First Euro-Stegosaur Found
February 4, 2007
A Stegosaurus fossil has been found in Portugal, reported Live Science. Previously this species with its spiked tail and prominent rows of plates on its back was only known from North America. A tooth, some leg bones and part of the backbone have been unearthed. So far, the fossil looks indistinguishable from its North American […]
Darwinists Topple Darwins Tree of Life
February 1, 2007
Darwin’s “Tree of Life” is a myth. It’s based on circular reasoning. It is a pattern imposed on the data, not a fact emerging from the evidence. We should give up the search for a single tree of life (TOL) as a record of the history of life on earth, because it is a “quixotic […]
Cells Perform Sporting Interactions
January 31, 2007
The components of living cells perform such acrobatic moving interactions, one would think they are having fun. Here’s the news from the Wide World of Cellular Sports. Speedway: A news release from Penn Medicine talks about how motor proteins step on the gas and the brakes in their motions around the cell. The announcer from […]
Cell Quality Control Runs a Tight Ship
January 31, 2007
Without the surveillance and rapid response of quality control, cells would collapse and die. Here are some recently-published examples of nanoheroes in action. Plant checkpoints: Picture a child watching the wonder of a seedling breaking through the soil into the light for the first time. Within hours, the ghostly-white stem turns green, and a day […]
The Space Race: Just Staying Alive
January 30, 2007
“Ad astra!” the sci-fi slogan announces with eternal optimism: “To the stars!” Medical doctors and astrobiologists are not sure you would want to stay there long, though. Some recent findings give a dismal picture of the prospects for life – human or bacterial – at least in our solar system, if that can be assumed […]
Dating a Star is Glamorous Only in Theory
January 30, 2007
Hollywood stars may be fickle, but so are great balls of fire in outer space when it comes to understanding them. Some recent examples: Taking the pulse: The Chandra X-ray Observatory wrote a glowing report about a “textbook supernova,” which is a nice pairing of observation and theory. It added this caveat, though, about dating […]
Squid Eye Beats Zeiss
January 29, 2007
A squid whose scientific name means “vampire from hell” wears specs with excellent specs (that’s lenses with excellent specifications, for the pun-challenged). Elisabeth Pennisi in Science reported on a talk given at an Arizona science conference about the vampire squid, whose “lenses are designed for seeing details, even in virtual darkness.” Researchers studying cephalopod eyes […]
Muscles Use Gears, Automatic Transmission
January 28, 2007
Analogies may not be perfect representations of reality, but it must pique the interest of all of us the way Elisabeth Pennisi in Science1 compared muscle to cars and bicycles: One look at a ballerina as she pirouettes and poses drives home the remarkable ability of our muscles to adapt to diverse biomechanical demands. Manny […]
Cell Membrane Has Ticket-Operated Turnstiles
January 27, 2007
Cells are like castles surrounded by walls. A wall without gates, however, would prevent commerce and trap the inhabitants inside. The cell has ingenious gates that control the flow of goods and services through its outer membrane under tight surveillance and quality control. This controlled flow, as opposed to passive diffusion or osmosis, is termed […]
Moon Origins Not Set in Stone
January 26, 2007
The leading theory for the origin of the moon has been for some time now that a massive object hit the Earth, and the debris formed the moon. New Scientist reported one astronomer who doesn’t buy it. “The collision has to be implausibly gentle,” said Peter Noerdlinger to the American Astronomical Society. “You practically need […]
Robot Legs Cant Keep Up With Animals
January 25, 2007
Robot designers are envious of animals. Insects, crabs and lizards leave them in the dust. Alison Abbott in Nature (Jan 18) described the latest attempts to get the bugs out of insect-imitating “biological robots.”1 “Programming a robot to think like an insect is tough,” the subtitle reads, “but it could help breed machines as manoeuvrable […]
Your Body Knows Its Allies at Gut Level
January 24, 2007
How come your body doesn’t fight its good bacteria? It sounds like a question only a scientist or a kid would ask, but think about it. Your body jumps to arms to fight off pathogens, but lets millions of bacteria live in the intestines. These bacteria help you digest your food, but are not “you.” […]
SETI Head Discusses Criteria for Failure
January 24, 2007
When does the Search for Extra-Terrestrial Intelligence (SETI) project decide enough is enough, and close up shop? Seth Shostak, director of the SETI Institute, took up that question on Space.com. He thinks people should realize that this is a much bolder expedition than the classic voyages of discovery by James Cook and Ferdinand Magellan. He […]
Tiny Fish Smell for Miles
January 24, 2007
Fish hatchlings no more than a few millimeters in size are able to find their way home by smell, scientists from James Cook University found. After hatching from a reef, baby fish are often swept out to sea for miles. The scientists were curious how they are able to get back to the particular spot […]
Stardate: Destruction Estimate Was 0.1% Correct
January 23, 2007
According to a press release from JPL’s Spitzer Space Telescope team, the famous Eagle Nebula “Pillars of Creation” are eroding fast. A supernova that was possibly witnessed by humans 1,000 to 2,000 years ago is sending a blast wave at the structures. An earlier supernova that may have occurred 6,000 years ago has probably already […]

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.
