Optimizing website performance: A comprehensive Google Lighthouse study on desktop and mobile modes

In this study, we examined the consistency and dependability of Google's Lighthouse tool for measuring website performance, accessibility, SEO, and best practices. Tests conducted on three websites showed that performance scores vary based on the testing mode and website complexity, while other audit categories stay constant. These results provide direction for researchers and developers by highlighting Lighthouse's benefits and drawbacks.

Galaxy clusters offer several advantages for measuring H0 compared to traditional methods, such as Cepheid variables or Type Ia supernovae. Unlike individual stars or supernovae, clusters are less affected by local variations in stellar population or interstellar medium properties, providing a more stable and consistent measure over large cosmological distances. This work proposes using galaxy clusters as an alternative method for determining the H0. It provides an independent perspective on the H0 debate and contribute to ongoing efforts to reconcile the differing values obtained from the other two measurements.

Multi-omic analysis identifies mitochondrial dysfunction as a key feature of hypertrophic cardiomyopathy

This study used multi-omic analysis to investigate gene expression and DNA methylation patterns associated with hypertrophic cardiomyopathy (HCM). The researchers found significant downregulation of mitochondrial and energy-related pathways, highlighting mitochondrial dysfunction—particularly altered PINK1 expression—as a potential contributor and therapeutic target in HCM.

In vitro effects of cosmetic products on the growth of skin-resident bacteria

Relia et al. | Sep 20, 2026

<i>In vitro</i> effects of cosmetic products on the growth of skin-resident bacteria

This study investigated how 18 commonly used cosmetic products affect the growth of two skin-resident bacteria, Staphylococcus epidermidis and Micrococcus luteus. At higher concentrations, half of the tested products inhibited at least one bacterial species, suggesting that some cosmetics may disrupt the skin microbiome and its natural balance.
