Rare quadruple-helix DNA found in living human cells with glowing probes

Quadruple-helix DNA. Credit: Imperial College London New probes allow scientists to see four-stranded DNA interacting with molecules inside living human cells, unraveling its role in cellular processes. DNA usually forms the classic double helix shape of two strands wound around each other. While DNA can form some more exotic shapes in test tubes, few are […]

Robot probes the Red Sea’s carbon storage system

By studying the fate of organic carbon in the Red Sea, KAUST researchers hope to refine models that predict the carbon sink capacity of the world’s oceans in the future. Credit: Susann Rossbach Warming waters and oxygen depletion in the Red Sea could slow the flow of organic carbon from the surface into the deep […]
