High-resolution mapping of the actin fusion focus reveals myosin V–dependent formin transport for aster formation

Many processes such as polarized growth and secretion require specific actin networks. In fungi, cell–cell fusion requires cell wall digestion mediated by local secretion of lytic enzymes. In Schizosaccharomyces pombe, the myosin V Myo52 transports enzyme-containing secretory vesicles on the actin fusion focus, an aster-like actin network assembled by the condensate-forming formin Fus1. The fusion […]

The hidden harm from salmon farming

In addition to parasites, pathogens, chemical residues, and other treatments can persist in cages. Fallow sites are expected to undergo complete removal of fish and nets to limit pathogen carryover. Campaigners, however, say the Aird site “continued functioning as a reservoir of disease and flesh-eating lice.” Read: The catch. Unsustainable Abigail Penny, executive director of […]

Doomed ants send a final scent to save their colony

Doomed ants send a final scent to save their colony

Ant societies behave like tightly integrated “superorganisms,” where thousands of individuals work together in a way that resembles the coordinated activity of cells in a body. Researchers at the Institute of Science and Technology Austria (ISTA) have found that terminally ill ant brood release a distinctive odor, similar to the way infected body cells send […]
