The ability of C1q to bind to a variety of receptors has implications for signaling biology, spinal cord injury and, possibly, the evolution of the complement system.

An intricate stem cell niche boundary formed by finger-like extensions generates asymmetry in stem cell divisions.

In starving yeast exposed to thermal stress, a transient drop in intracellular pH helps to trigger the heat shock response.

Mutant zebrafish exhibit different behaviours depending on the genetic background of the fish they were raised with.

A new zebrafish study identifies compounds that shield ears and kidneys against an anticancer drug.

New evidence that neighboring communities of bonobos hunt different prey species, despite extensive overlaps in where they live and hunt, is difficult to explain without invoking cultural factors.

The pollen tube in a flowering plant grows in a direction that is influenced by the mechanical properties of the stigma papillae and the organization of structures called cortical microtubules inside these cells.

In order to enter a cell, an ammonium ion must first dissociate to form an ammonia molecule and a hydrogen ion (a proton), which then pass through the cell membrane separately and recombine inside.

High-end technical approaches help to untangle the substructure and projection patterns of the cerebellum.

A common rice pest can avoid its natural parasite by settling on plants that smell like they have been damaged by a species of caterpillar.
