Bistable Networks Enable Complex Shape Changes

open access: yesAdvanced Science, EarlyView.
Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

Lateralization of eye use in cuttlefish: opposite direction for anti-predatory and predatory behaviors.

open access: yesFrontiers in Physiology, 2016
Vertebrates with laterally placed eyes typically exhibit preferential eye use for ecological activities such as scanning for predators or prey. Processing visual information predominately through the left or right visual field has been associated with ...

Electron compensation‐gated nanomotor for immunomodulation and microenvironment remodeling in bacterial pneumonia therapy

open access: yesBMEMat, EarlyView.
A nanomotor featuring an “electronic lock” via electron compensation in an Au‐Ag alloy ensures therapeutic precision. Near‐infrared light acts as a key, unlocking on‐demand Ag+ release for synergistic bactericidal action and microenvironment remodeling to potently treat bacterial pneumonia. Abstract Bacterial pneumonia treatment is severely hampered by

False memories in cuttlefish

open access: yesiScience
Episodic memory is a reconstructive process per se, which means that during an event, the features composing it are encoded and stored separately in the brain, then reconstructed when the event’s memory is retrieved. However, because of this reconstruction, and even with processes monitoring the reliability of the memory such as source memory (e.g. did

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Optimising Sulphur Fertilisation in Ryegrass–White Clover Swards Reduces Leached Nitrate Nitrogen Losses, While Increasing Plant Yield and Nitrogen Off‐Take

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
The inclusion of sulphur at two inorganic nitrogen rates (0 and 150 kg N ha−1) improves plant productivity in a ryegrass–white clover sward and reduces nitrate‐N loss to groundwater in a free‐draining sandy loam soil. ABSTRACT Background Reducing nitrogen (N) losses to water, lessening reliance on inorganic fertiliser and maintaining agricultural ...

Studies on chemical composition of cuttlefish (Sepia sp.) meat as related to its nutritive value [PDF]

open access: yesActa Ichthyologica et Piscatoria, 1970
The chemical composition of edible cuttlefish flesh, distinguishing it into the mantle and arms together with part of head was examined. Comparison between the chemical composition of cuttlefish flesh and that of squid, originating from the same fishing ...

Microbial communities and functional diversity in seafood

open access: yesJSFA reports, EarlyView.
Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

Antibacterial Activity of Cuttlefish Sepia sp. (Cephalopoda,) Ink Extract Against Aeromonas hydrophila

open access: yesMajalah Obat Tradisional, 2019
Cephalopods ink has shown potential antiretroviral activity. The ink extracts of cuttlefish showed an antibacterial effect. This study aims to investigate the antibacterial activity of the methanolic extract of the ink of cuttlefish Sepia sp.

Differentiation between Fresh and Thawed Cephalopods Using NIR Spectroscopy and Multivariate Data Analysis

open access: yesFoods, 2021
The sale of frozen–thawed fish and fish products, labeled as fresh, is currently one of the most common and insidious commercial food frauds. For this reason, the demand of reliable tools to identify the storage conditions is increasing.
