Cyborgs: threat or salvation for mankind?

July 4 2006

A nightmare of humanity - the era of the cyborg is approaching. While under the specious guise of helping the suffering. Indeed, the huge number of people with disabilities are waiting for a new generation of prostheses. A real breakthrough in this case exercised Professor Gordon Blann and Dr. Catherine Pendegrass together with their counterparts from the center of biomedical engineering at University College London. They have developed a new type of compound prostheses and human tissue, which allows you to attach various devices directly to human bone.

The essence of the project that is inserted into the bone with a metal pin connector, passing through the skin. Upon request, this connector can dock with any device, most importantly, that they were equipped with a return slot.

A new technology called "intraosseous transkozhny amputating prosthesis. It allows you to securely fasten prosthetic limbs to and as easy to unfasten them.

In the foreseeable future, such prostheses can be combined with the technology of artificial muscles of control by nerves in the affected limb. In this case, the developers of the system ensures no risk of infection in the body. The fact is that after surgery the skin around the pin securely overgrown. Implement this idea scientists have helped the deer, or rather their horns, which grow through the skin.

The first test of new technology on several patients who have lost fingers or phalanges, were successful. Now all the tests for the larger prostheses: for legs and arms. Massive use of technology is expected in a few years.

Meanwhile, Canadian researchers from the University of Alberta argue that managed to create a device that causes the growth of tissue of teeth that are broken or fallen.

They are registered in the U.S. patent for the device whose action is based on the use of low-intensity ultrasound. It turned out that the periodic pulses of ultrasound with certain parameters are a growing teeth. This is the first technology to regenerate dental tissues.

The size of the apparatus does not exceed the value of a pea. Course of treatment lasts for 4 months to twenty minutes every day. It can also help get rid of the distortion of teeth.

Professor Jie Chen, one of the sponsors of the project, said scientists are developing a version of the device for mass production. He hoped that the device will be available within two years.

Initially, the technology tests were conducted on rabbits. The device also allows you to build up the jaw bone, which is to help children with gemifatsialnoy microsomes disease in which one side of the jaw of the child remains underdeveloped relative to another. Typically it can be treated surgically.

Connect the piece of living tissue of the brain with the microchip could researchers from the Max Planck Institute of Biochemistry, led by Peter Fromhertsa. Biologists transplanted thin slice of rat hippocampus on the surface of a special chip.

It is known that in the process of remembering and storing information in mammals is involved several brain regions. Before the information gets to the long-term storage, it is previously "written" in a brain region called the hippocampus.

To study the structure of the hippocampus, the interaction of its hundreds of thousands of cells forming the neural networks and their role in the preservation of information using different methods, including - histological, during which obtained and examined thin slices of tissue of this part of the brain.

Registration activity of a large number of brain cells of mammals was made possible with the use of high-density chips, developed by the company Infineon Technologies. Development of a hybrid system that integrates neural tissue and a semiconductor device can stimulate work on prosthetics brain damage and creating neurocomputers.

For example, in 2004, Thomas DeMars from the University of Florida, created from 25,000 rat neurons and multielektrodnoy lattice bioprotsessor able to manage a computer model of a fighter.
