Submarine Engineers Admire Penguins

An ocean engineer from MIT, Franz Hover, says “we never miss marveling at them,” speaking of penguins.  In the cover story of Science News,1 the submarine designer elaborates: Under the power and guidance of its versatile flippers, a penguin can move through the water faster than 10 miles per hour, turn almost instantaneously, and leap […]

Cooing Doves Set Muscle Speed Record

The dove: a symbol of peace, innocence, love, and gentleness, right?  Its cooing call is a soothing song to nature lovers.  Yet hidden in the throat of the dove is one of the fastest-acting muscles in the animal kingdom, report Elemans et al. in the Sept. 9 issue of Nature.1  The cooing song contains a […]

Darwin’s Finches: Researchers Tweak the Beak

Every once in awhile, a new angle on Darwin’s finches (an icon of evolution) appears in print.  Peter and Rosemary Grant, who have devoted their life to studying everything possible about these related species of birds that inhabit the Galápagos Islands – only to find that evolutionary changes are reversible (see 04/26/2002 headline) – have […]

Humans Lose Some, Win Some in Animal Olympics

Imagine humans competing in Olympic events with animals.  Astrobiology Magazine predicts we would lose many events, but excel in others: “In most cases of physical competition, the animals beat us at our own games,” says the website’s staff writer, Dr. David Noever. 100 Meter Sprint:  Cheetah wins the gold at 3 seconds.  Silver goes to […]

So Is Archaeopteryx a Transitional Form, Or Not?

An international team set out to determine if the skull features of Archaeopteryx, the famous fossil bird, indicated whether it was capable of flight.  The answer reported in Nature1 was affirmative: Here we show the reconstruction of the braincase from which we derived endocasts of the brain and inner ear.  These suggest that Archaeopteryx closely […]

Sparrows Do the Long Haul Without Sleep

During their 2600-mile migrations from Southern California to Alaska, white-crowned sparrows fly day and night without sleep for days on end.  Apparently they don’t have to fly on automatic pilot.  Science Now tells about a University of Wisconsin psychiatrist who watched captive sparrows during their migratory period.  The birds seemed alert and in no way […]

Cormorant Eyes Rapidly Refocus in Dives Into Murky Water

You’re hang gliding over a lake, and you spot a fish below.  From your hovering position, you drop into a rapid, steep dive headfirst into the water.  Whoops; your eyes just went out of focus, and you lost your fish in the murky depths.  Too bad you’re not a cormorant.     Cormorants (a kind […]

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 […]

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 […]

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 […]

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 […]

La Brea Tar Pits Trap Scientists

Sid Perkins of Science News dropped in at La Brea Tar Pits in Los Angeles, and got stuck, not in tar, but in the sticky evolutionary interpretations of these world-famous fossil deposits.  This fossil bed, right in one of the ritziest parts of Los Angeles (adjacent to the County Art Museum), Perkins whimsically calls “L.A.’s […]

How Darwinism Produces Job Security

One thing Darwinism has going for it: it provides endless opportunities to research stories that are nearly impossible to prove.     A case in point was provided in the Dec. 18 issue of Nature.1  John R. Hutchinson (Royal Veterinary College, UK), in a News and Views article on bird evolution, reviewed the new angle […]

Creator Lord Jesus Praised at 100th Anniversary of Flight

When the NASA master of ceremonies told the crowd he was very honored to introduce Anne Graham Lotz, daughter of Billy Graham, to give the invocation at today’s 100th Anniversary of Flight celebration at Kitty Hawk, North Carolina, he apparently did not know what he was in for.  Mrs. Lotz gave a forceful, impassioned, politically-incorrect […]
