Article describes study which found that persistent, recurring blood oxygen level dependent (BOLD) signals in triangulated rs-fMRI videoframes display previously undetected topological findings, i.e., vortex structures that cover brain activated regions.

Article discusses how, based on recent studies, graphene quantum dots (GQDs) are expected to possess advantageous photothermal properties and facilitate fluorescence image-tracking in the visible and near-infrared (NIR), while surpassing other graphene-based materials in their biocompatibility. The combination of the photothermal and imaging modalities tested in vitro makes the GQDs developed in this work prospective agents for cancer theragnostics.

This article is part of a Focus Issue on the topic of Rubin LSST Survey Strategy Optimization. The motivation, history, and decision-making process of the observing strategy optimization are detailed, giving context to the science-driven proposals and recommendations for the survey strategy included in this Focus Issue.
