This colorscape of tubes and grooves is a cross section through the reproductive region of a fern. Ferns use spores to reproduce and spread, and here we can see these spores (blue/purple) encased in ...

Muscles are formed by the merging of many small myoblasts into larger myofibers. This fusion of mononucleated myoblasts with a single nucleus into multinucleated myofibers with multiple nuclei is an ...

Now why would someone throw paint all over a perfectly good human brain? The good news is that this isn’t a paint splattered brain, but the colors are meaningful. This is a functional magnetic ...

The structures at the bottom of this image that look like scales are actually bundles of muscles just under the skin of a rabbit. This image is a stained cross section taken under polarized light ...

What am I looking at? The blue structure is the stigma (1), the very tip of the pistil of this thale-cress flower. The orange dots are pollen grains (2) that are stuck to the stigma. The pollen grains ...

This time-lapse video shows the development of the nervous system in a fruit fly embryo as it transitions to the larval stage. Fruit flies have a high reproduction rate and a very short gestation ...

These side-by-side time-lapse videos offer a detailed view of how cells move in a growing fruit fly embryo and of how its nervous system develops and organizes. This is a side-by-side time-lapse video ...

We rarely see the cells that help defend us from the microorganisms and debris that can cause sickness. Visible as white spots in the interior of these intestinal villi, however, are immune cells ...

These male stag beetles have developed some impressive mandibles (mouthparts) to win mates. Male stag beetles will battle it out with other males to demonstrate who is the largest and strongest and ...

What am I looking at? This video shows actin at work in a growing intestinal organoid. The video is depth-coded for color, which means that cooler colors like blue and purple are closer to the viewer ...

Beauty is all around us. It is everywhere our eyes can see – in the breathtaking majesty of snowcapped mountains, in the tranquil shores of tropical beaches, and in the faces of those we love. But ...
