Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS 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 ...

The Position of Body Mass in a Network of Human Life History Indicators

open access: yesPsychological Topics, 2022
Body mass is widely recognized as a morphological trait which is important for fitness optimization both in humans and other animals. Here, we propose that body mass is a part of fast life history trajectory – the fitness optimization pattern which ...

Computed tomography shows high fracture prevalence among physically active forager-horticulturalists with high fertility

open access: yeseLife, 2019
Modern humans have more fragile skeletons than other hominins, which may result from physical inactivity. Here, we test whether reproductive effort also compromises bone strength, by measuring using computed tomography thoracic vertebral bone mineral ...

Material security, life history, and moralistic religions: A cross-cultural examination. [PDF]

open access: yesPLoS ONE, 2018
Researchers have recently proposed that "moralistic" religions-those with moral doctrines, moralistic supernatural punishment, and lower emphasis on ritual-emerged as an effect of greater wealth and material security.

On answering accusations in controversies [PDF]

open access: yes, 2009
Accusations are a very frequent type of speech act both in everyday life and in formal controversies, and answering accusations is a sophisticated type of linguistic practice well worth analysing from a pragmatic point of view.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS 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 ...

“The weight we carry in our backpack is not the weight of our books, it’s the weight of our community!”: Latinas negotiating identity and multiple roles [PDF]

open access: yes, 2020
In the United States, out of 100 Latina/o elementary students, only 0.3 will complete a doctorate degree. Latinas/os/x as a fast-growing minority population in the United States continue to be underrepresented in higher education. The underrepresentation

Endogenous ROS Levels in C. Elegans Under Exogenous Stress Support Revision of Oxidative Stress Theory of Life-History Tradeoffs [PDF]

open access: yes, 2014
Background: The oxidative stress theory of life-history tradeoffs states that oxidative stress caused by damaging free radicals directly underpins tradeoffs between reproduction and longevity by altering the allocation of energetic resources between ...

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS 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.

Uneven and combined development: modernity, modernism, revolution [PDF]

open access: yes, 2017
Trotsky’s theory of Uneven and Combined Development was born out of his experience of the Russian Revolution. To mark the centenary of the revolution, we are publishing a series of five pieces by Neil Davidson that explore the theory’s wider contribution
