Typically, the swirl of stormy weather obscures the cells at the
heart of severe thunderstorms. This uncommonly clear view of an
entire thunderstorm cell, with the top of the growing
cumulonimbus tower topping out at 40,000 feet, reveals many
interesting features, including “fall streaks” of what may be

cloud. Shortly after this photo was taken on May 22, 2011, near
Madison, the storm pelted the Sun Prairie area with large,
damaging hail. The image depicts a cross-section of mouse
skeletal muscle magnified 60 times. Fibers in the tissue are
fluorescently stained for protein synthesis. The green stain
outlines individual fibers. The bright pink/purple fibers are
newly growing muscle fibers showing protein synthesis rates of
these fiber types for the first time. Images like this allow
researchers to [...] To the human eye
