Ant colonies operate as tightly coordinated “superorganisms” with individual ants working together, much like the cells of a body, to ensure their collective health. Researchers at the Institute of Science and Technology Austria (ISTA) have now discovered that terminally ill ant brood, like infected cells, release an odor signaling their impending death and the risk they pose. This sophisticated early warning system facilitates rapid detection and removal of pathogenic infections. The study was published in Nature Communications.

Within tissues, cells are embedded in complex, three-dimensional structures known as the extracellular matrix. Their biomechanical interactions play a crucial role in numerous biological processes. Scientists at the Max Planck Institute for the Science of Light (MPL) have now developed a novel lab-on-a-chip system based on intelligent hydrogel structures, which enables precise pressure forces to be applied to cellular microenvironments. The recently presented method could find future applications in medical diagnostics for mechanical disorders in living tissues.
