Laccases from lactic acid bacteria show cuprous oxidase activity and capture Cu(II) and Ag(I) ions

open access: yesProtein Science, Volume 35, Issue 1, January 2026.
Abstract Several laccases derived from lactic acid bacteria (LAB) display specific structural features, such as two methionine residues at the entrance of the T1Cu center, and an extended C‐terminal end enriched in methionine and histidine. To investigate their functional roles, we engineered mutant variants of the laccase Pp4816 from Pediococcus ...

The Least-Area Tetrahedral Tile of Space

open access: yes, 2019
We determine the least-area unit-volume tetrahedral tile of Euclidean space, without the constraint of Gallagher et al. that the tiling uses only orientation-preserving images of the tile.

Affine‐Image‐Driven and Finite‐Time Stable Formation Control for Multi‐AUV Systems With Unknown Complex Disturbances: A Geometric Perspective

open access: yesIET Signal Processing, Volume 2026, Issue 1, 2026.
Formation control of multi‐autonomous underwater vehicle (AUV) systems is essential for collaborative ocean tasks such as environmental monitoring and resource exploration, but it is hindered by challenges like limited flexibility in formation transformation, model uncertainties, and unknown ocean current disturbances.

PGN_0298 in the Assembly and Insertion Machinery (Aim) Operon Is Essential for the Viability of Porphyromonas gingivalis

open access: yesMicrobiology and Immunology, Volume 70, Issue 1, Page 9-14, January 2026.
ABSTRACT Porphyromonas gingivalis is a typical periodontal pathogen, and one of its key virulence factors is the powerful protease gingipains. Gingipains are secreted via the type IX secretion system (T9SS) and are associated with the assembly and insertion machinery (Aim) operon (PGN_0296 to PGN_0301), which encodes both T9SS components and non‐T9SS ...

Health coverage and farmworker productivity

open access: yesAmerican Journal of Agricultural Economics, Volume 108, Issue 1, Page 309-335, January 2026.
Abstract Farmworkers are often subject to hazardous working conditions, experience a disparity in health insurance coverage, and are vulnerable to chronic health conditions and injury. Although recent health care mandates have improved access to healthcare, many agricultural employers still do not offer coverage for their employees. Because farmworkers
