Inoculation reduces social media engagement with affectively polarized content in the UK and US.
Commun Psychol

School of Psychological Science, University of Bristol, Bristol, UK.
The generation and distribution of hyper-partisan content on social media has gained millions of exposure across platforms, often allowing malevolent actors to influence and disrupt democracies. The spread of this content is facilitated by real users' engaging with it on platforms. The current study tests the efficacy of an 'inoculation' intervention via six online survey-based experiments in the UK and US.

Air-pollution monitoring is sparse across most of the United States, so geostatistical models are important for reconstructing concentrations of fine particulate air pollution (PM) for use in health studies. We present XGBoost-IDW Synthesis (XIS), a daily high-resolution PM machine-learning model covering the contiguous US from 2003 through 2023. XIS uses aerosol optical depth from satellites and a parsimonious set of additional predictors to make predictions at arbitrary points, capturing near-roadway gradients and allowing the estimation of address-level exposures.

Background: Pneumococcal conjugate vaccines (PCVs) introduced in childhood national immunization programs lowered vaccine-type invasive pneumococcal disease (IPD), but replacement with non-vaccine-types persisted throughout the PCV10/13 follow-up period. We assessed PCV10/13 impact on pneumococcal meningitis incidence globally.
Methods: The number of cases with serotyped pneumococci detected in cerebrospinal fluid and population denominators were obtained from surveillance sites globally.
Optical assessment of heroin using laser-induced fluorescence spectroscopy based on modified Beer-Lambert formalism.

Heroin as a derivative of morphine contains the alkaloids and flavonoids with plenty of three to five aromatic rings. The latter is known as the main source of fluorescence emission after laser excitation. Here, laser induced fluorescence (LIF) spectroscopy at excitation line of 405 nm with the solvent densitometry method is introduced based on modified Beer-Lambert (MBL), for the rapid and reliable identification of street heroin samples.

Barley (Hordeum vulgare L.) is an important cereal crop used in animal feed, beer brewing, and food production. Waterlogging stress is one of the prominent abiotic stresses that has a significant impact on the yield and quality of barley.
