Bacteria Working Together

Bacteria are single-cell microorganisms that we do not think of as having social behavior. However, scientists are studying Myxococcus xanthus bacteria working together. They are rod-shaped bacteria that live in the soil and organize into structures of thousands of cells to hunt food or to survive when food is not available.

Myxococcus xanthus bacteria are predators that eat other microbes. When they organize into 3-D structures, they can be visible to the naked eye. In this complex form, they swarm toward their prey in a single mass of bacteria working together in “ripples.” You can see them on the left side of the picture.

To capture their food, the swarms of Myxococcus xanthus microbes secrete enzymes that kill and digest the prey and then take in their nutrients. These predator bacteria hunt together because individually they can’t produce enough of the antibiotics to kill the prey, but together they are deadly to other microbes.

When there is a food shortage, scientists still find these bacteria working together to survive. They form a structure called “fruiting bodies” as pictured on the right. In that form, they can survive for years if necessary. As single cells, they would not survive.

Studying how these microbes work can help scientists design new antibiotics or pest-resistant seeds for agriculture. Myxococcus xanthus rods are alive and can crawl, so their movement applies the laws of physics and the biological laws that govern living things. Studying these bacteria may help materials scientists gain new ideas for constructing liquid crystal display screens in electronic devices.

We learn much by looking at what is functional in the natural world. A wonder-working hand has moved before us and gives us tools for developing new materials to improve our lives. Also, bacteria working together can serve as a lesson to remind us that humans can accomplish more when we work together.

Planetary Atmospheric Pressure

The media often overlook how many things have to be “right” for life to exist on a planet. Planetary atmospheric pressure is one factor.

By “life,” we mean the standard textbook definition of organisms that can move, breathe, respond to outside stimuli, and reproduce. The problem is that many conditions make other terrestrial planets (planets with hard surfaces) unlikely to harbor life. Life is even less likely on Jovian planets that are primarily gaseous. You can postulate balloon-like living organisms in Jupiter or Saturn’s atmosphere, but radiation and electrical problems make that unlikely as well.

Planetary atmospheric pressure depends on the weight of the gases above a planet’s surface. The air pressure on Earth’s surface is 14.696 pounds per square inch a sea level. That pressure allows water to exist as a liquid, and it will enable various gases to dissolve in the water. We all know what happens when you shake a bottle of carbonated beverage and then quickly remove the cap. The sudden drop in pressure causes an explosion as the dissolved carbon dioxide escapes from the liquid. For organisms to absorb oxygen dissolved in water, which fish do, the atmospheric pressure must be high enough for the oxygen to dissolve. The atmospheric pressure on the surface of Mars is .01 of the pressure on Earth. That means water on Mars would contain no oxygen or dissolved gases.

There has been discussion about finding water on the Moon or Mercury, but those atmospheric pressures are considerably lower than those on Mars. That means water would not be in a liquid state. On the other end of the pressure spectrum is Venus, where atmospheric pressure 92 times greater than on Earth. At that pressure, toxic gases would be dissolved in any water that existed on the planet.

Planetary atmospheric pressure is just one more variable that must be carefully and precisely chosen when constructing an environment that will support and sustain life. The creation is far more complicated than most of us realize. As we learn more, we must stand in awe of the God who created our planet.

Outer Space Is Not Dark

Every time we get a better view of outer space, a new mystery steps forward. In 2015 a spacecraft called New Horizons went past Pluto and raced into outer space. The computers onboard the spacecraft were programmed to block out all light from known objects in the Milky Way galaxy. You would expect that if no light from stars or galaxies could get into the light measuring devices on New Horizons, it would measure only total and complete darkness. Instead, what New Horizons told us is that outer space is not dark but incredibly brilliant.

Outer space has an amount of light equivalent to the light from all the known galaxies in space! Tod Lauer, a spokesperson for the National Optical-Infrared Astronomy Research Laboratory in Tucson, says, “There’s something out there unknown.” The most likely scenario for this unexplained light is that there are still more galaxies and stars or clusters of stars beyond the reach of our telescopes, illuminating the distant clouds of matter.

