Closer look reveals tubule structure of endoplasmic reticulum

(Phys.org)—A team of researchers from the U.S. and the U.K. has used high-resolution imaging techniques to get a closer look at the endoplasmic reticulum (ET), a cellular organelle, and in so doing, has found that its structure is not made of tiny sheets of materials, as was thought, but is instead composed of tubule structures. In their paper published in the journal Science, the team describes their research and their theories on why the organelles have such a dynamic structure. Mark Ter
