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 ...

Muscles are formed by the merging of many small myoblasts into larger myofibers. This fusion of mononucleated myoblasts with a single nucleus into multinucleated myofibers with multiple nuclei is an ...

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, ...

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 ...

What am I looking at? These images show a single cell in the middle dividing into two so-called daughter cells. The stage of the cell division process represented here is called anaphase. In these ...

It may surprise you to learn that cells have skeletons, too – a cytoskeleton. However, a cell ’s skeleton is not made of bones but of a specific set of proteins that form filaments and fibers within ...

What am I looking at? These are cells derived from monkey kidney tissue, growing in culture. They were filmed at a very slow frame rate overnight, and you are seeing the video played back here at a ...

What am I looking at? This is a single human hepatocyte. Its two nuclei are in blue (1). The other colors in this image are stains of the actin protein and are depth-coded, with red being the closest ...

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 ...

Coronavirus disease 2019 (COVID-19) is a disease caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). These have become household terms since the start of the global COVID-19 ...

Multicellular organisms are a mosaic of different cells, tissues, and systems, each with their own specific function and interactions with other cells within the organism and/or the larger environment ...
