Digital to Biological Converter

Digital to Biological Converter
The speed of scientific advancement in genetics and the use of computers in biochemistry is astounding. Scientists mapped the human genome in 2001. In May of 2018, Synthetic Genomics announced that they had created a working Digital to Biological Converter (DBC). The DBC turns digitized DNA code into synthetic biological material such as proteins. The process is called “Gibson Assembly” and can produce small pieces of DNA code called oligonucleotides and stitch the pieces together into DNA strands.

The exciting part of this new technology is that it could allow doctors to personalize medications to the individual needs of patients. Oncologists could create a medicine specifically targeted to the patient’s tumor. It has the potential to create vaccines to fight an epidemic quickly. The prototype machine is too large and too inefficient to be practical, but Synthetic Genomics hopes to have it available to medical researchers in three to five years.

Many of the health problems we have today whether genetic or otherwise have been caused by what we have done to ourselves and our environment with various chemicals and carcinogens. Some might say that we are “playing God” by creating synthetic genetic material. But if we have a way to correct the damage that our ancestors and we have done and relieve pain and suffering, we should certainly do it. The complexity of the Digital to Biological Converter and the material that it produces tells us more of God’s wisdom in the original construction of life.

Perseid Meteor Shower Peaks

Perseid Meteor Shower Peaks
In our post yesterday we mentioned that the Perseid meteor shower peaks tonight and tomorrow night August 11-12 and 12-13. Earth is making its annual journey through the trail of debris left by Comet Swift-Tuttle. When those pieces of rock, mostly ranging in size from a grain of sand to pea-sized, enter Earth’s atmosphere at supersonic speeds, they burn up from the heat of friction. We see the streaks as “shooting stars.”

Earth has been passing through the Swift-Tuttle debris since July 17 and will not be clear of it until August 24. So even though the Perseid meteor shower peaks this weekend, it is possible that you might see some of the meteors over the next few days. However, on these two nights, they should be visible at the rate of about one per minute. The best time to see them is after the Moon sets, and the best place is an area free of lights and with an open sky.

Every day anywhere from 100 tons to 1,000 tons of meteoritic material enters the Earth’s atmosphere. This material can come from comets or asteroids. The asteroid 3200 Phaethon produces the Geminid meteor shower in mid-December. There are other pieces of rock, dust, and debris in space that sometimes get trapped in the Earth’s gravitational field, and contribute to the hundreds of tons of material that reach Earth every day.

So what are the lessons we get from all of this? For one thing, Earth is not a static planet. It is gaining new mineral wealth every day. Our planet is vibrant and alive and has changed over the eons of its existence. The design of Earth’s defensive shield is incredible. With all of this material left over from the creation processes, it is critical that we have an atmosphere that is dense enough to burn up the space junk that comes toward us.

Every time scientists get a meteor sample we learn more about our neighbors in space. We knew a lot about the makeup of asteroids before science actually landed a spacecraft on one. Our knowledge of comets was advanced before we were able to leave Earth’s gravity and examine one up close. We continue to learn about the unique nature of the Earth, the Moon, the Sun, and the material that makes up our solar system.

While you are outside, take a look at Mars which is still closer and brighter than usual and visible until about 4 AM local time. Saturn will be visible until 2 AM. Venus will set about 9:30 PM and Jupiter at 11 PM. The planets travel near the ecliptic, the path of the Sun and Moon across the sky, so here’s your chance to enjoy them all. As the Perseid meteor shower peaks, it reminds us of the words of the psalmist: “The heavens declare the glory of God; the skies proclaim the work of his hands” (Psalms 19:1).

Perseid Meteor Shower

Perseid Meteor Shower
One of the most spectacular meteor showers of the year will reach its peak on the nights of August 11-12 and 12-13. This year’s Perseids will be exceptionally brilliant because the moon will be only a small crescent and will set early. You can best see the Perseid meteor shower after 12:00 AM local time.

