The Aqua MODIS (Moderate resolution Imaging Spectroradiometer) Level-1A (L1A) Geolocation product contains geodetic coordinates, ground elevation, and solar and satellite zenith and azimuth angles for the center of each MODIS 1-km pixel at nadir. These data serve as a companion dataset to the Level-1B calibrated radiances (MYD02) and the higher-level products to enable further processing. These ge

<i>In vivo</i> imaging of dynamic subcellular brain structures is key to understanding several phenomena in neuroscience. However, in the fruit fly, its implementation has been hindered by a trade-off among spatial resolution, speed, photobleaching, phototoxicity, and setup complexity required to access specific target regions of the small brain of Drosophila. Here, we present DrosoScope: a single

Drug-to-antibody ratio and structural integrity represent two critical quality attributes for antibody-drug conjugates and multispecific biologics in development. Intact mass spectrometry analysis of biologics is crucial to understanding the behavior of a new candidate, especially for complex modalities. Sample preparation is relatively robust and easy to reproduce in different laboratories and by

<div><p>Tuberculosis (TB) treatment requires strict adherence over the long course of treatment. To support adherence, we developed the TB Treatment Support Tools (TB-TST), which combines a urine-based lateral flow assay (LFA) with a mobile application for patient education, support, and communication with treatment supporters. In a pragmatic randomized controlled trial participants uploaded image

Air is commonly used as an oxidizer in proton–exchange membrane fuel cells. However, only 20.9% of air is oxygen and approximately 78% is nitrogen gas, which is inert and is often used to isolate oxygen. We report that N₂–phobicity together with confinement–catalysis exponentially increases the power density of H₂–air fuel cells by selectively transporting oxygen from the air
