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 ...

During pregnancy and breastfeeding, milk-producing cells that surround the branching network of ducts in the breast swell to form spherical groups called alveoli. These alveoli are where milk is ...

What am I looking at? These images are a series of 1-millimeter-thick slices from front to back through the brain of a mouse, with ChAT neurons (1) in purple and pyramidal neurons (2) in green. The ...

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 ...

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 ...

Microtubules are composed of a protein called tubulin, which consists of alpha and beta subunits that assemble into large, tube-shaped filaments within the cell. These fibers are dynamic, growing from ...

The protein actin is crucial for one of the last steps in cell division – a process called cytokinesis. At the end of cell division, the two resulting cells separate. Actin filaments form a ring in ...

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 ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

Baker, of the University of Washington School of Medicine, was among three scientists honored by the Royal Swedish Academy of Sciences for his work on computational protein design. He shares the 2024 ...

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 ...
