Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Feedback on feedback – does it work? [PDF]
Critical CALL – Proceedings of the 2015 EUROCALL Conference, Padova, Italy, 2015 It is well documented that providing assessment feedback through the medium of screencasts is favourably received by students and encourages deeper engagement with the feedback given by the language teacher. In this short paper the authors will report the results of a case study where students moved from passively receiving feedback to actively ...

Breaking the Ecosystem Balance Over the Tibetan Plateau
Earth's Future, 2022 Ecosystem imbalance is often associated with a feedback mechanism, which a self‐amplifying or ‐dampening process expressed by a pathway of causal processes that come back to its starting point, establishing a cycle. Warming, which is increasing worldwide

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization
FEBS Letters, EarlyView.CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

Systems Research and Behavioral Science, 2017 The central question in the paper by Morecroft (2017) is whether ‘structure drives behaviour’ also holds over a long time period, or, in other words, whether feedback structures shaping trends endure over time. Morecroft revisits a model of the oil industry originally developed in the late 1980s and, changing only initial parameter settings, concludes ...

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.
