Co-occurrence networks and complexity of co-occurrence networks of (a) bacterial and (a) fungal in different locations of Flaveria bidentis and Eclipta prostrata.

New #studies show that a #bacterial molecule, #peptidoglycan, is present in the #brain and fluctuates with #sleep patterns. This challenges the idea that sleep is solely brain-driven, instead suggesting it’s a #collaborative process between our #bodies and #microbiomes. The theory links #microbes not only to sleep but also to #cognition, #appetite, and #behavior, pointing to a profound #evolutionary relationship

Title and author list of the online preprint by Bijl and Sliwinska et al. (submitted to Biogeosciences) EGUsphere (https://doi.org/10.5194/egusphere-2025-1467) entitled "Reviews and syntheses: Best practices for the application of marine GDGTs as proxy for paleotemperatures: sampling, processing, analyses, interpretation, and archiving protocols", with a note which reads "Revised manuscript accepted for BG"—"BG" stands for "Biogeosciences"—and the co-editor-in-chief’s comment which reads "This publication provides a comprehensive review of the use of GDGTs (Glycerol Dialkyl Glycerol Tetraethers) for reconstructing past temperatures, with a particular focus on marine applications. It covers the full research workflow — from sample collection and processing to analytical methodologies, data interpretation, and data archiving. Importantly, the authors highlight best practices and propose recommendations to standardize approaches across the field. This review therefore serves as a valuable reference for both the paleoclimatology and organic geochemistry communities.".

Top right: Structural overlay of zoocin A from Streptococcus zooepidemicus (UniProt ID: O54308) and Woldo, a candidate PGH from Halogranum salarium B-1 (UniProt ID: J2ZZK6), highlighting homologous M23 domains but divergent cell wall binding domains. TRD: target recognition domain. PG: peptidoglycan. Bottom right: Images of bacterial cells following exposure to H. volcanii supernatants expressing Woldo, Danwoldo or the control (as above). Bacteria are stained using LIVE/DEAD BacLight bacterial viability staining kit with ingress of red dye into bacterial cells indicative of cells with terminally compromised cell wall integrity.$

Top: Schematics explaining how the categorical variables effective-drug-use, ineffective-drug-use and resistance-without-drug are defined based on the set of drugs consumed by the host and resistances carried on strains. Since these three variables are defined analogous to levels of a categorical variable, their effect sizes are to be interpreted relative to the fitness effect corresponding to ‘baseline for comparison’. Bottom: An example showing how the values of the three covariates vary with time. The first two episodes of carriage are resistant to penicillin. The orange lines indicate the value of the covariates for the first 10A serotype as used in clearance models. The green lines indicate the value for the second 10A serotype as used in establishment models.
