First, by “Darwinistic” I mean “atheistic-materialist neo-Darwinist”, which includes the view that even the origin of life can be explained by reference to chance and natural law. As Alan Fox points out, many of those here are “laymen” when it comes to evolutionary biology.  Most of us are not specifically schooled or trained in that arena – by “us”, I mean anyone who is interested in the debate about Darwinian evolution vs ID-inclusive evolution.  I, like many, have informed myself to a moderate degree about Darwinistic claims and the ID argument, but I’m certainly not a professional scientist, nor a philosopher with any formal academic training. IMO, a reasonable layman would be highly skeptical of claims that matter, chance & Read More ›

This is a serious science story, not like this one.

From MSNBC, we learn: “Breathe easier: Oxygen molecules found in deep space: For first time, after nearly 230-year search, they turn up in region of Orion nebula.” Which solves a mystery:

“Oxygen is the third-most-common element in the universe and its molecular form must be abundant in space,” said Bill Danchi, Herschel program scientist at NASA Headquarters in Washington.

So where is it? Read More ›

Let us imagine a strange alien race that sets out to learn about humanity. By chance they have encountered a single Scrabble tile imprinted with the letter “e”. Because these aliens are extremely thorough materialists, they undertake to study the tile as deeply as possible. Not only do they subject it to chemical analysis but, due to their superior technology, they are able to map out the exact position of every wood fiber and ink particle of the tile. After years of effort they create a three dimensional model of the Scrabble tile larger than a football field with all this nano information precisely reproduced and annotated. Read More ›

In “Protein evolution in BIO-Complexity”(Todd’s Blog , April 13, 2011), Todd C. Wood comments on the recent BIO-Complexity paper by Ann Gauger and Doug Axe. He finds their work puzzling because they proceed as biochemists rather than evolutionary biologists, and summarizes: In the larger scheme of things, I am sensing a discouraging pattern to BIO-Complexity publications. As I quoted above, the journal is supposed to be about “testing the scientific merit of the claim that intelligent design (ID) is a credible explanation for life,” which is a great goal. But this is the fifth paper published by BIO-Complexity, and it’s the fifth paper that focuses on perceived inadequacies of evolution. So when are we going to test “the scientific merit of Read More ›

Bioethicist Gregory Kaebnick, Ph.D., has an interesting take on the recently announced synthetic cell created by a team of researchers led by J. Craig Venter at the J. Craig Venter Instititute (JVCI). In a recent article in The Scientist entitled Is the “Synthetic Cell” about Life?, Kaebnick writes:

…the technical accomplishment is not quite what the JCVI press release claimed. It’s hard to see this as a synthetic species, or a synthetic organism, or a synthetic cell; it’s a synthetic genome of Mycoplasma mycoides, which is familiar enough. David Baltimore was closer to the truth when he told the New York Times that the researchers had not created life so much as mimicked it. It might be still more accurate to say that the researchers mimicked one part and borrowed the rest.

The explanation from the Venter camp is that the genome took over the cell, and since the genome is synthetic, therefore the cell is synthetic. But this assumes a strictly top-down control structure that some biologists now question. Why not say instead that the genome and the cell managed to work out their differences and collaborate, or even that the cell adopted the genome (and its identity)? Do we know enough to say which metaphor is most accurate?

Judge Robert W. Sweet has turned the biotech patent industry into turmoil.

See: After Patent on Genes Is Invalidated, Taking Stock By ANDREW POLLACK, March 30, 2010

Although patents are not granted on things found in nature, the DNA being patented had long been considered a chemical that was isolated from, and different from, what was found in nature.

But Judge Sweet ruled that the distinguishing feature of DNA is its information content, its conveyance of the genetic code. And in that regard, he wrote, the isolated DNA “is not markedly different from native DNA as it exists in nature.” . . . Read More ›

Semiotix – Stephen Pain The distinction between “theorising” and “belief” is extremely important because our attitude differs towards them. In a theory the reified concept of the sign does not have an ontological status but an epistemological one. While in belief, the concept has often a clear ontological one. Uexküll believed in his concept of the Bauplan in the same way as Bergson believed in the vital force. The concept of a plan is of course no different from the creationist’s concept of “intelligent design”. Any usage of the Bauplan is further complicated by its ideological usage in The Biological State, Uexküll‘s template for the German State, one that was anti-democratic and in many instances attractive to the Nazi of Read More ›

As recently noted on this site, in his letter to the Boston Globe, Harvard University psychology Professor Steven Pinker began SHAME ON you for publishing two creationist op-eds in two years from the Discovery Institute, a well-funded propaganda factory that aims to sow confusion about evolution. Virtually no scientist takes “intelligent design’’ seriously, and in the famous Dover, Pa., trial in 2005, a federal court ruled that it is religion in disguise. (bold added) Virtually no scientist takes “intelligent design” seriously? There appear to be more than a few in the chemistry/chemical engineering community that do. Kudos to a chemist for alerting me to this. Two weeks before Professor Pinker’s letter, Chemical & Engineering News (July 6th issue, pp 5-6) Read More ›

Back in January I posted this comment to ask what is science’s “rightful place.” Now it seems we’re getting a clearer picture of the answer as far as the President is concerned. Fox News is reporting that President Obama to issue an executive order on Monday that would lift the restrictions on embryonic stem cell research put in place under President Bush.

Regardless of one’s opinion or position on this issue, there are a couple points of concern with respect to this story. First is this comment Read More ›

ScienceDaily reports on an interesting experiment relevant to OOL scenarios.

With the aid of a straightforward experiment, researchers have provided some clues to one of biology’s most complex questions: how ancient organic molecules came together to form the basis of life.

Specifically, this study demonstrated how ancient RNA joined together to reach a biologically relevant length. Read More ›

The other day I made an offhand comment that the chirality problem was nowhere being solved. Yellow Shark was nice enough to provide a link to new research published in November, 2008. Now I was referring to scenarios which could occur in nature, not in lab conditions, and so I contacted some friends to see what they thought and to see if the research was indeed relevant to OOL scenarios.
