Paralysed man walks again after transplant

A paralysed Bulgarian man can walk again after receiving revolutionary treatment in Poland in a breakthrough hailed by one of the British scientists responsible as "more impressive than a man walking on the Moon". Darek Fidyka was paralysed from the chest down following a knife attack in 2010, but can now walk using a frame after receiving treatment in which nerve cells from his nose were transplanted into his severed spinal column, according to research published in the journal Cell Transplantation on Tuesday.
