Will Scientists Be Able to Clone Mammoths?

Mammoths are an extinct group of mammals whose fossils are found in Asia, Europe, and the Americas. As the drawing above shows, they probably looked a lot like elephants, but they had significantly more hair and long, curved tusks. Scientists have learned a lot about these animals, since they left behind plenty of well-preserved remains. Some have even been found frozen, with skin, internal organs, and even DNA preserved. Well, a find out of the New Siberian Islands might have just surpassed all other finds when it comes to preservation.

Russian scientist and head of Northeast Federal University Mammoth Museum, Semyon Grigoryev, led an expedition that was specifically looking for well-preserved mammoth remains that could possibly be used to bring mammoths back from extinction. Since parts of the permafrost in Siberia have been thawing in recent years, they believed that frozen mammoth remains might be in the process of being exposed for the first time. They thought that if they could find such remains, some of them might be well-preserved enough to contain the materials necessary for cloning, which might end up producing living mammoths!

Recent reports indicate that the team might have, indeed, made just such a find. According to news reports, the researchers found a mammoth whose lower body was encased in ice. Not frozen soil – actual ice. This resulted in remarkable preservation for that portion of the body. The team says that the muscles are pristine, and they have the red color you would expect from muscle tissue. Even more impressive, they say they have found what appears to be blood in the remains! The article linked above has a picture of tube that contains some of the liquid that the team thinks is mammoth blood. If the researchers can find living cells in the blood or any other part of the remains, they will be given to the Sooam Biotech Research Foundation for cloning in the hopes of producing live mammoths.

While this is all very exciting, I do have to add a few words of caution.

The Inquisition Strikes Very Close to Home

Dr. Eric Hedin is an Assistant Professor of Physics and Astronomy at Ball State University. He has 38 peer-reviewed publications to his credit in such diverse fields as integrated optics, electromagnetic theory, and nanoscience. He has also been put on notice by the Inquisition, because he is vehemently suspected of heresy. Why? He teaches a course called “The Boundaries of Science,” which seems to come from a (gasp!) Intelligent Design point of view.

There are actually two versions of the course: Astronomy 151 and Honors 296, the latter of which is one of three courses a student can use to fulfill his or her science requirement in the Ball State University honors college. The honors course description, which is similar to (but not the same as) that of the non-honors course, says:

In this course, we will examine the nature of the physical and the living world with the goal of increasing our appreciation of the scope, wonder, and complexity of physical reality. We will also investigate physical reality and the boundaries of science for any hidden wisdom within this reality which may illuminate the central questions of the purpose of our existence and the meaning of life.

That sounds like a very interesting course to me. In perusing the bibliography of the non-honors version of the course, I see that it includes intelligent design advocates, such as Dr. Michael Behe and Dr. William Dembski. However, it also includes opponents of intelligent design such as Dr. Charles Wynn and Dr. Hubert Yockey. In addition, there are theistic evolutionists such as Dr. Paul Davies and old-earth creationists such as Dr. Hugh Ross. There are several Christians on the list, including Dr. John Lennox, but there is also at least one atheist (Dr. Roger Penrose) and one person of the Jewish faith (Dr. Gerald Schroeder). There are also several whose religious persuasions don’t seem evident from their writings, such as Dr. Michael Seeds and Hans Christian Von Baeyer. Is it a balanced list? No. It is weighted towards Christianity and intelligent design. Nevertheless, most views that exist among scientists seem to be represented.

So what’s the problem? The Inquisition has decided that the course smells of heresy.

Blame ‘Climate Change’ Despite the Evidence

On May 20th, Oklahoma City and its suburbs were hit by a devastating tornado. According to the latest news reports, the mega-tornado killed at least 24 people, nine of them children. My prayers go out to those whose lives have been affected by this terrible tragedy. While the situation is clearly an emotional one, we can’t let our emotions get away with us when it comes to understanding the science behind this tragedy.

What do I mean by that? Well, consider what Senator Barbara Boxer said on the floor of the Senate regarding the tornado:

This is climate change. We were warned about extreme weather. Not just hot weather. But extreme weather. When I had my hearings, when I had the gavel years ago. It’s been a while. The scientists all agreed that what we’d start to see was extreme weather. And people looked at one another and said “what do you mean? It’s gonna get hot?” Yeah, it’s gonna get hot. But you’re also going to see snow in the summer in some places. You’re gonna have terrible storms. You’re going to have tornadoes and all the rest. We need to protect our people. That’s our number one obligation and we have to deal with this threat that is upon us and that is gonna get worse and worse though the years.

She then went on to talk about a bill she has sponsored. It would put a tax on carbon in hopes of moving people to alternative sources of energy so as to reduce the effects of “climate change.” While Senator Boxer’s words are an emotional call-to-arms, they fly in the face of the scientific evidence.

Scientific Fraud: A Surprising Study

Dr. Arturo Casadevall is the chair and professor of microbiology and immunology at Albert Einstein College of Medicine. He is also the editor-in-chief of mBio, an open-access, online scientific journal that is sponsored by the American Society for Microbiology. Because of this latter position, he is very concerned about fraud in the scientific community. As a result, he and his colleagues decided to perform a study that would aid in our understanding of what causes scientific papers to be retracted and what kinds of people are doing the retracting. The results were not encouraging.

