<title>Abstract</title> Rivers transport 300 to 5,000 Mg of mercury (Hg) annually coastal oceans through estuaries, contributing 20–45% total Hg input, with 100 1,500 reaching the open ocean. However, impact estuarine circulation and stratification on methylation remains uncertain despite their known influence other metal exports. This study developed three models assess transformation under different salinity-driven regimes—well-mixed, slightly stratified, highly stratified—using data from...
Abstract For billions of years, life has continuously adapted to dynamic physical conditions near the Earth’s surface. Fossils and other preserved biosignatures in paleontological record are most direct evidence for reconstructing broad historical contours this adaptive interplay. However, dating earliest history exceedingly rare. Here, we combine phylogenetic inference primordial rhodopsin proteins with modeled spectral features Precambrian Earth environment reconstruct paleobiological...
Abstract The Galactic Habitable Zone (GHZ) is a region believed hospitable for life. To further constrain the GHZ, observations have been conducted of J = 2 → 1 transitions methanol (CH 3 OH) at 97 GHz, toward 20 molecular clouds located in outer Galaxy ( R GC 12.9–23.5 kpc), using 12 m telescope Arizona Radio Observatory. Methanol was detected 19 out observed clouds, including sources as far 23.5 kpc. Identification secured by measurement multiple asymmetry and torsional components...
