Seaweed as a Food Source

Seaweed as a Food Source - Giant Kelp
Giant Kelp

God has given us a food source that so far humans have been unwilling to tap – seaweed. It is super fast growing, with some species like giant kelp growing 50 centimeters a day. Seaweed doesn’t need land or pesticides and doesn’t have to be watered. Furthermore, it is packed with protein, fiber, vitamins, minerals, and other nutrients. With over 800 million people starving worldwide, one answer might be seaweed as a food source.

Oceans cover roughly two-thirds of our planet, yet they contribute less than three percent of humans’ total food calories. Asian recipes have used seaweed for centuries, and its cultivation is limited mainly to Asia — large areas of the sea could be seaweed farms. There are 12,000 different types of seaweed, and humans have only learned how to cultivate fewer than 30.

Dried seaweed retains its nutrients and has a long shelf life, so it doesn’t have to be refrigerated or frozen. The reluctance to use seaweed as a food source has primarily come from misconceptions about it. Many of us have only seen water plants growing in a freshwater pond and have no idea what ocean-grown seaweed is like. In addition to food and the replacement of environmentally polluting agents, seaweed can be a significant carbon sink, absorbing massive amounts of carbon dioxide.

Seaweed can also be used as a natural fertilizer for land plants and as feed for animals. It can even be a cotton alternative in textiles and, in some cases, as a biodegradable replacement for plastics. Like most human problems, the solution is there, but we aren’t using all of the wealth of resources God has given us. One solution God has provided may be seaweed as a food source and more.

The Feel-Good Hormones

The Feel-Good Hormones

Hormones are chemical messengers that travel through our bloodstream. You can describe them as signaling molecules that work to set things in motion. The name comes from a Greek word meaning “setting in motion.” Hormones are produced in various areas of our bodies and are sent through the bloodstream to signal some action or response. Good health requires a balance of hormones, and proper diet, exercise, and rest help to keep them in balance. The feel-good hormones are four classes of hormones that, as you might guess, do things that make us feel good.

ENDORPHINS- Endorphins are the body’s natural painkillers. The pituitary gland, located at the base of the brain, synthesizes and stores them. Endorphins help to mask pain, reduce stress, and improve mood. When we push through a painful task or strenuous exercise, endorphins are there to help us. 

DOPAMINE- Two areas of the brain produce dopamine, and you can think of this hormone as the brain’s reward system. Exercise, eating a food we like, or accomplishing a task can cause the brain to release dopamine, giving us a pleasurable feeling. The use of some drugs and alcohol can release a flood of dopamine, giving us a sense of euphoria, a “high.” But coming down from that high can lead to depression and a desire for more of the drugs. Normal activities or exercise stimulate dopamine more slowly, and the effect of the hormone remains longer. Good stewardship of our bodies and health calls for avoiding harmful drugs and alcohol.

OXYTOCIN- Some people call this feel-good hormone the love hormone. Touching, hugging, or sexual activity can trigger the release of oxytocin. The brain’s hypothalamus produces it, and the pituitary gland releases it into the bloodstream. Oxytocin can help improve social interactions and give us a desire to develop stronger connections with others.

SEROTONIN- Serotonin is a natural mood booster, and depression can result from a low level of this hormone. Serotonin performs many functions and is produced by the central nervous system in various areas of the body. Serotonin improves memory and learning and promotes relaxation. Exercise, as well as exposure to sunshine and the outdoors, can increase the production of serotonin. Meditation and quietness in prayer can also reward us with this mood-boosting hormone.

The feel-good hormones are part of good health, and a healthy lifestyle boosts them. However, too much of a good thing too quickly is not healthy. Alcohol and drugs can give us a high but only lead to a letdown. A healthy lifestyle involves proper diet, exercise, rest, prayer, meditation, thankfulness, and balanced relationships with others. Incorporating those things into our lives is the best way to enjoy the blessings God has for us.

Biological Complexity in Living Organisms

Biological Complexity in Living Organisms compares to Moore's Law by Gordon Moore
Gordon Moore – The background is a magnified diagram of the complex layout of a microchip.

Those who advocate for naturalistic evolution have a problem. Well, they have more than one, but this one is a math problem. In a publication on the National Institutes of Health’s Pub Med website, Alexei A. Sharov presents a dilemma for evolutionists. Simply stated, the size of the genome indicates biological complexity in living organisms, while macro-evolution requires exponential growth to achieve that biological complexity.

