The downward trajectory of plant and animal diversity constitutes a key issue of the Anthropocene. Whether diversity is changing also in the world of microbes is unknown, however -- a "profound ignorance" -- because the importance of these microorganisms maintain Earth's habitability. A paper published today frames the rate of change of microbial biodiversity as an important question on which progress is possible.
A new publication offers a comprehensive guide to help plant scientists communicate their work to the world. An Iowa State University scientist who contributed to the multi-institutional effort says it's critical that plant scientists emphasize outreach to make sure plant science is able to meet the demands of climate change and population growth.
One of the most comprehensive statistical analyses of drivers of food insecurity across 65 countries has concluded that household income consistently explains more discrepancy in food security than any other factor, including agricultural land resources and production.
Research in the Peruvian Andes highlights critical climate threats to montane forests and urges for current conservation plans to take climate projections into account.
According to a new study published today in the scientific journal Nature Communications, the oxygen content in the oceans will continue to decrease for centuries even if all CO2 emissions would be stopped immediately. According to the author, Prof. Dr. Andreas Oschlies, from GEOMAR Helmholtz Centre for Ocean Research Kiel, the slowdown of ocean circulation and the progressive warming of deeper water layers are responsible for this process.
A person who owns a car or who has a college education may be less vulnerable to COVID-19, according to an analysis of cases in Tehran, Iran, one of the early epicenters of the pandemic. While such variables do not inherently lower a person's risk, they do indicate an infrastructure of protection that persists despite how densely populated a person's district might be.
Brand asymmetries must be considered when applying cigarette tax hikes and smoke-free restrictions.
Researchers at Duke University have developed a method that uses machine learning, satellite imagery and weather data to autonomously find hotspots of heavy air pollution, city block by city block. The technique could be a boon for finding and mitigating sources of hazardous aerosols, studying the effects of air pollution on human health, and making better informed, socially just public policy decisions.
New research from Cornell and the University of Michigan offers the first comprehensive evidence that the city's adult residents suffered a range of adverse physical and mental health symptoms potentially linked to the crisis in the years during and following it, with Black residents affected disproportionately.
A new study builds on previous research found educating kids about the environment was linked to greater concern in their parents. Now, they have evidence kids can have an impact outside of their homes, too.
