Pine Trees Stay Green in Winter

Pine Trees Stay Green in Winter
Have you ever wondered how pine trees stay green in winter? How can they keep their needles in the cold when leafy (deciduous) trees are barren? There is more than one reason for the winter beauty of the pines.

Water retention is one key to remaining green all year. The needles of pine trees have a waxy coating that acts as a water barrier. Their tubular shape also helps to reduce water loss, and a substance in the sap acts as antifreeze. The water that remains in the needles allows them to carry on photosynthesis, even in cold temperatures. The water and the antifreeze component are delicately balanced allowing pine trees to live in cold or hot climates.

But there is another trick pine trees use to stay green, and that is overlapping of the needles’ time on the tree. Different pine species have different time schedules. White pines (Pinus strobus) retain their needles for eighteen months. The needles of red pines (Pinus resinosa) and jack pines (Pinus banksiana) stay on duty for two-and-a-half years. Various pines are on different schedules. New needles come in the summer and needles that have finished their term of service drop off in the fall. We may not notice the transition unless we are watching closely because the pine trees stay green in winter.

Walk through a pine forest, and you will find the ground cushioned with a bed of old needles. Pine needles outlast their leafy counterparts, but like all living things they don’t live forever. We think the design of pine trees and their beauty in summer and winter is another demonstration of God’s wonderful creation.

Another Blood Moon

Another Blood Moon
This past Sunday night the Western Hemisphere experienced another blood moon. We often hear the phrase “blood moon” applied to total lunar eclipses. That’s because the Moon takes on an orange or red glow when the eclipse becomes total. It has nothing to do with blood and nothing to do with Bible prophecy. Lunar eclipses are natural phenomena which occur when the Sun, Moon, and Earth are in perfect alignment. Earth’s shadow falls across the Moon and gives it an eerie, orange glow.

I took this picture at about midnight local time when the temperature was hovering close to zero degrees Fahrenheit. Because of the cold, I didn’t get a good focus and didn’t stay outside very long. Numerous other people took better photos and posted them on the web. They all look similar since we were all seeing the same view. Our Moon always keeps the same face toward us. Some people refer to the back side of the Moon as “the dark side of the Moon.” However, there is no dark side. The Sun shines on the back side each time the monthly “new moon” occurs. The Moon is in tidal lock with Earth keeping the same side facing us year-round.

For those of us who live in North America, this will be the last total lunar eclipse for a while. We will not see another blood moon until May 16, 2022. (Asia, Australia, and the Pacific will see another blood moon on May 26, 2021.) Perhaps this will give us a little break from those who try to convince us that lunar eclipses are a prophetic sign. The only sign we see in total lunar eclipses is that the solar system God created is still working in the way He designed it to work. Days, months, seasons, and years (Genesis 1:14) continue as they will until God decides it is time to bring this present world to a close. And nobody knows when that will be.

Last July we posted an explanation of why the red color and what causes lunar eclipses. We encourage you to read that post by clicking HERE.

Gravity Force and Life

Gravity Force and Life
Four fundamental forces impact our lives: electromagnetic force, strong and weak nuclear forces, and gravity force. We couldn’t live without them. More than that, we couldn’t live without them being exactly what they are and carefully balanced against each other.

Gravity is the weakest by far. For example, the strong nuclear force is 10 to the 38th power stronger than gravity. That is one followed by 38 zeroes. That strong nuclear force holds the nucleus of atoms together, but it acts over very short distances within the atom. The gravity force acts on larger objects over much greater distances.

If gravity were as strong as any of the other three forces, it would crush you and everything else as well! Because gravity is relatively weak, you can stand and walk. But it’s strong enough that you can also jump without flying off into space. Gravity holds our planet together. It also holds Earth in orbit around the Sun at the right distance to allow life to exist. Gravity keeps our Moon in orbit around Earth, and the Moon’s gravity stabilizes Earth’s rotation and causes the tides which clean our ocean shores.

Gravity is also a major force in our weather, causing air masses to move as their density changes. A stronger force of gravity would create strong and destructive winds. Gravity even makes plants grow upward no matter which direction you place the seed in the ground.

As matter moves around in the cosmos, it’s attracted to other matter by gravity. Gravity formed the stars and planets. Planets are spherical because gravity force pulls them into that shape. It is also the gravity force that pulls hydrogen molecules together to form stars. When the hydrogen molecules reach enough mass, the gravity force squeezes them tightly enough to cause nuclear fusion. The fusion of hydrogen atoms turns them into the essential heavier elements that make up planets and our bodies.

The gravity force is just right to make the universe, stars, planets, and life possible. If it had been slightly more or less, none of these things would exist. We think the precision of the forces of nature is not an accident, but the design of a wise God.