Perhaps this will be easier to understand if we relate it to Moore’s Law in semiconductor technology. In 1965, Gordon Moore of Fairchild Semiconductors and Intel projected that the number of components in each integrated circuit would double yearly. In 1975, the prediction was revised to every two years. It took on the quality of a “law” as the semiconductor industry used it as their target for planning production. Moore’s Law has led to technological changes that produced economic growth and social change. The point is that doubling the complexity of electronic technology means a logarithmic increase in versatility, as we have seen over the years.

Alexei Sharov applied that principle to evolution based on the exponential growth in biological complexity. Using the exponential increase in biological complexity in living organisms as a guide, it is possible to go backward in evolutionary time to see when life began. If the exponential hypothesis is true, tracing back in time, the origin of life would have been ten billion years ago. That is how long it would take for the genome to evolve to its present complexity in mammals. No evolutionist or other scientist believes our planet is that old. That presents a math problem for naturalistic evolution.

So, what do Sharov and others propose as the solution? They call it “panspermia,” meaning that life came to Earth from outer space. Nobel Prize winners Fred Hoyle and Francis Crick were advocates for panspermia. However, most evolutionary scientists reject it. Perhaps there is a better way to explain the fact that naturalistic evolution does not fit into Earth’s timeline. The solution, soundly rejected by Hoyle and Crick, is the idea of a Creator outside of time and space who designed the universe and life and put us on this planet for a purpose.

Afraid of the Facts

Afraid of the Facts - John Adams wasn't
President John Adams

We should never be afraid of the facts when they are accurately presented. U.S. President John Adams said, “Facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passion, they cannot alter the state of facts and evidence.”

Last week, we looked at James Tour’s challenge to the leading origin-of-life scientists. None of them were willing to address even one of the five roadblocks to abiogenesis that he presented. The fact is that the study of abiogenesis, the origin of life from non-living matter, has progressed very little in the last 70 years. Science has found many barriers to abiogenesis since the Miller-Urey experiment of the early 1950s.

Quora is a social media question-and-answer website where people post questions and others respond with answers. A recent questioner asked, “Are scientists terrified of abiogenesis?” A person who said he was “45 years a physician” answered that he was not afraid of abiogenesis. Part of the response from the “physician” was:

“Abiogenesis is a process that occurred at least once in the history of the earth, and that single event (or handful of events) may have left no traces at all. The steps in abiogenesis were probably a series of unknown physical and chemical steps. So, the process may never be known.”

Saying that “unknown physical and chemical steps” in a “process may never be known” is a vague answer. He seems to be saying, “I’m not going to worry about that because it scares me.” As I said, people should never be afraid of the facts.

Genesis chapter one uses the Hebrew word “bara,” which is always used to describe something that only God can do. Verse one describes God creating the heavens and Earth out of nothing. Verse 21 uses that word again to describe the creation of the first animal life. Between those verses, the term “made” (Hebrew “asah”) or the words “let there be” describe God’s work.

Science has made significant progress in understanding the processes described by “made” and “let there be.” In some cases, scientists have even duplicated those processes in laboratories or particle accelerators. However, understanding how God created everything from nothing or life from non-living matter is beyond what science has accomplished or perhaps will ever understand. Christians should never be afraid of the facts because they point to a creator God.

World of Life Beneath the Soil

World of Life Beneath the Soil - Naked Mole-Rat
Naked Mole-Rat

An unknown world of life lurks beneath our feet, and we should be thankful that it does. A research report in the Proceedings of the National Academy of Sciences (PNAS) says that approximately 59% of all living species on Earth live in the soil. Because there are so many organisms living there and they are generally out of sight, scientists don’t know how many species exist in the world of life beneath the soil.

According to the report by Diana Wall of Colorado State University, Fort Collins, soil organisms support life above the soil in many ways. They make it possible for us to grow food, and they break down organic waste. We often think of earthworms, but there are also many smaller worm species. We seldom see various insects that spend their lives in the soil. However, we do see insects that live much of their lives under the ground as well as above. Those include ants, springtails, woodlice, and millipedes. We often think of some animals that live in the soil as pests, such as termites and nematodes. However, they serve the purpose of breaking down organic materials, helping to keep the world from filling up with waste.

Plants also live in the world of life beneath the soil. For example, fungi do not use photosynthesis like green plants, so they can survive in the darkness. Subterranean life forms include the least familiar amphibians, the caecilians, whose name means “blind ones.” Naked mole-rats live underground, and many other mammals spend at least part of their lives in subterranean darkness.

