A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

A General Workflow for Tangential Flow Filtration Perfusion Scale‐Up

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Tangential flow filtration (TFF) perfusion using hollow‐fiber modules offers substantial advantages over other mammalian cell retention technologies. Recently, increased awareness of Starling flow has helped to enhance filtration performance to similar, or even higher levels compared to alternative technologies.

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

BMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

Flight of the dragons: a global review of migration in Odonata

Biological Reviews, EarlyView.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

What drives animal responses to high severity fire? The role of functional traits

Biological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.
