Study reveals protein that helps green bush crickets mimic green foliage
From a distance, a green bush cricket (Tettigonia cantans) can easily be mistaken for a plant appendage, and that's exactly the point. Its leafy green hue allows it to blend seamlessly into its surroundings, camouflaging ...
Non-seasonal flu vaccine slides closer to reality
University of Pennsylvania researchers have discovered a right-handed, antiparallel double-helix inside influenza ribonucleoprotein complexes that slides strand-against-strand as the viral polymerase copies RNA, offering ...
Keeping time in cyanobacteria: Scientists discover 'ticking' mechanism driving nature's simplest circadian clock
Researchers from the Institute for Molecular Science (IMS)/SOKENDAI and Kyushu University have uncovered the molecular mechanism that drives the "ticking" of the circadian clock in cyanobacteria.

A conservative defense: Downstream negative feedback loops resist evolutionary blitzes
In football, defense keeps the opposing team in check. A similar strategy is at play inside our cells. Negative feedback loops (NFLs) help regulate how cells respond to signals, for example, dialing down activity when things ...
