Phytochromes facilitate social behaviour in marine diatoms

Nature Communications
The phytochrome superfamily comprises photosensory proteins that enable organisms to perceive changes in light intensity and quality and is widespread across plants, fungi, algae, and microbes.

Glass-crystallized far-red-emitting ceramics for high-power, spectrally matched plant-growth light sources

Journal of Advanced Ceramics
High-brightness far-red light plays a key role in increasing photosynthetic efficiency and thus crop production in plant factories, as it regulates the entire lifecycle of plants, from seed germination to flowering and fruiting.

Advancing SafeWax, A Bio‐Inspired Superhydrophobic Coating, Toward Sustainable and Climate‐Resilient Crop Protection

Advanced Functional Materials, EarlyView.
This study advances SafeWax, a bio‐inspired, fatty‐acids‐based superhydrophobic coating, by identifying an agriculturally compliant solvent and revealing how solvent‐controlled Fatty acid crystallization governs the coating's microscopic structure and performance.

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots

Advanced Functional Materials, EarlyView.
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

The Effects of Blue Light and Supplemental Far-Red on an In Vitro Multiple Harvest System for the Production of Cannabis sativa

Plants
Blue and supplemental far-red light were observed to affect in vitro shoot growth with Cannabis sativa (‘BaOx’ and ‘Cherry 1’) in RV750 vessels. A modified “hedging” and fed-batch system for multiple harvests using Oasis® foam and 120 mL DKW medium was ...

Photoconversion and Nuclear Trafficking Cycles Determine Phytochrome A's Response Profile to Far-Red Light

, 2011
SummaryPhytochrome A (phyA) is the only photoreceptor in plants, initiating responses in far-red light and, as such, essential for survival in canopy shade.

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

Advanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

ATP‐Mediated Bidirectional Communication Between Natural and Artificial Cells for Controlled Bioreactions

Advanced Functional Materials, EarlyView.
Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...

Structure of a stripped-down and tuned-up far-red phycobilisome

Communications Biology
A diverse subset of cyanobacteria can transiently modify their photosynthetic machinery during far-red light photoacclimation to drive photosynthesis with less energetic photons (700 nm–800 nm).

Concentration‐Dependent Self‐Assembly and Nanoparticle Maturation of Reflectins

Advanced Functional Materials, EarlyView.
Within squid skin, structural coloration arises from iridophores whose Bragg reflector‐like ultrastructures contain high‐refractive‐index reflectin proteins. Coarse‐grained molecular dynamics simulations and dynamic light scattering measurements reveal how concentration modulates reflectin A2 self‐assembly.
