    Betzig Boosts Biology with Better Visuals

    By Rich McManus

    Nobel laureate Dr. Eric Betzig has turned serial frustration with the tools of microscopy into a career of improvements that have lead to super-resolution instruments. He is convinced that biologists can't understand what they are studying unless they can see live images.

    Sex Chromosomes Can Trade DNA in Two Regions

    By Eric Bock

    The X and Y chromosomes, also known as sex chromosomes, differ greatly from each other. But in two regions, they are practically identical. “We’re interested in studying how the process of evolution shaped the X and the Y chromosome in gene content and expression and how that subsequently affects literally everything else that comes with being a human,” Dr. Melissa Wilson said.

On the Cover

Researchers at the Midwest Cancer Nanotechnology Training Center are developing a blood clot-mimicking patch capable of delivering drugs at an implantation site in a controllable manner. The patch, consisting of drug-releasing microparticles bound to directionally aligned microfibers, was formed through a unique electrospinning/electrospraying process. The image shows the 2-6-micrometer-thick microparticles attached to the 1-micrometer-thick microfibers.
