Colors of Fall and What they Mean

The beauty of autumn’s brilliant colors is an amazing testimony to the creative wisdom of God as well as an expression of His love of beauty. The colors of fall are caused by several pigments and the interaction of sunlight and sugar.

Most of us know that chlorophyll makes leaves green. When leaves receive reduced sunlight in the fall, they also have a reduced supply of nutrients and water, causing the chlorophyll to be removed. The chlorophyll masks two pigments that have different colors. Carotene is yellow, and several varieties of anthocyanins are red. Many leaves contain tannin, which is brown and is dominant in oak trees. Sunlight acting on trapped sugar also produces anthocyanins with various sparkling colors, which is why the color is so spectacular on a sunny autumn day in a maple forest.

As the days grow shorter, the reduced amount of sunlight causes a corky wall called the “abscission layer” to form between the twig and the leaf stalk. This wall will eventually break and cause the leaf to drop off in the breeze. The corky material seals off the vessels that supplied the leaf with nutrients and water and blocks any loss of sugars from the plant.

What is especially interesting is that the leaf colors are not all the same. Some vines produce spectacular colors. Poison ivy takes on a beautiful red due to a high concentration of anthocyanin. Aspen has a high concentration of carotene producing the vivid yellows which dominate the woods in the Rocky Mountains. In Michigan, we have maples, gum, aspen, and oak, giving us spectacular colors that vary from one location to another.

The colors of fall are a great testimony to the fact that God paid attention to aesthetics in the creation. If survival of the fittest were the only criteria for choosing the chemicals that allow plants to survive, it seems that there would be one best choice. Different chemicals provide a vivid, beautiful splash of color for humans to enjoy. Beauty is not part of the evolutionary model, but it speaks of God’s creativity, giving us a wonderful and beautiful world in which to live.

Recycling Enables the Natural Beauty

I have lived my entire life in the woodlands of North America. I love walking through the vast areas of pines, birches, maples, oaks, blueberries, ferns, mosses, aspens, and raspberries. To me, it is pure joy to sit in the woods or in a boat on a lake or river and listen to the sounds of nature. I especially enjoy the fall when the colors become vivid, and animal life is in a rush to prepare for winter. The falling of leaves to the ground, followed by frost and snow, adds its own magic to the joy of being in the woods. Recycling enables the natural beauty we enjoy.

What we are seldom aware of is the massive amounts of waste produced in the woods. We all know about leaves and probably have had some cruel words about them when they cover our lawns. The fact is that a constant rain of organic material falls to the floor of the woods. Limbs, bark, twigs, dead grass, moss, sawdust, animal excrement, and carcasses pile up year after year. Yet when you walk in the woods, the floor is made up of a thin, spongy layer of black soil. What happens to the massive amount of debris that falls to the forest floor every year?

The answer to this question is under-appreciated by most of us. Recycling enables the natural beauty of the woods. God has built into the forest an incredibly efficient recycling system. When something organic falls to the forest floor, it is swarmed on by bacteria, termites, ants, fungi, and worms, which form the basis of the food chain for higher forms of life. Nutrients in the woods seldom last longer than a few weeks at the most. Rain is moderate and percolates through these nutrients, rapidly helping them find their way back into the forest’s living tissues.

Those places where there are not dense forests have a completely different system of recycling. In the far north, where forests are not dominant, migrating salmon provide the ecological balance needed. In desert areas, the lack of ecological balance means that life for humans is difficult at best. Human survival depends on God’s recycling system. In some areas of the rich farmlands of America, we can measure the soil in feet. That allows us to grow our grain crops that sustain our existence, but those areas were built in an ancient forest.

God told us to take care of what He gave us. (See Genesis 2:15.) One part of caring for the Earth is to copy God’s recycling techniques. Recycling enables the natural beauty by replenishing the nutrients we take from the soil rather than polluting the air by burning them or polluting the ground by bagging in plastic and burying them.