Astronomers have said that the size of the cosmos is not only larger than we can describe with our known science and mathematics, but it is also larger than we can imagine. David wrote in Psalms 139:7-12, “Where can I go from your Spirit? Where can I flee from your presence? If I go up to the heavens, you are there. If I make my bed in the depths, you are there. … If I say ‘Surely the darkness will hide me, and the light become night around me,’ even the darkness will not be dark to you, the night will shine like the day, for darkness is as light to you…”

There is so much about outer space that we don’t know, like why outer space is not dark. But everything we discover points to the work of the Creator. It shows that He is a being outside of time and space who has created the cosmos with power and wisdom beyond our feeble ability to understand.

Ignore the Evidence or Accept the Evidence

One thing that impacts an apologetic program like ours is the attitude that evidence doesn’t count. We have seen that with COVID-19 during the past year. Some people are selective in whether they will accept the evidence or if they will ignore the evidence.

Nearly everybody in this country has, for many years, trusted the medical establishment. When we break a bone or have cancer, we go to a doctor or hospital. Most of us go to the medical establishment for problems such as arthritis, gastrointestinal issues, tetanus shots, and any number of pain issues. When the coronavirus pandemic began, many people chose to ignore the evidence presented by the medical establishment. As people started to die from the virus and hospitals were overrun, some people believed the whole pandemic was a hoax. Now that there are vaccines, people choose not to trust them.

This attitude of choosing to ignore the evidence if it inconveniences us has caused many people to reject God. I remember vividly when a young man came up to me after a lectureship at Purdue University. He said, “I can’t argue with anything you presented in your lecture, and I know the evidence for the existence of God is huge, but I’m not about to quit sleeping with my girlfriend.” That attitude has produced a society that promotes “survival of the fittest” and refuses to consider any possibility they should follow the Christian lifestyle.

The sad thing is the result of all this. I have friends who have lost a child, a parent, or a close friend and who stand there weeping as they say, “Why did this have to happen?” It didn’t have to happen!! How many of us are going to say as we stand in judgment before God and say, “Why do I have to spend eternity separated from God and everything good?” It doesn’t have to happen!! In Matthew 25:41-46, Jesus paints a picture of that very situation, and He simply reminds those who are lost that they refused to accept the evidence for God in the things they saw around them during their life.

Why Do We Need Mountains?

A skeptic recently complained that mountains are a mistake. “They block travel, cause avalanches, create deserts, and are just a general nuisance. If God were the creator, He wouldn’t have made these huge obstacles to human well-being.” In response to this skeptic, we consider, “Why do we need mountains?” For one thing, mountains are a very practical solution to one of humanity’s greatest needs–water.

In a basic geography or meteorology class, we learn about orographic uplift and rain shadows. As air comes across a flat area, it picks up moisture. But to make rain, there must be more than just water. Condensation requires a cool enough temperature and nuclei on which the water vapor can condense. Mountains provide both the cooler temperatures and the condensation nuclei.

As air pushes up the side of a mountain, it cools, and stirred-up dust provides condensation nuclei. For that reason, it is frequently very rainy on the windward side of the mountain. On the other side, the air is dry because all of the moisture has been removed.

Mountains can also capture and store water as ice and snow. Scientific American (January 2021) published an article with data on how many people get their water from the mountains. There are 78 regional mountain chains or “water towers” that deliver water to almost two billion people and surrounding ecosystems. Without mountains, the amount of land that would be hospitable to humans would be much more limited.

In addition to mountains capturing and storing water, they have also created underground aquifers. Glaciers generated in mountain areas have carved out huge valleys, depositing sand and gravel in permeable layers that allow massive amounts of water to seep into the ground. Here in southern Michigan, continental glaciers produced aquifers that supply us with water. In a large area of the Midwest United States, an underground aquifer called the Teays River has supplied adequate water for agriculture.

God has provided a massive and effective water system for nearly all continents, primarily because of mountains. Why do we need mountains? We need them for the water that allows irrigation as well as drinking and other uses. Mountains are beautiful, they provide recreational activities for humans, and they literally water the world for human survival.

Twin Study in Space

One of the most exciting experiments conducted on the Space Station has been the twin study in space. Mark and Scott Kelly are identical twins, and both are astronauts. Scott lived aboard the International Space Station for a year. Mark remained on Earth and lived his normal lifestyle. Both men took daily blood and urine samples so that scientists could evaluate any changes caused by living in space.

Life aboard the space station is very regimented and very different from Scott’s previous life on Earth. On the Space Station, fluids swelled around Scott’s upper body and head, his immune system worked overtime, and his metabolism was altered. Of greatest interest to scientists was that Scott’s genetic makeup – his DNA – had been damaged.

