From a neuroethological perspective, the spectacular diversity in behavioral ecology among chiropterans is suggestive of a similar richness in brain organization. Dramatic evidence that this is the ...

(A) The de novo inactivation model requires many rounds of inactivation and reactivation: the paternal germline initiates meiotic sex-chromosome inactivation, but the X chromosome is completely ...

Specifically, Haeckel proposed that "ontogeny recapitulates phylogeny." This pithy bit of jargon, when translated into English, asserts that as an embryo develops, it passes through stages that ...

One of Darwin's contemporaries, German biologist Ernst Haeckel, summed up the argument in a famous, pithy statement: "Ontogeny recapitulates phylogeny.'' That is to say, in the process of ...

Sea otters are famed for their luscious pelts, but the fur almost led to their extinction. By 1938, only a tiny population of ...

The gray squirrel’s appearance differs seasonally. The yellowish brown summer coat becomes thicker and gray in winter, the pelage of some individuals strikingly silver-gray. Underparts and eye-rings ...

Acanthocyte Erythrocyte identified by numerous spiny cytoplasmic projections; similar to a Burr cell Acanthocytosis, condition in which the majority of erythrocytes are acanthocytes. Anemia ...

can also depend on ontogeny, or the stage of life the snake is in. For example, a newborn Russell’s viper’s venom is more ...

Fortunately, most lesions are detected early and surgically removed, accounting for disease’s high survival rates. Importantly, ontogeny of epidermal SCC parallels cancers associated with high ...

Early childhood vitamin D insufficiency affects neuronal development, axonal connections, dopamine ontogeny, and brain structure and function. The review findings highlighted fatigue modulation by ...

该研究揭示了m6A通过调控前列腺素在棕色脂肪中的合成，进而影响全身代谢的新机制，拓展了m6A及其他表观遗传修饰在代谢调控中的研究思路。 棕色脂肪组织（BAT）因其通过解偶联蛋白1（UCP1 ...
