The Death of the Dead Sea

One of the most interesting places on Earth is the Dead Sea. This body of water between Israel and Jordan is located 1400 feet below sea level at its surface. The lake is 978 feet deep and is fed by the Jordan River. The water is so salty that a person entering the lake floats so that most of their body is above the lake’s surface. The minerals that make the lake salty are essential and have been mined for centuries by simply evaporating the water. Health spas have sprung up around the lake, bringing in a busy tourist trade. However, we may be approaching the death of the Dead Sea.

The geology that has produced the lake is another interesting feature. The Jordan Rift Valley is a long depression between two geologic faults, known as a graben. Grabens are common on Earth, but this one is unusually deep.

One reason for the potential death of the Dead Sea is that in recent years it has been evaporating much more rapidly than ever before due to climate change. As a result, in some years, the lake’s surface has fallen four feet. As the lake level drops, numerous sinkholes have formed where the exposed ground that used to be at the bottom of the lake dries and collapses. As a result, an area that contained roads and beaches is now dotted with sinkholes making it too dangerous for travel.

However, the death of the Dead Sea has multiple causes. The Jordan River is essentially not flowing into the lake as people have diverted its water for drinking and irrigation. People also use evaporation ponds to recover minerals, accelerating the water loss. Between human over-use and climate change, the Dead Sea is rapidly becoming inhospitable to any human use or travel.

Concerned parties have proposed ways to stop water loss, but they require cooperation that is difficult to achieve. This is one more case where the human responsibility to care for what God has given us remains unmet. Trying to deny the problem exists is difficult when the evidence is overpowering. Human greed and exploitation, plus climate changes, may lead to the death of the Dead Sea.

How Fast Are You Moving?

If I asked, “How fast are you moving?” you might reply that you are sitting still. However, don’t forget that you are sitting on a planet that is spinning on its axis. A fixed observer in space would say that you are moving with the planet’s rotation at up to 1000 miles per hour if you are close to the equator. At the same time, Earth is revolving around the Sun at roughly 66,000 miles per hour. The Sun is one of 100 billion stars rotating around a black hole at the core of the Milky Way galaxy at approximately 400,000 miles per hour. Meanwhile, the galaxy is moving through space at around 2,200,000 miles per hour. So, how fast are you moving when viewed from a fixed point in space?

The amazing thing about the creation is that each of these numbers is critical for our survival. The spin of the Earth on its axis distributes heat in a way that we are not frozen or burned up. The revolution around the Sun keeps us from being drawn into the Sun or slung into outer space and frozen. The movement of the Sun around the galactic core prevents the black hole at the center of our galaxy from sucking in the entire solar system and destroying it. The galaxy’s movement through space prevents it from being absorbed by another galaxy. The speeds are critically fine-tuned because there is no tolerance for error.

As astronomers look at other solar systems and galaxies, they see the speeds that allow us to exist are not that common in space. The simple statement of Psalms 19 that “the heavens declare the glory of God, and the sky above shows His handiwork” reminds us that we are not the product of an accident. The more we learn about the cosmos, the more obvious it becomes that our existence is a product of intelligent design.

The psalmist also reminds us of the astonishing fact that the Creator cares about us. “When I consider your heavens, the work of your fingers, the moon and stars which you have ordained, what is man, that you are mindful of him …” (Psalms 8:3-4). So how fast are you moving right now? Fast enough to exist and to know that there is a reason for that existence. Read Job 1 and 2 and Ephesians 3:9-11 and 6:12 to learn more about that reason.

Alcohol Consumption During Pregnancy

The most destructive recreational drug on the planet is alcohol. The consequences of alcohol consumption are more than tragic accidents. New research on alcohol consumption during pregnancy indicates that the damage of alcohol is more pervasive than anyone believed ten years ago.

Researchers at the University of Vienna have revealed their fetal development studies showing that even one glass of wine a week by the mother can significantly reduce her baby’s brain development. The major damage was in the right superior temporal sulcus. That region of the brain involves social cognition and language development.

As the world moves toward acceptance of marijuana as a recreational drug, we can expect to see more problems with the development of children. As the adoptive parent of a child whose biological mother had not used good judgment during her pregnancy, I know the problems caused by alcohol consumption during pregnancy.

