Your Body Says: Resolve to Exercise

Even moderate exercise can prevent health risks, an article in Science Daily says.  Want to keep the waist trim?  Reduce the bad cholesterol and triglycerides, and increase your HDLs?  Want to lower your risk of diabetes, heart attack and stroke?  Then get out and walk.  You don’t have to become a jogger or gym addict.  […]

What Keeps Skin Strong? Velcro!

Skin would fall to pieces were it not for velcro-like molecules that bind its cells together.  These molecules, called cadherins, make skin strong but also supple.  Their secret was explained by Ashraf Al-Amoudi of the European Molecular Biology Laboratory, quoted in Live Science.  “The trick is that each cadherin binds twice: once to a molecule […]

Dealing with Light at the Extremes

“Light is the most important variable in our environment,” wrote Edith Widder, a marine biologist.  The inhabitants of two different ecosystems have to deal with either too little or too much.  Let your light so shine:  A thousand meters below the sea surface, all sunlight is extinguished.  Yet for thousands of meters more, creatures live […]

The Brain Evolved!… Didn’t It?

Evolutionary neurologists are so absolutely sure the human brain is a product of evolution from lower primates over millions of years, they are able to talk openly and frankly about problems with the particulars.  But in reading some of their own reviews of current ideas, it is not clear which has been evolving: the brain […]

Developing Ear May Have Tuning Fork

What tunes up an embryo’s ears before it hears its first sound?  A new study suggests that support cells in the cochlea, long thought to be inert, have a role in tuning up the hair cells during development.  Experiments by Dr. Dwight Bergles and a team at Johns Hopkins suggest that cells in a tissue […]

Month-End Close-Out

Sometimes the creation-evolution news comes in too fast.  Here’s a baker’s dozen from the October shelf, lest they go stale; time to start a new batch for November. Charity begins at worldview:  David Cyranoski in Nature (450, 24-25, 10/31/2007) investigated why the level of charitable giving in prosperous Japan is a tenth of that in […]

Inner Ear More Complex than Thought

Another level of complexity has been added to the mystery of hearing.  Scientists at Massachusetts Institute of Technology (MIT) found that another membrane in the cochlea of the inner ear, once thought to be passive, is actively involved in transmitting sound waves to the hair cell receptors.  Their work was published in PNAS.1     […]

Appendix to the Vestigial Organs Story: Whoops, Function Found

The appendix is not just a useless organ left over from our evolutionary past, new research is showing.  According to an Associate Press article (see MSNBC News), this “seemingly useless organ may produce, protect good germs for your gut.”  Scientists at Duke University Medical School believe that the appendix can regenerate the normal bacterial flora […]

Don’t Just Sit There; Evolve

Have you ever wondered why your body doesn’t evolve?  After all, it is kind of like a population of trillions of organisms.  Why shouldn’t it follow the rules of natural selection?  Philip Ball asked this question in News@Nature recently.  “Evolution is usually thought of as something that happens to whole organisms,” he teased.  “But there’s […]

Are You a Glorified Ape?

Evolutionists seem in a bit of a quandary lately.  They are convinced that humans evolved from apes, but cannot deny the large cognitive gaps between humans and the alleged nearest ancestors, the great apes.  It’s not just a matter of IQ.  The social skills, language, reasoning, altruism and empathy humans express have no parallels in […]

Eyes Do Precision Digital Sampling

What is the shutter speed of the eye?  Have you ever considered this question?  After all, the eye functions like a camera in some respects.  Shutterbugs know that shutter speed and aperture are factors in proper exposure.  Most of us know that the iris of the eye controls the aperture, but what controls the shutter […]

Monkeys Prefer the Sound of Silence

Given a choice, chimpanzees choose silence over music.  The Random Samples page in Science1 mentioned experiments by scientists from MIT and Harvard where monkeys were given a choice of booths playing a flute lullaby, a Mozart concerto, techno-rock, and silence.  Between the musical booths, “The monkeys spent an average of about two-thirds of their time […]

Human Variability May Swamp Ancestral Hominid Claims

Here are some things to think about when paleoanthropologists draw inferences from fossils alleged to be human ancestors.  A seven-foot-nine-inch man in Mongolia just married a lady more than two feet shorter (see picture at National Geographic).  And a man with just a narrow rim of brain material inside his skull had no symptoms except […]

Health News that Brings Hope

Why do we never see articles claiming that exercise is bad?  Here are some more reasons to get moving. Work your brain:  Who wouldn’t mind a few more brain cells?  EurekAlert reported research from the Karolinska Institute in Sweden that exercise can stimulate the formation of new brain cells.  They think this helps explain why […]

Our Complex Brains: Lessons from Phrenology

This is your brain on science: it is too complex for simplistic diagrams.  Back in the 19th century, the “science” of phrenology was in full swing.  Phrenologists divided the brain into more than two dozen regions of “mental faculties” that controlled such things as instincts for eating and sex, sensation of color, language ability, and […]
