On-demand conformation of an artificial cytoskeleton

Peptide nanotubes are tubular-shaped structures formed by the controlled stacking of cyclic peptide components. These hollow biomaterials show inner and outer faces, allowing control over their properties.

Discovery reveals lipid-signaling microdomains in cells

Important signaling molecules called phospholipids are active throughout cells in small compartments called condensates, rather than functioning primarily in cell membranes as previously thought, according to a study from ...

Cell types in the eye have ancient evolutionary origins

Karthik Shekhar and his colleagues raised a few eyebrows as they collected cow and pig eyes from Boston butchers, but those eyes—eventually from 17 separate species, including humans—are providing insights into the evolution ...

Shedding light on health and zombie cells in aging

With age, cells can experience senescence, a state where they stop growing but continue releasing inflammatory and tissue-degrading molecules. When a person is young, the immune system responds and eliminates senescent cells, ...
