According to a new study, monitoring fungal spores in the outdoor air can predict surges in flu and COVID-19 infections.

In a Policy Forum, Jessica Espey and colleagues argue that waning support for accurate collection and curation of population data worldwide threatens to compromise crucial evidence-based government planning. “We live in an era of seemingly unlimited data, where our digital activities may generate nearly constant information streams, yet some of our most essential infrastructure – demographic information – is deteriorating, introducing known and unknown bias into decision-making,” write the authors. Accurate population data are fundamental to effective governance. Most countries rely on national censuses, which are traditionally conducted every 10 years, to supply this information. But according to Espey et al., fewer nations are completing censuses, and many are undercounting marginalized populations. For example, at the close of the 2020 census cycle, 204 countries or territories – encompassing 85% of the world’s population – had conducted at least one census between 2015 and 2024. Yet by July 2024, 24 of these, representing roughly one-quarter of the global population, had not published their findings. This reflects a significant decline from the 2010 round, when 214 countries conducted and released census data, encompassing 93% of the global population. Moreover, even when censuses are carried out, they increasingly suffer from declining response rates and growing coverage errors – particularly in the undercounting of vulnerable populations such as ethnic minorities and young children. In the United States, for instance, the 2020 census likely missed nearly 3 million Latino individuals and close to 1 million children under the age of five.

 

In this Policy Forum, the authors outline several reasons for this general decline: eroding trust in institutions, COVID-19 disruptions, budget cuts to statistical offices, and collapsing international support for data collection programs. In order to address this “quiet crisis,” Espey et al. suggest adopting register-based systems, harnessing geospatial technologies and AI, and producing small-area population estimates. However, technical innovations alone are not enough, note the authors; governments must also restore public trust by showing how data informs daily life, ensuring strong privacy protections, and promoting collaboration across sectors. “In an era of growing challenges, from climate change to economic inequality, accurate population data are not a luxury – they are essential infrastructure for healthy, resilient, functioning societies,” write the authors.

A new lateral-flow test could one day save lives across the world through early detection of a deadly fungal disease which dramatically spiked during the COVID-19 pandemic.

Key findings

• This study revealed that >70% of workers with continuous positive airway pressure (CPAP) using changed their work style to telecommuting, resulting in decreased physical activity, and commuters tended to have shorter durations and lower rates of CPAP use compared to teleworkers.

What is known and what is new?

• The coronavirus disease 2019 pandemic has resulted in many lifestyle changes. However, no studies have reported how these factors affect obstructive sleep apnea patients undergoing CPAP treatment.

• Our study investigated the impact of lifestyle changes on CPAP users during Japan’s first state of emergency. Over 50% of CPAP users who were employed changed their work style, leading to reduced physical activity. Commuters showed shorter durations and lower adherence to CPAP therapy compared to teleworkers.

What is the implication, and what should change now?

• We provided important data on lifestyle changes during the coronary pandemic period for CPAP users. Further randomized controlled studies are needed to confirm these findings.

New research by ESMT Berlin and Politecnico di Milano explores how non-experts assess scientific research proposals and reveals key implications for public participation in science funding. The study shows that while citizens value both social impact and scientific merit, their judgments can be shaped by personal interests, income, and education. The paper, published in Research Policy, is co-authored by Henry Sauermann (ESMT Berlin), Chiara Franzoni, and Diletta Di Marco (both of Politecnico di Milano). It involved more than 2,300 citizen evaluators who assessed four real research proposals using both a recommendation mechanism (advising a funding agency) and a crowdfunding mechanism (donating their own money). The proposals covered a diverse range of topics including COVID-19 drug discovery, Alzheimer’s, otter-human conflict in Florida, and economic preferences across demographic groups. 

Vaccinated patients hospitalized with COVID-19 who developed acute kidney injury had better outcomes than unvaccinated patients with the same condition. Vaccinated patients were less likely to stay on dialysis after discharge, and more likely to survive, than unvaccinated patients.

In a new study from Boston University Chobanian & Avedisian School of Medicine, researchers have identified a protein called non-structural protein 15 (nsp15) that plays a key role in helping SARS-CoV-2 hide from the body’s defenses by suppressing the production of viral double-stranded (dsRNA), leading to increased viral replication while limiting the body’s immune response.

By creating a cohesive AI-enabled and physics-based molecular modeling and drug discovery pipeline built around film industry animation software, researchers at the Wyss Institute at Harvard University identified the orally available, FDA-approved drug bemcentinib, as a potential antiviral agent. They then used this chemical compound as a launch pad for developing a more specific and effective antiviral drug with efficacy against a broad range of coronaviruses, which has great potential for fighting future respiratory pandemics. 

The use of complementary and alternative medicine (CAM) has remained fairly steady across Europe over the past decade. However, significant disparities exist between countries.

Contrary to expectations, the Covid pandemic did not cause a spike in the overall use of CAM in Europe: the growth was modest, from 27% in 2014 to 28% in 2023. These University of Helsinki findings are reported in an article published in the Journal of Public Health.

UK-ROX, the largest ever clinical trial of oxygen use in UK intensive care units (ICUs), has shown that reducing supplementary oxygen does not deliver any clear and obvious health benefits or harm a patient's chances of survival. Each year, around 184,000 patients are admitted to ICUs, but there is insufficient evidence to guide the use of oxygen, with the possibility that administering too much - or too little - may not deliver the intended benefits and actually end up causing patients additional harm. UK-ROX, led by the University of Plymouth and the Intensive Care National Audit & Research Centre, set out to fill that evidence gap and the results have been presented to delegates at the Critical Care Reviews Meeting 2025 in Belfast this morning, and published in the JAMA journal.

About The Study: In this cross-sectional study using data from the Centers for Disease Control and Prevention Wide Ranging Online Data for Epidemiologic Research database, alcohol-associated liver disease mortality increased significantly across demographic groups, with particularly concerning trends among women, younger adults, and American Indian and Alaska Native populations. These findings highlight the urgent need for targeted public health interventions and enhanced surveillance, especially given the sustained impact of COVID-19 pandemic–related changes in alcohol consumption patterns.
