On this episode of The Pulse, brought to you by MDT TV, we are regenerating limbs, building better brain implants, engineering 3D tissue, and measuring consciousness. This episode features:

• Dozens of genes involved in planarian regeneration have been identified and learning more about them could help advance the field of regenerative medicine, and one day, even lead to the growth of human body parts.
• The Journal of Visualized Experiments has published a technique to accommodate two challenges inherent in brain-implantation technology: gauging the property changes that occur during implantation and measuring on a micro-scale.
• Researchers at the Institute of Bioengineering and Nanotechnology have developed a simple method of organizing cells and their microenvironments in hydrogel fibers.
• A tool to peek inside the brain and measure varying levels of consciousness may one day doctors might track consciousness nearly as easily as they check blood pressure.
