This Hubble image shows NGC 2835, an intermediate spiral galaxy approximately 28.5 million light-years away in the constellation of Hydra. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). It is based on data obtained through five filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

A Somali sengi (Galegeeska revoilii) at the Assamo locality in Djibouti. As is observed in other sengi species, Somali sengis have some variation in pelage colors. These differences seem to correspond to the color variation of substrates between occurrence localities. At the Assamo site, in the extreme southeastern corner of Djibouti, sengi habitats are comprised of rocks with more rusty coloration than elsewhere in the country. Compared to other Djiboutian sites, sengis from Assamo have dorsal pelage hairs with more pronounced reds. Image credit: Steven Heritage.

Overview of bacterial biotransformation of the odorless physiological malodor precursor Cys-Gly-3M3SH, which is secreted onto the surface of skin by underarm apocrine glands, subcutaneously located in the hypodermis. In Staphylococcus hominis, Cys-Gly-3M3SH is actively transported by the di-/tri-peptide transporter (DtpT) along with the movement of protons (1). Once inside the cell the terminal glycine is cleaved by a dipeptidase (PepA) to release Cys-3M3SH (2), which is metabolized by a C-S β-lyase liberating volatile 3M3SH (3), which diffuses or is exported out of the cell (4). The catabolism of Cys-Gly-3M3SH provides carbon and nitrogen as nutritional incentive in the form of glycine, ammonia and pyruvate. Image credit: Rudden et al, doi: 10.1038/s41598-020-68860-z.