According to the report in PNAS, “soil is the most biodiverse singular habitat.” We don’t often think of the world of life beneath the soil, but we should thank God that He thought of it. Subterranean life makes it possible for life above ground to thrive and prosper. We see this incredible web of life as evidence of design.

James Tour Challenge

James Tour Challenge

How did non-living chemicals become living plants and animals? Origin of life research has been the focus of countless hours and vast expenditures by expert scientists for the last 70-plus years. The results have been, well, unremarkable. Chemist Dr. James Tour of Rice University issued a 60-day challenge. The James Tour challenge to the leading origin-of-life researchers called for them to show what progress they have made in 70 years.

Dr. Tour points out that there are five major hurdles that the origin-of-life scientists must clear. They are the fundamental problems that stand in the way of life originating from non-life (abiogenesis). In simplified form, they are:

Linking amino acids into chains
Linking nucleotides into RNA molecules
Linking simple sugars into chains
The origin of biological information
The assembly of all components into a cell

YouTubers are claiming that scientists have completely solved these obstacles to abiogenesis. If that is true, Tour challenged the leading origin-of-life researchers to verify and explain it. The James Tour challenge gave them 60 days to put up their evidence. Dr. Tour said if they could show that they have solved even one of those problems, he would shut up about the issue.

The James Tour 60-day challenge expired at the end of October 2023. Not one scientist could meet his challenge. In other words, in 70 years of research, no progress has been made on any of the major roadblocks to non-living matter becoming a primitive living cell.

If brilliant scientists with the best equipment and modern laboratories ever manage to produce life from basic elements, what will they prove? They will not show that life can originate by unguided accidents. They will have demonstrated that an intelligent being can create life from non-living matter. That is what the Bible has said for thousands of years.

Witch Hazel Howitzer

Witch Hazel Howitzer
Witch Hazel Flowers

Plants use an incredible variety of methods to distribute their seeds. Witch hazel shrubs use one of the most impressive methods. Rather than relying on birds, animals, wind, or flowing water, witch hazels shoot their seeds. The system is so well-designed that in half a millisecond, the seeds shoot out of their pod at speeds up to 30 feet per second. This method had been described as a witch hazel howitzer.

The U.S. National Science Foundation supported researchers at Duke University in a study of the incredible method witch hazels use to scatter their seeds. The researchers studied various species of witch hazels, including those that have seeds lighter than a grain of rice and others ten times that weight. Their research shows that all species they studied sent seeds flying at the same velocities regardless of the seed’s mass.

The way this system works is that the woody seed pod dries out and deforms in a way that squeezes the seeds. The pressure builds until it pops, sending the seed flying. The director of the study, Justin Jorge, says it is like squeezing a watermelon seed between your fingers until it shoots out. The force built up by the witch hazel is enough to send seeds over large distances, allowing this plant to reproduce in a forest without the help of wind, birds, or running water.

We see design in the witch hazel’s seed dispersion method, and it reminds us of Romans 1:20, which says we can know there is a God by looking at the things He has made. We see that evidence in the vast variety of ways plants reproduce. We see plant seeds transported by wind. Some plants produce a fruit that birds or land animals eat, but the seeds pass unharmed through the animal’s digestive system. Some plants have seeds that stick to the fur of animals, and some animals intentionally bury seeds. Others attach a small nugget of nourishment for ants. The ants eat the food and discard the seeds far from where they found them. When none of these options are available, God has built plants that propel their seeds over a wide area, like a witch hazel howitzer.

The First Month of Human Development

The First Month of Human Development Begins with Fertilization

When the sperm meets the egg, a human cell is produced. From this single cell, a human body is built, containing over 30 trillion cells. How does that happen? Science really has no answer to that question. Dr. Jacob Hanna at the Weizmann Institute of Science refers to this stage of human development as a “black box.” Most of the research on embryo development has been done on mice, rabbits, chickens, and frogs. What happens during the first month of human development remains largely unknown.

Understanding what goes on during the first month of human development would help in dealing with miscarriages, congenital birth defects, and the side effects of medications taken during pregnancy. Dr. Hanna and other researchers have built a group of cells that act like an embryo but can’t grow into a fetus. This group contains the cell types that are essential for an embryo’s development, including the placenta, yolk sac, and outer membrane. This is all before any organs are formed, and takes about eight days.

