and take care of it instead of abusing and polluting it.

The Thymus and Adult Health

New research shows a connection between the thymus and adult health. When I was a child in the early 1940s, doctors performed surgeries on children to remove a gland or organ because they thought it was vestigial and no longer needed. By the time I was in high school, my tonsils, adenoids, and appendix had all been removed. When my daughter Wendy became a teenager, she had repeated throat issues and infections. Her doctor refused to remove her tonsils or adenoids even though they were infected and hurting her repeatedly.

We know now that the tonsils and adenoids are an important part of the lymphatic system, keeping our bodies healthy by trapping harmful bacteria and viruses. As we have come to understand the immune system in humans, we have found that surgically removing the tonsils and adenoids can open us to infections. New research indicates the same is true of the thymus.

The thymus is a gland in the chest between the lungs, in front of and above the heart. It produces immune cells called T cells that protect against foreign invaders that could cause illness. In children, the thymus is very active, but after puberty, it shrinks. By then, the body has memory T cells specialized in attacking intruders the body has fought before. Since the thymus gradually becomes smaller, it is frequently removed in heart operations because it gets in the way.

Oncologist David Scadden and colleagues at Massachusetts General Hospital in Boston researched the thymus and adult health. They examined the health outcomes of 1,146 patients who had their thymus removed at the hospital between 1993 and 2020. They compared those with an equal number of patients who had the same surgeries but did not have their thymus removed. The death rate for those whose thymus was removed was three times higher than those who did not. Thymus removal was also associated with two times the risk of cancer within five years.

The thymus serves a purpose in childhood but may play a different role in adulthood. The researchers don’t know the cause of these striking numbers, but they show a strong connection between the thymus and adult health. We now know that the appendix, tonsils, and adenoids contribute to the body’s immune system to help keep us healthy. It appears that we should add the thymus to that list.

Psalms 139:14 says, “I will praise you, God, for I am fearfully and wonderfully made: marvelous are your works..” We don’t have to look far to see God’s wisdom and design in creation. Just look in the mirror.

All These Things Will Be Dissolved

“But the day of the Lord will come as a thief in the night when the heavens will vanish with a great rushing sound, and the elements shall be scorched up and dissolved and the earth also and the works that are upon it will be laid bare – seeing that all these things shall be dissolved what devout and dedicated lives you should live.” – 2 Peter 3:10-11

As we study the creation and learn more about the mechanisms that guide natural functions, we realize that biblical statements of God’s methods are scientifically factual. The theologian may simply say that God does it and leave it at that. Those of us with a science background are interested to see how God designed a system to accomplish His purposes.

The statement of 2 Peter 3:10-11 is theological, but the description matches the latest scientific understanding of the nature of matter/energy. Scientific American magazine published an interesting article titled “Disappearing Act.” The article goes back to Stephen Hawking’s research, which showed that event horizons around black holes can emit “Hawking radiation,” which causes the black holes to evaporate.

Researchers in quantum mechanics have shown how the “Schwinger effect” can apply this concept of matter evaporating to any form of matter, not just black holes. If their calculations are correct, it means that anything with mass, which is everything in the creation, is designed so that it will eventually evaporate. Since God created time, the timing of this evaporation is not open to science.

Amazingly, the comment in 2 Peter that all these things will be dissolved cannot be seen as science fiction but as a picture of God’s creative power and wisdom of design. Indeed, the more we know of the creation, the more we comprehend the nature of the Creator.

A Lesson from the Dart Experiment

In September of 2022, NASA steered the DART spacecraft into an asteroid named Dimorphos, attempting to alter its orbit. The experiment was designed to see if we could change the path of an asteroid moving toward a collision with Earth. We can learn a lesson from the DART experiment.

It sounded like a good way to protect our planet from an asteroid impact. Scientists believe an asteroid collision may have caused the extinction of the dinosaurs, and a similar one might cause human extinction. The collision did alter the orbit of Dimorphos, which is comforting to know. However, it also caused more potential problems.

The Hubble Space Telescope observed 37 previously unseen objects accompanying Dimorphos in its orbit around the Sun. These are boulders probably blasted off from Dimorphos by the DART collision. They are not just little pieces of rock or dust. Some of the boulders are as large as seven meters in diameter. Calculations show that the weight of the 37 boulders adds up to 5,000 metric tons – the weight of 300 gravel-filled dump trucks.

This incident reminds us of the story of Frankenstein when a scientist created a being that turned into a monster. Dr. Frankenstein did not comprehend where his creation might go once it was out of his control. These boulders do not pose an immediate danger to the Earth but understand that meteorites striking Earth’s surface are generally quite small. The boulders caused by DART’s impact with Dimorphus would cause significant problems if they hit the Earth.

Humans can learn a lesson from this incident. We are not God, and our wisdom and knowledge are incomplete. As God said to Job, “Who is this that darkens counsel by words without knowledge?” (Job 38:2) In our day of rejecting God and His Word, we must be reminded that altering the design God built into the creation of everything from galaxies to viruses can have tremendous consequences. We have seen that in COVID, and again, we can learn a lesson from the DART experiment.

