This Bacterium Moves Like a Tank
January 3, 2007
Mark McBride (U of Wisconsin) has been trying for a decade to figure out how a gliding bacterium glides. His conclusion: the microbe has tire treads like a conveyor belt that make it roll over a variety of surfaces, like an all-terrain vehicle. According to a U of Wisconsin press release, the Department […]
Precambrian Pods Promoted to Pleistocene (!)
January 3, 2007
The bulletin of the Geological Society of America started 2007 with a bang. (Geeks sometimes refer to the exclamation point as a “bang”.) It’s not often one sees an exclamation point in the title of a scientific paper, but the bang in one by Donald R. Lowe (Stanford) and Gary R. Byerly (Louisiana State)1 conveys […]
Human Endurance: Is It Evolutionary?
January 2, 2007
Some people are gluttons for punishment. Many a couch potato is probably content to watch an Ironman or Ultramarathon on HDTV from a recliner, but the ones who take part in the grueling endurance contests gaining popularity illustrate some human capabilities scientists are only beginning to understand. Nature1 described one called the Primal Quest adventure […]
In Science and Politics, Expect the Unexpected
December 29, 2006
Two findings reported this month illustrate how science changes. Paradigms and policies can have their scientific underpinnings yanked out from under them, causing both consternation and opportunities for new ways of thinking. Bring back the acid rain: Pick your poison: acid rain or global warming. Acid rain was the bogeyman of the 1980s, leading to […]
Cell Zippers, Linemen and Editors Put on a Show
December 28, 2006
The golden age of cell biology continues. Scientists keep unlocking the secrets of cellular machinery with newer and better techniques. With the curtain rising on a show we could not previously imagine, played out on a stage so small it took centuries of scientific work to even see it, biochemists are discovering amazing tricks that […]
Insects Pester Darwinian Story
December 27, 2006
It’s enough to bug any Darwinian: where did the insects come from? Here are some problems right off the bat sonar: Insects are fantastically diverse. Insects are among the most successful animals. There are no insect fossils earlier than the Devonian (evolutionary date: 410 million years ago). The earliest segmented body plans appeared in the […]
Incredible Stasis in Evolution: What Does It Mean?
December 26, 2006
Quite often in phylogenetic research, evolutionists find examples of extreme conservation of genes or traits. How they explain the lack of change is almost as interesting as the phenomenon itself. Here are two recent examples. Your cousin the shark: Surprise: you have more in common with horn sharks than bony fishes do. Craig Venter’s international […]
Danes Found the Keys to Happiness
December 24, 2006
According to the British Medical Journal, reported EurekAlert, British scientists wanted to find out what makes the Danish so darn happy. “Their hypotheses range from the unlikely (hair colour, genes, food and language) to the more plausible, such as family life, health and a prosperous economy.” Their conclusion? Danes are happier than other Europeans because […]
How Your Brain Conducts Itself at Attention
December 22, 2006
The conductor taps the stand. All the musicians, who had been warming up or conversing with neighbors, suddenly hush and rivet their attention on the conductor. The downbeat comes, and a marvel of coordination comes to life, each skilled player contributing to a unified yet diverse exhibition of harmonious sound. Something like that […]
Plant Pores March to Their Own Beat
December 22, 2006
Plants have pores called stomata that open and close (see 09/13/2006). These gates of the leaf surface provide plant protection from invaders, and allow the transpiration of gases and water vapor in and out, depending on conditions. The stomata of many plants open wide during the day to allow in carbon dioxide, but close at […]
Big Dino Found, But How Did it Eat?
December 21, 2006
A few interesting dinosaur stories came to light this month. I was a Spanish monster: A new giant sauropod has been found in Spain, reported EurekAlert based on a paper in Science.1 Named Turiasaurus riodevensis by the discoverers, it ranks among the largest of dinosaurs and is the first giant sauropod found in Europe, weighing […]
Frozen Storms in Sandstone
December 19, 2006
Impress your friends at the water cooler with this phrase: “hummocky cross-stratification.” Let’s call this mouthful HCS and talk about it. It has a story to tell. HCS is a kind of geological formation characterized by alternating three-dimensional hummocks (convex up) and swales (convex down). Discussed in the geological literature since the 1970s, […]
Crisis in Comet Formation Theories
December 18, 2006
Results from the Stardust mission last week (12/15/2006) are causing quite a stir. Detailed analysis of comet dust particles from Comet Wild 2, published in Science Dec 15, reveal the wrong stuff. Scientists found olivine, pyroxene and osbornite – minerals said to form at high temperatures – instead of the cold volatiles expected for an […]
Are Embryonic Stem Cells a Stepping Stone to Eugenics?
December 16, 2006
In Paris, according to Science Dec. 8, “One cherished French institution has attacked another in a bruising battle over embryonic stem cell research.” The cause of the “Jeremiad” as Science dubbed it, was a Catholic Archbishop’s statement to a French health institute that any research “instrumentalizes the embryo or borders on eugenics.” The “News of […]
Animal Plan IT
December 15, 2006
Imitating animal technology is one of the hottest areas in science. The engineering and information technology (IT) observable in living things continues to astonish scientists and makes engineers want to imitate nature’s designs. Biomimetics is leading to productive, useful discoveries helping solve human problems and leading to a better life for all. Here are some […]

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.