First, he and his colleagues studied all the retracted articles indexed by PubMed as of May 3, 2012. In all, there were 2,047 retracted papers, and according to their results, most of them were retracted because of some form of “misconduct.” Furthermore, the most likely form of misconduct was either fraud or suspected fraud. They also noted the following:¹

…the incidence of retractions due to fraud is increasing, a trend that should be concerning to scientists and nonscientists alike.

So according to their analysis, fraud is the leading cause of scientific articles being retracted, and it is on the rise. As they note, this is a cause for great concern.

In order to understand more about the kinds of scientists who are committing fraud, the authors decided to do an extensive analysis of some individual cases. Specifically, they reviewed findings of misconduct that were published by the U.S. Office of Research Integrity. There were 228 individuals whose cases of misconduct had been filed, and nearly all of them (215 to be exact) were instances of fraud. When the authors of the study analyzed who was committing this fraud, they found some shocking results.

Exactly How “Green” are Wind Turbines?

Using the wind to produce energy is considered by many to be an environmental panacea. Consider the words of Greg Vitali, a member of the Pennsylvania House of Representatives:

Wind energy is better for the environment than coal, natural gas or nuclear energy. Wind turbines operate pollution free, do not add to climate change and use very little water.

At first glance, this sounds reasonable. After all, wind turbines don’t emit carbon dioxide, so they are not contributing to the horrible “global warming” that is supposed to happen this century. They also don’t seem to consume much. They just sit there, twirling in the breeze, making electricity for us to use. It’s not surprising, then, that wind power is the fastest-growing source of new electrical power in the U.S.

As the video above shows, however, wind turbines do have an environmental impact – they can kill flying animals. Of course, a video of one or two birds being knocked out of the air by a wind turbine is no cause for alarm. The real question is, “How often does this happen?” If a few hundred birds are killed each year by wind turbines, you can legitimately say that their impact on bird populations is relatively low. However, a recent study indicates that more than just a few hundred birds are being killed each year by the turbines that produce wind power.

Give Her What She Wants!

An old proverb says, “The way to a man’s heart is through his stomach.” Some birds, like Eurasian Jays (Garrulus glandarius), have their own take on that proverb. These birds are monogamous,¹ and they have an elaborate courtship ritual. Part of that ritual involves the male offering food to the female. For these birds, then, the way to the female’s heart is through her stomach. Obviously, the male wants to offer the female something appealing, but how does he know what she wants?

It has been generally assumed that the male simply offers the female food that he likes. After all, the ability to consider another individual’s feelings is rather advanced. There is some evidence that great apes are able to consider the feelings of human beings,² but in general, it has been thought that most animals don’t have the intellectual ability to realize that a different individual might have different feelings or preferences. A recent experiment involving Eurasian Jays indicates that might not be correct.

In the experiment, a male was separated from a female by a wire fence. The male could watch the female as she ate large meals of either moth larvae or mealworm larvae. The male was then given a single mealworm larva and a single moth larva. Consistently, the male would pick up the food that was not in the female’s meal and offer it to her through the wire fence. The researchers concluded that this was because the male realized the female would be tired of what she had eaten in her large meal, and therefore the other food would be more appealing to her. This, of course, would mean that the male realized the female might have a different preference than he did, and he took that into account when deciding what to offer her.³

Another Amazing Homeschool Graduate

I became interested in home education because while I was on the faculty at Ball State University, my best chemistry and physics students were homeschool graduates. The more I studied home education, the more clear it became to me that for most students, it produces a superior education. As a result, I started working with home educators, and eventually, I started writing curriculum for them. Over the years, I have been truly blessed to hear from homeschool graduates who have gone on to do great things in their chosen fields of study. For example, not all that long ago, I met up with Joshua Russell, an amazing homeschool graduate from Alaska. His performance in a summer college program was so impressive that he was awarded a full-ride scholarship to any school in the University of Alaska system!

Well, I recently heard from a justifiably proud parent regarding her homeschool graduate’s success. His name is Talal Younes, and the picture above shows him with one of his professors at William Carey University. The picture was taken at the Honors Day Convocation held by the university, and it shows him with the Senior Biology Award he received. This means that he was the outstanding senior biology student over the entire year. Of course, one award wasn’t enough for Talal, so he also received the Senior Chemistry Award at the same event!

As if that’s not enough, Talal’s mother was kind enough to share with me the title of his Senior Honors Thesis: “Proposal of a Novel Mechanism for Alpha-synuclein Induced Neurodegeneration in Parkinson’s Disease.” In order to receive graduation honors at William Carey University, a student must complete an honors thesis in his or her area of study. However, a student can’t just decide to do an honors thesis on his or her own. The student must be invited to do so by a faculty member who wishes to supervise the thesis. Thus, the very fact that Talal can do a Senior Honors Thesis tells you he was so impressive that a professor wanted to spend extra time and energy working with him!

