Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

open access: yesThe FEBS Journal, EarlyView.
Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...

ON HISTORICAL (ANTI‐)REALISM

open access: yesHistory and Theory, EarlyView.
ABSTRACT The problem of historical realism has gained some new momentum recently, with a fresh challenge to what is taken to be an anti‐realist hegemony in the theory and philosophy of history. Unfortunately, this has also provided the opportunity for the reheating of old polemics and lazy scholarship that characterized the 1990s reaction to ...

Small but mighty: Impact hazards from iron Near‐Earth Objects

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Small asteroids can impact Earth unexpectedly, as demonstrated by the Chelyabinsk event in 2013. The warning times are likely to be short, and the first tools for fast hazard predictions have been developed in the last years for encounters with rocky or cometary objects, which quickly fragment in the atmosphere and cause airbursts. However, in

Accountability in Government Use of AI: Citizen Concerns and Preferences

open access: yesPublic Administration, EarlyView.
ABSTRACT Government adoption of AI opens the “pandora's box” of accountability, a core aspect of public value. Despite the centrality of governmental AI accountability, citizens' concerns and preferences in holding governments accountable for AI usage remain poorly understood.

Single Cell Multiomics of Hooked Potato Stolons Reveals Parallels to Shoot Apical Meristems in Arabidopsis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Solanum tuberosum L. (potato) is a key food crop, with its tubers serving as an important food source worldwide. Tuber development is a tightly regulated process involving the transition of a hooked stolon (a modified stem) to a tuber following the perception of mobile signals within the stolon tip. While genes like FLOWERING LOCUS T homologue
