From peers to partners: The peer‐context origins of adolescent heterosexual romance

Journal of Research on Adolescence, Volume 36, Issue 2, June 2026.
Abstract Romantic partnerships are highly influential for adolescent development, but many questions remain as to how and with whom such relationships emerge. By adopting a dynamic social network perspective, this study furthers our understanding of the peer‐related precursors to heterosexual adolescent romance.

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

Journal of Phycology, Volume 62, Issue 3, Page 818-845, June 2026.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

Phytoplankton growth and potential cyanotoxin production differ in response to nitrogen and phosphorus amendments in late summer communities from Kabetogama Lake (Minnesota, United States)

Journal of Phycology, Volume 62, Issue 3, Page 883-903, June 2026.
Abstract Cyanotoxins such as microcystin (MC), cylindrospermopsin, and saxitoxin are secondary metabolites that are rich in nitrogen (N). Most cyanobacteria grow best on reduced inorganic N (ammonium, NH4), but when NH4 is absent, cyanobacteria can activate physiological pathways to process other N forms (e.g., nitrate; NO3).

ACR3 as a Key Regulator Antimicrobial Lipopeptide Synthesis and Efflux in Bacillus velezensis HN‐1

Molecular Plant Pathology, Volume 27, Issue 6, June 2026.
Lipopeptides are natural antibiotics produced by Bacillus velezensis. Mutation of acr3 led to the complete loss of antimicrobial activity. Following the biological assays for validation, we found ACR3 protein may serve as a master switch of lipopeptides synthesis regulation, and control transmembrane transport of lipopeptides by the ABC pathway ...
