A new study, published in Nature Communications, highlights the role of a protein called PCAF, which seems to successfully trigger a series of chemical and genetic events that allow nerves to regenerate. When we injected PCAF into mice with damage to their central nervous system, this significantly increased the number of nerve fibres that grew back, indicating that it may be possible to chemically control the regeneration of nerves in the central nervous systems.
South Korean scientists say they have developed the world's first nanorobot that can selectively target and help treat cancer. The robot is guided through the body by genetically engineered bacteria to a tumor where it releases its cargo of cancer fighting drugs.
One million dollar Rex – short for robotic exoskeletons – was built using the most advanced artificial limbs and organs from across the world.
And he shows that from bionic arms and legs to artificial organs, science is beginning to catch up with science fiction in the race to replace body parts with man-made alternatives.
