Was Archaeopteryx a Biplane?
September 22, 2006
A U of Calgary PhD student thinks Archaeopteryx flew on all fours.  Nick Longrich thinks the early bird had feathers on its legs that gave it additional lift.  The discovery of some Chinese fossil birds with feathers on the legs lends support to his interpretation, he says. “The idea of a multi-winged Archaeopteryx has been […]

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 […]

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 […]

Yoke Up Those Bacteria
September 6, 2006
My, how history repeats itself – often in unexpected ways.  In ancient times, our ancestors got the heavy work done by hitching oxen, horses or slaves (like Samson, see pictures 1 and 2) to a harness and making them turn a grinding wheel.  The same principle is now on the cutting edge of modern applied […]

Grass Shack Makes a Comeback
August 28, 2006
Oh, what a feeling: Toyota Roof Garden wants to replace your roof with grass.  Bill Christensen at Live Science says that the car company’s grass tiles include imbedded irrigation piping, provide good thermal insulation and reflect less urban heat to the atmosphere.  The special grass only needs mowing once a year.  Company website (Japanese): Toyota […]

Birds Excel in Distance, Harmony
August 9, 2006
Bird feats are outstanding.  Two notable cases were announced this week: Air Marathon:  The longest animal migration in the animal kingdom is performed by the sooty shearwater, reported National Geographic News.  They migrate 40,000 miles a year from New Zealand to the North Pacific, in complex figure-eight patterns that touch the coasts of South America, […]

Can Evolution Run in Reverse?
August 7, 2006
Evolutionists in Utah are claiming to have run the evolutionary tape in reverse, says the BBC News: “US researchers have taken a mouse back in time some 500 million years by reversing the process of evolution.”  How can this be?  By engineering its genetic blueprint, they have rebuilt a gene that was present in primitive […]

Bacteria Rule the World – Benevolently
August 2, 2006
We should love bacteria, not annihilate them.  Bacteria are our friends, according to Dianne K. Newman of Caltech:1 As a microbiologist, I’m appalled when I go to buy soap or dishwashing detergent, because these days it’s hard to find anything that doesn’t say ‘antibacterial’ on it…. It’s a commonly held fallacy that all bacteria are […]

Eye Sends Information at Ethernet Rates
July 27, 2006
Neuroscientists from Pennsylvania and New Jersey calculated the information rate of the eye.  Using guinea pigs (real guinea pigs, not humans as guinea pigs), they came up with a number and interpolated it for humans: In the classic “What the frog’s eye tells the frog’s brain,” Lettvin and colleagues showed that different types of retinal […]

Honey More Effective than Antibiotics
July 27, 2006
A good old nature remedy is making a comeback: honey for wounds.  An article on EurekAlert about research at the University of Bonn states that honey is more effective than antibiotics at healing cuts and wounds.  Apparently the ancient Egyptians knew about its healing power.  Honey rejects dead tissue faster, repels bacteria, promotes more rapid […]

Is This Frog Marrow Really 10 Million Years Old?
July 25, 2006
LiveScience reported finding intact bone marrow from fossils of frogs and salamanders.  Without blinking an eye, reporter Ker Than croaked that the marrow is ten million years old.  He compared it with the intact soft tissue and blood cells found in a T. rex specimen last year (see 02/22/2006, 06/03/2005, 03/24/2005), and said, The discovery […]

Bear Tooth DNA Yields New Date Record: 400,000 Years

According to a story posted on Yahoo News, Swedish scientists found intact DNA in a bear tooth claimed to be 400,000 years old.  The team leader remarked, “It is usually hard to find DNA that is older than 100,000 years, and work on fossilized DNA mostly focuses on material that is a few tens of […]

Chinese “Living Fossil” Amphibians Found
July 22, 2006
World Net Daily found a story on People’s Daily Online that 1200 specimens of an amphibian, Hynobiidaes, have been found in southwest China.  The article states, “These are a type of amphibian species around 300 million years old that once used to live in the dinosaur period.” Other news sources have not yet reported this […]

Darwinism Confirmed!  How?  Finch Beaks Got Smaller!
July 14, 2006
Randolph E. Schmid of Associated Press (see ABC News) seems hardly able to contain his excitement.  “Finches on the Galapagos Islands that inspired Charles Darwin to develop the concept of evolution,” he wrote, “are now helping confirm it by evolving.”  This sounds like big news.  How, exactly, are they evolving?  “A medium sized species of […]
