Cryptocurrencies have been treated as a financial terra incognita -- they enjoyed growing interest but also raised concerns due to their virtuality. The use of statistical methods utilizing correlation matrices to analyze the hundred most-traded virtual currencies shows that the cryptocurrency market in the last two years is less and less different from the mature global currency market (Forex) and becomes independent of it. It means cryptocurrencies can be considered a serious and full-fledged financial instrument.
The risk for violent clashes increases after weather extremes such as droughts or floods hit people in vulnerable countries, an international team of scientists finds. Vulnerable countries are characterized by a large population, political exclusion of particular ethnic groups, and low development. The study combines global statistical analysis, observation data and regional case study assessments to yield new evidence for policy-makers.
Research on the effects of climate change on armed violence have previously been open to interpretation but new study shows climate-related disasters enhance armed conflict risks.
It's not too late to rescue global marine life, according to a study outlining the steps needed for marine ecosystems to recover from damage by 2050. University of Queensland scientist Professor Catherine Lovelock said the study found many components of marine ecosystems could be rebuilt if we try harder to address the causes of their decline.
Recycling orchard trees onsite can sequester carbon, save water and increase crop yields, making it a climate-smart practice for California's irrigated almond orchards, finds a study from the University of California, Davis.
Updated CT scoring criteria that considers lobe involvement, as well as changes in CT findings (i.e., ground-glass opacity, crazy-paving pattern, and consolidation), could quantitatively and accurately evaluate the progression of coronavirus disease (COVID-19) pneumonia, according to an open-access article in the American Journal of Roentgenology. "The earlier that COVID-19 is diagnosed and treated, the shorter the time to disease resolution and the lower the highest and last CT scores are," concluded lead author Guoquan Huang.
A major new study by an interdisciplinary team of researchers finds that it is possible -- and critical -- to bring industrial greenhouse gas emissions to net zero by 2070. Published Sunday in Applied Energy, the study assesses the range of technologies and policies interventions available to enable global industry decarbonization. This paper was the result of a collaboration among almost two dozen leading technical experts, led by Jeffrey Rissman of Energy Innovation and coauthored by Resources for the Future (RFF) Senior Fellow Dallas Burtraw.
New research published in Global Change Biology shows that some species have experienced a 75% population decrease in the past 60 years, while others are more than twice as abundant due to rises in sea surface temperatures.
In two new studies, scientists from the University of Turku, Finland, have investigated how to measure stress in semi-captive working elephants. The studies suggest that both physiological and behavioral approaches can be used to reliably assess the well-being of semi-captive Asian elephants.
