Genomic signatures of adaptation in native lizards exposed to human-introduced fire ants.

Understanding the process of genetic adaptation in response to human-mediated ecological change will help elucidate the eco-evolutionary impacts of human activity. In the 1930s red imported fire ants (Solenopsis invicta) were accidently introduced to the Southeastern USA, where today they are both venomous predators and toxic prey to native eastern fence lizards (Sceloporus undulatus). Here, we investigate potential lizard adaptation to invasive fire ants by generating whole-genome sequences from 420 lizards across three populations: one with long exposure to fire ants, and two unexposed populations.

GDF15 antagonism limits severe heart failure and prevents cardiac cachexia.

Aims: Heart failure and associated cachexia is an unresolved and important problem. This study aimed to determine the factors that contribute to cardiac cachexia in a new model of heart failure in mice that lack the integrated stress response (ISR) induced eIF2α phosphatase, PPP1R15A.

Methods And Results: Mice were irradiated and reconstituted with bone marrow cells.

Corrigendum: Cigarette smoke restricts the ability of mesenchymal cells to support lung epithelial organoid formation.

CT features associated with contralateral recurrence of spontaneous pneumothorax.

Introduction: Spontaneous pneumothorax recurs in 30 to 54% of patients without surgery. Identifying individuals likely to suffer a recurrence, who might benefit from pre-emptive surgery, is challenging. Previous meta-analysis suggested a relationship between contralateral recurrence and specific computed tomography (CT) findings.
