Cells are in constant motion. They package and move molecules around, change the shape and position of their organelles, and much more. A new microscopy method developed by researchers at HHMI’s ...

Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...

Fruit fly eyes have a different structure than ours do, but they serve similar functions: to detect light from the environment and send that information to the brain. The part of the fly’s brain that ...

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 ...

What am I looking at? This is an image of a fluorescently labeled fruit fly ovary, composed of multiple ovariole strands, each containing multiple developing egg chambers. The eggs are dark ...

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 ...

Actin proteins group together to form a network of thin filaments that spread throughout eukaryotic cells. These filaments are involved in giving the cell its structure, allowing the cell to move, and ...

There is an undeniable connection between a pregnant individual and their fetus, an unseen bond that is difficult for anyone who has not experienced it to understand. And here we can see that there is ...

The colorful threads in this image are muscle fibers. This spotted rainbow illustrates a potential gene therapy approach to treating Duchenne muscular dystrophy (DMD) – a rare, debilitating, and fatal ...

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 ...

Imagine going to the dentist with this set of teeth! These are teeth located on a snail’s “tongue,” or radula, also called a rasper, which is constantly licking the ground to scrape up and transport ...
