Reversible Metamorphosis of a Conjugated Polymer Induced by Photoexcitation

open access: yesAdvanced Photonics Research, Volume 7, Issue 3, March 2026.
Photon absorption in conjugated polymers induces a persistent, reversible transformation in their optoelectronic and structural properties. At elevated temperatures, photoexcitation alters the molecular conformations and (re)organization of polymer molecules within low‐viscosity matrices, resulting in a persistent “photomemory” effect with blue‐shifted

Landscape heterogeneity affects developmental and dispersal‐related traits of a butterfly in agricultural landscapes

open access: yesEcological Applications, Volume 36, Issue 2, March 2026.
Abstract The loss and fragmentation of natural habitats due to the intensification of agricultural land use have detrimental impacts on the biodiversity of arthropods. The reduction of natural habitats results in a decreased availability of essential resources, which may select for rapid development and phenotypes enhancing dispersal ability.

Factors Contributing to Short‐Term Structural Variability in a Longitudinal MRI Dataset

open access: yesHuman Brain Mapping, Volume 47, Issue 4, March 2026.
We applied a multilevel sparse PLS model to identify factors associated with short‐term, intraindividual changes in the regional gray matter volume of the human brain, using a longitudinal MRI Day2day dataset. Our analyses showed that aspects of image quality beyond visible motion artifacts had a significant impact on the results.

Wallas's Four Creativity Stages, Campbell's Two‐Stage BVSR, and the Three‐Criterion Definition of Creativity

open access: yesThe Journal of Creative Behavior, Volume 60, Issue 1, March 2026.
ABSTRACT The Wallas four‐stages and Campbell's two‐stage Blind‐Variation and Selective‐Retention (BVSR) represent two classic stage conceptions of creative thought. However, these two stage conceptions can be integrated by taking advantage of a quantitative definition of personal creativity, which is taken as the multiplicative product of originality ...

Crystal structure of carbon–nitrogen hydrolase from Helicobacter pylori G27

open access: yesActa Crystallographica Section F, Volume 82, Issue 3, Page 66-74, March 2026.
H. pylori carbon–nitrogen hydrolase was produced and crystallized, and its 2.1 Å resolution structure is reported.Carbon–nitrogen hydrolases (CNHs) are members of the diverse nitrilase superfamily of enzymes that facilitate cellular adaptation to environmental stress by metabolizing nitrogen, detoxifying xenobiotics and catabolizing environmentally ...
