Here are two more........although these have been developed before 2014....
The first one is about 3D printing human organs (The company that I work for has developed a kidney printer for Dr. Atala although I think the one in the video is not ours...we have also developed technology to grow replacement body parts in the lab)

This one is the wildest in my opinion.......Angela Belcher and her team at MIT have genetically modified viruses and bacteria to assemble carbon nanotubes and make batteries and solar cells.
