Electroreceptors of Paddlefish

Electroreceptors of Paddlefish

The American paddlefish is an interesting but relatively unknown fish species. These fish have large paddle-shaped appendages on their foreheads, and they inhabit the murky waters of the Mississippi River and its tributaries. They can grow to six feet (183 cm) and weigh 150 pounds (68 kg). So what is the purpose of the paddle? The electroreceptors of paddlefish answer that question.

You might think that the paddle is a device to dislodge food from river bottoms. Some people called them “shovelnose fish,” assuming they used their paddles as a shovel. But paddlefish don’t dig for food, and lab experiments in 1993 showed the paddle’s real purpose.

Paddlefish are filter feeders that feed on tiny crustaceans and insect larvae that drift through the water as plankton. Many whale species are filter feeders that use comb-like baleen in their mouths to strain their food from the water. Paddlefish have comb-like rakers in their gills. They swim with their mouths open and filter their food from the water. But that doesn’t explain the paddle.

Paddlefish have poor eyesight and no sense of smell, so how do they know where to swim to find food? The paddle is covered with tens of thousands of electroreceptors that can sense extremely minute electric fields. Plankton emit signals that are similar to what doctors measure in electrocardiograms. Paddlefish use their electroreceptors to detect those signals and locate the plankton, even in murky waters.

The electroreceptors of paddlefish are similar to those of the platypus found in Australia. Many marine fish, including sharks, skates, rays, and some freshwater fish, can use weak electrical signals for feeding and communication. Those fish don’t need light or clear water to eat and maintain a balance in the environment. This ability is not something that evolved in the paddlefish because fossil evidence seems to indicate that they had electrosense ability very early in Earth’s history. We are amazed by God’s designs that we see in living things.

Women’s Emotional and Psychological Struggles Over Abortion

Women's Emotional and Psychological Struggles Over Abortion

One thing that gets lost in the abortion debate is women’s emotional and psychological struggles over abortion. Time magazine published a moving essay by atheist Stephanie Land, titled “My Lost Pregnancy Had a Name.”

Land writes about dealing with the burial of what she calls “a third miscarriage in six months.” It is a very personal and dramatic discussion of how an atheist deals with the mental gymnastics of ending a pregnancy, be it an abortion or a natural medical miscarriage.

Land said she believes in “the right to chose.” She had chosen to end a pregnancy before. This time the choice was made for her at five weeks, but she did not realize it until she had an ultrasound at eight weeks. She took two rounds of medication for her “body to finally let go of it” at 12 weeks. She says, “It was a blastocyst, not a baby named Ellis.”

For people on both sides of the abortion issue, there is a tendency to ignore the facts connected with ending a pregnancy. Attaching a scientific name to a conceived child, be it “embryo,” “zygote,” “fetus.” or “blastocyst” does not change the fact that it is an entity of its own. It is genetically set with human characteristics at conception, not at some later date. The mother’s body recognizes the conceived child is not a part of her body, resulting in morning sickness. Not ending a pregnancy has obvious lifetime implications, but ending one can also.

The point that shines out in Land’s essay is the continuing emotional struggle with choosing whether to end a pregnancy. All sides of this issue need to develop more empathy and understanding for women’s emotional and psychological struggles over abortion.

Women personally dealing with the issue are not helped by political battles, court decisions, or picketing. Land’s essay vividly shows the personal struggle, even for an atheist, and it is worth reading. If you don’t have access to the November 2-9, 2020, Time magazine issue, you can read the essay online HERE.

DNA Design and Science

DNA Design and Science

Most of us know that we have something called genes that determine our physical characteristics, which pass on to our children. Genes are pieces of a molecule called deoxyribonucleic acid (DNA). This molecule consists of two chains of alternating sugar and phosphate groups that coil around each other to form a double helix. These simple units line up in that double helix in a way that carries information much like the pages of a huge book. The DNA design carries much of the information that makes us who we are.

The complexity of the DNA molecule is astounding, and its size is even more so. If all the DNA molecules in your body were uncoiled and laid end-to-end, it would stretch from here to Pluto and back. Humans do not have the largest DNA molecules. A flowering plant native to Japan called Paris Japonica has a DNA molecule 50 times longer than human DNA. 

DNA was discovered in 1869 by Swiss Biochemist Friedrich Miescher, who called it nuclein. In the early 1940s, bacteriologist Oswald Avery discovered DNA’s connection to genetics. James Watson and Francis Crick discovered the double-helix structure of DNA design in 1953. 