Another Fossil Surprise

archie — This Archaeopteryx fossil, known as the "Thermopolis specimen," was analyzed chemically. The results were surprising to those who think it is millions of years old (click for credit)

Archaeopteryx is an extinct bird that we know only from the fossils it left behind. There are eleven discovered fossils in existence, and the one that is generally considered the most well-preserved is called the “Thermopolis specimen.” It was found somewhere in the Solnhofen region of Germany and was part of a private collection until it was acquired by the Wyoming Dinosaur Center in Thermopolis, Wyoming.¹ The Solnhofen Limestone formation, where it was probably preserved, is thought to be 150 million years old.² Because the specimen is so well-preserved, geochemist Roy Wogelius and his colleagues wanted to analyze the specimen chemically, to see if there were any chemical remnants of the actual bird still in the fossil.

How do you chemically analyze a fossil without destroying it? One way is to use the Stanford Synchrotron Radiation Lightsource (SSRL). This instrument produces high-intensity X-rays which are used to illuminate the material being studied. The elements in the material absorb these X-rays, becoming “excited” with the extra energy. In order to “de-excite,” they release that energy with X-rays of their own. The released X-rays are different for each element, so when you analyze the X-rays being emitted by the illuminated fossil, you can determine what elements exist in the fossil, along with their concentrations.

So Roy Wogelius and his colleagues teamed up with some physicists at Stanford University to analyze this incredibly well-preserved Archaeopteryx fossil. The results were surprising, at least to those who think the fossil is 150 million years old.

Are We Becoming Less Intelligent?

Somewhere around 200 BC, a man named Eratosthenes learned that at noon on the Summer Solstice in Syene, a man looking down a deep well would see no light in the well, because his shadow would block all the sunlight. He reasoned that this meant the sun was directly overhead in the city of Syene at that moment. Well, he lived in Alexandria, which was about 500 miles south of Syene. He measured the length of a pole’s shadow in Alexandria at noon on the Summer Solstice and from that determined the angle at which the sun shined on Alexandria when the sun was directly overhead in the city of Syene.

Why would Eratosthenes do this? Well, like all ancient natural philosophers (including the Christian ones who would come a few hundred years later), he understood that the earth is a sphere. If you are under the mistaken impression that most ancient people thought the earth was flat, you need to realize that this is a textbook myth that is repeated over and over again but is nevertheless quite false. Since he knew that the earth is a sphere, he used his measurement to reason that the distance between Syene and Alexandria is about one-fiftieth of the distance around that sphere. He then took the known distance between Syene and Alexandria and multiplied by 50 to get the total distance around the earth. The unit he used to measure distance (the stadium) had different definitions at the time, but assuming he used the one that was typically used for long journeys, his measurement was correct to within 2% of today’s accepted value.¹

Does that surprise you? It shouldn’t. In today’s culture, we think of ancient people as ignorant savages, but in fact, many of them were incredibly intelligent. According to at least one geneticist, they were probably more intelligent than we are! In a two-part series published in the journal Trends in Genetics, Dr. Gerald R. Crabtree states:²

I would wager that if an average citizen from Athens of 1000 BC were to appear suddenly among us, he or she would be among the brightest and most intellectually alive of our colleagues and companions, with a good memory, a broad range of ideas, and a clear-sighted view of important issues.

The 2013 Midwest Homeschool Convention (and abiotic oil)

I spent this past weekend speaking at the 2013 Midwest Homeschool Convention in Cincinnati, Ohio. The crowds were huge, and there was a lot of enthusiasm amongst both the attendees and the speakers. It seems to me that this convention was much like the conventions I remember from ten years ago: lots of enthusiastic homeschoolers listening and talking to lots of enthusiastic speakers about the joys, troubles, and triumphs of home education. It was wonderful.

I spoke a total of seven times on six different subjects. Two of my talks were given with Diana Waring, and I enjoyed them the most. She and I have different styles that seem to complement each other really well. As she puts it, I provide the “analytics,” and she provides the “warm fuzzies.” I am not sure that’s exactly right, but it’s probably close. We gave the same talks in Greenville, SC, and we will be doing them again in Springfield, Missouri and Kissimmee, Florida.

As is typically the case, the most interesting part of the conference for me was interacting with the attendees. I had a rather constant stream of parents and students coming to my booth to talk with me. Many of them asked questions, and I hope my answers provided some help. Others came by just to report on how they (or their children) were doing with my courses. I was really impressed to meet one young lady who had completed all of my textbooks! I have authored or co-authored eight texts, and most students get through five of them. Some complete six, and a very few manage to cover seven, but this young lady had gotten through all eight of them. As a result, she has already taken the equivalent of a year of university-level biology, a year of university-level chemistry, and a year of university-level physics. That’s pretty impressive!

I take questions from the audience in all of my talks, and at the end of one of my evolution-related talks, a man asked a question about abiotic oil. He had read a book by Dr. Thomas Gold entitled The Deep Hot Biosphere, which tries to make the case that both oil and coal are not fossil fuels. In other words, they are not produced by decaying dead things. Instead, they are produced by chemical processes in the earth and simply reworked by living organisms. I read that book many years ago, and while it is definitely worth reading (even today), I personally think that it really overstates the case.
