Human-Ape Gap Quadruples
December 20, 2002
Remember that old truism that humans and chimpanzees share 98.5% of their genes?  Try 94% instead.  That’s a new estimate by Matthew Hahn (Indiana U) and a team who published in a new online journal, PLoS One.1  J.R. Minkel, writing for Scientific American, said “The 6 percent difference is considerably larger than the commonly cited […]

Cells Find Signal in the Noise
December 20, 2002
Parents at an amusement park know the challenge of picking out their child’s voice, or even hearing their own hollering, in the noise of the crowd.  Yelling won’t help much if the rest of the crowd is yelling also.  Acoustic engineers know that raising the volume while playing back a noisy tape amplifies the noise […]

Evolution As Assumption
December 20, 2002
51; Reasoning requires premises: axioms or truths taken for granted.  Notice the premise of reasoning stated in a recent article on Science Daily: “Because all living organisms inherit their genomes from ancestral genomes, computational biologists at MIT reasoned that they could use modern-day genomes to reconstruct the evolution of ancient microbes.”  They used an evolutionary […]

Evolutionists Reduce Human Ideals to Molecules
November 20, 2002
Two recent stories illustrate the attempt by some evolutionary biologists to reduce complex human behaviors to chance events among molecules. You Are What You Get High On:  Michael Balter in ScienceNow asked, “Did endorphins make us more human?”  Pondering that question is a photo of a chimp and a naked ape (i.e., man) facing opposite […]

Stem Cell Breakthrough
November 20, 2002
Stem cells from skin cells: it’s all over the news – see EurekAlert 1, EurekAlert 2, EurekAlert 3, EurekAlert 4, National Geographic News, BreitBart.com, BBC News 1, BBC News 2, MSNBC and and PhysOrg for sample reports.  Two teams working independently, one in Japan and one in America, were able to tinker with just four […]

Human Genome Project: A “Worthwhile Failure”
November 20, 2002
The Human Genome Project (HGP) was filled with promise.  Walter Gilbert claimed in 1992 that it would bring about “a change in our philosophical understanding of ourselves… one will be able to pull a CD out of one’s pocket and say, ‘Here’s a human being; it’s me!’”  Why does philosopher-biologist Sahotra Sarkar consider that prospect […]

Intelligent Design Put to Good Scientific Use
November 20, 2002
51; Evolutionists try to portray intelligent design as something outside of science that threatens science.  Actually, the techniques of intelligent design are hard at work within science, and have been for some time.  Examples are not hard to find on a variety of fronts. Archaeology:  “The ability to tell the difference between crystals that formed […]

Genes Are Not Telling the Whole Story
October 20, 2002
A growing realization is dawning on geneticists: there is more going on in DNA than previously imagined.  Now that whole genomes are becoming available, scientists are eagerly trying to understand how the genetic code (genotype) produces a full-grown organism (phenotype), like a fruit fly or human.  The interesting stuff in DNA used to be the […]

Subway System Found in Immune Cells
September 20, 2002
The announcement of a “third form of intercellular communication” hit scientists like TNT: tunneling nanotubules, that is.  Science Now reported that “Scientists have found what appears to be a whole new way for immune cells to communicate with one another: long, narrow tubes that enable them to connect and exchange molecules.”  These subway tunnels between […]

Stupid Evolution Quote of the Week:  Let Darwin Take Over
August 20, 2002
Jack Szostak (Harvard Medical Center) wins this week’s prize for a comment in an Associated Press article (see PhysOrg) claiming that scientists will create life in a test tube within 10 years.  Szostak was explaining the process of creating a cell membrane to the reporter: His idea is that once the container is made, if […]

“Genomic Junk” Is Cell’s Air-Traffic Control
July 20, 2002
51; Linc-RNAs (large intervening non-coding RNAs) have been promoted from junk molecules to air traffic controllers.  A mystery about these transcripts of DNA that are not translated into proteins is being explained.     Science Daily reported on work at Beth Israel Deaconess Medical Center (BIDMC) and the Broad Institute that found these RNA molecules […]

Adult Stem Cells Lead Health Progress
July 20, 2002
51; Adult stem cells (AS) and induced pluripotent stem cells from adult tissues (iPS) continue to rack up tallies over embryonic stem cells (ESA).  Do we really need the embryonic variety?  Some continue to say yes, even though the practice of harvesting human embryos creates serious ethical questions for many. Controlling fate:  If you’d rather […]

Harnessing Cellular Machines for Humans
July 20, 2002
The cell is loaded with molecular machines, so why reinvent the wheel?  or the whole truck?  Martin G. L. van den Heuvel and Cees Dekker wrote in Science that engineers ought to put the existing technology to work.1  The biological cell is equipped with a variety of molecular machines that perform complex mechanical tasks such […]

Something from Nothing Dept.: Can a Divide-and-Conquer Strategy Climb Mt. Improbable?
June 20, 2002
Darwinian evolution from the most primitive organisms to the most advanced must have produced huge increases in functional information (see 06/12/2003 entry).  Yet finding specific genetic mechanisms for just how DNA succeeded in “climbing Mt. Improbable,” as Richard Dawkins termed it in his book of the same name, has been daunting.  In a recent paper […]

Media Becoming Ambivalent on How to Spin Evolution
June 20, 2002
Anti-evolutionists remain the whipping boys of science, but some reporters, at least, seem to be waffling on the effectiveness of the torture.  For others, the heat of the battle is apparently wearing them down.  Some even seem to be entertaining treasonous thoughts that the Darwinists are unable or unwilling to provide the promised reinforcements. Chimp […]
