Transparent and Robust LiCl–Organohydrogel Triboelectric Nanogenerator With Deep Learning Assisted Sensing

Advanced Functional Materials, EarlyView.
Develop a LiCl–PEI–PAM hydrogel with 3000% stretchability and excellent optical transparency. Through comparative studies of various salts, confirm that LiCl is the most suitable salt for high TENG output. Achieve excellent freeze‐resistant, dry‐resistant, and rapid self‐healing (10 s) properties even in extreme environments. Balance ionic conductivity,

Microgel‐Based 3D Bioprinting: A Convergent Strategy Integrating Material Design, Jamming Dynamics, and Biological Function

Advanced Healthcare Materials, EarlyView.
Microgel‐based 3D printed constructs represent a compelling and versatile innovation for engineering architecturally complex, dynamically remodelable, and biocompatible structures with high structural fidelity and bioactivity. By integrating material design, biofabrication, and biological function, these systems enable the development of adaptive ...

Learned kin recognition cues in a social bird

, 2005
In many cooperatively breeding birds, kin selection has an important role in the evolution and maintenance of social behaviour, and 'helpers' can maximize indirect fitness gains by preferentially allocating care to close relatives.

Counterintuitive Fluorescence Blue Shift in Symmetry Breaking Dicationic Bis(indolium) with Two‐Photon Absorption Properties for NIR Living Cell Imaging

Advanced Materials, EarlyView.
Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.

Assembling a True “Olympic Gel” From over 16 000 Combinatorial DNA Rings

Advanced Materials, EarlyView.
Olympic gels are an elusive class of soft matter, consisting of molecular networks held together purely by mechanically interlocked rings. Their topological structure promises unique properties and functions, but their synthesis has proven notoriously difficult.

Kin discrimination in tadpoles of Hylarana temporalis (Anura: Ranidae) and Sphaerotheca breviceps (Anura: Dicroglossidae) hydroperiod and social habits

Phyllomedusa: Journal of Herpetology, 2014
Kin discrimination ability was studied in tadpoles of Hylarana temporalis and Sphaerotheca breviceps, which live in two distinctly different habitats; the former shows social aggregation and the latter live scattered. Early in development, tadpoles of H.

An empirical study of the evolutionary significance of cannibalism in tree-hole mosquitoes (Diptera : Culicidae) from ecological and biological perspectives [PDF]

, 1995
To be adaptive, optimality theory suggests that behavioural traits should maximise the fitness of the carrier by spread of genotypes through a population.

Actuation of Cell Layers in Three Dimensions

Advanced Materials, EarlyView.
ABSTRACT The alignment of fibers and cells in living tissues affect their mechanical properties and functionality. In this context, one can draw an analogy between tissues and nematic liquid crystal elastomers. We explore this analogy by growing fibroblasts on 2D‐patterned substrates and observing the contraction of cell sheets upon detachment from the

A Highly Polymorphic Receptor Governs Many Distinct Self-Recognition Types within the Myxococcales Order

mBio, 2019
Self-recognition underlies sociality in many group-living organisms. In bacteria, cells use various strategies to recognize kin to form social groups and, in some cases, to transition into multicellular life. One strategy relies on a single genetic locus

Social evolution: the decline and fall of genetic kin recognition.

, 2007
Animals should benefit from the ability to recognise their kin, yet curiously this faculty is often absent.
