Tanker traffic through the Strait of Hormuz declines for up to two years after a piracy attack, a new Duke University study finds, but the adverse effects of the slowdown affects some Persian Gulf countries more than others. Large exporters of crude oil, like Saudi Arabia, see little long-term impact, while smaller exporters, like Bahrain and Kuwait, can suffer disproportionate losses.
Transformative actions implemented by cities to address and mitigate the impacts of climate change may be hindered by political struggles for municipal power. This is clear from a study developed by researchers from the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) and the Pompeu Fabra University (UPF), published in the journal Cities.
Western Canada hosts a significant portion of North America's grizzly bears, and declining bear numbers have led to various conservation efforts. However, conservation policies frequently cause controversy. A new study examining the perspectives of local officials and residents in Alberta, Canada, suggests that locals feel excluded from decision-making processes underlying conservation policy, and have practical concerns with its implementation. Involving local people in designing conservation projects could help avoid such frustrations.
Nearly 94% of defendants in Cuyahoga County drug court have been exposed to trauma and many suffer from symptoms of post-traumatic stress disorder (PTSD), according to a new Case Western Reserve University study.
A new policy report, Electronic Registration Systems for Cooling Towers -- Improving Public Health and Sustainability Outcomes, published by the Urban Sustainability Directors Network (USDN) proposes a standardized yet flexible template for cooling tower registries that are designed to improve health outcomes, address disparity in affected populations, and increase water and energy efficiency.
Misleading portrayals of the safety of tobacco use are widespread on YouTube, where the viewership of popular pro-tobacco videos has soared over the past half-dozen years, according to research by the Annenberg Public Policy Center of the University of Pennsylvania.

In a new paper published in the leading scientific journal Current Biology, a team of neuroscientists of the Netherlands Institute for Neuroscience shows that male and female rats show harm aversion. This phenomenon depends on the same brain region associated with empathy in humans. This indicates that harm aversion is deeply engrained in our biology, and paves the way to future work on how to increase harm aversion in psychiatric diseases.
