Article Synopsis
- * The study details the morphology of the Canarian copper fly (Calliphora splendens) and compares it to other Calliphora species found in Africa, the Iberian Peninsula, and Macaronesia.
- * Genetic analysis shows a close connection between C. splendens and several other Calliphora species, while its ability to produce unisexual offspring and its association with the endemic laurel forest habitat highlight its relict nature.
Article Synopsis
- Metformin, a commonly prescribed diabetes medication, is often detected in wastewater and surface waters due to its stability and poor breakdown, potentially harming aquatic ecosystems.
- An 8-week experiment in a freshwater lake tested the impact of metformin at concentrations of 0, 5, and 50 μg/L on various aquatic organisms, including microbes and zooplankton.
- Results showed that metformin remained stable in water, with no significant adverse effects on aquatic communities or organisms, suggesting limited environmental impact despite its high concentration in wastewater.
To assess aquatic toxicity of natural wetlands in the Athabasca oil sands region (AOSR) of northern Alberta, fifteen collected water samples were tested for their ability to affect survival and development of fathead minnow embryos. Wetland waters were also assessed for toxicants from natural oil sands bitumen deposits (Na, Cl, metals, naphthenic acids (NAs), naphthenic acid fraction compounds (NAFCs), polycyclic aromatic hydrocarbons (PAHs), and alkylated PAHs). Water samples from four wetlands caused toxicity to fish embryos.

It was not until the end of the 20th century that the Institute of Medicine (IOM), now the National Academy of Medicine, and the Centers for Disease Control and Prevention, Division of Laboratory Systems (CDC DLS), focused on laboratory tests and how testing processes can be designed to benefit patient care. In collaboration with CDC DLS, the American Society for Microbiology (ASM) used an evidence review method developed by the CDC DLS to develop a program for creating laboratory testing guidelines and practices.