Membrane Structure and Water – A Response

Membrane Structure and Water
In our January 10, 2019 post we discussed attempts to redefine life. Some scientists are doing that to justify the assumption that there are massive amounts of life in the cosmos. Is that true? We have pointed out that the Bible is silent on this subject. However, this question brings up some other issues about membrane structure and water. Dr. Phillip Eichman is a scientist with a Ph.D. in biology who has written many articles for our printed journal. He also wrote a book titled Understanding Evolution: A Christian Perspective. He made this observation of our previous post.

“I found your blog about the search for non-water-based life forms interesting. I took a course at IUPUI (Indiana University/Purdue University Indianapolis) called “Biological Membranes.” We spent a whole semester studying the structure and function of different types of biological membranes. It was one of the best courses that I have taken, and it really helped to pull a lot of things together.

“The professor had been a student or post-doc of Sidney Fox and was very critical of his proteinoid microsphere theory. He (my prof) believed that any life form must have a lipid membrane to survive.

“If you think about it, water is as essential to the formation of a membrane as are the phospholipids. It’s that hydrophobic/hydrophilic interaction that allows the membrane to form. Those compounds you mentioned are all aliphatic hydrocarbons and are nonpolar, so they won’t form any type of membrane like what we know about on Earth.

“When I was teaching even basic courses like Fundamentals of Biology, I spent a lot of time on the nature of the water molecule and also on membrane structure. Biology just doesn’t make sense without understanding those things.

“They may find something out there with a different type of membrane, but I will wait to see it myself. I used to tell my students that the membrane keeps the inside in and the outside out. Without that, a cell as we know it just won’t work.

“P.S. I wrote a short article on membrane structure 20+ years ago. It has been cited several times even though it was in an obscure journal. It is still accessible even though it is probably dated now. Here is the link: http://shipseducation.net/9-2/membrane.htm

James Watson’s Racial Remarks

James Watson's Racial Remarks
One of the most famous scientists in recent history is James Watson. Watson along with Francis Crick discovered the double-helix structure of DNA, and they received a Nobel Prize for their work. Even though he is 90 years old, Watson has been highly sought after as a speaker. James Watson’s racial remarks have changed things.

In early January of 2019, Watson was interviewed in a PBS documentary titled “American Masters: Decoding Genetics.” In that interview, he said that “genes are responsible for inferior intelligence among blacks.” There are so many problems with this claim that it is hard to know where to start. There are valuable lessons to be learned as well.

The claim that blacks have inferior intelligence is a very ignorant statement. I have a degree in psychometry which is the study of tests and how they are constructed and used. I.Q. tests are loaded with cultural bias, and there are many different types of I.Q. In my early days working under David Segal at Indiana University, I studied the Stanford-Benet I.Q. test and the Otis I.Q. test. As a personal demonstration of the problems with I.Q., my foster son Tim would consistently score 40-50 on the Stanford-Benet test, and yet he would score 90-100 on the Otis. The Otis was a test based on verbal skills. Because we read to Tim regularly during his childhood years, he had average verbal skills. The Stanford-Benet was not verbal but was based on reasoning. Tim was and is mentally challenged in those areas.

Many blacks do score lower on I.Q. tests that were written by upper-class whites in New England. On an I.Q. test written by a black author raised in a profoundly racist geographic area, blacks have better scores than whites. Unbiased testing does not support Watson’s assumption that blacks have inferior intelligence.

Another issue is that there are different kinds of intelligence. Koko, the gorilla trained by Penny Patterson, could use the sign language of the deaf. His I.Q. score was in the 90s, close to normal human values, on a test that measured literary capability. On a test that measured scientific reasoning, the scores were far lower. That test measured a different kind of intelligence.

Because of James Watson’s racial remarks, the laboratory he once led stripped him of honorary titles. The Cold Spring Harbor Laboratory immediately printed a statement saying Watson’s comments were “reprehensible and completely without a scientific basis and were a misuse of science to justify prejudice.”

The Bible describes humans as created in the image of God, and condemns all attempts to separate humans on any criteria. “There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female, for we are all one in Christ Jesus” (Galatians 3:28). Because a man is an expert in one field of study does not mean his opinions should be held superior to others. Watson is an expert on DNA. He is not an expert on racial origins or how our understanding of the function of DNA impacts areas as nebulous as intelligence. James Watson’s racial remarks make that clear.

Amoeba Can Solve TSP

Amoeba Can Solve TSP
A famous challenge in computer science is called “The Traveling Salesman Problem,” or TSP for sort. Scientists in Tokyo have found that a one-celled amoeba can solve TSP.

The problem goes like this:
Suppose you are a traveling salesperson going from city to city to sell your goods. You want to maximize your efficiency to make as much money in as little time as possible. You want to find the shortest path that will let you hit every city on your route one time and return you to the starting point.

