The Homochirality of Organic Molecules

Yesterday, we discussed the chirality, or handedness, of molecules, especially amino acids and proteins. The homochirality of organic molecules refers to their requirement for the same handedness, a mystery that has puzzled scientists since 1848, when Louis Pasteur first observed that some life-essential molecules had mirror-image forms. Amino acids used by living cells and the proteins they build have left-handed chirality, while DNA, RNA, and the sugars forming their building blocks are all right-handed. These facts raise a question for those who believe life arose spontaneously.

Left-handed proteins and right-handed DNA are found in all living organisms. The spiral structure of DNA needs to twist in a specific direction to function properly, but what caused the right-handed sugar molecules to come together? When half of all amino acid molecules in nature exhibit right chirality and the other half left, what force could have gathered only the left-handed ones to form the first proteins?

Scientists have speculated that cosmic rays or polarized light might have triggered this process. However, even if such forces created an initial bias for the same-handedness, they could not sustain and amplify it enough to produce a significant number of homochiral molecules to form the first living cells. In 1999, researchers proposed that electron spin created magnetism, causing left-handed peptides (short chains of amino acids) to bind to magnetic surfaces like magnetite. But this still did not explain how the homochirality of organic molecules could be amplified sufficiently to generate living cells.

Some scientists consider RNA to be the key to the origin of life. In 2009, a group of researchers studying RNA molecules suggested that a crystal called RAO could react to produce two of RNA’s four nucleotides. In 2023, other researchers used magnetism to produce RAO crystals with homochirality. However, this process required a magnetic field 6,500 times stronger than Earth’s magnetic field. Additionally, RAO has only been shown to produce two of RNA’s four nucleotides, still falling short of generating the complete homochirality of molecules needed for life.

As 2024 ended, NASA-funded research identified a problem with the so-called “RNA world” hypothesis. Simulating early Earth conditions, they found that RNA did not show a chemical bias toward selecting homochiral amino acids. The current thinking is that the homochirality of organic molecules “could have emerged through later evolutionary pressures.” In other words, we have the “evolution-of-the-gaps” theory because, of course, evolution can do anything you can imagine.

Currently, NASA scientists are analyzing samples brought back from asteroid Bennu, hoping that molecular evidence from meteorites and asteroids will demonstrate that the building blocks for life came from beyond Earth. I suspect that the force responsible for bringing life to Earth did originate outside our planet, and even beyond the universe.

Left-Handedness of Proteins and Amino Acids

About 9.2 percent of people are left-handed. In other words, less than 10 percent of humans exhibit left-handedness. However, the proteins in living organisms are 100 percent left-handed. I know proteins don’t have hands, but using the term “handedness” helps to explain how proteins are structured. Proteins are made from amino acids, which fold into left-handed shapes that enable their functions in living beings. These proteins are composed of amino acids, which are also left-handed.

This handedness is more accurately called “chirality.” There are over 500 different amino acids, and they exhibit both left and right chirality. However , only 22 of them are used to make proteins, and their chirality is all left-handed. This creates a mystery. If amino acids existed on early Earth in equal amounts of right- and left-handed forms, and life requires only left chirality, how could life have formed spontaneously? Some thus-far unexplained force would have to select only left-handed amino acids to come together to get life started. Robert F. Service, writing on science. org, called this “an enduring mystery.”

Scientists have proposed several ideas to explain why proteins are left-handed. Some suggest meteorites delivered left-handed amino acids to early Earth. It appears that meteorites are rich in these amino acids, likely due to exposure to polarized light. Another hypothesis is that magnetic fields on early Earth twisted the biomolecules. Robert Service asks, “But even if some external force imparted an initial bias, what propagated it?”

Gerald Joyce, a chemist specializing in the origins of life and president of the Salk Institute for Biological Studies, said, “Perhaps it was just a statistical coin flip that caused an original bias toward building blocks of one-handedness to form. But once that coin flipped, it caused other coins to flip.” Those of us who believe in a Creator are often accused of using a “God-of-the-gaps” explanation for life’s mysteries. To me, this explanation for the left-handedness of proteins sounds like a “coin-flip-of-the-gaps.”

