Histones bound to lipid droplets inside cells offer protection against bacteria in flies, and possibly mice, thus suggesting a possible new innate immunity pathway.

Long-lived intermediate states formed by glycoprotein catalysts are an essential part of the process used by influenza virus particles to infect cells.

A cellular motor protein helps to ensure that microtubules are oriented correctly within neuronal dendrites

The eye produces a protein that inhibits the growth of blood vessels in the deep retina, which includes the photoreceptor layer, and disruption of this process can lead to blindness.

Plants implement arithmetic division to optimize use of carbohydrate reserves and thus maintain metabolism and growth at night.

Structural and biochemical analysis of a protein called Ecp6, which is produced by a tomato fungus, reveals how the protein prevents plants from launching an immune response to the chitin in fungal cell walls.

Hundreds of cell growth and stress response genes are controlled by a rare small RNA component of an ancient splicing machinery, providing a raison d'être for its previously unexplained evolutionary conservation.

A key activator of Ras signaling adopts an autoinhibited, dimeric conformation that is activated by membrane and calcium binding.