Because the molecule is so large and complex, the opportunities to study it and make practical use of it are almost limitless. Scientists are using synthetic DNA to create vaccines. Some DNA vaccines have been successful in animals. At this time, some scientists around the world are working on COVID-19 vaccines using DNA.

Scientists are developing other uses for DNA coding. The Consortium for the Barcode of Life (CBOL) is working to establish barcodes to identify plant and animal species. The use of DNA has solved many criminal investigations. Modification of DNA has given us genetically modified foods.

There are two lessons we can learn from this. First, the complexity of DNA design boggles the mind. Suggesting that it is the product of random chance seems much less likely than the idea that an intelligence designed it. That leads us to the question of whether we are playing God in some DNA experiments. We have previously talked about genetically modified babies. The extreme complexity of DNA makes it much more likely for a human error, causing harm to others. Scientists working with DNA manipulation should be guided by reverence for the Creator and the life that He created.

Black Lives Matter in the Bible

Black Lives Matter in the Bible

Skeptics seem to use every crisis or injustice to make false claims about the Bible. In several recent references, skeptics have claimed that the Bible does not accept black people as human. That simply isn’t true. Black lives matter in the Bible.

The word “cush” means “black” in Hebrew, and we find it in numerous biblical passages. Most frequently, it refers to a geographical area in Africa. English Bibles often translate references to the land of Cush as Nubia or Ethiopia, and a person from there is called an Ethiopian.

Archeologists have found a wide variety of remains of the Cushite people because they were excellent soldiers and masters of horses and chariots. In 701 B.C., Tirhakah, king of Cush, defended Judah against the Syrian invasion of Sennacherib. His help and God’s hand saved Jerusalem at that time.

The denigration of black people is a modern, western activity. Ancient Greeks, Assyrians, and Egyptians did not show the racism of recent times. The Greek historian Herodotus wrote that Ethiopians were the “most handsome of all men.” In Song of Solomon, there is a love song between Solomon and a Shulammite girl in which she tells Solomon not to love her just because she is black.

The Bible and the history of Israel and Judaism do not show any denigration of those with dark skin. The book of Jeremiah credits Ebed-Melech the Cushite as a hero for saving Jeremiah’s life (Jeremiah 38:7-13).

When we turn to the New Testament, we find more evidence that black lives matter in the Bible. In Acts 8:26-39, we read of the Holy Spirit sending evangelist Philip to an Ethiopian who was in charge of the treasury of Candace, queen of the Ethiopians. He had come to Jerusalem to worship God and was reading the book of Isaiah as he traveled. Philip explained the gospel and baptized him.

Jesus made a point of dealing with the racial prejudice that existed at that time.
(See John 4.) Galatians 3:26-28 makes it clear that there were no racial, political, or gender boundaries in the early Christian churches–“There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus.”

Black lives matter in the Bible just as much as every other life because we are all created in God’s image.

Benefits of Thanksgiving

Benefits of Thanksgiving

In 1863, the Civil War was in progress when Abraham Lincoln made a Thanksgiving Day proclamation asking U. S. citizens to “set apart and observe the last Thursday of November next as a day of thanksgiving and praise.” Special days of thanksgiving had been observed in the colonies for centuries beginning with the pilgrim thanksgiving in Plymouth, Massachusetts, with the Wampanoag people in 1621. It wasn’t until 1941 that Congress finally designated the fourth Thursday in November as “Thanksgiving Day” thus creating a federal holiday. What are the benefits of thanksgiving, and I don’t mean just the holiday?

A person’s belief system affects how they observe and participate in the holiday. As America has become more prosperous and science and technology have made our lives more comfortable, we have bought into the idea that we are the sole controllers of what we have and what we will have in the future. “Survival of the fittest” has led to a mindset that we must be the fittest in every area of life. Some religions have adopted this mantra to justify the extermination of those who are not part of their faith. Genocide, abortion, euthanasia, racism, and abuse of all kinds are rooted in the mindset that “survival of the fittest” produces.

God has always encouraged His children to view thanksgiving as essential. In Leviticus 22:29, God told the Israelites to participate in a sacrifice of thanksgiving. Jesus Christ in Matthew 5-7. turned the notion of survival of the fittest upside down. He gave statement after statement about behaviors and beliefs that did not promote the survival of the individual but submission to and promotion of others. In Ephesians 5:4, Paul takes all of the loose talk, crudeness, and covetous behavior and says, “Instead let there be thanksgiving.”

