Electrified rhythms: How hydropower infrastructure transforms hydrosocial relations of riverine communities in the Lower Sogamoso River, Colombia

People and Nature, EarlyView.
Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

Human neural rosettes secrete bioactive extracellular vesicles enriched in neuronal and glial cellular components

Scientific Reports
Extracellular vesicles (EVs) play a critical role in the development of neural cells in the central nervous system (CNS). Human neural rosettes (hNRs) are radial cell structures that assemble from induced pluripotent stem cells (hiPSCs) and recapitulate ...

Monitoring volcanic ash in the atmosphere [PDF]

, 2013
On several occasions, volcanic eruptions in the Andes have disrupted airspace for prolonged periods. Such eruptions include those in the southern Andes at the Chaitén volcano on 6 May 2008, and at Puyehue-Cordón Caulle on 4 June 2011.

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

Pest Management Science, EarlyView.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Versatile machine learning algorithms for FTIR spectroscopy: differentiating crosslinked and non-crosslinked gelatin samples

Discover Sustainability
From the food and pharmaceutical industries there is a growing demand for biomaterials from industrial waste, which are biodegradable, non-toxic, non-carcinogenic and biocompatible, as is the case of the gelatin.

Acute toxicity of arsenic and oxidative stress responses in the embryonic development of the common South American toad Rhinella arenarum [PDF]

, 2015
Arsenic (As), a natural element of ecological relevance, is found in natural water sources throughout Argentina in concentrations between 0.01mg/L and 15mg/L. The autochthonous toad Rhinella arenarum was selected to study the acute toxicity of As and the

Synthesis of Large‐Area 2D Prussian Blue as Ion‐Transport Channels for Non‐Volatile Memristors

Small, EarlyView.
A robust liquid‐liquid interfacial synthesis enables continuous, large‐area 2D Prussian blue films with tunable thickness from ∼2 nm to hundreds of nanometers. Controlled reduction guides slow, directional layer growth, yielding high‐quality flakes. These films show exceptional ion transport and device integration, demonstrated in memristors with long ...

Developmental toxicity of bisphenol A diglycidyl ether (epoxide resin badge) during the early life cycle of a native amphibian species [PDF]

, 2016
Bisphenol A diglycidyl ether (BADGE) is used in packaging materials, in epoxy adhesives, and as an additive for plastics, but it is also a potential industrial wastewater contaminant.

Temporal dynamics in functional fruit traits of native and invasive fleshy fruited plants in subtropical Andean forests

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruits encompass the energetic and material flow between both interacting parties in frugivore‐mediated seed dispersal. Since fruit traits matter in frugivores' foraging decisions, the temporal dynamics of fruit traits might influence interaction outcomes.
