UN data shows that over one-third of global food is lost or wasted during production, circulation, and consumption, exacerbating food supply shortages while causing enormous consumption of resources such as land, water, and energy.
Researchers employed single-cell RNA sequencing to map gonadal development in a simultaneous hermaphroditic scallop Argopecten irradians. Their work revealed key cell types and interactions, elucidating communication between germ cells and accessory cells. This finding offers insights into scallop reproduction and potential applications in aquaculture.