There is no simple mathematical formula to find the best route. The only way to solve the problem is to calculate the length of each possible route and see which is the shortest. The problem gets exponentially harder as more cities are added to the route. With four cities there are only three different routes to consider, but with six cities there are 360 different routes. If you had ten cities or more, the number of routes could be in the millions. With an increase in the number of cities, the number of routes increases logarithmically.

The traveling salesman problem is one of a broad class of problems computer scientists call “NP-hard.” (NP stands for nondeterministic polynomial time. People involved in hacking encrypted systems and mining cryptocurrency are interested in this sort of problem.)

At Keio University in Tokyo, scientists have discovered that an amoeba can solve TSP, with the help of some human ingenuity. They used a single-cell slime mold amoeba known as Physarum polycephalum which moves toward food and away from light. The scientists built a chamber filled with channels and placed some food at the end of each channel. The channels represent a city on the salesman’s route. The amoeba would extend tendrils into the channels to get the food. As it reached the food, a light would go on in that channel so that the amoeba would not go back to the same “city.”

The advantage is that that the amoeba doesn’t have to calculate every individual path as most computer algorithms do. Instead, the amoeba just reacts passively to the conditions and figures out the best possible arrangement by itself. What this means is that for the amoeba, adding more cities (channels) only increases the time linearly rather than logarithmically.

The lead study author Masashi Aono said, “The mechanism by which the amoeba maintains the quality of the approximate solution, that is, the short route length, remains a mystery.” If researchers can figure out how the amoeba can solve TSP, it could speed up our ability to solve all kinds of challenging computational problems.

This design feature in one of God’s simplest creatures is another demonstration of how we can know there is a God through the things He has made” (Romans 1:19-23).

Alien Life Without Water

Is Alien Life Without Water Possible?
For all of my life, there have been articles, videos, and public presentations claiming that there must be life elsewhere in the universe. Now that we know there are thousands of planets in the creation, we see attempts to maintain that with so many planets there must be life somewhere. Scientists are even speculating alien life without water.

We need to remember that the Bible doesn’t say that this is the only planet where God created life, so this is not a biblical issue. The latest attempts to expand the window of what life is has rejuvenated the need to show the design built into the development of life. Life on Earth is based on carbon, hydrogen, oxygen, and nitrogen. The National Science Foundation has just funded a three-year program at Saint Louis University to explore what building blocks might be used to make a different kind of life. The chemicals they are considering are hexane, ethers, and chloroform. There is particular interest in whether these materials can form membranes that could be considered life.

The first problem is the definition of life. Life has traditionally been defined as “that which can move, breathe, respond to outside stimuli and reproduce.” An extraordinary chemistry is necessary to meet all of these criteria. Water is the basic substance of life on Earth. The water molecule is polar, meaning that one end of the molecule is negative and the other end is positive. Oxygen is the negative end. Oxygen’s bonding orbitals allow the attachment of two hydrogen atoms making that end positive. This polarity allows water to dissolve other molecules. Salt, for example, is made up of sodium which is positive and chlorine which is negative. When you put salt in water, the sodium is attracted to the oxygen end of the water molecule, and the chlorine is attracted to the hydrogen end of the molecule because unlike charges attract each other. This pulls the salt molecule apart and allows the salt to dissolve. Alien life without water seems impossible.

Hydrocarbons like methane have four hydrogen atoms attached to the carbon atom symmetrically. That makes the molecule non-polar and unable to dissolve salt. Numerous experiments are underway to circumvent this problem including the use of vinyl cyanide (also called acrylonitrile) which has been found in the atmosphere of Saturn’s moon Titan. Coming up with a formula for alien life without water will be difficult. How a substitute for oxidation would work has not even been publicized, so respiration would be an equally great challenge.

Chris Butch, a chemist of the Earth Life Institute, says “It’s like trying to build a car in your backyard out of lawnmower parts, versus having the Maserati factory build a supercar.” As science looks for something that can be called life elsewhere in the solar system, we should be impressed with the wisdom involved in the original building of life on planet Earth.

Critical Initial Mass Function of the Sun

Critical Initial Mass Function of the Sun
Yesterday we discussed the question of what real creation is about. Our point was that the study of real creation involves the study of how time, space, and matter/energy came into existence. Those sciences are in the embryonic stage, but they point to there being a purpose that involves wisdom and contributes to our understanding of the nature of God. One important finding of the study of creation is the critical initial mass function of the Sun.

As we study the Sun, we see that much is unique about our star. It is not just an average star of the billions formed from the “big bang” and classified in the Hertzsprung-Russell diagram. As we watch stars forming today and, as we look at the composition of the galaxy we live in, much stands out in our understanding of the Sun. Our mathematics indicate that there is what we call a critical initial mass function of the Sun, or IMF for short. IMF is the mass needed for star formation to take place. When stars begin to form from the material in the creation, they must have enough mass to allow gravity to fuse hydrogen into helium. If that mass isn’t there, what you have is a brown dwarf. If the mass is .08 of the solar mass, a red dwarf will form.

