Bacteria Generate Hydrocarbon Reservoirs
September 21, 2006
Ethane and propane have been detected in ocean depths near the Galapagos, reported EurekAlert. These heavy energy-rich hydrocarbons may be widespread in ocean sediments. The authors of a paper in PNAS1 believe it is formed by bacteria metabolizing acetate from organic material in the sediment, and that this “upsets the general belief that hydrocarbons larger […]
Farewell to the Face on Mars A Teachable Moment
September 21, 2006
ESA’s Mars Express orbiter has just sent back pictures of the Cydonia region on Mars. Objects seen in early Viking images of this region resembled a face, a skull and pyramids that gave rise to a cult following on late-night talk shows. NASA always discounted these resemblances as coincidental, and when JPL released higher-resolution photos […]
Cassini Photographs Earth from Saturn, Discovers New Ring
September 19, 2006
A new ring, geysers from a distance, and our home planet from 930 million miles away – these and more wonders are visible in new photos taken by the Cassini spacecraft orbiting Saturn. Now at opposition (facing the sun), the orbiter’s cameras can pick out fainter details in backlighting. Highlights of the three published photos […]
Genetic Toolkit Manages Dangerous Tools with Safety Switch and Lockbox
September 19, 2006
Laymen appreciate scientists who can express complex concepts in everyday terms. Here’s a good example from the Wistar Institute: Around the home, regularly used tools are generally kept close at hand: a can opener in a kitchen drawer, a broom in the hall closet. Less frequently used tools are more likely to be stored in […]
Marine Mimics Found Off Thailand
September 18, 2006
Live Science reported findings from a rich seascape off the coast of Thailand: “Scientists combing through undersea fauna off Indonesia’s Papua province said Monday they had discovered dozens of new species, including a shark that walks on its fins and a shrimp that looks like a praying mantis.” National Geographic posted even more […]
The Trouble with Neanderthals
September 18, 2006
If nothing else, the scientific investigation of Neanderthal Man is valuable for illustrating how fluid scientific opinion can be. Since we found out Sept. 1 that Neanderthal genes may be lurking among us, two more unexpected claims have been made about these wrestler-build members of genus Homo. Hideouts and Holdouts: Some Neanderthals may have lived […]
Whats Inside a Spore? Nanotechnology
September 17, 2006
The spores that are emitted from fungi and ferns are so tiny, the appear like dust in the wind. Who would have ever thought such specks could exhibit nano-technological wonders like scientists have found recently: Evapo-Motors: Scientists at U of Michigan were intrigued by how ferns turn the power of evaporation into launching pads. The […]
Voles Throw Evolutionary Genetics Into Disarray
September 16, 2006
What is it with voles? These little gopher-like furballs with beady eyes, short tails and tiny ears are giving evolutionary geneticists fits. A press release from Purdue University states, “Purdue University research has shown that the vole, a mouselike rodent, is not only the fastest evolving mammal, but also harbors a number of puzzling genetic […]
Record Dino Trove in Mongolia
September 15, 2006
67 dinosaurs in a week: that’s what diggers from Montana State University found in the Gobi Desert in Mongolia. The team effort was led by veteran dinosaurologist Jack Horner. Most skeletons were Psittacosaurs, thought to be predecessors of the horned ceratopsids, like Triceratops. Seeking to understand the developmental biology of dinosaurs, the team was less […]
Ethane Cloud at Titan: Too Little, Too Late?
September 14, 2006
Those following the Titan exploration by Cassini-Huygens have wondered where the ethane went. Oceans of ethane hundreds of meters deep, if not kilometers deep, were predicted but not found, as reported previously (see 04/25/2003 and 10/16/2003 pre-Huygens reports, 01/15/2005 and 01/21/2005 Huygens early results, and 12/05/2005 review; see also New Scientist analysis of the “total […]
Another Rotary Machine Found in Bacteria
September 13, 2006
A molecular “garbage disposer” in the cell membrane bearing some resemblance to the rotating motor ATP synthase has been described in Nature.1 This machine, called AcrB, expels toxins from the cytoplasm through the cell membrane to the outside. Like ATP synthase, it has three active sites at one end where the binding occurs, and it […]
Plant Protection: A Modern Medieval Castle Story
September 13, 2006
Vigilant guards stand at the gates. In times of peace, they let down the drawbridge, and the townspeople carry on their trade. Farmers bring in their crops for the marketplace, and local craftsmen and pedlars keep the local economy bustling. Yet the sentries maintain a watchful eye, aware that numerous interlopers are about. Aliens constantly […]
Do Mammals Depend on Virus Help?
September 12, 2006
Researchers found that sheep depend on a retrovirus to become pregnant. Retroviruses (those that can insert themselves into a genome of a host cell) include the dreaded HIV and generally have a bad reputation. Remnant retroviruses are prevalent in many animal species and have been considered a class of “junk DNA,” having mutated away their […]
Patients in Vegetative State May Be Aware
September 11, 2006
Remember the arguments put forth for why Terry Schiavo should be allowed to die? They revolved around the awareness of those said to be in a persistent vegetative state. Now, researchers reported in Science1 that a patient diagnosed in a vegetative state was aware of what was going on: We used functional magnetic resonance imaging […]
Historian Reveals Isaac Newton as Biblical Economist
September 11, 2006
The image of Isaac Newton as pure mathematician and physicist ignores a big part of his persona, said Georgia Tech Professor Kenneth Knoespel in a press release reported by EurekAlert. Living in an era when alchemy was still considered a serious subject for natural philosophers, Newton viewed alchemical research as part of his Biblical vision […]

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.
