Collaboration Between Host and Viral Factors Shape SARS-CoV-2 Evolution

This study investigates how viral and host factors influence SARS-CoV-2 evolution in vitro, identifying genetic changes and their impact on viral fitness in different cell types.

Sexual selection for males with beneficial mutations

This study shows that female preference for males with beneficial mutations enhances genetic quality more than preference for low mutational load, potentially explaining the prevalence of sexual reproduction.

Drift as a driver of language change: An artificial language experiment

This study tests hypotheses about language change by experimentally manipulating drift and selection in an artificial language task, finding drift alone can explain regularization of low-frequency words.

HPF1 and nucleosomes mediate a dramatic switch in activity of PARP1 from polymerase to hydrolase

This study investigates how HPF1 modulates PARP1 activity, switching it from polymerase to hydrolase, and shows HPF1's role in redirecting PARylation and affecting PAR chain length.

In vitro assessment of the virucidal activity of four mouthwashes containing Cetylpyridinium Chloride, ethanol, zinc and a mix of enzyme and proteins against a human coronavirus

This study assesses the virucidal activity of four mouthwashes against a human coronavirus surrogate, finding that 0.07% Cetylpyridinium Chloride mouthwash reduces viral counts by ≥3.0 log.

What we talk about when we talk about color

The paper quantifies communicative needs for colors across 130 languages and finds non-uniform demand, correlating with salient objects and geographic factors.

Comparative primary paediatric nasal epithelial cell culture differentiation and RSV-induced cytopathogenesis following culture in two commercial media.

This study compares two commercial media for culturing primary nasal epithelial cells and evaluates their impact on cell morphology, physiology, and RSV infection outcomes.

Helping those who help others for indirect fitness benefits not indirect reciprocity

The paper argues that helping those who help others can be explained by indirect fitness benefits and relatedness, not just indirect reciprocity, and suggests that image scores may be important for cooperation.

Honest signalling of trustworthiness

The paper develops a theory that reputation building signals trustworthiness and shows that costly helping behavior evolves as an honest signal when cooperators gain greater benefits from reputation than defectors.

Bridging of nucleosome-proximal DNA double-strand breaks by PARP2 enhances its interaction with HPF1

The paper presents a cryo-EM structure of PARP2 bridging nucleosome-proximal DNA breaks and shows its interaction with HPF1 in a functional complex.

First report on the effective intraperitoneal therapy of insulin-dependent diabetes mellitus in pet dogs using \"Neo-Islets\", aggregates of adipose stem and pancreatic islet cells

This paper reports on the use of Neo-Islets in pet dogs to treat insulin-dependent diabetes, achieving improved glycemic control without immunosuppression or encapsulation.