Axolotls, or Mexican Salamanders

People often call them Mexican walking fish, but they are not fish. They are amphibians, specifically salamanders. Axolotls (Ambystoma mexicanum) or Mexican salamanders look like a fish because it never fully leaves its larval stage.

Unlike other salamanders and frogs, axolotls do not go through metamorphosis. When they become adults, they still look like tadpoles. They develop tiny legs but keep their gills instead of growing lungs and moving to land. The external gills and caudal fin, which are usually only found on salamander larvae, give axolotls a fish-like appearance.

Genetic differences lead to four color variations, from black or olive to pale pink or gold. They eat insects, worms, and small fish by sucking food into their mouths like a vacuum cleaner. In the wild, they are critically threatened and close to extinction because their last native habitat, Lake Xochimilco, is being overtaken by urban growth from Mexico City. However, many of these salamanders are bred in captivity as exotic pets and for research.

Axolotls are valuable for studying heart and nerve functions. They have an incredible ability to heal themselves, capable of regenerating severed limbs and some internal organs. Their injuries heal without leaving scars. Axolotls can also accept transplants of organs, eyes, or even brain parts without rejection issues.

Scientists study axolotls to discover new secrets of healing. God has given us many resources in the natural world and the ability to learn from them. As we have said many times, science and faith are friends, not enemies.

Natural Environment and Pain Relief

Experience has shown that spending time outdoors in a natural environment can help relieve stress and promote relaxation. A new study indicates that there is also a connection between the natural environment and pain relief. It may be surprising that enjoying the beauty and peacefulness of God’s creation can actually reduce the sensation of pain.

To create a controlled laboratory test, the researchers used images and sounds. For a natural setting, the test subjects were exposed to images of a lake surrounded by trees and hills, accompanied by birdsongs and wave sounds. For an urban setting, the subjects viewed an urban lake surrounded by tall buildings with traffic and construction sounds. The third group saw an office scene with computer and fan sounds. The researchers performed MRI scans on the brains of dozens of test subjects while they were exposed to these fake laboratory environments.

For the test, the subjects were exposed to shocks of increasing intensity while the researchers monitored their MRIs. The test subjects exposed to the urban and indoor environments showed the expected brain activity when sensing pain. However, the areas of the brain that receive pain stimulus (nociception in medical terms) were dulled when viewing the natural environment. You could call it “natural” pain relief. According to Maximilian Steininger, who authored the study, they found that the pain relief was not just a placebo effect. It really worked.

The results of this study could be helpful for healthcare facilities and hospitals. Perhaps that’s why my dentist has a nature scene picture on the ceiling above the patient’s chair. Perhaps he should add some natural sound effects. However, creating a natural scene in the lab (or dentist’s office) cannot compare with the real thing. When feeling pain (or stress), getting outside to enjoy God’s creation might be the best medicine. A real connection exists between the natural environment and pain relief. Enjoying God’s creation also inspires us to worship and thank Him for the beauty we enjoy in the outdoors.

Shocking Amount of Food Wasted

God has given us more than enough food for every man, woman, and child on this planet. Jesus told His followers to use what God has given. In Matthew 25:34-46, Jesus tells us what His disciples need to do. Providing food, water, and clothing are at the top of His list. Those who don’t provide these things for those in need are condemned. The problem is the shocking amount of food wasted.

I am directly involved nationally with programs that provide for those who are in need. Locally, I am involved with a program called “Feeding America,” and our small congregation provides food for over 100 people every month. Similar programs, both nationally and locally, are conducted by people who call themselves “Christians.” There are no atheist programs anywhere doing this.

So, if all this is going on, why is there a shortage of food worldwide? In the United States, one in every five kids doesn’t have enough to eat in spite of the fact that 530,000 metric tons of food are thrown out. The shocking amount of food wasted in schools is an example. Data from audits of schools in Miami and Orlando, Florida, show that the food thrown out amounts to 1.06 billion pounds from school cafeterias every year. These cafeterias also waste 20.9 billion gallons of water annually, resulting in a loss of $1.7 billion. Sixty percent of cafeteria waste is fruit and unopened milk.

