The mind-boggling jigsaw puzzle of the nuclear pores 

As control units of our cells, nuclei contain and guard our genetic material. Pores in the nuclear membrane form the only gateway in and out of the nucleus, allowing important messenger molecules to pass but blocking dangerous invaders such as pathogens. They thus help the nucleus to communicate with the rest of the cell while protecting the genetic material. Such challenging task requires a complex biological structure that has kept many scientists occupied for over two decades; a jigsaw puzzle with missing pieces that we could now solve to near completion.
