A major objective of the Mars 2020 mission is to sample rocks in Jezero crater that may preserve organic matter for later return to Earth. Using an ultraviolet Raman and luminescence spectrometer, the Perseverance rover detected luminescence signals with maximal intensities at 330 to 350 nanometers and 270 to 290 nanometers that were initially reported as consistent with organics. Here, we test the alternative hypothesis that the 330- to 350-nanometer and 270- to 290-nanometer luminescence signals trace Ce in phosphate and silicate defects, respectively.

The effect of these interventions on long-term bladder function remains debated, and voiding symptomatology after VES or CU reversal has been poorly characterized.
Objective: The objective of this study was to examine the prevalence and scope of physician treatment patterns as a surrogate for retention or incontinence symptomatology among PUV patients undergoing primary VA or diversion by VES/CU and determine rates of progression to augmentation.
Objective: The purposes of this pilot study were to compare short-term outcomes of the Perception-Action Approach (P-AA) and standard care based on 5 components of first-choice interventions listed in the congenital muscular torticollis (CMT) clinical practice guideline. Changes in postural alignment, symmetrical use of both sides of the body during movement and play, gross motor development, and behavior observed during therapy were considered.
Methods: Thirty-two participants were enrolled in a 2-group (P-AA and standard care) randomized, single-blind trial with pre-posttest measures.