Flash-Frozen Extinct Species

One of the weaknesses of evolution’s explanation of the origin of all living things is that it is built on an assumption called uniformitarianism. The idea is that “the present is the key to the past” meaning that no process operated in the past that is not going on today. If there have been global catastrophes wiping out most living creatures, then the theories of gradualism have a problem with explaining life’s origins. Flash-frozen extinct species indicate global catastrophes.

Many years ago, we reported on the 1979 find of an extinct steppe bison mummy near Fairbanks, Alaska. The perfectly preserved corpse had been frozen for thousands of years. The gold miner who discovered the mummy called it “Blue Babe” after the mythical Paul Bunyon’s ox. That was because exposure to air caused it to turn blue due to iron phosphate. Blue Babe (pictured) is now on display at the University of Alaska Museum of the North.

As the permafrost melts in Arctic areas, people are finding more frozen animals, including woolly mammoths and woolly rhinos. The latest one is a cave bear found on the Lyakhovsky Islands in Russia. Once again, the specimen is complete with all of the soft tissues intact.

These animals were preserved in a state we don’t see happening today. They seem to be flash-frozen, not just preserved by falling into a crevasse in a glacier. All of the animals found are extinct, but studies of their DNA and their preservation conditions are opening doors to the scientific research of the past.

As scientists find more flash-frozen extinct species, there will be revisions of theories about the history of life on Earth. One positive aspect of global warming is that it will expand our understanding of life in the past.

Radiation Levels on the Moon

God created planet Earth for us to live on, and He designed us with what we need to survive here. The more we learn about conditions elsewhere in the solar system, the more we see how unique Earth is. Recently we have seen research data concerning radiation levels on the Moon. Our studies reveal that astronauts on the Moon could get up to 1000 times more radiation than what we experience on Earth.

Dr. Kerry Lee at the Johnson Space Center in Houston has analyzed data from a Chinese-German team. The Germans used data retrieved by a Chinese lander named Chang’e 4. They compared it with data from a NASA orbiter that has been circling the Moon for over ten years. The two sets of data agree 100%. The primary risk factor for humans is cancer. The message is that if humans try to exist on the Moon, they will need thick-walled shelters for protection.

We take for granted the romantic idea that humans can wander around space, looking for new information about the stars and planets. In doing that, we fail to realize how carefully designed the Earth is to avoid the dangers of radiation in space. Astronauts in the International Space Station get three times less radiation than the radiation levels on the Moon.

Our upper atmosphere and magnetic field help to shield us from radiation. God carefully designed the Earth with features to protect us from radiation from the Sun and other stars. Proverbs 8:22-30 finds wisdom speaking about the creation. The more we look out into space, the more we see the necessity of wisdom in making a world where we can live safely.

Birds Can Predict Typhoons

A recent report says that birds can predict typhoons. The Yamashina Institute for Ornithology published the results in Marine Biology, showing evidence that black-naped terns can predict typhoons and use that information to facilitate their migration.

Researchers attached tracking devices to the terns and studied how their migration departure varied with the presence of these huge storms. The birds would delay their departure when a massive typhoon was about to cross their projected path. Jean-Baptiste Thiebot, the lead author of the study, said, “They seem to be able to predict it.”

This ability gives the terns several advantages. Avoiding extreme winds and rain is a good thing. Besides that, the storms churn up food to the ocean surface allowing the terns to stop periodically to eat on their journey. In 2017, when there were no typhoons in the study area, the birds delayed their trip much later and flew the journey without a stop.

Scientists are still studying how these birds can predict typhoons. Some research suggests that they are equipped with infrasonic detectors that pick up weather signals. Researchers are also looking at the tern’s ability to recognize changing clouds.

In any case, it seems the birds are designed with an ability to use weather to facilitate their migration. Robert Gill, a research wildlife biologist with the U.S. Geological Survey, says, “They are able to predict better than the best weather forecasters we have.”

