Neurons Know What to Do

March 27, 2011

Neurons are among the most vital cells in the body: after all, your brain is largely composed of neurons. Neurons are transmission lines of information that keep a body in touch with itself and the world. None of the other body organs would work without neurons. The increasingly powerful tools of microscopy are allowing neuroscientists […]

We Are Filled with Viruses

March 26, 2011

Viruses have a bad connotation. We immediately think of the ones that cause disease: “I’ve got a virus,” you say when feeling under the weather. Actually, you have trillions of them all the time, even in the best of health. A single gram of stool sample can have 10 billion of them! What does that […]

Sensing the World Requires Intelligent Design

March 24, 2011

How do our bodies make sense of the external world? Through our senses, of course; at least they are the entry points of data into the mind. Behind those senses are remarkable mechanisms that we use but do not actively operate. The design in their automatic operations is slowly being revealed with better observing techniques. […]

You Have Electronic Skin

March 7, 2011

Your skin has resistance with memory. That makes it like a memristor, researchers at the University of Oslo are saying. A memristor is a device that remembers the last current it experienced, and varies its resistance accordingly. New Scientist explained what they found: They found that when a negative electrical potential is applied […]

Go to the Cell, Thou Sluggard

March 2, 2011

Solomon ordered the lazy man, Go to the ant, thou sluggard; consider her ways, and be wise (Proverbs 6:6). Today, he would probably tell lazy materialists needing wisdom to consider the cell. Several recent scientific papers and news stories illustrate why materialism faces a stiff challenge from design features found in the fundamental units of […]

Racial Evolution Education Proposed

February 24, 2011

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

February 21, 2011

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

February 11, 2011

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

February 6, 2011

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

January 27, 2011

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

January 25, 2011

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?

January 21, 2011

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

January 19, 2011

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

January 15, 2011

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

December 23, 2010

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 […]
