DNA origami vaccine platform shows promise against multiple infectious viruses

The COVID-19 pandemic brought messenger RNA (mRNA) vaccines to the forefront of global health care. After their clinical trial stages, the first COVID-19 mRNA vaccine was administered on 8 December 2020 and mathematical models suggest that mRNA vaccines prevented at least 14.4 million deaths from COVID-19 in the first year alone.

Global study reveals how inequality limits access to exercise and why it matters for health

A global analysis of physical activity data from 68 countries shows large socioeconomic and gender inequalities in access to choice-based exercise, particularly active leisure. The study also synthesizes evidence linking physical activity to lower risks of severe infectious disease, depression, and cancer mortality, and proposes a new “physical activity for health and wellbeing” public health framework.

Study reveals why US life expectancy gains stalled after decades of progress

A PNAS study analyzing US mortality from 1979 to 2023 reveals that life expectancy stagnation reflects both worsening outcomes in post-1950 birth cohorts and a broad mortality deterioration beginning around 2010. Cardiovascular mortality slowdowns, rising external causes, and cohort-specific patterns help explain the persistent decline in longevity gains.

Study finds correlation between a state's sources of revenue and public-health policies

A new study in the United States finds that the more a state's budget relied on sales tax revenue, the more likely it was to shorten stay-at-home orders during the early stages of the COVID pandemic.

Building global standards for antimicrobial policy

Antimicrobial resistance (AMR) threatens human, animal, and environmental health globally. An international team from leading institutions, including the University of Edinburgh, London School of Hygiene and Tropical Medicine, North Carolina State University, and the International Centre for Antimicrobial Resistance Solutions, identifies fundamental gaps in current mathematical modelling approaches that prevent translation of science into policy, including data limitations, knowledge gaps about AMU-AMR relationships, and the absence of international coordination mechanisms similar to climate change efforts. They call for transdisciplinary collaboration to build integrated modelling architectures.

AI pinpoints why vaccine responses vary globally

How people with compromised immune systems respond to vaccines is an important area of immunological research. A new study led by York University found that not only could machine-learning models accurately pinpoint differences in healthy controls and those living with HIV, but also found outliers in both groups that provide fascinating glimpses into the complex nature of the immune system and what personalized medicine could look like in the future, accounting for variables such as age, comorbidities and genetics.
