About a year ago I discussed a study that indicated a college education makes a person more likely to retain his or her faith. Recently, a new study on essentially the same topic was published in the same academic journal. It looked at data in a different (and very interesting) way, but its conclusions generally support those of the previous study.

The author, Dr. Philip Schwadel, used a well-known data set called the General Social Survey (GSS) for the years 1973 to 2010. He then looked at the years in which the respondents were born. He found that he had plenty of data for people born after 1900 and before 1980, so he focused on them. This gave him 38,251 people to analyze, which is an excellent sample size. In the GSS, the people are asked what their religious preference is: Protestant, Catholic, Jewish, some other religion, or no religion. They are also asked about their education and what kinds of degrees they have. Dr. Schwadel wanted to determine whether or not a college degree had any effect on a person answering “no religion.”

He found that people who were born from 1900 to 1964 were more likely to say they had no religion if they had a college degree. However, the amount by which they were more likely to say that dropped fairly steadily from 1915-1964. For those born in 1965, a college degree had no effect on whether or not they answered “no religion.” After 1965, having a college degree made a person less likely to indicate they had no religion. As the author says:1

Results from hierarchical age-period-cohort models using more than three and a half decades of repeated cross-sectional survey data demonstrate that the strong, positive effect of college education on reporting no religious affiliation declines precipitously across birth cohorts. Specifically, a bachelor’s degree has no effect on non-affiliation by the 1965–69 cohort, and a negative effect for the 1970s cohorts.

If we dig a bit deeper into the study, however, we find something even more interesting.

Confirmation of a Creationist Prediction Becomes Even More Stunning

Nature is filled with amazing designs, which leads me to the conclusion that it is the product of a Magnificent Designer. Of course, many scientists disagree with that conclusion, and some of them try to argue against it by pointing out examples of what they think are bad designs in nature. One of the oft-cited examples is the retina of the human eye. As Dr. Michael Shermer puts it:1

The anatomy of the human eye shows that it is anything but “intelligently designed.” It is built upside down and backwards, with photons of light having to travel through the cornea, lens, aqueous fluid, blood vessels, ganglion cells, amacrine cells, horizontal cells, and biploar cells, before reaching the light-sensitive rods and cones that will transform the signal into neural impulses.

To understand what he is saying, look at the illustration above. When light hits the surface of the eye’s retina, it has to travel through layers of cells that essentially connect the retina to the rest of the nervous system. Only then can it reach the light-sensitive cells, called rods and cones, and be converted into a signal that can be sent to the brain. This, of course, seems backwards to most evolutionists. According to them, if the retina were designed intelligently, the rods and cones would be at the retinal surface so they are the first thing the light hits. That way, the connecting neurons could be placed behind the rods and cones so they don’t interfere with the light in any way.

Like most arguments inspired by evolution, the more we learned about the human retina, the less reasonable this argument became. Back in 2007, a study published in the Proceedings of the National Academy of Sciences of the USA showed that light doesn’t have to travel through the connecting neurons to reach the rods and cones. Instead, as shown in the illustration above (which appeared on the cover of the journal), there are special cells, called Müller cells, that collect the light and guide it to the rods and cones.2

Three years later (in 2010), an analysis published in Physical Review Letters concluded:3

The retina is revealed as an optimal structure designed for improving the sharpness of images.

The authors of the analysis showed that the position of the rods and cones in the retina combined with the way the Müller cells guide the light to them make them much less sensitive to light that is scattered within the eye itself. This, in essence, reduces the “noise” that the rods and cones would get from errant photons, making the overall image sharper and clearer.

I blogged about this previously, pointing out that it is precisely what creationists predicted and quite opposite what evolutionists maintained. I am bringing it up now because further research has confirmed the creationist prediction in an even more stunning way!

Road Salt Changes Butterflies, Perhaps for the Better

Living in Indiana, I see snow plows spreading salt on the roads every winter. I don’t think much about them, because I have seen them all my life. However, I ran across an interesting study that indicates the salt they spread actually affects some of the insects that live near the road. Sodium chloride (the main ingredient in road salt) is such a ubiquitous chemical in nature that I never thought about how road salt might affect the flora and fauna that live near the side of the road, but the study indicates that for butterflies, the effect is significant.