The Perseids are interesting because they frequently feature a brilliant fireball which can actually cast a shadow or a bolide which is a meteor that explodes. The Perseid meteor shower gets its name from the fact that the meteors appear to come from the direction of the constellation Perseus which will be in the northeast for those of us looking up from the United States. However, you will see them streaking in any area of the sky.

The Perseid meteor shower is debris from the Comet Swift-Tuttle which was discovered in 1862 and returned most recently in November of 1992. These meteors are small particles usually no larger than a pea and as small as a grain of sand. They become visible at an altitude of 55 miles (88 k) where they enter the atmosphere with an average velocity of about 133,200 miles (214,365 km) per hour. Perseid meteors usually burn up by the time they reach an altitude of 50 miles (80 km) and never contact the surface of the earth. If they did, they would be called meteorites.

So, if you can, find a place away from city lights after midnight. Lean back in a lounge chair where you can see the expanse of the sky. The best viewing is with your unaided eyes. Binoculars or a telescope will not allow you to view the whole sky. Then just enjoy the beauty of God’s creation. We will have more on the Perseid meteor shower in our post tomorrow.

Why Such a Huge Universe?

Why Such a Huge Universe?
Here are some questions that are often asked by those who are skeptical of the existence of God: Why such a huge universe? How can we believe that a Creator cares about us when we are so insignificant in this vast cosmos? Those questions are worth considering.

There is no doubt that the cosmos is fantastically large. The Hubble Space Telescope aimed at a small area of sky no larger than one-tenth of the diameter of the Moon to take this Hubble eXtreme Deep Field photograph. The few bright spots with points of light radiating are stars. All the rest are galaxies—more than 10,000 of them in this picture! Some of them are as far away as 13 billion light-years, meaning that they were among the first galaxies formed.

If there are 10,000 plus galaxies in this tiny area of sky, that means there are 200 billion galaxies in the visible universe. Each of those galaxies contains an average of 200 billion stars. So why such a huge universe?

There were two critical factors at the beginning of cosmic existence—mass and expansion rate. If the total mass of protons and neutrons had been any less during the first moments of creation, hydrogen would not have fused into any elements heavier than helium. Then the nuclear furnaces of the stars could not have generated the elements carbon, nitrogen, oxygen, phosphorus, sodium, and potassium, which are essential for life. If the mass of protons and neutrons had been any greater at the cosmic creation, all of the original hydrogen would have fused into heavier elements like iron, and life would not have been possible.

The mass also affects the expansion rate. If the cosmic mass density had been less, the expansion rate would have been too fast to form stars like the Sun and planets like Earth. If the density had been greater, the expansion rate would have slower and all stars would have been much more massive than the Sun and would give off radiation too intense for any orbiting planets to sustain life.

In other words, the universe was fine-tuned from the moment it began! Why such a huge universe? Because it had to be. It has just the right mass and expansion rate for us to be here. We don’t think that was an accident. Through the study of astronomy and astrophysics, we can see HOW God created the universe we live in, and HOW He made it possible for us to live in it. The creation of the universe is not magic. It’s a feat of astounding engineering from the very moment of creation.

Special Star – Our Sun

Special Star – Our Sun
The Sun’s corona visible during the 2017 total eclipse.
Our Sun is a special star. In the past, scientists thought that it was just an average star. However, new studies in recent years have shown many ways that our Sun is unique.

A recent study by researchers at the Flatiron Institute Center for Computational Astrophysics under the leadership of astronomer Megan Bedell shows one more way that our star is unique. The study involved examining 79 “solar twins” of the Sun. These are other nearby stars that have nearly the same temperature and mass as the Sun. Using the HARPS telescope in Chile, they measured the spectra of each of the stars. A star’s spectrum of radiation indicates what elements the stars contain and the relative abundance of those elements.

The researchers measured the abundance of 30 different elements to a precision of two percent, which is higher than others had achieved. The ratios of elements such as carbon to oxygen and magnesium to silicon were nearly identical in the stars they studied, except for the ratios in our Sun. Our star has a lesser amount of metals and elements that make up rocks. Those elements are the ones which planets are made of, so we can probably assume that those elements were removed from the Sun to make Earth and the other rocky planets.

