Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Anticipation of cognitive conflict is reflected in microsaccades: Evidence from a cued-flanker task
Journal of Eye Movement Research, 2019 Microsaccade frequency has recently been shown to be sensitive to high-level cognitive processes such as attention and memory. In the present study we explored the effects of anticipated cognitive conflict. Participants were administered a variant of the

Selective disruption of stimulus-reward learning in glutamate receptor gria 1 knockout mice. [PDF]
, 2003 Glutamatergic neurotransmission via AMPA receptors has been an important focus of studies investigating neuronal plasticity. AMPA receptor glutamate receptor 1 (GluR1) subunits play a critical role in long-term potentiation (LTP).

User Behavior As A Music Rating Cue
, 2006 The "My Rating" feature on iTunes has always felt a little clumsy. First of all, I hardly ever listen to music on iTunes itself- I listen to most of my music on my iPod. Secondly, I don't want to have to *do* anything convoluted or extra in order to register that I like or dislike a song.

Speaking Rate and Fundamental Frequency as Speech Cues to Perceived Age
Journal of Voice, 2008 This study aimed to specify a set of acoustic cues fundamental to vocal aging and to establish their perceptual relevance, using acoustic analysis and perceptual testing. Three experiments were conducted to identify the perceptual correlates of the aging voice.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
