Long‐term interventions by conservation and development projects support successful recovery of tropical peatlands in Amazonia

People and Nature, Volume 7, Issue 4, Page 871-886, April 2025.
Abstract Rural communities in Amazonia rely on harvesting Mauritia flexuosa fruit, a dominant peatland palm, for their subsistence and income. However, these palms are felled to harvest the fruits, which has led to reduced resource availability due to the pressure exerted by the increasing fruit demand.

Billion‐Scale Expansion of Functional hiPSC‐Derived Cardiomyocytes in Bioreactors Through Oxygen Control and Continuous Wnt Activation

Advanced Science, Volume 12, Issue 11, March 20, 2025.
This work shows the development of a bioreactor‐based bioprocess for the expansion of human‐induced pluripotent stem cell‐derived cardiomyocytes (hiPSC‐CM), obtained after cardiac differentiation of hiPSC. By combining the activation of the Wnt pathway, through continuous perfusion of CHIR99021, with a controlled mild hypoxia environment, we maximize ...

Computational Study on the Photo‐Induced Antibiotic Activity of an Azoquinolone with Promising Applications in Photopharmacology

ChemPhotoChem, Volume 9, Issue 3, March 2025.
Photopharmacology is an evolving field aimed at transforming drug efficacy through light control. This research explores an azo‐quinolone, using a crucial molecular photoswitch, and its light‐induced antibiotic activity. Through ab‐initio calculations, we elucidate the mechanisms of its thermal and photochemical reactions, providing a comprehensive ...

Lasing in Crystals Based on 7‐Azaindole‐Phenylhydrazone Organoboron Compounds

Advanced Functional Materials, Volume 35, Issue 5, January 29, 2025.
Novel 7‐azaindole phenylhydrazone derivatives and their boron complexes are processed into crystalline microfibers exhibiting enhanced emission and low‐threshold laser action. Micrometer‐scale needles demonstrate optical waveguiding and random lasing performance by partially suppressing structural relaxation and non‐radiative decay.

Addressing Perceived Insecurity in Public Transportation: A PLS‐SEM Approach

Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.
The sense of insecurity and fear of crime associated with public transportation are disadvantages that can deter individuals from using public transportation. We propose a methodology based on partial least squares structural equation modeling (PLS‐SEM) to examine perceptions of insecurity among public transportation users in the Gran Valparaíso area ...

The experimental implications of the rate of temperature change and timing of nutrient availability on growth and stoichiometry of a natural marine phytoplankton community

Limnology and Oceanography, Volume 69, Issue 8, Page 1769-1781, August 2024.
Abstract Climate change increases the need to understand the effect of predicted future temperature and nutrient scenarios on marine phytoplankton. However, experimental studies addressing the effects of both drivers use a variety of design approaches regarding their temperature change rate and nutrient supply regimes.
