Seward Rutkove explains how a technique called electrical impedance myography (EIM) can be used to measure the health of muscles. He demonstrates a handheld device that can now perform EIM measurements much more quickly than before.
A new microscopy technique called iPALM has been used to reveal structures within cells. Fluorescent labels have been attached to integrins, proteins that cells use to attach to surfaces. The yellow and red regions depict areas where the cell has used integrins to attach to a glass surface. The blue and purple regions are networks of integrins inside a cell.
