Racial Evolution Education Proposed

Skin color provides a “handy tool for teaching evolution,” says a anthropologist at Penn State.  PhysOrg reported that professor Nina Jablonski believes “The mechanism of evolution can be completely understood from skin color.”  She proposes using the easily-observed trait in humans to teach evolution to students.  “People are really socially aware of skin color, intensely […]

Human Genome Project Supports Adam, Not Darwin

Science magazine last week had a special series of articles on the 10-year anniversary of the Human Genome project.  Most of the articles expanded on how different the findings were from predictions.  The publication of the genome did not identify our evolution; it did not lead to miracle cures.  What it did most of all […]

This Is Your Brain on Bytes

It’s mind-boggling time.  Some recent articles have tried to quantify the information capacity of the eye, the brain, and the world.  Ready?  Think hard. Eye boggle:  Your eyes contain about 120 million rods and 6 million cones each.  If each receptor represents a pixel, that is 2 x 126 million pixels, or 252 megapixels.  And […]

Intelligence as a Cosmic Reality

The “I” in SETI takes “Intelligence” seriously.  It requires that intelligence is a recognizable, quantifiable property of nature.  The origin of intelligence is a question that separates theists from materialists – whether it is a fundamental or emergent property.  Before engaging that question, it might be instructive to see how scientists who are not necessarily […]

Hikers Stay Healthy, Happy, Sharp-minded

A study at the University of Toronto reinforces the growing body of evidence that being active outdoors is good for you.  PhysOrg printed an interview with Guy Faulkner, in the Physical Education faculty at U of Toronto, who shared that exercise not only provides physical benefits; it beats depression and appears to slow the onset […]

Amazing Mammals

As the Superbowl approaches, millions of spectators will enjoy the feats of our own sports heroes.  But what if animals put on games with their capabilities?  Human athletes would find it hard to compete. Swimming:  A polar bear performed a phenomenal feat of endurance swimming, reported the BBC News.  According to a zoologist who observed […]

Has Biomimetics Surpassed Biology?

An article on Science Daily announced an invention that is “Better Than the Human Eye: Tiny Camera With Adjustable Zoom Could Aid Endoscopic Imaging, Robotics, Night Vision.”  While true that human eyes do not have zoom lenses, how does the comparison hold up?     The invention both imitates and surpasses human vision in some […]

Molecules as Traffic Cops

One of the cutting-edge developments in cell biology and genetics is the realization that there are networks of molecules that are regulated by other molecules.  Some molecules stimulate growth while others repress it.  The dynamic interplay between signals, hormones, repressors and other processes somehow leads to “homeostasis” – a dynamic balance that is responsive to […]

The Brain as the Computer Robots Need

A mind is a terrible thing to waste, especially once you realize how incredibly powerful it is.  In some ways it’s like a computer that needs maintenance; in other ways, it is too powerful to describe in machine language.  Here are a few mind matters to mind because it matters: Reboot to clear the ringing:  […]

Brain Synapse Machinery Is Finely Tuned

The New York Times published a brief article on brain facts that is astonishing, when you think about all that goes on in thinking.  Nicholas Wade reported on a new inventory of the proteins involved in the synapses, the key junctions between neurons.  The research team, led by Seth Grant of the Sanger Institute near […]

Are You Too Clean?

You shower, you put on clean clothes, you wash your hands with antibacterial soap, you keep the house spic and span, you work in a clean office – and you set yourself up for disease and depression.  That’s what some scientists are proposing with the “hygiene hypothesis.”  By depriving yourself of access to your bacterial […]

Boggle Your Brain

A new animation of a trip through a brain shows mind-boggling complexity in more detail than ever before.  The animation, posted by freelance journalist Elizabeth A. Moore on CNET News, represents years of work by Stanford University School of Medicine.  Using green fluorescent protein in a mouse brain to light up synapses, and photographing the […]

Windows into the Mind

What would it be like to see things for the first time?  You can watch the reaction on Live Science #1 and Live Science #2.  Blind patients were implanted with a microchip that allowed them, for the first time, to roughly sense the visual input of objects in front of them.  Amazing as it was, […]

Automatic Turnstiles Found in the Cell

One of the things students learn about in high school biology classes is active transport: the ability to control flow through a semi-permeable membrane.  Contrary to osmosis, in which the flow goes naturally from high concentration to low concentration, cell membranes employ active mechanisms to push or pull the molecules through their membranes according to […]

Mind Matters

The conundrum of how reasoning could have emerged by an undirected evolutionary process persists.  Atheists and materialists are convinced that natural selection is up to the task, while theists strongly disagree and use human rationality as evidence for creation by an intelligent source (usually God).  Perhaps a few recent findings can illuminate on the options. […]
