Transpiration is the evaporation of water from the leaves of plants and trees. The undersides of leaves are dotted with hundreds of tiny openings called stoma. Carbon dioxide enters the leaf through these pores, and water escapes. A mature tree may evaporate hundreds of gallons of water on a warm, dry day. The process cools the vegetation and also allows the internal flow of nutrients. The familiar veins within leaves transmit the water to the stoma. Studies have shown that the branching veins, called a dendrite pattern, are spaced out for maximum water flow. This leaf vein pattern may help design engineers build more efficient irrigation systems.

Many trees do not have vertical capillary tubes for transporting water upward. Instead, a spiral network of capillaries and fibers extend the entire length of the tree. This helical geometry strengthens the tree, allowing a greater flexibility or bending motion in high wind or during heavy weight loads. The spiral pattern is sometimes noticed on the surface of dead trees which have lost their bark.

The search for a solution led McRae, now a biologist at the National Center for Ecological Analysis and Synthesis, to his past life as an electrical engineer. He had a hunch that the way animals travel through a landscape might be similar to how electricity moves across circuits. If that were the case, circuit theory would help explain how genes disperse.

We are all familiar with table salt, or sodium chloride (NaCl). This essential, common compound is ordinarily crystalline and brittle in nature. However, many materials behave strangely on the scale of minute quantities, and salt is no exception. Researchers at Boston College have explored tiny salt samples at close distance using an atomic force microscope.

‘Nature demonstrates how maximum performance can be achieved with minimum energy consumption,’ a Festo spokesman said.
“The life-size bionic birds are hydrodynamic and can turn like real penguins because of the flexible glass fibre rods that control their heads.

Festo has been working intensively on the topic of bionics since the early 90s. In 2006, the Bionic Learning Network was launched – an association of renowned universities, institutes and development companies. Since this time, Festo has been developing and supporting projects and test objects whose basic technical principles are derived from a wide variety of principles found in nature.

Diatoms are microscopic, single-celled algae. They are typically a few microns in diameter, ten times smaller than the width of a human hair. There are many thousands of distinct diatom species known, in both plant and animal varieties. They exist in countless numbers in the sea and are the base of many food webs.

The 2003 Nobel Prize was awarded in part to Peter Agre of Johns Hopkins for his discovery, around 1990, of a membrane protein that allows water to pass through cell walls. The discovery of aquaporin solved a longtime problem in biochemistry.
