Evolution of Flight: A Story Looking for Evidence

An evolutionary dogma is that land dinosaurs evolved into flying birds. When the claims are acid-washed with critical analysis, what evidence remains?

Make Like a Dog, Owl, or Beetle: How Biomimetics Will Improve Our Lives

The greatest breakthroughs in health and engineering may be as near as the back yard: 13 more stimulating stories from biomimetics.

Proteins Conduct Electricity

A remarkable finding at the single-molecule level shows a protein can conduct a large amount of electricity.

Venus Flytrap Still Mystifies, Inspires

The Venus flytrap remains one of the most intriguing plants in the world. What makes it snap shut in a tenth of a second? Can we imitate its motion without muscles, wires or batteries?

C. S. Lewis's Views on Evolution, Scientism Clarified

A new book and video clarify the views of C. S. Lewis on science, scientism, and evolution.

Your Senses Awe Scientists

The ear, the eye, the nose, and the mind itself continue to display wondrous capabilities.