Once In a Blue Moon

You have probably heard the expression, “once in a blue moon.” People use that as a way of saying that something very rarely happens. For sky watchers, a blue moon has a different meaning. It refers to those times when a full moon occurs twice in the same month. That will happen tonight, Wednesday, August 30, 2023.

Although the “once in a blue moon” expression indicates something rare, astronomical blue moons are not all that rare. They occur on average four times per year, although they can happen as few as three times or as many as five times. The lunar cycle takes 29.5 days, so we usually have one full moon monthly. This year, we experienced a full moon on August 1, so we will see another one on August 31.

The “blue moon” title has nothing to do with its actual color. The Moon will appear white, yellow, or orange depending on its location and how much dust and other particles are in the air. If it is near the horizon, where its light has to travel through more of our atmospheric dust, it will appear white, yellow, or orange. High in the sky, it will look whiter unless there are perhaps pollutants, such as from wildfires.

In addition to being a blue moon, this full moon is also called a “super moon.” That is because it will be near its closest point to Earth. The Moon’s elliptical orbit averages nearly a quarter of a million miles from Earth. At the time of tonight’s full moon, it will be about 222,043 miles (357,344 km) from Earth. That means it will be the biggest and brightest full moon of 2023.

Despite people calling it a blue supermoon, it will not appear “blue,” and you may not think of it as incredibly “super.” It will be slightly bigger and brighter than other full moons this year, but you may not be extremely impressed. If you see it near the horizon, where it appears with buildings or trees, it will look more prominent compared to when you see it high in the empty sky. That is called the “moon illusion” and happens all the time, not just once in a blue moon.

So enjoy seeing tonight’s super blue moon, and thank God it’s there. Without it, we might not be here either. Our Moon is always “super,” as we have said many times. You can read more about that HERE, HERE, HERE, HERE, HERE, and HERE.

God’s Temple Is Sacred

“Do you not know that you are the temple of God and that God’s Spirit has His home in you? If anybody desecrates the temple of God, God will bring them to ruin, for God’s temple is sacred to Him, and that is what you are” (1 Corinthians 3:16 -17).

If you take the Bible seriously, you must understand that taking care of your body is essential to how you live. In this ministry, we have discouraged using alcohol, nicotine, marijuana, and all recreational drugs because Jesus and Bible passages like this one teach us that God’s temple is sacred.

How does God “bring to ruin” those who do not take care of their bodies? Like most actions of God, it is not by God playing Zeus and throwing a lightning bolt at an offender. God simply removes His protective hand from those who insist on desecrating His temple. When God removes His protective hand, what happens? Look at the evidence in the latest numbers from the Center for Disease Control.

In 2022, the CDC says that 109,680 Americans died of overdoses, over 60% from synthetic opioids. Marijuana use and vaping have climbed to the highest levels ever seen. In the past year, 44% of young adults used marijuana, up from 28% a decade ago. Over 10% of young adults use cannabis every day. Binge drinking for middle-aged adults hit 29% in 2022. As of 2021, 61.2 million Americans age 12 and older have used illicit drugs.

We can see the result of this abuse in the increase in emergency room visits, the rate of accidents, broken homes, and the collateral damage to families. The numbers from the National Center for Drug Abuse are staggering. It is difficult for those of us working with young people and people with mental issues to do any quantitative analysis. Suffice it to say that the number of cases coming to us is much higher than at any previous time.

Jesus said, “Beware of false prophets who come to you disguised as sheep but are really greedy wolves. By their fruits, you will know them…” Matthew 7:15-16. The message of the Bible as to how we should live gives beauty and purpose to life and provides the best measure of good health. God’s temple is sacred, but even people who reject the teachings of Christ can’t deny the destructive consequences of following the teachings of modern secular prophets.

The Tragic Fires of Lahaina

The tragic fires of Lahaina destroyed the train station — Lahaina train station before the fire

Those who have not been to Maui may be unable to comprehend the tragic fires of Lahaina and what happened there. I lectured on Maui several times, visited Lahaina, and even lived in the area for a short time in Kehei. Knowing the area, I can understand the conditions leading to the wildfire that destroyed the town and killed so many people.

Maui is a beautiful island. There are two huge mountains and two primary sections of the island. Haleakala is a popular tourist area with a road to Hana on the east side of a volcanic mountain where there are many gardens and lush vegetation. The other side is a barren area of relatively recent lava flows.

On the island’s northern side, a mountain area known as Kahakuloa has an observatory at the top. Lahaina is located on the west side of this mountain. I worked with a church on the east side of Haleakala, a wet area with lush vegetation. Between these two mountains is a relatively flat area with the villages of Waikapu and Pounene and the main shopping area for locals and tourists.

