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 ...

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 ...

These spiked spheres enveloped by blue tendrils are pollen grains infected with parasitic fungi. Some evidence suggests that the fungus uses these pollen grains to travel to new locations and spread.

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 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 ...

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 ...

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 ...

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 ...

What am I looking at? This is a colored scanning electron microscopy image of a human red blood cell infected with the parasite that causes malaria. The infected cell is blue (1), and the uninfected ...

While the bright coloration of this red-eyed tree frog doesn’t make the amphibious creature see red, it does provide an eye-catching display for humans who glimpse it in its rainforest habitat. In ...

Cell division is the process of a single cell splitting into two daughter cells, each of which will contain a copy of the parent cell’s DNA. This image showcases three of the major players in the ...
