The budding yeast kinesin Kip2 is a polymerase that uses its processive motility in a positive feedback loop to promote microtubule growth.

Somatosensory feedback is transmitted to many sensory and motor cortical regions within 25 milliseconds and ongoing behavioural tasks alter the spatiotemporal pattern of this perturbation-related activity, supporting rapid motor responses to attain behavioural goals.

Positive feedback between contractile ring myosin and compression-driven cortical flow can explain the exponential accumulation of contractile ring components and constriction rate acceleration that ensures timely cell separation during cytokinesis.

Lefty-mediated feedback inhibition of Nodal signaling mitigates signaling perturbations, but is dispensable for development.

Neural confidence signals can take the role of reward signals and explain perceptual learning without external feedback as a form of internal reinforcement learning.

Neurophysiological and behavioral approaches reveal how coordinated input from descending pathways shapes the tuning properties of electrosensory neurons in order to optimize coding of natural stimuli through temporal whitening.

Reducing visibility with higher image presentation rates increases recurrent processing demands along the visual processing pathway to resolve object recognition.

Nonlinear H₂O₂ scavenging by peroxiredoxins drives acquired stress resistance and replicative lifespan hormesis.

Experiment-driven quantitative model of IL-2 secretion demonstrates how T cells integrate their digital antigen responses into an analog-scaled output.

FGF morphogen gradient self-generates a recipient tissue-specific contour by feedback-regulating its cytoneme-mediated dispersion.
