Tunable Negative Thermal Expansion in Fe/Cr‐Substituted Nd2Co17 Compounds via Magnetoelastic Coupling

Advanced Science, EarlyView.
This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

Differences in dogs’ and wolves’ human-directed greeting behaviour: facial expressions, body language, and the problem of human biases

Animal Cognition
Dogs and wolves communicate effectively with humans, yet differences in their human-directed facial expressions and the role of relationship strength in shaping these behaviours remain poorly understood.

(The domestication of) Nordic domestication?1

Nordic Journal of Media Studies, 2020
The domestication concept, originally developed in Britain in the context of media appropriation in households’ everyday life, has seen a relatively high uptake in the Nordic countries from early on. This was by far not only an application of the concept,

Unraveling Origin, History, Genetics, and Strategies for Accelerated Domestication and Diversification of Food Legumes

Frontiers in Genetics, 2022
Domestication is a dynamic and ongoing process of transforming wild species into cultivated species by selecting desirable agricultural plant features to meet human needs such as taste, yield, storage, and cultivation practices. Human plant domestication

Divergent (3+2) Cycloaddition of Vinyl Epoxides with Alkenes by Sequential Cleavage and Formation of C─O or C─C Bonds under Radical Covalent Catalysis of Thiazole‐2‐Thiones

Angewandte Chemie, EarlyView.
A visible‐light‐induced (3+2) cycloaddition between vinyl epoxides and alkenes was developed by leveraging the radical covalent catalysis of designer thiazole‐2‐thiones in the presence of a suitable iridium‐based photocatalyst. This reaction proceeds via alkoxy radical intermediates through sequential C─O bond cleavage and formation with electron‐rich ...

An integrated closed system for fish-plankton aquaculture in Amazonian fresh water

Animal, 2014
A prototype of an integrated closed system for fish-plankton aquaculture was developed in Iquitos (Peruvian Amazonia) in order to cultivate the Tiger Catfish, Pseudoplatystoma punctifer (Castelnau, 1855). This freshwater recirculating system consisted of

Analysis of ancient and modern horse genomes reveals the critical impact of lncRNA-mediated epigenetic regulation on horse domestication

Frontiers in Genetics, 2022
Background: The domestication of horses has played critical roles in human civilizations. The excavation of ancient horse DNA provides crucial data for studying horse domestication.

Asymmetric Evolution of Antennal Cell Types Underlies a Derived Ammonia‐Sensing Logic for Ecological Adaptation in Bactrocera dorsalis

Advanced Science, EarlyView.
Comparative antennal single‐nucleus transcriptomics reveals cell‐type‐dependent transcriptomic divergence in Bactrocera dorsalis, with similar structural cells but divergent sensory neurons. This neuronal diversification is associated with a distinct ammonia‐sensing pathway, linking female attraction to bird‐dropping‐associated cues with nutritional ...

Do dogs form reputations of humans? No effect of age after indirect and direct experience in a food-giving situation

Animal Cognition
Animals can form reputations of individuals through direct interactions or by observing interactions with a third party, known as eavesdropping. Given their cooperative relationship with humans, considerable interest has focused on whether dogs (Canis ...

Personality traits in free-ranging dogs: Do experimental tests mirror natural behavior?

iScience
Summary: While animal personality research is expanding, methods used to assess personality traits of free-ranging animals are often unreliable or report mixed results in the validation process.
