Achieve Sustainability by Easing Population to 4 Billion by 2200

open access: yesSustainable Development, EarlyView.
ABSTRACT The past century of massive increases in human population and resource use has seen many undesirable environmental effects, ranging from biodiversity loss to climate change. But a research gap exists, as the ultimate causes are often not described with precision or mentioned at all.

Seeded Growth of Plasmonic Core‐Shell NU‐1000 NanoMOFs With Intracellular Optical Readout

open access: yesSmall, EarlyView.
Seed‐mediated growth yields plasmonic core‐shell nanocomposites by encapsulating gold nanoparticles within NU‐1000 nanoMOFs, preserving morphology and optical response. The materials exhibit tunable photoluminescence quenching, efficient photothermal heating, and SERS activity.

A Triangulenum‐Based Biosensor Platform for Mapping Kinase Activity in T Cells

open access: yesSmall, EarlyView.
Novel peptide biosensors based on long‐lifetime triangulenium dyes are developed for the real‐time, non‐invasive mapping of Akt1 and Src kinase activities in living cells. Utilizing FLIM microscopy, these highly specific, biocompatible probes overcome cellular autofluorescence.

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

Antimicrobial Residues in a Key Cerrado River: Distribution, Persistence, and Effects on Zebrafish Embryo‐Larval Development

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The current study aimed to quantify the antimicrobials amoxicillin (AMX), cefazolin (CFZ), chloramphenicol (CHL), metronidazole (MTZ), and sulfamethoxazole (SX) in effluents and surface water of an important Cerrado river, calculate their half‐lives, and analyze their ecotoxicity following single and combined exposures.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

open access: yesJournal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

open access: yesJournal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...
