More Reasons to Enjoy Creation Outdoors

Evidence keeps mounting that exercise is good for almost every body.  It can prevent and alleviate many ailments.  But isn’t that only natural? Low back pain:  Laziness increases the risk of back pain, reported EurekAlert on work from Australia.  Staying in bed shrinks muscles needed to support the back.  So does prolonged inactivity at a […]

More Optical Design in Eye Retina Than Seen Before

For decades, evolutionists have used the vertebrate retina as an example of poor design (dysteleology).  They have mocked how any designer could have been so unintelligent as to get the wiring backwards – with the photoreceptors behind a jumble of light-scattering cells.  Creationists have countered that despite the arrangement, it works well.1  Now, they may […]

Snot Serious: Artificial Nose Works Better with Mucus

What will they think of next?  Designers of electronic noses cannot yet come close to the natural nose in sensitivity.  But in trying to improve their devices, they tried another trick from nature: artificial boogers.  Yes, believe it or snot, adding a layer of synthetic mucus “improved the performance of their electronic nose allowing it […]

Human Adaptation Can Be Rapid

How long does it take for humans to adapt to environmental changes?  Some recent papers investigated this question. Paleface:  If it is assumed that humans started out medium or dark-skinned, how long did it take for Europeans to lose much of that original pigment?  An article in Science April 20 says maybe just 6,000 to […]

Dirt for Physical and Mental Health

Live Science has an article suggesting that exposure to dirt can improve your mood by boosting the immune system.  This is an unexpected twist on the “hygiene hypothesis” that childhood exposure to dirt and animals helps innoculate the body to certain diseases (see 08/02/2006).  Certain bacteria might not only boost the immune system, but also […]

Preprocessed Sound Produces Tone Map in the Brain

Most of us know that our ears involve three domains: the outer ear, the middle ear, and the inner ear.  We learned in school how the eardrum transmits the sound to tiny bones that transmit it to fluid in the cochlea, which stimulates hair cells that send the impulses down the auditory nerve to the […]

Questions to Ask a Reductionist Neurobiologist

Can the totality of the brain be described in terms of its neurons?  Is consciousness an artifact of the movement of signals in the brain?  Can the complexity of the brain be described in terms of its evolutionary history?  Does the hardware define the software that runs on it? Gy�rgy Buzs�ki attempted to address these questions […]

Why Our Voices Are Unique

We can usually recognize friends and acquaintances by their voices.  If we all have the same hardware, though, how is this possible?  The answer is in the vortex.  Sounds sci-fi, but researchers at the University of Cincinnati used knowledge of jet engines to explore the possibility that vortices may help solve the mysteries of the […]

Music Can Make You Smarter

Musical training in childhood can help one develop better language processing skills, reports a news item on EurekAlert.  Scientists at Northwestern University found that English-speaking adults who had musical training were better able to track intonations of Chinese tonal words than those who did not have such training.     The study contradicted an evolutionary […]

Skin Includes Built-In Damage Protection

Ultraviolet radiation that tans skin can also cause skin cancer, right?  Right, but the skin also produces a cancer fighter to come to the rescue, reported EurekAlert.  Scientists at the Dana-Farber cancer institute detected a known cancer fighter named p53 that is produced right under the skin.  Their results, published in Cell (see summary on […]

Evolutionary Theory Not Even Skin Deep

A book on skin just was published – no, not one of those books, but a book on the physiology of human skin.  Nina Jablonski wrote Skin: A Natural History (UC Berkeley, 2006) and Qais Al-Awqati (Columbia U) reviewed it in Science.1  The reviewer noticed that “In its discussion of the human skin, the book’s […]

3 Out of 5 Doctors – Leaves 2

Every once in awhile it’s good to be reminded that yesterday’s nutritional advice can be wrong.  We need to beware of simplistic approaches to health.  For instance, the cliches “If a little is good, more is better” or “it worked for me” can be deadly.  TV commercials are filled with glowing promises for this or […]

Music Out of Range of Darwin’s Instrument

In Science this week,1 Michael Balter reported on a Montreal meeting of the Brain, Music and Sound Research Center (BRAMS).  The center is gaining attention for its renewed interest in the biology of music, and why human beings are so good at this skill with its dubious survival value.  The topic came up about how […]

The Space Race: Just Staying Alive

“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 […]

Muscles Use Gears, Automatic Transmission

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 […]
