Microbiome & Metabolic Health: Researchers isolated a previously uncharacterized Enterococcus strain from the gut of the dyeing poison dart frog (native to Brazil, French Guiana, and Suriname). In high-fat diet mice, the bacteria appeared to reduce weight gain and improve insulin sensitivity by producing compounds that interact with mammalian metabolic pathways. Environment & Risk to Coastal Life: Petrobras has begun drilling in Brazil’s Equatorial Margin near the Amazon River mouth after long disputes. Scientists and environmentalists warn the Amazon Reef system is rich but under-studied, and that an oil spill could spread to mangroves and fisheries, potentially affecting neighboring areas. Public Health Access to Clean Water: A new global map highlights where safe drinking water is still out of reach: more than 2 billion people lack safely managed services, with access far higher in Europe, North America, and Australia than in several low-income countries. Wildlife & Conservation News: A rare saki monkey birth at Drusillas Park marks the fourth generation of the same family line at the Sussex zoo, continuing a long-running European breeding program.
