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.
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.
Snow cover in the Alps has been melting almost three days earlier per decade since the 1960s. This trend is temperature-related and cannot be compensated by heavier snowfall. By the end of the century, snow cover at 2,500 meters could disappear a month earlier than today, as simulations by environmental scientists at the University of Basel demonstrate.
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.
Artificial intelligence (AI) has sped up the process of detecting flooded buildings immediately after a large-scale flood, allowing emergency personnel to direct their efforts efficiently. Now, a research group from Tohoku University has created a machine learning (ML) model that uses news media photos to identify flooded buildings accurately within 24 hours of the disaster.
Thirdhand smoke is created when exhaled smoke and smoke emanating from the tip of burning cigarettes settles on surfaces such as clothing, hair, furniture, and cars. A team led by scientists at the University of California, Riverside, has found chemicals in THS get extracted more readily from household fabrics in a humid environment than in a dry one.
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.
Agricultural producers deal firsthand with changing weather conditions, and extreme events such as drought or flooding can impact their productivity and profit. Climate change models project such events will occur more often in the future. But studies of the economic consequences of weather and climate on agriculture typically focus on local impacts only.