Mighty Mouse Drug May Help Space Travel

One of the problems with space travel is that the human body was designed to live on Earth. When people are in weightlessness for an extended time, they lose muscle and bone mass. This loss can be as much as 20%. A possible solution might be called the “mighty mouse drug.”

Dr. Se-Jin Lee of the Jackson Laboratory at the University of Connecticut has published findings of a drug that blocks a pair of proteins that typically limit muscle mass. When scientists treated mice with this drug, they maintained their weight and muscle mass even when they were in the International Space Station for a month.

The application of this research can do more than provide a way for humans to survive a trip to Mars. It may also benefit people who are confined to a bed or a wheelchair.

This research reminds us that God designed our bodies to function in Earth’s gravity, just as He designed Earth to support life. Problems occur when we subject our physical bodies to forces they were not designed for. These problems require extreme solutions, and God has given us the ability to use science to find solutions such as the mighty mouse drug.

Antarctic Glaciers and Flooding

Two of the most massive Antarctic glaciers have broken loose from their land connections and are floating in the ocean. This is a concern because if both glaciers melt, there would be enough water to raise the world’s oceans by ten feet. It is not only another evidence of global warming but also a warning to the world that we must pay attention to the coming rise in sea level.

Understand that when ice is exposed to the air on land, it absorbs a minimum of heat, so melting on a landmass is very slow. In water, however, heat exchange is very rapid. We all know that hypothermia takes place when a human gets into icy water. The melting of ice is much faster once it is in water, and the Thwaites glacier, the larger of the two Antarctic glaciers involved, is one of the fastest-changing glaciers on Earth.

Job 38:22-23 refers to the “treasures of the snow” and says that this frozen water is “reserved against the time of trouble.” In Earth’s design, the snow and ice preserve water and provide a vital heat sink to the whole planet. We see evidence that the oceans have been much higher in Earth’s geological history than they are today. There have also been times when they were much lower. The polar ice caps have been the primary water storage areas. Glaciers are also part of the design of Earth to make it hospitable for Life.

If the sea level rises ten feet, imagine what would happen to the world’s major cities located on the edge of the oceans. Since the mass of these two glaciers is enormous, this is not an immediate threat. ( A recent NASA study says that at the present rate, the melting ice sheets would add 15 inches to the sea level by 2100.) But it is a potential catastrophe we can avoid if we recognize that the possible flooding is a consequence of human actions, not a vindictive act of God. We can avoid what has already begun to happen by taking care of the planet as God instructed us to do.

Look at the Evidence!!

If there is one phrase that needs to shout to everyone on the planet in 2020, it is “Look at the evidence!!” From the president of this country to the teenagers across this land, there has been a huge failure to look at the scientific evidence. Despite all the evidence for how the Covid-19 virus spreads, we still have young people who party without masks, even in a closed interior environment. In spite of the fires on the west coast, the significant increase in hurricanes in the Gulf of Mexico, the melting of the polar ice caps, and the rise in temperature of the oceans, we still have people denying climate change. Even within the Church, we have a disdain for scientific evidence.

Those who follow Jesus Christ should be the most likely to respond to evidence. Jesus appealed to people to look at the evidence. He told people to see for themselves that things are true. When Thomas was unable to believe that Jesus had risen from the dead, how did Jesus convince him? Did He engage Thomas in a philosophical/theological discussion about how the resurrection was logically reasonable? Did He demand that Thomas believe as a test of faith? Read John 20:27-29 and see what He did.

The fact is that the resurrection, all of Jesus’ appearances after the resurrection, and most of the miracles before He died were to provide evidence so that people could believe. Just like today, some people refused to look at the evidence. They suggested that the miracles were fake, but the kind of miracles Jesus performed could not be faked.

