The ability of fireflies to glow in the dark, delights those who have seen these insects in action. It really seems like a special talent. However a recent issue of National Geographic (March 2015) declared about bioluminescence: “Evolving to make light seems to be relatively easy — it has happened independently in at least 40 different lineages.” (p. 84) Just because we find a special talent in a number of very different creatures, does not mean that the talent was easily developed by chance. National Geographic is not aware that this unusual ability is much more reasonably explained as the choice of God, the creator. There are many examples where we can see the problem for evolution of special talents in very different creatures. And the camera eye is an ideal example. Read the rest of this entry »
There are some useful and visually attractive programs available on YouTube. For example, Privileged Species (previously reviewed in Dialogue) at 32 minutes, has already recorded 33,300 views. However for better quality display, a DVD is required which CSAA sells for $15.00 each.
Several years ago CSAA distributed free copies of the DVD Programming of Life which runs 44 minutes and is produced by LaBarge Media (with Don Johnson). We distributed this to high school and university students, teachers, and pastors. This program examines mathematical issues concerning the living cell. In this context, information is a critical feature of living cells. The kind of information required (proscriptive) involves instructions. From that discussion we proceed to protein manufacturing which is illustrated with beautiful graphics. We then learn the essential features of a computer and how the cell demonstrates these capacities. Read the rest of this entry »
During the 1960s and 1970s, improved strains of wheat and rice resulted in a doubling of crop yields. Despite predictions of disaster from some environmentalists, the world continued to feed quickly growing human populations. This green revolution, kick-started by the research of American plant scientist Norman Borlaug and Indian rice geneticist M. S. Swaminathan, provided much higher yielding crops. However for optimum growth, these crops require the widespread application of nitrogen fertilizers and other chemicals. As a byproduct of this practice, a significant amount of fertilizer ends up in natural waterways. As a result, scientists now consider the application of such chemicals as “so last century!” (Nature October 30, 2014 p. S52). The hunt is now on for crops that do not require chemical inputs and yet produce high yields. Read the rest of this entry »
Dr. Paul Nelson is a prominent spokesperson for the creation and intelligent design communities. It was in that capacity that he introduced enthusiastic participants at the 2013 Creation Weekend in Edmonton, to new arguments and exciting information. Read the rest of this entry »
Over the last decade, everything has become digital. We don’t capture images on film anymore, but in digital files. We don’t send letters, we send email messages. We don’t buy books, we download documents to an e-reader. Every organization has a website. Information is at our fingertips, but the whole system is extremely fragile.
The problems with our digital storage technologies are twofold. The data don’t last once they have been laid down and must be transferred to keep them fresh, while the technology for storage and reading keeps changing. An amusing example of this is NASA, which in the early 2000s, found that it was unable to access data from the space program of the 1960s and 1970s. So there they were, scouring internet auction sites to find second hand eight-inch floppy drives which could read their priceless data. Similar events of loss or near loss happen all the time. In 2009 when Yahoo! closed their GeoCities server, a huge amount of data was lost, perhaps “the most amount of history in the shortest amount of time, certainly on purpose, in living memory.” Nobody seemed to notice, but if these had been paper documents which were lost from a library, the outcry would have been anguished indeed. The take home lesson is that as a digital society, we need better systems to store and read data. In view of this, some scientists have turned their attention not to a new system, but to a tried and true system, much better than modern devices. Enter DNA to the discussion.

You have to wonder how a big science project in biology, which involved 32 laboratories from 10 countries and 440 scientists, and which cost $130 million, could be controversial with many other mainstream biologists. The lead articles were published in the journal Nature on September 6, 2012. What could be controversial about that? Well it transpires that many scientists, who were not involved, did not like the initial thinking on which the project was based, how the research was carried out, and how the conclusions were drawn. What certain mainstream scientists particularly did not like was that so many intelligent design and creation scientists were so pleased. Read the rest of this entry »
It is interesting how dinosaur artifacts continue to amaze us. For example, in 1961, petroleum geologist R. L. Liscomb discovered a large bone bed on the banks of the Colville River in Alaska, not far from the Arctic Ocean. Since the bones were not perminieralized (fossilized), he assumed they were recent bison bones. He deposited some in a museum and for twenty years nobody gave the bones another thought. Then somebody noticed that these were Edmontosaurus bones (duckbill dinosaur). In 1985 palaeontologist William A. Clemens reported abundant dinosaur bones at the Liscomb site and in 1987 associate Kyle L. Davies described the condition of the dinosaur bones: “The quality of preservation is remarkable. The bones are stained a dark red brown but otherwise display little permineralization, crushing or distortion.” (J. Paleontology 61 #1 p. 198). Could such bones really be millions of years old as many scientists now supposed?
If bats were prettier to look at, we might appreciate their amazing talents more. The fact is that bats exhibit some astonishing design features which our engineers and technologists really envy. Traditionally scientists have grouped bats according to their food preferences. There are the fruit bats with good eyesight, the insect consuming, echolocating bats and the vampire or blood consuming bats. Further research has revealed how amazingly these animals are designed for their life styles. Such studies have also revealed that the old fashioned ways of categorizing the creatures according to lifestyle and physical appearance do not really work. This has had some serious implications for ideas concerning whether Darwinian evolution could ever work or not. Read the rest of this entry »
CSAA’s featured speaker for Creation Weekend 2011 was well known creation apologist Dr. Jerry Bergman. Large numbers of people came to hear one or more of his lectures and all declared themselves delighted with his genial, non-confrontational manner and his interesting material. In that Dr. Bergman’s area of expertise is biology, chemistry and medical anatomy, the issues he discussed were quite different from the geological topics which we have considered in recent years. This material demonstrated anew that the issue of creation is broad and encompasses all aspects of nature. Read the rest of this entry »
Anybody studying biology today is aware that proteins form the molecular machines that keep the cells of our bodies healthy. But how many students are told that these proteins are actually beautiful? Read the rest of this entry »
An avid fan of spy stories, I have read many which involve an apparently harmless document (like a friendly letter). But the document actually conveys dangerous information if one is provided with the appropriate convention for decoding it. Read the rest of this entry »
The scientist credited with developing a new type of stem cell, says he is very concerned about the process. The ethical problems go far beyond any issues with embryonic stem cells. Read the rest of this entry »
Some people like a good challenge and some don’t. Some people like the challenge of climbing Mount Everest, while others would prefer to stay home. Such people might point out that there are some challenges which are best ignored. There could well be challenges which are just too difficult or time consuming to undertake. For example, in August a team from Cambridge University reported that it took them twenty two years to produce a synthetic version of azadirachtin, a product which India’s neem tree (Azadirachta indica) effortlessly produces in large quantities.

When I was 19, I had a summer job in a hospital laboratory in Sherbrooke, Quebec. The hospital was fairly small, as it served an English community of perhaps 20,000 to 30,000 people in the extended region. Read the rest of this entry »
