From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

The effects on local livelihoods of a Wetland development scheme in a Zimbabwean village : an ethnographic study [PDF]

open access: yes, 2011
This study explores the effect on local livelihoods of the New Gato Wetland Development Project (NGWP) in a rural village in Zimbabwe, in light of a post development critique which has labelled most development as a ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

open access: yesFEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Key conditions for success of partnerships for conservation of threatened species and threatened ecological communities

open access: yesConservation Science and Practice
Multi‐stakeholder partnerships that leverage the skills and resources of partner organizations are becoming an increasingly popular strategy to undertake recovery actions for threatened species and threatened ecological communities. When partnerships are

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Revisiting the Definition and Recognition of Indigenous Peoples and Local Communities for Biodiversity Conservation

open access: yesEcology and Evolution
Globally, there is no single universally agreed‐upon definition of Indigenous Peoples, yet specific criteria are typically used to define whether someone is Indigenous or not, namely self‐identification, historical continuity, linkage to ancestral land ...

Torture, Livelihoods and Rehabilitation

open access: yesTorture Journal
The understanding of torture has evolved to encompass a complex interplay of factors including poverty, politics, health and psychosocial factors which increase vulnerability to torture. While torture remains a grave human rights violation, it is acknowledged as widespread and intertwined with broader human rights abuses.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.
