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 ...

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）产生热量，成为治疗和预防肥胖及相关代谢疾病的潜在靶点。研究 ...

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

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 ...

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 ...

In each successive annual non-breeding plumage, satellites only grow more and more prominent white neck rings. The ontogeny of this plumage character is similar to that of "status signalling badges" ...

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

How do plants maintain ecosystems and thus life? In the Master’s Programme in Integrative Plant Sciences, you study the diversity of wild and cultivated plants from the Arctic to the Tropics, as well ...

However, the cellular mechanisms by which MC4R regulates reproduction are unknown. Kiss1 neurons directly stimulate gonadotropin-releasing hormone (GnRH) release through two distinct populations; the ...
