Solar Wind Irradiation of Methane and Methane-Water Ices: A Molecular Dynamics Approach.

Molecular dynamics simulations were performed to characterize reaction products, resulting from solar wind irradiation, namely, H, of methane and methane-water ices. In our approach, we used seven 0.829 keV H (total energy of 5.

Exploring DNA repair deficient CHO cell response to low dose rate radiation.

Introduction: DNA double-strand breaks (DSBs) induced by ionizing radiation pose a significant threat to genome integrity, necessitating robust repair mechanisms. This study explores the responses of repair-deficient cells to low dose rate (LDR) radiation. Non-homologous end joining (NHEJ) and homologous recombination (HR) repair pathways play pivotal roles in maintaining genomic stability.

Use of historical isoscapes to develop an estuarine nutrient baseline.

Coastal eutrophication is a prevalent threat to the healthy functioning of ecosystems globally. While degraded water quality can be detected by monitoring oxygen, nutrient concentrations, and algal abundance, establishing regulatory guidelines is complicated by a lack of baseline data (e.g.

A chromatin remodelling SWI/SNF subunit, Snr1, regulates neural stem cell determination and differentiation.

Coordinated spatio-temporal regulation of the determination and differentiation of neural stem cells is essential for brain development. Failure to integrate multiple factors leads to defective brain structures or tumour formation. Previous studies suggest changes of chromatin state are needed to direct neural stem cell differentiation, but the mechanisms are unclear.

Manipulation and Visualization of Peroxisomes in Drosophila.

Drosophila melanogaster is a proven metazoan model to investigate the fundamentals of human genetic diseases including peroxisome-related disorders. Drosophila have facile cell and animal culture but with a relatively simpler genome and organ morphology compared to vertebrates. Drosophila Schneider 2 (S2) cells have been used extensively as a platform for investigating peroxisome functions like transport along the cytoskeleton via their amenability to RNA-interference (RNAi)-based gene knockdown.