This is just one case in two large Florida cities. Can you imagine how much waste there is nationally? As America continues to reject God and Christianity, we can expect this problem to get worse. In the biblical record, we see God telling humans to use what He has already given them. God doesn’t condone waste and will not provide for us what we can provide for ourselves. We see passages like Proverbs 6:6-11 where people who won’t work are called “sluggards” who will end up in poverty. Christians must lead the way by not wasting what God has given us.

Microbiomes in Living Tree Trunks

A study of microbiomes in living tree trunks reveals that the woody tissues of trees contain a trillion microbial cells in addition to the actual tree cells. This includes single-celled bacteria and archaea, which are specialized for different parts of the tree and for various tree species.

The research team, led by Jonathan Gewirtzman of Yale University, studied more than 150 trees across 16 species in the northeastern United States. The trees examined included red maples, black birches, and white ashes. They discovered that microbes can live in both the outer sapwood and the inner heartwood, with each region hosting its own microbiome. Sapwood is mainly inhabited by microbes that require oxygen, while heartwood contains anaerobic microbes.

The study shows that microbiomes in living tree trunks vary from species to species. But how do these microbes get inside the trees? It might happen through wounds or openings, or they could be passed through the tree’s seeds. Perhaps, there is another route scientists have yet to discover. Regardless of the method, Gewirtzman explains, “What looks like one thing is a trillion-in-one organisms living together.”

When you see a tree, you might not realize how intricate its design is. Genesis 1:11-12 states, “Then God said, ‘Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds,’ and it was so. The land produced vegetation: plants bearing seeds according to their kinds and trees bearing fruit with seeds in it according to their kinds.”

Like many other living things, scientists are only beginning to understand the complexity of microbiomes in living tree trunks. We can recognize that there is a God through the things He has made, including trees. (See Romans 1:20.)

Why Are There So Many Species?

How many species of living things exist? So far, scientists have identified, classified, and named 1.2 million species, according to worldatlas.com. The same source states there are about 8.7 million species on Earth. Nobody knows for certain, but other estimates—excluding viruses and bacteria—range from 10 million to 100 million species. Why are there so many species of living things?

How quickly are scientists discovering and describing new species? According to worldatlas.com, they identify and assign genus and species names to 15,000 to 18,000 new species each year. At that rate, if we assume 1.2 million have already been named and there are 10 million in total, the task will take over 500 years, but that’s a conservative estimate. Clearly, biologists still have a lot of work ahead.

There are between six and seven thousand known mammal species according to ourworldindata.org, . But the insect world surpasses that number. For example, beetle species alone number between 350,000 and 400,000. Each year, biologists identify most of the “new species” from museum specimens discovered earlier but not carefully studied. Some species in the wild are facing extinction, and some specimens in museums may already be extinct.

We may ask, “Why are there so many species?” God created diverse kinds of living things and endowed them with the ability to adapt to different environments. Each new species fills a niche in the incredible diversity of animal and plant life that makes our existence possible.

We have previously described the various taxonomic classifications used to categorize living things. (You can read that HERE.) “Species” is the lowest and most specific taxonomic category used by scientists to describe life forms. God created humans with an insatiable curiosity and an amazing ability to organize and categorize information. Then, He gave us plenty of life forms to study. We believe that we can learn more about God as we explore His creations. (Romans 1:20)

Frequently Quoted “Scriptures” Not Found in the Bible

“God helps those who help themselves.” That was a favorite “scripture” of my father, and he quoted it many times. The problem is that it is merely one of the frequently quoted “scriptures” not found in the Bible. In fact, it contradicts a very important Bible message. We cannot save ourselves. We cannot be good enough to deserve a heavenly reward. Trying to do so only shows a lack of faith in what Jesus has already done for us. See Romans 3:23, 6:23, and Ephesians 2:8.

“Cleanliness is next to Godliness.” Perhaps a parent may quote this “scripture’ to a child who needs to wash, but you won’t find this in the Bible either. In fact, the enemies of Jesus criticized his disciples because they did not ceremoniously wash their hands before eating. Jesus responded very directly about what real cleanliness is. Read it in Matthew 15:1-20.

