Human extracellular matrices can be edited in their composition using the CRISPR/Cas9 system, leading to materials exhibiting tailored regenerative capacities.

Equations generalizing reward rate maximization are derived, explaining ostensible suboptimal behaviors, revealing time’s cost to comprise apportionment and opportunity costs, and identifying the ...

This study presents a valuable open-source and cost-effective method for automating the quantification of male aggression and courtship in Drosophila melanogaster. The work as presented provides solid ...

Transgenic animals continue to play an essential role in many aspects of zebrafish research, including the development of disease models. The most widely used system for zebrafish transgenesis is the ...

This important research addresses the effects of subjective control and task difficulty on experienced stress using a novel behavioral task in two, large online samples. Convincing evidence is ...

Researchers have characterised how dying, or necrotic, cells contribute to the body’s regeneration process, with potential implications for wound and tissue repair.

A Congressional Science & Technology policy fellow outlines some options available for responding to the blatant attacks on science and the scientific workforce in the US.

Methods: To study accessibility and reproducibility in cardiovascular research reporting, we screened 639 randomly selected articles published in 2019 in three top cardiovascular science publications: ...

New results help address a longstanding debate regarding which learning strategies allow animals to anticipate negative events based on past associations between sensory stimuli.

This potentially important model-based study seeks to mimic bat echolocation behavior and flight under high-density conditions. The simulations convincingly suggest that the problem of acoustic ...

The authors' demonstration that impaired olfactory perception reduces caterpillar performance and increases susceptibility to parasitism is solid. These findings highlight the ecological significance ...

A new study has revealed how hunger influences dietary decisions by shifting attention towards tastier, but less healthy, food options.