With careless environmental pollution and recreational drugs, having a healthy baby is more of a challenge than ever before. When our son was diagnosed with numerous congenital problems, some people told us it was God’s doing. We can’t expect God to constantly be undoing what we have done to ourselves, both individually and collectively.

UFO Sightings – Real or Bogus?

For over 50 years, we have reported explanations for bogus UFO claims. Unfortunately, when researchers have presented natural explanations for claimed UFO sightings, the media rarely reports them. Researchers have written books giving evidence to refute bogus claims of alien visitation to Earth, but they don’t get the attention of the sensational claims.

No thinking person would insist that planet Earth is the only place where life forms might exist. If God saw fit to create life elsewhere, it will be there. However, alien visitation to Earth is poorly supported by the evidence. The distance from Earth to where a life-bearing planet could exist is so great as to rule out any being traveling from another world. UFO advocates claim that aliens are so technologically advanced they can overcome the problem of traveling light-year distances. However, if they are that advanced, they could certainly prevent any detection by earthlings if they choose to do so.

The entertainment industry presents horror movies of aliens using earthlings for food or wars in space between competing alien societies. If you enjoy fantasy, these entertainment presentations may be worth your time. However, for serious students of science or the Bible, this is a useless diversion. We must not become worried or distracted by UFO sightings, thinking that extra-terrestrials are invading us.

Likewise, we need to solve our problems here on Earth and not expect some aliens to come in and do it for us. Besides, aliens could not improve on the message of Jesus Christ as revealed in the Bible. Human greed, selfishness, and exploitation of others will continue as long as humans entertain the notion that God does not exist and that survival of the fittest is our only choice.

Here are some books giving credible explanations of many so-called UFO sightings or Unidentified Aerial Phenomena (UAP).

Turtle Talk – in Slow Motion

Technology makes it possible to hear animal communication that has gone unnoticed before. We are finding that animals we thought were silent actually use sounds to communicate with one another. Researchers at the University of Zurich in Switzerland captured sounds from 50 species of turtles, and they varied widely, including grunts, chirps, snorts, and whistles. Male turtles use sounds to woo females and as warnings while fighting with other males. Turtle talk can easily go unnoticed because it is infrequent.

We often think of turtles as being slow. Apparently, that applies to their communication also. Timing is the key. The researchers report that some turtles make a sound every two days or so. That’s probably why it hasn’t been noticed by humans before.

The Creator’s design gives all forms of life a way to communicate with others of their species. That ability is essential for reproductive purposes and allows the full exploitation of food reserves and warnings about enemies. It is obvious that high forms of life, such as monkeys and apes, communicate with sounds, but as science learns more about animal communication, we find surprising things such as turtle talk. God has given all life forms the unique equipment they need to live in varied environments.

Archaeology Supports the Biblical Record

Skeptics maintain that biblical accounts of history are total fiction made up in recent times by promotors of the Judeo/Christian tradition. Recent research in the science of archaeology supports the biblical record regarding two of the examples some skeptics gave.

One is the Judges 4 account of judge Deborah and a Kenite woman who killed the Canaanite general Sisera by driving a tent peg through his head. Skeptics have claimed that no woman could have been a judge or a heroic avenger because of the lowly state of women at that time. Archeologists at the University of North Carolina at Chapel Hill excavating at Huqoq in northern Israel have uncovered ancient mosaics depicting Deborah and the Kenite woman, Jael, verifying the biblical account. The dating of the mosaics is late fourth or early fifth century A.D., so the claim that the account is modern cannot be true.

New studies of Mesha’s Stele have debunked skeptic claims that David is a fictitious character. The stele (an upright stone monument) was discovered in 1868 at a site east of the Dead Sea in modern Jordan. A research team from the West Semitic Research Project of the University of Southern California using a new research method called Reflective Transformation Imaging (RTI) has shown the reference in the Mesha Stele to the “House of David” is valid.

The science of archaeology supports the biblical record. We predict that as new tools become available, archaeologists will find more support for the credibility of the Bible.

