HOW CAN DRAGONFLIES GLIDE FOR 30 SEC WITHOUT LOSS OF HEIGHT?

Dragonflies are equipped with micro-thin wings that are corrugated and reinforced with pleats to prevent the wings from bending and give a greater lift while gliding.

According to New Scientist, the micro-thin wings of dragonflies are corrugated and reinforced with pleats, which serve a double purpose: to prevent bending and give a more significant lift while gliding.

The creases have cavities between them that create areas of very low drag and help to generate lifting airflows across the wing. The engineering principles used in the hi-tech wing of a dragonfly can assist in the manufacture of spying robots as well as in the monitoring of pollution levels and disaster management.

Wrens are songbirds found in Australia, which are able to learn the language of other neighbors. Researchers taught the birds to recognize two previously unknown sounds to them as distress calls by playing them in conjunction with the wrens' alarm call, which the wrens associated with danger. After three days, the birds run for cover when they heard the strange sound they learned.

Wolf spiders that live in the Arctic tundra enjoy eating the springtails, but spiders lose appetite them during summer the temperatures are warmer. The springtails feed on fungus, which in turn decomposes melting land matter to form form carbon dioxide and methane. The two gases are responsible to global warming, which means that the more wolf spiders feed on alternative food sources the better for global warming.
