Whale Flippers Inspire Aeronautical Engineers

Have you seen the bumpy flippers on humpback whales, you know, the species whose males serenade their mates?  Don’t laugh.  Scientists have found that the ungainly flippers actually have superior lift, less drag, and are less susceptible to stalling.  Engineers are imitating the whale flippers for advanced aircraft and helicopter rotors, reports EurekAlert from studies […]

Search for Evolutionary Trade-Offs Comes Up Empty

Husbands and wives know a lot about trade-offs, but according to Darwinian theory, all living things are in a constant tug-of-war between competing interests.  In evolutionary terms, a trade-off is a compromise between competing forces of natural selection.  For instance, “Simultaneously obtaining enough food to grow and reproduce while trying not to become someone else’s […]

Fossil Hummingbird, Arthropod Look Modern

Science announced that a rare hummingbird fossil has been found in Germany and, though assumed to be 30 million years old, is indistinguishable from living New-World hummingbirds.  This upsets the standard theory that hummingbirds evolved in the New World only.  Writing in the May 7 issue,1 discoverer Gerald Mayr said, I report on tiny skeletons […]

Moose Muzzle: A Nose for News

Curious about the enigmatic nose structure of the moose, two researchers picked up moose roadkill and decided to study those large, comical Bullwinkle faces, reports Nature.1  Lincoln Tim writes, The moose, Alces alces, is a member of the deer family, but its nasal apparatus is unlike that of any of its relatives.  The apparatus overhangs […]

How Birds Calibrate Their Navigating Maps

Three researchers tracked birds in the wild and concluded that “night-flying thrushes set their course using a magnetic compass, which they calibrate to the setting sun before takeoff each evening.”  The team of three captured thrushes in Illinois and attached small radio transmitters to them, then followed their flight for up to 1100 kilometers.  By […]

Underground Rodents Have Better Eyes Than Darwin Predicted

European scientists looked into the eyes of African mole-rats, expecting to find retinas that had deteriorated due to disuse in the underground, lightless environment.  What they found were several surprises that “call for a revision of our current views on the visual system of subterranean mammals,” reports a Max Planck Society press release.     […]

Science Reporters Stretch the Truth on Limb Evolution Claim

Item: some fragments of bone were found from a road cut in Pennsylvania.  Conclusion: Darwinian evolution from slime to humans has been demonstrated again.  Sound far fetched?  Not if you are a science reporter for a typical news organization; this is common practice.     The bone this time is a humerus of a presumed […]

Sea Genes Multiply

A potential paradigm-shifting discovery has been made in the doldrums of the Sargasso Sea: there are many more genes in plankton than expected.  Craig Venter’s Celera team sampled the genetic content of microbes off the Bermuda coast, and in 1500 liters of surface seawater, found 1.5 million new genes.  Falkowski and de Vargas, writing about […]

Validating a Just-So Story: How the Lizard Got Its Horns

As if smarting from criticisms that evolutionists trade in stories instead of evidence, Utah State biologists Kevin Young and Edmund Brodie, Jr and son decided to test an instance of natural selection.  Their subject was the horned lizard of the southwestern United States, the misnamed “horny toad” kids like to catch.  Many descriptions of evolutionary […]

Animals Are “Overengineered” for Navigation

Animals outshine us in many ways, but one capability that should humble us is animal navigation.  From spiders to mice, from birds to bees, the ability of animals to find their way around is truly astonishing, and James L. Gould of Princeton has raised our awareness of just how astonishing in a short article in […]

Do Birds of a Feather Demonstrate Parallel Evolution?

A puzzling phenomenon emerges from evolutionary considerations of bird plumage coloration and patterning.  Hopi E. Hoekstra and Trevor Price describe the problem in the March 19 issue of Science1 and provide examples: The pages of any bird guide reveal a spectacular diversity of colors and color patterns.  Although color patterns vary within species, often they […]

Butterflies in Amber Stun Discoverers

New Scientist reports that exquisitely-preserved butterflies have been found in amber from the Dominican Republic.  “It was just incredible,” exclaimed a Smithsonian researcher.  It’s no different than if you took a modern day butterfly and put it under a light microscope.”  But this prompted a puzzle: the amber is estimated to be up to 25 […]

Chameleon Tongue Beats Jet Aircraft

Did you know a chameleon’s tongue is so fast as it shoots out toward its prey, it reaches 50 G’s – five times faster than a fighter jet can accelerate?  Science Now describes how the chameleon does it.  Scientists only recently found out the secret with high-speed photography and careful examination of the tongue structure, […]

Respect the Conch Shell

Engineers and materials scientists seem to never run out of examples in nature that should fill us with awe.  In the Feb. 19 issue of Nature,1 Rosamund Daw brings our attention to the construction ability of the conch shell: Giant conches are seldom treated with the respect they deserve.  Their impressive shells are prized as […]

Birds Are Memory Champs

We humans lose our keys and often can’t remember the location of half a dozen identical items.  “Maybe it takes a bird brain to find the car keys,” teases Susan Milius in the cover story of the Feb. 14 issue of Science News.1  Ornithologists have been intrigued with how birds remember where they stash their […]