Dr. Hanna does his research without using fertilized eggs or anything derived from aborted babies. Scientists are already using these stem cell models taken from adult skin cells. This work could have addressed some problems of the past, such as the drug thalidomide, which was used as a treatment for morning sickness and was found to cause birth defects.

The complexity of the changes taking place during the first month of human development speaks of the wisdom and design that has produced all humans. We are very different from the animals that make up the world around us. The difference becomes evident as we study the development of a fetus from the single cell that started the process.

Many years ago, the writer of Psalms 139:13-14 reflected on this as he said, “For you created my inmost being: you knit me together in my mother’s womb. I will praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well.”

Neanderthals and the Bible

Neanderthals and the Bible
Wax figure of Neanderthal man in Field Museum of Natural History, Chicago

In 1856, workers in Neander Valley near Dusseldorf, Germany, discovered a cave containing human bones that were different from modern humans. Scientists gave those bones the name Neanderthal, which means “Valley of the New Man.” We have written about this before (such as HERE, HERE, and HERE), but how can we reconcile Neanderthals and the Bible?

Since that first discovery, anthropologists have found Neanderthal remains throughout Europe and elsewhere. Neanderthals had large brains, thick bones, and muscle attachments, indicating high strength. The age of these specimens is much greater than any written human communication. They lived a nomadic lifestyle and dwelled in caves and natural shelters. They did not have cities or build sophisticated structures, but recent studies show intelligent behavior, including mastering fire for cooking, controlling animals, and providing warmth.

Genetic studies show that modern humans had Neanderthal ancestors. Some writers claim that Neanderthals were humans physically but had no soul and, thus, no spiritual awareness. That raises the question of how Neanderthals connect with Adam in Genesis 1 and 2. Those who promote theistic evolution say that ape-like hominoids evolved. Then, when these individuals reached a certain level, God infused them with a soul and called them “Adam,” Hebrew for “of the ground.” Some claim that Cain encountered Neanderthals in the area that Cain was banished to in Genesis 4:14 and following.

The point is that rather than deny that Neanderthals existed, we need to realize that there are many possible ways to reconcile Neanderthals and the Bible account of Adam and Eve. As scientists make more discoveries, the picture may become more evident. Meanwhile, we know the biblical account is valid and not at odds with findings about human history.

Transplanting Animal Organs into Humans

Transplanting Animal Organs into Humans

On September 20, 2023, Lawrence Faucette had a pig’s heart transplanted into his body to replace his own heart, which was in total failure. Xenotransplants, transplanting animal organs into humans, have been tried in the past, but the patient’s immune system destroyed the transplanted organ. Faucette’s animal heart came from a pig that was genetically modified to make it more human-like. After a month, there has been no sign of rejection, and Faucette is in physical therapy. The medical science community is interested in xenotransplants because there is a massive shortage of human organs for transplantation.

Many people have questioned the religious implications of xenotransplants. Various Bible passages speak of the human heart but not the physical organ. The Old Testament uses the Hebrew word for “heart” 851 times, primarily referring to the mind of an individual. There are a few cases, like Absalom in 2 Samuel 18:14, Nabal in 1 Samuel 25:37, and Joram in 2 Kings 9:24, where the physical heart is intended. In the New Testament, when Jesus talks about the “pure in heart” in Mathew 5:8 or refers to hard hearts, as in Mark 3:5, these are clearly not references to the physical heart.

The bottom line is that God is not primarily concerned with
the physical organ but with our thinking, attitude, compassion, and capacity to love and serve. What happens to a person’s body is that it will eventually return to the Earth from which it came. Abraham said in Genesis 18:27, “I am but dust and ashes.” Solomon wrote in Ecclesiastes 12:7, “Then shall the dust return to the earth as it was: and the spirit shall return to God who gave it.” The psalmist wrote, “we are dust” (Psalms 103:14), and we “die and return to the dust “(Psalms 104:29).

Doctors have used valves from pig hearts for a long time, with great benefits for those who receive them. Understanding God’s design and creative wisdom opens the door for transplanting animal organs into humans, providing ways to make a human’s short tenure on Earth more pleasant. However, it is ultimately our soul and relationship with God that is of primary concern. Jesus made that abundantly clear when He said, “Do not fear those who kill the body but are not able to kill the soul: but rather fear him which is able to destroy both body and soul in hell” (Matthew 10:28).
