New Graphene-Based System Could Help Us ‘See’ Electrical Signaling in Heart and Nerve Cells

Image - This diagram shows the setup for an imaging method that mapped electrical signals using a sheet of graphene and an infrared laser. The laser was fired through a prism (lower left) onto a sheet of graphene. An electrode was used to send tiny electrical signals into a liquid solution (in cylinder atop the graphene), and a camera (lower right) was used to capture images mapping out these electrical signals.

3-D Imaging Technique Maps Migration of DNA-carrying Material at the Center of Cells

Image - This image shows the skeletonized structure of heterochromatin (red represents a thin region while white represents a thick region), a tightly packed form of DNA, surrounding another form of DNA-carrying material known as euchromatin (dark blue represents a thin region and yellow represent the thickest) in a mouse’s mature nerve cell.
