Computer Model Claims Lucy Walked Upright
July 20, 2002
A computer robot model of the gait of Australopithecus afarensis (aka, Lucy), reported in the BBC News, suggests that she walked upright.  This is partly on the skeletal structure of the foot and the distance between the Laetoli footprints preserved in fossil ash, where are claimed to date from the same time period Lucy lived.  […]

Depressed Kerry Supporters Find New Cause: Fight Creationism
July 20, 2002
A grass-roots group of Virginia liberal Democrats has found a new cause to lift them out of their depression after John Kerry’s defeat last fall, according to a Washington Post article reprinted by MSNBC News: “Keep Virginia evolving.”  Their chosen mission is to defend evolution from intrusions by the intelligent design movement and conservative Republicans […]

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 […]

Only Atheists Need Apply
July 20, 2002
51; He’s a Christian, yes, but he is also a leading American scientist and a harsh critic of intelligent design.  He supports research on embryonic stem cells and upholds Darwin’s theory of evolution completely.  That’s not enough to get Francis Collins off the hook with the scientific establishment.  Both Nature and Science expressed “serious misgivings” […]

“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 […]

A “Completely Different Slant” on Solar System Formation
July 20, 2002
51; “Did great balls of fire form the planets?” New Scientist asks.  A new theory “challenges the notion that the solar system started out as a placid sea of dust motes which simply clumped together to form planets.” If accepted, it “puts a completely different slant on what happened in the early solar system in […]

Mutating Evolution Into Design
July 20, 2002
51; The word evolve gets used in funny ways.  As Paul Nelson has noted, it often becomes a Designer substitute.  Look how an article in New Scientist employed it: Could a 3D printer help to create in minutes what nature took millions of years to evolve – the perfect insect wing? Tiny robotic insects would […]

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 […]

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 […]

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 […]

Amazing Animals on Parade
June 20, 2002
You have to admire animals.  They have tricks humans still need to learn, and possess technologies that engineers are striving to imitate. Spiders:  Don’t let the black widow scare you; it’s only a picture on Science Daily.  Scientists are amazed at how these animals produce one of the best dragline silks in spiderdom.  It is […]

Hiding Comets Out of Bounds
June 20, 2002
51; There’s a new theory floating around about where most of the comets came from: other stars.  For many years, astronomers hid them in an unobservable region called the Oort cloud that was assumed to be partly a remnant of the sun’s primordial disk, and material that was ejected outward.  Now, according to the BBC […]

Fishing for Darwinian Stories
June 20, 2002
51; Stickleback fish can learn from each other where the best food sources are.  This proves you brain’s remarkable learning abilities have their roots in fish heads, according to science news sources this week.  Science Daily said the findings by UK scientists “show that the cognitive mechanisms underlying cumulative cultural evolution may be more prevalent […]

Sunshine Is for Health
June 20, 2002
51; The old wisdom: stay out of the sun.  The new wisdom: your life could depend on getting sunshine: about 10-15 minutes of exposure three times a week.     Science Daily reported that Vitamin D, produced in the skin by exposure to sunlight, provides more health to the body than previously thought.  Health professionals […]

Peppered Moths Are Back
May 20, 2002
51; One might think that past embarrassments about the peppered moth as evidence for evolution would keep evolutionists reluctant to mention them.  A team from the University of Liverpool either didn’t get the message, or shed all reluctance anyway.  They published a new paper about Biston betularia in Science,1 calling the moth story “a textbook […]
