Cat's Paw Nebula
The Cat's Paw Nebula, imaged here by NASA's Spitzer Space Telescope using the MIPS and IRAC instruments, is a star-forming region that lies inside the Milky Way galaxy. New stars may heat up the surrounding gas, which can expand to form "bubbles."

MEMOIR
MEMOIR enables the histories of cells to be recorded in their genomes and then read out using microscopy. Here, MEMOIR cells were variably activated, as seen by the bright cyan nuclear fluorescence in some cells. The cells recorded information in response to this signal with the help of a DNA-editing system called CRISPR. This recorded information was then read out using a technique called seqFISH to visualize certain RNA transcripts in the cells (red dots).

Illustration of seven TRAPPIST-1 planets
This illustration shows the seven Earth-size planets of TRAPPIST-1, an exoplanet system about 40 light-years away, based on data current as of February 2018. The image shows the planets' relative sizes but does not represent their orbits to scale. The art highlights possibilities for how the surfaces of these intriguing worlds might look based on their newly calculated properties.

A mouse tibia that has been rendered transparent with Bone CLARITY. Stem cells appear distributed throughout the bone in red. The ability to see bone stem cell behavior is crucial for testing new osteoporosis treatments.