Another of these frequently quoted “scriptures” not found in the Bible is, “God moves in mysterious ways.” You won’t find those words in the Bible, but in a hymn written by English poet William Cowper in 1773. It is based on Psalms 77:16-19. The first verse of the hymn says,

God moves in a mysterious way,

His wonders to perform.

He plants his footsteps in the sea

And rides upon the storm.

Deep in the dark and hidden mines,

With never-failing skill,

He fashions all his bright designs

And works his sov’reign will.

Yes, God’s ways are mysterious, but He created humans with curiosity and a desire to discover how God does things. Science has unlocked many of the mysteries of creation, but we have only scratched the surface. A leading American computational, physical, and theoretical chemist, Henry F. Shaefer III, once remarked, “The significance and joy in my science comes in the occasional moments of discovering something new and saying to myself, ‘So that’s how God did it!’ My goal is to understand a little corner of God’s
plan.” (U.S. News & World Report, Dec. 23, 1991, cited by Dr. John Oakes).

Frequently quoted “scriptures” not found in the Bible may not be truthful. What we need to realize is that the Bible tells us everything we need to know to be saved. However, it does not tell us everything that can satisfy our curiosity. That is where science fills the gap. The point is that true scientific facts and a correct understanding of the Bible must be in agreement because they both come from the same source—God.

Only a Mind Can Create a Mind

Did the universe originate with matter or with a Mind? If matter was the starting point for all things, then we are simply matter. In that case, how can we have a mind? Are our minds just collections of cells formed from molecules that consist of atoms, which are made up of subatomic particles? Could unguided matter create our minds? Do we merely imagine that we have minds?

It seems more reasonable that a Mind was the starting point for all things. In that case, the Mind initiated the matter that formed the entire cosmos, all living things, and us. That Mind gave us minds, because only a Mind can create a mind.

The human mind has two parts working together. The physical part is what we call the brain. Materialists try to tell us that the brain is all there is. The brain handles material processes, including sensory and motor functions. It also influences emotions and memory. The other part, the soul, is not made of material substance. The soul performs abstract reasoning, makes moral choices, and exhibits free will. It is what makes us different from all other animals.

This non-material part of our mind works in conjunction with the physical brain. The brain controls our physical movements but deciding what to do is primarily under the influence of the soul. Reasoning and decision-making are activities of the soul, but damage to the brain can severely affect our ability to reason and make moral choices.

The physical and spiritual aspects of our minds must work together to make us fully functioning humans. For that reason, a person who experiences brain damage from stroke, brain cancer, severe brain injury, Alzheimer’s, or other causes struggles with abstract reasoning and decision-making. Dementia also results in loss of memory, sensory awareness, and motor skills, and it affects our emotions. However, physical factors such as fatigue and illness can also impact those things.

It’s essential to understand that despite physical impairments, whether temporary or permanent, we remain the same person with the same soul. For those suffering from dementia, regardless of its cause, loved ones need to realize that the soul, the spiritual part of that person, is still present. Malfunction of the brain makes the person seem very different, but the person’s soul is still present. We are all made in the image of God, who is a spirit (John 4:24), not physical. We are spirits functioning within a physical body. In this life, a damaged brain can limit the functioning of a person’s soul. However, we can thank God that the soul is freed from the brain at the moment of death, and those who have accepted the salvation Jesus offers will spend a blissful eternity with Him.

Global Warming in the Past

We all need to be concerned about the impact of human activities on climate change, but the media hype suggesting that global warming is something new is simply not true. Science News magazine reported data on global warming in the past, going back to the Paleozoic era over 485 million years ago.

The data show that temperatures reached nearly 95 degrees Fahrenheit (35 degrees Celsius) three different times in Earth’s history. The time of the coolest temperatures is the period in which we are living. Earth cooled about three million years ago, reaching 53.6 degrees Fahrenheit (12 degrees Celsius). According to NASA, the present average global surface temperature is 59 degrees Fahrenheit (15 degrees Celsius). It appears that our planet is heading into a warm cycle, which humans contribute to, but they are not the only cause.

The media and politicians sometimes present an alarmist view of the future to attract more attention. There has been global warming in the past, and while humans will be affected by future climate change, there are many contributing factors.
