Flourescent image showing the curving structure of a mouse eye developing in an embryo.
Princeton University researchers led by Celeste Nelson have discovered a new way to study embryonic organs — using energy. By mapping mitochondria across the space of a developing tissue, they were able to predict where that tissue would fold to create complex shapes. Above, a mouse eye develops, with the magenta dots representing mitochondria. Image courtesy of the researchers

Microscope image of an RSV-infected cell
A microscope image of a cell infected with respiratory syncytial virus that has been treated with an antiviral drug. The drug causes shape changes to the viral condensates (shown in yellow), resulting in a disruption of viral replication. The large black circular structure is the cell’s nucleus.
