Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Review of "Political Blackness in Multiracial Britain" by Mohan Ambikaipaker (University of Pennsylvania Press)

open access: yesLateral, 2019
Mohan Ambikaipaker’s "Political Blackness in Multiracial Britain" is distinctive both for its setting and for its personal engagement. Ambikaipaker practiced "activist anthropology" by carrying out "observant participation" as a caseworker for the Newham

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Introduction. Slavery and the Racialization of Humanity: Coordinates for a Comparative Analysis

open access: yesAntropologia, 2020
This introduction provides some historical and conceptual coordinates for a comparative analysis of the multifarious ethnographic manifestations and performative powers of the “racial legacies” of slavery in contemporary contexts in West Africa, North ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Making Blackness, Making Policy [PDF]

open access: yes, 2012
Too often the acknowledgment that race is a social construction ignores exactly how this construction occurs. By illuminating the way in which the category of blackness and black individuals are made, we can better see how race matters in America ...

Blackness Enhancement

open access: yes, 1991
Since apparent brightness increases as an intermittent luminous source decreases from flicker fusion to approximately 10 cps, the phenomenal blackness induced by an intermittent annulus should also increase as a result of brightness contrast.

Ante-Anti-Blackness: Afterthoughts

open access: yesLateral, 2012
Sexton sees to ask again about the tension between what has been coined afro- pessimism and black-optimism or what black intellectuals long have discussed as life after or in the social death of slavery.

La « jeunesse » comme répertoire critique

open access: yesAteliers d'Anthropologie, 2020
This article analyses the construction and usage of the “youth” category by groups that subscribe to Rastafarianism and hip-hop culture in Burkina Faso.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
