Postural adjustments that reduce ankle leverage in kangaroos enhance tendon stress and elastic energy storage at higher speeds, providing energetic efficiency during hopping but potentially constraining the maximum size achievable by large species.
Combined with high-throughput yeast genetics, a split green fluorescent protein encoded directly in the mitochondrial DNA helps to identify targeting signals and functions of dually localized proteins.

A genomic analysis shows that the evolution of genome size and gene content among fungal pathogens in the class Sordariomycetes varies depending on their interactions with hosts and vectors.
Pyruvate dictates redox balance and cell size, establishing metabolism as a dominant regulator of cellular fitness, unveiling new strategies to modulate cancer, regeneration, and diabetes.
The retrieval-extinction paradigm elicits a short-term fear amnesia that differs in cue specificity, timescale, and dependence on thought-control ability from the long-term amnesia believed to be associated with memory reconsolidation.
Analyzing population-level chromatin accessibility data shows added benefit over utilizing only gene expression data in elucidating the genetic mechanism of disease-associated variants.