Detailed discussions of these two new finds are reported in the Winter 2022 issue of Biblical Archaeology Review (Volume 48 #4).

Bird Brains and Efficient Neurons

In the 1950s, if you wanted to denigrate someone, you could call them a “bird brain” because people believed birds weren’t very smart. This assumption probably came from association with domesticated chickens. However, a 2016 study showed that bird brains are denser than those of many other animals. For example, a macaw has a 20-gram brain, and a squirrel monkey has a 30-gram brain, but they have the same number of neurons.

A new study of bird brains by researchers in Germany shows that bird neurons are more energy efficient than those of mammals. For example, pigeon neurons use three times less energy than mammal neurons. Birds are designed to do many things requiring brain power, including flying and singing complex vocalizations.

The lead researcher of this study suggests that the brains of birds are organized so that neurons can more easily exchange signals. Organization does not come out of random chance mutations. It requires an organizer. Watching birds around our feeders, we see them doing some incredible things. We know that they are guided by brains that have specific functions allowing them to find and use seeds and other food sources in the winter.

The brains of all animals are designed to allow them to live in a particular environment. What is unique about humans is that we can alter the environment rather than being altered by it. Also, our brains allow activities such as art, music, complex mathematics, worship, and the ability to be taught to think. Our spiritual nature sets us apart and allows our creative activity and our understanding that there is life beyond the grave.

Reading the Rocks in Wisconsin Dells

We have just enjoyed a return visit to the Wisconsin Dells. I say a “return visit” because, in the army, I was stationed at Camp McCoy near Sparta, Wisconsin. The closest place to go for an escape from military rigor was the Dells. Later, when I was in a National Science Foundation teacher training seminar, we spent a day at the Dells learning about the area’s geological history. I have been to the Dells nearly a dozen times and watched it change from a primitive camping area to a tourist water wonderland. As a geologist, I enjoy reading the rocks in Wisconsin Dells.

The Dells area is geologically interesting because the glaciers did something unusual there. For reasons still debated by geologists, glaciers that covered all of Wisconsin went around the Dells area. That left a very different geology compared to the rest of the state. Where we live in Michigan, glaciers dominated the whole state. Our house sits on a glacial moraine where glaciers dumped sand and gravel as they moved south.

In our gravel pits, we find rocks that came from hundreds of miles north of us. When I took my earth science students on field trips to area gravel pits, they found pieces of copper from the upper peninsula and Jasper conglomerate from southern Ontario. There is no exposed bedrock in southern Michigan, only sand, gravel, and clay left by the glaciers. Hundreds of pothole lakes and ponds cover the area, making it home to a variety of wildlife not abundant in Wisconsin. Farming in our area involves fruits and berries that are rare in Wisconsin.

Reading the rocks in Wisconsin Dells tells us a whole different story with exposed sedimentary bedrock and very little sand and gravel. The area’s rivers are very different, with large pillars and buttes that were spared by the glacial ice, and very few ponds. The whole ecological area of the Dells differs from the surrounding part of the state, and the varied ecology provides different natural resources. For example, the grasses that grow in a place like the Dells provide grains not as easily grown in glaciated areas.

Reading the rocks in Wisconsin Dells tells us that God has provided radically different ecological systems for our benefit. If all areas of the planet were the same, that would limit the available resources. The wisdom of having multiple agents to prepare different soils, different amounts of water, and different mixing of minerals reminds us of the message of Proverbs 8:22-31. That passage personifies Wisdom as being there when God created all these things. Learning to read Earth’s geological history shows us the methods God used to prepare this planet for human habitation. How blessed we are to travel and see places like Wisconsin Dells and learn of God’s wisdom, love, power, and patience in all He does.

Observing Fibonacci Day

Humans look for ways to celebrate certain days. We laugh at Groundhog Day and use Valentine’s Day for special human relationships. Some days have extensive significance, such as Thanksgiving, Christmas, or Veteran’s Day. We are now observing Fibonacci Day on November 23. Fibonacci Day is an unusual celebration of a remarkable mathematical sequence.

