Come explore the invisible world of biology through stunning visuals created by scientists and photographers from around the world.

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 is the embryo of a veiled chameleon (Chamaeleo calyptratus) that’s been stained to visualize its developing skeleton. Its bones are red (1), the cartilage is blue (2), and some of its developing ...

Listen carefully, because this is an image of projections called stereocilia that extend from the hair cells in your inner ear. These cells move when sound waves hit your eardrum; the yellow proteins ...

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 ...

Fun fact: The hexagon is the most common shape in nature. The hexagons in this image are in the eye of a dragonfly. Each hexagonal rod, called an ommatidium, contains major structures that have ...

These are cells that line the trachea of a mouse. The blue-gray, rounded cells (1) produce mucus that lines the trachea and helps protect it. The multicolored, hairy-looking cells (2) are specialized ...

This is an image of an aphid on a leaf of a witch hazel plant. The aphid is the blue and red insect in the middle of the frame (1). You can see its stylet (2) – its mouth – poking into the leaf. The ...

What am I looking at? This is the head and upper thorax of a thistle mantis (Blepharopsis mendica). You can see its characteristic striped eyes (1), its antennae (2), its large claw-like front legs (3 ...

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 ...

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 ...

Science only progresses as quickly as it is shared. That is why HHMI promotes open access and early sharing through preprints. At HHMI, we encourage open science practices through our policies, assess ...