The stars which came closest to matching the Sun’s chemical composition were only a small portion of the total stars studied. They are also missing some of the materials that could build planets like Earth. However, in the search for exoplanets, astronomers so far have not found any planets orbiting those stars that are most similar to our Sun.

This study is fascinating, and there is much more to learn. We don’t know if science will ever find any potentially life-supporting solar systems and planets anywhere else. However, we do know that our Sun and this planet seem perfectly designed as a place for us to live and to study the vast universe. It is evident that we have a special planet orbiting a special star in a special place where we can observe and study God’s creation.

Biomass on Earth Measured

Biomass on Earth Mostly Plants
Biomass is the mass of living biological organisms. If you lumped all living things by category, what group of organisms do you think would have the greatest biomass on Earth? We aren’t talking about the number of individuals, but the mass of the different lifeforms.

The Proceedings of the National Academy of Sciences on May 21 published a study of the different areas of the world and what form of life dominates in those areas. (Click Here to read the full report.) Plants contribute the primary biomass in the terrestrial environment. Animals are primary in the marine environment. Bacteria and archaea (single-celled microorganisms) dominate the deep subsurface environment.

You may find the results surprising. The total biomass of Earth consists of 80% plants. Bacteria make up the second largest biomass at 15%. After that in descending order are fungi, archaea, protists (unicellular organisms that sometimes form colonies), animals (including humans), and viruses. Soil fungi, protists, soil archaea, arthropods, annelids, and livestock all exceed humans in their biomass. Only wild mammals, nematodes, and wild birds have smaller biomasses than humans. In the marine environment the biomass is much smaller than on land, and after animals, the greatest biomass is in protists, archaea, fungi, and finally bacteria. It is interesting that tiny Antarctic krill contribute about the same biomass as humans.

As you think about the biomass on Earth, it becomes evident that for human life to exist, we need a huge biomass of supporting life-forms. It becomes apparent that we must take care of all of the living things that support us. It is also obvious that before human life could exist on Earth enormous preparation was required.

We have to be reminded of the words of the psalmist in Psalms 8: “When I consider your heavens, the work of your fingers, the moon, the stars, which you have set in place, what is man that you are mindful of him, the son of man that you care for him… You have made him ruler over the works of your hands; you put everything under his feet: all flocks and herds, and the beast of the field, the birds of the air, and the fish of the sea, all that swim the paths of the sea.”

Why Gold Is So Precious

Why Gold Is So Precious
Have you ever wondered why gold is so precious? What is it about this metal that we can use it for so many things including the base of many national economic systems?

We think of gold as being rare, but it is quite abundant in the universe. Ten-billion tons of gold exist in Earth’s oceans. Scientists believe that near-Earth asteroid 433 Eros has more gold in it than has ever been mined on Earth. Gold is virtually indestructible. It is almost always recycled, and 85% of the gold ever found is still being used today.

The atomic structure of gold gives it an incredible range of applications. Because of its electron configuration, gold is not very active chemically. Gold is popular in jewelry not only because of its beauty but also because it is chemically inert and therefore does not tarnish. That same electron configuration makes it extremely malleable (able to be pounded into a sheet) and extremely ductile (able to be drawn out into a wire). A one-ounce piece of gold can be beaten into a sheet five-millionths of an inch thick or drawn out into a wire 50 miles long and 5 micrometers thick–one-tenth the diameter of a human hair. Gold wires are also very useful in electronics because gold is an excellent conductor of electricity. In computers and other electronics, gold plating of connectors gives low resistance electrical contacts that don’t corrode.

For 70 years the standard treatment for rheumatoid arthritis has been injections of a liquid suspension of gold salts which act as an anti-inflammatory, but scientists still don’t know why that works. A method of refining gold requires the use of highly poisonous cyanide. However, researchers have discovered microorganisms that eat trace amounts of gold and deposit them as larger nuggets. This can lead to gold processing that will be far less damaging to the environment than the old cyanide method.

