A University of Utah-led study found a surge in anti-Asian hate language on Twitter between January and March 2020, with clusters of hateful tweets spreading across the US. The researchers identified 15 geographic regions where anti-Asian hate was statistically higher than expected.
A new study reveals that urban residents have a simplistic understanding of coastal ecosystems and are less likely to take pro-environmental actions. The research highlights an issue known as urbanized knowledge syndrome, which can harm natural ecosystems and undermine community resilience.
A new approach for measuring physician adherence to best practices has been developed, taking into consideration patient characteristics and physician training background.
