Despite risks of infection and reduced fitness, tooth fracture frequency in gray wolves increases rapidly when prey are scarce because they must consume carcasses more completely.

Neurons called lobula columnar cells help fruit flies respond appropriately to specific visual cues, such as those signaling an approaching predator.

The mouse visual system is able to detect small moving objects due to the activity of VG3-amacrine cells, an unusual type of modulatory cell that uses the transmitter glutamate to activate retinal output cells.

The sampling of visual space is not only warped by attention towards locations but also depends on attended features.

A periosteal Bmp2 signaling center couples bone length to bone width during development and must be reactivated by clinical bone anabolic therapies to reduce fracture risk and accelerate fracture repair.

Editors' Summary: This Replication Study has reproduced important parts of the original paper.

Statistics on the frequencies of pi interactions in folded protein structures enable successful prediction of intrinsically disordered protein phase separation, with clear implications for a physical understanding of cellular organization.

High reproductive effort constrains bone tissue response to physical activity-induced mechanical loading.

A computational model for the control of chemotaxis in the Drosophila larva clarifies the link between the peripheral encoding of naturalistic olfactory stimuli and action selection.

A new form of brain plasticity extends the known limits for how much early sensory input can alter the brain.