Unlike Haleakala, Kahakuloa has weathered igneous rock on its west side, which has led to soil capable of supporting crops, primarily sugar cane. When we were there, the growers used fire to remove the processed sugar cane. The area was very dry, with a vast cattle ranch and people living in open houses and sheds because rain was infrequent.

What we have described here is a classic example of a rain shadow. Moist air moves up the sides of the two mountains, and as it cools, it drops its water as rain. All the moisture is gone by the time it gets to the top of the mountains. As a result, very dry air goes over the mountain and cascades down the other side, creating desert-like conditions. This is not an area to attract tourists, but with irrigation, it’s a productive agricultural area.

A fire on the mountain’s east side would not spread since lush green trees and grass do not burn easily. On the mountain’s west side, any dead cane, grass, or bushes would be great tinder. People must plan for climate changes, avoiding towns where drought conditions can produce the tragic fires of Lahaina.

Agriculture must use places to plant crops based on understanding the movement of air and water. The tragic fires of Lahaina were not an act of God but the result of human mismanagement of what God has given us. The question is whether we will learn from our mistakes or repeat them.

The Problem of Homochirality

Can life arise spontaneously from non-living chemicals? Scientists have spent many hours and vast amounts of research money attempting to prove it can. One of the many challenges they must solve is the problem of homochirality.

All the large molecules required to make a living cell are composed of building blocks that have mirror images. When you look in a mirror, you see a reversed image of yourself. The right hand appears to be on the left and vice versa. The right- and left-hand analogy is used when referring to the building blocks of life. Those building blocks come in either right or left-handed forms. We call that handedness “chirality” from the Greek word for hand. Homochirality means having the same handedness.

Life almost exclusively uses only one chirality. The amino acids that make up proteins are left-handed. Scientists are uncertain why, but they have to accept the fact that to build the proteins that RNA and DNA molecules require for life, you must have only left-handed amino acids.

In nature, amino acids are not homochiral. They come in a distribution of about 50/50 left and right, creating the problem of homochirality. For amino acids to form the building blocks of life, they would have to be homochiral. Scientists have yet to find a way to make that happen, even in the laboratory. They aren’t even sure why life requires it since the chemical properties of mirror-imaged compounds are the same for all practical purposes.

The problem of homochirality is one of the many obstacles that prevent non-living chemicals from coming together to form life without intervention by an intelligent force. Even the intelligence of our best scientists has not overcome those obstacles. I saved an Associated Press news release from 2007 titled, “Scientists Believe Artificial Life Will Be Possible in 3 to 10 Years.” We are well past that goal, and I suspect they are not much closer today.

Purpose in the Evolutionary Process

Evolutionists such as Richard Dawkins tell us that life has no purpose and results from mindless, unguided evolution. That is the accepted doctrine of evolutionary biology. However, Dr. Gunter Bechly writing in the Evolution News website, reports on a review by Dr. Richard Buggs, giving some hope of at least one scientist finding purpose in the evolutionary process.

British plant biologist Richard Buggs wrote in Ecology & Evolution about a BBC science series called “Earth” in which the host, Dr. Chris Packham, made some very “non-Darwinian” statements suggesting purpose in the evolutionary process. Instead of viewing evolution as a natural process without purpose, Packham expresses it as an intentional process with direction.

Packham anthropomorphizes plants suggesting that they “have agency and intention.” He says they don’t “give up easily”; they “developed a new trick” and “were ready to start conquering the world.” He also points out something we have discussed on this site, that plants communicate with one another.

Packham finds purpose in the evolutionary process of plants. He suggests the greening of plants was not a purposeless, unintended process, but early photosynthesis was “something miraculous.” He describes the world as a “bountiful, blooming miracle” and the symbiosis between plants and fungi as “a match made in heaven.” The BBC promotes the series Packham hosts by saying, “Chris Packham tells the miraculous story of how plants turned Earth from a barren rock into a vibrant green world.”

In my graduate work at Notre Dame, an atheist taught our class on the historical development of planet Earth. He repeatedly pointed out that it takes enormous faith to believe that the complexities we see in Earth’s biological history leading to humans resulted from mindless chance processes. However, he justified his atheist faith by maintaining that given enough time, it could be possible.

Dr. Bechly concludes his article by saying he hopes this is “a new trend that would feel like a breath of fresh air amidst all the materialist and atheist propaganda in popular science media.” The current theories of how life developed on Earth by chance are so complicated and unlikely that evolution has become a faith for many. Finding purpose in the evolutionary process is a step toward recognizing that life is not an accident.

For over 50 years, we have said that evolution is a tool of God, designed to allow life to exist on a changing planet. God has indeed built into living things the capacity to change, so we have many varieties of dogs, cattle, grains, and fruit trees. Without this capacity for species to evolve and adapt, humans would have long ago run out of food.

With the verified climate changes in Earth’s history, many global mass extinctions would have occurred. There is a vast difference between the fact of evolution and the neo-Darwinian theories of naturalism and macro-evolution. Many conflicts would be eliminated if both sides could admit to that fact.