So what are the benefits of thanksgiving? I don’t mean just the holiday but the daily and weekly way we think and act? Look at the living things all around and the stars and planets in the night sky. Look at family and friends. Look in the mirror and reflect on how blessed we are to be alive. A person who is not looking to how they can subdue someone else or get what someone else has is a person who is at peace. When Jesus calls us to live at peace with everyone, turn the other cheek, give to others, and show mercy and gratitude to others, He calls us to the real, meaningful things in life.

Nobody likes to be involved in stress, fighting, bickering, and war. As long as “survival of the fittest” is our key to living, those destructive drives will be a part of our makeup. They jeopardize our health, our relationships, and our joy at being alive.

A key to joyous living is one of the benefits of thanksgiving.
An attitude of gratitude should be a daily, hourly activity. Pause to give thanks every time you eat. Spend some time looking at your family and those around you. For the past four days, we have talked about faith in God as a foundation for our lives. With that faith, you can be thankful that God has made you a person who doesn’t have to live in fear of death and dying. Rejoice in the knowledge that this life is only a small snippet of our total existence.

Good Soils Are Vital for Survival

Good Soils Are Vital for Survival

Many years ago in Alaska, I had a discussion with a biologist who was studying the Alaskan soils. His study revolved around the fact that Alaska has very little soil and what it does have is developing. The lack of soil in Alaska has limited plant growth and made the ecology dependent on migrating salmon. Soils are complex mixtures of organic matter, minerals, water, air, and billions of organisms that form over hundreds of years. Good soils are vital for survival. President Franklin D. Roosevelt once said, “A nation that destroys its soils destroys itself.”

Research has shown that plants are designed to “call” for nutrients from the soil. A plant will release molecules called flavonoids, which cause bacteria in the soil to migrate into the plant and form nitrogen nodules on the roots. The nitrogen nodules generate food for the plant. If ample nitrogen is already available for the plant, it will not release the flavonoids.

This “hunger” by plants is vital to understand because many natural and human-caused processes can deplete the soil. Forest and brush fires, hurricanes, pollution, and climate change can deplete soils’ nitrogen content and kill plants. Studies of the giant sequoias in California have shown that the soil under them has twice as many bacteria as the soil under nearby sugar pines. We all know that bacteria influence human health, but bacteria also affect plant health and growth.

As our population increases and world climates change, it will become increasingly important to understand how soil allows us to feed our growing population. God’s design of the Earth includes providing the soils necessary to produce food. Good soils are vital for survival.

Glaciers and Treasures of the Snow

Glaciers and Treasures of the Snow
Glacier National Park

In Job 38:22, God refers to “the treasures of the snow” and “the treasures of ice.” In Job’s day, that may not have made a lot of sense. Even today, most people are not aware of the role glaciers play in our lives.

We are living in what scientists call an interglacial period when changes in Earth’s orbit have caused glaciers to melt. This interglacial period has been going on for some 12,000 years and is unrelated to any human-induced climate change. When scientists find evidence of forests, other life-forms, and human remains under the ocean’s surface, we can be sure that the sea level has been very different in the past.

Water molecules are designed in a way that allows glaciers to exist. A glacier is not a block of ice. When water is frozen and put under pressure, it behaves like a fluid. When I was teaching physics, we had a demonstration in which we froze a metal container of water and then used a piston to put it under pressure. The metal container had holes, and the ice would shoot out through the holes in a cylindrical form, just as any liquid or gas would do. Snow falls on the ground in a cold place and piles up, putting pressure on the snow on the bottom. The pressure changes the snow, and it begins to flow like toothpaste. Those gorgeous blue ice flows, the treasures of the snow, are glaciers.

So why is this a good thing for you and me? First, it locks up water, so it is available year-round. The amount of land area available to humans would drop radically if we lost all the glacial ice on the planet. As the ice melts, it does so gradually. Many areas of the world have water year-round only because slow-melting glaciers supply water in a controlled manner.

Many plants and animals depend on glaciers for their survival. Glacial algae get their water by producing dark pigments, which absorb enough sunlight to melt glacial ice. In that way, plants can grow in places like Greenland. The algae provide food for fish and other marine organisms in northern latitudes. Without the glaciers to supply drinking water for the bottom of the food chain, life couldn’t exist in northern marine environments.

Glaciers are also one of the strongest erosional agents in existence. Because of that, mountainous areas have u-shaped valleys with numerous cirque lakes and moraines. Glaciers have allowed a whole biosphere to exist in those mountainous areas. Human habitation in much of the Rocky Mountains is only possible because of the work of glaciers. Here in Michigan, we see and enjoy a continental glacial area where a vast ice sheet shaped the land and created thousands of lakes.

