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.

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.

A tsunami is an ocean disturbance resulting from seismic movement of the sea floor. A wave results and moves across the ocean surface at hundreds of miles per hour. In deep water the passing wave may be only a foot or less in height. Approaching the shallow shoreline, however, the wave becomes large with resulting flood danger and destruction.

At first, we strenuously observed crystals of tap water, river water, and lake water. From the tap water we could not get any beautiful crystals. We could not get any beautiful ones from rivers and lakes near big cities, either.

Certain spiders protect their delicately crafted insect nets with a special silk rope that reflects ultraviolet rays. Birds can see the ultraviolet rays and recognize the webs as obstacles they should avoid.
If engineers can reproduce the effect, it might save birds from their occasional accidental suicide runs into glassy buildings. German engineers at Arnold Glas copied the spiders and glazed their Ornilux-brand glass with a web-like pattern of ultraviolet-reflecting coating to save the birds from high-speed headaches.
