Developing and Evaluating Aquatic Passive Sampling of Environmental DNA for Microbial Community Profiling

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Environmental DNA (eDNA) metabarcoding has transformed biodiversity monitoring across taxa from bacteria to mammals, yet sample collection remains a major bottleneck. Passive sampling via adsorption and entrapment has emerged as a promising alternative to overcome the limitations of conventional active filtration.

A PLETHORA3/7 transcription factor shapes cucumber shoot architecture

open access: yesNew Phytologist, Volume 250, Issue 1, Page 230-245, April 2026.
Summary PLETHORA transcription factors (PLTs) are master regulators of plant development. Loss of shoot meristematic PLTs leads to reduced phyllotactic regularity and robustness in Arabidopsis and increased inflorescence branching in tomato. Whether these factors have similar functions in other species is not known.

Hypogravity simulation using the Variable Gravity Suspension System: A technical report

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 1580-1596, 1 April 2026.
Abstract Human movement has evolved within Earth's gravitational environment (1 g; −9.81 m s−2). Future human exploration of terrestrial bodies, including the Moon (0.17 g; −1.62 m s−2) and Mars (0.38 g; −3.71 m s−2), will require astronauts to live and work within reduced gravitational environments (hypogravity).

Catalytic Amyloids: Turning Fibrils Into Biocatalysts

open access: yesChemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Studies of friction and wear characteristics of various wires for wire-brush skids [PDF]

open access: yes
The friction and wear characteristics of 22 types and sizes of wires for potential use in wire-brush skids were studied. These characteristics were determined by placing brushes made from candidate wires on a belt sander whose moving belt simulated ...
