Patterns of spontaneous and induced genomic alterations in .

This study explored the genomic alterations in , a key yeast in industrial biotechnology, under both spontaneous and mutagen-induced conditions. Our findings reveal that spontaneous mutations occur at a rate of approximately 4 × 10 events per base pair per cell division, primarily manifesting as single-nucleotide variations (SNVs) and small insertions and deletions (InDels). Notably, C-to-T/G-to-A transitions and C-to-A/G-to-T transversions dominate the spontaneous SNVs, while 1 bp deletions, likely resulting from template slippage, are the most frequent InDels.

π-HuB: the proteomic navigator of the human body.

The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

Sulfur-Rich Norbornadiene-Derived Infrared Transparent Polymers by Inverse Vulcanization.

Infrared (IR) transparent polymer materials prepared by inverse vulcanization, as a promising candidate to replace inorganic materials, are new materials for constructing key devices in IR optics. However, it is difficult to achieve a balance between infrared optical and thermal properties in polymers due to the intrinsic infrared absorption of organic materials. Herein, our strategy is to construct a high boiling point symmetrical molecular norbornadiene derivative cross-linking agent (DMMD) which can be inverse vulcanized with molten sulfur, and obtain Poly (S-r-DMMD) with different sulfur content by controlling the feed ratio of sulfur.