The authors studied flora near the side of salted roads and found that the amount of sodium in the plants can be as much as 30 times what exists in the same plants that live more than 100 meters from the side of the road. That’s not very surprising, since most roads get salted quite a bit, especially during winters with lots of snow and ice. The surprising aspect of the study is the profound effect these elevated salt concentrations had on monarch butterflies that eat roadside milkweed while they are caterpillars.

The authors found that compared to monarch butterflies that ate milkweed plants in prairies far from the road, the male monarchs that ate salted roadside milkweed had much stronger flying muscles. The females were different, however. They had larger eyes than their prairie-raised counterparts.1 To confirm that it was really the salt having this effect and not some other chemical that might be found near the roadside, the authors reared cabbage white butterflies in the lab. They saw exactly the same effect – the males that ate a high-salt diet had stronger flying muscles, while the females had larger eyes.

Anyone who has been reading this blog for a while knows that I am fascinated with mutualism – the phenomenon whereby organisms of different species live together in a mutually-beneficial way (see here, here, here, here, and here, for example). I think it is probably a glimpse of what nature was like before the Fall. Based on what I see in mutualism, I think that lots of species were designed to cooperate with one another, and many of the pathological relationships we see today are corrupted versions of previously-beneficial ones.

Evolutionists have a different view, of course. The generally-accepted view is that mutualism starts out with one species trying to exploit another species. Here, for example, is how the text Symbiosis: An Introduction to Biological Associations, Second Edition puts it:1

Indeed, it is difficult to conceive of two organisms starting out in a mutualistic association. Most mutualistic symbioses probably began as parasitic ones, with one organism attempting to exploit another one.

To be fair, the authors of this text do allow for another option. There are some relationships between organisms that seem neither harmful nor beneficial. Barnacles that live on whales, for example, seem to neither harm nor help the whales in most cases. These kinds of relationships are called commensal, and the authors allow for mutualism to start out as a commensal relationship and then evolve into a mutualistic one.

The key, however, is the first sentence in the quote. They say it is difficult to conceive of two organisms starting out in a mutualistic relationship. Why? Because evolutionists cannot allow for a grand design in nature. They can’t look at the relationships in an ecosystem and see how they fit together in an overall plan. Instead, they have to imagine some scenario in which relationships are cobbled together by selfish organisms that are only concerned with their own survival. If organisms live in a mutually-beneficial relationship today, it is only because they evolved together (in a process called coevolution) from a negative relationship or at least a relationship that didn’t begin as a mutually-beneficial one.

A new study indicates that at least in some cases, this evolutionary-inspired idea is wrong.

Geneticists’ Bias Causes a Big Mistake

Posted by jlwile on July 31, 2014

This is one way to visualize a coding section of RNA.  It has a start codon that tells the cell to start making a protein, followed by a recipe for that protein.  Then there is a stop codon, to tell the cell that it is done making the protein.

This is one way to visualize a coding section of RNA. It has a start codon that tells the cell to start making a protein, followed by a recipe for that protein. Then there is a stop codon, to tell the cell that it is done making the protein.

You’ve heard it many times before. The vast majority of DNA is junk. Of course, the ENCODE project showed how wrong that notion is. Now that we know the vast majority of DNA is functional, you might wonder how in the world the idea of “junk DNA” became so popular among scientists. I suspect there are many reasons, but some recent research has revealed one of them – a bias regarding what it means for DNA to be functional. The research was done on molecules called long non-coding RNAs, which are commonly referred to as lncRNAs.

What are lncRNAs? Well, let’s start with what RNA is. The genes that your body uses are in your DNA, most of which is found in the control center of the cell, called the nucleus. In order for your cells to use those genes, they must be copied by another molecule. This process is called transcription, and the molecule that performs transcription is RNA. Once it has transcribed the gene, RNA leaves the nucleus, at which point it is often referred to as messenger RNA (mRNA), because it is sending a message to the cell.

What’s the message? It is a recipe for building a protein. That recipe is put together in informational units called codons, and it goes to a ribosome, which is a protein-making factory in the cell. The ribosome reads the codons, translating them one-by-one into a protein. Not surprisingly, this process is called translation. How does the ribosome know when to start building the protein? There is a start codon that tells it to start. How does it know when to stop building the protein? There is a stop codon that tells it to stop. As a result, you can think of messenger RNA in terms of the illustration above – it contains a start codon, a recipe for a protein (the blue bar in the illustration), and a stop codon.

