The dream of an eternal body seems to dominate scientific study today. The possibility of building a nerve system from a network of cables, proposed through developments in neuroscience, and the building of metallic muscle systems are two examples of steps that are being taken in that direction. According to some specialists, the future promises the creation of a bionic body, without ties to flesh. In this scenario, every health problem could be solved though metallic implants. There is even a study that explores the possibility of repairing DNA after cell death to assure the eternal youth of cells .

DNA REPAIR

It is discovered that the bacteria Deinococcus radiodurans can be revived after being clinically dead, through the repair of its DNA. If DNA could be copied rapidly and the genome of dead human cells could be reconstructed, then the death of cells could be reversed, and all their organic functions could be restored: protein synthesis, lipids and membranes.

ARTIFICIAL ORGANS

Today efforts continue to design artificial organs that could replace organs that have been damaged or affected by severe diseases .

SCAN OF THE BODY

The images obtained from magnetic resonance imaging (MRI) permit exploration of the body in 360°. The most extensive use of MRI l, however, is in the complete scanning of the brain to obtain a variety of images, which permits doctors to observe both the surface and the inside of the brain. Magnetic resonance imaging is one of the most commonly employed medical techniques for obtaining accurate images of the different organs of the body. Its resolution capability permits even the scanning of tissues.

SELF-HEALING CELLS

The dream of having a body in which there is no degeneration of nerve cells is on its way to becoming a reality. Trials to recreate the nervous system through optical fibres has been performed. These fibres would be used to transmit brain impulses. In the future, the body would be a perfect network of fibres that would be degeneration proof. Any problem linked to the nerve system could be eliminated because the cables would substitute for the nerves.

NANOPARTICLES

A thousand times smaller than a full-stop drawn with the tip of a pencil, the molecule that could defeat cancer without the need for chemotherapy is a carbon polymer. 

BIONIC LIMBS

It has been investigated that an elastic metal could replace natural muscles. The artificial muscular system is 100 times stronger and more resistant than human tissue. If these developments work out, they would provide a way of successfully replacing damaged joints.
