The complex architecture of their structural elements and compartments is a hallmark eukaryotic cells. creation high resolution models whole cells has been limited by the relatively low conventional light microscopes requirement for ultrathin sections in transmission electron microscopy. We used soft x-ray tomography to study 3D ultrastructural organization unicellular green alga Chlamydomonas reinhardtii at unprecedented spatial resolution. Intact frozen hydrated were imaged using natural...
Abstract We use data from the Transiting Exoplanet Survey Satellite (TESS) to search for, and set limits on, optical near-infrared photometric variability of well-vetted, candidate James Webb Space Telescope (JWST) spectrophotometric standards. Our 37 these standards has revealed measurable periodic in 15 stars. The majority those show that is less than half a percent; however, four stars are observed vary photometrically, minimum maximum flux, by more 1% (the G dwarf HD 38949 three fainter...
