A new study finds that most US parents intend to vaccinate their infants and young children against COVID-19, influenza, and respiratory syncytial virus (RSV), with 40% planning to vaccinate against COVID-19. The study also highlights the growing concern of vaccine hesitancy and its potential impact on public health.
A recent study found that successive waves of migrations from Western Anatolia, central and northern Europe, and the Pontic-Kazakh Steppe shaped the Balkan population during the Roman Empire's reign. The influx of Slavic-speaking populations resulted in present-day residents having 30%–60% Slavic ancestry.
A study by UNIGE researchers found that six psychological interventions had a small and temporary impact in preventing the spread of climate misinformation. The interventions targeted factors such as trust in climate scientists, transparency, and accuracy, but only one group showed a slight advantage in resisting disinformation.

The projects will explore innovative implementation strategies to enhance community engagement and support high-quality services.
A study published in PLOS ONE found correlations between climate change and human population trends in Central European regions. During warm periods, populations increased due to improved crops and economies, while during cold periods, populations decreased, leading to cultural shifts and potential social inequality.
The study analyzed genome sequences from two skull fragments dated to 36,000 and 37,000 years ago, revealing genetic proximity to current and ancient Europeans. The findings suggest that these individuals contributed to the population that gave rise to the Gravettian culture around 5,000 years later.

A new study by researchers at UC Irvine and the University of Arizona found no consistent relation between COVID-19-related jail decarceration and violent or property crime in California. The study suggests that downsizing, on average, did not drive crime increases statewide, but notes limitations such as a short measurement period.
A recent study published in The Journals of Gerontology – Series B found that having more children can produce economic, social, emotional, and biological burdens that impact health, especially chronic conditions and depression. In contrast, adults with fewer children were more likely to report poor self-rated health in certain countries.
A study of over 13 million US infants found maternal Medicaid insurance associated with higher infant mortality rates. Novel strategies are needed to improve outcomes among women and infants enrolled in Medicaid.
Research reveals that the illegal killing of orangutans on Borneo remains a significant threat to the species, with 30% of villages reporting killings in the last 5-10 years. Conservation efforts may not be effectively preventing killing and addressing human-orangutan conflict is crucial.

The study, which analyzed data from over 2 million adults in Wales, highlights the need for improved public green spaces to address mental health inequalities.
A new UC Davis study investigates the complex mix of attitudes and concerns about the state of democracy in the US. While most respondents reject political violence altogether, some believe it is usually or always justified to advance political objectives.
New research finds that cigarette smoking increases the risk of developing type 2 diabetes by affecting various metabolites in the bloodstream. A unique metabolic signature, identified through analysis of over 93,000 UK Biobank participants, can predict which smokers are more likely to develop the condition.
Moderately sized groups of hominins may have successfully scavenged carcasses, even competing with giant hyenas, according to a new study. The research suggests that scavenged remains were an important source of meat and fat for early humans.

A new study by Yale researchers found that despite reductions in fine particulate air pollution, racial and ethnic minorities still experience disproportionately high rates of cardiovascular disease-related deaths. The study found that Black people face the highest burden, with a mortality rate 4.59 times higher than white people in 2001.
Patients with cancer had disparate COVID-19 mortality rates during the winter Omicron wave compared to the general US population. The study suggests that immune-evasive SARS-CoV-2 variants pose a significant threat, requiring prioritized efforts to prevent transmission.
A new essay highlights how news stories about healthcare workers during COVID-19 often left out crucial socioeconomic and environmental contexts, which can impact consumer thoughts and responses. By introducing a public health framework, experts aim to broaden storytelling and reframed scientific information dissemination.
