Male Nipples: Two Views

Is there a beachgoer who has not wondered why men have nipples?  Since Live Science brought it up, let’s use this as a case study on how evolutionists and creationists explain things. The Evolutionist View:  Live Science claims we all start out as females in the womb, and only after about 60 days the testosterone […]

Take Your Flu Pill: Vitamin D

Vitamin D may be a multi-purpose germ fighter.  An article by Janet Roloff in Science News1 gathered evidence from several research labs that strongly suggests this molecule triggers the formation of one of the body’s effective antiviral, antibacterial, antifungal agents: cathelicidin.  In its activated form, vitamin D binds to a short section of DNA called […]

It’s Hard to Break a Bone

People wearing a cast right now may not feel comfortable, but should be thankful it’s hard to break a bone.  Scientists at Max Planck Institute discovered “a novel construction principle at the nanoscale which prevents bones from breaking at excessive force,” making them “nearly unbreakable.”  Because of the way the rigid components of bone tissue […]

Brain Compensates for Eye Movements

Your eyes are continually jumping in little movements called saccades, yet your brain interprets the view as a steady image.  How can that be?  Scientists at the University of Pittsburgh are on the track of finding out “why our shifty eyes don’t drive us crazy.”  They’ve discovered that the signal that sends a command to […]

Intestinal Efficiency Praised

Leave it to a science website to answer those questions one would never ask out loud, or might not really care to know, like “why are feces brown?”  One line jumps out of an explanation at Live Science that is no joke: “Feces are fascinating.  Flush down your initial grade-school scatological silliness and you’ll discover […]

Science Potpourri

Interesting articles from recent issues of Science have piled up in the queue.  These might have made separate entries in CEH if time and space were unlimited. Deep Impact:  The team of the Deep Impact mission to a comet published spectral results in the July 13 issue.  “Emission signatures due to amorphous and crystalline silicates, […]

Stem Cells: Hurry Up and Wait

When will embryonic stem cells produce cures for Parkinson’s disease, multiple sclerosis, paralysis and other maladies these wonder-cells were promised to bring?  Be prepared to wait.  If predictions of leading proponents are accurate, and if California is to be a world leader in stem cell research and clinical trials, even Christopher Reeve would have died […]

Japanese Man Sets Memory Record

Item: a Japanese man, Akira Haraguchi (age 60), quoted pi to 100,000 decimal places, reported Live Science.  It took 16 hours to say the digits from memory.  This broke his personal best of 83,431 set in 1995, and the Guinness record of 42,195, also set in 1995. Incredible feats like this hint at the innate […]

Mars Radiation Would Fry Astronaut Brains

Imagine the first Martian astronauts coming home confused, impaired and demented.  This is the risk from solar radiation on Mars, say a group of NASA medical researchers (see RxPG News).  Among the gravest risks of a manned flight to Mars ranks the possibility that massive amounts of solar and cosmic radiation will decimate the brains […]

Embryonic Stem Cells No Longer Needed?

Two announcements this week may make harvesting embryonic stem cells obsolete.  First, it’s not necessary to kill an embryo to get a stem cell, reported Associated Press (see Fox News) and Live Science.  While this does not solve all the ethical problems, a White House spokeswoman called it “encouraging to see scientists at least making […]

Crossing the Line for Looks That Could Kill

President Bush may have vetoed one stem-cell bill for moral reasons (see Brad Harrub’s report on Apologetics Press), but in other countries where Judeo-Christian values are less prevalent, morality seems a low hurdle in the race to exploit biological resources that promise health, youth, beauty – and money.     With embryonic stem cell research […]

Human Heads Are Shrinking

There’s no correlation between brain size and intelligence, and if anything, brains today have gotten smaller since the days of our Pleistocene ancestors.  That’s the gist of a report on ABC News Australia based on research at the Queensland Institute of Medical Research: “The genes that are thought to have helped humans evolve big brains […]

Bacteria Rule the World – Benevolently

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

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

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 […]
