A "bionic" leg designed for people who have lost a lower leg is undergoing clinical trials sponsored by the US Army. The researchers hope the leg will be able to learn the patient's nerve signal patterns and be able to move in response to the patient's own muscles and nerves.

Could electronic components made from human blood be the key to creating cyborg interfaces? Circuitry that links human tissues and nerve cells directly to an electronic device, such as a robotic limb or artificial eye might one day be possible thanks to the development of biological components.

The immune system recognizes and neutralizes or destroys toxins and foreign pathogens that have gained access to the body. Autoimmune diseases result when the system attacks the body's own tissues instead. One of the most common examples is multiple sclerosis (MS). MS is a serious condition in which nerve-cell projections, or axons, in the brain and the spinal cord are destroyed as a result of misdirected inflammatory reactions. It is often characterized by an unpredictable course, with periods of remission being interrupted by episodes of relapse.
