    Betzig Boosts Biology with Better Visuals

    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

    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.