There are protective structures called “telomeres” at the ends of our chromosomes. These structures get shorter with age and put the person more at risk for age-related illnesses. In Scott’s case, the telomeres temporarily lengthened and then became shorter. This means that space flight could put the body at risk for age-related conditions such as heart disease and cancer.

In addition to the changes in the telomeres, there were other changes in Scott’s health. His eye shape changed, and his vision weakened. His cognitive speed also decreased. Scott’s risk of heart disease measurably increased.

What conclusion can we draw from the data of the twin study in space? First, the human body was designed for living on planet Earth. Even a small change in environmental characteristics can make genetic changes that can be detrimental to human health.

The experiment also shows useful facts about the human body. The effect of telomeres is interesting and may explain the changes in humans’ life expectancy in the past. The importance of taking care of the world in which we live is also apparent from this data. We can clearly see that God designed this planet for humans to live. We will have challenges if we start traveling great distances into space in the future.

The Message of the David and Goliath Story

Skeptics will go to almost any length to discredit the Bible. Science News (December 19,2020-January 2, 2021, page 14) published an article titled “Goliath Was Not So Giant After All.” The biblical record says that Goliath was six cubits and a span tall. The Science News article says four cubits and a span and then says, “…but don’t take that measurement literally.” The article misses the message of the David and Goliath story.

Fixed standards precisely define today’s measurement units. The ancient cubit was roughly defined as the distance from the tip of the middle finger to the elbow of an adult. Obviously, not all adults are the same size. So a cubit could vary between 17.5 inches and 21 inches (about 444 to 530 mm). The Science News article says that Goliath would have been 7 feet 10 inches tall. The New Bible Dictionary puts Goliath’s height at 10 feet six inches and says that archaeologists have found skeletons that tall in Goliath’s Philistine region of Gath. (We have not seen evidence for that.)

The Science News article bases their contention that Goliath was not a giant on the basis that Gath, the city from which Goliath came, had walls that were four cubits and a span wide. The author of the article is Jeffrey Chadwick of Brigham Young University, an archaeologist who has been involved in excavations around Gath. Chadwick says his discoveries show that the biblical descriptions of Goliath’s stature are metaphorical and not literal. According to him, 1 Samuel 17:4 is merely saying that Goliath “was as big and strong as his city’s walls.”

Lost in the debate about Goliath’s size is the fact that Goliath’s city of Gath was destroyed about 2850 years ago. That fits the time-frame of David’s defeat of Goliath and the conquest of his army. The bottom line is that the biblical record accurately describes what happened. It tells us that Goliath was a huge warrior and David was a small shepherd boy. The city walls’ size would have no more relevance than saying that the height of the doors of American buildings is the average height of NBA basketball players. We can’t know the exact size of Goliath, but that isn’t the message of the David and Goliath story. Despite the odds, David trusted God, and through him, God brought victory to His people.

Ant Armor for Leafcutter Ants

The study of insects continues to find design features that enable them to survive when it seems their enemies should wipe them out. The numerous ant species have a variety of defense mechanisms. Entomologists at the University of Wisconsin have discovered ant armor for leafcutter ants.

Leafcutter ants are small and must protect themselves from larger predatory ants. Researchers found that they have a tough coat of mineral armor. Entomologists studying Acromyrmex echinatior worker ants found that their exoskeleton has a thin white protective coating. After trying various methods to remove that mysterious layer, researchers discovered that it is calcite with high magnesium levels.

The thin protective layer, only 7% of the exoskeleton’s thickness, more than doubles the leafcutter ant’s hardness. When larger soldier ants of another species attacked, they were not able to kill the leaf cutterants.

Ant armor for leafcutter ants is similar to the mineral protection that crabs and other crustaceans have, but scientists had not discovered it in ants before. How did these ants get this protection? Researchers theorize that external microbes the ants carry are responsible. That means this is another example of symbiosis between species–another evidence of design. The scientist leading this study said that learning how this tough coating forms could help technicians develop protective coatings for various products.

It seems that God has given every species of life on this planet protection against their natural enemies. Not only must all lifeforms have a ready supply of food and adequate water, but they must have physical protection. Ant armor for leafcutter ants is only one example of God’s intricate design for life.
