“We couldn’t use transcriptomics to identify which subset it was, because the ontogeny markers were diluted,” says Merad. To solve this problem, she added CITE-seq to the scRNA-seq analysi ...

The study uncovers gene expression signatures that predict neonatal sepsis, highlighting the potential for early intervention ...

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 ...

Here we demonstrate an unexpected degree of flexibility and cognition in a decision made by a hunting animal at reflex-like speed. Based on observing initial speed, direction, and height of falling ...

Social Cognition in a Usage-Based Model of Language Change – from Immediate (I-I) to Extended Intersubjectification (E-I) 4. The Intersubjective Gradience Model Applied – from Immediate (I-I) to ...

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" ...

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 ...
