The discovery was made by a group of scientists from polymers and biologists from the University of Massachusetts Amherst have developed what they call “Geckskin”, an adhesive inspired by the power of gecko feet.

The Incredible feet have been studied because of its ease of grip, explained the journal Science by the news of the new glue dry, exceeding the adhesion of the reptile.

Nanotechnology has been commissioned to enter this world from the feet of geckos and found that the adhesion of geckos is transmitted by electricity generated by millions of “hairs” microscopic, perfectly aligned.

It is noteworthy that the species of geckos are small, scaly creatures that live in temperate and tropical areas worldwide.

In the soles of the feet have pads that allow them to climb smooth vertical and even transit through the roof of the house with ease.

These skills are well known among people who live in temperate climates, where several species of geckos often wander inside homes, as pets to camouflage among the furniture.

The stern was the worst sufferer by the loss and the passing of the years that have left an unrecognizable converted into mass of iron, which makes the work of experts in analyzing the wreck.

The Titanic was traveling from the British port of Southampton to New York collided with an iceberg on the fourth day of its voyage, which opened a large crack across the bow and the ship broke in two as it sank.