So how does this relate to lncRNAs? Well, messenger RNA is referred to as “coding RNA,” because it codes for the production of proteins. LncRNAs are called “non-coding RNAs,” because it was thought that they do not code for proteins. Now there are lots of RNAs that are thought to be non-coding, but lncRNAs are relatively long. That’s how they get their name. Well, it turns out for at least some lncRNAs, every part of their name (except RNA) is wrong.

An Update on Mark Armitage and the Inquisition

This is Mark Armitage giving a talk at a meeting of the Creation Science Fellowship. (click for source)

Last year, I discussed how Mark Armitage fell victim to the evolutionary Inquisiton. In July of last year, he published a paper in the peer-reviewed journal Acta Histochemica. In that paper, he reported finding soft tissue in a Triceratops fossil that is supposedly 65 million years old. Remarkably, the soft tissue was composed of tiny, fragile cellular structures which showed no evidence of being mineralized. In addition, there was no doubt that this tissue came from the Triceratops, as it has exactly the microscopic structure one would expect for bone tissue.

That was too much for the High Priests of Science. The Inquisition struck, and Armitage was fired from his position at California State University. Armitage himself commented on the post, indicating he was convinced that his firing was directly related to the paper and he would sue the university.

Today, I ran across an announcement from The Pacific Justice Institute indicating that he has filed the lawsuit. The announcement includes something Armitage mentioned in his comment – that a university official proclaimed:

We are not going to tolerate your religion in this department!

A staff attorney for the Pacific Justice Institute is quoted as saying:

It has become apparent that ‘diversity’ and ‘intellectual curiosity,’ so often touted as hallmarks of a university education, do not apply to those with a religious point of view.

That isn’t news to me. It isn’t news to a lot of other Christians who happen to be scientists, either. It will be interesting to see how this lawsuit progresses.

A Great Story I Heard During a Radio Interview

I just finished an interview with Vivienne McNeny, host of an internet radio show called The Sociable Homeschooler. It was a delightful interview for many reasons, not the least of which is that Mrs. McNeny has a wonderful personality and is great at interviewing people. At the beginning of our time together, she told a story that was very encouraging to me, and at least a part of that story should be encouraging to many homeschoolers as well.

She and her husband homeschooled their children, and although they are both focused on the arts, their youngest son, Simon, was focused on science. They used my high school curriculum for science, but they also read my book, Reasonable Faith: The Scientific Case for Christianity together. She says that her son enjoyed the book, and when he went to college, he referenced it in a paper he wrote for one of his science professors, Dr. Collin Thomas. Dr. Thomas requested a copy of the book, and Simon gave him one. He said that he really enjoyed the book, even though he is not a Christian.

Now, of course, that part of the story was encouraging to me, but the rest of the story should be encouraging to many other homeschooling parents. She said that this professor used to feel sorry for homeschooled students…until he started getting them in his college classes. Now he thinks they are better college students than his publicly-schooled students. She interviewed him on her radio show approximately two years ago, and the interview is fascinating. If you have time, I encourage you to listen to it in its entirety. It starts at 15:20 on the recording that is posted on the website.

About That Habitable Planet…

This NASA image represents an artist’s conception of what the first four planets around Gliese 581 were thought to look like in 2010. (click for larger version)

Gliese 581 is a star that exists about 20 light years away from earth. It became important in the astronomy community back in 2005, when a planet (dubbed Gliese 581b) was detected orbiting it.1 Two years later, two more planets (dubbed Gliese 581c and Gliese 581d) were found there.2 Two years after that, a fourth planet (Gliese 581e) was found.3 All of that was interesting, but it didn’t catch much attention outside of the astronomy community.

Then something amazing happened. A year later, Dr. Steven Vogt and his colleagues found two more planets (Gliese 581f and Gliese 581g) orbiting the star. The amazing thing is that one of those planets (Gliese 581g) was found in the habitable zone of the star! What does that mean? If a planet is too close to its star, it will get very hot. If it is too far from its star, it will remain cold. Life as we know it requires a fairly narrow range of temperatures to exist, so if a planet is to host life, it can’t be too close or too far from its star. It must be in a position that is “just right,” and we call that position the habitable zone of the star. Gliese 581g was in that zone, and even more amazing, it had a mass that was only 3.1 times as much as earth’s mass!4

What did that mean? It meant that Vogt and his colleagues had found the first planet that might be enough like earth to support life. Since it was only 3 times as massive as earth, it was expected to be rocky (like earth), and since it was in the habitable zone, it could have the right temperature to support life. Of course, there are lots of other requirements for a planet to be able to support life as we know it, but that was ignored in all the excitement. NASA released an image (shown above) of what the four inner planets orbiting the Gliese 581 might look like. Notice that the most prominent planet is Gliese 581g, and notice how similar it looks to earth. Dr. Vogt said:

Personally, given the ubiquity and propensity of life to flourish wherever it can, I would say, my own personal feeling is that the chances of life on this planet are 100 percent.