There are roughly 400 billion stars in the Milky Way, and 300 billion of them are red dwarfs – also called M dwarfs because of their spectral identification. There are roughly 15,000 places in our Milky Way galaxy where we see stars forming, so we can watch the way in which the IMF functions. When our Sun was formed, an IMF had to be carefully chosen so that it would produce a spectral G type star. Other star types such as O, B or F types would be too hot, too active and have too short of a lifespan. The most numerous stars in our galaxy – the red dwarfs mentioned earlier – have similar difficulties with their activity including stellar flares and coronal mass ejections. None of these types of stars can be seen as possible solar systems where life could exist.

The critical initial mass function of the Sun seems to be fine-tuned for life to exist. While we may have believed that by faith for many years, we now have scientific evidence to support that belief.

Real Creation and Science

Real Creation and the Big Bang
In virtually all areas of science, one thing is always true. That is when we answer one question, we find many others. No area demonstrates this better than the subject of real creation.

By real creation, we mean an understanding of how the cosmos came into being out of nothing. What we are not talking about is the processes of biological change which is known as evolution. Darwinian evolution is not an alternative to creation because it is an entirely different subject. Darwinian evolution studies changes in biological systems which have already been created. It has nothing to do with the processes involved in creating the physical universe including time, space, and matter/energy.

There is massive evidence that the cosmos began in a singularity–a point of incredible temperature and density. We call that the “big bang” understanding, but science has no idea what banged or who banged it. We can describe with mathematics what happened between 10^-35 and 10^-32 seconds after that event. But quantum mechanics agrees with the biblical account that it was not a physical process which can be explained by classical physics. We can use classical physics to describe what continued the formation of the cosmos as we see it today. However, that is still not real creation because it only deals with changes in what was already created.

Astronomy magazine published an excellent article by William Jones in their February 2019 issue, page 68. Dr. Jones, a professor at Princeton University, gave a summary of how cosmologists approach the question of real creation:

“The answer is the combination of a big extrapolation and even bigger assumption based on a solid hunch and the surety of our ignorance regarding what is really going on. The truth is, everything about the early universe is speculative, and that is precisely why we study it.”

Dr. Jones then goes on to explain what our current guesses are and what we base them on. For those of us with a scientific interest and background, this kind of study helps us comprehend the nature and power of God. We hope to learn more about the processes involved in preparing a place for us creatures created in God’s image to exist as we transition to the dimension where it all started.

In addition to helping us comprehend God’s nature, these studies help us see the wisdom of God and His planning. Proverbs 8:22-32 brings us to understand wisdom’s role in real creation. Tomorrow we will take a look at the intricacies of making a star and placing it so that life can exist.

Chocolate Flies at Work

Chocolate Flies at Work - Cacao Tree Flowers and Pod
Thank God for chocolate flies. No, we are not talking about chocolate-covered houseflies. That sounds repulsive to us too. We are talking about the tiny flies that are essential to the production of the chocolate we love.

Chocolate comes from the seeds of the cacao tree (Theobroma cacao) which is native to the rainforests of South America. When early tribes in the Amazon and Orinoco River area discovered uses for the cacao tree, they started what became a chocolate craze that is still going on today. From there, interest in the trees and the tasty substance they produce spread to more of northern South America, into Central America, and into Mexico. The Aztecs even used cacao beans as money.

However, growing the cacao beans is not easy. The tiny white flowers that produce the beans require a small insect pollinator. The flowers grow out of the trunk of the tree where pollination by a bird or mammal would not be practical. Even bees or butterflies are too large. That’s where the chocolate flies come in. The pollinators that can do the job are tiny flies, or midges, in the family Ceratopogonidae. They are small enough to get into the flowers, and they are on the right work schedule. The cacao flowers open just before dawn—a time when the midges are most active. It seems like a planned arrangement. They are not really chocolate flies, but they are essential helpers for chocolate farmers.

As farmers began to grow cacao on plantations, the pollination process was not working well. Human pollination of the flowers by hand is a difficult job and not as effective as the work of the little flies. The midges were not doing the job because they prefer the shade of the rainforest over the open spaces of cacao plantations. Coincidentally cacao trees grow well in shady areas.

Farmers found a solution by planting small areas of cacao in the ecosystem of rainforest areas. Of course, that limits the areas where it can be grown and thus the amount of chocolate produced. However, the people of the world will not give up their desire for chocolate, and a fly the size of a pin-head makes it possible. This is just one more example of the importance of rainforests and the excellent design God has given this amazing planet.
