Can Networks Design Themselves?
October 4, 2005
A molecular biologist and a physicist at the Weizmann Institute of Science in Israel (see also 09/26/2003) wrote a paper in PNAS1 with an intriguing title: “Spontaneous evolution of modularity and network motifs.”  Can a network arise spontaneously?     Biologists increasingly speak of the interaction of genes, proteins and metabolic processes in terms of […]

Muscle Motor Observed in Action
October 3, 2005
Myosin proteins have been heavily studied in recent years since they are critical to many cellular and tissue functions, including muscle.  According to EurekAlert Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it “walks” along […]

Darwinian Phylogenetic Tools Are Mathematically Flawed
October 1, 2005
Many evolutionists use software tools to construct evolutionary trees from genetic data.  Two mathematicians have just reported in Science1 that several popular “tree-building” algorithms can give misleading results: Markov chain Monte Carlo (MCMC) algorithms play a critical role in the Bayesian approach to phylogenetic inference.  We present a theoretical analysis of the rate of convergence […]

Spider Blood Survives 20 Million Years – So They Say
September 30, 2005
EurekAlert announced, “Spider blood found in 20 million year old fossil.”  Science Daily repeated the story.  The articles even tell how the spider died (it was climbing a tree and was struck on the head by fast-flowing sap).  The BBC News said, “Spider is ‘20 million years old.’” At least they put quotes around the […]

Can a Robot Build Itself?
September 30, 2005
The news media got a load of Joseph Jacobson’s toy robots that could make copies of themselves.  Ker Than on LiveScience, for instance, called these “biological” robots: Inspired by biological systems, scientists have developed miniature robots that can self-assemble using parts that float randomly in their environments.  The robots also know when something is amiss […]

Were Dinosaurs Gasping for Air?
September 29, 2005
A news story on CNN claims that “the air contained only about 10 percent oxygen at the time of the dinosaurs.”  It climbed to 23% by 40 million years ago, then dropped to its current level at 21%, said the researchers.  They feel that the rise of oxygen “almost certainly contributed to evolution of large […]

Another Record Distant Galaxy Found
September 29, 2005
The Spitzer Space Telescope found a “positively gigantic” galaxy at a time the universe was supposedly only 800 million years old – just 5% the assumed age of the universe – according to a press release from Jet Propulsion Lab.  For the galaxy to be this big that far back, it must have “bulked up […]

Scientific Institutions Root for Darwin
September 28, 2005
With the Dover trial in the midst of its first week (09/26/2005), the Goliath fans are sounding off, led by their cheerleaders, Nature, Science and other institutions: Nature had two pieces this week, claiming the Dover trial represents Do or Die for Design.  This editorial ended, “Scientific organizations are well aware of this case’s significance, […]

Do Dead Meteorites Tell Tales?
September 28, 2005
Several researchers lately have claimed that meteorites can tell us the history of our solar system.  How can this be? Messages from Heaven:  Richard Kerr in Science1 reported on work by Strom et al. in the same issue2 that the asteroid belt was the source of the so-called “late heavy bombardment” that is said to […]

Hobbit Update
September 28, 2005
BBC News posted an article updating the story of Homo florensiensis, the so-called “Hobbit Man” miniature-human fossil (see 10/27/2004).  Opponents of the “missing link” interpretation are becoming more ardent in their claim that the fossils represent diseased modern humans with a condition known as microcephaly.  The discoverers are not convinced. Wait for this story to […]

Carl Sagan’s Cosmos Is Back
September 27, 2005
MSNBC News reported that Carl Sagan’s popular 13-part series Cosmos is returning to TV this week, digitally remastered and enhanced with new up-to-date animations.  The 1980 series, which began with its own Agnus Dei invocation “The cosmos is all that is, all that ever was, and all that ever will be,” went far beyond the […]

Rhetoric Heats Up Over Dover IDea
September 26, 2005
Now that the ACLU’s lawsuit in Dover, Pennsylvania has gone to trial, more and more news media are writing about the controversy over intelligent design.  Many seem to think that the school board is trying to replace Darwinism in high school science classrooms with I.D.; actually, the Dover case does not mandate the teaching of […]

Is Archaeology Like SETI, or is SETI Like Religion?
September 24, 2005
Archaeologists have their Rosetta Stone, but so far, SETI investigators have no artifacts.  Still, Douglas Vakoch wrote for Space.com, archaeologists and anthropologists can teach SETI researchers how to prepare for encountering “exotic cultures with strange languages.”     Vakoch recounted the interest in this angle at an anthropology conference last year: One of the best-attended […]

Alternative Gene Splicing May Be Common
September 23, 2005
Scientists at MIT publishing in PNAS1 detected instances of alternative splicing in over 1,000 genes of stem cells.  They also computed possible isoforms of mRNA transcriptions and found 80% of them in the cells.  Not only that, the isoforms (alternatively spliced versions of exons from the same gene) appeared to be functional: “We find that […]

More Indications Neandertals Were Like Us
September 23, 2005
Two more hints that Neandertals were only variants of modern humans have surfaced recently.  British and American researchers publishing in PNAS1 studied tooth enamel growth patterns, and found that “Neandertal tooth growth and, by extension, somatic growth, appears to be encompassed within the modern human range of interpopulation variation.”  This finding was summarized on National […]
