A new approach to genomic species delineation could impact policy and lend clarity to legislation for designating a species as endangered or at risk. Evolutionary biologists model the process of speciation, which follows population formation, improving on current species delineation methods.
A group of the world's leading experts in the transmission of airborne pathogens is calling for a tightened regulatory system to control air quality in buildings - as a way of reducing the spread of covid-19 and other illnesses.
QUT air-quality expert Distinguished Professor Lidia Morawska is leading an international call for a "paradigm shift" in combating airborne pathogens such as COVID-19, demanding universal recognition that infections can be prevented by improving indoor ventilation systems.
Parks played an important role for people seeking respite from the toll of social isolation during the pandemic, and according to new research from Drexel University, they did so without increasing the spread of COVID-19. The study looked at how people used 22 parks in Philadelphia and New York during the height of the pandemic and it found no strong correlation between park use and the number of confirmed cases in surrounding neighborhoods.
The research offers some of the first clear guidance on the most effective methods to perform testing to detect COVID-19 in wastewater.
It was commonly assumed that wildlife products are exported from low-income countries to meet the demand of consumers in wealthy economies, and therefore, a widening wealth gap may drive up the volume of global trade and endanger wildlife. Recently, a research team co-led by the University of Hong Kong and Lingnan University corroborated this premise by analysing global wildlife trade databases. The findings are published in Science Advances.
A new study from the University of Portsmouth calls for further government oversight to curb potential illegal activity through these zones.
A new paper in the Journal of the European Economic Association indicates that distrust generated by a 2011 CIA-led vaccination campaign ruse designed to catch Osama Bin Laden resulted in a significant vaccination rate decline in Pakistan.
MIT political scientist Evan Lieberman is co-author of a new paper showing mixed reactions when people are informed of the racial disparities in Covid-19 outcomes in the U.S.
Twenty dollars a month might not seem like a lot to pay for health insurance. But for people getting by on $15,000 a year, it's enough to make some drop their coverage - especially if they're healthy, a new study of Medicaid expansion participants in Michigan finds. That could keep them from getting preventive or timely care, and could leave their insurance company with a sicker pool of patients than before.
