    (This is meant as a light-hearted take on superresolution!) Super-resolution—the process of reconstructing high-resolution images from low-resolution inputs—is a foundational technology in modern computational imaging. From revealing microscopic structures in biomedical scans to clarifying satellite images from orbit, super-resolution techniques serve as critical tools in medicine, science, defense, and digital media. Traditional methods, such as…

    In the vast, seemingly boundless stretches of the open ocean—especially the oligotrophic gyres and high-nutrient, low-chlorophyll (HNLC) regions—life is surprisingly dependent on a microscopic trace metal: iron (Fe). Though abundant in the Earth’s crust, iron is exceedingly scarce in seawater. And yet, it plays an outsized role in marine ecosystems, regulating biological productivity, influencing atmospheric…
