Eye movements time-locked to retrieval and novelty during learning preferentially occur at distinct phases of hippocampal theta.

Systems level modeling of cyanobacterial mechanism for concentrating carbon dioxide shows optimal organization and enzymatic activity for enhanced carbon fixation.

A new pathway is described involving the estrogen receptor alpha in the acute response of small arteries to flow independent of the ligand (estrogen) and of the nuclear signaling.

Excitatory and inhibitory cortical neurons drive parallel vasodilatory pathways, while vasoconstriction is mediated exclusively by inhibition acting via Neuropeptide Y binding to Y1 receptors.

Slow, continuous changes in eye position when gaze is fixed, previously believed to be random drifts, are shown to exhibit highly systematic and short-latency response characteristics to visual stimuli.

X-ray crystal structures capture ATP-dependent chalcogenide exchange from selenocyanate at the nitrogenase Fe protein cluster in the absence of the MoFe protein, an unexpected result as the Fe protein cluster is not traditionally perceived as a site of substrate binding.

Ablation of the sarcomeric protein myopalladin (MYPN), associated with human cardiomyopathies, results in dilated cardiomyopathy, which is severely aggravated by biomechanical stress, suggesting that skeletal myopathy patients carrying MYPN loss-of-function mutations may develop cardiomyopathy under conditions of cardiac stress.

Although puromycin staining is often used to examine subcellular translation, puromycin-labeled proteins are rapidly released from ribosomes even in the presence of elongation inhibitors, which may confound translation site localization.

A shift in fitness optimum of a polygenic trait rapidly introduces small frequency differences between alleles with effects aligned with and opposing the shift, which gradually translate into small differences in fixation probability.

The genome of Thermovibrio ammonificans encodes ancestral pathways (e.g., hydrogen oxidation) and more recently acquired ones (e.g., nitrate reduction) and a hybrid pathway for CO₂ fixation.
