Another Impact Theory for Permian Extinction Proposed
May 13, 2004
Richard Kerr was very cautious in his announcement in Science1 about a new claim about an asteroid impact near Australia causing the Permian Extinction. He went to lengths to point out that the evidence is not clear, and that many other scientists disagree. After describing the “proposed” impact site, he cautioned: Not so fast, say […]
Montana Schools Not Allowed to Question Darwinism
May 13, 2004
“Objective origins” is against the law in Darby, Montana (see 02/27/2004 headline). A policy change proposed by a local minister would have encouraged students to “analyze scientific strengths and weaknesses of existing scientific theories, including the theory of evolution.” It didn’t lose because of a vote on the policy, or because of the threats of […]
Geological Column, Rev. 2004-a
May 13, 2004
The geological column is not “set in stone,” John Whitfield discovered as he investigated the work of the International Commission on Stratigraphy (ICS), which is releasing a revised column this summer. “Silurian, Devonian, Triassic: the names seem as solid and permanent as rocks themselves. But in fact,” he cautions in his report in Nature,1 “like […]
Male Imparts More to Embryo than Just DNA
May 12, 2004
A team of biologists have confirmed that male sperm RNAs are delivered to the oocyte along with the DNA. Specifically, paternal messenger RNAs are delivered to the egg. These might influence development and put the male’s imprint on the developing zygote. Writing in Nature,1 the researchers speculate what the finding means: Why should spermatozoa messenger […]
Whale Flippers Inspire Aeronautical Engineers
May 11, 2004
Have you seen the bumpy flippers on humpback whales, you know, the species whose males serenade their mates? Don’t laugh. Scientists have found that the ungainly flippers actually have superior lift, less drag, and are less susceptible to stalling. Engineers are imitating the whale flippers for advanced aircraft and helicopter rotors, reports EurekAlert from studies […]
Search for Evolutionary Trade-Offs Comes Up Empty
May 11, 2004
Husbands and wives know a lot about trade-offs, but according to Darwinian theory, all living things are in a constant tug-of-war between competing interests. In evolutionary terms, a trade-off is a compromise between competing forces of natural selection. For instance, “Simultaneously obtaining enough food to grow and reproduce while trying not to become someone else’s […]
Former Junk DNA Now Considered Essential
May 10, 2004
The term “junk DNA” seems to be fading with each new discovery. Helen Pearson, reporting for Nature Science Update, leads with the line “‘Junk’ DNA reveals vital role: Inscrutable genetic sequences seem indispensable.” They don’t know what it does yet, but the assumption is it must be important for evolution to hang onto it for […]
Searchers in the Dark Over Dark Matter
May 10, 2004
No sooner had Sean Carroll published his essay in Nature1 that dark matter proves how insignificant we are, that Geoff Brumfiel tells us in Nature Science Update that researchers can’t find the stuff. The Cryogenic Dark Matter Search II is four times more sensitive than previous searches, but came up empty. Carroll had just reiterated […]
Botulinum Toxin Deactivated by One Slight Change
May 10, 2004
A researcher at Brookhaven National Laboratory mutated a botulinum enzyme by just one amino acid, and abolished its toxicity. The mutation, a change from a glutamate to a glutamine at one position, increased the distance from a zinc atom to a water molecule by 0.6 angstrom, less than one tenth of a billionth of a […]
Caves Are Made by Bacteria
May 10, 2004
Caves seem like archetypes of slow, gradual, ancient processes. Tourists have long been told that caves form slowly over many tens or hundreds of thousands of years by the slow dissolution of limestone by weak carbonic acid in water carried down from surface rainfall. That explanation took a dramatic turn in the 1970s when scientists […]
Virus: Like DNA in a Hard Plastic Shell
May 7, 2004
A European team of biophysicists studied the mechanical properties of a virus and found the shell, made of protein, to act like hard plastic. Writing in PNAS,1 they described the coat of a bacteriophage they studied: The protective proteinaceous shells (capsids) of viruses are striking examples of biological materials engineering. These highly regular, self-assembled, nanometer-sized […]
Hot Jupiter! Exoplanets Found Very Close to Stars
May 7, 2004
Two examples of Jupiter-size planets have been found by the European Southern Observatory. They are so close to their parent stars, they orbit in less than two earth-days each. Mercury would be 17 times farther out than one of them. They belong to a new class of exoplanets scientists are terming “hot Jupiters.” A few […]
Fossil Hummingbird, Arthropod Look Modern
May 7, 2004
Science announced that a rare hummingbird fossil has been found in Germany and, though assumed to be 30 million years old, is indistinguishable from living New-World hummingbirds. This upsets the standard theory that hummingbirds evolved in the New World only. Writing in the May 7 issue,1 discoverer Gerald Mayr said, I report on tiny skeletons […]
Science Bashes I.D.
May 7, 2004
The Intelligent Design movement took another lashing by the journal Science,1 in the form of three book reviews by Steve Olson, a Washington DC area science writer. Olsen reviewed one pro-ID book, Darwin, Design and Public Education by John Angus Campbell and Stephen C. Meyer, and two anti-ID books, God, the Devil and Darwin by […]
Feathered Dinosaur Exhibit Raises Doubts
May 6, 2004
Can you trust those fossils on display in your local museum, the ones showing “Feathered Dinosaurs and the Origin of Flight”? No less than the respected journal Nature1 is concerned they may have been gathered and sold illegally, and are no more trustworthy than the 1999 Archaeoraptor hoax that embarrassed National Geographic magazine. […]

David Coppedge, B.S. Education, B.S. Physics, founded Creation-Evolution Headlines in late 2000 as a way to share science news he was encountering at NASA. It has grown into a highly-trusted source of news and commentary critical of the pro-Darwin consensus, providing analysis of breaking news of interest to creationists and evolutionists, without the Darwin spin. He has authored over 7,000 entries at CEH since its inception.
