Fuel cells are a promising energy conversion technology with high efficiency and environmental benefits. This paper provides a concise review of recent advances in solid oxide fuel cells (SOFCs), focusing on electrode and catalyst materials. It quantitatively compares performance metrics such as power density and polarization resistance to identify optimization pathways. Key technical bottlenecks-particularly durability and high cost-are critically analyzed. The study also outlines the major...

Crassulacean acid metabolism (CAM) is a specialized photosynthetic pathway that enhances water-use efficiency by temporally separating nocturnal CO(2) uptake from daytime decarboxylation and carbon fixation. To uncover the regulatory mechanisms coordinating these temporal dynamics, we generated high-resolution, 48 h time-course transcriptomes for the CAM model Kalanchoe fedtschenkoi under both 12 h/12 h light/dark (LD) cycles and continuous light (LL). A rhythmicity analysis revealed that diel...

CONCLUSIONS: We identified a high number of treatable psychiatric illnesses in the referred parents. Partnerships between pediatric complex care teams and psychiatry services and using virtual care may help with timely and accessible mental health care for this at-risk population. Future research could investigate adherence to and efficacy of treatment recommendations for this caregiver population.

CONCLUSIONS AND RELEVANCE: Actigraphy measures of sleep phase variability and daily activity amplitude were associated with depressive relapse, supporting actigraphy as a potential scalable biomarker to identify high-risk individuals and enable timely, personalized relapse prevention in MDD.

Bergmann glia (BG) are a specialized glial population essential for cerebellar development, yet their developmental timeline and molecular identity in the human cerebellum remain poorly understood. Here, we combined detailed histopathological analysis with spatial transcriptomics and single-nucleus RNA sequencing to generate a developmental atlas of human cerebellar BG. Histology revealed that BG emerge around 11 postconception weeks (PCW), initially serving as a scaffold for Purkinje cells...

Fold switching, where a protein region interconverts between entirely distinct three-dimensional structures, is emerging as vital for certain protein functions. Here, we report a remarkable example in the F7 pyocin, a phage tail-like bactericidal nanomachine. Cryogenic electron microscopy and tomography reveal that a 163-residue segment of the central tail fiber undergoes a dramatic transition-from a trimeric α-helical coiled-coil to a triangular β-prism-upon binding to the bacterial cell...

To probe drug mechanism of action (MOA) and interrogate the genetic architecture of human cells, we carried out isogenic genome-wide CRISPR/Cas9 knockout screens against 310 diverse drugs, bioactive compounds, and stress conditions. Stringent statistical correction for gene knockout fitness defects yielded a large-scale matrix of >12,000 high confidence chemical-genetic interactions (CGIs). This dataset revealed many previously unappreciated off-target effects for well-characterized compounds...
