Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Mapping the 'gray area' – commentary to Tulumello
As a response to Simone Tulumello’s essay ‘Generalization, epistemology and concrete: what can social sciences learn from the common sense of engineers’, in this commentary I reflect on some of the issues that I consider key elements in his provocative original text.

Mechanisms of parasite‐mediated disruption of brain vessels
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Gray images of the linear codes and their dual codes over F4+uF 4
The linear codes over ring F4+uF4 and field F4 were studied.By using the Gray weight wG ,the Gray distance dG of codes C over F4+uF4,and the Gray map ψ from (F4+uF4)n to F 4 2n ,the Gray image ψ(C)of linear codes C over F4+uF4 were ...

La Porte City Chert - Devonian Subsurface Formation in Central Iowa: Report of Investigations 4, 1967 [PDF]
A study of well samples from central Iowa shows that a distinct rock-stratigraphic unit is present beneath the Devonian Wapsipinicon Formation and above the characteristic dolomites and cherts of the Silurian Niagaran Series.

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

This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
