Peptide Electrostatic Modulation Directs Human Neural Cell Fate

open access: yesAdvanced Science, EarlyView.
This study explores the effect of charge on the bioactivity of peptide‐based supramolecular materials. The design of a peptide library with varying charges that self‐assemble into supramolecular fibers is presented, demonstrating how the surface charge of these fibers, used as artificial extracellular matrices, influences the fate of human neural ...

Tuning Exciton Dynamics and Energy Transfer in Ternary Organic Solar Cells Using Pyridine‐Flanked DPP Acceptors

open access: yesAdvanced Energy Materials, EarlyView.
Three novel non‐fullerene acceptors with a DPP–pyridine‐based structure have been studied, each incorporating different π‐bridging units. LM‐Se exhibited the highest efficiency among the NFAs, and its incorporation into a ternary blend with D18 and Y6 (PCE = 17.53%) significantly enhanced performance due to improved charge dynamics and favorable film ...

Heat drastically alters floral color and pigment composition without affecting flower conspicuousness

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

Biallelic Variants in the DARS2 Gene as a Novel Cause of Axonal Charcot–Marie–Tooth Disease

open access: yesAnnals of Neurology, EarlyView.
Objective Charcot–Marie–Tooth (CMT) disease is a heterogeneous group of genetic neuropathies, with >90 genes identified. Several aminoacyl‐tRNA synthetases have been linked to CMT. DARS2, encoding the mitochondrial aspartyl‐tRNA synthetase, has been typically associated with leukoencephalopathy with brainstem and spinal cord involvement and lactate ...