As chemists look at the electron structure of gold, they see that it has been designed to do some amazing things. The design of the atom gives us some incredible materials that are of great value for many things. That is why gold is so precious. God has designed some amazing things for us, and gold is one that is high on the list.

American Marijuana Attitude

American Marijuana Attitude
A recent study showed that most Americans view marijuana favorably thinking that it has significant benefits and few risks. Science does not support the new American marijuana attitude.

The journal Annals of Internal Medicine published the new study on July 23. The researchers conducted an online survey of more than 9,000 people from all over the United States. They found that 81 percent of U.S. adults believe that marijuana has at least one benefit. The most common benefit mentioned was pain management. Other supposed benefits in people’s minds were the treatment of diseases and relief from anxiety, stress, and depression. At the same time, 91 percent of the respondents believe that marijuana has at least one risk. The most common risk mentioned was not medical problems, but legal. They also mentioned addiction and impaired memory. The bottom line is that the American public sees marijuana as having few health risks and significant health benefits.

The prevailing favorable American marijuana attitude is most likely due to the influence of the media. Some individuals and businesses stand to make a massive amount of money on marijuana, and governments see it as a source of tax revenue. In the meantime, the public is ignoring costs in healthcare, addiction treatment, traffic enforcement, and traffic deaths. In a previous post, we reported on a study of the effects of marijuana on the brain. The American Medical Association published information in the JAMA Internal Medicine on the increase in fatal car accidents in the United States on April 20 each year. That’s the cannabis celebration day on which thousands of marijuana enthusiasts light up at 4:20 PM in celebration of pot. The 4/20 celebration has grown as marijuana has become more widely available and legal. According to the JAMA Internal Medicine journal, there was a 12 percent increase in fatal crashes on April 20 and a 38 percent increase among drivers younger than 21.

Since Washington state legalized recreational marijuana in 2012, the percentage of drivers involved in fatal crashes who had traces of marijuana in their blood has doubled. One of the problems involves trying to set a legal limit for marijuana because its effect on the body is very different from alcohol. Blood alcohol level reliably predicts impairment. The level of THC (the chemical in pot) in the blood is not the critical factor until it enters the tissue of the brain where it has its effect. The THC blood level may be lower when the brain is most affected.

Getting high on marijuana makes changes in the human brain and smoking the weed has many of the same health dangers as smoking tobacco. It seems clear that the American marijuana attitude is changing, but it is also clear that we need to step back and think more clearly before our thinking becomes blurred by pot.

Science Shows Intelligent Design

Science Shows Intelligent Design
In attempting to discredit all evidence that God created the universe, many atheist periodicals try to paint all religious claims with the same brush. In truth, believers cover a wide range of viewpoints. There are those who reject science altogether, others who accept “theistic evolution,” and still others who see that science shows intelligent design in the universe and living things. It is not a question of intelligent design or science. Science shows intelligent design.

Some creationists vilify science and make God an illusionist who does magic tricks to produce what we see in the world around us. In their minds “God spoke it into existence” puts God in the role of not using natural processes. It also makes God deliberately deceptive. Both of those views conflict with the Bible. Genesis 2:8 says, “The Lord God planted a garden eastward in Eden.” Don’t you think that God used processes to plant the garden? He didn’t run a rototiller or spade up the ground, but he “planted” using a process. When Genesis 1:3 tells us “God said Let there be light, and there was light,” is the light coming from his voice as He speaks or did He use a process? In Proverbs 8, wisdom speaks calling us to have an understanding heart (verse 5) and saying that wisdom was with God in His creative processes (verses 22-30).

The Bible maintains that God in all of His creative activity did so with wisdom and purpose. Webster’s Dictionary defines science as “systematic knowledge.” Scientists seek to gain information about the world in which we live. This information is not just data, but it is also information about processes. None of this precludes God from “speaking it into existence.” We are simply learning how what God spoke became a reality. That is why we see passages like Psalms 19:1, “The heavens declare the glory of God; and the firmament shows his handiwork.” The creation process is an apologetic evidence for the existence of God as Romans 1:20 tells us, “For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made.”

