Reader Project: Calculate the Speed of Plant Package Delivery
September 9, 2005
Get out your pencil and hand calculator. A team of Swedish and French scientists measured the velocity of a message traveling on the intraplant internet (see 08/12/2005, 11/09/2004, 10/04/2004 and 07/13/2001 entries). Publishing in Science,1 they believe they have witnessed a signaling molecule, in the form of a messenger-RNA (mRNA; see yesterday’s entry) moving through […]
Beautifully Engineered: Giant Pterosaur Compared to Aircraft
September 9, 2005
Imagine an “aircraft engineer trying to convert a Eurofighter into a jumbo jet while it was still flying.” That’s how David Martill (U of Portsmouth, UK) described the abilities of a baby pterosaur growing into a large adult, a BBC News story says. Evidence suggests that pterosaurs were capable of flying soon after hatching. Some […]
RNA Research Uncovers a Previously Ignored Universe of Genetic Information
September 8, 2005
A slow revolution is occurring in the study of genetic information. Until recently, the only interesting items in DNA sequences were the genes – the genetic codes for proteins. Since these usually represented only a small fraction of an organism’s genome, it was assumed the rest of the material was “junk DNA” – sequences that […]
Comet Theories Vanish in Puff of Powder
September 7, 2005
They were supposed to be dirty snowballs, those comets, pristine relics from the primordial solar system. They were supposed to be blasting volatile ices from their interiors as they approached the sun. What are they doing with aromatic hydrocarbons, olivine, iron, clays and carbonates? When the Deep Impact probe hit its target July 4, it […]
Controversy is the Fuel of Science, So Teach the Controversy, Educator Says
September 7, 2005
The Albuquerque Journal published a response from Rebecca Keller after admitting misrepresenting her position. She did not claim that intelligent design science is looking toward transcendent beings, but rather is asking scientists to become willing to consider design inferences when the data point in that direction. She clarified the intent of the new science standards […]
Bird Brains: No Evolutionary Pattern in Size
September 7, 2005
A scientist went looking for evolutionary patterns in bird brain size, but his chart shows data all over the map. Fahad Sultan (U of Tuebingen, Germany) measured brains in a wide variety of birds, and published his results in Current Biology.1 How does brain size and design influence the survival chances of a species? A […]
Floored of the Rings: Cassini Baffles Scientists at Saturn
September 6, 2005
For the past few months (02/28/2005), the Cassini spacecraft has had a ringside seat at Saturn, with high inclination orbits that have provided the best viewing angles since orbit insertion last year (07/01/2004). Cassini scored, as it soared around and around the horde of ring particles, and poured its stored data toward waiting scientists at […]
Mars Joins Active Volcano Club
September 6, 2005
Mars may join Earth and Jupiter’s moon Io in having active hot-lava volcanos, says a report on BBC News. A field of smooth volcanic cones near the north pole show no sign of impact craters or wind-blown features, suggesting they could have erupted recently. If so, Mars could still be geologically active. At half the […]
Men Arent Going Extinct Yet
September 3, 2005
Not long ago, evolutionary biologists were predicting the demise of manhood (see 11/01/2001, 03/31/2004). The idea was that the Y chromosome, with no redundant copy (unlike the female’s two X chromosomes, and all others) appeared to be shriveling up and mutating itself out of existence. Now that the chimpanzee genome has been published (see 09/01/2005 […]
How Proteins Build Teeth Like Glass on a Mattress
September 2, 2005
Here’s something to chew on. Tooth enamel is hard, like crystal, but is bound to dentin underneath, which is pliable, like a mattress. Your teeth can last a lifetime only because the ceramic-like enamel is cemented to a foundation of softer dentin, and because both of these materials are built to the right hardness specs […]
Is Intelligent Design the New Cussword?
September 2, 2005
The phrase “intelligent design” is being bandied about everywhere. Pro-Darwin scientists generally put it in quote marks with palpable derision; it has practically sunk to the level of the older cussword, “creationism.” Yet a groundswell of support for I.D. continues not only in America but in other countries. Here are recent events, attacks and counterattacks […]
Chimpanzee Fossil Upsets Early Man Speciation Theory
September 1, 2005
Paleontologists need no longer lament the complete dearth of chimpanzee fossils. Nature announced the discovery of the first fossil chimpanzee teeth. The location, however – the Great Rift Valley in Africa – was unexpected. The discoverers, Sally McBrearty and Nina G. Jablonski,1 explain: There are thousands of fossils of hominins, but no fossil chimpanzee has […]
Chimpanzee Genome Published: Is There a Monkey in Your Genes?
September 1, 2005
Nature’s cover story September 1 is about the publication of the chimpanzee genome. Evolutionists are digging through the data for evidence of human common ancestry. Have they found it? The results, as usual, are mixed: MSNBC News states the situation concisely: “Genome comparison reveals many similarities – and crucial differences.” Here is the gist of […]
Briefly Noted
August 31, 2005
Human Body – You Smell Like a Dog: Bloodhounds, we know, are good at telling the direction of a scent, but it turns out that humans have that ability, too. Researchers at UC Berkeley did experiments with human subjects to see if they could tell which direction a scent came from. Functional MRI (fMRI) was […]
Darwin Debates Attract Rhetoricians, Some Pro, Some Not
August 31, 2005
Nothing like a controversy to get people talking. Some understand the issues and speak with skill and style; some just like to be part of the excitement. Here are samples from the war of the words over evolution: Connect the Dots: Having just read Richard Weikart’s From Darwin to Hitler (02/03/2005), Chuck Colson on BreakPoint […]

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.
