Seaweed as a Food Source

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

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.

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.

The First Month of Human Development

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

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

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. (Update: Unfortunately, Mr. Faucette passed away on October 30, 2023.)

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).

Is Moderate Drinking Good for You?

Have you seen media reports claiming that alcohol is good for you? It turns out that the studies that led to those headlines were severely distorted by poor sampling. Those studies linked all nondrinkers together and called them all “abstainers.” Some of them were recovered alcoholics who had quit drinking. Others were non-drinking substance abusers or those suffering from chronic illnesses. Meanwhile, the “moderate drinkers” in the study could include those who ate healthy and exercised. More balanced modern studies answer “Is moderate drinking good for you?” with a “NO!”

Based on more non-biased studies, by 2022, the World Heart Federation stated that alcohol did not protect people from cardiovascular diseases. The World Health Organization (WHO) has now stated that any amount of alcohol is dangerous. U.S. and Canadian authorities have lowered their definitions of “moderate-risk drinking.” A growing body of research says that any amount of alcohol raises the chance of premature death from various causes. Here is what is now known:

Half of all cases of liver disease are attributed to drinking.

Alcohol is a potent carcinogen because it breaks down in the body to form a compound called acetaldehyde, which damages DNA.

Fifteen percent of breast cancers are linked to alcohol.

In Europe, 50% of all cancers linked to alcohol are caused by “light” or “moderate” consumption.

The distressing thing about this is that young people are bombarded with messages and music glamorizing drinking. Television shows encourage drinking by showing a glamorous picture of people drinking alcohol. The health damage and risks from alcohol consumption are not presented to young people in any educationally sound manner.

Biblical teaching tells us that the body is the temple of God’s Spirit and must be cared for and protected (1 Corinthians 3:16). The Church should lead in education, especially with teens and young adults. So far, that has not happened, and the whole basis for not drinking is frequently lost in discussions about “moderation.” Is moderate drinking good for you? No, and beyond that, “There is no safe amount that does not affect health” (WHO).

Otzi Had Dark Skin

“Otzi” was the name given to a frozen mummy found on the border between Austria and Italy in 1991. The mummy, also known as “the iceman,” was in such good condition that researchers could complete a DNA analysis of his genome in 2012. Recently, more advanced studies of that DNA show that the earlier sample was contaminated by modern DNA, and Otzi had dark skin.

The Planck Institute for Evolutionary Anthropology in Leipzig, Germany, compiled a new genome for Otzi. Johannes Krause, writing for the Institute in the August 16, 2023, issue of “Cell Genomics,” reported that there is no connection between Otzi and modern residents of Austria or Italy. The revised genome shows that Otzi had dark skin and was related to Neolithic farmers.

Modern genomes of ancient humans show that dark skin has been the norm for humans until relatively recently in human history. Light skin tones only appeared in the genomes 3 to 4,000 years ago, showing once again the foolishness of racism. The ancient humans described in the Old Testament were undoubtedly dark-skinned.

You cannot use the Bible to justify racial prejudice. The statement that God “has made of one blood all nations of men to dwell upon the face of the earth” (Acts 17:26) is absolutely true. The name “Eve” in the Hebrew of Genesis means “life-giving,” and she would have had dark skin. Genetic studies have shown that all humans have a common DNA fragment indicating a common origin. Those who have viewed Otzi as proof that ancient humans were Caucasians have no scientific support for that claim and now have to admit that Otzi had dark skin.

There is too much scientific support for the biblical account of early humans to write it off as a fantasy or a myth. Science and the Christian faith are symbiotic – they support each other. Let us put racial prejudice to rest and embrace the claim of Galatians 3:28 that we “are all one.”

Children Seeking Gender Reassignment

One of the most serious problems facing parents, schools, and churches is what to do with children seeking gender reassignment. This has become a political football, a money-making enterprise, a lawyer’s paradise, and a parent’s nightmare. Teachers deal with kids who are wearing several names and pronouns depending on what their day-to-day feelings dictate.

Those who promote gender reassignment confront unwilling parents with questions such as, “Do you want a dead daughter or a live son?” Studies show that the number of teenage girls with gender dysphoria has risen by 5,000% in seven years. This has become a massive money-maker for various groups, from Planned Parenthood to doctors and hospitals.

A British book by Hannah Barnes titled Time to Think provides a wealth of data on this issue in Europe, and it’s getting some attention in the United States. Here are some interesting facts from Barnes’ book:

*A large number of children seeking gender reassignment had other psychological issues. In one study, 97.5% had one or more disturbing issues, including having been in foster care, endured parental divorce or death, been abused, or endured personal trauma. Seventy percent had five or more difficulties of this kind. Twenty-five percent had histories of self-harm.

*Information given to children about sex change has been generally inaccurate. Kids have been told that puberty blockers would not affect bones, muscles, and brains or that effects were completely reversible. None of those assertions are true.

*Studies done since 2011 on the effects of puberty blockers in England showed no improvement in patients’ mental state. Sweden, Norway, and Finland have severely curtailed the use of puberty blockers and cross-sex hormones, saying that the risks outweigh the benefits.

There is a strong name-calling campaign against anyone who questions sex change. “Transphobic” has joined “homophobic” in the vocabulary of promoters of sex-change medications and surgical procedures. We are facing an uphill battle because greed and money are involved. The disintegration of God’s plan for the family and the selfishness and greed of adults have resulted in the use of children to satisfy adult issues. Working on children’s psychological problems is far better than throwing drugs and surgery at the needs of disturbed kids.

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.
