Saliva a wound-healing elixier

This example of a practical design in nature may lack appeal but it is vitally important to our health. A common phrase is to “lick one’s own wounds.” This saying expresses the effort to care for one’s own needs and generally look out for oneself. However, there is a more practical applicati

mimic the dragon fish; put chlorophyll into your eye for higher night vison sensitivity

Many marine creatures produce chemical light in a process called bioluminescence. The typical color produced is blue. One group of deep-sea fish, however, called the Malacosteid family, produce an unusual red color. They are also called dragon-fish or loose-jaws. Other fish cannot see or detect the

ultra-small lab equipment  based on Bladderworts roots

One of the smallest traps in the world is inspiring physicists in studies of fluids. Bladderworts are a type of plant that grows in standing water or wet soil, and sometimes in very rough conditions. A unique aspect of this plant is its underwater roots which include many microscopic bladder-like t

lizard tail for stabilizers

Lizards are some of the most versatile animals on the planet. Geckoes for example can climb straight up walls, even across glass ceilings upside down. Their feet have been studied to learn how to make better adhesives. Now, lizards are the subject of a new investigation which includes the dinosaurs.

flexible eye lens focused by a fluid

The lens in our eye has a special designed feature called accommodation. That is, the lens changes shape, curvature, or focal length to bring images into focus. When we look at a far distant object the lens becomes thinner. For nearby objects the lens thickens and becomes rounder for clear vision.

Intestine - Fuel Tank

This is an unusual example of practical designs found in nature. Automobiles have several new options for fuel including batteries, hydrogen gas, and natural gas. Natural gas is especially attractive because it is in good supply in the U.S., and emits only half the carbon dioxide of conventional fos

A species of North African scorpion does not mind getting sand blasted or whipped by desert winds. While other desert creatures burrow downward for protection, the scorpion scurries in the open and withstands abrasion. Studies reveal that its surface is covered with many hardened, dome-shaped bumps

will our lungs help to reduce carbon dioxid emissions on our planet?

Our hard-working lungs clearly show intelligent planning. Within our lungs, countless tiny air sacks called alveoli exchange gases from the bloodstream, supplying fresh oxygen and removing carbon dioxide. The component membranes which allow separation and passage of the gases are about one thousand
