David couldn't bring down Goliath: museum specimen reveals a failed predation attempt by fire ants ( Westwood, 1840) upon a large hawk moth (Cramer, 1775).

Insights into insect predatory behaviour can be inferred indirectly from specimens housed in Natural History Collections. In this work, we document a unique interaction, never recorded before, involving the remains of a Westwood, 1840 ant worker -probably (Smith, 1855)- whose head is firmly attached by its mandibles to an antenna of a female hawk moth (Cramer, 1775) (Sphingidae). This specimen is part of the Entomology Collection at the MNCN-CSIC in Madrid, Spain.

Multi-omics profiling reveals altered mitochondrial metabolism in adipose tissue from patients with metabolic dysfunction-associated steatohepatitis.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) and its more severe form steatohepatitis (MASH) contribute to rising morbidity and mortality rates. The storage of fat in humans is closely associated with these diseases' progression. Thus, adipose tissue metabolic homeostasis could be key in both the onset and progression of MASH.

Antiracist activism for immigrant rights and healthy coping: Initial evidence for a community-based framework.

Racist and xenophobic policies in the United States (e.g., family separations and lack of access to protected immigration statuses for undocumented immigrants) have historically excluded immigrants of color from accessing full civil rights, thus contributing to widening racial inequities in the US.

[Stratégies pour la mise en place d'un chœur intergénérationnel dans une résidence pour personnes aînées afin de contribuer à leur bien-être physique, mental et social].

Dans le contexte pandémique de la COVID-19, les personnes aînées se sont retrouvées confinées et isolées, et ce, même dans le cadre d'un milieu de vie collective. Cet article fait état d'une étude de la portée sur les bienfaits d'un chœur intergénérationnel pour personnes aînées et les stratégies à considérer pour sa mise en place. L'analyse de 16 études sur ce sujet a permis de se familiariser avec les résultats, les recommandations et les pistes de recherche en lien avec le bien-être et le sens de satisfaction que retirent les personnes aînées qui participent à un chœur, de même que des interventions en chant choral à privilégier.

Voluntary activation of maximal single and all finger power grip contractions.

When all four fingers are engaged together during a grip strength contraction, the force produced by an individual finger is less than the force produced when it acts in isolation. The purpose of this study was to evaluate whether the reduced force output of a digit during an all-finger grip contraction is due to a decline in voluntary activation. Fifteen young adults ( = 7 females) completed voluntary contractions of the index finger in isolation and all fingers together in a dynamometer capable of separately recording forces from each finger during voluntary and electrically evoked contractions.
