Economists on Darwin's theory of social evolution and human behaviour [PDF]

open access: yes, 2005
The purpose of this article is to analyse the way economists interested in social and economic evolution cite, mention or refer to Darwin. We focus on the attitude of economists towards Darwin's theory of social evolution - an issue he considered as ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The Twitter origins and evolution of the COVID-19 “plandemic” conspiracy theory

open access: yesHarvard Kennedy School Misinformation Review, 2020
Tweets about “plandemic” (e.g., #plandemic)—the notion that the COVID-19 pandemic was planned or fraudulent—helped to spread several distinct conspiracy theories related to COVID-19.

Haplodiploidy and the evolution of eusociality : worker reproduction

open access: yes, 2013
The authors acknowledge the European Research Council, the Royal Society, and Balliol College for funding.Hamilton’s haplodiploidy hypothesis suggests that the relatively higher relatedness of full sisters in haplodiploid populations promotes altruistic ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Feature theory and the two-step hypothesis of Müllerian mimicry evolution

open access: yes, 2010
The two-step hypothesis of Müllerian mimicry evolution states that mimicry starts with a major mutational leap between adaptive peaks, followed by gradual fine-tuning.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Understanding Capitalism from the Evolution of Capital Theory

open access: yes, 2018
Understanding Capitalism from the Evolution of Capital Theory is a prospective that integrates economic history and the history of economic thought, from the early French contributors (physiocrats) to the modern capital theory ...
