Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Mapping the Food Landscape in New Hampshire [PDF]
, 2019 In this brief, Jess Carson explores the food landscape of New Hampshire, documenting where lower incomes and low population density might lead to food insecurity, and mapping the locations of various food sources.

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Migration, Urbanization and Food Security in Cities of the Global South: 26–27 November 2012, Cape Town, South Africa [PDF]
, 2013 The disjuncture between food security, migration and urbanization must be overcome. It is an institutional as well as a thematic disconnect on a global scale. Food security is primarily about access to food, not agricultural production.

Strong ties, weak actors? Social networks and food security among farm workers in South Africa [PDF]
, 2019 Farm workers employed on commercial farms are among the poorest and most food insecure population groups in South Africa. This study investigated formal (organisational) and informal exchange relations and the association with food security within ego (N=

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 ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in
