Yoke Up Those Bacteria
September 6, 2006
My, how history repeats itself – often in unexpected ways.  In ancient times, our ancestors got the heavy work done by hitching oxen, horses or slaves (like Samson, see pictures 1 and 2) to a harness and making them turn a grinding wheel.  The same principle is now on the cutting edge of modern applied […]

Another Flagellum Excites Scientists
September 1, 2006
“The bacterial flagellar motor excites considerable interest because of the ordered expression of its genes, its regulated self-assembly, the complex interactions of its many proteins, and its startling mechanical abilities,” begins a paper in Nature by three Caltech scientists.1  They performed electron cryotomography imaging on the flagella of Triponema primita, a different critter with a […]

Quote: Cell Factory
August 28, 2006
From CalTech Engineering & Science (LXIX:2, August 2006), “Cellular CAT Scans” by Douglas L. Smith, an article about electron cryotomography imaging of cellular components.  Smith does not mention evolution.  His opening paragraph is reminiscent of Darwin’s Black Box: A cell isn’t merely a bag of enzymes sloshing around in a thick soup of cytoplasm.  According […]

Early Oxygen Fuels Fire in OOL Camp
August 25, 2006
Live Science reported a new claim about oxygen on the early earth appearing far earlier than usually assumed.  A Penn State astrobiologist is claiming that uniformly high oxygen levels existed on earth 3.8 billion years ago, a billion years before previous estimates.     Oxygen’s presence on Earth has been typically inferred from sulfur isotope […]

Origin of Left-Handed Proteins Solved?
August 24, 2006
As noted in prior entries here (09/06/2003, 11/19/2004) and in our online book, the origin of left-hand proteins is recognized as one of the most formidable challenges to naturalistic origin-of-life research.  Occasionally researchers develop lab techniques for getting slight excesses of one hand over the other.  Astrobiologists agree, however, that 100% purity in a protein […]

Darwinists Whack I.D. with Reckless Abandon
August 21, 2006
For professionals assumed to be logical, factual, and devoted to reason, scientists and journalists can get pretty emotional, depending on the subject.  One such subject that really rankles some of them is intelligent design.  Here are some recent salvos from the war of the words: Hotz shots:  From the LA Times, Robert Lee Hotz wrote, […]

Review:  Lehigh Prof Critiques ID Colleague in Science Wars
August 21, 2006
Dr. Steven Goldman (Lehigh University) has produced a series of lectures for The Teaching Company entitled Science Wars: What Scientists Know and How They Know It.  CEH highly recommends this series for its wealth of historical background applied to an intriguing question: what is the nature of truth claims in science?  To what extent do […]

Stellar Habitable Zones: Don’t Forget the Sunscreen
August 15, 2006
Astronomers concerned with the origin of life on earth have long thought about the “habitable zone” (sometimes called continuously habitable zone, or CHZ) of our solar system.  They’ve discussed this aerobee-shaped zone around our sun – or any star – mainly in terms of locations where the temperature would permit water to exist as a […]

National Crisis: USA Ranks Nearly Last in Evolution Belief!
August 11, 2006
Eugenie Scott and colleagues at the National Center for Science Education presented findings of a survey on acceptance of evolution, and found that the USA trails far behind European countries – second from last only to Turkey.  In 20 years, acceptance of evolution dropped from 45 to 40 percent, but firm rejection of evolution also […]

Cosmologists Dragged Kicking and Screaming to the Anthropic Principle
August 11, 2006
Those who view science as a dispassionate, logical pursuit of the truth should savor the emotions in two articles by Tom Siegfried about cosmology in Science this week.1,2  He reported on the passionate rivalry between theoretical physicists who embrace superstring theory as the eventual “theory of everything” and those who oppose it because of its […]

Ten Years Later: Mars Rock Was a Useful Lie
August 6, 2006
Almost nobody believes any more that the Martian meteorite ALH84001 contained evidence of life, but the iconic rock launched the science of astrobiology (see 04/17/2006).  So said Matt Crenson for AP (see Space.com and Chron.com) on the tenth anniversary of the highly-publicized NASA announcement that purported to show bacteria-like fossils, magnetites and PAHs thought to […]

How Useful Is Evolutionary Theory to Biology?
August 4, 2006
A favorite quote by evolutionists is the line by Theodosius Dobzhansky, “Nothing in biology makes sense except in the light of evolution.”  Why, then, do so many biological papers fail to mention evolution at all?  Indeed, many employ design language, sometimes with a sense of awe.  Here are more recent examples in which the E […]

Team Returns Pseudogene to Junkpile to Counter ID Claim
August 3, 2006
An earlier claim that a pseudogene has a function (see 05/01/2003 story) has been debunked by a team of scientists reporting in PNAS.1  Their reanalysis of the claim made in 2003 “invalidates the data upon which the pseudogene trans-regulation model is based and therefore strongly supports the view that mammalian pseudogenes are evolutionary relics.”  The […]

More Reasons You Wouldn’t Want to Live on Mars
August 2, 2006
Electric charges in dust devils on Mars may generate toxic chemicals, says a report on Space.com (see also later story posted on National Geographic News). According to two recent reports in Astrobiology journal, “Small dust devils and planet-wide storms – combined with static electricity – may lead to the formation of hydrogen peroxide and other […]

Kansas Evolution Battle Heats Up Again

Update 08/02/2006: According to a news report on Live Science, conservatives have lost their majority in the primary election for seats on the state school board.  Details are reported by the Lawrence Journal-World.  The winners are gloating that this is a great day for Kansas, said Science Now, but ended by noting that the issue […]