I blogged about this planet back in 2010, noting that it might not even exist. Well, it turns out that the latest, in-depth study of Gliese 581 confirms that Gliese 581g, along with Gliese 581d and Gliese 581f, don’t exist.

When it Comes to Temperature, You Might Not Be Able to Trust the Data!

Posted by jlwile on July 8, 2014

Temperatures for the state of Maine from 1901 to a few years before the present, according to the National Climatic Data Center (NCDC).  The two graphs were downloaded at different times and indicate completely different results.

Temperatures for the state of Maine from 1901 to a few years before the present, according to the National Climatic Data Center (NCDC). The two graphs were downloaded at different times and indicate completely different results.

In 2013, certified consultant meteorologist Joseph D’Aleo was putting together a talk and wanted to show a graph that illustrated how the average temperature of the state of Maine had changed over time. He went to the National Oceanic and Atmospheric Administration’s (NOAA) National Climatic Data Center (NCDC) and downloaded the data. As shown in the top graph, the average temperature showed no trend (warming or cooling) for more than 100 years. This year, he was preparing a talk and wanted to update the graph. He went back to NOAA’s NCDC and downloaded the exact same temperature record, including more recent years.

The change was dramatic, as shown in the bottom graph. The data showed a clear warming trend. Was this dramatic changed caused by more recent years added to the new graph? No. It was caused by the old data! Between the times D’Aleo had downloaded the data, the temperatures for some of the previous years had been lowered, and the temperature for some of them had been raised. However, it seems that more of the earlier years were lowered and more of the later years were raised (or lowered less). As a result, the message of the graph had changed remarkably. Where just one year previously, the data showed no warming over the past century, that same data now show a significant warming trend over the exact same time period! As he states:

Does anybody know what the REAL temperature of Maine is/was/is supposed to be? I sure as [**BLEEP**] don’t. I don’t think NCDC really does either.

What caused Mr. D’Aleo to share this experience? It was a revelation that started with Steven Goddard (aka Tony Heller).

Flu Shot During Pregnancy Produces Unexpected Benefits

If this woman gets a flu shot, it may produce benefits for her child. (click for credit)

I try to keep up with the medical literature, but a chemist who reads this blog, Dr. Jonathan D. Sarfati, made me aware of a couple of studies that I had missed over the past couple of years. Those two studies led me to a third study, and when all three of them are put together, they make a strong case for pregnant women getting the flu shot. I know there is a lot of misinformation out there related to the flu shot, but the evidence makes it clear that the shot is not only safe but also very beneficial, especially for pregnant women.

The first study Dr. Sarfati sent me was published in The American Journal of Public Health back in 2012. The authors used used Ontario’s birth record database (called BORN) to analyze more than 55,000 single-child births that took place in Canada during what the authors call “the 2009–2010 H1N1 pandemic.” They specifically looked at which mothers got the H1N1 flu vaccine. They found that 42% of the mothers did get the vaccine, while the rest did not. They also found that the mothers who received the vaccine were 28% less likely to deliver before their full term and 19% less likely to have a child with a low birth weight. The most striking finding, however, was that mothers who got the vaccine were 34% less likely to have a stillborn child.1

Now this study was specifically focused on a time that health-care officials labelled as a pandemic. Does the flu shot offer the same benefits to the children of pregnant women during non-pandemic flu seasons? Another Canadian study indicates that it does. That study looked at a different database (one in Nova Scotia) for births that occurred from November 1, 2010 to March 31, 2012. There were more than 12,000 births during that time period, and only 19% of the mothers in the group had the flu shot. Nevertheless, they were 25% less likely to give birth to preterm infants and 27% less likely to give birth to infants with low birth weights. Unfortunately, only live births were considered in the analysis, so the risk of stillborn infants was not addressed.2

These two studies together make a very strong case that for the sake of their unborn children, pregnant women should get the flu shot. The other study that Dr. Sarfati sent me was a bit less conclusive (in my opinion), but it does suggest a link between the flu shot and autism. However, it’s not the link anti-vaccination advocates are looking for.
