Emissions of methane from northern peatlands: a review of management impacts and implications for future management options

Ecology and Evolution, 2016
Northern peatlands constitute a significant source of atmospheric methane (CH4). However, management of undisturbed peatlands, as well as the restoration of disturbed peatlands, will alter the exchange of CH4 with the atmosphere.

The effects of changing climate on faunal depth distributions determine winners and losers

, 2014
Changing climate is predicted to impact all depths of the global oceans, yet projections of range shifts in marine faunal distributions in response to changing climate seldom evaluate potential shifts in depth distribution.

A Superhydrophobic 3D Cell Culture System Reveals the Mechanobiological Role of Cancer‐Associated Fibroblasts in Prostate Cancer Metastasis

Advanced Healthcare Materials, EarlyView.
A superhydrophobic 3D cell culture platform enables rapid and consistent formation of heterotypic tumor–stroma clusters, and reveals how physiological shear conditions influence metastatic signaling. Mechanical stimulation of cancer‐associated fibroblasts promotes sustained cytokine secretion and survival‐promoting pathways, showing how multicellular ...

Multidirectional Motion Strategy of Miniature Water Surface Robot Actuated by Single Exciter

Advanced Robotics Research, EarlyView.
A novel multidirectional motion strategy on the water surface based on a single exciter is proposed, and a single‐exciter single‐plate module is developed for actuation. The driving forces generation mechanism of the module is revealed from the perspective of the asymmetric surface wave field.

On the Discorhabdins Leading to the Aleutianamine Ring System: A One‐Step in Situ Transformation Characterized Through Computational and Experimental Studies and Its Implications on Biosynthesis, Synthesis, and Pharmacology

Angewandte Chemie, EarlyView.
The thiocarbenium ion rearrangement of 3‐dihydrodisorhabdin B greatly increases the recovery of aleutianamine from Latrunculia spp., a pyrroloiminoquinone natural product with potent activity against drug‐resistant cancers, collected from the deep‐ocean along the Aleutian Islands.

Li-Yorke chaos in hybrid systems on a time scale [PDF]

, 2015
By using the reduction technique to impulsive differential equations [1], we rigorously prove the presence of chaos in dynamic equations on time scales (DETS). The results of the present study are based on the Li-Yorke definition of chaos.

CypD Dependent mPTP Opening Is Crucial for Oxidized Mitochondrial DNA Release in Ferroptosis

Advanced Science, EarlyView.
Ferroptosis is driven by mitochondrial permeability transition pore (mPTP) opening, which induces mitochondrial swelling and releases oxidized mitochondrial DNA. The released mtDNA activates cGAS–STING signaling, promotes ferritinophagy, and amplifies ferroptotic cell death. Disruption of mtDNA repair sensitizes tumors to ferroptosis in vivo, revealing
