Sea cucumbers are found on the floor of all the world’s oceans. Their tubular shape resembles a cucumber taken from the garden. The animals frequent shallow coastal waters and are also found in the deepest ocean. Sea cucumbers, also called sea slugs, are colorful occupants of many salt water aquariums. The sea cucumber has the special ability to change its leathery skin from firm to flabby in just seconds. They tense up their body tissue by linking collagen fibers into a stiff net. When the fibers disconnect, the skin again becomes soft and pliable. Such behavior catches the interest of medical workers, especially brain specialists. Patients with Parkinson’s disease or paralysis can be treated by inserting tiny electrodes in the brain.

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 fossil fuel. However, one challenge is to carry enough natural gas on board the vehicle for practical driving. Large, high pressure cylinders are expensive, bulky, and somewhat hazardous.

Computers have come a long way but they still primitive compared with our own brainpower. Our brains can handle much more information and processing than any supercomputer yet developed. The brain is so far superior to current computers that scientists seek ways to mimic its “wiring” in modern computers.

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 application. Dutch researchers are studying the chemical compounds in human saliva. They find an abundance of simple proteins called histatins that actively fight infection. Also present are compounds that cause epithelium skin cells to close quickly over a wound. Most of us have experienced the benefits of these saliva components. Small cuts inside the mouth tend to heal more rapidly than external injuries, and mouth healing leaves little scaring.

Look closely at many tree and plant leaves and you will see an intricate network of veins. Besides the channels branching outward from a central stem, you may also notice many smaller veins in random directions, connecting with each other in closed loops. This complex arrangement is unlike the simple outward geometry of tree branches and root systems. The structure provides protection for the leaf. Suppose there is damage from disease, insects, or wind so that a vein is broken. Nutrients and water can then take alternate paths across the leaf through adjacent veins. Even the larger, central vein of the leaf can be successfully bypassed. The multiple veins also allow for fluctuations in nutrient loads due to moisture and temperature changes. Similar loop network designs are observed in coral colonies, insect wings, and the blood vessels of our eye.

‘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.

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.

BUILDER BOT: This building robot uses a forklift-style arm to hoist foam bricks onto its back and three-pronged wheel-legs to trek around a construction site. An onboard computer “brain” helps the bot navigate and make building decisions independently.
climb steps, carry small objects, multiples of these mini-robots are able to build ramps, towers, and complex structures.
