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, ...

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 ...

Most people don’t spend a lot of time thinking about how a fungus reproduces, let alone about what the process might look like. But here you can see a network of soil fungus, with a reproductive spore ...

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 ...

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 ...

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 ...

While this group of colorful neurons was grown in a dish from stem cells, in the body neurons like this are responsible for sensing pain. There is a specialized subset of sensory neurons called ...

This seemingly red-hot macrophage is one of the key components of the human immune system. These cells identify, engulf, and destroy pathogens and allergens that enter our bodies and clean up cellular ...

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 ...
