With the sorely inadequate supply of donated human organs – from kidneys to livers and lungs to hearts – available in Israel, scientists here have invested years of research into producing artificial tissue for transplant. But until the technique can proceed, a way must be found to create effective arteries, veins and capillaries to supply blood to the artificial tissue.

Multiple sclerosis (MS) is a very cruel neurological disease, usually first appearing during the third, fourth or fifth decade of life – the prime of life – and totally unpredictable. The insulating cover – called myelin – of the axons of nerve cells that carry electrical impulses in the brain and spinal cord is attacked by the body’s immune system, which recognizes it as an “intruder.”

Machines have for centuries worked for humankind, but can they also think for us? It seems they can, and this amazing but potentially frightening development is called artificial (or machine) intelligence (AI). Unlike natural human or animal intelligence, AI devices survey their surroundings and take aim at a target, imitating human learning, problem solving and carrying out other types of cognitive functions.
