There has been a substantial advancement in molecular biology methods and technologies over the past decade. The current planetary protection (PP) toolkit should be expanded to include these innovative molecular methodologies, with validation targeted for 2026. A technology workshop, hosted by NASA, brought together private industry partners, academics, government agency stakeholders, NASA staff, and contractors to explore the potential of modern molecular techniques for this application. At the Multi-Mission Metagenomics Technology Development Workshop, technical discussions and presentations highlighted the importance of modernizing and supplementing the existing procedures of PP assays. By examining the state of metagenomics and other sophisticated molecular techniques, the workshop sought to develop a validated framework, bolstering the NASA Standard Assay, which is based on bacterial endospores, and to ascertain gaps in knowledge and technology. Workshop participants were tasked with exploring metagenomics' capacity to quickly and thoroughly analyze total nucleic acids and viable microbes on spacecraft surfaces. This would enable the production of specialized and economical microbial reduction strategies for each component of the spacecraft. Workshop participants deemed metagenomics the singular data source capable of effectively informing quantitative microbial risk assessment models, assessing the risks of forward contamination of alien planets and backward contamination with Earth-derived pathogens. Participants voiced unanimous support for a metagenomics workflow, coordinated with rapid targeted quantitative (digital) PCR, as a revolutionary advancement over traditional methods for assessing microbial contamination on spacecraft surfaces. Low biomass sampling, reagent contamination, and inconsistent bioinformatics data analysis were identified by the workshop as pivotal areas demanding technological innovation. In the final analysis, employing metagenomics as an additional tool for NASA's robotic missions will foster significant progress in planetary protection (PP) and offer benefits to future missions hampered by cross-contamination.

Cell-picking technology serves as an essential tool in the realm of cell culturing. While newly created tools allow for the selection of individual cells, they necessitate specialized expertise or supplementary equipment. Video bio-logging A dry powder method, encapsulating single to multiple cells in a >95% aqueous culture medium exceeding 95%, is described in this work. This acts as a robust cell-picking device. The proposed drycells are constructed by the application of a cell suspension to a powder bed of hydrophobic fumed silica nanoparticles through a spraying process. Particles accumulate on the droplet surface, generating a superhydrophobic layer that avoids the dry cells' coming together. Precisely controlling the number of encapsulated cells per drycell relies on adjustment of both the drycell's dimensions and the concentration of the cell suspension. Particularly, normal or cancerous cell pairs can be encapsulated to produce various cell colonies within one drycell. Drycell sorting, according to their size, is accomplished using a sieving procedure. Droplet dimensions can fluctuate from a minimum of one micrometer to a maximum of several hundred micrometers. The drycells' firmness enables easy collection via tweezers; however, centrifugation results in their separation into nanoparticle and cell-suspension layers, allowing for the recyclability of the separated particles. Handling can be accomplished through various techniques, among which are splitting coalescence and inner liquid replacement. The anticipated benefits of the proposed drycells are a substantial enhancement of accessibility and productivity in single-cell analysis.

Clinical array transducers are now being employed in recently developed methods to assess ultrasound backscatter anisotropy. Although these resources offer valuable data, they omit details on the anisotropy of the specimens' microstructural features. A geometric model, referred to as the secant model, is introduced in this work to explain the anisotropic behavior of backscatter coefficients. We analyze the anisotropic properties of the backscatter coefficient's frequency dependence, characterized by the effective size of the scatterers. We assess the model in phantoms containing known scattering sources and within skeletal muscle, a well-documented anisotropic tissue type. Using the secant model, we demonstrate the ability to ascertain the orientation of anisotropic scatterers, to precisely gauge effective scatterer sizes, and to categorize scatterers as either isotropic or anisotropic. Monitoring disease progression and characterizing normal tissue architectures may benefit from the secant model.

To pinpoint variables linked to intra-fractional anatomical fluctuations measured via cone-beam computed tomography (CBCT) during abdominal pediatric radiotherapy, and to evaluate the possibility of surface-guided radiotherapy (SGRT) for tracking these changes.
For 21 abdominal neuroblastoma patients (median age 4 years, ranging from 2 to 19 years), 21 initial CT and 77 weekly CBCT scans were utilized to calculate metrics quantifying gastrointestinal (GI) gas volume variation and the separation of the abdominal wall from the body's contour. Age, sex, feeding tubes, and general anesthesia (GA) were evaluated for their ability to predict anatomical variations. Hepatosplenic T-cell lymphoma In addition, the variability in gastrointestinal gas levels was observed to be correlated with alterations in the distance between the body and abdominal wall, in tandem with simulated SGRT metrics evaluating adjustments in translation and rotation between the CT and CBCT imaging modalities.
Measurements of GI gas volumes across all scans displayed a range of 74.54 ml. The body separation deviated from the planned measurement by 20.07 mm, and the abdominal wall separation by 41.15 mm. Patients with an age below 35 years.