Quantum mechanics is showing us a whole new concept of science. We now understand that the sub-microscopic world of atoms and electrons, quarks and mesons does not operate by the same rules as our world of planets and moons and animals. Quantum concepts such as simultaneity and duality tell us that the creation is more complex and amazing than we ever imagined. Concepts like string theory propose as many as eleven spacial dimensions involved in the production of the physical world. The definition of God requires an entity that is outside of space and time—in other words, in a dimension higher than our own. To believe that there is an intelligence involved in all of this is a faith issue, but believing that somehow it all happened by chance is also a faith issue.

Intelligent design does not negate science. Whenever we see evolutionary processes shaping and molding living things, it is evident that the design of plants and animals allows these changes to take place. Seeing intelligence in the design of the universe is not an attempt to discredit science. Science shows intelligent design. Faith in God allows us to recognize a personal cause for the creation around us as opposed to relegating the cause to mechanical accidents. Faith in God also gives us the ability to see a purpose for our own existence and the reason that there is something instead of nothing.

Should Christians Care About Global Warming?

Should Christians Care About Global Warming?
Global warming has been an issue from a scientific perspective for at least 60 years. I remember discussions about it in my college classes at Indiana University many decades ago. In the last decade it has become a political issue and in the last few years a religious issue. There is so much bad information in the media that it is no wonder many people are confused about what is true and what is not true. Should Christians care about global warming?

Let us first point out that global warming and local heat are two different things. The heat wave that you may have experienced in the summer of 2018 in the United States is NOT what global warming is about. It may be hot where you are and very cold somewhere else. Global warming is just that–global. Data shows that the average temperature of the entire planet is rising. This is not the first time it has happened. The history of the planet shows periods of global cold and global heat. The causes of these changes are many and complex. Earth is a large planet with multiple factors involved in how its climatic systems work. Variations in the sun, volcanic eruptions, asteroid and comet collisions, and human activity all can affect climate.

Does climate affect human life? Of course it does. It always has, and with our increased population the effect will be greater. Jesus told his disciples, “You will hear of wars and rumors of wars: see and do not be alarmed for all these things will come to pass but the end is still to come. For nation will rise against nation, and kingdom against kingdom and there shall be famines and earthquakes in different parts of the world” (Matthew 24:6-7).

Is human life affecting climate and should Christians care about global warming? Genesis 2:15 tells us that God put humans in the garden of Eden “to dress it and keep it.” God expects us to take care of what He created, and we have not done a good job of it. When we mismanage God’s gift to us, there are always consequences. Man-made synthetics cause a large percentage of cancer. We are in an opioid crisis because of materials we take into our bodies that affect us in a variety of ways. Those of us who live in industrialized areas have seen the ecological disasters caused by human greed and selfishness. Several years ago, the Cuyahoga River in Ohio actually caught on fire. I have seen areas like Ducktown, Tennessee, and Sudbury, Ontario, decimated by pollution. Fortunately, people worked to clean up those places. Right now we have a crisis in our oceans because of the foolish disposal of plastics.

The global warming issue involves many factors, and human actions are certainly some of them. To what extent humans are responsible can be debated, but the question of rising temperatures globally cannot be debated. Christians can lead the world in helping relieve the consequences of “famines and earthquakes in different parts of the world.” If your belief system is “survival of the fittest,” you will not get involved, but that is not the worldview of Christians.

Jesus said, “Then shall the King say … Come you blessed of my Father, inherit the kingdom prepared for you from the foundation of the world: For I was hungered and you gave me food to eat: I was thirsty and you gave me something to drink: I was a stranger and you took me in: naked and you clothed me: I was sick and you visited me…” (Matthew 25:34-38). Global warming may cause much suffering on our planet, whatever its cause. Should Christians care about global warming? Yes, and the followers of Jesus Christ will be there to relieve the pain.
