Study shows common water pollutants cause heart damage in fish

Recent findings highlight the persistence of dihalogenated nitrophenols (2,6-DHNPs) in drinking water, resisting standard treatments like sedimentation, filtration, and boiling. The research demonstrates the severe cardiotoxic ...

Stem cell model offers first glimpse of early human development

It's one of life's most defining moments—that crucial step in embryonic development, when an indistinct ball of cells rearranges itself into the orderly three-layered structure that sets the stage for all to come. Known ...

An embryo (irregularly from Greek: ἔμβρυον, plural ἔμβρυα, lit. "that which grows," from en- "in" + bryein "to swell, be full"; the proper Latinate form would be embryum) is a multicellular diploid eukaryote in its earliest stage of development, from the time of first cell division until birth, hatching, or germination. In humans, it is called an embryo until about eight weeks after fertilization (i.e. ten weeks LMP), and from then it is instead called a fetus.
