The program honors the contributions and service of Hanna Holborn Gray, an HHMI trustee for nearly three decades and a former president of the University of Chicago. During her tenure, the Institute ...

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 ...

In this zebrafish liver, the blood vessels glitter in gold and the bile ducts gleam in neon blue. This image highlights the close relationship between the circulatory system and the cells of the liver ...

Some adult neurons have projections that are amazingly long – thousands of times the length of their cell bodies in some cases. This means that during development, the growing cells need to be able to ...

This cross section through the head of a jumping spider shows off the interior structure of four of its eight eyes. Jumping spiders have the most acute vision of any terrestrial invertebrate. In fact, ...

This may look like a giant supernova in space, but it’s actually a microscopic image of cytoskeletal proteins and DNA in the metaphase stage of cell division. You can see two of the main proteins that ...

Beauty is all around us. It is everywhere our eyes can see – in the breathtaking majesty of snowcapped mountains, in the tranquil shores of tropical beaches, and in the faces of those we love. But ...

Igor Siwanowicz is a research scientist at HHMI’s Janelia Research Campus. He earned his PhD at the Max Planck Institute in Germany in structural biochemistry, but his love for animals and nature, as ...

What criteria or characteristics would you use to group living things versus nonliving things? Scientists have grappled with this question for years, and the debate is still ongoing in the scientific ...

Take a visual journey through some of the major concepts in biology. These pathways to discovery were created by educators to help users explore various biological concepts. We would like to extend a ...

This video presents a kaleidoscope of colors within brain tissue, each of which represents a different protein within the tissue. The video was created using an innovative microscopy technique called ...