It wasn’t just the miracles that Jesus used to validate His existence as the Son of God. His teachings did that as well. The parables of Jesus were not unbelievable fantasy stories. They were practical, true-to-life, easy to understand evidences for the truths He was teaching. When Jesus talked about relying on God, did He use theological and philosophical models to convince His listeners? Read passages like Matthew 6:25-34. You will find Jesus talking about examples that everyone knew about–fowls of the air, changing one’s height, and the flowers of the field.

Using the things that God has created to teach and make doctrinal points is not denigrating God. Read Romans 1:19-32 and notice what Paul uses to convict the Romans of the destructive path they are following.

Today, we see vast numbers of people refusing to look at the evidence. We don’t need to engage them in philosophical discussions. We need to show them the evidence that God does exist, that He is the God of the Bible, and that Jesus is His Son.

Did Science Find Life on Venus?

The media loves to jump on any sensational scientific finding, even if their headlines totally misrepresent what science has discovered. We have seen several headlines suggesting that scientists have found life in the atmosphere of Venus. Did science find life on Venus?

The fact is that a Japanese robotic satellite that has been orbiting Venus since 2015 records data in the ultraviolet part of the spectrum. The satellite has detected spectra for the chemical phosphine (PH3). Phosphine is a flammable, toxic gas made of one phosphorous atom attached to three hydrogen atoms. It is difficult to make in a typical chemistry lab. Biologists know that there are microbes that can make phosphine. Finding the chemical in the upper clouds of Venus, where the temperatures are low enough for the gas to exist, raised some questions about whether microbes could have produced it.

It is possible that the phosphine could have been produced by conditions on Venus that are not available on Earth. Such conditions could be very low pressures, long term effects of ultraviolet light, and long periods of time. The environment of Venus is highly toxic, even to microbes, so microbe production is unlikely. Scientists have found many of the chemicals essential to life or possibly produced by living organisms on several moons in the solar system. The creation process produces chemicals that can be associated with life, including water. The environmental parameters of all of these places are so extreme that no astronomer expects to see an alien walking around.

The Bible doesn’t say that Earth is the only place where life exists, and it may be that God has created life elsewhere. As humans leave our planet searching for chemicals and materials to meet the 21st century’s needs, we may find a storehouse of essential materials, both metallic and biological. Did science find life on Venus? No. This newest media hype does not tell us anything we didn’t already know, but the discovery is interesting.

Our Atmospheric Shield

One of the fantastic and vital features of planet Earth is our atmospheric shield. We have often mentioned the NASA website Astronomy Picture of the Day (apod.nasa.gov). Every day NASA posts a different astronomy picture to show us something of the cosmos. This is an excellent service because most of us don’t have access to giant telescopes, and we can’t see light in wavelengths outside of the visible spectrum.

On September 12, 2020, NASA’s posting showed a time-lapse series of pictures taken by the New South Wales observatory in Australia. This observatory is located at 33 degrees south latitude in an area with minimal light pollution, so there is minimal obstruction of the night sky. The pictures were recorded on 372 nights and run like a movie. What you see are sporadic meteors, fireballs, meteor showers, and even a lightning sprite. The series shows over 1000 meteors.

Remember that this picture sequence shows a relatively small area of sky. This does remind us that there is a constant rain of dust, pieces of rock, and other debris coming down upon our planet. People working with communication satellites are well aware of this because of constant damage to the orbiting objects. For those of us on Earth’s surface, our atmospheric shield burns up most of the solid space material. We don’t have to worry about getting hit by space debris or getting sandpapered by the small dust particles coming from outer space. That is just the solid stuff. Our atmospheric shield also refracts away non-solid radiation such as x-rays and gamma rays.

Providing a place where life can exist is not as easy as some think. One of the reasons we are not finding life in outer space is that designing and implementing our atmospheric shield was vital for the existence of life, and doing that was not simple. It required intelligence and a carefully implemented design. The simple statement, “In the beginning, God created the heaven and the Earth” doesn’t tell us the incredible difficulty of doing that.
