Nematode Preparing to Spit
This is a scanning electron micrograph of a Steinernema carpocapsae nematode; this is what they look like when they are spitting venom into their host.
Toxoplasma Host Cells
This image shows two different Toxoplasma host cells changing their shape to migrate.
Mapping Connections in the Mouse Brain
A section of mouse brain stained to identify individual neurons and all their connections. Each color represents a different DNA barcode.
The Social Brain
A cross-section of a mouse brain reveals some of the regions involved in the choice between social approach and avoidance.
Mouse Spinal Cord
Microscopy of spinal cord sample from a mouse model of neurodegeneration.
This image shows a male sexual polyp of the cnidarian Hydractinia symbiolongicarpus, a species of water-residing animals.
Studying Blood Cell and Vessel Development in Zebrafish
Zebrafish are a useful model for studying the development of blood cells and blood vessels. This image shows blood cells (magenta) in blood vessels (yellow) on the yolk of an anesthetized, 2-day-old, transgenic zebrafish embryo, which is about the size of a grain of rice.
Organ of Corti
An organ of Corti from a one-day-old mouse, showing sensory hair cells in green, supporting cells in purple, and cell nuclei in blue.
Northern Star Coral
Some corals are particularly light-sensitive, making them difficult to image. In this case, darkfield imaging has been used to reveal the non-autofluorescent coral tissue in the Northern Star coral, a species with no intrinsic fluorescence.
Mouse Astrocytes Preparing for Autophagy
This is an image of mouse astrocytes showing the actin cytoskeleton (red) and lysosomes (green). The cells are preparing for autophagy after experiencing osmotic stress.