Job could not comprehend the full meaning of the words God spoke to him. Today, people who live where the glaciers have worked and are working can be thankful for God’s design of the “treasures of the snow.”

Human Expression in Music and Art

Human Expression in Music and Art

One evidence for the unique spiritual makeup in humans is our ability for creative expression in art and music. Attempts to claim elephant art, gorilla creativity, and chimp creative technique have not given convincing results. We believe that the presence of human expression in music and art, as well as worship, is because we are created in the image of God.

A recent study from the University of California seems to support this. The study involved 144 infants from age two months to 14 months. Researchers fitted babies with heart rate and skin monitors and observed them while they listened to a lullaby. It didn’t matter what language the lullaby was in; the babies responded similarly in all cases. Their heart rate slowed, their pupils became smaller, and their skin electrical activity declined. When the researchers played music that was not a lullaby, there was no response from the infants. Obviously, it was not just the sound that was involved, but the type of sound.

Years ago, there was an interesting story about a famous classical violinist who was playing a song that his wife did not recognize. She asked him what it was, and he couldn’t remember. Later his mother heard the discussion between the violinist and his wife and told them, “I know exactly what that song is. I was composing that song when I was pregnant with you, and I played it over and over as I wrote the song.”

Stories like this suggest that music is a designed part of the human spiritual makeup. It is not just brain activity but the soul that enjoys and creates music. Human expression in music and art touches our soul because we are created in the image of God.

Avoidable Pandemic of Hyperemesis

Avoidable “Pandemic” of Hyperemesis

It’s an avoidable “pandemic.” I put the word “pandemic” in quotes because using a drug is not a virus or bacteria. It is also not self-replicating and does not afflict innocent people. The pandemic we are talking about is cannabis hyperemesis syndrome.

As I write this article, eleven states have legalized the recreational use of marijuana, and 30 states have decriminalized it. One rarely publicized consequence of repeated marijuana use is recurring attacks of painful and protracted vomiting. It can continue until the esophagus rips, and the person bleeds to death. Since medical experts first identified this condition in 2004, the number of U. S. cases of hyperemesis has grown to over two million per year.

Your body stores cannabinoids in fat tissue, so weight loss, fasting, or alcohol consumption can trigger their release, resulting in hyperemesis. Colorado legalized the recreational use of marijuana in 2009. Since then, visits to emergency rooms for hyperemesis have doubled. The cannabis plant contains 100 different cannabinoids, but selective breeding has contributed to the hyperemesis surge. The THC content in marijuana tripled from 1995 to 2014, but the CBD content has been cut in half. CBD is supposed to decrease pain and anxiety.

Our society has turned away from God and the joy, fulfillment, love, and security He gives us. We will not find spiritual contentment in any chemical or alternative lifestyle. The acceptance of marijuana in our culture is one more tool of Satan to bring pain and destruction. As Christians, we must oppose it and this avoidable pandemic.

Does It Matter What People Believe?

Does It Matter What People Believe about Coronavirus?

For some of us, the tragedy of COVID-19 has really hit home. As I write this, my son is in the local hospital, fighting what may be a losing battle with the disease. As we have struggled to get Tim the help he needs, we have run into people who deny there is a pandemic. Many Americans believe that scams, lies, and conspiracies are behind claims that we are in a pandemic. Does it matter what people believe?

The University of Pennsylvania Annenberg Public Policy Center published the results of studies of what Americans believe about the pandemic in the journal Social Science and Medicine. According to their research, over 17% of all Americans believe that the pharmaceutical industry created the virus to boost drug and vaccine sales. Also, 24% believe that the government exaggerated the virus’s danger to damage Donald Trump politically.

There is no evidence to support those beliefs, and those of us who have family members dying from the virus certainly don’t endorse those claims. The Bible describes what happens when people change “the truth of God into a lie, and worship and serve the creature rather than the Creator.” The result is a culture in which people “do not retain God in their knowledge.” Instead, they are filled with “all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity, whisperers, backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents, without understanding, covenant breakers, …” (Romans 1:24-32)

Does it matter what people believe? Read those verses and then read the newspaper or watch the evening news. As faith in God and belief in the Bible have decreased, the use of lying and deceit has grown. We live in a society where lies and deception are a way of life. This ministry exists to change that by convincing people there is a God and that the Bible is a reliable guide to how we should live. Does it matter what people believe? Yes, it does matter.
