Marine biology is the scientific discipline that investigates the biology of organisms inhabiting marine and brackish environments, encompassing molecular to ecosystem scales. It examines physiological, genetic, and behavioral adaptations to saline conditions, pressure, light regimes, and hydrodynamics, as well as population dynamics, trophic interactions, and biogeochemical roles of marine taxa from microbes to megafauna. Marine biologists employ field surveys, experimental manipulations, remote sensing, and omics-based approaches to quantify biodiversity patterns, primary production, nutrient cycling, and responses to natural and anthropogenic stressors, thereby informing ecosystem modeling, conservation strategies, and management of living marine resources.
A team of chemists, microbiologists and ecologists has designed a molecular probe (a molecule designed to detect proteins or DNA inside an organism, for example) that lights up when a sugar is consumed.
