Actin proteins assemble into thin, helical filaments that form a network throughout all eukaryotic cells. These filaments play a significant role in cell structure, movement, division, and more. This ...

A typical neuron is composed of three main structures: the cell body, axon, and dendrites. The cell body is where most of the cellular organelles are located, including the nucleus, which contains 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 ...

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 ...

The radiating, kaleidoscopic pattern you see here was once the living glass skeleton – the cell wall – of a single-celled organism called a diatom. These organisms absorb silicon from their ...

This video lets you peek inside the human brain, highlighting the neuronal fibers that enable communication across the brain. This communication is vital to all brain functions, including learning, ...

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 ...

Measure and monitor HHMI’s institutional greenhouse gas emissions at the two campuses we operate and look for strategies on greenhouse gas reduction at both campuses. Harness the tremendous community ...

Every process has a beginning and end, but sometimes the middle segment is the most interesting. This is an image of a neural stem cell in the midst of the process of differentiating into a neuron. In ...

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 ...