Fibonacci was an Italian mathematician who noticed in the year 1202 some interesting oddities about a particular sequence of numbers: 1,2,3,5,8,13,21,34,55, 89,144, 233. Notice that when you add any two sequential numbers, you get the next number. For example 5 + 8 = 13; 8 + 13 = 21; etc. If you divide two sequential numbers, you get .618034, which some mathematicians have called the “golden mean.”

Applying this Fibonacci sequence to architecture, you get a practical application. A rectangle using any two sequential numbers is aesthetically pleasing to human eyes. If you cut a square off any of these rectangles, you get another rectangle with the Fibonacci sequence. If you connect the corners of the squares in a series of Fibonacci rectangles, you get a spiral (see sketch).

An amazing thing about this is that there are an unlimited number of examples of Fibonacci spirals in the natural world. A small sampling includes:
*The spiral arms of galaxies curl in a Fibonacci spiral.
*The curl of a wave in the ocean fits the Fibonacci spiral.
*The snail shells curl in a Fibonacci curve.
*Elephant tusks curve in a Fibonacci spiral.
*The roots of human teeth curve in a Fibonacci spiral.
*Spider webs fit the Fibonacci spiral
*Keys on the piano are 5 black and 8 white, 13 in all, fitting the ratio.

*Musical chords producing pleasing sounds have the Fibonacci ratio.
*Bacteria growth curves fit the Fibonacci ratio.

There is no natural or evolutionary reason for the Fibonacci sequence. Notice it isn’t just in one discipline but in widely separated areas of study.

The Fibonacci Association publishes a magazine called the Fibonacci Quarterly, and people have written several books about the Fibonacci ratio. If you are observing Fibonacci Day, realize that this demonstrates God’s design in the creation. Chance does not produce a pattern across multiple disciplines like this.

A Mother Carries Her Child for Decades – Not Just Nine Months

We all know that a mother carries her unborn child for nine months until the baby is born. However, most people don’t realize that a mother carries her child for decades. That is true even of a woman who chooses to abort her child.

The term “chimera” (pronounced ky-mer-uh) refers to an animal made up of parts of different animals. It goes back to ancient mythology, which told of a creature made of parts from various animals, such as a goat, a lion, and a snake. The Bible even speaks about a vision of multiple animal combinations in the book of Revelation. However, in human mothers, scientists see microchimerism in which fetal cells and DNA are left behind in the mother’s body.

The unborn baby, commonly called a fetus, is not part of the mother’s body and has his or her own DNA. The baby is like a foreign object inside the mother. That’s the reason for “morning sickness,” as the mother’s immune system tries to reject it. The often repeated slogan “my body, my choice” does not consider that the baby is not part of the woman’s body and has no choice in the matter.

The placenta is the link between mother and baby. The unborn baby gets nourishment through the placenta as it connects to the mother’s arteries. However, the baby can also shed some cells and DNA, which enter the mother’s bloodstream as early as two weeks after conception. Those fetal cells can find a home in various organs of the mother, including her heart and brain. Since those cells are from a different person, the result is microchimerism. The woman has part of another person remaining inside of her body.

Scientists have found that a mother carries her child for decades as the baby’s cells remain in her. If she has more than one child, she can retain cells from each of them in her body. Just as science has found that stem cells can be helpful in medical treatments because of their ability to form into different kinds of cells, the potent cells from the baby can become pancreas, heart, liver, or brain cells in the mother. Or they can become skin cells. Scientists have found cells from the baby in the scar tissue after a caesarian birth, indicating that the baby’s cells are helping the mother to heal.

Not only do fetal cells continue in the mother after normal births, but also they are left behind when there is a miscarriage or medical abortion. Surprisingly, studies indicate that more cells are left in the mother after an induced abortion than in a natural miscarriage. Furthermore, this transfer of cells works both ways. To a lesser extent, cells from the mother can get into the unborn baby. Since cells from previous siblings are still in the mother, even those can be passed on to the fetus. In other words, a second or third child may have cells from his or her older siblings.

What does this mean? It tells us that a mother carries her child for decades. As mothers carry with them a part of their children, there is good reason for the bonding between mother and child. Even when a woman decides to end her baby’s life before birth, she still carries some of that child with her. Being a mother is a precious blessing, and abortion is not something to be taken lightly.
