This glacial blue, gold, and red tapestry is a cross section through the junction between the head and the abdomen of a zebrafish. Here we can see the muscles, veins, and surrounding tissue within the ...

Gilliam Fellows become part of a supportive community of scholars. During their tenure, they build bonds with peers at Gilliam annual meetings, increase their scientific knowledge, and gain important ...

Imagine living your life with a 10-foot–long straw fastened to your face, like this acorn weevil does. That protrusion, called a rostrum, is highly useful for the weevil, however, allowing it to feed ...

This furry ring is a compilation of 50 neurons in the fruit fly brain that help the fly navigate. Recent research shows that when the fly changes course, different sections of this ring activate, ...

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries the information contained within DNA to the ribosomes, where the genetic information is synthesized into ...

This bean-shaped structure in hues of purple, red, and green is a sympathetic ganglion from a newborn mouse. Sympathetic ganglia are chains of neurons up and down the spine that help initiate the ...

This vivid chameleon embryo has been stained to highlight the bones and cartilage of its skeleton. You can also see some of its developing internal organs. This vivid chameleon embryo has been stained ...

During pregnancy and breastfeeding, milk-producing cells that surround the branching network of ducts in the breast swell to form spherical groups called alveoli. These alveoli are where milk is ...

Pyramidal neurons are a very common type of neuron in the brain. Their cell bodies have a unique pyramidal shape that is the source of their name. They make up about two-thirds of all neurons in the ...

Confetti mice are very useful in research because they allow scientists to track which cells produce which proteins based on their color under a fluorescent microscope. These mice are particularly ...

Unlike prokaryotic cells, all eukaryotic cells have nuclei. Nuclei house most of a cell’s genetic information – much of it in the form of DNA – making a nucleus a sort of blueprint for building future ...
